COURSE OVERVIEW

This course will lead you on the longest, farthest journey possible: through the known Universe, and back in time 15 billion years to the Big Bang. Two major goals will be addressed throughout the semester: Along the way, you'll learn about the Four Forces of Physics that describe virtually everything in the physical Universe, and you'll also come to appreciate the almost overwhelming beauty of the natural world.

The course is organized into four sections:

  1. Naked-Eye Astronomy: You probably know more than you think
  2. Tools of Astronomy: The Physics of Light; Spectra
  3. Stars: Their birth, life, and death
  4. Galaxies and Cosmology: The Origin and Fate of the Universe

Format

Course material will be explored in the two lectures every week; readings from the text; and homework (see Requirements for more details). However, there will be ample opportunity for individual exploration and interaction -- just as there is in scientific research. You are encouraged to ask questions in class and during office hours; to visit the telescope on Orchard Hill and the planetarium at Amherst College; and in general to let only your imagination be the limit.

Not everything from the reading will be covered in class lectures but you are responsible for all the material covered in the readings. I will try to cover the more difficult to understand topics during class lectures. Science is more than just memorizing facts. I will try to teach you to think analytically and logically, like a scientist. Hence the answers to some exam questions will not be found as a single fact in either the reading or the lecture notes but will require you to put one or more facts together.

The Home Page for this class is at URL http://www.astro.umass.edu/~nsk/a100.

Class notes will be posted on the WWW before each day's class. You are encouraged to read them before class. These are meant to aid your studies and not to replace the reading or lectures.

Why Should I Care?

This course will cover larger topics -- measured by mass, size, age -- you name it! -- than any other class you will ever take. This is good. The concepts are actually not hard to grasp. More importantly, you are now living in a complex, modern society where science plays an ever-increasing role. It is crucial that you understand how science and scientists actually work, since you will find yourself voting on, reading newspaper articles about, and probably using the products of scientific research every day for the rest of your life. Perhaps this course will spark a life-long interest in science; perhaps not. In any event, the thought processes and reasoning skills you develop this semester should stand you in good stead in situations far surpassing this single undergraduate 3-credit course.
