Le Monde des Eaux Douces

Le monde des eaux douces
Giles Walker, 1976, 24 min 22 s
Court métrage documentant les importants travaux accomplis par l'Institut des eaux douces, à Winnipeg, au Manitoba, dans le but de préserver et de protéger cette richesse incontestable.

Tout en démontrant une grande distance entre la technologie scientifique des années 76, ce film démontre les préoccupations environnementales qui animaient les scientifiques de cette époque.

Pliable Proteins KeepPhotosynthesis on the Light Pato

Caption: The reactions that convert light to chemical energy happen in a millionth of a millionth of a second, which makes experimental observation extremely challenging. A premier ultrafast laser spectroscopic detection system established at the Biodesign Institute, with the sponsorship of the National Science Foundation, acts like a high-speed motion picture camera. It splits the light spectrum into infinitesimally discrete slivers, allowing the group to capture vast numbers of ultrafast frames from the components of these exceedingly rapid reactions. These frames are then mathematically assembled, allowing the group to make a figurative "movie" of the energy transfer events of photosynthesis.
