Day off from lecture

I think that nearly everyone worked their you-know-what off to get ready for midterm 3, so I am giving everybody the day off from lecture.

In the meantime here are a few things you can work on:

1. Scout ahead in the textbook:
   
   17. Light
   20. Electricity
   
   I specifically like the "Physics On Your Own" blurb on p. 341, with two pencils and a small mirror. You can try this out. And if you have another small mirror or two, you can make your own retro-reflector like the Apollo astronauts placed on the moon, which is diagrammed on p. 344.


2. View the two new movies on the Uvision site, both about the electromagnetic interaction, our last big topic of the semester.

See you again on Monday!
