Recognize these equations?

[Chloe Soza]

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?

Looks mostly like electrical engineering and EM equations, e.g., β = ΔI_C /ΔI_B, which is the transistor gain: http://en.wikipedia.org/wiki/Bipola...ers:_alpha_.28.CE.B1.29_and_beta_.28.CE.B2.29

I think another equation is E =1/2 ħ √(k/m)

You could still somewhat tell the time, the positions of the hands are the same :P
offtopic:
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 I_B has 8mL⁴ in the denominator. I recognize that from quantum mechanics, I think.
