Do not always relate nerdness to sexieness, it really gets frustrating, when you sit for hours on quantum probability like <x-1>a<1-x> = P = aΦ and you finally managend to combine that with the relativistic impulse, what is E - p²c²=m²c² and you run with those great glowing eyes to your wife and explain it in detail, when she says: "ouh dear, you are so sexy when you explain things."
That IS really frustrating
