Einstein's Unfinished Revolution

''Quantum mechanics is perhaps the most successful theory ever formulated. The only problem with it, argues Lee Smolin, is that it is wrong ... a fount of provocative ideas ... lucid, upbeat and, finally, optimistic'' Graham Farmelo, Nature

Human beings, says Lee Smolin, author of The Trouble With Physics, have always had a problem with the boundary between reality and fantasy, confusing our representations of the world with the world itself. Nowhere is this more evident than in quantum physics, which forms the basis for our understanding of everything from elementary particles to the behaviour of materials.

While quantum mechanics is currently our best theory of nature at an atomic scale, it has many puzzling qualities - qualities that preclude realism and therefore give an incomplete description of nature. Rather than question this version of quantum mechanics, however, whole groups of physicists have embraced it as correct and rejected realism.
