Thursday's lecture = GO

We will have regular lecture on Thursday morning, back to the normal schedule.

Thursday's lecture will be on gravitation, so do some reading and skimming in chapter 5, if you have 30 min. Especially look at the diagrams and illustrations. We will review and elaborate the blurb on p. 81, "Working it out|Gravity" plus some of the exercises on circular motion and orbits from chapter 4, p. 73:

1. exercise 8, generic circular motion;
2. exercise 9, Earth-Sun orbital system;
3. exercise 10, Earth-Moon orbital system.

You can eyeball those tonight and maybe bug Ashton and Meg with questions in Discussions. :)

See you Thursday morning, GO FOR LAUNCH!

Enigma machine

Ashton, our early class TA, has set up a new Enigma machine as an extra study workout on rotational concepts and ideal gas model ideas. Click the Enigma icon (right) to try it out.

Ashton the T.A. now will have office hours

You guys in section 0001, 9:30-10:20 AM, can check in with Ashton, our mighty T.A., during her office hours. She will announce them in the Webcourses discussion area, "Ashton's Annex." I think whe will have hours Tuesday, Oct. 2nd, in the afternoon. Please look in Ashton's Annex for the exact specs.
