    We often overlook the historical link between mathematics and technological advances, says Stewart—but this connection is integral to any complete understanding of human history.Equations are modeled on the patterns we find in the world around us, says Stewart, and it is through equations that we are able to make sense of, and in turn influence, our world. Stewart locates the origins of each equation he presents—from Pythagoras's Theorem to Newton's Law of Gravity to Einstein's Theory of Relativity—within a particular historical moment, elucidating the development of mathematical and philosophical thought necessary for each equation's discovery. None of these equations emerged in a vacuum, Stewart shows; each drew, in some way, on past equations and the thinking of the day. In turn, all of these equations paved the way for major developments in mathematics, science, philosophy, and technology. Without logarithms (invented in the early 17th century by John Napier and improved by Henry Briggs), scientists would not have been able to calculate the movement of the planets, and mathematicians would not have been able to develop fractal geometry. The Wave Equation is one of the most important equations in physics, and is crucial for engineers studying the vibrations in vehicles and the response of buildings to earthquakes. And the equation at the heart of Information Theory, devised by Claude Shannon, is the basis of digital communication today.An approachable and informative guide to the equations upon which nearly every aspect of scientific and mathematical understanding depends, In Pursuit of the Unknown is also a reminder that equations have profoundly influenced our thinking and continue to make possible many of the advances that we take for granted.

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    Although the Hollywood blockbuster was fiction, the real Men in Black have consistently attempted to silence the witnesses of UFO and paranormal phenomena since the 1950s.In The Real Men in Black, author Nick Redfern delves deep into the mysterious world of these mysterious operatives. He reveals their origins and discusses classic cases, previously unknown reports, secret government files, and the many theories that have been presented to explain the mystery.Highlights of The Real Men in Black include:The story of Albert Bender, the first man to claim an encounter with the Men in BlackThe involvement of the MIB in the Mothman saga that dominated the town of Point Pleasant, West Virginia in the 1960sEncounters with the MIB at the site of one of the world's most famous monsters: Loch NessExclusive interviews with leading researchers of the MIB phenomenon

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    The science of complexity studies how single elements, such as a species or a stock, spontaneously organize into complicated structures like ecosystems and economies; stars become galaxies, and snowflakes avalanches almost as if these systems were obeying a hidden yearning for order. Drawing from diverse fields, scientific luminaries such as Nobel Laureates Murray Gell-Mann and Kenneth Arrow are studying complexity at a think tank called The Santa Fe Institute. The revolutionary new discoveries researchers have made there could change the face of every science from biology to cosmology to economics. M. Mitchell Waldrop's groundbreaking bestseller takes readers into the hearts and minds of these scientists to tell the story behind this scientific revolution as it unfolds.

