My friend was a math major. I remembered him saying something about Calculus IV. He might as well as told me he saw bigfoot. Prompted by these memories, I just watched part of a video of a Calc IV class. At first I thought: maybe I could understand it with sufficient effort. After a couple minutes of brain ache I concluded they were just trying to make something (still have no idea what) unnecessarily complicated. That was the problem I had with advanced math - it had no apparent relevance. Like running on a treadmill, it just gets boring and painful. I can accept that Calc IV - like bigfoot - exists and that somebody has seen it in real life (perhaps that video was a spoof and I have a sneaking suspicion it was...) but it still seems kinda crazy.
