Unknown equation

  1. May 12, 2009 #1
    Does anyone recognize this equation?

    [tex]
    \frac{k_BT}{2} = \alpha\frac{<x^2>}{2}
    [/tex]

    What does it describe?

    It look like something to do with Energy. Because the LHS has the unit of energy, while the RHS, hmm, looks a bit strange...

    Doesn't it have to do with ideal gas in a box?

    It is the average potential energy of a harmonic oscillator in the high temperature limit.
