Why Take This Class?

If you have ever wondered about the planets, the Sun, the fate of the Universe, black holes, or extraterrestrial life, for example, then you have been doing something that our ancestors have been doing for thousands of years. BUT we live in a special time - one in which we can start to answer many questions.

This course can benefit you in several ways:

If you take this course we will cross the Universe, trying to understand it.


Attendance and Classroom Rules

Attendance is optional. HOWEVER, there are a number of reasons for regularly attending classes. To make class time useful for everyone, please follow the following rules:


Grading Policy

The course grade will be based on the

Exams: Exams are closed-book and will typically be mostly multiple-choice (25-30 questions for each midterm exam, and 50 for the final exam), with one or two essay questions (and usually an additional short answer section on the final). Exams MUST be taken in the class you are registered for if there is more than one section. You will be allowed to bring a single 3-by-5 card to each exam, and you will be able to write whatever you want on that card. My suggestion is that you use it to hold important ideas and definitions that you want to be sure to remember. HOWEVER, the multiple choice questions are NOT geared toward memorization of the material. More often they resemble the thought questions that I will be presenting during most lectures. THE EXAMS WILL ALSO EMPHASIZE MATERIAL FROM THE ONLINE ASSIGNMENTS (see below). The exam questions are intended to test whether you understand the material and can use it, rather than your ability to simply memorize.

The final exam will not be cumulative, but will focus on the material in the last one-third of the class. However, concepts like gravity and light that are covered earlier in the semester will appear since they are important in all areas of astronomy.

POLICY ON MAKE-UP EXAMS: In the case of missed exams, make-ups will only be considered under the direst of circumstances. It is your responsibility to see me as soon as possible to arrange the make-up exam. In cases where a make-up midterm exam is allowed, the exam will be 7 - 10 essay questions (generally about a paragraph long). 3-by-5 cards are NOT ALLOWED on make-up exams.

Reading Quizzes: Reading quizzes will typically be two short answer questions on the reading assigned in the previous class. Reading assignments will be announced in the class before, and will also be posted on the web at the class Blackboard website: blackboard.sdsu.edu. Make-ups will not be given for missed quizzes under any circumstances. However, your lowest five quiz grades will be dropped before calculating your grade. You will be required to use the CPS response pad (the "clicker") on reading quizzes.


Online Assignments

In order for you to get an idea of how astronomers learn, you are going to be asked to complete a number of tutorial assignments outside of class. These assignments will graded online, but MATERIAL FROM THE ASSIGNMENTS WILL BE EMPHASIZED ON THE EXAMS.

TO BE ABLE TO DO THE ASSIGNMENTS, you need to be registered with the Mastering Astronomy website (www.masteringastronomy.com). See the directions on the last page of the syllabus.

The assignments deal with difficult but important concepts in astronomy, and are intended to get you to focus on these topics and seriously think through a series of short questions. It is important for you to figure out for yourself when you do or don't understand something!!!


Observing Sessions

We will have at least one evening observing session during the quarter using telescopes on the roof of the Physics-Astronomy Building. If the weather cooperates, you will have an opportunity to view the Moon, planets, stars, etc. An optional trip to Mount Laguna Observatory will also be scheduled during the semester.   Attending at least one of these sessions during the quarter is strongly encouraged. I will inform you where and when to meet for the sessions.

SDSU also has its own (small) planetarium, which we will use at least once during the semester.


Course Outline

Please keep in mind that the schedule of topics is subject to change. (However, dates of exams will not be changed except under extreme circumstances.) There is a lot of material that can be covered, and it is impossible to do everything. But if you have an interest in something let me know, and I will try to work it in!
