New Delhi: To mark the 127th birthday of Niels Bohr, Google today posted a doodle on its homepage. But who was was Niels Bohr?

Niels Bohr was a Danish physicist, who was awarded the Nobel Prize in Physics 1922 "for his services in the investigation of the structure of atoms and of the radiation emanating from them". Niels Henrik David Bohr was born in Copenhagen on October 7, 1885. His father, Christian Bohr was a Professor of Physiology at Copenhagen University.

The Niels Bohr 127th birthday Google doodle showcases his contributions to science and shows the Bohr atomic model. This model introduced by Bohr in 1913, was a radical departure from earlier descriptions of the atom and showed the atom as one with a small nucleus surrounded by electrons that travel in circular orbits in a structure similar to the solar system, with electrostatic forces providing attraction, not gravity.
