It looks at what makes immortality appear so attractive and at the possibility that we would be better served with longer lives and the freedom to terminate our lives at the time when life has given us all the joy, inspiration and personal development it possibly could.
What If We Don’t Die?
- Presents major moral dilemmas associated with human immortality, something which seems imminent due to rapidly progressing biomedical research.
- Touches on big questions: is it acceptable that the immortal generation will be the last? How much life do you want? What is the purpose of life if life never ends?
- Will trigger your imagination by putting a new spin on free will, current concepts of time and eternity, the possibility of multiple universes and multiple yous.
What If We Don’t Die? draws extensively on philosophical and religious thought on the purpose of life and introduces novel perspectives on existence, personality and immortality based, for instance, on quantum mechanics and multiverse theory.
The contributions present a comprehensive overview of European efforts in a broad range of areas including energy, culture, science, and security; access to space, space applications, human spaceflight, security and space situational awareness, and strategic issues. They make a cogent strategic and economic case for policy makers to continue to bear in mind the importance of autonomous space capabilities, even in an interdependent globalised world.
On a winter day in 1903, in the Outer Banks of North Carolina, two brothers—bicycle mechanics from Dayton, Ohio—changed history. But it would take the world some time to believe that the age of flight had begun, with the first powered machine carrying a pilot.
Orville and Wilbur Wright were men of exceptional courage and determination, and of far-ranging intellectual interests and ceaseless curiosity. When they worked together, no problem seemed to be insurmountable. Wilbur was unquestionably a genius. Orville had such mechanical ingenuity as few had ever seen. That they had no more than a public high school education and little money never stopped them in their mission to take to the air. Nothing did, not even the self-evident reality that every time they took off, they risked being killed.
In this “enjoyable, fast-paced tale” (The Economist), master historian David McCullough “shows as never before how two Ohio boys from a remarkable family taught the world to fly” (The Washington Post) and “captures the marvel of what the Wrights accomplished” (The Wall Street Journal). He draws on the extensive Wright family papers to profile not only the brothers but their sister, Katharine, without whom things might well have gone differently for them. Essential reading, this is “a story of timeless importance, told with uncommon empathy and fluency…about what might be the most astonishing feat mankind has ever accomplished…The Wright Brothers soars” (The New York Times Book Review).
Gene Kranz was present at the creation of America’s manned space program and was a key player in it for three decades. As a flight director in NASA’s Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race. He helped to launch Alan Shepard and John Glenn, then assumed the flight director’s role in the Gemini program, which he guided to fruition. With his teammates, he accepted the challenge to carry out President John F. Kennedy’s commitment to land a man on the Moon before the end of the 1960s.
Kranz recounts these thrilling historic events and offers new information about the famous flights. What appeared as nearly flawless missions to the Moon were, in fact, a series of hair-raising near misses. When the space technology failed, as it sometimes did, the controllers’ only recourse was to rely on their skills and those of their teammates. He reveals behind-the-scenes details to demonstrate the leadership, discipline, trust, and teamwork that made the space program a success.
A fascinating firsthand account by a veteran mission controller of one of America’s greatest achievements, Failure is Not an Option reflects on what has happened to the space program and offers his own bold suggestions about what we ought to be doing in space now.
Millions of words have poured forth about man's trip to the moon, but until now few people have had a sense of the most engrossing side of the adventure; namely, what went on in the minds of the astronauts themselves - in space, on the moon, and even during certain odysseys on earth. It is this, the inner life of the astronauts, that Tom Wolfe describes with his almost uncanny empathetic powers, that made The Right Stuff a classic.
