Course documents and handouts

Homework assignments


The project was assigned on Wednesday, March 17. It is due on the last day of class. See the project handout for more details. If you would like to do something other than (or in addition to) the suggestions in the handout, please come talk to me. When you have decided on a project group, please e-mail me to let me know.

Challenge questions


I am always interested to get feedback about this course: questions, comments, complaints, and suggestions. You are certainly welcome to talk to me directly. Otherwise, you can e-mail me, deliver a note for me to the Mathematical Sciences department office in Wean Hall 6113, or slip a note under my office door (PPB 342; make sure you mark the note with my name, since I have several officemates).
