Order of Magnitude Astrophysics

This course will introduce you to order-­of-­magnitude estimation, the practice of solving complex problems approximately, within a factor of 10. In this course, you will learn how to estimate solutions by breaking problems into smaller pieces, making intelligent approximations and assumptions, mostly using knowledge you already have. You will also learn how to exercise your order-of-magnitude skills in practical astronomy situations such as in answering questions during verbal exams and talks, designing new projects, and evaluating others proposals.
