Niels Bohr won a Nobel Prize for the idea that an atom is a small, positively charged nucleus surrounded by orbiting electrons. He also contributed to quantum theory.

Bohr entered the story in 1912 when, working in the laboratory of Ernest Rutherford in Manchester, he devised a quantum theory of the atom. In Bohr’s picture, the electrons encircling the atomic ...

Bohr was the first physicist to look to the then-emerging quantum theory to try to explain the behavior of the particles inside the simplest of all atoms; the atom of hydrogen.

Bohr's theory explains the mutual orbit of electrons and positrons just before they annihilate each other, transforming into gamma rays that give rise to the PET scan image.

Bohr's quantum theory revised Date: February 7, 2017 Source: Plataforma SINC Summary: Bohr’s atomic model was utterly revolutionary when it was presented in 1913 but, although it is still taught ...

This challenge has been around for as long the subject itself, with both Niels Bohr and Albert Einstein debating the implications of various thought experiments as far back as 1927. For Bohr, the ...

The theory was developed by Neils Bohr's great-grandson. The use of a special type of atom could make even the most advanced atomic clocks more precise, scientists believe. If confirmed, this ...
