4 courses with the subject ASTR GU, each shown exactly as we captured it from the college's catalog, with every element we hold. Where the wording looks broken, that is our reading of the catalog, not the college's text.
ASTR GU4242ORDER OF MAGNITUDE ASTROPHYSICS3.00
Estimation is an essential skill for astronomy and life in general. This course will introduce to order of magnitude calculations, the practice of solving problems approximately, within a factor of 10. The course will cover examples from planets, stars, compact objects, galaxies and cosmology.

ASTR GU4260MODELING THE UNIVERSE3.00
CC/GS: Partial Fulfillment of Science Requirement Prerequisites: one year of calculus-based general physics. The goal of this course is to provide a basic hands-on introduction to the practice and theory of scientific computing with applications in astronomy and astrophysics. The course will include an introduction to programming, as well as a sampling of methods and tools from the field of scientific computing. The course will include a hands-on project in which students use numerical methods to solve a research problem. Students who are interested in participating in research projects are strongly encouraged to take the course in their sophomore or junior year.

ASTR GU4302General Relativity, Black Holes, and Cosmology3
CC/GS: Partial Fulfillment of Science Requirement Einstein's General Theory of Relativity replaced Newtonian gravity with an elegant theory of curved spacetime. Einstein's theory led to unforseen and unnerving predictions of singularities and cosmological instabilities. Nearly a century later, these mathematical oddities have been confirmed astrophysically in the existence of black holes, an expanding universe, and a big bang. The course will cover Einstein's General Theory, beginning with special relativity, with an emphasis on black holes and the big bang.

ASTR GU4303ASTROSTATISTICS3.00
Astronomers live in era of “big data”. Whilst astronomers of a century ago collected a handful of photographic plates each night, modern astronomers collect thousands of images encoded by millions of pixels in the same time. Both the volume of data and the ever present desire to dig deeper into data sets has led to a growing interest in the use of statistical methods to interpret observations. This class will provide an introduction to the methods commonly used in understanding astronomical data sets, both in terms of theory and application. It is one six classes the department offers every fourth semester
