The UCSB bookstore doesn’t know what it’s doing. The textbook for differential topology costs $40 or so downstairs in the textbook section and $30 or so upstairs in the Springer math book sale section. Fortunately, I realized this and saved myself some money.
Jon, Jeff, and I did a bit of algebra today. We got through most of Tuesday’s lecture. Math is hard, but that’s a good thing.
It’s so cold here. Weatherbug tells me it’s 46 degrees Fahrenheit. Isn’t it supposed to be warm in Southern California?
