Reading 1

I know I'm the only one not taking the exam, so who knows what you guys all thought of the lecture. I think it's pretty sweet.

With that, let's dive right in. One question I had was just a clarification: is the point you're trying to make with the set-up right after the time=Eulerian that material=Lagrangian? What does this have to do with covariant derivatives and total derivatives we spoke about last quarter? I have some notions, but I'd rather bring up the point of confusion so that you can tell everyone the right answer without me telling everyone a wrong one first.

Interesting question at the end of the lecture. I don't want to give away the answer to people who haven't read it yet, though.
