In this course, the class will operate as a 'think tank' and consider an important problem for the semester. Like problems presented to a real think tank, the questions for study will be considered to have come from a specific customer who has specific requirements and reasons for requesting the study. The work will consist of three phases: (1) reflection on the question itself and preparation of a workplan to address it; (2) scientific study of the problem; and (3) formulation of recommendations and a final work product for the customer. We elaborate on each of these phases below. Satisfies the Integrative Experience requirement for BA-Astron and BS-Astron majors.
