Obviously I am a fan of math and science videos. I mean, who isn't? But sometimes when I am watching a posting on YouTube or Metacafe, I wonder about the reliability of the video. Well there is a new video search engine out called ScienceHack. It alleges that every video is screened for accuracy by a scientist before it is posted. Of course, there's no mention of who that scientist is, or what his or her credentials may be. Still, I perused it a little and was quite impressed. The site is obviously in its infancy, but I think we can expect big things as it grows.
