24.112: Space, Time, and Relativity, Fall 2011

Instructor: Brad Skow.
Office Hours:No regular office hours; but I am in all day on most days. Email to make an appointment. Short notice (same day appointments) usually work out.
Grader: Jay Hodges. Email: jh4@mit.edu; office: 32-D912.
Lectures: MWF, 10am, 2-147.
Requirements:There will be four (4) homework assignments, two (2) short papers of five to seven pages, and several take-home quizzes. The topics of the homework assignments are: (1) Newton's arguments; (2) the status of velocity; (3) the geometries of spacetime; (4) time travel. Homework (3) will not contain much philosophy; it exists to help you learn the (small amount) of math and physics presented in class. For the short papers you will have several topics to choose from. The homework assignments are worth 25% of your grade; the quizzes, 10%; and the papers, 65%.
On Quizzes:Occasionally I will announce that there will be a "take home" quiz due at the next class meeting. The quiz will be some short question about the reading. I will give you the question in class and also put it on this web page. I may (anonymously) read out some of the handed-in answers as part of the class discussion.
Grading Policies:You may work on homeworks with other students, but your write-up must be your own. Papers and homeworks (1), (2), and (3) will receive one of four grades: A, B, C, or F. The first paper and each of the first two homeworks may be re-submitted for a second grade (provided the original grade was not an F). If you re-submit an assignment your final grade on that assignment is equal to the higher of the two grades. (If the assignment is a homework, you do not need to re-write all your answers; just the ones you want to change. You have 1 week to resubmit an assignment. Resubmit it with the original, graded assignment.) Similarly, your first paper may be re-submitted for a second grade. Quizzes are graded pass/fail.
Note on Readings:Each reading should be done before the class for which it is assigned. The number of pages assigned in this class is small, but the readings are difficult. You will not fully understand them if you read them just once.
Homework:HW1 (due 9/23) | HW2 (due 9/30) | HW3 pt1 (due 10/17) | HW3 pt 2 (due 10/24) | HW4 (due 11/30) | comments on HW4.
Quizzes:QZ1 | QZ1 solutions, comments | QZ2 | QZ2 comments
Papers:Paper 1 (due 10/14) | Paper 2 (due 12/14)
Resources:Guidelines for writing philosophy papers.
