Educating your mind

For those of you who are using advanced study techniques to prepare your coconut for Wednesday's midterm exam, I just posted some extra blurbs in the Doc Cam folder.

1. Optional reading on the orbits of the gravitational field, many cool looking diagrams, and
2. for Friday's lecture, a pair of biographical blurbs on Edmond Halley and Isaac Newton.

If you have some extra time, you can look over the orbits pages.
