"Let me repeat..."

I frequently use the phrase, "Let me repeat that..." in order to emphasize an important concept for your lecture notes.

There is a new discussion area in Webcourses on which to re-post the information from lecture that I repeat with that phrase.

Post it there. Ashton and I will read and double check and maybe even give a bonus point or so if it is well done and timely. It will also be a good study tool after a few lectures.

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!

BONUS points questions for exam 3

Last discussions announcement of Fall 2007

There is a new set of discussion areas in Webcourses, prep for midterm exam 3. One discussion area is for chapter 8 angular momentum concepts and another is for chapter 11, 12 and 13 concepts on the states and properties of matter.

A third discussion area is "BONUS points questions for exam 3" and I have already posted a sample question there. 2 bonus points for you if I choose your question!

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.

If you took notes last Wednesday...

If you took notes on the CPS questions from last Wednesday, Sept. 19, please post the questions in the discussion area called "CPS, Wed., Sept. 19," and this will help me sort out the trouble with CPS scores last Wednesday.

If there are more than two or three postings already, with the same questions you have, then you do not need to post. I will lock the discussion after a few students post. Gracias!
