Welcome to Physics 142! Figure from http://en.wikipedia.org/wiki/Image:Rinjani_1994.jpg. This course is an introduction to electromagnetism, optics and modern physics. It has two components: Lecture and lab. Meets TTh, 11:30 am – 12:45 pm (section 001), or 1:00 am – 2:15 am (section 000), White Hall room 208 Professor: Laura Finzi Email: lfinzi@emory.edu Phone: 404‐727‐4930 Office: Math & Science Center N246 Office hours: Mon 2:30 – 5pm, Wed 10 ‐ 12 am, Th 2:30 ‐ 5 pm, Fri 1 ‐ 4 pm; room TBD, or by appointment. Blackboard: I will regularly use Blackboard for communications and postings. Files will be uploaded in Adobe PDF format; you can download a free PDF reader at: http://www.adobe.com/products/acrobat/readstep2.html Please read all the handouts posted to the conference and do not hesitate to ask, should you have any question. Textbooks: Essentials of College Physics, Serway & Vuille (required), ‐

Physics 142 Laboratory Manual (required), No clickers required Tests are in class on the dates indicated in the course syllabus. An equation sheet will be provided on the tests and final exam. It is the policy of Emory University to accommodate qualified students with disabilities. All students with special requests or needs should let me know their request in person as soon as possible and should accompany it with the confirmation in writing from the Office of Disability and Services (ODS). The Honor Code applies at all times. Homework will be due at the beginning of class almost every class meeting. Homework is submitted through WebAssign. Collaboration with peers is encouraged. However, mindlessly copying someone else's homework won't help you prepare for tests. For more detailed information on homework, please read the document “Homework instructions_12”. Active participation in the class will improve your performance on tests. Physics mentors Program: I encourage you to attend the “Physics mentors” program for PHYS 142 if you find the material challenging. This will be a weekly 1½ hour meeting in a small group with a more experienced undergraduate, to give you extra practice working problems and thinking about physics. Meeting times and locations will be posted on Blackboard. You are strongly encouraged to attend each week throughout the semester for maximum benefit. Tutoring: Free tutoring available through www.epass.emory.edu

May work with others, but in the end you should make sure you can do the work yourself Assignments will be available on WebAssign after each class; answers will be posted on Learnlink You must self‐enroll at www.webassign.net, class key is “emory 0584 4908”. At that webpage, at the top right you’ll see “Account log in” and under that you’ll see “Have a class key?” and that’s the link to select. Tests: 40% ‐

Cumulative Closed‐book closed‐notes, equation sheet provided. Lab: 20% ‐
You must independently pass both the lab and the written portion of the class, to receive a passing grade for the course The scores convert to letter grades as follows: 93.0 ‐ 100 A, 90.0 – 92.9 A‐, 87.0 – 89.9 B+, 83.0 – 86.9 B, 80.0 – 82.9 B‐, with the pattern repeating for C and D grades; 59.9 or less is a failing grade
Doing well in PHYS142 Come to class on time Read the day assignment before coming to class. Work through the examples in the text, write them down. Try to understand as much as possible. Ask questions in class. Work problems. For example, there are 17 conceptual questions and 48 problems at the end of Chapter 15; if you cannot do them all, make a selection. The more you solve, the better. Think through and answer the “Quick Quiz” questions and the “Checkpoints” in the text. The answers are at the back of the textbook. Read “Problem Solving Strategy” when provided in the Textbook. Look at the “Mathematical Review” and other Appendices Work with other students. Note, however, that your homework must be your own which you mastered and understood. Come to office hours if you have questions Take notes in class and mark points that are not clear, so that you can ask about them later.
