In this book Stephen Hawking takes us to the cutting edge of theoretical physics to explain in laymen's terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science-the elusive Theory of Everything that lies at the heart of the cosmos. He guides us on his search to uncover the secrets of the universe-from supergravity to supersymmetry, from quantum...

Do we really know what time it is? Cern physicist Professor Brian Cox (and author of E=mc2) unlocks the secrets of time in this entertaining and informative program. His journey starts with the Sun, our historical dictator of time, but Brian discovers that the world doesn't always spin like clockwork in fact, it flutters, like an irregular heartbeat. In his search for a more reliable way to tell the time, he experiences the physical definition of...

Albert Einstein and Erwin Schrodinger were friends and comrades-in-arms against what they considered the most preposterous aspects of quantum physics: its indeterminacy. Einstein famously quipped that God does not play dice with the universe, and Schrodinger is equally well known for his thought experiment about the cat in the box who ends up 'spread out' in a probabilistic state, neither wholly alive nor wholly dead. Both of these famous images arose...

"Stephen Hawking's closest collaborator offers the intellectual superstar's final thoughts on the cosmos-a dramatic revision of the theory that made him the heir to Einstein's legacy. Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. Pondering this mystery led Hawking to study the big bang origin of the universe, but his early work...

Londons fall and kingdoms rise while darkness sweeps the Maresh Empire, and the fraught balance of magic blossoms into dangerous territory while heroes struggle.

"With such compelling and provocative novels as Red Planet Blues, FlashForward and The WWW Trilogy, Robert J. Sawyer has proven himself to be "a writer of boundless confidence and bold scientific extrapolation" (New York Times). Now, the Hugo and Nebula Award-winning author explores the thin line between good and evil that every human being is capable of crossing ... Experimental psychologist Chris Marchuk has developed a flawless technique for identifying...

For Einstein, 1905 was a remarkable year. It was also a miraculous year for the history and future of science. In six short months, he published five papers that would transform our understanding of nature. This unparalleled period is the subject of Rigden's book, which deftly explains what distinguishes 1905 from all other years in the annals of science, and elevates Einstein above all other scientists of the twentieth century.

An account of the century of experimentation that confirmed Einstein's theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory. Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team...
