This calendar indicates what we will cover when, as well as upcoming assignments. It is updated frequently, but should always accurately reflect what will happen in the next week. DISCLAIMER: Some of the lecture notes are in farily raw form; they are often written in advance, and may not always reflect exactly what was done in class. I revew them before class, often making corrections and marginal notes. Such revisions may not be represented here.
