Hi everyone!

No homework 12 so you can study! Midterm 2 will cover the material on
	- 2-Body Central Force Sytems & Scattering
	- Rotations : Inertia Tensor, Euler Equations, Euler Angles
Go back through the problems from lecture, discussion, homework, and textbook 
examples. Morin's textbook (online at the library, see the INFO-General file) 
provides a huge source of additional worked problems on both of these topics. 
Also don't forget to simply REVIEW the subjects, so you impose some STRUCTURE 
on the material in your mind. 

Two old midterms are in this folder with solutions in the secure folder. 
Please note that I did not cover Euler *Angles* in those previous midterms
but we did a good job of them before Thanksgiving this semester 
(yay! rotational Lagrangian!) so they will be fair game on our Midterm 2. 
Oh and before you ask : no, there will NOT be any GR or anything from
Midterm 1 on this exam.

Cheers! Naomi

P.S. Always try problems BEFORE you look at their solutions, and 
do consider simulating the time constraints of an exam: practicing how 
to solve questions efficiently under time pressure is definitely useful.
