The idea of this junk drawer is simple. Share links to sites/webpages that drop knowlegdge like it's hot.
The first thing I have for you is a video called imagining the 10th dimension. The explanation is very good (IMO) but the concepts are hard to wrap the mind around. If it takes you 5 play throughs to understand it you're probably ahead of the curve.
The next thing I have for you is pretty much the best site I've seen since Blazers Edge. From their about section, "We believe passionately in the power of ideas to change attitudes, lives and ultimately, the world. So we're building here a clearinghouse that offers free knowledge and inspiration from the world's most inspired thinkers, and also a community of curious souls to engage with ideas and each other." Basically, the site consists of videos of talks given on a variety of subjects, from science and technology to business, politics, music, culture and everything in between. Everyone should be able to find a video that piques their curiosity.
Update: I'm adding a few more links that I like and didn't put in the midnight edition. Also, I recommend Norsk's BIG post for lots of great links.
