Course Description
This course surveys current understanding of the physical cosmos. First we develop our backyard perspective, repeating the observations of the ancients and noticing the same patterns of motion. We interpret motions in both ancient and modern perspectives. Next we develop an understanding of moving bodies, culminating in orbital motion due to gravity. We then consider the "geology" of planets in our solar system.
In Part 2, we examine stars including our Sun, understand how they work, how they are born, evolve, and die. We consider how planets form, and the possibilities of life around other stars.
The final part of the course examines how stars and other matter are organized into our galaxy, how galaxies are distributed in space, and how they evolve. We discuss the evolution of the universe, looking back to the time of its formation and speculate on it, and our, future.
The final exam will cover part 3, and will also include questions on parts 1 & 2. All 4 tests are short answer (1 or 2 sentences at most)
