Fall 2000 class taught by Michel Janssen, University of Minnesota.
Note: syllabi dates have been removed, be sure to insert your relevant dates in where necessary.
This course is an introduction to the work of historians and philosophers of science trying to trace the conceptual development of 20th century physics. Our main focus will be on the development of relativity theory (both special and general) and quantum theory in the first quarter of the century. Special attention will be paid to the contributions of Albert Einstein. Readings are taken from a variety of sources. General surveys are used to get us started on a particular topic (for a list of these topics, see the "Schedule" on pp. 3-10 below). That will prepare us for more specialized literature in history and philosophy of science. We will also read (passages from) some of the seminal texts written by the physicists we will study, both to get some of the flavor of their work and to evaluate interpretations and reconstructions of these texts offered in the historical and philosophical literature.
The course will basically be run as a lecture course, but with ample opportunity for discussion. Class presentations are not required, but volunteers are welcome. Sessions 4, 8, and 9 (see "Schedule" below) are especially suitable for student presentations, as well as—depending on your background—sessions 10, 14, and 15.
The basic requirement for this class is to keep up with the reading assignments (see "Schedule" below). Do the reading for any given week before you come to class, so that you are well prepared to follow the lecture and to participate in discussion. There will be three take-home exams that will test your understanding of the readings and the discussion of them in class. These exams will consist of 2-4 essay questions each requiring an answer of 1-3 typed, double-spaced pages. The 1st take-home will be on the material covered in weeks 1-5, and will handed out at the end of class; due one week later. The 2nd take-home will be on the material covered in weeks 6-10, and will be handed out at the end of class; due one week later. The 3rd take-home will be on the material covered in weeks 11-15, and will be handed out at the end of the last day of class; due one week later at 5 PM. If you volunteer to do a class presentation, you have the option of substituting your presentation for parts of one of these take home exams.
Additional requirement for graduate students: in addition to the above, graduate students are required to write a 10-20 page (double-spaced) paper on any topic in the history of 20th century physics (it can but does not have to be in an area covered in class). A short proposal for your paper (including a list of sources to be consulted) is due at the beginning of class November 21. You are encouraged to discuss a possible topic with me earlier in the semester. I will pass out a style sheet with suggestions for footnote and citation formats. The paper is due when the final exams are due, at 5pm.
Undergraduate Students: 3
take-home exams (30% each); class participation (10%).
Graduate Students: paper (30%); 3 take-home exams (20% each); class participation (10%).
All grades will initially be given on a scale from 0 to 100 and will only in the end be converted to letter grades. The conversion will roughly be as follows: 80-100: A; 70-80: B; 60-70: C; 50-60: D; less than 50: F.

Items 1 & 3-6 should be available at the bookstore. Item 2 is out of print. You will be able to borrow a copy from Prof. Stuewer's personal library. Do not write in these copies! A photocopy of readings from other sources (see "Schedule" below) will be available in the office of Barbara Eastwold (Tate Laboratory of Physics, Rm. 381) one week before the session in which the material is covered (with the obvious exception of the first class).
Since the discussion of the assigned readings in class is an integral part of the course, attendance is mandatory. Attendance sheets will be passed out at the beginning of each class. Unexcused absences will be reflected in your grade for class participation. More importantly, missing class will put you at a disadvantage when writing your short essays for the take-home exams.
If you have difficulty with the material, do not wait too long and come see me during office hours. I will do my best to answer any questions you may have, from very specific ones to "I'm lost!"
Present your own ideas and your own arguments and present them in your own words. Use quotations sparingly and give detailed citations whenever you do. Note that simply changing a few words in a quotation does not change the fact that you are quoting. Paraphrasing of this sort, where you use a source almost verbatim without acknowledgment, is the most common form of plagiarism among undergraduates. Another common problem may arise from collaborating with other students. You are free to discuss the take-home exams with other students but the work that you submit must be your own, not something jointly written or copied from another student. You will not receive any credit for work that violates these rules against plagiarism.
For each week, a number of readings are listed. The readings are divided into three categories labeled A, B, and C. The ones under A should be read by all students. Graduate students are also expected to read those under B. These are optional for undergraduate students. However, since I will typically draw on the readings under both A and B in class, undergraduate students are strongly encouraged to read as much as they can from the readings under B. Readings under C are suggestions for further reading.
