Physics 1120, General Physics 2: Electricity, Magnetism, and Optics
Instructors: Steven Pollock and Victor Gurarie
Not everything obeys Ohm's Law. The soccer ball shaped molecule C-60 can be used to build a crystalline solid that is a
superconductor. People keep finding ways to make it superconduct at higher and higher temperatures, which may some day be big news for physics.
Week 6 Highlights:
Lectures this week on Electric Currents and circuits.
Reading:
Chapter 28 (currents) and starting on Ch. 31 (circuits)
Special notes: 
- We have an 1120 CULearn page. Your grades are there (as of the first midterm, it's not "live". I'll update it after each midterm). If you have a zero for "clickers", maybe you haven't registered your clicker yet? Don't forget to do that, and it must be for the correct lecture (10 AM or noon!)
- Our CULearn page also has a "threaded messages" list - please ask each other questions about the course, even (especially!) homework there, and respond to one another. It's great for you to ask questions, give and get help about the problems, give hints. Use it as a resource to collaborate - if you feel comfortable knowing that I'll be reading it, then what you're posting is probably fine!
- "Virtual office hours" link is where I post
email questions, if I think they're of general interest.
