    Gauthier, Diane

    Les problemes d'enseignement de la chimie des gaz parfaits sont donc importants. Si plusieurs etudes ont ete realisees dans le but d'identifier et d'interpreter ces problemes, aucune recherche, a notre connaissance, n'a ete realisee sur l'enseignement des lois sur les gaz parfaits. Notre recherche sur l'enseignement est donc pionniere. Elle a pour objectif general de construire et d'analyser une sequence d'enseignement de la chimie des gaz comportant diverses situations de modelisation mathematique des conduites des gaz. Les principaux objectifs specifiques sont les suivants: (1) identifier et caracteriser les situations qui provoquent une evolution des conceptions naives des eleves, evolution vers des connaissances plus adequate sur les gaz; (2) identifier et caractEriser les situations qui provoquent une evolution des connaissances mathematiques des eleves leur permettant d'interpreter convenablement les resultats des experiences, d'eprouver leurs conceptions, de donner un sens aux notions et aux relations impliquees dans les lois des gaz parfaits, lois de Boyle-Mariotte et Gay-Lussac. Une sequence d'enseignement comportant huit situations est d'eleves de secondaire V. La construction de ces situations est orientee par les recherches sur les conceptions naives des eleves, par les etudes sur l'evolution historique des conceptions sur les gaz et des pratiques scientifiques, ainsi que par les etudes theoriques et empiriques realisees en didactique des sciences et des mathematiques. La methodologie de l'ingenierie didactique (Artigue, 1998) qui constitue une application de la theorie des situations didactiques (Brousseau, 1986) est utilisee dans la construction et l'analyse des situations d'enseignement. Une analyse a priori de chacune des situations d'enseignement est effectuee; elle a pour but dexpliquer les choix des taches qui font partie des situations et de preciser la gestion didactique des situations. Diverses situations d'enseignement de la chimie ont ainsi

  4. Modelisation de la synthese reactive de poudres ultrafines dans un reacteur a plasma thermique

    Desilets, Martin

    La presente these s'inscrit dans le cadre de la modelisation mathematique des ecoulements a plasmas thermiques inertes et reactifs. Elle vise plus precisement a combler les lacunes des modeles existants en portant une attention particuliere aux phenomenes de transport multicomposant et a la prediction des transformations chimiques. Pour repondre a ces attentes et ainsi poursuivre le developpement dans ce domaine, un modele global a ete developpe. Il combine la resolution d'equations conservatives pour la masse, l'energie et le momentum. La generation d'un plasma inductif (h.f ) y est traitee au moyen d'equations representant les champs electromagnetiques. La nucleation et la croissance de poudres ultrafines sont incluses dans le modele via l'analyse des principaux moments de la distribution des tailles de particules. Enfin, tous les phenomenes physico-chimiques d'importance dans un milieu comme les plasmas thermiques, de meme que lem interactions, sont consideres. Le modele est applique ici a l'analyse de trois problematiques differentes et complementaires. La premiere concerne l'etude du melange gazeux d'un jet froid (He, N 2 ou O2), injecte au coeur d'une decharge d'argon/hydrogene ou d'argon/oxygene. La comparaison des predictions du modele avec des mesures experimentales obtenues par une sonde enthalpique permet une validation partielle de ce dernier. La deuxieme problematique a trait a l'etude numerique de la pyrolyse du methane en reacteur a plasma h.f. Elle met en evidence les difficultes de convergence de la methode numerique lorsque appliquee a la resolution d'ecoulements reactifs a haute temperature. Finalement, le dernier sujet aborde dans cette these, soit l'analyse systematique des principales conditions d'operation d'un reacteur h.f utilise pour la synthese reactive de poudres ultrafines de silicium, engage tous les elements theoriques du modele. Il implique en effet la decomposition thermique d'un precurseur gazeux, le tetrachlorure de silicium, la

Cette partie du manuscrit est composee de la derivation des equations, de l'ecriture d'un schema numerique associe a ce jeu d'equations, d'une etude d'ordre de ce schema ainsi que de simulations. Une etude mathematique de ce modele (hyperbolicite dans un cadre simplifie, stabilite du systeme lineaire autour d'un etat constant) a ete realisee dans un cadre ou le gaz est suppose barotrope. La seconde partie de ce manuscrit est consacree a la modelisation de l'effet de collisions inelastiques sur les gouttelettes lorsque l'on se place a un temps de simulation beaucoup plus court, pour lequel les gouttelettes ne peuvent plus etre vues comme un fluide. Pour modeliser ces collisions, on construit un modele simplifie (moins couteux en temps) de type BGK permettant de reproduire le comportement en temps de certains moments sur les gouttelettes. Ces moments sont choisis pour etre representatifs de l'effet des collisions sur ces gouttelettes, a savoir une thermalisation en vitesse et energie. Ce modele est discretise avec une methode particulaire et des resultats numeriques sont donnes en comparaison avec ceux obtenus avec un modele resolvant directement l'equation de Boltzmann homogene.

  7. Modelisation de la dynamique de la croissance dendritique des corps purs a la rupture de surfusion

    Science.gov (United States)

    Jaafar, Mohamad Ali

    est d'etudier la phase dendritique lors de la rupture de surfusion des materiaux a changement de phase. L'etude numerique s'appuie sur un code developpe en interne (en C++), qui resout le probleme de la croissance dendritique en modelisant l'evolution bidimensionnelle de l'interface liquide-solide en tenant compte de tous les effets thermodynamiques, geometriques, et thermiques. Le modele propose neglige la dependance des proprietes thermophysiques en temperature, ainsi que la convection thermique naturelle au sein du liquide. La resolution numerique est basee sur une approche de suivi explicite d'interface (front tracking method) a double maillage ; un maillage cartesien des volumes finis pour la resolution des equations de transferts thermiques dans les phases liquide et solide, et un maillage mobile completement independant d'ensemble des points discrets pour suivre le deplacement de l'interface. Dans un premier temps, le modele mathematique ainsi que les methodes de discretisation et de resolution mises en oeuvre sont presentes. La methode numerique ainsi que les techniques numeriques employees sont ensuite validees, d'une part, par un cas de solidification circulaire stable, ou les vitesses des points d'interface sont homogenes et l'interface reste stable et garde sa geometrie circulaire initiale, et d'autre part, par le concept du rayon critique de la nucleation homogene. Des cas instables, correspondants aux formes cristallines de " four-fold " et " six-fold ", sont presentes validant l'interaction des differents parametres. Enfin, l'evolution de l'interface ainsi que les phenomenes associes sont decrits en termes des effets d'anisotropie et des conditions thermiques locales. (Abstract shortened by ProQuest.).

    Ouellette, Jean-Michel

    Au Quebec, le decrochage scolaire cause par un manque de motivation de la part des eleves est une preoccupation actuelle. Dans une societe de savoirs ou les technologies prennent une place de plus en plus grande, il apparait important d'explorer toutes les pistes de travail quant a l'amelioration de la motivation scolaire des jeunes. Plus precisement, sachant qu'il existe des liens concrets entre la programmation informatique et les mathematiques, nous avons analyse l'apport possible de l'apprentissage de la programmation informatique a la motivation pour l'apprentissage des mathematiques. Trois eleves de troisieme secondaire ont participe a cette etude multicas. Selon les resultats d'analyse, tous les eleves ont vecu une amelioration de leur motivation a apprendre les mathematiques. A la lumiere de l'analyse de ces resultats, nous proposons une explication relativement aux liens possibles entre la participation des eleves a une activite parascolaire de programmation informatique et l'amelioration de leur motivation pour l'apprentissage des mathematiques.

  9. Flow and heat transfer thermohydraulic modelisation during the reflooding phase of a P.W.R.'s core

    International Nuclear Information System (INIS)

    Raymond, Patrick

    1978-04-01

    Some generalities about L.O.C.A. are first recalled. The French experimental studies about Emergency Core Cooling System are briefly described. The different heat transfer mechanisms to take into account, according to the flow pattern in the dry zone, and the correlations or methods to calculate them, are defined. Then the Thermohydraulic code computer: FLIRA, which describe the reflooding phase, and a modelisation taking into account the different flow patterns are setted. A first interpretation of ERSEC experiments with a tubular test section shows that it is possible, with this modelisation and some classical heat transfer correlations, to describe the reflooding phase.

  10. Modelisation of the growth of extended defects created by electron irradiation in CdTe

    Gue, A.M.; Esteve, D.; Mazel, A.

    1989-01-01

    After a brief review of the experimental features of dislocation loops created in cadmium telluride by high energy electron irradiation, we present a theoretical modelisation of the growth of extended defects. The basic method of the Chemical Reaction Rate Theory has been modified in order to take into account: the instability of small clusters, the effects of surfaces, the fact that CdTe is a binary compound. The comparison between theoretical and experimental results leads us to conclude that the vacancy-interstitial recombination energy (E v ) is different from the diinterstitial formation energy (E i ). The values of these energies have been determined: E i =.35eV, E v =.25eV, E d =1.1eV (small clusters dissociation energy). This work has also shown that the lake of dislocation loops at high irradiation temperature (T>480K) is not only a thin film effect but is due to clusters instability [fr

    Due to safety rules running on fourth generation reactors' core development, neutronics simulation tools have to be as accurate as never before. First part of this report enumerates every step of fast reactor's neutronics simulation implemented in current reference code: ECCO. Considering the field of fast reactors that meet criteria of fourth generation, ability of models to describe self-shielding phenomenon, to simulate neutrons leakage in a lattice of fuel assemblies and to produce representative macroscopic sections is evaluated. The second part of this thesis is dedicated to the simulation of fast reactors' core with steel reflector. These require the development of advanced methods of condensation and homogenization. Several methods are proposed and compared on a typical case: the ZONA2B core of MASURCA reactor. (author) [French] Les criteres de surete qui regissent le developpement de coeurs de reacteurs de quatrieme generation implique l'usage d'outils de calcul neutronique performants. Une premiere partie de la these reprend toutes les etapes de modelisation neutronique des reacteurs rapides actuellement d'usage dans le code de reference ECCO. La capacite des modeles a decrire le phenomene d'autoprotection, a representer les fuites neutroniques au niveau d'un reseau d'assemblages combustibles et a generer des sections macroscopiques representatives est appreciee sur le domaine des reacteurs rapides innovants respectant les criteres de quatrieme generation. La deuxieme partie de ce memoire se consacre a la modelisation des coeurs rapides avec reflecteur acier. Ces derniers necessitent le developpement de methodes avancees de condensation et d'homogenisation. Plusieurs methodes sont proposees et confrontees sur un probleme de modelisation typique: le coeur ZONA2B du reacteur maquette MASURCA

    Science.gov (United States)

    Bourdi, Taoufik

    Le georadar (Ground Penetrating Radar (GPR)) constitue une technique de controle non destructif (CND) interessante pour la mesure des epaisseurs des dalles de beton et la caracterisation des fractures, en raison de ses caracteristiques de resolution et de profondeur de penetration. Les equipements georadar sont de plus en plus faciles a utiliser et les logiciels d'interpretation sont en train de devenir plus aisement accessibles. Cependant, il est ressorti dans plusieurs conferences et ateliers sur l'application du georadar en genie civil qu'il fallait poursuivre les recherches, en particulier sur la modelisation et les techniques de mesure des proprietes electriques du beton. En obtenant de meilleures informations sur les proprietes electriques du beton aux frequences du georadar, l'instrumentation et les techniques d'interpretation pourraient etre perfectionnees plus efficacement. Le modele de Jonscher est un modele qui a montre son efficacite dans le domaine geophysique. Pour la premiere fois, son utilisation dans le domaine genie civil est presentee. Dans un premier temps, nous avons valide l'application du modele de Jonscher pour la caracterisation de la permittivite dielectrique du beton. Les resultats ont montre clairement que ce modele est capable de reproduire fidelement la variation de la permittivite de differents types de beton sur la bande de frequence georadar (100 MHz-2 GHz). Dans un deuxieme temps, nous avons montre l'interet du modele de Jonscher en le comparant a d'autres modeles (Debye et Debye-etendu) deja utilises dans le domaine genie civil. Nous avons montre aussi comment le modele de Jonscher peut presenter une aide a la prediction de l'efficacite de blindage et a l'interpretation des ondes de la technique GPR. Il a ete determine que le modele de Jonscher permet de donner une bonne presentation de la variation de la permittivite du beton dans la gamme de frequence georadar consideree. De plus, cette modelisation est valable pour differents

    Richard, Marc-Andre

    2009-12-01

    Nos travaux sur l'adsorption de gaz dans les materiaux microporeux s'inscrivent dans le cadre des recherches visant a augmenter l'efficacite du stockage de l'hydrogene a bord des vehicules. Notre objectif etait d'etudier la possibilite d'utiliser l'adsorption afin d'ameliorer l'efficacite de la liquefaction de l'hydrogene des systemes a petite echelle. Nous avons egalement evalue les performances d'un systeme de stockage cryogenique de l'hydrogene base sur la physisorption. Comme nous avons affaire a des plages de temperatures particulierement etendues et a de hautes pressions dans la region supercritique du gaz, nous avons du commencer par travailler sur la modelisation et la thermodynamique de l'adsorption. La representation de la quantite de gaz adsorbee en fonction de la temperature et de la pression par un modele semi-empirique est un outil utile pour determiner la masse de gaz adsorbee dans un systeme mais egalement pour calculer les effets thermiques lies a l'adsorption. Nous avons adapte le modele Dubinin-Astakhov (D-A) pour modeliser des isothermes d'adsorption d'hydrogene, d'azote et de methane sur du charbon actif a haute pression et sur une grande plage de temperatures supercritiques en considerant un volume d'adsorption invariant. Avec cinq parametres de regression (incluant le volume d'adsorption Va), le modele que nous avons developpe permet de tres bien representer des isothermes experimentales d'adsorption d'hydrogene (de 30 a 293 K, jusqu'a 6 MPa), d'azote (de 93 a 298 K, jusqu'a 6 MPa) et de methane (de 243 a 333 K, jusqu'a 9 MPa) sur le charbon actif. Nous avons calcule l'energie interne de la phase adsorbee a partir du modele en nous servant de la thermodynamique des solutions sans negliger le volume d'adsorption. Par la suite, nous avons presente les equations de conservation de la niasse et de l'energie pour un systeme d'adsorption et valide notre demarche en comparant des simulations et des tests d'adsorption et de desorption.

