With Rovelli he discovered the discreteness of areas and volumes and found their natural expression in terms of a discrete description of quantum geometry in terms of spin networks. LQG is an approach to the unification of quantum mechanics with general relativity which utilizes a reformulation of general relativity in the language of gauge field theories, which allows the use of techniques from particle physics, particularly the expression of fields in terms of the dynamics of loops. Smolin contributed to the theory of loop quantum gravity (LQG) in collaborative work with Ted Jacobson, Carlo Rovelli, Louis Crane, Abhay Ashtekar and others. He was a visiting scholar at the Institute for Advanced Study in 1995 and a visiting professor at Imperial College London (1999-2001) before becoming one of the founding faculty members at the Perimeter Institute in 2001. He held postdoctoral research positions at the Institute for Advanced Study in Princeton, New Jersey, the Kavli Institute for Theoretical Physics in Santa Barbara and the University of Chicago, before becoming a faculty member at Yale, Syracuse and Pennsylvania State Universities. He received his Ph.D in theoretical physics from Harvard University in 1979. Smolin dropped out of Walnut Hills High School in Cincinnati, Ohio, and was educated at Hampshire College. Smolin, became a professor in the Cumberland School of Law in Birmingham, Alabama.
3.3 Experimental tests of quantum gravity.3.2 Background independent approaches to string theory.His research interests also include cosmology, elementary particle theory, the foundations of quantum mechanics, and theoretical biology. He advocates that the two primary approaches to quantum gravity, loop quantum gravity and string theory, can be reconciled as different aspects of the same underlying theory.
He has made contributions to quantum gravity theory, in particular the approach known as loop quantum gravity. Smolin's 2006 book The Trouble with Physics criticized string theory as a viable scientific theory. Lee Smolin ( / ˈ s m oʊ l ɪ n/ 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.
