Lee Smolin
"What is space and what is time? This is what the problem of quantum gravity is about. In general relativity, Einstein gave us not only a theory of gravity but a theory of what space and time are--a theory that overthrew the previous Newtonian conception of space and time. The problem of quantum gravity is how to combine the understanding of space and time we have from relativity theory with the quantum theory, which also tells us something essential and deep about nature." LEE SMOLIN is a founding and senior faculty member at Perimeter Institute for Theoretical Physics in Waterloo, Canada. He is also Adjunct Professor of Physics at the University of Waterloo and has just been appointed to an adjunct position in the Department of Philosophy of the University of Toronto. He is the author of more than 140 scientific papers and has made major contributions to the quantum theory of gravity, being a co-inventor of loop quantum gravity and deformed special relativity. Smolin is an engaging and experienced public lecturer, who has given talks to a wide variety of audiences in North America and Europe. His popular essays have appeared in The New York Review of Books, The New York Times Book Review, Time Magazine, Scientific American, Forbes, Update, The Times Higher Education Supplement, Prospect Magazine, New Scientist, American Scientist, Discover, Physics Today and Physics World, among others.
