Week 3

Problem set 2 was due. This one was a also very similar to the questions we did in class. Considering each is only worth 1-1.8%, there is no reason why they should be hard, so that was good. In class, we discussed the principle of well ordering. I also bought the book, and found a really good explenation for all three of them: PSI, PCI, and PWO. We also did some more problems with trees. Received my PS#1 back, and was happy with the result.
