I kind of had a borderline religious experience in college calculus too. We had a handful of problems back to back: how long has a murder victim been dead? How hot does a fast food chain have to make their coffee so it burns their customers taste buds so they can't taste it? How long does it take the moon to orbit the earth? And we solved all these problems the same way. There was finally a grand order and purpose to all of it that was everywhere all the time.
