ScienceHack is a video search site where all the videos are screened by a scientist/specialist to verify their quality and accuracy. It pulls videos from Youtube/Googlevideo/VideoJug etc and presents a neat search page so you can search by discipline. You can also subscribe via rss, so it will automatically update you when new content is added. This is a clip about Milgram’s Obedience to Authority experiments at Yale in 1963.
