The Khan Academy




The Khan Academy
<http://www.khanacademy.org/>

The Khan Academy is a not-for-profit organization with the mission ofproviding a high quality education to anyone, anywhere.

We have 1200+ videos on YouTube covering everything from basic arithmeticand algebra to differential equations, physics, chemistry, biology andfinance which have been recorded by Salman Khan. Listen to a recentinterview by Salman with NPR's All Things Considered

Download the Khan Academy factsheet. You can also read more about the KhanAcademy vision in this document.

The Khan Academy and Salman Khan have received a 2009 Tech Award inEducation. The Tech Awards is an international awards program that honorsinnovators from around the world who are applying technology to benefithumanity.

Sal has just launched the alpha version (the software version of a firstdraft) of a new version of the old web app. Try it out if you'reinterested in practicing some of the concepts in the videos.. It requiresa google account (not the login from the old app). The old, slow versionis still available here.

To keep abreast of new videos as we add them, subscribe to the KhanAcademy channel on YouTube.
