Why this formula appears here
Albert Einstein’s paper “On a Heuristic Point of View Concerning the Production and Transformation of Light” reached the editors of Annalen der Physik on 18 March 1905 and was published that June, one of four papers from what is now called his annus mirabilis [ 1 ] . Its actual claim is narrower than the “light is made of particles” shorthand it gets today. Einstein proposed, as a heuristic — his own word, chosen because he was not yet willing to overturn the wave theory that already explained diffraction and interference — that “the energy of a light wave emitted from a point source is not spread continuously over ever larger volumes, but consists of a finite number of energy quanta that…
