Lecture: 1:30 – 2:20, MWF
Text: Universe: Stars and Galaxies, 3rd Edition – Roger A. Freedman and William J. Kaufmann, III

Over the course of this semester we will delve into the science of astronomy. The course will cover a wide range of material in an introductory way. The overall goal is for you to leave the course with an appreciation of astronomers as scientists: how they think, what they know, and how they know it.

Astronomy relies heavily on physics and mathematics, and we will use both in developing our ideas. You will need a pocket calculator capable of doing trig functions and logarithms. This semester we will concentrate on 1) the basic physics which we need to understand astronomy, 2) stellar astronomy, and 3) cosmology, and will leave the study of the constellations, planets, and other topics to your own interests. We will do telescope observing only as time and weather allow.

The daily assignments below show where we will most likely be - you should read the assignment before coming to class. The ideas we will discuss in class will focus on the more difficult aspects of astronomy and will provide the structure for better understanding of the other topics. These lectures build on your reading of the text and on each other from day to day and you must keep up in order to see the beauty and coherence of our subject. The best way to get help is to ask for it; questions are always welcome. We will have brief quizzes at the beginning of some classes to make sure you are doing the reading and keeping up. I will also be available after every class to answer questions that may have occurred to you. Office hours will be determined by your schedules. This course is a joint effort among all of us. I will expect you to work hard to get the most out of the course, just as I expect myself to work hard to enable this happen.

You will have a number of homework assignments, as described on the separate sheet that will be distributed. The three reviews will cover the material from the text, from the lectures and from the homework. All of these activities are governed by the Honor Code.

Because the material builds from day to day, class attendance is essential. The cut limit for the course is 8 (20% of the classes). Any cuts beyond that will result in an F for the course. Sign in for yourself on the sheet every day that you are present. The Honor Code governs this as well.
