The history of the universe in 10 minutes
This is an extraordinarily well done video that goes through the history of the universe in 10 minutes.
It splices clips from various videos into one history/chemistry/physics/biology lesson. Even though I was a bio major and am a self proclaimed geek, there were things in this video that surprised me. For example, I had never learned how the moon was created.
If education could be like this, I think the problems in our world will be solved in no time.
