It took another decade for him to earn his doctorate in physics from the University of Tennessee. After receiving bachelor's and master's degrees in electrical engineering at the University of Kentucky, he joined ORNL's Health Physics Division in 1949 as the Lab was building a body of groundbreaking work in the study of radiation health effects. World events, nevertheless, provided opportunities: While serving in the Army Air Corps during World War II he attended scientific programs at Kenyon College, Yale Communications Cadet School and the Michigan Institute of Technology. Rufus Ritchie came from Kentucky coal country, a region not known for producing physicists.
Could this miracle be true? Crazy as it sounded, they soon discovered an even more bizarre possibility. Randall said, “and gravity will be incredibly weak.” A result was a natural explanation for why atomic forces outgun gravity by 10 million billion to 1.
“You can be only a modest distance away from the gravity brane,” Dr. So we experience gravity as extremely weak. Suppose, they said, that gravity is actually inherently as strong as the other forces, but because of the warping gravity is much much stronger on one of the branes than on the other one, where we happen to live. Such a situation, they realized to their surprise, could provide a natural explanation for the hierarchy problem without invoking supersymmetry.
Objects, for example, would appear to grow larger or smaller and get less massive or more massive as they moved back and forth between the branes. When they solved the equations for this setup, they discovered that the space between the branes would be warped. Sundrum’s model consisted of a pair of universes, four-dimensional branes, thinly separated by a five-dimensional space poetically called the bulk. “What they drew pictures of was a kind of Oreo cookie multiverse, an architecture similar to one first discovered as a solution of the string equations by Edward Witten of the Institute for Advanced Study and Petr Horava, now at Berkeley. This passage describing Lisa Randall’s first insight into a problem from a recent New York Times profile of her brought back fond memories of my conversations at the Society of Fellows (or more accurately, listening to other people having conversations, because I was so confused that I couldn’t even be part of it): One of the people I got to talk to there was the physicist Lisa Randall, who recently wrote a pop physics book entitled “Warped Passages” that seems to be selling well. It is an interdisciplinary academic club which draws top young scholars from across a wide array of disciplines whose only obligation is to do great research and drink expensive wine. in economics, I had the incredible luck to get to spend three years at something called the Harvard Society of Fellows.
