Les joies de la physique

Dans la New York Times il y a un article sur John Grunsfeld, un astronaute qui a réparé et amélioré le Hubble Space Telescope plusieurs fois.
Un passage qui m'a particulièrement plu:

One of the attractions of that lifestyle is unique to physicists. When the shuttle passes through a zone in its orbit called the South Atlantic Anomaly, astronauts are exposed to large doses of cosmic rays, high-energy particles from the Sun or distant galaxies, which leave a wake of visible light as they pass through a dark-adapted human eyeball.

“In space you can get in touch with your quantum self,” Dr. Grunsfeld said. “I was a human cosmic ray detector.” He said he could identify the different kinds of particles zooming through his eyeball by how bright the flashes were.
