I returned the Music textbook/CD set that I mistakenly bought and got enough money for the correct Music text and my Russian text/cassette set and then some. Of course, I had to wait for much time in line to do that, and also to obtain my Logic reader.

Logic really does boggle the brain. I have to read 31 pages by tomorrow and it took about 90 minutes to an hour to read and comprehend {a nectar, about twenty}. So I still have to finish that, AND music AND Russian. Argh.

Sometimes wrapping my mind around Logic concepts takes a while. It takes practice to remember/comprehend, for example, that "if p then q" is equivalent to "p only if q," but I have it almost down now. And I thought there was some inconsistency in the text where the author said "this is an inclusive or" and then used "either," which implies an "exclusive or" relationship, but then I went to Professor Warren's office (he's the type who's in his office even when it's not his Office Hours, as I'd hoped) and he explained that I'd hit on something important, and that the author believes that "either" really just clarifies internal groupings within statements and doesn't denote exclusive-or-ness.

I'm so glad I've been reading Hofstadter. GEB has helped me get a head start on logic, and I hope to finish it in the next week or so. Yeah, right, what with moving, and with helping my mom clean this weekend.

I've been humming do-re-mis all day, too. I've almost mastered do-ti-la-sol-fa-mi-re-do, and can sing do-mi-sol and do-mi-sol-mi-do without too much difficulty.
