OK....I’ll bite. What’s that mean?

E = Mc²
E/c² = M

the best-known imaginary number, "the square root of -1," is represented by "i"

Ideal gas law in equation form: PV=nRT [where T means temperature]
PV = nRT
PV/nR = T

Therefore this is obviously a Mit Romney dog whistle, and no one should wear it anywhere near a polling place. For one thing, it will clash with the Obama mural.

Obama probably thinks the ideal gas is found inside a bong pipe/s;)
