Niels Bohr was one of the foremost scientists of modern physics, best known for his substantial contributions to quantum theory and his Nobel Prize-winning research on the structure of atoms. Born in ...

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 ...

For millennia, atoms had been phantoms, widely suspected to exist but remaining stubbornly invisible — though not indivisible, as their name (Greek for “uncuttable”) originally implied. By the start ...

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 ...

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 ...

On 2 April, 1913, Niels Bohr wrote to his wife Margrethe: “My dearest little one. Rutherford should only know that it is you who have to do it all.” Bohr had just had a discussion with Ernest ...

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 ...
