La limite théorique de résolution en microscopie optique classique(en champ lointain) suit le critère de Rayleigh, qui donne la résolution latérale optimale à 1. 22 [lambda]/(2n sin[(thêta) ], soit environ 250 nm dans le spectre visible. Cette résolution peut être améliorée en augmentant l'ouverture angulaire et en utilisant un microscope à immersion pour augmenter l'indice de réfraction, et bien sûr en diminuant la longueur d’onde [lambda]. 1, record 1, French, - microscope%20%C3%A0%20immersion

The major windows are the visible window, from 0.3 to 0.9 m; the infrared window, from 8 to 13 m; and the microwave window, at wavelengths longer than 1 mm.

El balance de energía en el sistema Tierra -atmósfera se establece de acuerdo a la relación que existe, en término medio, entre la radiación el sol que penetra en la atmósfera y la radiación saliente de onda larga. La radiación saliente, que escapa por la ventana atmosférica, se equilibra con la radiación solar entrante. Por lo tanto, la atmósfera como la superficie están más calientes de lo que estarían en el caso de que no existieran los gases de efecto invernadero (IPCC, 1990). 3, record 4, Spanish, - ventana%20atmosf%C3%A9rica

Heisenberg Uncertainty Principle. An odd aspect of Quantum Mechanics is contained in the Heisenberg Uncertainty Principle (HUP). The HUP can be stated in different ways, let me first talk in terms of momentum and position. If there is a particle, such as an electron, moving through space, I can characterize its motion by telling you where it is (its position) and what its velocity is (more precisely, its momentum). Now, let me say something strange about what happens when I try to measure its positions and momentum. In the Quantum Mechanical world, the idea that we can measure things exactly breaks down. Let me state this notion more precisely. Suppose a particle has momentum p and a position x. In a Quantum Mechanical world, I would not be able to measure p and x precisely. There is an uncertainty associated with each measurement, e.g. there is some dp and dx, which I can never get rid of even in a perfect experiment!!!. This is due to the fact that whenever I make a measurement, I must disturb the system. (In order for me to know something is there, I must bump into it.) The size of the uncertainties are not independent, they are related ... 2, record 6, English, - Heisenberg%20uncertainty%20principle

Commençons par le principe d’incertitude d’Eisenberg : Il affirme qu'on ne peut pas connaître avec précision à la fois la position et la vitesse d’une particule. [...] Si l'on ne peut pas connaître sa position et sa vitesse, c'est parce que qu'une particule quantique n’ étant pas ponctuelle, n’ a pas à la fois une position et une vitesse définies(c'est un autre univers). Les objets quantiques admettent tout un spectre de valeurs pour la position et la vitesse. Cette limite ne porte pas sur la précision des mesures; elle porte sur la validité des concepts classiques pour une particule quantique. 1, record 6, French, - principe%20d%27incertitude%20d%27Eisenberg