  20. Modelisation numerique et validation experimentale d'un systeme de protection contre le givre par elements piezoelectriques

    Science.gov (United States)

    Harvey, Derek

    Le degivrage au moyen d'actuateurs piezoelectriques est considere comme une avenue prometteuse pour le developpement de systemes a faible consommation d'energie applicables aux helicopteres legers. Ce type de systeme excite des frequences de resonances d'une structure pour produire des deformations suffisantes pour rompre l'adherence de la glace. Par contre, la conception de tel systeme demeure generalement mal comprise. Ce projet de maitrise etudie l'utilisation de methodes numeriques pour assister la conception des systemes de protection contre le givre a base d'elements piezoelectriques. La methodologie retenue pour ce projet a ete de modeliser differentes structures simples et de simuler l'excitation harmonique des frequences de resonance au moyen d'actuateurs piezoelectriques. Le calcul des frequences de resonances ainsi que la simulation de leur excitation a ensuite ete validee a l'aide de montages experimentaux. La procedure a ete realisee pour une poutre en porte-a-faux et pour une plaque plane a l'aide du logiciel de calcul par elements finis, Abaqus. De plus, le modele de la plaque plane a ete utilise afin de realiser une etude parametrique portant sur le positionnement des actuateurs, l'effet de la rigidite ainsi que de l'epaisseur de la plaque. Finalement, la plaque plane a ete degivree en chambre climatique. Des cas de degivrage ont ete simules numeriquement afin d'etudier la possibilite d'utiliser un critere base sur la deformation pour predire le succes du systeme. La validation experimentale a confirme la capacite du logiciel a calculer precisement a la fois les frequences et les modes de resonance d'une structure et a simuler leur excitation par des actuateurs piezoelectriques. L'etude revele que la definition de l'amortissement dans le modele numerique est essentiel pour l'obtention de resultats precis. Les resultats de l'etude parametrique ont demontre l'importance de minimiser l'epaisseur et la rigidite afin de reduire la valeur des frequences

  1. Comparison of ensemble post-processing approaches, based on empirical and dynamical error modelisation of rainfall-runoff model forecasts

    2012-04-01

    In the context of a national energy company (EDF : Electricité de France), hydro-meteorological forecasts are necessary to ensure safety and security of installations, meet environmental standards and improve water ressources management and decision making. Hydrological ensemble forecasts allow a better representation of meteorological and hydrological forecasts uncertainties and improve human expertise of hydrological forecasts, which is essential to synthesize available informations, coming from different meteorological and hydrological models and human experience. An operational hydrological ensemble forecasting chain has been developed at EDF since 2008 and is being used since 2010 on more than 30 watersheds in France. This ensemble forecasting chain is characterized ensemble pre-processing (rainfall and temperature) and post-processing (streamflow), where a large human expertise is solicited. The aim of this paper is to compare 2 hydrological ensemble post-processing methods developed at EDF in order improve ensemble forecasts reliability (similar to Monatanari &Brath, 2004; Schaefli et al., 2007). The aim of the post-processing methods is to dress hydrological ensemble forecasts with hydrological model uncertainties, based on perfect forecasts. The first method (called empirical approach) is based on a statistical modelisation of empirical error of perfect forecasts, by streamflow sub-samples of quantile class and lead-time. The second method (called dynamical approach) is based on streamflow sub-samples of quantile class and streamflow variation, and lead-time. On a set of 20 watersheds used for operational forecasts, results show that both approaches are necessary to ensure a good post-processing of hydrological ensemble, allowing a good improvement of reliability, skill and sharpness of ensemble forecasts. The comparison of the empirical and dynamical approaches shows the limits of the empirical approach which is not able to take into account hydrological

    2016-04-01

    The Mediterranean region is affected by water scarcity. Some countries as Tunisia reached the limit of 550 m3/year/capita due overexploitation of low water resources for irrigation, domestic uses and industry. A lot of programs aim to evaluate strategies to improve water consumption at regional level. In central Tunisia, on the Merguellil catchment, we develop integrated water resources modelisations based on social investigations, ground observations and remote sensing data. The main objective is to close the water budget at regional level and to estimate irrigation and water pumping to test scenarios with endusers. Our works benefit from French, bilateral and European projects (ANR, MISTRALS/SICMed, FP6, FP7…), GMES/GEOLAND-ESA) and also network projects as JECAM and AERONET, where the Merguellil site is a reference. This site has specific characteristics associating irrigated and rainfed crops mixing cereals, market gardening and orchards and will be proposed as a new environmental observing system connected to the OMERE, TENSIFT and OSR systems respectively in Tunisia, Morocco and France. We show here an original and large set of ground and remote sensing data mainly acquired from 2008 to present to be used for calibration/validation of water budget processes and integrated models for present and scenarios: - Ground data: meteorological stations, water budget at local scale: fluxes tower, soil fluxes, soil and surface temperature, soil moisture, drainage, flow, water level in lakes, aquifer, vegetation parameters on selected fieds/month (LAI, height, biomass, yield), land cover: 3 times/year, bare soil roughness, irrigation and pumping estimations, soil texture. - Remote sensing data: remote sensing products from multi-platform (MODIS, SPOT, LANDSAT, ASTER, PLEIADES, ASAR, COSMO-SkyMed, TerraSAR X…), multi-wavelength (solar, micro-wave and thermal) and multi-resolution (0.5 meters to 1 km).

    Palladium is commonly used for the storage of tritium (the hydrogen radioactive isotope), since it forms a low-equilibrium-pressure and reversible tritide. Tritium decay into helium-3 is responsible for the ageing of the tritide, leading to the apparition of helium-3 bubbles for instance. Both experimental and theoretical aspects of this phenomenon are studied here.Previous works on ageing modelling led to two main models, dealing with:- Helium-3 bubbles nucleation (using a cellular automaton), - Bubbles growth (using continuum mechanics).These models were quite efficient, but their use was limited by the lack of input data and fitting experimental parameters.To get through these limitations, this work has consisted in studying the most relevant experimental data to improve the modelling of the palladium tritide ageing.The first part of this work was focused on the assessment of the mechanical properties of the palladium tritide (yield strength, ultimate strength, mechanical behaviour). They were deduced from the in situ tensile tests performed on palladium hydride and deuteride. In the second part, ageing characterization was undertaken, mainly focusing on: - Bubbles observations in palladium tritide using transmission electron microscopy, - Internal bubble pressure measurements using nuclear magnetic resonance, - Macroscopic swelling measurements using pycno-metry.The present work has led to significant progress in ageing understanding and has brought very valuable improvements to the modelling of such a phenomenon.

    Boyer, Sylvain

    methode des seuils auditifs REAT (Real Ear Attenuation Threshold) aussi vu comme un "golden standard" est utilise pour quantifier la reduction du bruit mais surestime generalement la performance des protecteurs. Les techniques de mesure terrains, telles que la F-MIRE (Field Measurement in Real Ear) peuvent etre a l'avenir de meilleurs outils pour evaluer l'attenuation individuelle. Si ces techniques existent pour des bouchons d'oreilles, elles doivent etre adaptees et ameliorees pour le cas des coquilles, en determinant l'emplacement optimal des capteurs acoustiques et les facteurs de compensation individuels qui lient la mesure microphonique a la mesure qui aurait ete prise au tympan. La troisieme problematique specifique est l'optimisation de l'attenuation des coquilles pour les adapter a l'individu et a son environnement de travail. En effet, le design des coquilles est generalement base sur des concepts empiriques et des methodes essais/erreurs sur des prototypes. La piste des outils predictifs a ete tres peu etudiee jusqu'a present et meriterait d'etre approfondie. L'utilisation du prototypage virtuel, permettrait a la fois d'optimiser le design avant production, d'accelerer la phase de developpement produit et d'en reduire les couts. L'objectif general de cette these est de repondre a ces differentes problematiques par le developpement d'un modele de l'attenuation sonore d'un protecteur auditif de type coquille. A cause de la complexite de la geometrie de ces protecteurs, la methode principale de modelisation retenue a priori est la methode des elements finis (FEM). Pour atteindre cet objectif general, trois objectifs specifiques ont ete etablis et sont presentes dans les trois paragraphes suivants. (Abstract shortened by ProQuest.).

  7. Modelisation geometrique par NURBS pour le design aerodynamique des ailes d'avion

    Bentamy, Anas

    The constant evolution of the computer science gives rise to many research areas especially in computer aided design. This study is part, of the advancement of the numerical methods in engineering computer aided design, specifically in aerospace science. The geometric modeling based on NURBS has been applied successfully to generate a parametric wing surface for aerodynamic design while satisfying manufacturing constraints. The goal of providing a smooth geometry described with few parameters has been achieved. In that case, a wing design including ruled surfaces at the leading edge slat and at the flap, and, curved central surfaces with intrinsic geometric property coming from conic curves, necessitates 130 control points and 15 geometric design variables. The 3D character of the wing need to be analyzed by techniques of investigation of surfaces in order to judge conveniently the visual aspect and detect any sign inversion in both directions of parametrization u and nu. Color mapping of the Gaussian curvature appears to be a very effective tools in visualization. The automation of the construction has been attained using an heuristic optimization algorithm, simulated annealing. The relative high speed of convergence to the solutions confirms its practical interest in engineering problems nowadays. The robustness of the geometric model has been tested successfully with an academic inverse design problem. The results obtained allow to foresee multiple possible applications from an extension to a complete geometric description of an airplane to the interaction with others disciplines belonging to a preliminary aeronautical design process.

    Belhadj Youssef, Nesrine

    Les problemes de la qualite de l'onde electrique constituent l'une des preoccupations majeures des fournisseurs de l'energie et des organismes specialises en qualite d'energie. Ce sujet a gagne davantage d'ampleur avec l'utilisation ascendante des convertisseurs de l'energie electrique dans la majorite des applications industrielles et domestiques. Dans le cadre de cette these, on s'interesse plus particulierement au type des convertisseurs alternatif/continu, dont le fonctionnement adequat implique la parfaite regulation du bus DC de tension, l'attenuation des harmoniques de courants, la compensation de l'energie reactive et la maximisation du rendement energetique. Ces differents criteres doivent etre maintenus pour diverses conditions de fonctionnement, c'est-a-dire independamment des variations parametriques auxquelles le systeme peut etre sujet. Il s'avere donc indispensable d'adopter des techniques de commande efficaces, ce qui passe par une modelisation correcte du convertisseur. L'optimisation du nombre de capteurs dans le circuit est egalement un facteur cle a prendre en consideration.

  12. Methodologie de modelisation aerostructurelle d'une aile utilisant un logiciel de calcul aerodynamique et un logiciel de calcul par elements finis =

    Communier, David

    Lors de l'etude structurelle d'une aile d'avion, il est difficile de modeliser fidelement les forces aerodynamiques subies par l'aile de l'avion. Pour faciliter l'analyse, on repartit la portance maximale theorique de l'aile sur son longeron principal ou sur ses nervures. La repartition utilisee implique que l'aile entiere sera plus resistante que necessaire et donc que la structure ne sera pas totalement optimisee. Pour pallier ce probleme, il faudrait s'assurer d'appliquer une repartition aerodynamique de la portance sur la surface complete de l'aile. On serait donc en mesure d'obtenir une repartition des charges sur l'aile beaucoup plus fiable. Pour le realiser, nous aurons besoin de coupler les resultats d'un logiciel calculant les charges aerodynamiques de l'aile avec les resultats d'un logiciel permettant sa conception et son analyse structurelle. Dans ce projet, le logiciel utilise pour calculer les coefficients de pression sur l'aile est XFLR5 et le logiciel permettant la conception et l'analyse structurelle sera CATIA V5. Le logiciel XFLR5 permet une analyse rapide d'une aile en se basant sur l'analyse de ses profils. Ce logiciel calcule les performances des profils de la meme maniere que XFOIL et permet de choisir parmi trois methodes de calcul pour obtenir les performances de l'aile : Lifting Line Theory (LLT), Vortex Lattice Method (VLM) et 3D Panels. Dans notre methodologie, nous utilisons la methode de calcul 3D Panels dont la validite a ete testee en soufflerie pour confirmer les calculs sur XFLR5. En ce qui concerne la conception et l'analyse par des elements finis de la structure, le logiciel CATIA V5 est couramment utilise dans le domaine aerospatial. CATIA V5 permet une automatisation des etapes de conception de l'aile. Ainsi, dans ce memoire, nous allons decrire la methodologie permettant l'etude aerostructurelle d'une aile d'avion.

    Data science has attracted a lot of attention, promising to turn vast amounts of data into useful predictions and insights. In this article, we ask why scientists should care about data science. To answer, we discuss data science from three perspectives: statistical, computational, and human. Although each of the three is a critical component of data science, we argue that the effective combination of all three components is the essence of what data science is about.

