Introductory Astronomy Online Course
My own personal MOOC.
This is a series of introductory lectures on astronomy and astrophysics. My goal is to eventually have a complete online course covering nearly all areas of introductory astronomy in lecture form. In doing this series, I will be violating a number of "good video" practices, including video runtime length, number of technical events, and the use of flashy graphics and music. The reason is that I am trying to demonstrate what it means to internalize and talk about a subject off-the-cuff for 15 minutes or more. It is not often that people do this, and frequently, you only get this in a full college course, which this series seeks to emulate. This can also be used to supplement your own coursework in your astronomy class.
