Welcome to Physics 152! Figure from http://en.wikipedia.org/wiki/Image:Rinjani_1994.jpg. Instructor: Jed Brody Email: [email protected] Phone: 404-727-5580 Office: Math & Science Center N308 (please also check N307 and N309!) Textbook: Serway and Jewett, Physics for Scientists and Engineers (Chapters 23-38) This course is an introduction to electromagnetism. The importance of electromagnetism cannot be overstated. Electromagnetic theory allows us to answer the following questions about common observations: Why do balloons stick to the wall after you rub them over your hair? What causes the heart to beat? Why do magnets stick to the refrigerator? How do cameras, microscopes, and telescopes work? Why is the sky blue? I welcome and encourage questions at all times: in class, in my office, through email, and over the phone. Office hours are tentatively scheduled for Tuesday 11-12 and Thursday 2-3. You are always very welcome to make appointments or drop by at other times. Labs begin on Monday, January 26. Grades will be computed as follows: Three tests: 45% (9% for your lowest test grade, 18% for each of the other two) Final exam: 25% Lab: 20% (and you must pass lab to pass the course) Homework: 10% Letter grades will be determined as follows: A = 93.0-100, A- = 90.0-92.9, B+ = 87.0-89.9, B = 83.0-86.9, B- = 80.0-82.9, etc. The Honor Code applies at all times. No equation sheets will be provided on the tests or final exam. You may bring one handwritten, double-sided, 4 x 6 index card to the first test, two such cards to the second test, three to the third, and four to the final exam. Homework will be due at the beginning of class every Wednesday and Friday (exceptions: the first week of class and the weeks of tests). Homework is assigned and submitted through www.webassign.com. Please visit the website and add yourself to the class with this Class Key: emory 0295 0853. (If you're reading this before January 13, you may need to wait until January 13 to access the course on webassign.) Collaboration with peers is encouraged. However, mindlessly copying someone else's homework won't help you prepare for tests. Upon request, you will be granted one-week extensions on two homework assignments. Email extension requests to me. Please try to save your extensions for when you really need them. Physics is challenging but fun! Remember, I'm here to help you learn as effortlessly as possible, so please never hesitate to contact me!
