Heisenberg's Uncertainty Principle

Misha Glenny and guests discuss one of the wonders of the natural world. In 1875 in the western Pacific, the crew of HMS Challenger discovered the Mariana Trench which turned out to be deeper than Everest is high, by two kilometres. Trenches like Mariana form when one tectonic pl ...  Show more

In the 1860s, James Clerk Maxwell argued that light was a wave of electric and magnetic fields. But it took over four decades for physicists to put together the theory of special relativity, which correctly describes the symmetries underlying Maxwell's theory. The delay came in p ...  Show more

On May 6th, 1981, at the MIT Endicott House, a group of computer scientists gathered together with elite physicists to make the case that quantum phenomena could be used for computation. Here, ideas that would influence the next four decades of quantum computing research and deve ...  Show more
