I would prefer it in physical form, rather than in email. The topic is up to you. It should be on some issue or issues in Artificial Intelligence, either directly related to one of the ten readings, or relevant to those readings. Original research is not necessary. It is fine with me to rely solely on the ten readings.
Original thoughts is more important than original research.
Look over the readings, and think of which ones engaged you most deeply, on which topics you have the strongest opinions, the most original thoughts. A thoughtful rebuttal of a single reading would be fine as a topic. So would exploring any topic more deeply, either through the links on the syllabus, or via a Web search. About the only thing I don't want is a summary of one or more readings, unless in a concise form to pave the way for your own argument. I will be at a meeting at Rutgers on May 10th and 11th, returning late afternoon the 11th.
