Introduces fundamentals of astronomy. Topics include Kepler's and Newton's laws of motion, origin and evolution of the solar system, galactic astronomy, extra-galactic astronomy, cosmology, and modern instrumentation, including space-based astronomy.
This is a really good introduction to astronomy for non majors and is really worth downloading if you are an amateur astronomer. The professor also has a good sense of humour.
