Recognize these equations?

    I got this awesome new watch with equations on it, but I don't recognize any of them (except E=mc^2 obviously). Anyone know what they could be referring to?

    You could still somewhat tell the time, the positions of the hands are the same :P
    That is an awesome watch! ;)

    One of them is the Poyinting vector: ##\vec {S} = \dfrac {1}{\mu_0}(\vec{E} \times \vec{B})## (It's the energy per unit time per unite area)

    I see an expression for kinetic energy in quantum mechanics on the bottom left, namely just the p^2.

    That equation below the delta IB has 8mL4 in the denominator. I recognize that from quantum mechanics, I think.
