This is an amazing resource of educational, intriguing videos, stories, speakers... and much more! You can search for specific topics, or you can watch more recent postings. I use the videos when I find one that is particularly awesome, or I post links to cool vidoes/stories/articles/talks to my website for students and parents to view if they wish! Most of the videos range in length form a few minutes to about 20 minutes (a few are longer). Contributors to the postings are from all over the world, and many of them participate in TED Conferences around the world!
