ASTR 4800 - Space Science: Practice and Policy
Exposes students to current controversies in science that illustrate the scientific method and the interplay of observation, theory, and science policy. Students research and debate both sides of the issues, which include strategies and spin-offs of space exploration, funding of science, big vs. small science, and scientific heresy and fraud. Recommended prerequisite: one year of college level astronomy or physics.
