Main Question or Discussion Point
* In 1928, PHYSICIST and nobel prize winner Max. born told a group of visitors to gottingen university "physics , as we know it, will be over in six months".His confidence was based on recent discovery by DIRAC of the equation that governed the electron.It was thought that a similar equation would govern the proton , which was the only other particle known at that time and that would be end of theoretical physics. however the discovery of neutron and of nuclear forces knocked that one on the head, too. my question is how could it say that physics could be over and how did neutron save the physics?
