Course Content

Astronomy is the study of everything beyond the Earth, the entire universe in fact! Topics will include the sky, planets, stars, galaxies, and more. We won't just take census of the amazing things in the universe; understanding how we know what we know is equally important. Science is the most powerful method of deriving new knowledge ever developed, and understanding science is key to understanding our increasingly complex, technologically driven civilization. Science often relies on math, and astronomy is no exception, although we won't overdo it. We will use simple geometry, trigonometry, and algebra and useful math tools like logarithms and scientific notation. We'll only pull out the math when we need it, and we'll spend whatever time it takes to make its application clear. I sincerely hope you all complete the course with a deeper sense of wonder about the universe and an appreciation for the science that has revealed that wonder.

Lecture

Attendance at lecture is strongly encouraged, but not required. I expect the assigned reading to be completed before class -- this will make lecture easier to follow and better questions. The lectures will not necessarily cover all the topics in the reading and should not be viewed as a substitute for the reading. Lecture slides can be found on the course webpage -- you may wish to print these before class (I suggest importing the slides into powerpoint and printing from there). Lectures are an opportunity to address more challenging concepts and to explore material beyond the text. Please bring questions to class and be prepared to discuss concepts. Please also bring a scientific calculator to class (which should have at least a "log" button and support scientific notation, but does not have to be expensive or fancy). We will sometimes work problems in class to make sure everyone is getting it.

Laboratory

Attendance at lab is required. Jim Verley, Mark Reiser, and Travis Laurence are your dedicated lab instructors and will have their own lab syllabus. Lab meets for the first time the week of Jan. 26--30 (next week). A few labs (one required, probably plus an additional optional one) will involve nighttime observing with a telescope and you will be able to sign up for a night of the week that will work for you for these.

Homework

In addition to the reading, weekly homework assignments will be posted on-line via the University's WebCT system and due as indicated (typically a week later). The procedures for self-registration are explained at http://www.uwyo.edu/ctl/webct (this is also the login site). Additional course information will be available on WebCT. Please see me if you have difficulties with WebCT -- they are usually easy to solve. Not doing the homework WILL hurt your grade!

Exams

There will be three in-class exams during the semester, plus a final exam (which will be over the solar system, not the entire course). While the exams will not be comprehensive in general, the material in the course does build on itself and several topics reappear in different forms. Each in-class exam will cover several chapters of material and consist of multiple choice problems. Bring a GREEN 10 ANSWER SCAN FORM and your CALCULATOR! The exams will be closed-book, but formulas and physical constants will be provided and need not be memorized. Exam dates are Feb 4, Mar 11, Apr 13, and May 2 (Monday of finals week).

Extra Credit

There will be chances for extra credit this semester. On Fridays we will discuss news articles about astronomy -- you can earn extra credit (equivalent to about one homework) for bringing in an article once. There may be other opportunities announced during the semester.

Grading

The grading scheme will be:

A = 85-100%

B = 75-85%

C = 65-75%

D = 55-65%

F < 55%

I tend to round up, and I reserve the right to adjust the scheme in your favor if the score distributions are lower than expected (for instance, I will curve exams). You will not automatically fail the course for missing lab, but if two or more labs are missed you will lose a letter grade. The components of the course are weighted:

Laboratory = 25%

Exams = 60%

Quizzes/Homework = 15%

Special Accommodations

Please let me know if you have a disability that requires special accommodations. Procedures exist to address such needs through Disability Support Services (766-6189; udss@uwyo.edu).

About Me

I am an observational astronomer specializing in the study of quasars and other types of active galaxies thought to be powered by super-massive black holes. I received my PhD from the University of Texas at Austin and have previously worked at Lawrence Livermore National Laboratory and Kitt Peak National Observatory. I've really used the Very Large Array (the "VLA", a radio telescope in New Mexico featured in the movie Contact), the Hubble Space Telescope, and the Chandra X-ray Observatory, so I can provide you with first-hand details not found in textbooks. I'm also a science fiction writer my first novel Star Dragon is about an expedition to a distant binary star system. The paperback is available now, and the full text can also be downloaded for free from http://www.mikebrotherton.com.

I love astronomy and look forward to sharing the wonders of the universe with you!

I encourage you to read Chapter 20, "Life on Other Worlds," but we may not get to it before the end of the semester.

 

I will be absent for research-related reasons a few times this semester. The only date I am certain of is Jan. 12 (I will be attending the American Astronomical Society meeting in San Diego). I may have to miss more classes to observe in Arizona and Hawaii and will let you know in advance when I know the specific dates. There will be a substitute lecturer on these days (probably Jim Verley).
