Fuck me, I haven’t thought about bessel functions since college, but I still remember when they were introduced, for me, not in graduate physics, but in one of my earlier undergrad programming classes, the assignment went so poorly that the professor added a gimme question on the final exam, something like, “True or false: Simply seeing the words “bessel function” will raise my blood pressure.”

That, is the best. Thank you.

That was glorious!
