The Economics of Loop Quantum Gravity
Professor Ashtekar's work on Loop Quantum Gravity is featured in the Economist's September 28, 2006 issue: "...Loop quantum gravity... was dreamed up in 1986 by Abhay Ashtekar, of The Pennsylvania State University. He rewrote the equations of general relativity to make them compatible with quantum mechanics. It really took off as an alternative to string theory, though, when it was picked up by Lee Smolin, now of the Perimeter Institute in Waterloo, Ontario, and Carlo Rovelli, of the Universite de la Mediterranee in France. Together, they developed Dr Ashtekar's idea to show that it implies that space and time are not smooth, as general relativity requires, but come in tiny, distinct chunks..."
