Please fill out the introduction survey: Section 105, Section 109
General
GSI: Marcus Bintz, mbintz@berkeley.edu
Office hours: Tuesday + Thursday 10-11 AM, LC 107
Time + Location:
- 105: 4-6 PM, Monday (LC 245, Lab) and Wednesday (LC 200, Discussion)
- 109: 12-2 PM, Tuesday (LC 245, Lab) and Thursday (LC 226, Discussion)
Recommended textbook: “Physics” by Resnick, Halliday, Krane (5e has better problem layout than 4e, but both are good. NOTE: not “Fundamentals of Physics” by Halliday, Resnick, Walker)
7B course info: Course policies, syllabus, 7B section policy
The primary goal of the discussion sections is to develop your problem-solving skills, and each will be split roughly in half. In the first half I’ll walk through problems on the board, and possibly review material from lecture or present a different perspective on it. For the second half I’ll provide a set of problems you can work on in small groups, while I float around the classroom to help.
Section problems will be posted here at the start of the week, and their solutions at the end of the week. My go-to source of problems will be from the recommended textbook (“RHK”) – the difficulty is intended to be similar to what appears on the exams. I will upload recommended readings from the 5th edition of it (and maybe other sources) here as well.
