...universe.* Planck's constant enabled Einstein to conceive the "photon" (particle of radiation). It also made possible Niels Bohr's model of the atom. It turned up in spectroscopy, in the study of X rays, in electronics. Upon it is based the whole science of quantum (wave) mechanics...
Bernstein took part in the wild battle in which 30 Jews and 11 British seamen were injured as the enraged refugees threw the initial boarding party over the side. A second wave overpowered the passengers and crew with fire hoses, clubs, and tear...
Practical consequences are not yet in sight, for the wave mechanicians work in a never-never land far beyond the frontier of practical technology. But Nobelman Rabi compared Lamb & Retherford's criticism of the Dirac theory with Einstein's modification of Newton's laws of motion. It took 40 years for Einstein's relativity to grow into the atom bomb...
...highly theoretical branch of physics which studies chiefly the interaction of mass and energy within the atom. Most scientists and practically all laymen get mentally seasick attempting to follow the wave mechanicians...
...photon (smallest unit of radiant energy) is equal to the frequency of the wave multiplied by Planck's constant h (6.55 X 10(-27)erg-seconds...
