From the emergence of life at deep-sea vents to solar-powered starships sailing through the galaxy, from the Big Bang to the intricacies of intelligence in many life forms, acclaimed author Ann Druyan documents where humanity has been and where it is going, using her unique gift of bringing complex scientific concepts to life. With evocative photographs and vivid illustrations, she recounts momentous discoveries, from the Voyager missions in which she and her husband, Carl Sagan, participated to Cassini-Huygens's recent insights into Saturn's moons. This breathtaking sequel to Sagan's masterpiece explains how we humans can glean a new understanding of consciousness here on Earth and out in the cosmos--again reminding us that our planet is a pale blue dot in an immense universe of possibility.

    Chanda Prescod-Weinstein shares her love for physics, from the Standard Model of Particle Physics and what lies beyond it, to the physics of melanin in skin, to the latest theories of dark matter — all with a new spin informed by history, politics, and the wisdom of Star Trek.One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly non-traditional, and grounded in Black feminist traditions.Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, sexism, and other dehumanizing systems. She lays out a bold new approach to science and society that begins with the belief that we all have a fundamental right to know and love the night sky. The Disordered Cosmos dreams into existence a world that allows everyone to tap into humanity’s wealth of knowledge about the wonders of the universe.

    For something as elemental as counting and estimating the world around us, it seems like a confusing tool to use. So how did we end up with it?Most of the rest of the world is on the metric system, and for a time in the 1970s America appeared ready to make the switch. Yet it never happened, and the reasons for that get to the root of who we think we are, just as the measurements are woven into the ways we think. John Marciano chronicles the origins of measurement systems, the kaleidoscopic array of standards throughout Europe and the thirteen American colonies, the combination of intellect and circumstance that resulted in the metric system’s creation in France in the wake of the French Revolution, and America’s stubborn adherence to the hybrid United States Customary System ever since. As much as it is a tale of quarters and tenths, it is a human drama, replete with great inventors, visionary presidents, obsessive activists, and science-loving technocrats.Anyone who reads this inquisitive, engaging story will never read Robert Frost’s line “miles to go before I sleep” or eat a foot-long sub again without wondering, Whatever happened to the metric system?

    Astrophysicist Adam Frank traces the question of alien life and intelligence from the ancient Greeks to the leading thinkers of our own time, and shows how we as a civilization can only hope to survive climate change if we recognize what science has recently discovered: that we are just one of ten billion trillion planets in the Universe, and it’s highly likely that many of those planets hosted technologically advanced alien civilizations. What’s more, each of those civilizations must have faced the same challenge of civilization-driven climate change.Written with great clarity and conviction, Light of the Stars builds on the inspiring work of pioneering scientists such as Frank Drake and Carl Sagan, whose work at the dawn of the space age began building the new science of astrobiology; Jack James, the Texas-born engineer who drove NASA’s first planetary missions to success; Vladimir Vernadsky, the Russian geochemist who first envisioned the Earth’s biosphere; and James Lovelock and Lynn Margulis, who invented Gaia theory. Frank recounts the perilous journey NASA undertook across millions of miles of deep space to get its probes to Venus and Mars, yielding our first view of the cosmic laws of planets and climate that changed our understanding of our place in the universe.Thrilling science at the grandest of scales, Light of the Stars explores what may be the largest question of all: What can the likely presence of life on other worlds tell us about our own fate?

    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.

    That collaboration would mark the dawn of modern science . . . and end in murder.Johannes Kepler changed forever our understanding of the universe with his three laws of planetary motion. He demolished the ancient model of planets moving in circular orbits and laid the foundation for the universal law of gravitation, setting physics on the course of revelation it follows to this day. Kepler was one of the greatest astronomers of all time. Yet if it hadn't been for the now lesser-known Tycho Brahe, the man for whom Kepler apprenticed, Kepler would be a mere footnote in today's science books. Brahe was the Imperial Mathematician at the court of the Holy Roman Emperor in Prague and the most famous astronomer of his era. He was one of the first great systematic empirical scientists and one of the earliest founders of the modern scientific method. His forty years of planetary observations—an unparalleled treasure of empirical data—contained the key to Kepler's historic breakthrough. But those observations would become available to Kepler only after Brahe's death. This groundbreaking history portrays the turbulent collaboration between these two astronomers at the turn of the seventeenth century and their shattering discoveries that would mark the transition from medieval to modern science. But that is only half the story. Based on recent forensic evidence (analyzed here for the first time) and original research into medieval and Renaissance alchemy—all buttressed by in-depth interviews with leading historians, scientists, and medical specialists—the authors have put together shocking and compelling evidence that Tycho Brahe did not die of natural causes, as has been believed for four hundred years. He was systematically poisoned—most likely by his assistant, Johannes Kepler. An epic tale of murder and scientific discovery, Heavenly Intrigue reveals the dark side of one of history’s most brilliant minds and tells the story of court politics, personal intrigue, and superstition that surrounded the protean invention of two great astronomers and their quest to find truth and beauty in the heavens above.

