Physics PHYS 356 Quantum Mechanics Spring Semester 2015 (4 credit hours) Syllabus Instructor: Office Hours: Schedule: Brandon Hoffman Text: A Modern Approach to Quantum Mechanics by John S. Townsend, University Science Books, 2000. (ISBN13: 978-1-891389-13-9) Description: Modern quantum mechanics with an emphasis on matrix methods. Topics to be covered include time evolution, harmonic oscillators, angular momentum, central potentials, the hydrogen atom and perturbation theory. Prerequisites: PHYS 212, MATH 241, pre/co-requisite MATH 261. Objectives: I have several objectives for this class: Lecture MWF MWF Rm. P-107 2:00 – 3:00PM 8:40AM – 9:45AM Ext. 2350 Rm. P-107 Rm. P-204 1. I would like for you to display a mastery of the course content at an appropriate level for a modern physics course. By this I mean you will have a ready command of the ideas and information covered in class. 2. I would like to see you develop the ability to apply abstract ideas to concrete problems. This will require you to develop your skills of thinking precisely, logically and clearly. It will also require you to perhaps develop a greater degree of mathematical sophistication in your approach to problems. 3. It is my hope that you will develop the ability to think scientifically, that is, that you will develop the habit of mind to always ask yourself “how do I know this is true?” with experiment being the final arbiter in questions of a scientific nature. 4. I would like you to become aware of God’s glory as it is revealed through His creation. Attendance: Excessive absence from class will have a detrimental effect on assigned grades. The instructor will decide on a case-by-case basis whether tests can be made-up. Homework: Problem Sets will be assigned on the dates given in the syllabus and are to be turned in by 5:00pm on the due date. Late homework will not be accepted. Reading: You will be expected to keep up with the assigned textbook reading from the course syllabus. Exams: There will be a midterm and a final examination (both take-home). Makeup examinations will be given only in very unusual circumstances. Test Date Chapters Covered* Monday, Mar. 16 Midterm 1-9 Monday, Apr. 27 Final Comprehensive *Note: only the sections indicated in the syllabus will be tested. Final Exam: The final examination will be comprehensive. No deviations from the college stated time for the final examination will be allowed, except for dire emergencies. Travel arrangements and weddings do not qualify as dire emergencies. Grades: A grading rubric may be found here: http://www.houghton.edu/physics/physics-grading-rubric/ The final grade will represent a weighted average of the scores on the homework, the quizzes, the one-hour tests, and the final exam. The weighting factors will be as shown below: Assignment Percent of grade Homework Midterm Exam Final Exam TOTAL 70% 15% 15% 100% Lecture Schedule 1. Monday, Jan. 12 2. Wednesday, Jan. 14 3.