    ) using a procedure similar to the physical theory of diffraction (PTD). The refined KA provides an improvement of the prediction in the near field of a rigid scatterer. The initial (non refined) KA model is then extended to deal with the scattering from a finite impedance target. The obtained model, the so-called 'general' KA model, is a satisfactory solution for the application to telemetry. Finally, the coupling of the stochastic propagation model and the general KA diffraction model has allowed us to build a complete simulation tool for the telemetry in an inhomogeneous medium. (author) [French] Cette etude s'inscrit dans le cadre du developpement d'outils de simulation de la telemetrie qui est une technique possible pour la surveillance et le controle periodique des reacteurs nucleaires a neutrons rapides refroidis par du sodium liquide (RNR-Na). De maniere generale, la telemetrie consiste a positionner au sein du reacteur un transducteur qui genere un faisceau ultrasonore. Ce faisceau se propage a travers un milieu inhomogene et aleatoire car le sodium liquide est le siege de fluctuations de temperature qui impliquent une variation de la celerite des ondes ultrasonores, ce qui modifie la propagation du faisceau. Ce dernier interagit ensuite avec une structure immergee dans le reacteur. La mesure du temps de vol de l'echo recu par le meme transducteur permet de determiner la position precise de la structure. La simulation complete de la telemetrie necessite donc la modelisation a la fois de la propagation d'une onde acoustique en milieu inhomogene aleatoire et de l'interaction de cette onde avec des cibles de formes variees; c'est l'objectif de ce travail. Un modele stochastique base sur un algorithme de type Monte-Carlo est tout d'abord developpe afin de simuler les perturbations aleatoires du champ de propagation.

    The remote-controlled helicopter remains an interesting topic for research in flight control. This kind of machine, easy to deploy due to their small size, is an ideal candidate to test multiple flight control algorithms. To better understand the dynamics of flight of this vehicle, it is important to have a mathematical model. This thesis follows the logic of obtaining a mathematical model for a stationary hovering helicopter. This thesis aims to provide a testbench for the identification of a mathematical model of a small helicopter and for the application of different flight control laws. First, a review on the identification theory is introduced. The methods presented are applicable to multivariable systems. A particular focus is on the identification of state models. The theory concludes with the presentation of algorithms used in the Matlab/Simulink software. Second, a mathematical model of the helicopter is developed. As part of our research, hypotheses to reduce the model are presented. This model is the basis for determining the right identification methods. The mathematical model provides a guideline for specifying the various components of the test bench. The thesis continues with the presentation of the avionics used in the project. The instrumentation is presented in two parts: the hardware and the software. The acquisition of real-time flight parameters is also presented. Finally, the use of the test bench is detailed for the ground tests and for the flight tests. These tests are designed to collect the data necessary for the deployment of various identification techniques. The thesis concludes with comments on significants results and suggestions of prospects for improving the test bench.

    Science literacy is imperative for well informed civic and personal decision making, yet only a quarter of American adults are proficient enough in science to understand science stories reported in the popular press. Hands-on research increases confidence in and understanding of science. When guiding students in designing and conducting science fair projects, mentors can foster science literacy by helping students focus on three goals: (1) articulating hypotheses or questions, (2) designing feasible projects, and (3) learning to make and interpret graphs. These objectives introduce students to the methodological nature of scientific research and give them the tools to interpret scientific facts and data in order to make informed decisions for themselves and society.

    Full Text Available On rare occasions in the history of science, remarkable discoveries transform human society and forever alter mankind’s view of the world. Examples of such discoveries include the heliocentric theory, Newtonian physics, the germ theory of disease, quantum theory, plate tectonics and the discovery that DNA carries genetic information. The science philosopher Thomas Kuhn famously described science as long periods of normality punctuated by times of crisis, when anomalous observations culminate in revolutionary changes that replace one paradigm with another. This essay examines several transformative discoveries in the light of Kuhn’s formulation. We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported.

We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported.

    Evans, Robert G

    2009-05-01

    "No prediction, no science." By this standard, the past year has not been kind to the pretensions of "economic science," Nobel prizes notwithstanding. The issue is more than semantic. As Neil Postman (1992) pointed out, sciences study natural processes that repeat themselves under constant conditions. The social disciplines study practices of human communities that are embedded in history. There are no constant conditions; it is impossible to step into the same river twice (Heraclitus). "Physics envy" has led mainstream economic theorists to attempt to understand their discipline through methods and models borrowed from the natural sciences. (By unfortunate coincidence, these have reinforced a certain class of ideological preconceptions and associated economic interests.) Today the results of this methodological mismatch speak for themselves.

    How does Einstein’s description of space and time compare with Dr. Who? Can James Bond really escape from an armor-plated railroad car by cutting through the floor with a laser concealed in a wristwatch? What would it take to create a fully-intelligent android, such as Star Trek’s Commander Data? How might we discover intelligent civilizations on other planets in the galaxy? Is human teleportation possible? Will our technological society ever reach the point at which it becomes lawful to discriminate on the basis of genetic information, as in the movie GATTACA? Exploring Science Through Science Fiction addresses these and other interesting questions, using science fiction as a springboard for discussing fundamental science concepts and cutting-edge science research.

    Our experience in the development of numerous knowledge based control systems for large industrial applications has led us to the expression of a generic problem and to the implementation of the tools to address it. This paper illustrates, with different practical examples that we have encountered, the principal concepts found in the modelling and management of large industrial knowledge bases. We thus arrive at the definition of the formalism to be used. The principles described are now integrated into the tool SPIRAL and are currently being employed in the development of several applications

    Our science is critical to understanding the future prospects for life. The laboratory for natural sciences encompasses our planet and reaches into the solar system. The forces of nature respect no boundaries. But, we who try to understand these forces are handicapped by national, political, language, religious, and other concocted barriers. These barriers limit both our effectiveness as scientists and our ability to reach those outside our community who need to know what we have uncovered about our environment. An unencumbered worldwide scientific community has been an objective with limited successes for too long. Action began in earnest after the first world war with the formation of the various scientific Unions and ICSU. Fifty years later Keith Runcorn initiated another approach, when he proposed what quickly became EGS and which has grown and evolved with the merger with EUG. To be truly effective we need to communicate and share comfortably with colleagues worldwide. Personal relationships and trust are required. We count on a high level of ethical behavior within our community. We individually must also be constantly vigilant for the encroachment of the manmade barriers that have held back science through time immemorial. Our scientific organizations cannot achieve this alone. They will facilitate, however, the onus is on each of us to reach out and form interlocking informal communities, which will bring our whole planet-wide community together at many overlapping levels. When we achieve this community, our science will more bountiful and better address the needs of human society.

    1997-01-01

    What is good science? What goal--if any--is the proper end of scientific activity? Is there a legitimating authority that scientists mayclaim? Howserious athreat are the anti-science movements? These questions have long been debated but, as Gerald Holton points out, every era must offer its own responses. This book examines these questions not in the abstract but shows their historic roots and the answers emerging from the scientific and political controversies of this century. Employing the case-study method and the concept of scientific thematathat he has pioneered, Holton displays the broad scope of his insight into the workings of science: from the influence of Ernst Mach on twentiethcentury physicists, biologists, psychologists, and other thinkers to the rhetorical strategies used in the work of Albert Einstein, Niels Bohr, and others; from the bickering between Thomas Jefferson and the U.S. Congress over the proper form of federal sponsorship of scientific research to philosophical debates since Oswald...

    2014-04-01

    As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

    Holland, G. J.; McCaffrey, M. S.; Kiehl, J. T.; Schmidt, C.

    2010-12-01

    We are in an era of rapidly changing communication media, which is driving a major evolution in the modes of communicating science. In the past, a mainstay of scientific communication in popular media was through science “translators”; science journalists and presenters. These have now nearly disappeared and are being replaced by widespread dissemination through, e.g., the internet, blogs, YouTube and journalists who often have little scientific background and sharp deadlines. Thus, scientists are required to assume increasing responsibility for translating their scientific findings and calibrating their communications to non-technical audiences, a task for which they are often ill prepared, especially when it comes to controversial societal issues such as tobacco, evolution, and most recently climate change (Oreskes and Conway 2010). Such issues have been politicized and hi-jacked by ideological belief systems to such an extent that constructive dialogue is often impossible. Many scientists are excellent communicators, to their peers. But this requires careful attention to detail and logical explanation, open acknowledgement of uncertainties, and dispassionate delivery. These qualities become liabilities when communicating to a non-scientific audience where entertainment, attention grabbing, 15 second sound bites, and self assuredness reign (e.g. Olson 2009). Here we report on a program initiated by NCAR and UCAR to develop new approaches to science communication and to equip present and future scientists with the requisite skills. If we start from a sound scientific finding with general scientific consensus, such as the warming of the planet by greenhouse gases, then the primary emphasis moves from the “science” to the “art” of communication. The art cannot have free reign, however, as there remains a strong requirement for objectivity, honesty, consistency, and above all a resistance to advocating particular policy positions.

    The DOE laboratories play a unique role in bringing multidisciplinary talents -- in biology, physics, chemistry, computer sciences, and engineering -- to bear on major problems in the life and environmental sciences. Specifically, the laboratories utilize these talents to fulfill OHER`s mission of exploring and mitigating the health and environmental effects of energy use, and of developing health and medical applications of nuclear energy-related phenomena. At Lawrence Berkeley Laboratory (LBL) support of this mission is evident across the spectrum of OHER-sponsored research, especially in the broad areas of genomics, structural biology, basic cell and molecular biology, carcinogenesis, energy and environment, applications to biotechnology, and molecular, nuclear and radiation medicine. These research areas are briefly described.

    The DOE laboratories play a unique role in bringing multidisciplinary talents -- in biology, physics, chemistry, computer sciences, and engineering -- to bear on major problems in the life and environmental sciences. Specifically, the laboratories utilize these talents to fulfill OHER's mission of exploring and mitigating the health and environmental effects of energy use, and of developing health and medical applications of nuclear energy-related phenomena. At Lawrence Berkeley Laboratory (LBL) support of this mission is evident across the spectrum of OHER-sponsored research, especially in the broad areas of genomics, structural biology, basic cell and molecular biology, carcinogenesis, energy and environment, applications to biotechnology, and molecular, nuclear and radiation medicine. These research areas are briefly described.

    Full Text Available The nanometer regime covers the transition from condensed matter behavior to atomic and molecular properties and thus is a very rich but also very demanding area in materials science. Close to the condensed matter side, properties and functions might still very well be scalable, whereas close to the atomic and molecular side, the scalability is mostly lost. Properties and functions change qualitatively or quantitatively by orders of magnitude when the dimensions become smaller than a critical size in the nanometer range. Examples are the ballistic regime for electron or spin transport at dimensions below the mean free path, near-field effects in scanning near-field optical microscopy and quantum wells when the dimensions are below an appropriate wavelength, novel electronic, mechanical, and chemical properties when the number of bulk atoms becomes smaller than that of surface atoms, quantum conduction, and Coulomb blockade. Thus, by going below a certain size, an abundance of novel properties and functions are at one's disposal, or, in other words, we can functionalize materials simply by reducing their size to the nanoscale.The key to the future lies in the functions that we give to materials, not just in finding 'novel functional materials'. This catch expression in many materials science programs and initiatives of the past two decades sounds great, but it is not what really counts. All materials are functional in one way or another and, therefore, all new materials are 'novel functional materials'. Certainly, finding new materials is always an important part of progress, but we should also focus on the much larger domain of novel functions that we can give to existing or modified materials. A good example is semiconductors: they are fifty or more years old and their properties are very well known, but they were not of widespread interest and use until the transistor changed their destiny into being the central material in the information

    2013-07-01

    Science kitsch? The combination of these two words rings like an oxymoron. Science - as the common saying has it - exposes, discovers, tells the truth; kitsch conceals, covers, lies. I think, this "shadow" of science deserves a specific scrutiny, not only because it reflects the altered place and role of science in contemporary "knowledge" society but also because it pinpoints the task of relocating science in the "multicultural" context of postmodernism, with its different epistemic claims. The genre of science kitsch may help to regain credit by working as a probe to detect false pretensions, explanatory exuberance and exaggerations in science.

  9. Enacting science

    Science.gov (United States)

    MacDonald, Anthony Leo

    My study examines the development of forms of knowing that arise when students engage in open-ended explorations involving self-directed design and building involving simple materials. It is grounded in an enactivist theoretical perspective on cognition which holds that the creation of action-thought processes for engaging the world is interwoven with the meanings that are constructed for these experiences. A dynamic conception of persons-acting-in-a-setting is fundamental to an enactivist view of cognition. How is understanding enacted in building activity? How does the shape of a problem emerge? How do students enact meaning and understanding when they experience a high degree of physical engagement in building things? What are some characteristics of an enactive learning/teaching environment? My research settings comprise a range of individual, group and classroom engagements of varying lengths over a three and one-half year period. The first research episode involved two grade eight students in an investigation of Paper Towels. The second four month engagement was in a grade nine science class that culminated in the building of a Solar House. The third grade ten episode involved a one month project to build a Mousetrap Powered Car. A fourth Invent a Machine project was conducted in two grade eight science classes taught by the teacher who participated in the Solar House project. Two students were present in three of the four projects. I interviewed one of these students upon completion of his high school physics courses. I found that building is a form of thinking which develops competency in managing complex practical tasks. A triadic relationship of exploration, planning and acting is present. Practical and procedural understandings emerge as students enter and re-enter self-directed problem settings. Thinking patterns depend on the kinds of materials chosen, the ways they are used, and on how students contextualize the problem. Classroom assessment

    In contemporary research, the supercomputer now ranks, along with radio telescopes, particle accelerators and the other apparatus of "big science", as an expensive resource, which is nevertheless essential for state of the art research. Supercomputers are usually provided as shar.ed central facilities. However, unlike, telescopes and accelerators, they are find a wide range of applications which extends across a broad spectrum of research activity. The difference in performance between a "good" and a "bad" computer program on a traditional serial computer may be a factor of two or three, but on a contemporary supercomputer it can easily be a factor of one hundred or even more! Furthermore, this factor is likely to increase with future generations of machines. In keeping with the large capital and recurrent costs of these machines, it is appropriate to devote effort to training and familiarization so that supercomputers are employed to best effect. This volume records the lectures delivered at a Summer School ...

