8.04 Quantum Physics I
Spring 2014
Instructors: Matthew J Evans, Liang Fu, Mark Vogelsberger, Ross Corliss
TA: Paolo Glorioso
Lecture: TR11-12.30 (6-120)
Information:
Who Should Take 8.04
8.04 is a first introduction to quantum mechanics aimed at students
with a good grasp of newtonian mechanics, E&M and waves at the
level of 8.01, 8.02 and 8.03. While the topic is not hard,
developing an intuition for quantum phenomena demands concerted
effort.
Prerequisites
Students registering for 8.04 must have completed 8.03 (or 6.013)
and 18.03 (or 18.034) with grades of C or higher.
Exceptions to this policy will require the explicit
permission of Prof. Evans before the end of the first week of
classes.
Stellar Web Page
All course-related documents (such as the syllabus,
problem sets and solutions, practice exams, announcements) will be
distributed electronically via the course webpage. Students should
check this page regularly for updates and announcements. Students
can also send comments to the teaching staff anonymously, using the
form provided on the web page.
Grading
Grades can be viewed using the secure Gradebook
link (sidebar).
The final grade for the course will be based on the following
equation:
Final Grade = Exam
Average * ( 0.9 + 0.2 PSet Average
+ 0.05 Clicker Average )
The exam average will be 50% Final and 25% for each mid-term
exam.
For example, if you ace the exams, you will get an A even with low
scores for your PSet and Clicker averages.
However, if your Exam average is low, a strong PSet average can
bump you up by a letter grade or more.
If you answer most of the Clicker questions, you could get nudged
up further, eg from a B to a B+.
Note: Requests for re-grading of
homework or exam problems must be made within 7 days after the
assignment/exam is handed back in recitation.
Clickers
Several classes in physics and other departments use an interactive
response system to ask students questions during class. Students
enter their answers using an RF response card made by Turning
Technologies. Each student will need to buy one of these
"clickers", which will be available at the COOP. These
units can also be used in other courses at MIT, and the COOP will
offer a buy-back program.
Once you have bought your clicker and know your recitation number, please enter the ID of your clicker here.

Final Exams and Grades
Final exam scores and grades are now in the gradebook!
Please take a look, and if you think that something went wrong in the grading let me know ASAP.
Remember that the calculation done internally by the gradebook is NOT the one used to generate your grade. Your grade is generated based on the scheme on the 8.04 Stellar page:
Final Grade = Exam Average * ( 0.9 + 0.2 PSet Average + 0.05 Clicker Average )
The cut-offs were A < 90 < B < 79 < C < 65 < D < 56 < F .
(For the record, 88-90 is B+, 106-115 is A+. I didn't do B- or A-.)
Best of luck and a great summer to you all!
It has been fun,
Matt

Study Material
I have uploaded some material that may be of interest to you.
1) long answer practice questions, and solutions
2) clicker questions from lecture 23, with answers indicated
3) PS11 solutions
4) Exam 1 solutions
5) the formula sheet for the final
6) Prof. Weiss' lecture slides (will not be on the final)
Also, Prof. Vogelsberger has posted solutions to his "Quick Control Questions III" (good thing too... these are hard!).
And, of course, all of the lecture notes and psets are there for your reading enjoyment!
Best,
Matt

Optional Pset 11
The 11th and final problem set is now online.
This pset will not be graded, so there is no need for you to hand it in.
Keep in mind, however, that problems of this nature may appear on the final.
On Tuesday we will talk about EPR and Bell, and spend some time on clicker questions.
Thursday, the last lecture, will be an EPR demo by Prof. Rai Weiss.
Best,
Matt

Neat, plausible, and wrong
The non-proof given at the start of lecture was an “Evans Special” which I thought was easy and neat, but turned out to be incomplete. My thanks, as always, to the students who fearlessly highlight my blunders. =)
“There is always an easy solution to every human problem–neat, plausible, and wrong.” - H.L. Mencken
The lecture notes are now posted, and they contain an IES proof (Improved Evans Special). This one might even be right!
(The notes also contain references to chapters in 4 texts, each of which does the same proof a bit differently.)
About the promised pset: I have yet to decide if I can make something that will be useful, but I will try. This last pset, should it come to exist, will NOT BE GRADED. (The idea is to give you a study tool for the last week worth of lectures so that you don't see your first perturbation or spin problem on the final.)
I hope you all enjoy the great weather!
Best,
Matt

Exam 2 Grades - Doh!
As all of you have certainly noticed, I should have said "in recitation on Wednesday", since Tuesday is ALSO a holiday!!!
(Wow... 2 extra days off and no 8.04 pset... think of the possibilities!)
Enjoy the long weekend!
