3 lines Sigmas equations From Shoulder to Shoulder

Joe writes about his 3 lines Sigmas equations From Shoulder to Shoulder "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 he studied a lot of this stuff and he must say, Schroedinger was my favorite and well, He had to do it.
