Stephen Wolfram: Computing a theory of everything | Video on TED.com
This is a must watch video for everyone. Stephen Wolfram has been one of the most influential computational experts who started out as a physicist in the world. His software, "Mathematica" is arguably the best symbolic computation software out there. It is a very very useful to mathematicians, theoretical physicists, and probably other scientists and engineers. To me, it has really helped in in dealing with long derivations in my field. Enjoy!
Stephen Wolfram (born 29 August 1959) is a British physicist, software developer, mathematician, author and businessman, known for his work in theoretical particle physics, cosmology, cellular automata, computational complexity theory, computer algebra and the Wolfram Alpha computational knowledge engine.