    Natural scientists from Climate Central and social scientists from Carnegie Mellon University collaborated to develop science communications aimed at presenting personalized coastal flood risk information to the public. We encountered four main challenges: agreeing on goals; balancing complexity and simplicity; relying on data, not intuition; and negotiating external pressures. Each challenge demanded its own approach. We navigated agreement on goals through intensive internal communication early on in the project. We balanced complexity and simplicity through evaluation of communication materials for user understanding and scientific content. Early user test results that overturned some of our intuitions strengthened our commitment to testing communication elements whenever possible. Finally, we did our best to negotiate external pressures through regular internal communication and willingness to compromise.

  13. Applications of Nuclear Science for Stewardship Science

    Cizewski, Jolie A

    2013-01-01

    Stewardship science is research important to national security interests that include stockpile stewardship science, homeland security, nuclear forensics, and non-proliferation. To help address challenges in stewardship science and workforce development, the Stewardship Science Academic Alliances (SSAA) was inaugurated ten years ago by the National Nuclear Security Administration of the U. S. Department of Energy. The goal was to enhance connections between NNSA laboratories and the activities of university scientists and their students in research areas important to NNSA, including low-energy nuclear science. This paper presents an overview of recent research in low-energy nuclear science supported by the Stewardship Science Academic Alliances and the applications of this research to stewardship science.

    Science.gov (United States)

    Summ, Annika; Volpers, Anna-Maria

    2016-10-01

    This article examines the current state of science coverage in German print media. It deals with the following questions: (1) how the main characteristics of science journalism can be described, (2) whether there is a difference between various scientific fields, and (3) how different definitions of science journalism lead to differing findings. Two forms of science coverage were analyzed in a standardized, two-part content analysis of German newspapers (N = 1730 and N = 1640). The results show a significant difference between a narrow and a broad definition of science journalism. In the classic understanding, science journalism is prompted by scientific events and is rather noncritical. Science coverage in a broad sense is defined by a wider range of journalistic styles, driven by non-scientific events, and with a focus on the statements of scientific experts. Furthermore, the study describes the specific role of the humanities and social sciences in German science coverage. © The Author(s) 2015.

Its express purpose is to develop common theoretical underpinnings to better solve modern infrastructural problems. It is felt by many who work in these fields that many modern communication problems, ranging from transportation networks to telecommunications, Internet, supply chains, etc., are fundamentally infrastructure problems. Moreover, these infrastructure problems would benefit greatly from a confluence of theoretical and methodological work done with the areas of Network Science, Dynamical Systems and Nonlinear Science. This book is dedicated to the formulation of infrastructural tools that will better solve these types of infrastructural problems. .

  1. Science and religion: implications for science educators

    Science.gov (United States)

    Reiss, Michael J.

    2010-03-01

    A religious perspective on life shapes how and what those with such a perspective learn in science; for some students a religious perspective can hinder learning in science. For such reasons Staver's article is to be welcomed as it proposes a new way of resolving the widely perceived discord between science and religion. Staver notes that Western thinking has traditionally postulated the existence and comprehensibility of a world that is external to and independent of human consciousness. This has led to a conception of truth, truth as correspondence, in which our knowledge corresponds to the facts in this external world. Staver rejects such a conception, preferring the conception of truth as coherence in which the links are between and among independent knowledge claims themselves rather than between a knowledge claim and reality. Staver then proposes constructivism as a vehicle potentially capable of resolving the tension between religion and science. My contention is that the resolution between science and religion that Staver proposes comes at too great a cost—both to science and to religion. Instead I defend a different version of constructivism where humans are seen as capable of generating models of reality that do provide richer and more meaningful understandings of reality, over time and with respect both to science and to religion. I argue that scientific knowledge is a subset of religious knowledge and explore the implications of this for science education in general and when teaching about evolution in particular.

  2. Informal science education at Science City

    Science.gov (United States)

    French, April Nicole

    The presentation of chemistry within informal learning environments, specifically science museums and science centers is very sparse. This work examines learning in Kansas City's Science City's Astronaut Training Center in order to identify specific behaviors associated with visitors' perception of learning and their attitudes toward space and science to develop an effective chemistry exhibit. Grounded in social-constructivism and the Contextual Model of Learning, this work approaches learning in informal environments as resulting from social interactions constructed over time from interaction between visitors. Visitors to the Astronaut Training Center were surveyed both during their visit and a year after the visit to establish their perceptions of behavior within the exhibit and attitudes toward space and science. Observations of visitor behavior and a survey of the Science City staff were used to corroborate visitor responses. Eighty-six percent of visitors to Science City indicated they had learned from their experiences in the Astronaut Training Center. No correlation was found between this perception of learning and visitor's interactions with exhibit stations. Visitor attitudes were generally positive toward learning in informal settings and space science as it was presented in the exhibit. Visitors also felt positively toward using video game technology as learning tools. This opens opportunities to developing chemistry exhibits using video technology to lessen the waste stream produced by a full scale chemistry exhibit.

    The biomedical sciences have experienced an explosion of data which promises to overwhelm many current practitioners. Without easy access to data science training resources, biomedical researchers may find themselves unable to wrangle their own datasets. In 2014, to address the challenges posed such a data onslaught, the National Institutes of Health (NIH) launched the Big Data to Knowledge (BD2K) initiative. To this end, the BD2K Training Coordinating Center (TCC; bigdatau.org) was funded to facilitate both in-person and online learning, and open up the concepts of data science to the widest possible audience. Here, we describe the activities of the BD2K TCC and its focus on the construction of the Educational Resource Discovery Index (ERuDIte), which identifies, collects, describes, and organizes online data science materials from BD2K awardees, open online courses, and videos from scientific lectures and tutorials. ERuDIte now indexes over 9,500 resources. Given the richness of online training materials and the constant evolution of biomedical data science, computational methods applying information retrieval, natural language processing, and machine learning techniques are required - in effect, using data science to inform training in data science.

  20. History of science and American science policy.

    Science.gov (United States)

    Wang, Zuoyue; Oreskes, Naomi

    2008-06-01

    Historians of science have participated actively in debates over American science policy in the post-World War II period in a variety of ways, but their impact has been more to elucidate general concepts than to effect specific policy changes. Personal experiences, in the case of the debate over global warming, have demonstrated both the value and the limits of such involvement for the making of public policy. To be effective, historians of science need to strive for clarity in public expression, to accept the importance of engaging with the public at all levels and through diverse media, and, above all, to recognize that the nature of such debates will make normal scholarly nuance hard to achieve. Moreover, in the current political climate, historians may be surprised to find themselves defending sciences, when the usual stance of historians is to be critical.

    How is science represented by the media? Who defines what counts as a risk, threat or hazard, and why? In what ways do media images of science shape public perceptions? What can cultural and media studies tell us about current scientific controversies? "Media, Risk and Science" is an exciting exploration into an array of important issues, providing a much needed framework for understanding key debates on how the media represent science and risk. In a highly effective way, Stuart Allan weaves together insights from multiple strands of research across diverse disciplines. Among the themes he examines are: the role of science in science fiction, such as "Star Trek"; the problem of 'pseudo-science' in "The X-Files"; and how science is displayed in science museums. Science journalism receives particular attention, with the processes by which science is made 'newsworthy' unravelled for careful scrutiny. The book also includes individual chapters devoted to how the media portray environmental risks, HIV-AIDS, food s...

    Schuhart, Arthur L.

    This is a two-part dissertation. The primary part is the text of a science-based composition rhetoric and reader called The Science Writing Tool. This textbook has seven chapters dealing with topics in Science Rhetoric. Each chapter includes a variety of examples of science writing, discussion questions, writing assignments, and instructional resources. The purpose of this text is to introduce lower-division college science majors to the role that rhetoric and communication plays in the conduct of Science, and how these skills contribute to a successful career in Science. The text is designed as a "tool kit," for use by an instructor constructing a science-based composition course or a writing-intensive Science course. The second part of this part of this dissertation reports on student reactions to draft portions of The Science Writing Tool text. In this report, students of English Composition II at Northern Virginia Community College-Annandale were surveyed about their attitudes toward course materials and topics included. The findings were used to revise and expand The Science Writing Tool.

    2015-01-01

    In a career that included tenures as president of Stony Brook University, director of Brookhaven National Laboratory, and science advisor to President George W. Bush, John Marburger (1941 2011) found himself on the front line of battles that pulled science ever deeper into the political arena. From nuclear power to global warming and stem cell research, science controversies, he discovered, are never just about science. Science Policy Up Close" presents Marburger s reflections on the challenges science administrators face in the twenty-first century. In each phase of public service Marburger came into contact with a new dimension of science policy. The Shoreham Commission exposed him to the problem of handling a volatile public controversy over nuclear power. The Superconducting Super Collider episode gave him insights into the collision between government requirements and scientists expectations and feelings of entitlement. The Directorship of Brookhaven taught him how to talk to the public about the risks ...

    This paper presents a categorisation of science game formats in relation to the educational possibilities or limitations they offer in science education. This includes discussion of new types of science game formats and gamification of science. Teaching with the use of games and simulations...... in science education dates back to the 1970s and early 80s were the potentials of games and simulations was discussed extensively as the new teaching tool ( Ellington et al. , 1981). In the early 90s the first ITC -based games for exploration of science and technical subjects was developed (Egenfeldt......-Nielsen, 2005). After the turn of the millennium, there has been an increasing awareness both on potentials in using commercial computer games in science education, and on developing so serious games for scientific subjects such as chemistry, physics and biology (Squire & Klopfer, 2007; Shaffer, 2006; Magnussen...

    2015-04-01

    I was a strong proponent of ``science diplomacy'' when I became Science and Technology Adviser to the Secretary of State in 2011. I thought I knew a lot about the subject after being engaged for four decades on international S&T policy issues and having had distinguished scientists as mentors who spent much of their time using science as a tool for building better relations between countries and working to make the world more peaceful, prosperous, and secure. I learned a lot from my three years inside the State Department, including great appreciation and respect for the real diplomats who work to defuse conflicts and avoid wars. But I also learned a lot about science diplomacy, both using science to advance diplomacy and diplomacy to advance science. My talk will focus on the five big things that I learned, and from that the one thing where I am focusing my energies to try to make a difference now that I am a private citizen again.

  13. Causal reasoning and models of cognitive tasks for naval nuclear power plant operators; Raisonnement causal et modelisation de l`activite cognitive d`operateurs de chaufferie nucleaire navale

    Salazar-Ferrer, P.

    1995-06-01

    In complex industrial process control, causal reasoning appears as a major component in operators` cognitive tasks. It is tightly linked to diagnosis, prediction of normal and failure states, and explanation. This work provides a detailed review of literature in causal reasoning. A synthesis is proposed as a model of causal reasoning in process control. This model integrates distinct approaches in Cognitive Science: especially qualitative physics, Bayesian networks, knowledge-based systems, and cognitive psychology. Our model defines a framework for the analysis of causal human errors in simulated naval nuclear power plant fault management. Through the methodological framework of critical incident analysis we define a classification of errors and difficulties linked to causal reasoning. This classification is based on shallow characteristics of causal reasoning. As an origin of these errors, more elementary component activities in causal reasoning are identified. The applications cover the field of functional specification for man-machine interfaces, operators support systems design as well as nuclear safety. In addition of this study, we integrate the model of causal reasoning in a model of cognitive task in process control. (authors). 106 refs., 49 figs., 8 tabs.

    As part of a program to increase learning and engagement in science classes 124 Victorian schools are trialing a best practice teaching model. The Science in Schools Research Project is a DEET funded project under the Science in Schools Strategy, developed in response to recent research and policy decisions at national and state levels through which literacy, numeracy and science have been identified as key priorities for learning. This major science research project aims to identify, develop and trial best practice in Science teaching and learning. The Department will then be able to provide clear advice to Victoria's schools that can be adopted and sustained to: * enhance teaching and learning of Science * enhance student learning outcomes in Science at all year levels * increase student access to, and participation in Science learning from Prep through to Year 10, and hence in the VCE as well. The nature of the SiS program will be detailed with specific reference to the innovative programs in solar model cars, robotics and environmental science developed at Forest Hill College in response to this project.

    (Abstract only) New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth was mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing, scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1-5, following the AAVSO/AAS meetings. World Science Festival was founded by Dr. Brian Greene, Columbia University, and is operated through the World Science Foundation. The Festival is "saturation science" all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in "science" venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend from hard science, with lectures like those by us astronomers, to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee. While almost all events are on Manhattan, effort has been made to geographically disperse them, even to the outer boroughs. The grand finale of World Science Festival is a street fair in Washington Square. Science centers in booths, tents, and pavilions highlight their work. In past years this fair drew 100,000 to 150,000 visitors. The entire Festival attracts about a quarter-million attendees. NYSkies is a proud participant at the Washington Square fair. It interprets the "Earth to the Universe" display, debuting during IYA-2009. Attendance at "Earth..." on just the day of the fair plausibly is half of all visitors in America. The presentation shows the scale and scope of World Science Festival, its relation to the City, and how our astronomers work with it.

