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.$54.95
The common language of genius: Eureka! While the roads that lead to breakthrough scientific discovery can be as varied and complex as the human mind, the moment of insight for all scientists is remarkably similar. The word "eureka!", attributed to the ancient Greek mathematician Archimedes, has come to express that universal moment of joy, wonder-and even shock-at discovering something entirely new. In this collection of twelve scientific stories, Leslie Alan Horvitz describes the drama of sudden insight as experienced by a dozen distinct personalities, detailing discoveries both well known and obscure. From Darwin, Einstein, and the team of Watson and Crick to such lesser known luminaries as fractal creator Mandelbrot and periodic table mastermind Dmitri Medellev, Eureka! perfectly illustrates Louis Pasteur's quip that chance favors the prepared mind. The book also describes how amateur scientist Joseph Priestley stumbled onto the existence of oxygen in the eighteenth century and how television pioneer Philo Farnsworth developed his idea for a TV screen while plowing his family's Idaho farm.
