One year each of high school chemistry and physics are strongly recommended but not required. Because this class takes a quantitative approach, participants should be comfortable using their math skills to solve problems. Calculus is useful but not necessary.
“I loved learning about our universe, and the activity about going to Mars was super fun! I think I also learned a lot about group work and collaborating efficiently.” – Jacqueline C. | Oakland Gardens, New York
This course traces our knowledge of the universe from astronomy’s ancient roots to the modern study of extrasolar planetary systems, cosmology, and black holes. We begin with Newton’s laws of motion and universal gravitation, Kepler’s laws, orbital dynamics, and space travel. Next we take up the nature of light, the structure of matter, the emission and absorption of light by matter, and nuclear physics. We apply this knowledge to describe the properties of our sun and of the planets of our solar system, the properties and fate of stars in general, and the discovery of planets around other stars. Further topics include galaxies and the dark matter and black holes they contain, supernovae and the creation of chemical elements, and the expansion of the universe. We end with Einsteinian cosmology, the cosmic microwave background, dark energy, and the fate of the universe.
