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;)
