The classroom computer crashed about 10 minutes into the lecture, so unfortunately we do not have a video. The lecture covered section 2.5.1 of the text, introducing conductors. Sorry about that. If you missed the lecture, be sure to read through sections 2.5.1 and 2.5.2 of the text, and have a look at the notes section labeled 2.5-Conductors.pdf. Important announcements: Homework 7 (first part due Wednesday) has been posted. Some of these problems will require serious thought; be sure to give yourself enough time to complete them. There will be a take-home exam covering Chapter 2 March 5-8. I'll probably make it due before class on the 8th, because I want to start chapter 3 in lecture that day.
