1 Physics 212 (welcome!) Instructor: Chris Coffin Wngr 283

1/4/16Oregon State University PH 212, Class #12 Announcements ･ For all registration issues, please go to the Physics Office (Wngr 334). Unless you have prior permission, do not attend any class other than those you’re registered for. ･ No labs meet this week. You will first meet your lab TA next week. (If you have the PH 222 recitation, that course will meet this Thursday.) TA names and schedules will be posted soon. ･ Get your textbook. You’ll need either the full hardcover (Knight 3 rd ed.) or Volume 2 of the custom OSU edition. You don’t need to buy a lab manual—all labs will be posted online. ･ I expect to be using clickers starting this Wednesday. If you don’t already own a TurningPoint clicker, you’ll need one.

1/4/16Oregon State University PH 212, Class #13 All About This Course 1.Read the web site. Start with the Announcements and go from there. The Lab 1 take-home assignment will also help a lot—get started on that right away. 2.Keep pace! Use the Course Calendar to guide you. There are a lot of topics this term—and with no more than a week spent on each major set, you’ll really get lost if you get behind. There is quite a variety, and we skip around in the textbook somewhat. 3.Last term’s PH 211 site is still all posted—use it as a guide and “refresher” as you need it. In fact, the first three weeks of this term are directly analogous to most of last term….
