Sigmas From Shoulder to Shoulder
Joe writes, “My tattoo is 3 lines of equations, the top is the Born Oppenheimer Approximation, the second line is the equation in the form of a 3-Dimensional Schroedinger Equation, and the solution in the form of a Schroedinger Equation.
I sport a much cooler - and more comprehensive - full-body tattoo of string theory. Unfortunately to see the full thing you have to be able to see in 11 dimensions. All that shows up in our 4 dimensions is a tattoo of chinese symbols that my Chinese friend says questions my “orientation”. I can’t believe how lucky I was to find the tattoo guy that was an expert in string theory AND was willing to give me an 11-dimensional tattoo for only $20.
