  range of the water, which differs for various species. Thus, for example, the increase in temperature of river water by only a few degrees as a result of heat dischargedfrom power plants may kill most of the native fish. See Water Pollution. The properties of all materials are also markedly affected by temperature changes. At arctic temperatures, for example, steel becomes very brittle and breaks easily,and liquids either solidify or become very viscous, offering high frictional resistance to...

  2 trouvés dans le noyau des cellules (lorsqu'on découvrit qu'ils se trouvaient aussi ailleurs, leur nom était déjà diffusé). Pendant des décennies, on se limita à en étudier la structure sans essayer d'en expliquer la fonction, et encore moins de les relier à la transmission des caractères héréditaires, car on imaginait que leur simplicité ne les prédisposait pas à une fonction aussi déterminante. Cependant, durant les années 20, on savait qu'il existait deux acides nucléiques, l'acide désoxyri...

• MÉCANIQUE QUANTIQUE INTRODUCTION La mécanique quantique est une théorie élaborée au début du XXe siècle pour rendre compte des résultats expérimentaux, de plus en plus nombreux, que la physique traditionnelle était incapable de prévoir et d'expliquer.

  2 2 Planck arriva au bon résultat en imaginant que l'énergie émise à une fréquence donnée ne pouvait qu'être un multiple entier d'un quantum d'énergie, proportionnel à la fréquence émise. La constante de proportionnalité est ce que l'on appelle maintenant la « constante de Planck », universellement notée h et dont la valeur est environ 6x10 -34 joule seconde. La fréquence de la lumière visible étant de l'ordre de 10 15 hertz, les quanta d'énergie ainsi introduits ont une valeur d'environ 10 -...

  Carnot EngineThe idealized Carnot engine was envisioned by the French physicist Nicolas Léonard Sadi Carnot, who lived during theearly 19th century. The Carnot engine is theoretically perfect, that is, it converts the maximum amount of energy intomechanical work.

• Electron I INTRODUCTION Models of the Atom Once scientists discovered the electron, they set out to explain how electrons behave in atoms.

  Electron Density and Orbital ShapesAtomic orbitals are mathematical descriptions of where the electrons in an atom (or molecule) are most likely to be found.These descriptions are obtained by solving an equation known as the Schrödinger equation, which expresses ourknowledge of the atomic world. As the angular momentum and energy of an electron increases, it tends to reside indifferently shaped orbitals.