From one of our leading technology thinkers and writers, a guide through the twelve technological imperatives that will shape the next thirty years and transform our lives
Much of what will happen in the next thirty years is inevitable, driven by technological trends that are already in motion. In this fascinating, provocative new book, Kevin Kelly provides an optimistic road map for the future, showing how the coming changes in our lives—from virtual reality in the home to an on-demand economy to artificial intelligence embedded in everything we manufacture—can be understood as the result of a few long-term, accelerating forces. Kelly both describes these deep trends—interacting, cognifying, flowing, screening, accessing, sharing, filtering, remixing, tracking, and questioning—and demonstrates how they overlap and are codependent on one another. These larger forces will completely revolutionize the way we buy, work, learn, and communicate with each other. By understanding and embracing them, says Kelly, it will be easier for us to remain on top of the coming wave of changes and to arrange our day-to-day relationships with technology in ways that bring forth maximum benefits. Kelly’s bright, hopeful book will be indispensable to anyone who seeks guidance on where their business, industry, or life is heading—what to invent, where to work, in what to invest, how to better reach customers, and what to begin to put into place—as this new world emerges.

Eugene Cernan was a unique American who came of age as an astronaut during the most exciting and dangerous decade of spaceflight. His career spanned the entire Gemini and Apollo programs, from being the first person to spacewalk all the way around our world to the moment when he left man's last footprint on the Moon as commander of Apollo 17.
Between those two historic events lay more adventures than an ordinary person could imagine as Cernan repeatedly put his life, his family and everything he held dear on the altar of an obsessive desire. Written with New York Times bestselling author Don Davis, The Last Man on the Moon is the astronaut story never before told - about the fear, love and sacrifice demanded of the few men who dared to reach beyond the heavens for the biggest prize of all - the Moon.

It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We’ll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.
The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters—from terrorist attacks to meteor strikes—all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to “terraform” Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.
In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We’ll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.
Before 1955, the concept of an artificial satellite had been demonstrated only on paper. The first nation to transform theory into practice would gain advantages in science, the Cold War propaganda contest, and the military balance of power. Visionaries such as America’s Wernher von Braun and Russia’s Sergey Korolev knew these fields of endeavor would be affected by the launch of a satellite. Moved by patriotism, inquisitiveness, and pride, people on both sides of the Iron Curtain put forth heroic efforts to make that first satellite possible.
Some aspects of this story, like the Navy’s NOTSNIK satellite project, are almost unknown. Even some details of well-known programs, such as the appearance of America’s pioneering Explorer 1 satellite and the contributions made by its rival, Project Vanguard, are generally misremembered. In this book, authors Matt Bille and Erika Lishock tell the whole story of the first space race. They trace the tale from the origins of spaceflight theory and through the military and political events that engendered the all-out efforts needed to turn dreams into reality and thus shape the modern world.
How do companies know how to grow? How can they create products that they are sure customers want to buy? Can innovation be more than a game of hit and miss? Harvard Business School professor Clayton Christensen has the answer. A generation ago, Christensen revolutionized business with his groundbreaking theory of disruptive innovation. Now, he goes further, offering powerful new insights.
After years of research, Christensen has come to one critical conclusion: our long held maxim—that understanding the customer is the crux of innovation—is wrong. Customers don’t buy products or services; they "hire" them to do a job. Understanding customers does not drive innovation success, he argues. Understanding customer jobs does. The "Jobs to Be Done" approach can be seen in some of the world’s most respected companies and fast-growing startups, including Amazon, Intuit, Uber, Airbnb, and Chobani yogurt, to name just a few. But this book is not about celebrating these successes—it’s about predicting new ones.
Christensen contends that by understanding what causes customers to "hire" a product or service, any business can improve its innovation track record, creating products that customers not only want to hire, but that they’ll pay premium prices to bring into their lives. Jobs theory offers new hope for growth to companies frustrated by their hit and miss efforts.
This book carefully lays down Christensen’s provocative framework, providing a comprehensive explanation of the theory and why it is predictive, how to use it in the real world—and, most importantly, how not to squander the insights it provides.
This is the first book to fully describe the Apollo guidance computer’s architecture, instruction format and programs used by the astronauts. As a comprehensive account, it will span the disciplines of computer science, electrical and aerospace engineering. However, it will also be accessible to the ‘space enthusiast’. In short, the intention is for this to be the definitive account of the Apollo guidance computer.
