(2) Since the coins are distinct, there are two outcomes which produce a head and a tail. The probability of two heads is one-quarter.

Bose–Einstein condensate

Einstein also did not at first realize how radical Bose's departure was, and in his first paper after Bose, he was guided, like Bose, by the fact that the new method gave the right answer. But after Einstein's second paper using Bose's method in which Einstein predicted the Bose-Einstein condensate (''pictured left''), he started to realize just how radical it was, and he compared it to wave/particle duality, saying that some particles didn't behave exactly like particles. Bose had already submitted his article to the British Journal ''Philosophical Magazine'', which rejected it before he sent it to Einstein. It is not known why it was rejected. Einstein adopted the idea and extended it to atoms. This led to the prediction of the existence of phenomena which became known as

Nobel Prize nomination

S.N. Bose was nominated by K. Banerjee (1956), D.S. Kothari (1959), S.N. Bagchi (1962), and A.K. Dutta (1962) for the Nobel Prize in Physics, for his contribution to

fundamental particles In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. Particles currently thought to be elementary include electrons, the fundamental fermions ( quarks, leptons, a ...

. (2). During the period from 1953 to date, he has made a number of highly interesting contributions of far-reaching consequences on the subject of Einstein’s Unitary Field Theory.” Bose's work was evaluated by an expert of the Nobel Committee, Oskar Klein, who did see his work worthy of a Nobel Prize.
