Around us we see a vast, expanding universe of galaxies. The galaxies are composed of stars around some of which orbit planets. At least one of these planets in the universe is inhabited by an astoundingly complex set of living things. Where did all this come from? This course presents an overview of the formation and evolution of the universe, the solar system, planet Earth, and life on our planet. Lectures and readings will be supplemented by astronomical observations, computer simulations, and laboratory experiments (at times to be arranged.) No prerequisite.
