...Eugenio Bertozzi This paper retraces the biography of a milestone instrument in the history of physics—the cloud chamber—introduced by Charles Thomson Rees Wilson in 1911 and vastly adopted in successive studies on particle physics. It offers a comprehensive reading where the development of the...

..., or might be, taking place within any particular observation. The development of cloud chambers (or Wilson chambers, as they were often called up to the 1930s) established a means of photographing the tracks that individual charged particles had followed. As Clinton Chaloner has argued, in the 1910s...

.... Cosmic-ray physics had been marked by a rapid evolution since 1930. More precisely, it had advanced in unexpected directions, thanks to the application of two novel kinds of instruments, cloud chambers and electronic counters, and to the development of observational techniques that connected the out...