  18. Science as theater, theater as science

    2002-04-01

    Beginning with Bertold Brecht's "Galileo" in 1942 and Friedrich Dürrenmatt's "The Physicists" in 1962, physics and other sciences have served a number of dramatists as backdrops for the exposition of existential problems, as well as the provision of entertainment. Michael Frayn's 1998 play "Copenhagen" broke new ground by giving a central role to the presentation of scientific substance and ideas and to the examination of recent controversial and emotionally charged events in the history of science and of the "real world". A rash of "science plays" erupted. How should we physicists react to this development? Surely, it can be argued, any exposure of science to the public is better than none and will help break down the barriers between the "two cultures". But what if the science or the scientists are badly misrepresented or the play is a weapon to strip science of its legitimacy and its claims to reality and truth? After reviewing a half dozen of the new plays, I conclude that "Copenhagen", though flawed, is not only the best of show, but a positive, even admirable endeavor. The contributions of Bohr, Heisenberg, Born, Schrödinger, and other scientists and their interactions in the golden years of the creation of quantum mechanics are accurately and thrillingly rendered. There may be no better non-technical exposition of complementarity and the uncertainty principle than the one that Frayn puts into the mouths of Bohr and Heisenberg. The treatment of the history of the atomic bomb and Heisenberg's role in Germany's failure to achieve a bomb is another matter. Frayn can also be criticized for applying uncertainly and complementarity to the macroscopic world and, in particular, to human interactions, thereby giving some aid and comfort to the post-modernists. These reservations aside, Copenhagen is a beautiful contribution to the appreciation of science.

    Full Text Available The so-called omnipotence of modern science and technology rests on fundamental convictions and views regarding their basic nature. The mythical claims as to the demonic or magical role played by science in society are strengthened on the one hand by the scientists, and on the other hand they Find an easy access to a "lay" public. I he belief in the omnipotence of science leads to a belief in progress which, in the context of the modern science and technology which have been “freed of values”, is endowed with the Role of saviour in a world devoid of mysticism. For the practice of academic and intellectual stewardship in the allocation of a legitimate but limited role to science, one of the primary pre-requisites is the demythologizing of the over-extended expectations cherished of science as an idol of progress.

  1. Science, expertise, and democracy.

    Weinberg, Justin; Elliott, Kevin C

    2012-06-01

    The combination of government's significant involvement in science, science's significant effects on the public, and public ignorance (of both politics and science) raise important challenges for reconciling scientific expertise with democratic governance. Nevertheless, there have recently been a variety of encouraging efforts to make scientific activity more responsive to social values and to develop citizens' capacity to engage in more effective democratic governance of science. This essay introduces a special issue of the Kennedy Institute of Ethics Journal, "Science, Expertise, and Democracy," consisting of five papers that developed from the inaugural Three Rivers Philosophy conference held at the University of South Carolina in April 2011. The pieces range from a general analysis of the in-principle compatibility of scientific expertise and democracy to much more concrete studies of the intersection between scientific practices and democratic values in areas such as weight-of-evidence analysis, climate science, and studies of locally undesirable land uses.

Science developed after Galileo and Descartes aims at universal truth but was founded on the notion of the Christian ...

  11. NEWS: Why choose science?

    2000-05-01

    National concerns over the uptake of science subjects and an analysis of how school science departments together with careers programmes influence students' subject choices feature in a recent report from the UK's National Institute for Careers Education and Counselling. It points out that decisions on science subjects are taken very early in pupils' education, often well before the implications of those choices can be clearly understood. If pupils are to be encouraged to keep science options open, then both science teachers and careers advisers have important roles to play. Physics is in fact singled out in the report's recommendations as in need of special attention, due to its perceived difficulty both within the double-award science course and also at A-level. The lack of qualified teachers in physics is noted as a problem for schools and the many initiatives to address these issues should be encouraged according to the report, but within an overall high-profile and well funded national strategy for developing science education in schools. The report also notes that science teachers do not feel able to keep up with career information, whilst few careers advisers have a science background and have little opportunity to build up their knowledge of science syllabuses or of science and engineering careers. More contact between both types of specialist is naturally advocated. Copies of the full report, Choosing Science at 16 by Mary Munro and David Elsom, are available from NICEC, Sheraton House, Castle Park, Cambridge CB3 0AX on receipt of an A4 stamped (70p) addressed envelope.

    The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the US Department of Energy Office of Science, the single largest supporter of basic research in the physical sciences in the United States. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 20 years. In April 2010 ESnet and the Office of Biological and Environmental Research, of the DOE Office of Science, organized a workshop to characterize the networking requirements of the science programs funded by BER. The requirements identified at the workshop are summarized and described in more detail in the case studies and the Findings section. A number of common themes emerged from the case studies and workshop discussions. One is that BER science, like many other disciplines, is becoming more and more distributed and collaborative in nature. Another common theme is that data set sizes are exploding. Climate Science in particular is on the verge of needing to manage exabytes of data, and Genomics is on the verge of a huge paradigm shift in the number of sites with sequencers and the amount of sequencer data being generated.

    An analyses study focusing on scientific reasoning literacy was conducted to strengthen the stressing on assessment in science by combining the important of the nature of science and assessment as references, higher order thinking and scientific skills in assessing science learning as well. Having background in developing science process skills test items, inquiry in its many form, scientific and STEM literacy, it is believed that inquiry based learning should first be implemented among science educators and science learners before STEM education can successfully be developed among science teachers, prospective teachers, and students at all levels. After studying thoroughly a number of science researchers through their works, a model of scientific reasoning was proposed, and also simple rubrics and some examples of the test items were introduced in this article. As it is only the beginning, further studies will still be needed in the future with the involvement of prospective science teachers who have interests in assessment, either on authentic assessment or in test items development. In balance usage of alternative assessment rubrics, as well as valid and reliable test items (standard) will be needed in accelerating STEM education in Indonesia.

While MGIMO-University is celebrating its 70th anniversary the Department of Political Sciences turns 15. Despite the fact that political analyst is a relatively new profession in Russia, it acquired a legal standing only in the 1990s, the political science school at MGIMO-University is almost as old as the university itself. Unlike many other universities, focused on the training teachers of political science or campaign managers MGIMO-University has developed its own unique political science school of "full cycle", where students grow into political sciences from a zero level up to the highest qualifications as teachers and researchers, and campaign managers, consultants and practitioners. The uniqueness of the school of political science at MGIMO-University allows its institutional incarnation -the Department of Political Science - to offer prospective studentsa training in a wide range of popular specialties and specializations, while ensuring a deep theoretical and practical basis of the training. Studying at MGIMO-University traditionally includes enhanced linguistic component (at least two foreign languages. For students of international relations and political science learning foreign languages is particularly important.It allows not only to communicate, but also to produce expertise and knowledge in foreign languages.

  5. Theoretical computer science and the natural sciences

    Marchal, Bruno

    2005-12-01

    I present some fundamental theorems in computer science and illustrate their relevance in Biology and Physics. I do not assume prerequisites in mathematics or computer science beyond the set N of natural numbers, functions from N to N, the use of some notational conveniences to describe functions, and at some point, a minimal amount of linear algebra and logic. I start with Cantor's transcendental proof by diagonalization of the non enumerability of the collection of functions from natural numbers to the natural numbers. I explain why this proof is not entirely convincing and show how, by restricting the notion of function in terms of discrete well defined processes, we are led to the non algorithmic enumerability of the computable functions, but also-through Church's thesis-to the algorithmic enumerability of partial computable functions. Such a notion of function constitutes, with respect to our purpose, a crucial generalization of that concept. This will make easy to justify deep and astonishing (counter-intuitive) incompleteness results about computers and similar machines. The modified Cantor diagonalization will provide a theory of concrete self-reference and I illustrate it by pointing toward an elementary theory of self-reproduction-in the Amoeba's way-and cellular self-regeneration-in the flatworm Planaria's way. To make it easier, I introduce a very simple and powerful formal system known as the Schoenfinkel-Curry combinators. I will use the combinators to illustrate in a more concrete way the notion introduced above. The combinators, thanks to their low-level fine grained design, will also make it possible to make a rough but hopefully illuminating description of the main lessons gained by the careful observation of nature, and to describe some new relations, which should exist between computer science, the science of life and the science of inert matter, once some philosophical, if not theological, hypotheses are made in the cognitive sciences.

    Sustainability is the theme of our time and also the grandest challenge to humanity. Since the 1970s, the term, sustainable development, has frequently appeared in the scientific literature, governmental documents, media promotions for public goods, and commercial advertisements. However, the science that provides the theoretical foundation and practical guidance for sustainable development--sustainability science--only began to emerge in the beginning of the 21st century. Nevertheless, the field has rapidly developed in depth and expanded in scope during the past decade, with its core concepts and research methods coalescing. China, as the most populous country in the world and home to the philosophical root of sustainability science-the unity of man and nature, is obligated to take upon the challenge of our time, to facilitate global sustainability while pursuing the Chinese Dream, and to play a leading role in the development of sustainability science. Toward this grandiose goal, this paper presents the first Chinese introduction to sustainability science, which discusses its basic concepts, research questions, and future directions. Sustainability science is the study of the dynamic relationship between humans and the environment, particularly focusing on the vulnerability, robustness, resilience, and stability of the coupled human-environment system. It is a transdisciplinary science that integrates natural sciences with humanities and social sciences. It hinges on the environment-economy-society nexus, and merges basic and applied research. The key components of sustainability often change with time, place, and culture, and thus sustainability science needs to emphasize multi-scale studies in space and time, with emphasis on landscapes and regions over a horizon of 50 to 100 years. It needs to focus on the relationship between ecosystem services and human well-being, as influenced by biodiversity and ecosystem processes as well as climate change, land use

    In 1994, the Clinton Administration issued a report, 'Science in the National Interest', which identified new national science goals. Two of the five goals are related to science communications: produce the finest scientists and engineers for the 21st century, and raise scientific and technological literacy of all Americans. In addition to the guidance and goals set forth by the Administration, NASA has been mandated by Congress under the 1958 Space Act to 'provide for the widest practicable and appropriate dissemination concerning its activities and the results thereof'. In addition to addressing eight Goals and Plans which resulted from a January 1994 meeting between NASA and members of the broader scientific, education, and communications community on the Public Communication of NASA's Science, the Science Communications Working Group (SCWG) took a comprehensive look at the way the Agency communicates its science to ensure that any changes the Agency made were long-term improvements. The SCWG developed a Science Communications Strategy for NASA and a plan to implement the Strategy. This report outlines a strategy from which effective science communications programs can be developed and implemented across the agency. Guiding principles and strategic themes for the strategy are provided, with numerous recommendations for improvement discussed within the respective themes of leadership, coordination, integration, participation, leveraging, and evaluation.

  1. What is Science?

    International Nuclear Information System (INIS)

    Quinn, H.

    2009-01-01

    Helen Quinn is a theoretical particle physicist at SLAC. Throughout her career, she has been passionately involved in science education and public understanding of science. In talking about science, whether to the public or to students, we scientists often assume that they share with us a common idea of science. In my experience that is often not the case. To oversimplify, scientists think of science both as a process for discovering properties of nature, and as the resulting body of knowledge, whereas most people seem to think of science, or perhaps scientists, as an authority that provides some information--just one more story among the many that they use to help make sense of their world. Can we close that gap in understanding? Middle school teachers typically spend a day or so teaching something called the scientific method, but the process by which scientific ideas are developed and tested is messier and much more interesting than that typical capsule description. Some remarkable features of the process are seldom stressed in teaching science, nor are they addressed in explaining any one piece of science to the public. My goal in this column is to provide some ideas for closing that gap in understanding, and to encourage scientists and teachers to communicate about the process as they discuss scientific work

    For roughly the last half century, chemistry has perhaps been the most disparaged of the sciences.

    2002-07-01

    Science is entering an alliance with the economy that will speed the effect of innovation through society. Despite the slowdown of the 'new economy', a cascade paradigm of innovation appears key to increasing the rate of economic growth. Yet for science to continue to thrive and make this contribution to innovation, it must traverse at least three key crossroads. First, while life sciences have built a strong advocacy model to secure growing federal research funding, the physical sciences (including mathematics and engineering) have not and must now do so to thrive. Second, the drop in the numbers of physical scientists and engineers must be reversed if we are to have the talent to maintain a strong trend of scientific advance. Third, although science advances are increasingly interdisciplinary and occurring in the space between the historic science stovepipes, the organization of federal science support is largely unchanged since the beginning of the cold war. While a decentralized model has value, we must also consider new approaches that encourage deeper cooperation across science sectors and agencies.

  12. Science and Art

    Science.gov (United States)

    Moore, John W.

    2001-10-01

    Science and art diverge in that art usually represents a single individual's conception and viewpoint, even when many others are involved in bringing a work to fruition, whereas science progresses by extending consensus among those knowledgeable in a field. Art usually communicates at an emotional level. It values individual expression and impact on the emotions at the expense of objectivity. Science, especially in its archival record, values objectivity and reproducibility and does not express the imagination and joy of discovery inherent in its practice. This is too bad, because it does not give a realistic picture of how science is really done and because individuality and emotion are inherently more interesting than consensus. Leaving out the personal, emotional side can make science seem boring and pedestrian, when exactly the opposite is true. In teaching science we need to remember that communication always benefits from imagination and esthetic sense. If we present science artistically and imaginatively, as well as objectively and precisely, students will develop a more complete understanding of what science and scientists are about--one that is likely to capture their imaginations, emotions, and best efforts.

    considering the particular situation where regions of the representative volume element have ill-defined mechanical properties. In the linear elastic case, new bounds for the effective behaviour are derived by marrying the structural analysis and a variational approach. This last work opens on important prospects for further works: more tightened bounds, nonlinear behaviours,... Considering homogenisation methods, further works are precisely defined, in particular for polycrystalline materials. In that situation, the field of investigation widens clearly (Fatigue, Large strains,...) thanks to the internal variables formulation proposed. Lastly, the simulation of irradiation effects constitutes the third topic of interest for the years to come, the general objective being to better predict the effects of the swelling strains induced by irradiation on the behaviour of structural components under service.

