Text: "Most scientific discoveries were similarly at first at variance with widely held belief. Even Planck's major finding that light was radiated in "quanta" or units of action, such that their energy divided by the frequency was always the same, was not generally accepted for 25 years." Arthur Young the constant of proportionality relating the energy of a photon to its frequency; approximately 6.626 x 10\-34 joule-second
