De Broglie theory
As I remember the history of quantum mechanics (I write this from memory, I have no access to my books) Einstein (1905) postulated light quanta (later called photons) and De Broglie (1924) postulated in his thesis waves for matter (particles like electrons with non-zero rest mass). Compton showed that light momentum could be transferred into particle momentum (Xray scattering on nearly free hydrogen atoms). The present article is not in agreement with my memory, so who is right? --Paul Wormer 21:28, 21 April 2008 (CDT)
