The goal of this course is for students to enhance their view of the physical world by allowing them to acquire a basic understanding of modern astronomy using recently available astronomical data. Major topics include constellations, the Sun, stellar types, motions, parallax, magnitudes, luminosity, spectra, classifications, clusters, evolution, quasaurs, nebula, galaxy classification and composition, the Big Band, and cosmology.
This course will focus on conceptual understanding rather than mathematical manipulation. However, as mathematics is the language of science, it is expected that you can perform basic algebraic calculations and recognize basic geometric relations throughout the course.
