Just helped my girlfriend through a semester of non-calculus E&M. She said, "I've noticed that the average power in an AC circuit is 1/2 of what it is for a DC circuit when you have the same voltage and current. Why?". And so I tell her "Because the integral of sin^2(x)dx is 1/2 over n-number of cycles. Now, if you want to know why that's true... well, do you have 5 spare hours before your final in the morning?". So non-calculus physics just revolves around memorizing formulas, which is no way to truly comprehend the concepts of physics. In fact, a disdain of route memorization attracted me to physics in the first place.
I think about that ranking on average every 3 to 4 months, and usually agree. Edit: ...that it's written by someone who likes math and physics like myself. Oh and also, my sister has a degree in sociology, and she's accomplished some things that put me to shame.