    Nearly four decades later, as the world's oldest astronaut, his courage reveted a nation. But these two historical events only bracketed a life that covers the sweep of an extraordinary century.John Glenn's autobiography spans the seminal events of the twentieth century. It is a story that begins with his childhood in Ohio where he learned the importance of family, community, and patriotism. He took these values with him as a marine fighter pilot during World War II and into the skies over Korea, for which he would be decorated. Always a gifted flier, it was during the war that he contemplated the unlimited possibilities of aviation and its frontiers.We see the early days of NASA, where he first served as a backup pilot for astronauts Alan Shepard and Gus Grissom. In 1962 Glenn piloted the Mercury-Atlas 6 Friendship 7 spacecraft on the first manned orbital mission of the United States. Then came several years in international business, followed by a twenty-four year career as a U.S. Senator-and in 1998 a return to space for his remarkable Discover mission at the age of seventy-seven.

    As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

    It contains all of Paine's key works including 'The Rights of Man', his groundbreaking defence of the revolutionary cause in France, 'Common Sense', which won thousands over to the side of the American rebels, and the first part of 'The Age of Reason', a ferocious attack on Christianity. The shorter pieces — on capital punishment, social reform and the abolition of slavery — also confirm the great versatility and power of this master of democratic prose.In their informative introduction, Michael Foot and Isaac Kramnick expore the life, work and influence of Thomas Paine, placing his work in its historical context and illustrating the force and clarity of his literary style.

    The magnetic North Pole will eventually trade places with the South Pole. Satellite evidence suggests to some scientists that the move has already begun, but most still think it won't happen for many decades. All agree that it has happened many times before and will happen again. But this time it will be different. It will be a very bad day for modern civilization.Award-winning science journalist Alanna Mitchell tells in The Spinning Magnet the fascinating history of one of the four fundamental physical forces in the universe, electromagnetism. From investigations into magnetism in thirteenth-century feudal France and the realization six hundred years later in the Victorian era that electricity and magnetism were essentially the same, to the discovery that Earth was itself a magnet, spinning in space with two poles and that those poles aperiodically reverse, this is a utterly engrossing narrative history of ideas and science that readers of Stephen Greenblatt and Sam Kean will love.The recent finding that Earth's magnetic force field is decaying ten times faster than previously thought, portending an imminent pole reversal, ultimately gives this story a spine-tingling urgency. When the poles switch, a process that takes many years, Earth is unprotected from solar radiation storms that would, among other things, wipe out all electromagnetic technology. No satellites, no Internet, no smartphones--maybe no power grid at all. Such potentially cataclysmic solar storms are not unusual. The last one occurred in 2012, and we avoided returning to the Dark Ages only because the part of the sun that erupted happened to be facing away from Earth. One leading US researcher is already drawing maps of the parts of the planet that would likely become uninhabitable.

    The Beatles learn to be brilliant in an hour and a half. An Englishman arrives back from Calcutta but refuses to adjust his watch. Beethoven has his symphonic wishes ignored. A US Senator begins a speech that will last for 25 hours. The horrors of war are frozen at the click of a camera. A woman designs a ten-hour clock and reinvents the calendar. Roger Bannister lives out the same four minutes over a lifetime. And a prince attempts to stop time in its tracks.Timekeepers is a book about our obsession with time and our desire to measure it, control it, sell it, film it, perform it, immortalise it and make it meaningful. It has two simple intentions: to tell some illuminating stories, and to ask whether we have all gone completely nuts.

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.
