Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

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 the ...

Danish physicist Niels Henrik David Bohr made foundational contributions to understanding the atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
