Come to his talk, if you can, for extra credit! (equivalent of a homework assignment). If you can't make the talk, you can earn extra credit by writing a report about one of his articles on the web (two pages, due Monday). They are available from the Science News homepage (do a search on Mathtrek).
It has been brought to my attention that the articles are so short that it's hard to get two pages out of one. Combine two articles then! Or find additional resources on the web, etc., related to the article. Don't just increase the adjective count, however!;)
