Описание: The authoritative story of the headline-making discovery of gravitational waves by an eminent theoretical astrophysicist and award-winning writer.
From the author of "How the Universe Got Its Spots "and "A Madman Dreams of Turing Machines, " the epic story of the scientific campaign to record the soundtrack of our universe. Black holes are dark. That is their essence. When black holes collide, they will do so unilluminated. Yet the black hole collision is an event more powerful than any since the origin of the universe. The profusion of energy will emanate as waves in the shape of spacetime: gravitational waves. No telescope will ever record the event; instead, the only evidence would be the sound of spacetime ringing. In 1916, Einstein predicted the existence of gravitational waves, his top priority after he proposed his theory of curved spacetime. One century later, we are recording the first sounds from space, the soundtrack to accompany astronomy s silent movie. In "Black Hole Blues and Other Songs from Outer Space, " Janna Levin recounts the fascinating story of the obsessions, the aspirations, and the trials of the scientists who embarked on an arduous, fifty-year endeavor to capture these elusive waves. An experimental ambition that began as an amusing thought experiment, a mad idea, became the object of fixation for the original architects Rai Weiss, Kip Thorne, and Ron Drever. Striving to make the ambition a reality, the original three gradually accumulated an international team of hundreds. As this book was written, two massive instruments of remarkably delicate sensitivity were brought to advanced capability. As the book draws to a close, five decades after the experimental ambition began, the team races to intercept a wisp of a sound with two colossal machines, hoping to succeed in time for the centenary of Einstein s most radical idea. Janna Levin s absorbing account of the surprises, disappointments, achievements, and risks in this unfolding story offers a portrait of modern science that is unlike anything we ve seen before."

Описание: In the early 1990s, people predicted the death of privacy, an end to the current concept of "property," a paperless society, 500 channels of high-definition interactive television, world peace, and the extinction of the human race after a takeover engineered by intelligent machines. Imagining the Internet zeroes in on predictions about the Internet's future and revisits past predictions-and how they turned out-to put that imagined future in perspective. Interlaced with revealing analysis, this compendium of thoughts from stakeholders and skeptics, from George Orwell, Marshall McLuhan, and Isaac Asimov to Bill Gates, Bruce Sterling, Nicholas Negroponte, Al Gore, and many others, combines history and biography with future visions and a look at the social, political, and economic consequences of new communication technology. It also gives the history of communications in a nutshell, illustrating the serious impact of pervasive networks and how they will change our lives over the next century.