Frank O’Brien’s interest in the Apollo program began as a serious amateur historian. About 12 years ago, he began performing research and writing essays for the Apollo Lunar Surface Journal, and the Apollo Flight Journal. Much of this work centered on his primary interests, the Apollo Guidance Computer (AGC) and the Lunar Module. These Journals are generally considered the canonical online reference on the flights to the Moon. He was then asked to assist the curatorial staff in the creation of the Cradle of Aviation Museum, on Long Island, New York, where he helped prepare the Lunar Module simulator, a LM procedure trainer and an Apollo space suit for display. He regularly lectures on the Apollo computer and related topics to diverse groups, from NASA's computer engineering conferences, the IEEE/ACM, computer festivals and university student groups.

BUT THE FIRST TO DANCE ON IT.
HE WAS THE ROCKETMAN.
For Pete Conrad, it was all about the ride. Whether he was hot-dogging at Mach 2, test-flying every supersonic jet the Navy developed (and some they shouldn’t have), orbiting the Earth at almost 20,000 mph, or redlining his Corvette, he loved pushing the envelope.
Pete wasn’t the squeaky-clean astronaut poster boy. The guy every NASA pilot wanted to happy-hour with after work—and would kill to fly with—Pete had a natural outspokenness that got him washed out of the Mercury program. But the “Comeback Kid” came roaring back—flying two Gemini missions, walking on the Moon as commander of Apollo 12, commanding the first Skylab, and logging more time in space than all the original astronauts combined.
This is a surprisingly candid insider’s view of the greatest ride in history: America’s glorious race to the stars, as seen through the eyes of a real space cowboy.
In 1963, a young reporter for Time-Life named James Schefter was given a dream job: cover America's race to the moon. Since the astronauts were under contract to Life for their stories, Schefter was given complete access to the biggest players at NASA. But at the time, his primary role was to excite the public about the new, expensive, experimental space program, and he couldn't write about everything he saw. In The Race, he does.
From drunken astronaut escapades to near disasters to ferocious political battles, the race to the moon was anything but the smooth process it appeared. There were vicious fights between the engineers, feuds and practical jokes, near-fatal accidents, and dozens of brave, smart, and colorful characters pulling off the greatest exploration in the history of humankind. Like Undaunted Courage and D-Day, this is a tale of achieving the extraordinary against extraordinary odds. As incredible as the "official" story of the space program is, the true, behind-the-scenes tale is more thrilling, more entertaining, and ultimately more ennobling.

“The Eagle has landed.”
When Apollo 11 touched down on the moon’s surface in 1969, the first man on the moon became a legend. In First Man, Hansen explores the life of Neil Armstrong. Based on over fifty hours of interviews with the intensely private Armstrong, who also gave Hansen exclusive access to private documents and family sources, this “magnificent panorama of the second half of the American twentieth century” (Publishers Weekly, starred review) is an unparalleled biography of an American icon.
Upon his return to earth, Armstrong was honored and celebrated for his monumental achievement. He was also—as James R. Hansen reveals in this fascinating and important biography—misunderstood. Armstrong’s accomplishments as engineer, test pilot, and astronaut have long been a matter of record, but Hansen’s unprecedented access to private documents and unpublished sources and his interviews with more than 125 subjects (including more than fifty hours with Armstrong himself) yield this first in-depth analysis of an elusive American celebrity still renowned the world over.
In a riveting narrative filled with revelations, Hansen vividly recreates Armstrong’s career in flying, from his seventy-eight combat missions as a naval aviator flying over North Korea to his formative transatmospheric flights in the rocket-powered X-15 to his piloting Gemini VIII to the first-ever docking in space. These milestones made it seem, as Armstrong’s mother Viola memorably put it, “as if from the very moment he was born—farther back still—that our son was somehow destined for the Apollo 11 mission.”
For a pilot who cared more about flying to the Moon than he did about walking on it, Hansen asserts, Armstrong’s storied vocation exacted a dear personal toll, paid in kind by his wife and children. For the forty-five years since the Moon landing, rumors have swirled around Armstrong concerning his dreams of space travel, his religious beliefs, and his private life.
In a penetrating exploration of American hero worship, Hansen addresses the complex legacy of the First Man, as an astronaut and as an individual. In First Man, the personal, technological, epic, and iconic blend to form the portrait of a great but reluctant hero who will forever be known as history’s most famous space traveler.
