He is known for both his breakthroughs in theoretical physics as well as his ability to make complex concepts accessible for all, and was beloved for his mischievous sense of humor. At the time of his death, Hawking was working on a final project: a book compiling his answers to the "big" questions that he was so often posed--questions that ranged beyond his academic field. Within these pages, he provides his personal views on our biggest challenges as a human race, and where we, as a planet, are heading next. Each section will be introduced by a leading thinker offering his or her own insight into Professor Hawking's contribution to our understanding.

    Nearly a half-century after Neil Armstrong walked on the moon, these Space Barons-most notably Elon Musk and Jeff Bezos, along with Richard Branson and Paul Allen-are using Silicon Valley-style innovation to dramatically lower the cost of space travel, and send humans even further than NASA has gone. These entrepreneurs have founded some of the biggest brands in the world-Amazon, Microsoft, Virgin, Tesla, PayPal-and upended industry after industry. Now they are pursuing the biggest disruption of all: space. Based on years of reporting and exclusive interviews with all four billionaires, this authoritative account is a dramatic tale of risk and high adventure, the birth of a new Space Age, fueled by some of the world's richest men as they struggle to end governments' monopoly on the cosmos. The Space Barons is also a story of rivalry-hard-charging startups warring with established contractors, and the personal clashes of the leaders of this new space movement, particularly Musk and Bezos, as they aim for the moon and Mars and beyond.

    Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that the Universe is accelerating its expansion and that something stronger than gravity--dark energy--is at work. In Einstein's Telescope Evalyn Gates, a University of Chicago astrophysicist, transports us to the edge of contemporary science to explore the revolutionary tool that unlocks the secrets of these little-understood cosmic constituents. Based on Einstein's theory of general relativity, gravitational lensing, or "Einstein's Telescope," is enabling new discoveries that are taking us toward the next revolution in scientific thinking--one that may change forever our notions of where the Universe came from and where it is going.

    The result is the most authoritative and scientifically accurate description of the revolutionary developments taking place in medicine, computers, artificial intelligence, nanotechnology, energy production, and astronautics.In all likelihood, by 2100 we will control computers via tiny brain sensors and, like magicians, move objects around with the power of our minds. Artificial intelligence will be dispersed throughout the environment, and Internet-enabled contact lenses will allow us to access the world's information base or conjure up any image we desire in the blink of an eye.Meanwhile, cars will drive themselves using GPS, and if room-temperature superconductors are discovered, vehicles will effortlessly fly on a cushion of air, coasting on powerful magnetic fields and ushering in the age of magnetism.Using molecular medicine, scientists will be able to grow almost every organ of the body and cure genetic diseases. Millions of tiny DNA sensors and nanoparticles patrolling our blood cells will silently scan our bodies for the first sign of illness, while rapid advances in genetic research will enable us to slow down or maybe even reverse the aging process, allowing human life spans to increase dramatically.In space, radically new ships—needle-sized vessels using laser propulsion—could replace the expensive chemical rockets of today and perhaps visit nearby stars. Advances in nanotechnology may lead to the fabled space elevator, which would propel humans hundreds of miles above the earth's atmosphere at the push of a button.But these astonishing revelations are only the tip of the iceberg. Kaku also discusses emotional robots, antimatter rockets, X-ray vision, and the ability to create new life-forms, and he considers the development of the world economy. He addresses the key questions: Who are the winner and losers of the future? Who will have jobs, and which nations will prosper?All the while, Kaku illuminates the rigorous scientific principles, examining the rate at which certain technologies are likely to mature, how far they can advance, and what their ultimate limitations and hazards are. Synthesizing a vast amount of information to construct an exciting look at the years leading up to 2100, Physics of the Future is a thrilling, wondrous ride through the next 100 years of breathtaking scientific revolution.

    Whether they've arrived via rocket, flying saucer, or plain old teleportation, they've been invading, infiltrating, or inspiring us for decades, and they've fascinated moviegoers and television watchers for more than fifty years. About half of us believe that aliens really exist, and millions are convinced they've visited Earth. For twenty-five years, SETI has been looking for the proof, and as the program's senior astronomer, Seth Shostak explains in this engrossing book, it's entirely possible that before long conclusive evidence will be found. His informative, entertaining report offers an insider's view of what we might realistically expect to discover light-years away among the stars. Neither humanoids nor monsters, says Shostak; in fact, biological intelligence is probably just a precursor to machine beings, enormously advanced artificial sentients whose capabilities and accomplishments may have developed over billions of years and far exceed our own. As he explores what, if anything, they would tell us and what their existence would portend for humankind and the cosmos, he introduces a colorful cast of characters and provides a vivid, state-of-the-art account of the past, present, and future of our search for extraterrestrial intelligence.

