If you're interested in airplanes and wish you knew more about aerodynamics -- or air traffic control, space policy, satellite engineering or airline management -- you can study all of those topics and more, for free, at the Massachusetts Institute of Technology, via their OpenCourseware website. Each course features a syllabus, readings, video lectures, and projects that you can complete at your own pace. The courses don't include any instructor support, classroom interaction or certification, so learners must be self-motivated. If you prefer more structure, MIT also offers MOOCs, or massive online open courses, together with Harvard, at the EdX website. These courses run on a schedule and offer active discussion forums, and students can receive a certificate when they complete all the coursework.
