A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    Yes, all those years you were told not to sit too close to the television (you'll hurt your eyes!) or swallow your gum (it stays in your stomach for seven years!) or crack your knuckles (arthritis!) are called into question by our country's leading trivia guru. Jennings separates myth from fact to debunk a wide variety of parental edicts: no swimming after meals, sit up straight, don't talk to strangers, and so on. Armed with medical case histories, scientific findings, and even the occasional experiment on himself (or his kids), Jennings exposes countless examples of parental wisdom run amok. Whether you're a parent who wants to know what you can stop worrying about or a kid (of any age) looking to say, "I told you so,"; this is the anti-helicopter parenting book you've been waiting for.

    It's all too easy to ignore the fascinating possibilities of emptiness and non-existence, and we may well wonder what there is to say about nothing. But scientists have known for centuries that nothing is the key to understanding absolutely everything, from why particles have mass to the expansion of the universe - so without nothing we'd be precisely nowhere.Absolute zero (the coldest cold that can exist) and the astonishing power of placebos, light bulbs, superconductors, vacuums, dark energy, 'bed rest' and the birth of time - all are different aspects of the concept of nothing. The closer we look, the bigger the subject gets. Why do some animals spend all day doing nothing? What happens in our brains when we try to think about nothing? With chapters by 20 science writers, including top names such as Ian Stewart, Marcus Chown, Nigel Henbest, Michael Brooks, Paul Davies and David Fisher, this fascinating and intriguing book revels in a subject that has tantalised the finest minds for centuries, and shows there's more to nothing than meets the eye.

    Even after more than three centuries and the revolutions of Einsteinian relativity and quantum mechanics, Newtonian physics continues to account for many of the phenomena of the observed world, and Newtonian celestial dynamics is used to determine the orbits of our space vehicles.This completely new translation, the first in 270 years, is based on the third (1726) edition, the final revised version approved by Newton; it includes extracts from the earlier editions, corrects errors found in earlier versions, and replaces archaic English with contemporary prose and up-to-date mathematical forms. Newton's principles describe acceleration, deceleration, and inertial movement; fluid dynamics; and the motions of the earth, moon, planets, and comets. A great work in itself, the Principia also revolutionized the methods of scientific investigation. It set forth the fundamental three laws of motion and the law of universal gravity, the physical principles that account for the Copernican system of the world as emended by Kepler, thus effectively ending controversy concerning the Copernican planetary system.The illuminating Guide to the Principia by I. Bernard Cohen, along with his and Anne Whitman's translation, will make this preeminent work truly accessible for today's scientists, scholars, and students.

    Described on the book jacket as an "autodidact extraordinaire," Zacks is also the author of History Laid Bare, making him something of an expert guide through history's back alleys and side streets. There's no fact too seamy or perverse for Zacks to drag out into the light of day, from matters scatological and sexual to some of history's most truly bizarre episodes. Curious about ancient nose-blowing etiquette? What about the sexual proclivities of Catherine the Great? Throughout chapters such as "The Evolution of Underwear" and "Dentistry Before Novocaine," Zacks proves a tireless debunker of popular myths as well as a muckraker par excellence.

    Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

    Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own? Ananthaswamy soon finds himself at the ends of the earth--in remote and sometimes dangerous places. Take the Atacama Desert in the Chilean Andes, one of the coldest, driest places on the planet, where not even a blade of grass can survive. Its spectacularly clear skies and dry atmosphere allow astronomers to gather brilliant images of galaxies billions of light-years away. Ananthaswamy takes us inside the European Southern Observatory's Very Large Telescope on Mount Paranal, where four massive domes open to the sky each night "like dragons waking up."He also takes us deep inside an abandoned iron mine in Minnesota, where half-mile-thick rock shields physicists as they hunt for elusive dark matter particles. And to the East Antarctic Ice Sheet, where engineers are drilling 1.5 miles into the clearest ice on the planet. They're building the world's largest neutrino detector, which could finally help reconcile quantum physics with Einstein's theory of general relativity.The stories of the people who work at these and other dramatic research sites--from Lake Baikal in Siberia to the Indian Astronomical Observatory in the Himalayas to the subterranean lair of the Large Hadron Collider--make for a compelling new portrait of the universe and our quest to understand it. An atmospheric, engaging, and illuminating read, "The Edge of Physics" depicts science as a human process, bringing cosmology back down to earth in the most vivid terms.