    The activities presented in this paper, which are addressed to elementary school, are focused on the pioneering work of the Portuguese King Carlos I in oceanography and involve the exploration of the exhibits belonging to two different science museums, the Aquarium Vasco da Gama and the Maritime Museum. Students were asked to study fish adaptations to deep sea, through the exploration of a fictional story, based on historical data and based on the work of the King that served as a guiding script for all the subsequent tasks. In both museums, students had access to: historical collections of organisms, oceanographic biological sampling instruments, fish gears and ships. They could also observe the characteristics and adaptations of diverse fish species characteristic of deep sea. The present study aimed to analyse the impact of these activities on students' scientific knowledge, on their understanding of the nature of science and on the development of transversal skills. All students considered the project very popular. The results obtained suggest that the activity promoted not only the understanding of scientific concepts, but also stimulated the development of knowledge about science itself and the construction of scientific knowledge, stressing the relevance of creating activities informed by the history of science. As a final remark we suggest that the partnership between elementary schools and museums should be seen as an educational project, in which the teacher has to assume a key mediating role between the school and the museums.

Furthermore, also cause friction between computer scientists from different branches. Because of how they are structured, these sciences programs are criticized for not offer an adequate methodological training, or a deep understanding of different research traditions. To collaborate on a solution, some have decided to include in their curricula courses that enable students to gain awareness about epistemology and methodological issues in Computer Science, as well as give meaning to the practice of computer scientists. In this article the needs and objectives of the courses on the philosophy of Computer Science are analyzed, and its structure and management are explained.

    2016-12-01

    Effective science communication can open doors, accelerate your career and even make you a better scientist. Part of being an effective and productive scientist means being an effective science communicator. The scientist must communicate their work in talks, posters, peer-reviewed papers, internal reports, proposals as well as to the broader public (including law makers). Despite the importance of communication, it has traditionally not been part of our core training as scientists. Today's science students are beginning to have more opportunities to formally develop their science communication skills. Fortunately, new and even more established scientists have a range of tools and resources at their disposal. In this presentation, we will share some of these resources, share our own experiences utilizing them, and provide some practical tools to improve your own science communication skills.

Is it like corporate responsibility an add-on to the main product: we produce knowledge and scientific solutions, but we also care for the environment, for sustainability, for fair-trade and so on? Or doesn’t social responsibility add to science at all...... solving problems and thus creating a base for science in its strategic mode, in its interplay-with-society mode.

    Over the last 10-15 years, significant advances have been made in information management, there are an increasing number of individuals entering the field of information management as it applies to Geoscience and Remote Sensing data, and the field of informatics has come to its own. Informatics is the science and technology of applying computers and computational methods to the systematic analysis, management, interchange, and representation of science data, information, and knowledge. Informatics also includes the use of computers and computational methods to support decision making and applications. Earth Science Informatics (ESI, a.k.a. geoinformatics) is the application of informatics in the Earth science domain. ESI is a rapidly developing discipline integrating computer science, information science, and Earth science. Major national and international research and infrastructure projects in ESI have been carried out or are on-going. Notable among these are: the Global Earth Observation System of Systems (GEOSS), the European Commissions INSPIRE, the U.S. NSDI and Geospatial One-Stop, the NASA EOSDIS, and the NSF DataONE, EarthCube and Cyberinfrastructure for Geoinformatics. More than 18 departments and agencies in the U.S. federal government have been active in Earth science informatics. All major space agencies in the world, have been involved in ESI research and application activities. In the United States, the Federation of Earth Science Information Partners (ESIP), whose membership includes over 180 organizations (government, academic and commercial) dedicated to managing, delivering and applying Earth science data, has been working on many ESI topics since 1998. The Committee on Earth Observation Satellites (CEOS)s Working Group on Information Systems and Services (WGISS) has been actively coordinating the ESI activities among the space agencies.The talk will present an overview of current efforts in ESI, the role members of IEEE GRSS play, and discuss

    In April 1994 the National Research Council received a request from NASA that the NRC's Space Studies Board provide guidance on questions relating to the management of NASA's programs in the space sciences. The issues raised in the request closely reflect questions posed in the agency's fiscal year 1994 Senate appropriations report. These questions included the following: Should all the NASA space science programs be gathered into a 'National Institute for Space Science'? What other organizational changes might be made to improve the coordination and oversight of NASA space science programs? What processes should be used for establishing interdisciplinary science priorities based on scientific merit and other criteria, while ensuring opportunities for newer fields and disciplines to emerge? And what steps could be taken to improve utilization of advanced technologies in future space scienc missions? This report details the findings of the Committee on the Future of Space Science (FOSS) and its three task groups: the Task Group on Alternative Organizations, Task Group on Research Prioritization, and the Task Group on Technology.

  1. Value of Fundamental Science

    Science.gov (United States)

    Burov, Alexey

    Fundamental science is a hard, long-term human adventure that has required high devotion and social support, especially significant in our epoch of Mega-science. The measure of this devotion and this support expresses the real value of the fundamental science in public opinion. Why does fundamental science have value? What determines its strength and what endangers it? The dominant answer is that the value of science arises out of curiosity and is supported by the technological progress. Is this really a good, astute answer? When trying to attract public support, we talk about the ``mystery of the universe''. Why do these words sound so attractive? What is implied by and what is incompatible with them? More than two centuries ago, Immanuel Kant asserted an inseparable entanglement between ethics and metaphysics. Thus, we may ask: which metaphysics supports the value of scientific cognition, and which does not? Should we continue to neglect the dependence of value of pure science on metaphysics? If not, how can this issue be addressed in the public outreach? Is the public alienated by one or another message coming from the face of science? What does it mean to be politically correct in this sort of discussion?

    Full Text Available At the time when the journal Sustainability [1] was launched, as a chemist and a scientist, I started to believe that social sciences may be more important to make humans sustainable. The broad journal title Social Sciences presents the opportunity for all social science scholars to have integrated consideration regarding the sustainability of humanity, because I am sure that science and technology alone cannot help. Science and technology may have in fact been contributing to accelerate the depletion of nonrenewable natural resources and putting human sustainability at risk since the industrial revolution about 150 years ago. I hope all intellectuals studying anthropology, archaeology, administration, communication, criminology, economics, education, government, linguistics, international relations, politics, sociology and, in some contexts, geography, history, law, and psychology publish with us to seek a solution to sustain humanity. Sustainability itself will also be a main topic of the journal Social Sciences. In addition to this integrated forum for social sciences, more topic specific journals, such as the already publishing Societies [2], will be launched. [...

    During the opening ceremony, the audience was dazzled by a juggling show involving dramatic light effects. They also took away with them a teacher's sheet explaining some of the scientific concepts involved in juggling. Science teachers can sometimes be quite humorous when it comes to explaining serious matters, as those who took part in the 'Science on Stage' festival held at CERN from 21 to 25 November were able to see for themselves. The 500 or so participants from 27 different countries, mostly science teachers but also some university lecturers, science outreach specialists and students, had the opportunity to share their experience of the teaching of science. They also attended presentations and shows, took part in workshops and visited a fair with stands offering ideas on how to make school science lessons more appealing. The festival, organised by the EIROforum (a partnership between CERN, EFDA, ESA, ESO, EMBL, ESRF and ILL), marked the end of two years of projects for the promotion of science in vir...

  4. Style in science communication.

    Science.gov (United States)

    Bucchi, Massimiano

    2013-11-01

    There is little doubt that during the past few decades science communication efforts aimed at non-expert audiences have increased in quantity and intensity on a global scale. Public engagement and outreach activities have now become a routine - when not a prominent - feature for several research institutions in Europe. However, it would be difficult for both scholars and those involved in science communication to agree on the impact of these activities, on the long-term implications of the 'science communication movement' and on the indicators we should develop and employ in order to assess impact. The paper argues that quality is a relevant issue and challenge for contemporary science communication. Style is relevant to addressing that challenge, insofar as it relates to discussions about how to strengthen the quality of science communication, suggesting a different perspective other than the traditional normative/prescriptive framework. The notion of style also fruitfully connects the debate on science communication with a rich tradition of studies in the history and sociology of science.

  5. The Data Science Landscape

    Science.gov (United States)

    Mentzel, C.

    2017-12-01

    Modern scientific data continue to increase in volume, variety, and velocity, and though the hype of big data has subsided, its usefulness for scientific discovery has only just begun. Harnessing these data for new insights, more efficient decision making, and other mission critical uses requires a combination of skills and expertise, often labeled data science. Data science can be thought of as a combination of statistics, computation and the domain from which the data relate, and so is a true interdisciplinary pursuit. Though it has reaped large benefits in companies able to afford the high cost of the severely limited talent pool, it suffers from lack of support in mission driven organizations. Not purely in any one historical field, data science is proving difficult to find a home in traditional university academic departments and other research organizations. The landscape of data science efforts, from academia, industry and government, can be characterized as nascent, enthusiastic, uneven, and highly competitive. Part of the challenge in documenting these trends is the lack of agreement about what data science is, and who is a data scientist. Defining these terms too closely and too early runs the risk of cutting off a tremendous amount of productive creativity, but waiting too long leaves many people without a sustainable career, and many organizations without the necessary skills to gain value from their data. This talk will explore the landscape of data science efforts in the US, including how organizations are building and sustaining data science teams.

  6. Science, Society and Policy

    White, K. S.; Teich, A. H.

    2010-12-01

    Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

    The book examines the emerging approach of using qualitative methods, such as interviews and field observations, in the philosophy of science. Qualitative methods are gaining popularity among philosophers of science as more and more scholars are resorting to empirical work in their study...... of scientific practices. At the same time, the results produced through empirical work are quite different from those gained through the kind of introspective conceptual analysis more typical of philosophy. This volume explores the benefits and challenges of an empirical philosophy of science and addresses...

    It is a pity that the correspondents to Physics World (April p18, May p22) seem to think that all change to school science is retrogressive, flawed and fundamentally a mistake. I wish that they would take the critical lens that they apply to other school science courses to the ones that they seem to view through rose-tinted spectacles. The overwhelming body of evidence is that O-level and IGCSE type courses present physics as an established body of unequivocal and unquestioned knowledge that must be learned and reproduced for the appropriate examination, the predominant effect of which is to alienate many young people from science forever.

  9. The Next Great Science

    Science.gov (United States)

    Hodges, K. V.

    2007-12-01

    Earth science --- when defined as the study of all biological, chemical, and physical processes that interact to define the behavior of the Earth system --- has direct societal relevance equal to or greater than that any other branch of science. However, "geology", "geoscience", and "Earth science" departments are contracting at many universities and even disappearing at some. This irony speaks volumes about the limitations of the traditional university structure that partitions educational and research programs into specific disciplines, each housed in its own department. Programs that transcend disciplinary boundaries are difficult to fit into the traditional structure and are thus highly vulnerable to threats such as chronic underfunding by university administrations, low enrollments in more advanced subjects, and being largely forgotten during capital campaigns. Dramatic improvements in this situation will require a different way of thinking about earth science programs by university administrations. As Earth scientists, our goal must not be to protect "traditional" geology departments, but rather to achieve a sustainable programmatic future for broader academic programs that focus on Earth evolution from past, present, and future perspectives. The first step toward meeting this goal must be to promote a more holistic definition of Earth science that includes modes of inquiry more commonly found in engineering and social science departments. We must think of Earth science as a meta-discipline that includes core components of physics, geology, chemistry, biology, and the emerging science of complexity. We must recognize that new technologies play an increasingly important role in our ability to monitor global environmental change, and thus our educational programs must include basic training in the modes of analysis employed by engineers as well as those employed by scientists. One of the most important lessons we can learn from the engineering community is the

  11. Science, conscience, consciousness.

    Science.gov (United States)

    Hennig, Boris

    2010-01-01

    Descartes' metaphysics lays the foundation for the special sciences, and the notion of consciousness ("conscientia") belongs to metaphysics rather than to psychology. I argue that as a metaphysical notion, "consciousness" refers to an epistemic version of moral conscience. As a consequence, the activity on which science is based turns out to be conscientious thought. The consciousness that makes science possible is a double awareness: the awareness of what one is thinking, of what one should be doing, and of the possibility of a gap between the two.

    Full Text Available In this critical assessment of the ‘museology of science’ I cherry-pick recent scholarship and practice to unpack the functions of science collections. Some practices (exhibition, engagement, study have already attracted considerable attention, others not yet (storage; but all tend to be considered separately as case studies from particular institutions and for particular disciplinary audiences. Juxtaposing different reasons to collect reveals both the tensions inherent in science collections and the opportunities these collections afford, especially around their materiality. This is why we have collected science, and why we should continue.

    2002-01-01

    From award-winning science writer John Gribbin, "Science: A History" is the enthralling story of the men and women who changed the way we see the world, and the turbulent times they lived in. From Galileo, tried by the Inquisition for his ideas, to Newton, who wrote his rivals out of the history books; from Marie Curie, forced to work apart from male students for fear she might excite them, to Louis Agassiz, who marched his colleagues up a mountain to prove that the ice ages had occurred. Filled with pioneers, visionaries, eccentrics and madmen, this is the history of science as it has never been told before.

  20. Learning Science: Some Insights from Cognitive Science

    Science.gov (United States)

    Matthews, P. S. C.

    Theories of teaching and learning, including those associated with constructivism, often make no overt reference to an underlying assumption that they make; that is, human cognition depends on domain-free, general-purpose processing by the brain. This assumption is shown to be incompatible with evidence from studies of children's early learning. Rather, cognition is modular in nature, and often domain-specific. Recognition of modularity requires a re-evaluation of some aspects of current accounts of learning science. Especially, children's ideas in science are sometimes triggered rather than learned. It is in the nature of triggered conceptual structures that they are not necessarily expressible in language, and that they may not be susceptible to change by later learning.

