Niels Bohr (1885–1962) was a Danish physicist who created the first widely accepted model of atomic structure. In three articles published in 1913, he proposed the Bohr model of the atom. Faced with the opposing particle and wave interpretations of atomic phenomena in the new quantum mechanics, he proposed the complementarity principle of using both interpretations to fully explain the results. Bohr received the Nobel Prize in Physics in 1922. He founded the Institute of Theoretical Physics in Copenhagen, now known as the Niels Bohr Institute. He correctly predicted the properties of an undiscovered element, hafnium. Later, the element bohrium was named after him. During the 1930s, Bohr helped refugees from Nazism and in September 1943 fled to Britain to avoid arrest by the Germans. There he joined the Tube Alloys nuclear weapons project, and later the Manhattan Project. After the war, he was involved with the establishment of CERN.

___________________________ Wikiquote quote of the day:

I don't say "Ho-ho-ho", but I do say "Oh-oh-oh" when I look out of the window, where I can see a night, then the evening, and then the night again. The 20 days of my transportation were pretty exhausting, but I'm still in a good mood, as befits a Santa Claus. … I was transported with such precaution and on such a strange route … I didn't expect anyone to find me here before mid-January. That's why I was very surprised when the cell door was opened yesterday with the words: "A lawyer is here to see you". He told me that you had lost me, and some of you were even worried.
