Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...

Skimming through the latest issue of CavMag – a glossy newsletter about the latest developments at the Cavendish Laboratory, Cambridge – I at first thought I had misread an article that stated: “In ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus. By doing this, he was able to ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

What is it that leads rather gifted children to become Einstein, Bohr, Rutherford or Heisenberg W , those great physicists of the 20th century? Biographies often reveal forks in the road, moments of ...

Our understanding of the quantum world began with Niels Bohr's discovery of the quantum atom in 1913. Bohr would be astounded by where his theory has since led, says Professor David Jamieson. Bohr's ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...

In 1911 the New-Zealand-born physicist Ernest Rutherford published a paper that was to revolutionize science. Rutherford’s famous alpha-particle scattering experiment transformed our understanding of ...
