Problem Sets

We will have four homeworks, posted on Wednesday in the 2nd, 4th, 6th, and 8th week. The homeworks are due in two weeks time, on Wednesday by 5pm in the 4th, 6th, 8th and 10th week. Please put finished homework in a box marked 'Ph223b Inbox' in Bridge Annex. Solutions will be posted on this website. Graded problem sets can be picked up in a box marked 'Ph223b Outbox' in Bridge Annex.

You may take one full-credit one-week extension on a problem set during the term without question. Please indicate on your problem set if you are taking the extension. Otherwise, problem sets will be accepted for 50% credit up to 1 week late and after that not at all.

Presentation

There are no exams for this course. At the end of the quarter, everyone needs to give a 15 min presentation and write a short essay on a topic related to the course material. You can choose to work in pairs for this project. The topic should be discussed with me during the course of this class.

Grading

70% problem sets, 30% presentation.

Homework and presentation are governed by the honor system.
