## Welcome to Physics 227    Autumn 2012

### Elementary Mathematical Physics

Prof. Steve Sharpe

MTWTh 11:30 - 12:20 in PAA A110 (MTTh) and A102 (W)

• 12/6/12   Here is the link to the Physics 228 web site.
• 12/14/12   Solution to final posted on "Quiz and Exam solutions" link. Typo is now corrected.
• 12/15/12   Scores on final, total score on course, and course grades are now available on GradeBook.

Total score was obtained as follows:
HW=Sum of HW scores/Max possible, Q=Sum of quiz scores/Max possible
M1=midterm 1 score/50, M2=(midterm 2 score+4)/50, F=final score/100
(score on 2nd midterm increased by 4 since test was harder & average lower.)
EXAM=Max(Qu+M1+M2+F, Qu+M1+2*F, Qu+M2+2*F, M1+M2+2*F)/4
(i.e. dropping lowest exam score with final "counting double")
Total_Score=0.1*HW+0.9*EXAM
Grade = 2.0 + 2.0*(Total_Score-0.46)/0.5 (rounded to nearest 0.1)
(so that Total_Score=45% => 2.0 and 95% => 4.0)

• 12/15/12   If you would like to get your final before next quarter, please email me and we can try and set up a time for you to come to my office. I will only be sporadically available over the break.

Have a great break!

## Texts

• Our required text is:

"Mathematical Methods in the Physical Sciences," (3rd Edition, Wiley) by Mary L. Boas.

We will follow the ordering of material in this text, and draw most homework questions from it. Corrections to the text are available here. Note that solutions to some problems appear at the back of the book (and there is a companion volume to the previous edition which contains solutions to approximately 1/4 of the exercises, many of which are the unchanged in the current edition).

## Course Organization

• This course, together with the subsequent PHYS 228, aims to provide you with the mathematical tools needed to master physics at the UG level and, to a significant extent, at the first-year graduate level too. We will cover a lot of material, with some of which you may have some prior experience, but most of which is likely to be new. We will move quite fast, and it is imperative that you are organized and stay on top of the material. This means practice, practice and more practice. Weekly homeworks provide a minimal level of practice, and will include suggestions for additional problems not to be turned in. Weekly quizzes provide incentive to stay on track.

Basic use of computer mathematics programs is an integral part of this course, including some parts of lectures and some homework questions. You may use Mathematica, Maple , Matlab or Python. Mathematica is available on all the PCs in PAB B101 and the study center AM018. In addition, students can now install Mathematica on their personally owned computers at no cost. See here or here for information about obtaining it, Brief instructions on getting started with Mathematica are here.

I keep a log of what has been covered, together with my lecture notes, on the daily coverage page. This will also indicate any material not covered in lecture that you should read.

• Holidays.
• There will be no classes on Veteran's day (Monday, Nov. 12th), or Thanksgiving (Thursday, Nov. 22nd).
• Homework.
• There will be weekly homework sets, due on Tuesdays by the end of lecture (starting in the second week). I will bring a box to class; they can also be placed in my mailbox in the physics office (but only until 12) or under my office door (until 12:30).
• Each HW set will cover the material discussed in class the previous week (as well as any extra assigned reading).
• You are encouraged to discuss the assignments with classmates, but the solutions you turn in must be your own work.
• Working on assignments in a timely fashion is a crucial part of the learning process. Late assignments will only be accepted by prearrangement, and only under exceptional circumstances.
• Solutions will be posted on the HW link after class on Tuesdays.
• Selected problems from each HW will be graded.
• Regrade requests must be made by the end of the class session following that in which the HWs are returned, and must be made in writing on separate sheet of paper which is attached to the HW. There should be no additional writing on the HW itself.
• Quizzes.
• There will be weekly quizzes in class on Wednesdays, except in weeks in which there is a midterm. The quizzes will take place in the large room A102.
• The quiz in the first week ("quiz0") will concern background material and will not be graded.
• Starting in the second week, quizzes will concern the material discussed in class the previous week (as well as any extra assigned reading), and thus will be based on the same material as the HWs turned in the previous day.
• I expect the quizzes to take up about half of the class time.
• Regrade requests for quizzes follow the same procedure as for HWs.

## Exams

• There will be two midterms and a final exam.
• The midterms are scheduled for Wednesdays October 24th and November 28th at the usual lecture time, but in the room next door, A102. This is a much larger room than our regular lecture hall and so will allow you to spread out.
• The final exam is on Wednesday, December 12th from 2:30-4:20pm. This will also be in our regular lecture room plus one or more additional rooms that I am trying to organize.
• If you have to miss an exam due to a UW sponsored activity (e.g. travelling for a sports team) please contact me ASAP.
• Exam rules will be discussed in class and posted on this web page closer to the exams.
• I expect to spend part of the lecture period prior to each exam on a review.

• First note that to pass the course, you must take at least one of the midterms and the final .

The course grade will be determined by scores on quizzes, homeworks and exams as follows. The homeworks will count for ~10% (the "~" indicating that, since this is the first time I have taught this class, I may make some minor adjustments to the weight given to the homeworks). The remaining ~90% will be determined in equal part by the quizzes, the two midterms and the final, except that the final will count double and that the lowest score will dropped. If the final is the lowest score then only half of its score will be dropped.

This policy means that you are not penalized if, e.g. for personal reasons, you miss a midterm. This allows me to enforce the policy that there are no makeup exams.
