Planck's Constant h

  1. Jul 14, 2008 #1
    Planck's Constant...."h"

    I am wondering if anyone knows why "h" was chosen for Planck's Constant? Or did they just randomly select a letter which didn't represent a constant at the time?
    Thanks.

    Re: Planck's Constant...."h"

    When Planck first published his results, he thought of h as an auxiliary quantity. In German an auxiliary quantity is called Hilfsgröße, which is - at least according to some historical reports about Planck's life - the reason, why he used h, the first letter of Hilfsgröße, to represent this constant.

    The "h" was for "helpless," because he realized that's how students would feel when they were first learning about this stuff.:smile:
