Long before he moved from Germany to the Institute for Advanced Study at Princeton, Albert Einstein wrote an equation based on Planck's little constant h to explain how and why light falling on a metal kicks electrons out of the metal, setting up electric currents. This photoelectric effect is now familiar to laymen because it serves to open doors in restaurants and railway stations, operate drinking fountains...
...years ago that another brainy German, Max Planck, discovered that atoms do not radiate light continuously or in indiscriminate amounts, but in separate pulses and uniform quantities which were subsequently called quanta. Planck's constant, h, is equal to .00000000000000000000000000655 erg-seconds. For any sort of light the energy multiplied by the period of vibration is always equal to h. To a physicist grouping within the atom, h and the quantum mechanics which have grown up around it are as important as bait, hook & line to a fisherman...
...Modern Physics"?a picture he has displayed to some 300,000 readers in thin, lucid books. Sir James again led his hearers over the trail from the comfortable Victorian universe of jelly-like ethers, billiard-ball particles, gears and levers to the disconcerting, fantastic universe built by Rutherford, Planck. Bohr, Einstein. Heisenberg. Schrodinger, Dirac and others where the electron dances beyond space and time in a field of mathematical formulae...
Society for Advancement of Science he made what was considered a daring speech indeed. To have praised live Jew Albert Einstein would have been madness, but he did praise dead Jew Heinrich Hertz, discoverer of "Hertzian waves." And bold Max Planck said: "History proves that the greatest and most vital discoveries were made by scientists who worked for the sake of pure science only...
Indulgently Nazi Rust did not crack down on Professor Planck, but as president of the Society Herr Planck dolefully reported that 85 scientists have sent in their resignations and are suffering "economic difficulties" under the Nazi regime...
