Updates and useful bits
- → The last exam for the class will take place on Friday 12/7/12 (time/location TBD). The exam will only cover material since the last exam. This includes the following topics: x-ray crystallography, spectroscopy, surface plasmon resonance, NMR/MRI, and cochlear mechanics. In addition to the course notes (which should serve as your chief reference), some relevant Hobbie & Roth (4th ed.) chapters include: 18.1-18.5, 18.7-18.9, 18.12. Also for reference, posting some sample problems from 4090 Fall 2011 and their solutions. Note that for this test, you will be allowed to bring a single(-sided) sheet of paper containing any formulae and whatnot you believe will be of practical use. You'll be expected to turn this in with your exam.

- Problem (a la Polya):
A bear, starting from the point P, walked one mile due south.
Then he changed direction and walked one mile due east.
Then he turned again to the left and walked one mile due north,
and arrived exactly at the point P he started from.
→ What was the color of the bear?