    Now in paperback, The Neptune File is the first account of the dramatic events surrounding the discovery of the solar system's eighth planet, and the story of two men who were able to see on paper what astronomers looking through telescopes for 200 years did not.

    The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare in 2012 that physicists has succeeded in creating and identifying this all-important new particle, the discovery was celebrated around the world.And yet, virtually no one who read that news could tell you what, exactly, the Higgs boson was, and why its discovery was so important that we had to spend 10 billion dollars and build the single largest and most complex device in the history of mankind in order to find it. When you understand the details, this story ranks as one of the most thrilling in the history of modern science.Award-winning theoretical physicist Sean Carroll, a brilliant researcher as well as a gifted speaker who excels in explaining scientific concepts to the public, is perfectly positioned to tell this story. In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.You also get an in-depth view of the Large Hadron Collider - the largest machine ever built, and the device responsible for finally revealing the concept of the Higgs boson as reality. By the end, you'll understand how the Higgs boson verifies the final piece in the Standard Model of particle physics, and how its discovery validates and deepens our understanding of the universe.

    But until now, we have known only half the story. With the end of the cold war, decades of secrets have been exposed, bringing with them a remarkable opportunity: the unmasking of the true heroes and villains behind one of the most exciting races in history.At the center of this exhilarating, fast-paced account are Wernher von Braun, the camera-friendly former Nazi scientist who led the American rocket design team, and Sergei Korolev, the chief Soviet designer and former political prisoner whose identity was a closely guarded state secret. These rivals were opposite in every way, save for one: each was obsessed by the idea of launching a man to the Moon. Korolev told his wife, "In every century men were looking into the sky and dreaming. And now I'm close to the greatest dream of mankind."In attempting to fulfill this dream, Korolev was initially hampered by a budget so small that his engineers were forced to repurpose cardboard boxes as drafting tables. Von Braun, meanwhile, was eventually granted almost limitless access to funds by an American government panicked at the thought that their cold war enemy might take the lead in the exploration of space. Korolev, whose family life was destroyed by his long sentence in the Gulag, was constantly aware that any false move would finish his career or even his life. His rival, on the other hand, enjoyed remarkable celebrity in America and was even the subject of a 1960 biopic.In this extraordinary book, Deborah Cadbury combines sheeradventure and nail-biting suspense with a moving portrayal of the space race's human dimension. Using source materials never before seen, she reveals that the essential story of the cold war is a mind-bending voyage beyond the bounds of the Earth, one marked by espionage, ambition, ingenuity, and passion.

    'Astrology must be right,' wrote the American astrologer Evangeline Adams, claimed descendant of John Quincy Adams, in a challenge to skeptics in 1929. 'There can be no appeal from the Infinite.' The Fated Sky explores both the history of astrology & the controversial subject of its historical influence. It's the 1st serious book to fully engage astrology in this way. Astrology is the oldest occult sciences, also the origin of science itself. Astronomy, mathematics & other disciplines arose in part to make possible the calculations necessary in casting horoscopes. For 5000 years, the influence of the stars has been viewed as shaping the course of affairs. According to recent polls, at least 30% of Americans believe in it, tho modern astrology is utterly different from the doctrine of the stars that won the respect & allegiance of the greatest thinkers, scientists & writers--Greek, Roman, Egyptian, Arab & Persian--of earlier days. Statesmen, popes & kings once embraced it. Th Aquinas found it compatible with Xian faith. There are some 200 allusions to it in Shakespeare's plays, all their predictions fulfilled. The great astronomers of the scientific revolution--Copernicus, Tycho Brahe, Kepler--were adherents. Newton's appetite for mathematics was whetted by an astrological text. Prominent figures such as Churchill, deGaulle & Reagan have consulted astrologers, heeding their advice. Universities as diverse as Oxford & Spain's Univ. of Zaragoza offer courses in the subject, fulfilling Jung's prediction that astrology would again become the subject of serious discourse. Whether astrology actually has the powers ascribed to it is open to debate. But there's no doubt that it maintains a hold on the human mind. The Fated Sky gives a comprehensive account of this subject & its enduring influence on history & the history of ideas.

    Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.
