Hi. I have raised some concerns on the talk page of the Speed of light article about its current coverage of Roemer's work. Since you appear to have been responsible for the current form of this part of tharticle, I would appreciate any contribution you might want to make to the discussion.

I have conducted a reassessment of the above article as part of the GA Sweeps process. I have found some concerns with the artcile which you can see at Talk:Jacob Riis/GA1. I have placed the article on hold whilst these are fixed. Thanks. Jezhotwells (talk) 19:39, 8 August 2009 (UTC)[reply]

This is a note to let the main editors of

atomic structure. A central figure of 20th-century physics, he received the Nobel prize in 1922. In three articles published in 1913, the third in November, he applied old quantum theory to restrict the revolving electrons to stable orbits, creating the Bohr model of the atom. A dozen years later, 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. He founded the Institute of Theoretical Physics in Copenhagen, now known as the Niels Bohr Institute, and predicted the existence of a new element, which was named hafnium after the Latin name for Copenhagen. Later, the element bohrium was named after him. During the 1930s, he helped refugees from Nazism. In September 1943, after receiving word of his impending arrest by the Germans, he fled to Sweden. Flown next to Britain, he joined the British Tube Alloys nuclear weapons project, and later the Manhattan Project. After the war, Bohr was involved with the establishment of CERN. (Full article...