Why did NASA managers, who not only had all the information prior to the launch but also were warned against it, decide to proceed? In retelling how the decision unfolded through the eyes of the managers and the engineers, Vaughan uncovers an incremental descent into poor judgment, supported by a culture of high-risk technology. She reveals how and why NASA insiders, when repeatedly faced with evidence that something was wrong, normalized the deviance so that it became acceptable to them. In a new preface, Vaughan reveals the ramifications for this book and for her when a similar decision-making process brought down NASA's Space Shuttle Columbia in 2003.
(QMS) standards for the aerospace industry, are written in the most ambiguous
language possible. Indeed, they don’t outline how they should be implemented.
Those decisions are left to the organization implementing their requirements
or, in some cases, to a consultant.
Although some consultant firms for aerospace systems are
excellent, there are many that purport to be experts yet proffer systems and
processes that are either in contravention to the standards’ requirements or so
unwieldy that they render the process impotent.
In an effort to simplify these issues, this book proposes
practices that have been described as opportunities for improvement or best
practices by registration auditors in the past. It includes a discussion of
each of the three standards’ clauses, suggests best practices to comply with
them, outlines common findings associated with them, and provides an overview
of the changes to AS9100C from AS9100B.
In the first three chapters the authors briefly review the great explosions that will form the subject matter of the book--namely, supernovae and gamma-ray bursters. They describe the very early universe, after the Big Bang, and then how "the lights came on all over the universe as the very first stars began to shine." The importance of stellar mass in governing not only the lifetime of a star (the most massive stars live relatively short lives) but also the way in which a star ends its days is also explained.
Chapter 4 describes the explosion of certain massive stars, outlining the various stages at the end of these stars' lives, which result in the cataclysmic explosions known as supernovae. In Chapter 5 the authors introduce the more exotic and spectacular forms of stellar explosion known as gamma-ray bursters. Chapter 6 studies the markers used for cosmic surveys and Hubble's contributions to the field. The penultimate chapter looks at the very distant, highly luminous sources known as quasars and the evolution of our universe from the earliest times. The final chapter shows how observations of distant supernovae have revealed that the expansion of the universe is in fact accelerating--one of the most exciting and remarkable discoveries in recent years. It was this discovery that lead to the idea that 70% of the universe is made up of mysterious dark energy.
Until around ten years ago, the only planets that we knew about were within the Solar System. The first genuine planet beyond the confines of the Solar System was discovered only 1988. Since then another 350 or so exoplanets have been detected by various methods, and most of these haven been found in the last ten years. Although many more exoplanets discoveries may be expected to occur even as this book is being read, a large enough data set is now available to form the basis for an informed general account of exoplanets.
The topic hence is an extremely "hot" one - all the more so because the recently launched Kepler spacecraft should soon start uncovering many more exoplanets, some perhaps comparable with the Earth (and therefore possibly alternative homes for mankind, if we could ever reach them). Exoplanets: Finding, Exploring, and Understanding Alien Life gives a comprehensive, balances, and above all accurate account of exoplanets.
In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes – all based on current physics – and the challenges they present to physicists, engineers, and space exploration entrepreneurs.
This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek’s ‘warp drive’) and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.
The fifth edition of this successful undergraduate textbook has been extensively modernized and extended in the parts dealing with the Milky Way, extragalactic astronomy and cosmology as well as with extrasolar planets and the solar system (as a consequence of recent results from satellite missions and the new definition by the International Astronomical Union of planets, dwarf planets and small solar-system bodies). Furthermore a new chapter on astrobiology has been added.
Long considered a standard text for physical science majors, Fundamental Astronomy is also an excellent reference and entrée for dedicated amateur astronomers.
Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Opportunity rover in 2012, this eBook, Exploring Mars: Secrets of the Red Planet, traces Scientific American's coverage of the observation and exploration of Mars. The first section outlines early 20th century theories about Mars, including the possibility of an intricate canal system built by an intelligent species. Once the space probes enter the picture, most of those ideas were debunked, but even more questions arose. The second section covers current missions, which found evidence of ancient oceans and a thicker atmosphere that has since been lost. The third section raises even more exciting possibilities with ambitious plans for future missions. In this book, you'll follow these advances in astronomy and planetary science as better and better technology brings us incrementally closer to unlocking the secrets of Mars.

