Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan to provide "a free, world-class education for anyone, anywhere".
Founded by Stephen Wolfram in 1987, Wolfram Research is one of the world's most respected computer, web, and cloud software companies—as well as a powerhouse of scientific and technical innovation. As pioneers in computation and computational knowledge, we have pursued a long-term vision to develop the science, technology, and tools to make computation an ever-more-potent force in today's and tomorrow's world.
Over the course of more than a quarter of a century, we have progressively built an unprecedented base of technology that now makes possible our broad portfolio of innovative products. At the center is the revolutionary Wolfram Language, which defines a unique convergence of computation and knowledge.
