Bohr went on to make enormous contributions to physics and, like Rutherford, to train a new generation of physicists. But his atomic model remains the best known work of a very long career.

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 ...

Based on an experiment at CERN, a collaboration led by the Niels Bohr Institute, University of Copenhagen, can predict hitherto unchartered changes in the shape of nuclei.

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 ...

The atom is a complex system of particles ... Chemical reactions result from interactions between the electrons in two atoms.

Standard quantum theory as developed by the likes of Niels Bohr and Werner Heisenberg in ... Two quantum field theories lie at the heart of the standard model of particle physics.

There’s quantum mechanics, the basic mathematical framework that underpins it all, which was first developed in the 1920s by Niels Bohr ... the strong nuclear force, which explains the stability ...