The book is divided into four parts. The first chapter in Part I describes the race for stratospheric passenger travel, the story of the Comet 1, and the loss of G-ALYP and G-ALYY, as well as fatigue design and testing today. The second chapter continues with the transatlantic race and the limits of commercial long distance flight, including information on Steve Fossett and the Virgin Atlantic Global Flyer as well as stratospheric balloon flight. Chapter 3 looks at Concorde and the design challenges of high altitude passenger transport, including Space Shuttle maneuvers in the stratosphere. This part ends with an analysis of airspeed margins in stratospheric flight, as well as flight in low density air and jet engine operation, including stalling, at high altitude.
Part II opens with a chapter on the design considerations for emergency descents. Chapter 6 looks at unpressurized flight, as well as gliding, in the stratosphere, while the following chapter considers hypoxia and its effects. The remaining two chapters in this part consider cabin air systems, the cost of air conditioning, ice at high altitude, and the short and long term health effects of stratospheric flight on air- and cabin crew.
The first two chapters in Part III look at outside the airplane: the weather, tropical storms, temperature shears, and clear air turbulence. The environmental impact of stratospheric flight is considered, including the effect on the ozone layer and the use of biofuels at low temperatures. Part IV looks at the way ahead and considers flight in the upper stratosphere, commercial suborbital flights, and unmanned missions to the stratosphere. The book ends with an analysis of the future of stratospheric flight.
This book thus shows that, beyond the solved and unsolved design riddles and forensic engineering efforts to understand flaws, the modern stratospheric airliner is an incomparably complex, wondrous and awe-inspiring engineering achievement.
Probably the most exciting tether concept is the space elevator, consisting of an incredibly strong long cable that stretches from the Earth’s surface into space. Solar powered "climber" machines, which are already under development, could use such a cable to haul cargo into orbit. The author also describes how space tethers can change the orbit of satellites, by effectively moving their center of gravity through the deployment of long cables. Tethers rotating at high speed can be used to accelerate or slow down spacecraft that briefly latch to them. In principle, such "momentum exchange" tethers can be used to fly a space probe from low Earth orbit all the way into orbit around Mars, without the need for rocket propulsion. A tether can also provide scientific information on the magnetosphere of the planet it’s orbiting.
Michel van Pelt explains the principle of space tethers: what they are and how they can be used in space. He introduces non-technical space enthusiasts to the various possibilities of space tethers, the technological challenges, the potential benefits and their feasibility. He illustrates how, because of their inherent simplicity, space tethers have the potential to make space travel much cheaper, while ongoing advances in tether material technology may make even seemingly far-fetched ideas a reality in the not too distant future.
The equations of motion receive a very full treatment, including the effects of the curvature and rotation of the Earth and distortional motion. Complete chapters are given to human pilots and handling qualities and to flight in turbulence, with numerical examples for a jet transport. Small-perturbation equations for longitudinal and lateral motion appear in convenient matrix forms, both in time-domain and Laplace transforms, dimensional and nondimensional.
After two introductory chapters on the simplifying assumptions demanded for the study and a final chapter on vectors, the author treats the material in four fairly well-defined parts: (1) two-dimensional aerofoils (two-dimensional motion, rectilinear vortices, the circular cylinder as an aerofoil, Joukowski's transformation, theory of two-dimensional aerofoils, and thin aerofoils); (2) three-dimensional aerofoils (induced velocity, aerofoils of finite aspect ratio, the lifting line theory, lifting surface theory, propellers, and wind tunnel corrections); (3) subsonic and supersonic flow (subsonic flow, supersonic flow, supersonic sweptback and delta wings); and, (4) the aircraft as a whole (simple flight problems, moments, and stability). The treatment is founded on complex variable and vector methods, both of which are explained in the self-contained text. A wealth of problems, illustrations, and cross-references add to the book's value both as a text and a reference. The only prerequisite is a knowledge of the elements of the differential and integral calculus.
