  In the case of the QM problems, the big problem was failure to find all the cases.
- Your project revisions have not been graded yet -- sorry.
- Final:
  - Monday, 12/12, 6:45 - 8:45 p.m
  - For the final you may have an 8.5x11 page, both sides.
  - Some old finals
- It is time for course evaluations: please visit eval.nku.edu to give your feedback (and also to make sure that you will get access to your grades earlier).
Today we'll
- start with questions, over anything in the course.
- Then (presuming there's still time) I'll present my "big example", from Lewis Carroll:
  1. Babies are illogical.
  2. Illogical persons are despised.
  3. Nobody is despised who can manage a crocodile.
  What can we conclude? First of all, from The Once and Future King: all that is not expressly forbidden is mandatory.
  Solution:
  - Logic: In particular, can babies manage crocodiles?
  - A Truth Table (of logically consistent possibilities)
  - Using Venn Diagrams to illustrate possibilities
  - Carroll's "Logic Game" method (which is essentially the Karnaugh map)
  - Simplification
  - An expression tree and a logic network
