Instructor's Course Description:

The first few years of physics study generally concentrate on ideas that were on the cutting edge centuries ago. In this course, we jump ahead and talk about what is being done today on the forefront of physics research - specifically in the study of cosmology. This course is designed for those with a variety of backgrounds and doesn't either assume advanced mathematical knowledge, or require advanced physics courses. We will review the physics that you will need in order to understand the concepts being discussed and keep the discussion largely to the conceptual. Readings will be suggested for those interested in pursuing various topics in more depth.

Cosmology is the study of the history and evolution of the universe. In this course, we discuss the astronomical observables available to us for studying the universe at various stages in its evolution and talk about how physics experiments are designed to reveal the nature of the universe and to use it as a laboratory for understanding fundamental physics. We will discuss what is known about cosmology, how we know it, what remains to be understood, and the ways in which cosmologists are attempting to answer the remaining exciting and difficult questions on the frontier of this rapidly developing field. These questions include the nature of dark matter and dark energy, the state of the universe when it was much less than one second old, and the fundamental origin of our universe.

The course is taught in a lecture format with questions encouraged and expected. There is flexibility in the syllabus for expanding or compressing topics in response to student interest.
