There are no computing prerequisites or lab for this course, so the emphasis will be on pencil-and-paper theory. Spring semester is the bad-weather time of year for Fresno, so observing will not be an official part of this class, although observing opportunities may be announced during the semester if they arise.
Too many students treat doing their homework and their assigned readings as dreadful chores. Please remember that astronomy is an elective course and a competitive profession. If working the homework problems and doing the readings isn't fun for you, something is wrong.
Please make every effort to attend every one of these meetings, star parties, and other events. If you don't, Dr. Ringwald will notice. He will also wonder whether you know that most other professions pay more for less effort than astronomy does.
Dr. Ringwald will therefore assign a paper, over 4000 words long, due on the last day of instruction. Since Dr. Ringwald takes this so seriously, he personally reads and grades every one, so make them good!
These papers should be well-thought-out, polished, beautiful gems, not big loads of ore. It will help to focus on a specific topic. A 4000-word paper titled "Stars" can't be very good; stars are complex, and whole books have been written about them. A 4000-word paper on star formation would be a little better, but still, star formation is a vast topic in itself. More like it would be a 4000-word paper on the youngest protostars (also called Class 0).
As another example, a 4000-word paper on "Black Holes" is unlikely to be anything but superficial: whole books have been published on black holes. Pick one black hole, such as the one in V404 Cygni or M87; or pick some aspect of black holes, such as why we think they exist, or how they can evaporate, or how they might be gateways to other Universes.
As yet another example, a 4000-word paper on the Sun would not do our magnificent star justice. A 4000-word paper on the solar neutrino problem may not work, either. What might work would be a 4000-word paper on the recent discovery of neutrino mass with the Super-Kamiokande detector, and its implications for the solar neutrino problem. Other topics that may work may be just one of the many observational results from the SOHO spacecraft, such as the discoveries of how the corona is heated, flare-induced Sun-quakes, or rivers or tornados on the Sun.
For ideas, see the text, including chapters we haven't yet read, as well as current and back issues of reputable popular magazines such as Sky & Telescope, Astronomy, Mercury, Scientific American, and New Scientist. Articles in these magazines are what your papers should be like.
Feel free to use the World Wide Web for research, too, but be careful of what you use, since there's a great deal of rubbish on the web. When using the web for research, be sure as always to reference your sources, by listing their web addresses, also called URLs. Because everything on the web is subject to change without notice, it is also essential to list the date that appears on the page to indicate when it was last updated, as in the above example. If no such date appears on the page, list the version number appearing on the page. If there is no version number, then list the date you consulted the page.
Having something to say in your paper is essential. How you write it is also important: good content is so much better if it's written in a way that's clear and easy to understand. For hints on writing, see The Elements of Style, by W. B. Strunk and E. B. White. This little book is available in the campus bookstore for $6.95. (There will be plenty unsold on the PSci 21 shelf.) There is now an online version, too. Read it from cover to cover twice a year, for life!
These papers may be on any topic in contemporary or historical astronomy, space exploration, or related sciences. A typed (or computer printed) paper title and short summary (between 150 and 250 words) is due on April 23. You're allowed to change your topic after this if you discover something better: this is something I like particularly about science.
Papers must be typed (or computer printed), on standard 8.5-inch x 11-inch paper with standard, one-inch margins, and preferably double-spaced. Use a readable 12-point serif font such as Times or Computer Modern Romannot Chicago, Helvetica, Monaco, or Geneva, which are sans serif and hard to read in large doses.
These papers must provide a list of references, or works cited. Not doing so can turn an "A" paper into a "B" paper. There must be at least five references. No more than two of these five can web addresses. You may use more references than this required minimum: indeed, if you want an A, you should have substantially more.
Here are some useful ways to list references:
For a journal article:
Ringwald, F. A., & Naylor, T. 1998, The Astronomical Journal, volume 115,
pp. 286-295,
"High-Speed Spectroscopy of a Cataclysmic Variable Wind: BZ
Camelopardalis"
For a magazine article:
Ringwald, F. 2000, Astronomy, vol. 28, No. 6, p. 48 (June issue),
"The Sky Down Under"
For a book chapter:
Ringwald, F. A. 1998, in the Third Conference on Faint Blue Stars, edited
by A. G. Davis Philip, J. W. Liebert, R. A. Saffer, and D. S. Hayes
(Schenectady, New York: L. Davis Press), p. 425,
"PG 1002+506: a Be Star at Z = +16 kpc"
For a book:
Warner, B. 1995, Cataclysmic Variable Stars (Cambridge: Cambridge Univ.
Press), p. 221
(Don't forget to include the specific page that contains the information you used. It's too much to expect your reader to wade through the entire book to find what you mean.)
For a web page:
Ringwald, F. A., 1998,
http://zimmer.csufresno.edu/~fringwal/comp2.3lis
"Composite-Spectrum and Related Stars That Are Candidate
Detached Post-Common-Envelope Binaries, v. 2.3" (March 29)
Knowing how the references were used is also important. You should
therefore cite references in the text, especially when making statements
of fact that aren't well-known or immediately obvious. Give the author's
name and the year of publication, so your reader can easily match up the
statements with the references. Here are three different examples of how
to cite references in the text:
Here, Smith (1993) and Horne (1994) were journal articles, but Warner (1995) was a book. Note that with the case of Horne (1994), one can put the author's name into the sentence, useful for emphasizing that Horne did this work.
You need not use this exact format for citing references, but do use a format precise enough so that I can look the references up myself. I get frustrated whenever a student writes something interesting, but gives a reference that's so imprecise, I can't find out more about it!
Here are some other tips on writing:
I will admit that, to enliven my lectures, I sometimes do inject opinions and value judgementssuch as my opinion that total solar eclipses are amazing phenomena that everyone should see, at least once. There is a big difference between spoken and written communication, however. Avoid imitating this when you write: stick to the facts.
"It's" is the contraction of "it is."
"Its" is the possessive of "it," as with "hers" or "his."
This error may be common, but it drives me wild, and can be bad for your grade.
This is how Dr. Ringwald grades papers:
(a) understand or seek clarification about expectations for academic
integrity in this course (including no cheating, plagiarism and
inappropriate collaboration)
(b) neither give nor receive unauthorized aid on examinations or other
course work that is used by the instructor as the basis of grading.
(c) take responsibility to monitor academic dishonesty in any form and to
report it to the instructor or other appropriate official for action.
Instructors may require students to sign a statement on exams and
assignments that “I have done my own work and have neither given nor
received unauthorized assistance on this work." (This section on the honor
code was a required syllabus policy statement by Fresno State.)
DO NOT EVER take papers from the Internet, and turn them in as your work. This is now easy for professors to detect, with www.plagiarism.org. Remember, always: you are responsible for anything that you turn in with your name on it.
Modifying someone else's paper slightly, or changing the words around, or stringing someone else's paragraphs together, even if they're cited, is no better: none of these dubious practices make it your paper. For information on the University's policy regarding cheating and plagiarism, refer to the Schedule of Courses (Legal Notices on Cheating and Plagiarism) or the University Catalog (Policies and Regulations).
To prevent plagiarism, Dr. Ringwald will be copying both the paper titles and summaries and the papers themselves. If Dr. Ringwald finds a plagiarized paper, the student will receive an F for the entire PSci 21 course. Dr. Ringwald may also send the plagiarized paper to the Dean and recommend the student be expelled from the University. Do NOT plagiarize!
Dr. Ringwald will be photographing this class several times, to get to know the class, and during exams, to prevent various forms of cheating.
