This week, we will have a different format for the homework, which is out of
   four marks. The intention is to reduce the work load a bit while promoting
   interesting classes.

   All you need to do is E-mail me roughly four non-trivial suggestions for the
   class sessions, ideally including volunteering to do something about it
   (examples below). 

   I will bounce your mail to the presenters who will grade them largely based
   on how useful they were to them in the task of leading a good class. 

   Material for the first half of the chapter needs to arrive relatively soon
   (Monday night at the latest) in order to count.  In other words, if you send
   material after Tuesday's class it needs to take into account what we covered
   on Tuesday (but could extend it). 

   The scale is roughly one point per non-trivial suggestion. If you have small
   items, you could batch them up. 


   Examples follow: 

   1. You could either do a problem from the book, OR create your own problem
      (e.g. fill in some details, implement something), and volunteer to lead
      the discussion of it on the board.

   2. You could look up some part that you did not find very well done in the
      book, and volunteer to report what you found.

   3. You could write about a particular item / concept that you want to
      discuss. But---explain what you understand about it, and where you have
      run into trouble. If your questions are relatively "short", you could
      batch several together. It will be assumed that you will ask this
      question when the time comes.  

   4. Your idea goes here.
