Notes about the videos

  1. newTHERE IS A VERY IMPORTANT ANNOUNCEMENT BELOW. CLICK HERE TO SEE IT.
  2. New videos, after 9/24/2009 should have good sound. Earlier in September, I had to used a wired microphone. In August, I used the planetarium wireless microphone which had some significant sound problems.
  3. If you notice any problems or abnormalities, please let me know. For example, there have been times when I forgot to turn on the microphone and didn't notice.
  4. Some videos that you might expect to be available may be missing because of technical difficulties. Sorry.
  5. For students, please consult your notes or the teacher version of the PowerPoint if you can't read what's on the screen. See the PowerPoint page.
  6. Here are videos from Spring 2009, Fall 2008, and Spring 2009.
