My Circuits professor likes to assign us problems with variables. As an example, his lecture on Kirchoff's Laws and his homework mostly involve us deriving equations for various things using only variables for voltage and resistance.

I need a good reference on how to solve linear equations using matrices. And on how to take the determinant of matrices above 3x3 with variables (and without LOSING MY DAMN MIND, good grief, that last attempt took me forever and I didn't even finish.)

(I at least hope he posts a detailed answer to this homework question! Because I'd love to know how he used Kirchoff's Laws to derive the equation he asked us to derive. I could easily do it by finding equivalent resistance, but that's not what he wanted. :/)

First week of summer school is done, and it's not moving as quickly as I expected it to move.

I really wish I hadn't had to take another music appreciation class, but at least the professor is cool about it. He usually lets us out early, which feels a bit odd on a five-week class. He's a silly, likable guy, at least. (He called Bach a "B. A. Mo-fo" in class. Exact words.)

Discrete Math is... strange. At least I already know something about proofs; only half of the class does. The professor said that most Geometry classes stopped doing proofs when they had too many classes to teach, because it takes too long to grade them. Also, pretty much everyone in the class is studying computer science, which means I'm probably meeting a bunch of my classmates here.

I'm walking almost two miles a day on weekdays, thanks to school. I wish I had more chance to rest between walks, but I think it's helping, either way.
