Teaching the world through internet

This initiative is truly one very good example of how internet can be used to benefit other people: Salman Khan has set up the Khan Academy, a not-for-profit organization with the mission of providing a high quality education to anyone, anywhere. On his website www.khanacademy.org he provides over 1400 YouTube videos covering everything from basic arithmetic and algebra to differential equations, physics, chemistry, biology and finance. It provides great material for high school students, but also for adults needing a mathematics or physics reminder it is highly valuable. A very admirable initiative!
