Work

In developing quantum mechanical theory, Paul Dirac predicted that all matter has a kind of mirror image - antimatter. A particle and its antiparticle, if charged, should have opposite charges. By studying the tracks of cosmic ray particles in a cloud chamber, in 1932 Carl Anderson discovered a positively-charged particle with a mass seemingly equal to that of an electron. Carl Anderson's particle was the first antiparticle proven by experiment and was named a "positron".