    And two, are there UFOs.” According to Hubbell, “Clinton was dead serious.” The key to unlocking the mystery of President Kennedy’s assassination and a possible UFO connection lie in events that occurred 18 years earlier in post-war Germany. In 1945 John F. Kennedy was a guest of Navy Secretary James Forrestal, where he personally witnessed technological secrets that have still not been disclosed to the world. These secrets stemmed from extraterrestrial technologies that Nazi Germany had acquired and were attempting to use in their weapons programs. In searching for answers to who killed President Kennedy we need to start with the death of his mentor, James Forrestal in 1949. Forrestal became the first Secretary of Defense in 1947, a position he held until March, 1949. Forrestal was a visionary who thought Americans had a right to know about the existence of extraterrestrial life and technologies. Forrestal was sacked by President Truman because he was revealing the truth to various officials, including Kennedy who was a Congressman at the time.Forrestal's ideals and vision inspired Kennedy, and laid the seed for what would happen 12 years later. After winning the 1960 Presidential election, Kennedy learned a shocking truth from President Eisenhower. The control group set up to run highly classified extraterrestrial technologies, the Majestic-12 Group, had become a rogue government agency. Eisenhower warned Kennedy that MJ-12 had to be reined in. It posed a direct threat to American liberties and democratic processes. Kennedy followed Eisenhower’s advice, and set out to realize James Forrestal’s vision. The same forces that orchestrated Forrestal's death, opposed Kennedy's efforts at every turn. When Kennedy was on the verge of succeeding, by forcing the CIA to share classified UFO information with other government agencies on November 12, 1963, he was assassinated ten days later. Kennedy’s Last Stand is the story of how an American President tried to realize his friend and mentor’s vision of a world where humanity openly knows about extraterrestrial life; and of the government officials responsible for denying that vision.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    Like old soldiers everywhere, they are fading away. But these soldiers have an incredible and sometimes shocking story to tell. It certainly does not make for comfortable reading. Secrets which have been bottled up for a lifetime are revealed, stories are told at last and memories which have been hidden away for 60 years finally resurface. These are facets of history's most dreadful war being revealed for the very first time. "The Wehrmacht" is a remarkable personal record of the Third Reich's rise and fall from the inside: of how those responsible for the maelstrom sent their armies to conquer only to see them crushed as the world united against them; of men who were seduced by the siren call of Hitler, only to pay a terribly heavy price. It allows the human stories to unfold within the bigger picture behind the major campaigns of the Second World War - from the early Blitzkrieg successes through the submarine warfare of the Battle of the Atlantic, and the brutal hardships of the Russian Front, to the last days of the Reich and the fall of Berlin. "The Wehrmacht" is a brilliantly researched and thought-provoking book that reveals unique human dimensions of the world's greatest military conflict.

    Building upon that record and the recollections of other F-4G Wild Weasel aircrew, the authors show a slice of what life and war was like during that time. The pawns in the game, the ones that had to actually do the fighting and dying were the hundreds of thousands of men and women who left their homes and families to live for seemingly endless months in the vast, trackless desert while the world stage-play unfolded. To them, the war was deeply personal. At times, the war was scary; at other times, it was funny as hell. Usually, if you survive the former, it turns into the latter.

    She moved from New York to San Francisco, where she landed at a big-data startup in the heart of the Silicon Valley bubble: a world of surreal extravagance, dubious success, and fresh-faced entrepreneurs hell-bent on domination, glory, and, of course, progress.Anna arrived amidst a massive cultural shift, as the tech industry rapidly transformed into a locus of wealth and power rivaling Wall Street. But amid the company ski vacations and in-office speakeasies, boyish camaraderie and ride-or-die corporate fealty, a new Silicon Valley began to emerge: one in far over its head, one that enriched itself at the expense of the idyllic future it claimed to be building.Part coming-age-story, part portrait of an already-bygone era, Anna Wiener’s memoir is a rare first-person glimpse into high-flying, reckless startup culture at a time of unchecked ambition, unregulated surveillance, wild fortune, and accelerating political power. With wit, candor, and heart, Anna deftly charts the tech industry’s shift from self-appointed world savior to democracy-endangering liability, alongside a personal narrative of aspiration, ambivalence, and disillusionment.Unsparing and incisive, Uncanny Valley is a cautionary tale, and a revelatory interrogation of a world reckoning with consequences its unwitting designers are only beginning to understand.

