Classes
I have three classes this semester:
Geophysical Fluid Dynamics -- this is fluid dynamics as applied to the ocean and atmosphere -- the physics of a thin layer of stratified fluid in a rotating reference frame.
Geological Oceanography -- this is the geology of the ocean basins -- plate tectonics, sediments, all sorts of stuff. It's being taught by an emeritus faculty who has witnessed continental drift personally. Mostly the lectures are him telling his life story. He did an amazing number of things, but I'm not sure I'm learning anything.
Small Scale Physics -- this one is so far mostly about turbulence and mixing, and it scares me. Usually it takes about three weeks for me to get lost in a physics class, even an upper-level one, but I was pretty much lost fifteen minutes into the first lecture, on the generation of entropy in a binary fluid.
Even the professor is struggling a little with this material, which is a hopeful sign. I've had professors struggle with material before, but it's always been because they were incompetent. A competent instructor struggling to teach me something new is the first hint that I may soon know enough to do something useful, I think.
