...spent some years in England's Cambridge as a Rockefeller fellow, joined the Institute at Princeton in 1936. In Cambridge he helped Physicist Max Born, another German exile (now at Edinburgh), in the formulation of a field theory which bridges modern Quantum Mechanics and the 19th-Century electro-magnetic wave equations of Scotland's brilliant James Clerk Maxwell (TIME, Sept...
...curves. After curved fields in space came waves of energy. The wave theory of light, which had been opposed by Newton, was picked up again because it was the only way to explain certain phenomena-for example, the diffraction rings produced when light passes through a small aperture. Before electro-magnetic waves (e.g., wireless waves) were ever demonstrated experimentally, Maxwell distilled them out of his mathematical equations, then showed that their velocity was equal to the velocity of light. Therefore, light appeared to be an electro-magnetic wave. This was one of the greatest achievements in the history of science...
Visible light does not penetrate thick fog, but visible light is only a small segment on the wide spectrum of electro-magnetic radiation. Radiation which is too long in wave length to be seen, called infra-red and embracing wireless waves of all lengths, has the faculty of sliding around obstacles such as fog particles. Therefore an artificial eye which "sees" by infra-red radiation appears to offer the best hope of piercing...
...cyclotron of Ernest Orlando Lawrence neatly finesses such troubles by making a comparatively small voltage act on a particle repeatedly until it attains a speed corresponding to extremely high voltage, thus dispensing with a discharge tube altogether. Most conspicuous feature of the apparatus is an 85-ton electro-magnet whose poles face each other vertically across an 8-in. gap. In the gap is placed a shallow cylindrical tank, pumped out to a high vacuum so that particles inside may move freely without interference from air molecules. Ions such as deuterons (nuclei of heavy hydrogen...
