Class Information

Course Materials

  • Textbook: The textbook will be David Griffiths' Introduction to Electrodynamics 4th ed. (I believe you can find cheap copies and pdf's.) Here's the Amazon link.
  • Some way to write/sketch to share with me and the Class
    • Tablet? The STEM Center has some available, and I believe Physics does as well.
    • Your phone zooming in using just your finger?
    • A physical whiteboard? We have to test if I can see it. And also, this doesn't allow peer collaboration on same space.
  • Annotating things (related to above)

Recent announcements:

  • We won't meet live this Friday, 10/26. It's our no-break-fall-break. I'll record a lecture and post it to Slack.

I *had* been planning to keep all course content in Moodle

But given all y'all's reaction, I'll keep it here. Here's a link to moodle page
