Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity --dark energy -- is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking -- one that may change forever our notions of where the Universe came from and where it is going.$64.95

Based on 20 years of research and interviews with intimate friends and associates willing to discuss Einstein as never before, this riveting book details his childhood and youth. Contains extensive material on his adult life never published before to reveal the crux of Einstein's personality and private life in a way few others have. Includes rare photographs.$29.95
"Develops one fresh new insight after another...In the great tradition of physicists writing for the masses, The Elegant Universe sets a standard that will be hard to beat." -- The New York Times Book Review
In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.
Green uses everything from an amusement park ride to ants on a garden hose to illustrate the beautiful yet bizarre realities that modern physics is unveiling. Dazzling in its brilliance, unprecedented in its ability to both illuminate and entertain, The Elegant Universe is a tour de force of science writing-a delightful, lucid voyage through modern physics that brings us closer than ever to understanding how the universe works.
