# Sigmas From Shoulder to Shoulder [Science Tattoos]

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. As a biochemist and molecular biophysicist I studied a lot of this stuff and I must say, Schroedinger was my favorite and well, I had to do it. The ink was done at Red Sky Studios in Tucson, AZ by artist Lisa.”
