Yet students today are learning a horrific bastardized version of it. Physics is absolutely terrible when courses and books try to to remove the "complicated" math, and in its place they put something more complicated and ambiguous. Teach the math! It's like Greenspun's Tenth Rule, but for math: "Any sufficiently complicated scientific theory contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Complex Analysis."
