Comment refroidir des atomes grâce à des lasers pour mieux les observer ? C'est dans les années 1920 que l'hypothèse selon laquelle toute particule de matière est également une onde est vérifiée. Cette « dualité onde-corpuscule » est un des fondements de la physique quantique, et un de ses éléments les plus paradoxaux. Pour observer ces propriétés ondulatoires avec des atomes ou des molécules, il faut que leur mouvement soit très lent, et donc qu'ils soient très froids. C'est à cela que se consacre Jean Dalibard : refroidir des gaz d'atomes au plus près du zéro absolu, vers –270 °C.

Atoms and Ashes recounts the dramatic history of nuclear accidents that have dogged the industry in its military and civil incarnations since the 1950s. Through the stories of six terrifying major incidents—Bikini Atoll, Kyshtym, Windscale, Three Mile Island, Chernobyl, and Fukushima—Cold War expert Serhii Plokhy explores the risks of nuclear power, both for military and peaceful purposes, while offering a vivid account of how individuals and governments make decisions under extraordinary circumstances.

The following is the audio track for the 1953 promotional animated short documentary film created by John Sutherland and sponsored by General Electric explaining what an atom is, how nuclear energy is released from certain kinds of atoms, the peacetime uses of nuclear power, and the by-products of nuclear fission.

Jede Zahl, mit der wir messen, hat eine Vorgeschichte. Der Meter sollte der zehnmillionste Teil des Erdmeridians sein — und ist bis heute um zwei Zehntelmillimeter zu kurz, weil zwei Astronomen sich mitten in der Französischen Revolution verrechneten. Das Urkilogramm nahm im Tresor heimlich...

Claude Cohen-Tannoudji, prix Nobel de physique 1997, retrace son itinéraire personnel et scientifique et un demi-siècle d'évolution de la physique quantique. Sur ce sujet nul n'est mieux placé que lui, qui en a extrait les applications les plus caractéristiques et les plus étonnantes à la fois: la domestication –; et en particulier le refroidissement –; des atomes à l'aide de la lumière. La genèse de ces résultats révolutionnaires –; dont les applications commencent seulement à poindre aujourd'hui –; constitue un témoignage unique sur le développement de la physique et des techniques du XXè siècle.
