Differential equations seemed simple after I had completed Calc 1, Calc 2, Calc 3, and especially "Mathematical Methods in Physics" at LSU.
Dr. Paul Kirk made a MathGeek out of me in that Mathematical Methods in Physics course. I can hear him now, "A tensor must obey the tensor transformation laws." Huh? I still have no idea what a tensor really is other than obeying the tensor transformation laws and being able to be manipulated like a matrix (I'm good at linear algebra).
