...between U. S. and European scientists which became patent last week when five Nobel Laureates from Europe* joined two from the U. S.† at the convention of the American Association for the Advancement of Science in Chicago. Americans work primarily with instruments. Europeans with imagination. Thus Danish Niels Bohr's philosophizing about the unmeasurable duality of Nature before the A. A. A. S. was a fascinating novelty which his audience tried hard to understand...
Professor Bohr, who has invented a very useful description of the atom, first pointed to Professor Einstein's relativity laws which say that we can never measure absolute time. Next he referred to Professor Werner Heisenberg's proof that we cannot measure at the same instant both the speed and the position of an electron, that the more exactly we determine the speed of electrons in an atom the less certain we can be of the position of the electrons in an atom. Thus, we can never say precisely what is Cause or what is Effect. The Heisenberg...
Relativity and uncertainty are absolute facts, reasoned Theorist Bohr in effect. Through them mathematicians are able to describe the tremendous, strange activities within an atom. But only one kind of activity at a time. For, the essential nature of atomic (or quantum) mechanics is duality. You can determine where an electron is or how fast it is moving, but not both facts simultaneously...
...turn with reasonable hopefulness to Russell's The A B C of Atoms, Sullivan's Three Men Discuss Relativity. In this brief (220-page), disarming autobiography, Journalist Sullivan, calling himself Julian Shaughnessy, explains about himself with the same simple sincerity he uses to explain Bach or Bohr. Realistic, humble, Sullivan calls popular works on science "one of the most unprofitable of all forms of reading," admits ''it seems that I am a man without any marked talents." He wrote his autobiography under the common desire to understand and justify his own existence. Son of an Irish...
...Edwin C. Kemble and Professor John C. Slater, now Lecturer at Harvard, as well as head of the Department of Physics at the Mass. Institute of Technology, specialize in theoretical physics. They have given much attention to the general theory of radiation, as based upon the conceptions of Planck, Bohr, Einstein and others...
