YouTube has just released a new sub-site called YouTube EDU, aggregating thousands of free lectures from over a hundred US universities including MIT, Yale, Harvard, Stanford, and oh-so-many more. Earlier this week we highlighted another similar application called Academic Earth, and just two days later, here comes YouTube EDU. It's incredible to see such great options for folks looking for some free education. The two services are very similar in some ways, and while YouTube's landing page isn't quite as useful as Academic Earth's, they're both packed full of great content. Head to the Directory page to browse through all the university options, and when you pick one, you can see all of the full courses or individual lectures available. According to weblog Open Culture, YouTube EDU currently has over 200 full courses, so you're bound to find something that piques your interest—like MIT's Introductory Quantum Mechanics II. It's really exciting to see the web embrace and distribute all this free learning, and we're eager to see both services grow.
