I now have six more math books in my room than I did yesterday. I’m so bad at resisting temptation when it comes to books. (I only had to buy two of the books, and of those two, one will be a textbook for next quarter, so I’m not as obsessive about buying books as I might have seemed had you glossed over the stuff in parentheses.)
Labutin got to use 2*2=4 as a lemma in a proof today. He said “Now using this lemma that 2*2=4, we can prove the theorem.” He failed to prove this theorem on Wednesday since he had made the assumption that 2*2=2.
For some reason, there’s a lot of furniture in the hallway of South Hall 6th floor. Maybe something is being done to some of the offices.
In music theory, we were subjected to a dreadful recording of the fifth Brandenburg Concerto. At least there was a harpsichord rather than a piano, but it was still dreadful.
We’re playing Beethoven’s Second Symphony, the first movement of Schumann’s Piano Concerto, the first movement of Mozart’s Violin Concerto in D, and Maher’s Kindertotenlieder. It seems like a very ambitious program given that the concert is on March 10th, but it will have to work somehow, and I’m sure it will.
There’s a concert tonight, and Beethoven’s Sonata for Cello and Piano in A Major will be performed. Yay!
Finally, here’s an interesting problem I thought of. Ryavec said it will be really hard. For which sets of points S in C with |z|=1 (z in S) is it possible to find a function f such that f is analytic on S and is not analytic everywhere else on |z|=1? I was thinking of functions centered at 0, but I don’t know how well that’s defined if f isn’t defined as a Laurent series.
