I have updated the course ¡­

I have updated the course web pages today, so please check out the schedule for the next few weeks and information regarding Obligatory Exercises. Also, until the very end of the lecture today, we thought obligatory registration of presence would not happen today, but actually it did, as people were leaving the room. If you left class early today or were unable to participate today, please make sure to re-register for this class. There are spaces available, and on-line registration will be open starting tomorrow. Finally, please note that our first laboratory session will be this coming week (Friday, February 5).
