Science & Technology at Scientific American.com: Inconstant Constants -- [ COSMOLOGY ] -- Do the inner workings of nature change with time?

"One ratio of particular interest combines the velocity of light, c, the electric charge on a single electron, e, Planck's constant, h, and the so-called vacuum permittivity, 0. This famous quantity, = e2/20hc, called the fine-structure constant, was first introduced in 1916 by Arnold Sommerfeld, a pioneer in applying the theory of quantum mechanics to electromagnetism. It quantifies the relativistic (c) and quantum (h) qualities of electromagnetic (e) interactions involving charged particles in empty space (0). Measured to be equal to 1/137.03599976, or approximately 1/137, has endowed the number 137 with a legendary status among physicists (it usually opens the combination locks on their briefcases)."

Just kind of funny what numbers have meaning to different people, and that a whole class of people would pick some number like this as a password. I'm sure its true in other fields as well, I've just never heard of it before or stopped to think about it. You think IRS people use some combination of 1040 for their passwords?