    It was studied from antiquity to the Renaissance as a way of glimpsing the nature of reality. Geometry is number in space; music is number in time; and comology expresses number in space and time. Number, music, and geometry are metaphysical truths: life across the universe investigates them; they foreshadow the physical sciences.Quadrivium is the first volume to bring together these four subjects in many hundreds of years. Composed of six successful titles in the Wooden Books series-Sacred Geometry, Sacred Number, Harmonograph, The Elements of Music, Platonic & Archimedean Solids, and A Little Book of Coincidence-it makes ancient wisdom and its astonishing interconnectedness accessible to us today.Beautifully produced in six different colors of ink, Quadrivium will appeal to anyone interested in mathematics, music, astronomy, and how the universe works.

    The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit.Now with the advent of a revolutionary new plan, all this has changed. leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes.The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars--a process that can alter the atmosphere of planets and pave the way for sustainable life.

    Now, two of the world's most eminent thinkers -- University of London physicists David Bohm, a former protege of Einstein's and one of the world's most respected quantum physicists, and Stanford neurophysiologist Karl Pribram, one of the architects of our modern understanding of the brain -- believe that the universe itself may be a giant hologram, quite literally a kind of image or construct created, at least in part, by the human mind. This remarkable new way of looking at the universe explains not only many of the unsolved puzzles of physics, but also such mysterious occurrences as telepathy, out-of-body and near death experiences, "lucid" dreams, and even religious and mystical experiences such as feelings of cosmic unity and miraculous healings.

    Beginning with the Big Bang, David Christian views the interaction of the natural world with the more recent arrivals in flora and fauna, including human beings.Cosmology, geology, archeology, and population and environmental studies—all figure in David Christian's account, which is an ambitious overview of the emerging field of "Big History." Maps of Time opens with the origins of the universe, the stars and the galaxies, the sun and the solar system, including the earth, and conducts readers through the evolution of the planet before human habitation. It surveys the development of human society from the Paleolithic era through the transition to agriculture, the emergence of cities and states, and the birth of the modern, industrial period right up to intimations of possible futures. Sweeping in scope, finely focused in its minute detail, this riveting account of the known world, from the inception of space-time to the prospects of global warming, lays the groundwork for world history—and Big History—true as never before to its name.

    Through that observation, astronomers could calculate the size of the solar system—but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Overcoming incredible odds and political strife, astronomers from Britain, France, Russia, Germany, Sweden, and the American colonies set up observatories in remote corners of the world, only to have their efforts thwarted by unpredictable weather and warring armies. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.   Chasing Venus brings to life the personalities of the eighteenth-century astronomers who embarked upon this complex and essential scientific venture, painting a vivid portrait of the collaborations, the rivalries, and the volatile international politics that hindered them at every turn. In the end, what they accomplished would change our conception of the universe and would forever alter the nature of scientific research.

    The world's foremost expert on the English language takes us on an entertaining and eye-opening tour of the history of our vernacular through the ages.In this entertaining history of the world's most ubiquitous language, David Crystal draws on one hundred words that best illustrate the huge variety of sources, influences and events that have helped to shape our vernacular since the first definitively English word — ‘roe’ — was written down on the femur of a roe deer in the fifth century.Featuring ancient words ('loaf'), cutting edge terms that reflect our world ('twittersphere'), indispensable words that shape our tongue ('and', 'what'), fanciful words ('fopdoodle') and even obscene expressions (the "c word"...), David Crystal takes readers on a tour of the winding byways of our language via the rude, the obscure and the downright surprising.
