This Friday is the SELU CaPPS program. Basically, it is a program designed towards students interested in pursuing a career in physics or chemistry. There will be food and talks from people in graduate school and industry. I suggest you attend – it wouldn’t hurt.

I suggest you DO NOT look at the solution. Work as hard as you can. If you are still stuck, ask questions in class.
Here is a bonus post.
For those that missed it, this is a nice summary.
