Physicist Lee Smolin talks about how the scientific community works: as he puts it, "we fight and argue as hard as we can," but everyone accepts that the next generation of scientists will decide who's right. The problem is that everybody involved is so deeply specialised and siloed they don't see the implications. published in Time and What yawl do is intellectually impressive, but the disease of quantum gravity and cosmology has taken over physics departments all over the world. He is married to Dina Graser, a communications lawyer in Toronto. Phys. Fotini Markopoulou, Lee Smolin, Quantum geometry with intrinsic local causality, Phys.Rev.

Smolin contributed to the theory of loop quantum gravity (LQG) in collaborative work with Ted Jacobson, Carlo Rovelli, Louis Crane, Abhay Ashtekar and others. The theory thus explains why our universe appears "fine-tuned " for the emergence of life as we know it. You might argue that its impractical, but so is much of intellectual endeavour. [], Science is about learning about how the universe works, not seeking aesthetic answers to questions that the universe isnt asking., and yet, theres Democritus, with his picture in all the Chemsitry textbooks. By Marina Corts, Lee Smolin. And what is there to see in quantum gravity except the laborious contortions of an artist throwing himself against the barriers that thwart his desire to express his dream of original research? Admiring unification theory is the same as pouring our sensibility into a funerary urn instead of hurtling it far off, in violent spasms of action and creation. Theor. He has made contributions to quantum gravity theory, in particular the approach known as loop quantum gravity. Unlike Maxwells equations, electroweak theory is abysmally ugly.

The biggest remaining fundamental life science problem, as I see it, is to figure out what chemical reactions are necessary to bootstrap life, and what the statistical probabilities of those occurring are in the early soup. Smolin is one of the bad boys of contemporary physics and cosmology; a generator of radical ideas and an iconoclast.

Certainly, the modern things can be said to be more sophisticated -but it is also more useless for understanding the world. Let us compare E&M to the most successful unification of modern times, the electro-weak theory (a unification of a force governing certain kinds of nuclear decay with that of electromagnetism). Lee Smolin (; born June 6, 1955) is an American theoretical physicist, a faculty member at the Perimeter Institute for Theoretical Physics, an adjunct professor of physics at the University of Waterloo and a member of the graduate faculty of the philosophy department at the University of Toronto..