    But what is it physically? And where is it really? Our mental map of the network is as blank as the map of the ocean that Columbus carried on his first Atlantic voyage. The Internet, its material nuts and bolts, is an unexplored territory. Until now.In Tubes, journalist Andrew Blum goes inside the Internet's physical infrastructure and flips on the lights, revealing an utterly fresh look at the online world we think we know. It is a shockingly tactile realm of unmarked compounds, populated by a special caste of engineer who pieces together our networks by hand; where glass fibers pulse with light and creaky telegraph buildings, tortuously rewired, become communication hubs once again. From the room in Los Angeles where the Internet first flickered to life to the caverns beneath Manhattan where new fiber-optic cable is buried; from the coast of Portugal, where a ten-thousand-mile undersea cable just two thumbs wide connects Europe and Africa, to the wilds of the Pacific Northwest, where Google, Microsoft, and Facebook have built monumental data centers—Blum chronicles the dramatic story of the Internet's development, explains how it all works, and takes the first-ever in-depth look inside its hidden monuments.This is a book about real places on the map: their sounds and smells, their storied pasts, their physical details, and the people who live there. For all the talk of the "placelessness" of our digital age, the Internet is as fixed in real, physical spaces as the railroad or telephone. You can map it and touch it, and you can visit it. Is the Internet in fact "a series of tubes" as Ted Stevens, the late senator from Alaska, once famously described it? How can we know the Internet's possibilities if we don't know its parts?Like Tracy Kidder's classic The Soul of a New Machine or Tom Vanderbilt's recent bestseller Traffic, Tubes combines on-the-ground reporting and lucid explanation into an engaging, mind-bending narrative to help us understand the physical world that underlies our digital lives.

    As obvious as the Presidential motorcade, most people assume the squadron is a travel perk for VIPs. They’re only half right: while the helicopters do provide transport, the unit exists to evacuate high-ranking officials in the event of a terrorist or nuclear attack on the capital. In the event of an attack, select officials would be whisked by helicopters to a ring of secret bunkers around Washington, even as ordinary citizens were left to fend for themselves.For sixty years, the US government has been developing secret Doomsday plans to protect itself, and the multibillion-dollar Continuity of Government (COG) program takes numerous forms—from its plans to evacuate the Liberty Bell from Philadelphia to the plans to launch nuclear missiles from a Boeing-747 jet flying high over Nebraska. In Raven Rock, Garrett M. Graff sheds light on the inner workings of the 650-acre compound (called Raven Rock) just miles from Camp David, as well as dozens of other bunkers the government built its top leaders during the Cold War, from the White House lawn to Cheyenne Mountain in Colorado to Palm Beach, Florida, and the secret plans that would have kicked in after a Cold War nuclear attack to round up foreigners and dissidents and nationalize industries. Equal parts a presidential, military, and cultural history, Raven Rock tracks the evolution of the government plan and the threats of global war from the dawn of the nuclear era through the War on Terror.

    Kennedy’s inspiring challenge, and America’s race to the moon.“We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win.”—President John F. KennedyOn May 25, 1961, JFK made an astonishing announcement: his goal of putting a man on the moon by the end of the decade. In this engrossing, fast-paced epic, Douglas Brinkley returns to the 1960s to recreate one of the most exciting and ambitious achievements in the history of humankind. American Moonshot brings together the extraordinary political, cultural, and scientific factors that fueled the birth and development of NASA and the Mercury, Gemini and Apollo projects, which shot the United States to victory in the space race against the Soviet Union at the height of the Cold War.Drawing on new primary source material and major interviews with many of the surviving figures who were key to America’s success, Brinkley brings this fascinating history to life as never before. American Moonshot is a portrait of the brilliant men and women who made this giant leap possible, the technology that enabled us to propel men beyond earth’s orbit to the moon and return them safely, and the geopolitical tensions that spurred Kennedy to commit himself fully to this audacious dream. Brinkley’s ensemble cast of New Frontier characters include rocketeer Wernher von Braun, astronaut John Glenn and space booster Lyndon Johnson.A vivid and enthralling chronicle of one of the most thrilling, hopeful, and turbulent eras in the nation’s history, American Moonshot is an homage to scientific ingenuity, human curiosity, and the boundless American spirit.

    The Uninvited also examines the reaction of governments, and of the scientific community, as well as examining the world's most famous alien contact cases, and highlighting the common threads that bind them together. Nick Pope devotes a significant portion of the book to detailing a number of cases that he investigated personally, before drawing things together by discussing the various theories that might explain what lies behind this fascinating mystery.