  10. Pseudoscience and science fiction

    CERN Document Server

    May, Andrew

    2017-01-01

    Aliens, flying saucers, ESP, the Bermuda Triangle, antigravity … are we talking about science fiction or pseudoscience? Sometimes it is difficult to tell the difference. Both pseudoscience and science fiction (SF) are creative endeavours that have little in common with academic science, beyond the superficial trappings of jargon and subject matter. The most obvious difference between the two is that pseudoscience is presented as fact, not fiction. Yet like SF, and unlike real science, pseudoscience is driven by a desire to please an audience – in this case, people who “want to believe”. This has led to significant cross-fertilization between the two disciplines. SF authors often draw on “real” pseudoscientific theories to add verisimilitude to their stories, while on other occasions pseudoscience takes its cue from SF – the symbiotic relationship between ufology and Hollywood being a prime example of this. This engagingly written, well researched and richly illustrated text explores a wide range...

    The birth and decline of disciplines are critical to science and society. How do scientific disciplines emerge? No quantitative model to date allows us to validate competing theories on the different roles of endogenous processes, such as social collaborations, and exogenous events, such as scientific discoveries. Here we propose an agent-based model in which the evolution of disciplines is guided mainly by social interactions among agents representing scientists. Disciplines emerge from splitting and merging of social communities in a collaboration network. We find that this social model can account for a number of stylized facts about the relationships between disciplines, scholars, and publications. These results provide strong quantitative support for the key role of social interactions in shaping the dynamics of science. While several ``science of science'' theories exist, this is the first account for the emergence of disciplines that is validated on the basis of empirical data.

    The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the U.S. Department of Energy (DOE) Office of Science (SC), the single largest supporter of basic research in the physical sciences in the United States. To support SC programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 20 years. In August 2011, ESnet and the Office of Nuclear Physics (NP), of the DOE SC, organized a workshop to characterize the networking requirements of the programs funded by NP. The requirements identified at the workshop are summarized in the Findings section, and are described in more detail in the body of the report.

    The post–World War II era was one of great triumph for American linguists—and yet linguistics is all but absent from the historical literature on postwar social science. This paper aims to illuminate this curious situation: to understand its provenance, evaluate its merits, and contextualize...... it broadly. I argue that the historiographic lacuna results from two factors: (1) the opt-out of linguists from the wider American social science community, and (2) historical-developmental and -orientational factors that stand linguistics apart from the social science mainstream. The resultant isolation...... of linguistics has led to a parallel isolation in the historical literature. Ultimately, this paper poses a pivotal and timely question: How is the postwar social science space construed within the existing historiographic framework, and how should it be construed in order to maximize understanding? I propose...

    This paper reviews the uneven history of the relationship between Anthropology and Cognitive Science over the past 30 years, from its promising beginnings, followed by a period of disaffection, on up to the current context, which may lay the groundwork for reconsidering what Anthropology and (the rest of) Cognitive Science have to offer each other. We think that this history has important lessons to teach and has implications for contemporary efforts to restore Anthropology to its proper place within Cognitive Science. The recent upsurge of interest in the ways that thought may shape and be shaped by action, gesture, cultural experience, and language sets the stage for, but so far has not fully accomplished, the inclusion of Anthropology as an equal partner.

    2016-02-01

    To monitor science motivation, 232 tenth graders of the college preparatory level ('Gymnasium') completed the Science Motivation Questionnaire II (SMQ-II). Additionally, personality data were collected using a 10-item version of the Big Five Inventory. A subsequent exploratory factor analysis based on the eigenvalue-greater-than-one criterion, extracted a loading pattern, which in principle, followed the SMQ-II frame. Two items were dropped due to inappropriate loadings. The remaining SMQ-II seems to provide a consistent scale matching the findings in literature. Nevertheless, also possible shortcomings of the scale are discussed. Data showed a higher perceived self-determination in girls which seems compensated by their lower self-efficacy beliefs leading to equality of females and males in overall science motivation scores. Additionally, the Big Five personality traits and science motivation components show little relationship.

    Concerning the future fast neutrons reactors, studied in the frame of the European Fast Reactor (E.F.R.) project, several innovations have been proposed particularly in the field of vapor generators. These vapor generators have the particularity to use two different exchange fluids which can react violently one with the other. The thermodynamic fluid or secondary fluid is water under high pressure (18.5 MPa) which comes under saturated in the inlet of the device, warms and vaporizes inside the nest of boiler-tubes. At the outlet, vapor is overheated. The primary fluid is a liquid metal (sodium for French reactors) which flows outside the nest of boiler-tubes in the opposite direction of the secondary fluid. Several vapor generators models have been carried out. Concerning the European Fast Reactor project, the tubes have a cross-section and are in ferritic steel. Inside the boiler-tubes, the water-vapor flow can be divided into three areas. The first one is the liquid monophasic rate. It ends by the start of the boiling which is nucleated in the shell. Downstream, the two-phase flow passes from a bubbles flow to an annular flow. The liquid is then on the form of shell film and on the form of droplets carried along by the vapor flux. The dryout of the annular film is the start of the third area where there is vapor forced convection. At the present time, there is still no thermohydraulic code in the conditions of the E.F.R. vapor generator. In order to have a reliable size tool, the members of the E.F.R. project have then decided to do a two-phase flow model and have experimented a mono tubular scale model called ``ATLAS`` which represents well the real component for size, fluids and running conditions. The aim of the present work is then, in the frame of this experimental program, to 1)qualify the heat exchange and friction laws which will be later introduced in the thermohydraulic codes of cross-sections vapor generators 2)characterize the dryout phenomenon 3)quantify the thermal disequilibrium between the phases in a vapor-droplets dispersed flow.

    The late astronomer Carl Sagan popularized the saying that "extraordinary claims require extraordinary evidence," in reference to reports of alien visitations. Generating low-cost commercial fusion power, isolating antimatter and tracing reverse-time causality aren't as far out there as UFOs, but a similar rule might well apply: Extraordinary science requires extraordinary effort. With that in mind, here's a progress report on three extraordinary science projects that have popped up in the news...

  3. Water, law, science

    Narasimhan, T. N.

    2008-01-01

    SummaryIn a world with water resources severely impacted by technology, science must actively contribute to water law. To this end, this paper is an earth scientist's attempt to comprehend essential elements of water law, and to examine their connections to science. Science and law share a common logical framework of starting with a priori prescribed tenets, and drawing consistent inferences. In science, observationally established physical laws constitute the tenets, while in law, they stem from social values. The foundations of modern water law in Europe and the New World were formulated nearly two thousand years ago by Roman jurists who were inspired by Greek philosophy of reason. Recognizing that vital natural elements such as water, air, and the sea were governed by immutable natural laws, they reasoned that these elements belonged to all humans, and therefore cannot be owned as private property. Legally, such public property was to be governed by jus gentium, the law of all people or the law of all nations. In contrast, jus civile or civil law governed private property. Remarkably, jus gentium continues to be relevant in our contemporary society in which science plays a pivotal role in exploiting vital resources common to all. This paper examines the historical roots of modern water law, follows their evolution through the centuries, and examines how the spirit of science inherent in jus gentium is profoundly influencing evolving water and environmental laws in Europe, the United States and elsewhere. In a technological world, scientific knowledge has to lie at the core of water law. Yet, science cannot formulate law. It is hoped that a philosophical understanding of the relationships between science and law will contribute to their constructively coming together in the service of society.

    2001-01-01

    Last year, the first Science Night attracted nearly 1500 people. Dipping into history for the space of one night? This is the idea of Geneva's Museum of the History of Science, which is organizing its second Science Night, on 7 and 8 July, on the history of science. The first such event, held last year, was a considerable success with almost 15 000 visitors. The second Science Night, to be held in the magnificent setting of the Perle du Lac Park in Geneva, promises to be a winner too. By making science retell its own history, this major event is intended to show how every scientific and technical breakthrough is the culmination of a long period of growth that began hundreds of years in the past. Dozens of activities and events are included in this programme of time travel: visitors can study the night sky through telescopes and see what Galileo first observed, and then go to see a play on the life of the Italian scientist. Another play, commissioned specially for the occasion, will honour Geneva botanist De ...

    2016-02-01

    I will provide an overview of the Next Generation Science Standards (NGSS) and demonstrate how scientists and educators can use these standards to strengthen and enhance their collaborations. The NGSS are rich in content and practice and provide all students with an internationally-benchmarked science education. Using these state-led standards to guide outreach efforts can help develop and sustain effective and mutually beneficial teacher-researcher partnerships. Aligning outreach with the three dimensions of the standards can help make research relevant for target audiences by intentionally addressing the science practices, cross-cutting concepts, and disciplinary core ideas of the K-12 science curriculum that drives instruction and assessment. Collaborations between researchers and educators that are based on this science framework are more sustainable because they address the needs of both scientists and educators. Educators are better able to utilize science content that aligns with their curriculum. Scientists who learn about the NGSS can better understand the frameworks under which educators work, which can lead to more extensive and focused outreach with teachers as partners. Based on this model, the International Ocean Discovery Program (IODP) develops its education materials in conjunction with scientists and educators to produce accurate, standards-aligned activities and curriculum-based interactions with researchers. I will highlight examples of IODP's current, successful teacher-researcher collaborations that are intentionally aligned with the NGSS.

    2012-09-01

    Such categories as applied science and pure science can be thought of as "ideological." They have been contested in the public sphere, exposing long-term intellectual commitments, assumptions, balances of power, and material interests. This group of essays explores the contest over applied science in Britain and the United States during the nineteenth century. The essays look at the concept in the context of a variety of neighbors, including pure science, technology, and art. They are closely related and connected to contemporary historiographic debate. Jennifer Alexander links the issues raised to a recent paper by Paul Forman. Paul Lucier and Graeme Gooday deal with the debates in the last quarter of the century in the United States and Britain, respectively. Robert Bud deals with the earlier part of the nineteenth century, with an eye specifically on the variety of concepts hybridized under the heading of "applied science." Eric Schatzberg looks at the erosion of the earlier concept of art. As a whole, the essays illuminate both long-term changes and nuanced debate and are themselves intended to provoke further reflection on science in the public sphere.

    The Smithsonian Institution's National Museum of Natural History in Washington D.C. is planning to show a film, "A Privileged Planet" that promotes creationism in the form of "intelligent design." The film is based on the book by Guillermo Gonzalez and Jay Wesley Richards, both affiliated with the Discovery Institute, which advocates teaching "intelligent design" as science in U.S. public schools. By associating with the Discovery Institute, the Smithsonian Institution will associate science with creationism and damage their credibility. The film is slated for airing on 23 June, unless the Smithsonian comes to its senses.Why is this important? Because the film promotes a long term strategy of the Discovery Institute (//www.discovery.org/csc/) to replace "materialistic science" with "intelligent design." The film fosters the idea that science should include the supernatural. This is unacceptable. AGU's position is clear, creationism is not science and AGU opposes all efforts to promote creationism as science, (The full text of the AGU position statement can be found at: //www.agu.org/sci_soc/policy/positions/evolution.shtml).

    Full text: The Australian Synchrotron Radiation Program, ASRP, has been set up as a major national research facility to provide facilities for scientists and technologists in physics, chemistry, biology and materials science who need access to synchrotron radiation. Australia has a strong tradition in crystallography and structure determination covering small molecule crystallography, biological and protein crystallography, diffraction science and materials science and several strong groups are working in x-ray optics, soft x-ray and vacuum ultra-violet physics. A number of groups whose primary interest is in the structure and dynamics of surfaces, catalysts, polymer and surfactant science and colloid science are hoping to use scattering methods and, if experience in Europe, Japan and USA can be taken as a guide, many of these groups will need third generation synchrotron access. To provide for this growing community, the Australian National Beamline at the Photon Factory, Tsukuba, Japan, has been established since 1990 through a generous collaboration with Japanese colleagues, the beamline equipment being largely produced in Australia. This will be supplemented in 1997 with access to the world's most powerful synchrotron x-ray source at the Advanced Photon Source, Argonne National Laboratory, USA. Some recent experiments in surface science using neutrons as well as x-rays from the Australian National Beamline will be used to illustrate one of the challenges that synchrotron x-rays may meet

    The Plasma Science Committee (PLSC) is a standing committee under the auspices of the Board on Physics and Astronomy, Commission on Physical Sciences, Mathematics, and Applications of the National Academy of Sciences--National Research Council. Plasma sciences represent a broad and diverse field. The PLSC has accepted the responsibility of monitoring the continuing development and assessing the general health of the field as whole. Although select advisory bodies have been created to address specific issues that affect plasma science, such as the Fusion Policy Advisory Committee (FPAC), the PLSC provides a focus for the plasma science community that is unique and essential. The membership of the PLSC is drawn from research laboratories in universities, industry, and government. Areas of expertise on the committee include accelerators and beams, space physics, astrophysics, computational physics and applied mathematics, fusion plasmas, fundamental experiments and theory, radiation sources, low temperature plasmas, and plasma-surface interactions. The PLSC is well prepared to respond to requests for studies on specific issues. This report discusses ion of the PLSC work

    In contrast to many other human endeavors, science pays little attention to its history. Fundamental scientific discoveries are often considered to be timeless and independent of how they were made. Science and the history of science are regarded as independent academic disciplines. Although most scientists are aware of great discoveries in their fields and their association with the names of individual scientists, few know the detailed stories behind the discoveries. Indeed, the history of scientific discovery is sometimes recorded only in informal accounts that may be inaccurate or biased for self-serving reasons. Scientific papers are generally written in a formulaic style that bears no relationship to the actual process of discovery. Here we examine why scientists should care more about the history of science. A better understanding of history can illuminate social influences on the scientific process, allow scientists to learn from previous errors, and provide a greater appreciation for the importance of serendipity in scientific discovery. Moreover, history can help to assign credit where it is due and call attention to evolving ethical standards in science. History can make science better.

  14. Science transfer for development

    International Nuclear Information System (INIS)

    Salam, A.

