Böcker av David Toomey

"For readers of Inside of a Dog and The Soul of an Octopus, a fascinating, charming, and revelatory look at the science behind why animals play that shows how life-at its most fundamental level-is playful. In Kingdom of Play, critically acclaimed science writer David Toomey takes us on a fast-paced and entertaining tour of playful animals and the scientists who study them. From octopuses on Australia's Great Barrier Reef to meerkats in the Kalahari Desert to brown bears on Alaska's Aleutian Islands, we follow adventurous researchers as they design and conduct experiments seeking answers to new, intriguing questions: When did play first appear in animals? How does play develop the brain, and how did it evolve? Are the songs and aerial acrobatics of birds the beginning of avian culture? Is fairness in dog play the foundation of canine ethics? And does play direct and possibly accelerate evolution? Monkeys belly-flop, dolphins tail-walk, elephants mud-slide, crows dive-bomb, and octopuses bounce balls. These activities are various, but all are play, and as Toomey explains, animal play can be seen as a distinct behavior-one that is ongoing and open-ended, purposeless and provisional-rather like natural selection. Through a close examination of both natural selection and play, Toomey argues that life itself is fundamentally playful. A globe-spanning journey and a scientific detective story filled with lively animal anecdotes, Kingdom of Play is an illuminating-and yes, playful-look at a little-known aspect of the animal kingdom"--

Since H. G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.
