Everyone at that time imagined the atom as a "plum pudding ... planets around the sun. In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right.

For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model ...

Electron Boogaloo - Today we're exploring one of Albert Einstein's most controversial papers: his ideas on the photoelectric ...

Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. Bohr's 'solar system' model of the atom is the way that most people think ...

This lecture marks a key moment in Bohr’s scientific journey, coming shortly after he had developed his model of the atom, which had revolutionized the field of atomic physics. Here’s a ...

Constantinos G. Vayenas discusses how our Universe was made, focusing on positron and electron catalysis of neutrino ...
