Academic Earth - Online Courses

I began sorting my bookmarks today and I've found quite a bit of long lost information.

One of the items I've missed the most (because I forgot the name and therefore couldn't search for it), is Academic Earth.

'Academic Earth is an organization founded with the goal of giving everyone on earth access to a world-class education'

What is it
It is described as 'Free online video courses from leading universities' and on the site you'll find video lectures in a lot of different subjects.
There are lectures in Physics, Psychology, Economics and a lot more.

Or you can choose to follow entire courses within most of the subjects, by following all the lectures within a specific subject (similar to how you would do it at a real university).

Course difficulty range from entry-level through intermediate to advanced.

Oh, and it's free of course.

Who is it
The lectures come from a large variety of universities including Harvard, Berkeley, Yale etc.
The professors (at least the ones I've seen) are really talented and know their subjects very well (why would they teach at a university if they didn't?).
They are all employed at the various universities (you can see each professors affiliation on the site).


How do I follow a course
You can search for courses based on subject, university or instructor (the first course I started following was 'Classical Mechanics' by Walter Lewin at MIT).

And all you need to do is watch the video and learn. If there's something you can't quite hear or make out, you can re-watch it or download a transcript.


So if there's a subject you always wanted to learn about, but you never had the time (or money) to learn it in college, you can do it online at your own pace at Academic Earth.
