I had a thread a bit ago in which I explained how I was getting different advice from the physics and math departments. A physics professor thought I should jump right into the calculus, while the math department thought I should take precalculus first. I encountered another issue in which these two departments disagree on the other night. I was at an astronomy viewing session talking to a physics professor who was there. He said that he and other physics professors weren't satisfied with the way the math department was teaching. He believed their methods made students too dependent on a graphing calculator. I have yet to get the perspective from the math professors on this issue, but I've taken to limiting my use of the calculator as much as possible to acquire the necessary skills. This intrigues me, nonetheless. Are these sorts of disagreements common-place? Does it happen at all universities? What other issues do these departments disagree on? And who's word should I take for it?
