Office: McLennan Laboratory 801 [Office Hours: Friday at 2PM, but you can try dropping by at other times, or you can make an appointment]
Phone: (416) 978-2950
Fax: (416) 978-8221
E-mail: N.B. Please put PHY489 in subject line of any course-related emails. I will try to reply as quickly as possible to your emails. However, I cannot promise that I will do so outside of normal working hours (Monday-Friday 9-5 for example). Please also note that I will NOT accept assigments via email.

Announcements (reverse chronological order)

Any announcements made outside of class time will appear here. I will do my best to also post any announcements that are made verbally in class. However, I cannot promise that this will always occur. It is YOUR responsibility to attend class or, if you do not, to ensure that you are aware of what was discussed, including issues not directly related to course material.

07/12/13 The solutions for assignment4 are now linked below.

03/12/13 Please remember to fill out the online course evaluations.

02/12/13 As announced in class (twice now) I will accept the final assignment without penalty until 5PM this coming Friday. No assignments will be accepted after that point.

25/11/13 The solutions for assignment3 are now linked below.

20/11/13 The problems for your last assignment are now posted below.

01/11/13 The problems for your third assignment are now posted below. Note that I have changed the due date from Nov. 13, to Nov. 15, since I was a bit delayed in posting this.

25/10/13 The solutions for the assignment2 problems are now posted below.

23/10/13 For Monday's mid-term there are four problems. You are expected to do all of them. You should expect a question on relativistic kinematics and one that requires the use of Clebsch-Gordan tables. You should of course know how to apply conservation laws and how to draw Feynman diagrams. The mid-term covers all the material up to and including the lecture on Oct. 16.

22/10/13 Most of you submitted your first assignment promptly, but I wanted to warn you anyway, that the latest I can accept assignment 2 is Friday at 5PM. This is so that I can post the assignment solutions prior to the mid-term.

22/10/13 I have uploaded new versions of this week's lectures, with some minor corrections.

22/10/13 I have had one person tell me about a conflict for the mid-term. Anyone with a conflict needs to notify me by email with an explanation of what the conflict is (e.g. what course; is the conflict with a lecture or another mid-term, etc.) as soon as possible.

20/10/13 The solutions to the first assignment are now posted below, in the homework section. Please note the comments on question 1. You will need login information to access these solutions. I will provide that in class.

09/10/13 The problems for your second assignment are now posted below.

04/10/13 Please see the following announcement from Accessibility Services, who are looking for a volunteer note-taker for PHY489.

04/10/13 The date, time and location of the mid-term are now posted below, in the Tests and Exams section.

18/09/13 The problems for your first assignment are now posted below, in the homework section.

Homework Assignments

Assignment due dates are given below and noted above in the Course Progress section. Late assignments will be accepted up to a week after the due date, with a penalty of 50%/week (10%/weekday) and a daily deadline of 5PM. Assignments later than one week will not be accepted. You can hand in the assignments at the beginning or end of the lecture period, or use drop box #1 in the Burton Tower stairwell (ask if you don't know where this is). Please do not slide assignments under my office door.

Solutions will be posted on a password protected web page. The username and password will be given out in class, or available via email (after the solutions to the first assignment have been posted).

A note on the problem sets.

I expect that, in the course of doing your assignments, you will discuss them with your classmates at some level. This is fine, and a normal part of the study process. What you most emphatically should NOT do, is copy answers from your classmates (or from anywhere else). It is fine to discuss the problems, but when it comes to actually writing out your solutions you should do this by yourself. To copy answers from someone else is an academic offense. But the more important reason not to do this is that you will not learn the material if you do not do problems yourself. It is quite possible to understand the approach to solving a problem, but still find that when you sit down to actually do it, you somehow can't get it to work out. The only way to really learn the course material is to apply it.

On another note, the problems in Griffiths are for the most part relatively straightforward. Most, but not all, of the assignment problems will come from the text, but I strongly encourage you, as part of your studying, to attempt as many of the problems at the end of each chapter as you have time for, and I am happy to discuss these with you if you find you are having trouble.

Problem Set Problems Due Date Solutions
Problem Set #1 Posted 18 Sep Oct. 2 Posted 20 Oct.
Problem Set #2 Posted 09 Oct. Oct. 23 Posted 25 Oct.
Problem Set #3 Posted 01 Nov. Nov. 15 Posted 25 Nov.

Tests and Exams

The coursework will consist of four problem sets, one two-hour mid-term (outside of lecture time), and a final exam.

The mid-term will take place from 5-7PM on Monday, October 28, in room BA 2155 (in the Bahen Centre).

Information on the final exam will appear later in the term. The date and time will be available from the university exams website .
