...could duplicate on earth the 40.000.000° C. at which the sun's centre boils, he might do what he wished with electrons and protons. At that temperature matter's subunits dance around each other and coalesce as atoms; atoms break up into their electron and proton elements; and every explosion, every coalescence scatters atomic energy. Professor Compton cannot duplicate solar heat, but with a mighty X-ray tube, he calculates, he can drive particles of matter at speeds so nearly solar that new atoms will result. His tool will be a 10,000-volt tube, five times...
...Savants Einstein, Tolman & Podolsky prove that it is impossible to say exactly where that electron was before it struck the measuring device...
...uncertainty of the future has been accepted by physics. Physicists can foretell the general action of a vast aggregate of, say, electrons. But they cannot say how any individual electron will behave. Their difficulty lies in the fact that the instant they recognize an electron, the electron disappears or changes its condition by reaction with the measuring device...
...crowd are identical triplets? Mary, Marie, Marion?dressed exactly alike. The observer thinks he recognizes Mary (an electron). He taps her on the shoulder. She turns around. Now the observer does not know whether she is Mary, Marie or Marion. Her identity is uncertain. The tapped girl pauses and may decide not to go to the show that evening. As a theatre-going electron she therefore disappears...
...found in experiments with weak electromagnetic and gravitational fields. Additional work on stronger fields and in terrestrial magnetism is still needed to check him. The theory, says Dr. Einstein, provides a conception for a new geometry of space having for constants the speed of light, the charge of an electron, the mass of an electron, the mass of a proton, and Max Planck's wave-corpuscular light constant...
