Time travel has been a common feature in popular science fiction, but with today''s understanding of black holes, it could possibly be a reality. Many astrophysicists believe black holes can function as tunnels leading to other times and other places and that they contain the key to the Big Bang.

“An elegant and accessible” investigation of quantum mechanics—“highly recommended” for students of the sciences, sci-fi fans, and anyone interested in the strange world of quantum physics (Forbes) Rules of the quantum world seem to say that a cat can be both alive and dead at the same time and a particle can be in two places at once. And that particle is also a wave; everything in the quantum world can described in terms of waves—or entirely in terms of particles. These interpretations were all established by the end of the 1920s, by Erwin Schrödinger, Werner Heisenberg, Paul Dirac, and others. But no one has yet come up with a commonsense explanation of what is going on. In this concise and engaging book, astrophysicist John Gribbin offers an overview of six of the leading interpretations of quantum mechanics. Gribbin calls his account “agnostic,” explaining that none of these interpretations is any better—or any worse—than any of the others. Gribbin presents: • The Copenhagen Interpretation, promoted by Niels Bohr and named by Heisenberg • The Pilot-Wave Interpretation, developed by Louis de Broglie • The Many Worlds Interpretation • The Decoherence Interpretation • The Ensemble “Non-Interpretation” • The Timeless Transactional Interpretation, which theorized waves going both forward and backward in time All of these interpretations are crazy, Gribbin warns, and some are more crazy than others—but in the quantum world, being more crazy does not necessarily mean more wrong.

The quantum computer is no longer the stuff of science fiction. Pioneering physicists are on the brink of unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schrödinger''s famous "dead and alive" cat, rely on entities like electrons, photons, or atoms existing in two states at the same time - is set to turn the computing world on its head. In his fascinating study of this cutting-edge technology, and featuring a new introduction, John Gribbin explores the nature of quantum reality, arguing for a universe of many parallel worlds where "everything is real." Looking back to Alan Turing''s work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through "intuition" and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to create a world where communication occurs faster than light and teleportation is possible. This is an exciting insider''s look at the new frontier of computer science and its revolutionary implications.

Admiral FitzRoy made his name as a captain on the HMS Beagle. It was for his second voyage on the ship (1831-36) that he decided to ask Charles Darwin to accompany him, and it was during this time that Darwin began to develop the ideas that would lead him to his theory of evolution by natural selection. But FitzRoy was not just ''Darwin''s captain'': he was an MP, he was the second Governor of New Zealand from 1843-45 when he made himself unpopular with the settlers by upholding Maori rights, and in 1854 he set up the Meteorological Office which made the lives of all sailors who came after him so much safer. John and Mary Gribbin''s portrait of this multi-talented man whose impact on modern life is still felt will fascinate all who read it.

Time travel is a familiar theme of science fiction, but is it really possible? Surprisingly, time travel is not forbidden by the laws of physics - and John Gribbin argues that if it is not impossible then it must be possible. Gribbin brilliantly illustrates the possibilities of time travel by comparing familiar themes from science fiction with their real-world scientific counterparts, including Einstein''s theories of relativity, black holes, quantum physics, and the multiverse, illuminated by examples from the fictional tales of Robert Heinlein, Larry Niven, Carl Sagan and others. The result is an entertaining guide to some deep mysteries of the Universe which may leave you wondering whether time actually passes at all, and if it does, whether we are moving forwards or backwards. A must-read for science fiction fans and anyone intrigued by deep science.

2005 marks the 100th anniversary of Einstein''s three papers which were the basis for the Theory of Relativity, and that are referred to in the science community as the "Annus Mirabilis."