    1985-01-01

    Despite the recent realisation that science and technology are the sustenance and major hope for economic betterment, the third world, barring a few countries like Argentina, Brazil, China and India, has taken to science - as distinct from technology - as only a marginal activity. This is also true of the aid - giving agencies of the richer countries, of the agencies of the UN and also unfortunately of the scientific communities of the developed countries which might naturally be expected to be the Third World's foremost allies. Policy makers, prestigious commissions (like the Brandt Commission) as well as aid-givers, speak uniformly of problems of technology transfer to the developing countries as if that is all that is involved. Very few within the developing world appear to stress that for long term effectiveness, technology transfers must always be accompanied by science transfers; that the science of today is the technology of tomorrow. Science transfer is effected by and to communities of scientists. Such communities (in developing countries) need building up to a critical size in their human resources and infrastructure. This building up calls for wise science policies, with long term commitment, generous patronage, self governance and free international contacts. Further, in our countries, the high level scientist must be allowed to play a role in nation building as an equal partner to the professional planner, the economist and the technologist. Few developing countries have promulgated such policies: few aid agencies have taken it as their mandate to encourage and help build up the scientific infrastructure. (author)

    This study examines science interests, efficacy, attitudes, and identity—referred to as affinities, in the context of an informal science outreach program for girls. A mixed methods design was used to explore girls' science affinities before, during, and after participation in a cohort-based summer science camp. Multivariate analysis of survey data revealed that girls' science affinities varied as a function of the joint relationship between family background and number of years in the program, with girls from more affluent families predicted to increase affinities over time and girls from lower income families to experience initial gains in affinities that diminish over time. Qualitative examination of girls' perspectives on gender and science efficacy, attitudes toward science, and elements of science identities revealed a complex interplay of gendered stereotypes of science and girls' personal desires to prove themselves knowledgeable and competent scientists. Implications for the best practice in fostering science engagement and identities in middle school-aged girls are discussed.

    Gooday, Graeme; Lynch, John M; Wilson, Kenneth G; Barsky, Constance K

    2008-06-01

    This essay argues that science education can gain from close engagement with the history of science both in the training of prospective vocational scientists and in educating the broader public about the nature of science. First it shows how historicizing science in the classroom can improve the pedagogical experience of science students and might even help them turn into more effective professional practitioners of science. Then it examines how historians of science can support the scientific education of the general public at a time when debates over "intelligent design" are raising major questions over the kind of science that ought to be available to children in their school curricula. It concludes by considering further work that might be undertaken to show how history of science could be of more general educational interest and utility, well beyond the closed academic domains in which historians of science typically operate.

  15. Planification de la maintenance d'un parc de turbines-alternateurs par programmation mathematique

    Science.gov (United States)

    Aoudjit, Hakim

    A growing number of Hydro-Quebec's hydro generators are at the end of their useful life and maintenance managers fear to face a number of overhauls exceeding what can be handled. Maintenance crews and budgets are limited and these withdrawals may take up to a full year and mobilize significant resources in addition to the loss of electricity production. In addition, increased export sales forecasts and severe production patterns are expected to speed up wear that can lead to halting many units at the same time. Currently, expert judgment is at the heart of withdrawals which rely primarily on periodic inspections and in-situ measurements and the results are sent to the maintenance planning team who coordinate all the withdrawals decisions. The degradations phenomena taking place is random in nature and the prediction capability of wear using only inspections is limited to short-term at best. A long term planning of major overhauls is sought by managers for the sake of justifying and rationalizing budgets and resources. The maintenance managers are able to provide a huge amount of data. Among them, is the hourly production of each unit for several years, the repairs history on each part of a unit as well as major withdrawals since the 1950's. In this research, we tackle the problem of long term maintenance planning for a fleet of 90 hydro generators at Hydro-Quebec over a 50 years planning horizon period. We lay a scientific and rational framework to support withdrawals decisions by using part of the available data and maintenance history while fulfilling a set of technical and economic constraints. We propose a planning approach based on a constrained optimization framework. We begin by decomposing and sorting hydro generator components to highlight the most influential parts. A failure rate model is developed to take into account the technical characteristics and unit utilization. Then, replacement and repair policies are evaluated for each of the components then strategies are derived for the whole unit. Traditional univariate policies such as the age replacement policy and the minimal repair policy are calculated. These policies are extended to build alternative bivariate maintenance policy as well as a repair strategy where the state of a component after a repair is rejuvenated by a constant coefficient. These templates form the basis for the calculation of objective function for the scheduling problem. On one hand, this issue is treated as a nonlinear problem where the objective is to minimize the average total maintenance cost per unit of time on an infinite horizon for the fleet with technical and economic constraints. A formulation is also proposed in the case of a finite time horizon. In the event of electricity production variation, and given that the usage profile is known, the influence of production scenarios is reflected on the unit's components through their failure rate. In this context, prognoses on possible resources problems are made by studying the characteristics of the generated plans. On the second hand, the withdrawals are now subjected to two decision criteria. In addition to minimizing the average total maintenance cost per unit of time on an infinite time horizon, the best achievable reliability of remaining turbo generators is sought. This problem is treated as a biobjective nonlinear optimization problem. Finally a series of problems describing multiple contexts are solved for planning renovations of 90 turbo generators units considering 3 major components in each unit and 2 types of maintenance policies for each component.

We start with a short presentation of the general theoretical framework and the operational concepts employed in our analysis, while insisting on the various meanings of exemplification. In a second step we examine the mathematical examples using quantitative textual tools before proceeding to a fine textual analysis of the marks of exemplification based on the method of analytical reading. We conclude by summarizing the main results of the analysis and discussing the prospects they reveal.

    Blogs, Facebook, Twitter, and other social media have proven themselves powerful vectors for science denial. Left unchecked, these attacks on foundational sciences like evolution and climate change undermine public confidence in science and spawn attacks on science-based policy and science education. Scientists can blunt such attacks by being vigorous advocates for their own research and their discipline's core findings, by seeking wide and unexpected audiences for discussions of their science, and by understanding and addressing the social, political, and cultural roots of science denial.

  19. Modelisation of synchrotron radiation losses in realistic tokamak plasmas

    International Nuclear Information System (INIS)

    Albajar, F.; Johner, J.; Granata, G.

    2000-08-01

    Synchrotron radiation losses become significant in the power balance of high-temperature plasmas envisaged for next step tokamaks. Due to the complexity of the exact calculation, these losses are usually roughly estimated with expressions derived from a plasma description using simplifying assumptions on the geometry, radiation absorption, and density and temperature profiles. In the present article, the complete formulation of the transport of synchrotron radiation is performed for realistic conditions of toroidal plasma geometry with elongated cross-section, using an exact method for the calculation of the absorption coefficient, and for arbitrary shapes of density and temperature profiles. The effects of toroidicity and temperature profile on synchrotron radiation losses are analyzed in detail. In particular, when the electron temperature profile is almost flat in the plasma center, as for example in ITB confinement regimes, synchrotron losses are found to be much stronger than in the case where the profile is represented by its best generalized parabolic approximation, though both cases give approximately the same thermal energy contents. Such an effect is not included in present approximate expressions. Finally, we propose a seven-variable fit for the fast calculation of synchrotron radiation losses. This fit is derived from a large database, which has been generated using a code implementing the complete formulation and optimized for massively parallel computing. (author)

    2007-01-01

    Petascale science is an end-to-end endeavour, involving not only the creation of massive datasets at supercomputers or experimental facilities, but the subsequent analysis of that data by a user community that may be distributed across many laboratories and universities. The new SciDAC Center for Enabling Distributed Petascale Science (CEDPS) is developing tools to support this end-to-end process. These tools include data placement services for the reliable, high-performance, secure, and policy-driven placement of data within a distributed science environment; tools and techniques for the construction, operation, and provisioning of scalable science services; and tools for the detection and diagnosis of failures in end-to-end data placement and distributed application hosting configurations. In each area, we build on a strong base of existing technology and have made useful progress in the first year of the project. For example, we have recently achieved order-of-magnitude improvements in transfer times (for lots of small files) and implemented asynchronous data staging capabilities; demonstrated dynamic deployment of complex application stacks for the STAR experiment; and designed and deployed end-to-end troubleshooting services. We look forward to working with SciDAC application and technology projects to realize the promise of petascale science

    Full Text Available This study takes a soft scientific cut to talks about rumors, hoaxes and urban legends. Social psychology, more elegantly, uses the latin word rumor (rumour in British English, which means sound, voice, or gossip. In social, economical, political, cultural and scientific communication, rumors indicate news that is presumed true, that circulates without being confirmed or made evident. The scientific history of rumors is briefly described starting from the period of ancient Rome, throughout the Second World War and the Internet era, up to today. We will try to answer some questions that can be useful to scientists today. What are rumors? How are they born? How do they spread? By which laws are they regulated? How do we need to fight them? A final question regards the collocation of rumors into modern science. Science today is divided into ‘hard’ and ‘soft’ science (the latter of which generally lacks a basic mathematical structure; these terms, respectively, indicate the natural sciences, which investigate Nature, and the social/human sciences, which investigate man in all his facets. Maybe rumors can be thought of as a bridge suspended between two banks: those of ‘scientific truth’ and ‘human truth’.

    Science activities that evoke positive emotional responses make a difference to students' emotional experience of science. In this study, we explored 8th Grade students' discrete emotions expressed during science activities in a unit on Energy. Multiple data sources including classroom videos, interviews and emotion diaries completed at the end of each lesson were analysed to identify individual student's emotions. Results from two representative students are presented as case studies. Using a theoretical perspective drawn from theories of emotions founded in sociology, two assertions emerged. First, during the demonstration activity, students experienced the emotions of wonder and surprise; second, during a laboratory activity, students experienced the intense positive emotions of happiness/joy. Characteristics of these activities that contributed to students' positive experiences are highlighted. The study found that choosing activities that evoked strong positive emotional experiences, focused students' attention on the phenomenon they were learning, and the activities were recalled positively. Furthermore, such positive experiences may contribute to students' interest and engagement in science and longer term memorability. Finally, implications for science teachers and pre-service teacher education are suggested.

    2005-01-01

    In the context of an introductory physical science course for non-science majors, I have been trying to understand how scientific visualizations of natural phenomena can constructively impact student learning. I have also necessarily been concerned with the instructional and assessment approaches that need to be considered when focusing on learning science through visually rich information sources. The overall project can be broken down into three distinct segments : (i) comparing students' abilities to demonstrate proportional reasoning competency on visual and verbal tasks (ii) decoding and deconstructing visualizations of an object falling under gravity (iii) the role of directed instruction to elicit alternate, valid scientific visualizations of the structure of the solar system. Evidence of student learning was collected in multiple forms for this project - quantitative analysis of student performance on written, graded assessments (tests and quizzes); qualitative analysis of videos of student 'think aloud' sessions. The results indicate that there are significant barriers for non-science majors to succeed in mastering the content of science courses, but with informed approaches to instruction and assessment, these barriers can be overcome.

    This book has a rather strange history. It began in Spring 1989, thirteen years after our Systems Science Department at SUNY -Binghamton was established, when I was asked by a group of students in our doctoral program to have a meeting with them. The spokesman of the group, Cliff Joslyn, opened our meeting by stating its purpose. I can closely paraphrase what he said: "We called this meeting to discuss with you, as Chairman of the Department, a fundamental problem with our systems science curriculum. In general, we consider it a good curriculum: we learn a lot of concepts, principles, and methodological tools, mathematical, computational, heuristic, which are fundamental to understanding and dealing with systems. And, yet, we learn virtually nothing about systems science itself. What is systems science? What are its historical roots? What are its aims? Where does it stand and where is it likely to go? These are pressing questions to us. After all, aren't we supposed to carry the systems science flag after we ...

    2015-09-01

    Full Text Available In the contemporary global world the various models of making and distributing science are cultivated. The particular model of institutionalized science can significantly determine the quality of working both as a scientist and as a student. Research upon science environment in the meaning of investigation the framework of science influences for example the system of communication between different actors engaged in science, good practices, possibilities offered by particular context of science and facilities of acquiring the scientific knowledge etc. It this view the presented paper finds its justification directing analysis towards the quality of making science. Hence the paradigm of sociological science policy is strongly needed. The paper is going to reconstruct the key models which recognize contexts of making science and its numerous dimensions. The research is based on the set of literature founded through the digital key words searching process. The chosen literature recalls the most significant research based on science policy. Consequently the described models tend towards the most globalized and open models of making science to show the path of required changes into still founded coercive science structures mostly institutionalized by long-lasting tradition. The final conclusion states that more concrete steps in reformulating the science policy are required to obtain the desirable model of open science and at the same time to develop the high standing scientific priorities.

    Kepler's mission design includes a comprehensive plan for commissioning and science operations. The commissioning phase completed all critical tasks and accomplished all mission objectives within a week of the pre-launch plan. Since the start of science data collection, the nominal timeline has been interrupted by two safe-mode events, several losses of fine point, and some small pointing adjustments. The most important anomalies are understood and mitigated, so Kepler's technical performance has improved significantly over this period, and the prognosis for mission success is excellent. The Kepler data archive is established and hosting data for the science team, guest observers, and the public. The first data to become publicly available include the monthly full-frame images and the light curves for targets that are dropped from the exoplanet program or released after publication. Data are placed in the archive on a quarterly basis; the Kepler Results Catalog will be released annually starting in 2011.

    NASA's strategic Goals: a) Develop a balanced overall program of science, exploration, and aeronautics consistent with the redirection of human spaceflight program to focus on exploration. b) Study Earth from space to advance scientific understanding and meet societal needs. NASA's partnership efforts in global modeling and data assimilation over the next decade will shorten the distance from observations to answers for important, leading-edge science questions. NASA's Applied Sciences program will continue the Agency's efforts in benchmarking the assimilation of NASA research results into policy and management decision-support tools that are vital for the Nation's environment, economy, safety, and security. NASA also is working with NOAH and inter-agency forums to transition mature research capabilities to operational systems, primarily the polar and geostationary operational environmental satellites, and to utilize fully those assets for research purposes.
