FS/Ay 3.
Freshman Seminar: Automating Discovering the Universe.
6 units (2-0-4):

Powerful new instruments enable astronomers to collect huge volumes of data on billions of objects.

The tool chest of future astronomers will involve facility with "big data", developing clever queries, algorithms (some based on machine learning) and statistics, and combining multiple databases. This course will introduce students to some of these tools. After "recovering" known objects, students will be unleashed to make their own astronomical discoveries in new data sets.
