Lectures: This quarter I am the main lecturer for both sections of Phys 121. Lecture times for Phys 121A are M,W,F from 1:30 to 2:20 pm in PAB 118, and for Phys 121B from 2:30 to 3:20 pm in the same room. Please attend your own section since the "clickers" (ITT remotes) are keyed to a particular lecture class list.

Labs, Tutorials: You should be registered for a lab section (Phys 121Z...) and a tutorial section. Both have mandatory attendance. All lab information is available at http://faculty.washington.edu/storm/labs117_121/index.html. The link to the tutorials homepage is

Office hours by Instructor: Normally on Wednesday morning from 11 am to 12 noon in office, B-445, Physics Astronomy Building, and on Thursday afternoon, from 3 pm to 4 pm in the Study Center. Other times around exams will be announced in class

February 9. Sone notes about Exam II have been posted, please go to Exams.

January 27. Exam 1 has been graded. You can access your score from the Tycho website (the same one for the homework problems). The median score for both sections was almost identical, around 67-68 points. You can access the class distribution through the Physics Department web page, go to Academics, Courses, Phys 11X and 12X, then Phys 12X Winter 2006. Once on this page, scroll to the bottom of the page and click on Exam Statistics, then click on Phys 121A or 121B first exam. A bar graph with mean and standard deviation will be displayed, bunched every five points.

Exams will begin to be returned in classs on Monday. A simple method is to put exams on tables at the front in alphabetical order. If you DON'T want your test put at front, but rather received from me directly by hand, please send me an e-mail and I'll pull them out of the stack. The white cover with your name and student number will be the only thing showing. No grade is printed on the cover sheet.

I will scan the picture/question with which I finished class today, but probably not until Sunday (I don't have a scanner at home). It was essentially problem 67 from Chapter 5 of the book Physics by Halliday and Resnick (the text used in Phys 12X honor's section). The question is "what is the free body diagram" for the platform (not the person).
