Why Einstein thought Nuclear Weapons where Impossible

A few years ago I made a documentary about uranium, radioactivity and radiation. I always thought of the characters in our story as the scientists and maybe the uranium nucleus itself. It was only through making the documentary that I realised the real hero of the story is the neutron.

Without a neutral nuclear particle, it would be virtually impossible to release the energy from the nucleus. But with it, and the idea of a chain reaction, nuclear energy went from science fiction to reality.

That is something I had not grasped as clearly before and it motivated me to make this video.
