Discussion: 9:00 - 9:50 am Wednesday RH 108

Grading : Lecture notes are posted on the web.

Goals: To understand the concepts and the equations that describe the theory of introductory quantum mechanics.

Huh? Please feel free to ask questions in class. If you don't understand something, it's probably because I'm not explaining things well and therefore lots of other people are confused as well. So if you ask questions, you'll be doing everyone a favor.

Required Textbook:

Course Web Page: Course materials such as the syllabus, homework assignments, and lecture notes are available on the course web page (http://eiffel.ps.uci.edu/cyu/p61A/class.html). There is a link from eee.uci.edu

Lecture Participation and Clickers: We will use clickers during lecture. This will contribute 5% of your grade. To receive full credit starting with week 2, you are required to answer at least 75% of the questions asked in lecture using clickers. You will not be penalized for incorrect answers. You may purchase clickers at the UCI Bookstore. Batteries are not included, so you will need to purchase those as well. You will need to register your clicker at http://www.iclicker.com/support/registeryourclicker/ in order to associate your clicker number to your ID number. If you registered your clicker last quarter, you will need to register it again since information from previous quarters is not saved.

Lecture Courtesy: Please show basic respect and courtesy to others during lecture. Cell phones should be turned off during lecture. Idle conversation, eating, reading the newspaper, text messaging, or using your laptop for any purpose other than taking notes is distracting and discourteous. If you arrive late or must leave early, please take a seat on the aisle near the door to avoid disturbing others.

Administrative Matters: Most administrative matters such as enrollment can be handled by going to 4109D FRH which is open Monday through Friday from 9 am - 12:00 pm, and 1:00 - 4:00 pm.

Enrollment: Enrollment add/drop changes can be made using WebReg or StudentAccess on the www.reg.uci.edu website. The deadline is Friday, January 17, 2014. No adds will be allowed after January 17, 2014. Students who wish to drop a class or make a grade change after January 17 should do so in person at the Physics Undergraduate Affairs Office in 4109D Frederick Reines Hall. Extension (ACCESS UCI) students should see Eileen Powell in 4109D FRH on Thursday January 16 to sign up for the course.

Homework: Homework problems are assigned for each chapter. All homework assignments are due at the beginning of class on the due date. Late homework that is turned in within 24 hours of the deadline will be given half credit. No homework will be accepted after that. The maximum score for each problem set is 10 points.

Physics involves problem solving. The best way to learn physics is by doing problems, not by memorizing formulas or reading the book over and over without thinking. Michael Jordan did not become a world famous basketball player by reading more basketball books than anyone else. He did it by practicing basketball. Same with physics. You have to learn by practicing solving problems.

Discussion section in-class problems: Each week in your discussion section you will be given 2 problems to solve in class. A preview of one of the problems will be posted on the course website earlier in the week. Each problem will be scored with a 0, 1, or 2, depending on the level of comprehension of the solution. So the maximum score each week is 4 points. You are strongly encouraged to work in groups, and may refer to your textbook and notes. Your TA will be available to provide help. In-class problems will be collected and graded. No make-up in-class problems will be given. A score of zero will be given for a missed discussion section. Your lowest score will not count. You must work on the problems and given them to your TA in your assigned discussion section; otherwise you will receive a score of zero. Graded problems will be returned in discussion section.

Scores: Scores will be available on the internet (http://e3.uci.edu/toolbox/gradebook). You should check to make sure these have been correctly recorded.

Answers and Solutions: Solutions to the homework and discussion problems will be posted on the web by Thursday of the week when they are due.

Exams: The Midterm exam will be given in class on Thursday, February 13 (RH 108). The Midterm will cover chapters 3 through 6. The 2-hour Final exam will be given on Tuesday, March 18 from 10:30 am - 12:30 pm in RH 108. The Final will be comprehensive and cover chapters 3-10. All exams will be closed book. Calculators are allowed but you are not allowed to store any information in electronic media such as calculators. You must bring picture identification to both exams. No cell phones or backpacks are allowed; failure to comply will result in a score of zero on the exam. If you bring these items to the exam, they must be deposited at the front of the room during the exam.

Calculators: Only the following nonprogrammable/ nongraphing calculators will be allowed during exams. Note that solar powered calculators may not work in the lecture hall which is quite dark in some places. No other electronic devices of any kind (cell-phones, pagers, PDAs, etc.) are permitted. Use of any electronic device other than an approved calculator model during an exam is cheating.

Cheating and Academic Dishonesty: Anyone caught cheating on an exam or in any other aspect of the course will automatically fail the course. In addition, the appropriate deans will be notified. Cheating includes giving or receiving assistance on an exam. If you are caught in possession of another student's iclicker, or if you are caught with more than one iclicker, or if someone else is caught in possession of your iclicker, your actions will be considered cheating.

More generally, anyone involved in academic dishonesty will automatically fail the course. Academic dishonesty includes, but is not limited to, copying or providing answers on exams, use of unauthorized notes or other materials on exams, altering graded problems or exams before requesting regrading, obtaining unauthorized copies of problems or exams, lying to excuse an absence, or any other form of dishonesty or cheating intended to unfairly improve your grade. If you have any doubt about whether some behavior constitutes academic dishonesty, first, assume it does, and then ask the instructor or your TA to be sure. Please see the University's official policy at http://www.editor.uci.edu/catalogue/appx/appx.2.htm for more details. If you become aware of cheating, please contact the professor or the TA as soon as possible, and we will follow-up while ensuring your anonymity.

Makeup Policy: No makeup exams, homework problems, or discussion section (in-class) problems will be given. Absence from the Midterm or the Final will be accepted for the following three reasons only:
Regrades: Any request to have an exam or in-class problem regraded must be made in writing and include an explanation of the believed grading error. In-class problems should be turned in to the TA, and exams should be given to the instructor. On exams turned in for regrades, the entire exam may be considered, and the instructor reserves the right to raise or lower the grade as appropriate. Written requests for regrading of the midterm or in-class problems must be turned in by the end of the class or discussion section in which the midterms or in-class problems are returned.
