Niels Bohr was the Danish national team goalkeeper He is also the Olympic silver medallist]]> 2017-03-22 06:36:42 UTC https://padlet.com/guduanning79/9ljo089aipoa/wish/161715713 because he made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. 1814685113 https://padlet.com/guduanning79/9ljo089aipoa/wish/161715799 2017-03-22 06:37:34 UTC https://padlet.com/guduanning79/9ljo089aipoa/wish/161715799 https://padlet.com/guduanning79/9ljo089aipoa/wish/161715866 Fun fact #1: Niels played soccer and was on the college team (He was not as good as his brother who played Denmark and won silver in the 1908 Olympics.)

Fun Fact #2: Niels and Margethe's son, Aage, followed in his fathers footsteps in physics. Aage also won the Nobel Peace Prize (like Niels) in 1975.

Fun Fact #3: Niels Bohr's Institute of Theoretical Physics was sponsored by Carlsberg Brewery (Famous Danish Brewery) 

Fun Fact #4: During WWII, Bohr offered a place for Jewish Scientists to live and work.

Fun Fact #5: Not only did Bohr make major contributions to theoretical physics, he was also a wonderful administrator.

Fun Fact #6: During the debate about Quantum Theory with Albert Einstein, Einstein said "God does not play dice." Bohr replied by saying "Einstein, stop telling God what to do!"

Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy.Bohr founded the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute, which opened in 1920. Bohr mentored and collaborated with physicists including Hans Kramers, Oskar Klein, George de Hevesy, and Werner Heisenberg. He predicted the existence of a new zirconium-like element, which was named hafnium, after the Latin name for Copenhagen, where it was discovered. Later, the element bohrium was named after him.During the 1930s, Bohr helped refugees from Nazism. After Denmark was occupied by the Germans, he had a famous meeting with Heisenberg, who had become the head of the German nuclear weapon project. In September 1943, word reached Bohr that he was about to be arrested by the Germans, and he fled to Sweden. From there, he was flown to Britain, where he joined the British Tube Alloys nuclear weapons project, and was part of the British mission to the Manhattan Project. After the war, Bohr called for international cooperation on nuclear energy. He was involved with the establishment of CERN and the Research Establishment Risø of the Danish Atomic Energy Commission, and became the first chairman of the Nordic Institute for Theoretical Physics in 1957. https://padlet.com/guduanning79/9ljo089aipoa/wish/161716059 2017-03-22 06:40:59 UTC https://padlet.com/guduanning79/9ljo089aipoa/wish/161716059 He made foundational contributions to understanding atomic structure and quantum theory, https://padlet.com/guduanning79/9ljo089aipoa/wish/161716064 2017-03-22 06:41:03 UTC https://padlet.com/guduanning79/9ljo089aipoa/wish/161716064 https://padlet.com/guduanning79/9ljo089aipoa/wish/161716151 2017-03-22 06:42:07 UTC https://padlet.com/guduanning79/9ljo089aipoa/wish/161716151 https://padlet.com/guduanning79/9ljo089aipoa/wish/161716258 2017-03-22 06:43:01 UTC https://padlet.com/guduanning79/9ljo089aipoa/wish/161716258
