Space shuttle, what a machine!

What a great machine. Leaves orbit at 8:29 AM while over Indonesia, south Pacific, then lands safely 75 minutes later at Kennedy.



Nice.

More digital video of the hair experiments

Gabrielle and William defeat the Faraday cage.

Science experts William and Gabrielle find a way to defeat the Faraday cage in morning lecture yesterday.



Also in iTunes U. Excellent.

Homework

You guys have worked HARD this semester, and we are now looking good for a leisurely stroll through the last chapter of the semester, "Electromagnetism."

Therefore, by the power vested in me by the Sunshine State, I hereby declare:

Your homework this weekend is

1. Chow down with family and friends for Thanksgiving Day.
2. Reach out a generous helping hand to the needy or lonely.
3. ZZZZZZZZZZZZZZZZZ.

See you on Monday.

When the Boogeyman goes to sleep every night, he checks his closet for Chuck Norris.

HW ready

Make sure to look over the podcast when it is ready and/or the doc cam files for Nov. 23, before you tackle Homework 24. There are two brain burners.

Parallel circuit and the brightness level of the light bulbs

Another crude but effective video from yesterday.



Thanks to Gloria S. for operating the HD cam. Good work, Gloria!!

P.S. I will drop the videos into iTunes U as soon as I drive up to campus this morning.

Combo circuit demonstration video, various formats

Crude but effective high-def 1080p video from today's lecture demonstration is now up. First up: the series of two light bulbs. You can view the YouTube version here or the higher quality version in iTunes U.

1. "Demonstrations" which holds the larger format video, or
2. "Demonstrations-mobile" which contain the smaller file "mobile" version, which might be faster if you are on iPhone.

Exam 3 is UP.

I just uploaded your scantron scores for Exam 3. The score is out of 40, since we did not use CPS, only scantron. I will be working on the gradebook here in Webcourses so that you can see your "best two out of three midterms" subtotal.

CPS threshhold

Right now, if you have 99 CPS answered, or more, you are on track for getting 24/24 points on your semester grade. That means you could have missed 16 questions -- one pre-exam SMA review, or about 3 average lectures.

If you have 95 CPS answered, or more, by my rounding up method, you also will get 24/24.

At 94 CPS answered, you will nab 23/24 for your semester grade. In general, if you are below 99 right now, you must solve this proportion:

yay

Friday's lecture is up on iTunes U now.
