| Lee Smolin is a theoretical physicist whose work is concerned with the problem of completing the revolution in physics started early in the 20th Century by the discoveries of special and general relativity and quantum mechanics. His main contributions have concerned the problem of quantum gravity, which is the problem of unifying quantum theory with gravity and spacetime. He has worked on several different approaches including loop quantum gravity, string theory, dynamical triangulations and causal set theory, although he is perhaps best known for his work on loop quantum gravity. He has also worked on problems in cosmology, elementary particle physics, the foundations of wquantum theory and theoretical biology, and he has a strong interest also in philosophy. | |
