Note sheet art contest winners:

There were a lot of good note sheets. Here are some of the ones I liked best (and some of these are now up on my office door). I've put all the note sheets in the black boxes outside my office; if you'd like to reclaim yours, you're welcome to come get it (including if it's on the door!).

This one gets an award for best general artistic conception. (The sketch didn't come across so well on the scan; you'll have to stop by my office door to appreciate its detail.)

This one gets an award for the best illustrations and best embedded math jokes.

This one gets an award for best approximation of modern art.

This one gets an award for most festive organizational borders.

Finally, this one gets an award for the smallest writing (and has a bonus design element, too).

Final Exam Info:

The final will be on Wednesday, December 14, 11:30am-2:00pm, in O'Neil 123 (the usual classroom). There will be review office hours on Monday, December 12, from 11:30-1:00 pm, and on Tuesday, December 13 from 2:00-3:30 pm.

You will be allowed to have one side of one 8.5 by 11 sheet of notes for the exam. All sheets must be handwritten. You can write anything you like on the sheet -- formulas, examples, mnemonics, funny sayings, etc. No magnifying devices allowed. For those who would like to decorate their sheets or otherwise artistically arrange them: I will post my favorite ones on the course website after the exam. I also may post some of them on my office door, where they will live in glory for an undetermined period of time.
