Educational Sites Worth a Peek

WatchKnow

Dr. Larry Sanger, co-founder of Wikipedia, has created a website that sifts through the fluff and delivers only educational videos. Dr. Sanger says, ” think of it as YouTube meets Wikipedia, filtering out everything but quality educational videos.”
All the videos on WatchKnow are hosted by external websites (National Geographic, YouTube, etc.) which may cause issues with filtering software, but so far, I’ve found it easy to use and loaded with lots of great content.

WolframAlpha

WolframAlpha is a “computational knowledge engine.” A normal search engine returns links based on search parameters. WolframAlpha returns answers.
For example, I typed in “December 25″ and Wolfram returned:

  • Christmas Day
  • Birth of Hal Scardino (actor)
  • Gorbachev resigns as president of Soviet Union
  • Cyclone hits Australia (1974)
  • Coronation Stone is stolen (1950)
  • Daylight information
  • …etc.
