Google celebrates Niels Bohr with atom doodle

Niels Bohr Doodle

Niels Bohr Doodle

Niels Bohr was a danish physician. Google celebrates his 127th birthday with a nice Doodle. Bohr made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. The doodle shows a model of a hydrogen atom. Around the Nucleus you can see three orbits. If an electron „jumps“ in another orbit it emitted a photon of energy with a specific frequency. The background looks like a radioactive trace.

Here the doodle:

Niels Bohr

Niels Bohr

Niels Henrik David Bohr was born in Copenhagen on October 7, 1885, as the son of Christian Bohr, Professor of Physiology at Copenhagen University, and his wife Ellen, née Adler. Niels, together with his younger brother Harald (the future Professor in Mathematics), grew up in an atmosphere most favourable to the development of his genius – his father was an eminent physiologist and was largely responsible for awakening his interest in physics while still at school, his mother came from a family distinguished in the field of education. … Read on at Nobleprize.org/Niels_Bohr

Bohr mentored and collaborated with many of the top physicists of the century at his institute in Copenhagen. He was part of the British team of physicists working on the Manhattan Project. Bohr married Margrethe Nørlund in 1912, and one of their sons, Aage Bohr, grew up to be an important physicist who in 1975 also received the Nobel Prize. Bohr has been described as one of the most influential scientists of the 20th century. He died on November 18th, 1962. More abou his live and works at Wikipedia/Niels Bohr.

The Bohr Model

As said the doodle shows a Bohr-Model of an atom. Here is another picture that shows in principle the same:

In atomic physics, the Bohr model, introduced by Niels Bohr in 1913, depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus—similar in structure to the solar system, but with electrostatic forces providing attraction, rather than gravity. This was an improvement on the earlier cubic model (1902), the plum-pudding model (1904), the Saturnian model (1904), and the Rutherford model (1911). Since the Bohr model is a quantum-physics–based modification of the Rutherford model, many sources combine the two, referring to the Rutherford–Bohr model. More
