Philip Ball looks at how a little-known paper by Niels Bohr demonstrates the turmoil in physics on the brink of quantum ...

Niels Bohr was born and educated in Copenhagen, Denmark. He lived, worked, and died there, too. But his mark on science and history was worldwide. His professional work and personal convictions ...

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 ...

When an electron dropped from a high-energy orbit to a lower-energy one, it gave out light with an energy equal to the ...

In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons ... However, there was still a difference between the atomic number of the atom and the atomic mass.

The Theory of Everything ... such as Sir Roger Penrose (a Steven Hawking's mentor), Steven Meyer (ID), Niels Bohr (atomic structure), Sir John Eccles (Nobel Prize for consciousness), Max Planck ...

Niels Bohr adapted Ernest Rutherford's nuclear model. Bohr did calculations that led him to suggest that electrons orbit the nucleus in shells. The shells are at certain distances from the nucleus.

In 1927, Werner Heisenberg was in Denmark working at Niels Bohr's research institute in Copenhagen. The two scientists worked closely on theoretical investigations into quantum theory and the ...
