E-mail: : Please put PHY357 in subject line of any course-related emails. I will endeavour to reply as quickly as possible to your e-mails. 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.


11/05/06 All assignment and test solutions have now been unlinked from the web-page.

01/05/06 Assignment 5 has been graded and can be picked up from my office. The marks for all assignments and the class test are posted here , ordered by student number. All marks are shown out of 10. Please let me know if you notice any errors or omissions.

28/04/06 There is a mistake in the solution for 3b) on the current assignment. The radius should be 5.4cm, not 11.4cm (I seem to have entered 6418 instead of 641.8 in evaluating the final expression).

24/04/06 A brief description of the final exam is posted below

24/04/06 The solutions for assignments 4 and 5 are now posted. Let me know if you think there are typos or other problems.

21/04/06 I finalized the exam today. Over the weekend I will write the solutions for assigments 4 and 5 which I will post on sometime on Monday, along with some comments on the exam.

20/04/06 On question 1 of the assignment, the atomic mass number of the Se should be 82, not 85. Sorry about that......

13/04/06 It occurred to me after our review this morning that the one thing I did not list was accelerators; we also discussed linear and circular collider technologies. I may also have missed other topics. Just to be clear, any topic that we covered in the lectures may appear in some form on the exam. The review this morning was not meant to be exhaustive.

12/04/06 After saying that I would accept the final assignment without penalty until next Wednesday (April 19th) I realized that I have to be away on Tuesday and Wednesday next week. Since I will not be in my office to accept the assignments and since I don't want them shoved under my door, I will extend the deadline until 5PM Friday April 21. I will be in my office tomorrow and on Monday, and then back on Thursday and Friday of next week.

07/04/06 OK, the final version of the assignment is there. The new question should be pretty straightforward for those of you who attended the last tutorial. I know the typo in question 2. I just forgot to fix it..... the A,Z labels on Bi are upside down.

07/04/06 Apologies, I did not post the final question for the current assigment yesterday. It will go up this afternoon.

06/04/06 Lecture and tutorial notes from this week are now linked below.

03/04/06 I just noticed that I forgot to post the solutions to assignment 3. The link is there now. Sorry for the delay.

31/03/06 The preliminary version of your last assignment is now posted below. As stated on it, I will likely add a few more problems next week. The nominal due date is April 13, but I will take them without penalty until the following Wednesday at 5PM.

27/03/06 The overheads from today's lecture are now posted below, with the three corrections noted in class. I have also added links to some of professor Orr's lecture notes that I forgot to link (though I hope you all know where to find them), as well as a link to the overheads from the tutorial last week (previously just linked in an announcement).

27/03/06 Those people who received a rather low mark on question 1 of problem set # 3 (the one most recently returned) and feel it was unjustified, should go to see Teresa Spreitzer, the marker. Her office is MP 909.

24/03/06 I have to leave at about 2:30 today, so after that you can leave the assignment with our group secretary in Room 804. She will be in until about 5PM. Try not to cut it too close.

23/03/06 The mid-term test with solutions, is posted here . Hopefully they are not plagued with typos, but if you find any, please let me know.

Older announcements can be found here .

Course Progress ( Past Classes , Upcoming Classes )

PHY357 is normally taught by Professor Orr , who is on sabattical this year. It is a very popular course. For this reason, I do not propose to stray very far from the course he typically gives and in most cases I will use his lecture notes, which are available on the web (I will link them from here). That having been said, the outline below is provided only as a guideline. Things may shift slightly as the course progresses. We may tackle other topics, and I may do some things in a slightly different order, or take a different approach. As the course progresses, the entries below will be updated. As a guideline for upcoming classes you should consider this accurate only for the next 2-3 upcoming lectures.

Besides providing the lecture notes from the past few years, Professor Orr's PHY357 web page has a number of useful resources, such as old assignments and solutions. I encourage you to look at this.

Homework Assignments

Assignments are due at the start of class on the dates listed below. Each due date is a Thursday tutorial slot. I will accept late assignments only until the beginning of class on the following Monday, with a penalty of 10% per weekday.

As noted above, I will not accept assignments by e-mail.

Assigned problems will be posted two weeks before the due date. Solutions will be posted about a week following the due date.

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. If you cannot do the assigned problems on your own, you are unlikely to pass either the test or the final exam, which together provide the majority of your final grade.

Another problem that sometimes arises is that of legibility. It takes a lot of time to grade problems sets and it is very frustrating for the marker if assignments are messy and difficult to read. Please put some effort into ensuring that your work is clearly written. And please staple the pages of your assignments together.

Tests and Exams

There will be one mid-term test which will take place in class, and a final exam.

The test will take place in class on March 6. It will cover all the material up to and including the previous class on March 1..

The final exam is Tuesday May 2 9-12AM


The final exam has three parts.

Part A is worth 30% and consists of a single multi-part question. You have to do this question. For the rest of the exam you have some choice.

Part B is worth 45% of the exam. There are five problems of which you must do three. Each is worth 15% of the final grade.

Part C is worth 25% of the exam grade. There are four problems of which you must to one.

Finally, there is a bonus question worth an additional 10%. However, the maximum grade is still 100%.

You may have one hand-written double-sided 8.5" x 11" formula sheet, and a calculator. I've given you five pages of information, including most of what I think you will need for the problems on the exams, but (inevitably) not everything, so you will still need your formula sheets. I have given you everything that was provided on the mid-term formula sheet, plus a variety of other things such as fundamental constants, the periodic table, the shell-model energy level diagram and some other formulae.
