Why was the particle accelerator invented? Who made the first hydrogen bomb? Why does nuclear decay occur? Why are deuterium and tritium used in fusion? Why were the proton and electron discovered before the neutron? Why is mass not conserved in a nuclear reaction?
In 1932, he tried similar experiments himself, and became convinced that the radiation ejected by the beryllium was in fact a neutral particle about the mass of a proton. ... Scientists soon realized that the newly discovered neutron, asan uncharged but fairly massive particle, could be used ...
Heisenberg submitted the first of three papers on his neutron-proton model of the nucleus. 当时他的研究已经处在核技术的最前沿,但是, After Adolf Hitler came to power in 1933, Heisenberg was attacked in the press as a "White Jew" (an Aryan who acts like a Jew). From the early 1930s on...
