I’m way behind on this–but since it was new to me I figured it might still be new to a few folks I know. Did you know that several “elite” universities including Yale and Harvard now offer audio and video from courses for free online through iTunes U? I’ve been listening to a philosophy course on death at Yale via my phone in the car and on the train for the last month or so and having my mind blown with a whole new line of thought I’ve never been exposed to (I’ve never taken a philosophy class before).
Mashable has a great article on Free College: How to Audit Courses From 7 Elite Schools Online if you want to learn about more options. Keep being curious and learn new things. Enjoy!
