Conrad Wolfram: a new perspective on teaching math to the kids

Conrad Wolfram is the strategic director of Wolfram Research, where his job, in a nutshell, is understanding and finding new uses for the Mathematica technology.
Here, within the TED series of speeches, he talks about a new perspective in teaching kids real math with computers.
Why? Well, simply because
"calculation by hand -- isn't just tedious, it's mostly irrelevant to real mathematics and the real world."
Enjoy!
