Rutherford told Bohr: « this cannot Work! », and It became The Foundation of Physics

My name is Ernest Rutherford. In the spring of 1912, a young Dane arrived at my laboratory in Manchester with a problem I had created and could not solve.

I had proved that the atom had a nucleus. It was the most important discovery of my life. And it was broken. Every physicist in Europe knew it could not work — classical physics demanded that electrons spiral inward and hit the nucleus in one hundred millionths of a second. Every atom in the universe should collapse almost instantly.

But you are made of atoms. The sun has been burning for four and a half billion years. Atoms do not collapse. We know this because we exist.

Niels Bohr was twenty-six years old. He could not fix it — not with any physics that existed. And he did it anyway. I told him it could not work. He sent me a long reply. He was courteous and precise and absolutely unmoved.

Because the numbers were correct. Bohr’s model predicted every line in the hydrogen spectrum — not approximately, exactly — for the first time in the history of physics. What I told him could not work became the foundation of everything that followed. Every element in the periodic table. Every laser. Every nuclear power station. The reason your body holds together at all.

In the end, he was always right.

What does the Electron look like?

A lecture by Dr Rodney Brooks of Harvard University

held at the Czech Technical University in Prague. Rodney A. Brooks, is the author of a book titled « Fields of Color: The theory that escaped Einstein ».(http://www.quantum-field-theory.net). Dr. Brooks shows why the field picture of the electron is much more satisfactory than the particle picture.
