C.T.R. Wilson

Died 15 Nov 1959 at age 90 (born 14 Feb 1869).Scottish physicist who shared (with Arthur H. Compton), the 1927 Nobel Prize for Physics for his invention of the Wilson cloud chamber, which became widely used in the study of radioactivity, X rays, cosmic rays, and other nuclear phenomena. His discovery was a method of rendering visible the tracks of such electrically charged particles. It is based upon the formation of clouds, which develop when sufficiently moist air is suddenly expanded, thus dropping the temperature below the dew-point. Thereafter, vapour condenses into small drops, formed round dust particles, or even, an electrically charged atomic particle. The formation of droplets is so dense that photographs show continuous tracks of particles travelling through the chamber as white lines.
