First digital lecture now available

I just put out the first lecture. It's split into 4 videos (1, 2, 3, 4), and there is also one pdf file that contains all `black boards' that have been produced during these recordings. Everything that is covered here will be discussed on Monday, March 30.

In the future, I will follow the same format and try to put out 3-4 videos of up to about 20' length, along with a single pdf file covering the whole lecture. The lectures to be discussed on Mondays will be put out on Wednesday or Thursday, those to be discussed on Tuesday on Monday afternoon. You can always find these files directly on the course homepage (below the section with the problem sets).
