I had an almost identical conversation with some engineering major roommates after a heavy mushroom trip in 1984. We were in four simultaneous classes that applied DiffEq, and IMHO, the first time you grasp DiffEq you feel like someone gave you a way to describe anything. So: we spent hours describing the differential equations of thought evolution, vision, perception, hearing, and existence. We hadn't encountered Hamiltonians yet, but I'm sure we would have thrown them into the mix. Yeah, drugs will do that to you. Make you think every thought you have is pure gold.
