LEE SMOLIN Founding and Senior Faculty member at Perimeter Institute for Theoretical Physics in Waterloo, Canada; Adjunct Professor of Physics at the University of Waterloo; Author, The Trouble With Physics Perhaps the most embarrassing example from 20th Century physics of a false but widely held belief was the claim that von Neumann had proved in his 1930 text book on the mathematical foundations of quantum mechanics that hidden variables theories are impossible. These would be theories that give a complete description of individual systems rather than the statistical view of ensembles described by quantum mechanics. THALER'S QUESTION - An EDGE Special Event

Weasel program Hamlet: Do you see yonder cloud that's almost in shape of a camel?Polonius: By the mass, and 'tis like a camel, indeed.Hamlet: Methinks it is like a weasel. The thought experiment was formulated by Richard Dawkins, and the first simulation written by him; various other implementations of the program have been written by others.

The PHYLO project.
Well now, this is an interesting discovery: astronomers have found what looks like a "super-Earth" – a planet more massive than Earth but still smaller than a gas giant – orbiting a nearby star at the right distance to have liquid water on it! Given that, it might – might – be Earthlike. This is pretty cool news. We’ve found planets like this before, but not very many! And it gets niftier: the planet has at least five siblings, all of which orbit its star closer than it does. Now let me be clear: this is a planet candidate; it has not yet been confirmed.

Your hands are, roughly speaking, 360 million years old. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. The Loom
