Wilson Literary Science Writing Award Harvard's top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star. "Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected."--Alan Lightman, New York Times bestselling author of Einstein's Dreams and Searching for Stars on an Island in Maine In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard's top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization. In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars--and to think critically about what's out there, no matter how strange it seems.

"The world's leading alien hunter" -- New York Times Magazine From acclaimed Harvard astrophysicist and bestselling author of Extraterrestrial comes a mind-expanding new book explaining why becoming an interstellar species is imperative for humanity's survival and detailing a game plan for how we can settle among the stars. In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard's Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth. But a crucial question remained: now that we are aware of the existence of extraterrestrial life, what do we do next? How do we prepare ourselves for interaction with interstellar extraterrestrial civilization? How can our species become interstellar? Now Loeb tackles these questions in a revelatory, powerful call to arms that reimagines the idea of contact with extraterrestrial civilizations. Dismantling our science-fiction fueled visions of a human and alien life encounter, Interstellar provides a realistic and practical blueprint for how such an interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. From awe-inspiring searches for extraterrestrial technology, to the heated debate of the existence of Unidentified Aerial Phenomena, Loeb provides a thrilling, front-row view of the monumental progress in science and technology currently preparing us for contact. He also lays out the profound implications of becoming--or not becoming--interstellar; in an urgent, eloquent appeal for more proactive engagement with the world beyond ours, he powerfully contends why we must seek out other life forms, and in the process, choose who and what we are within the universe. Combining cutting edge science, physics, and philosophy, Interstellar revolutionizes the approach to our search for extraterrestrial life and our preparation for its discovery. In this eye-opening, necessary look at our future, Avi Loeb artfully and expertly raises some of the most important questions facing us as humans, and proves, once again, that scientific curiosity is the key to our survival.

The untold story of the historic voyage to the moon that closed out one of our darkest years with a nearly unimaginable triumph In August 1968, NASA made a bold decision: in just sixteen weeks, the United States would launch humankind's first flight to the moon. Only the year before, three astronauts had burned to death in their spacecraft, and since then the Apollo program had suffered one setback after another. Meanwhile, the Russians were winning the space race, the Cold War was getting hotter by the month, and President Kennedy's promise to put a man on the moon by the end of the decade seemed sure to be broken. But when Frank Borman, Jim Lovell and Bill Anders were summoned to a secret meeting and told of the dangerous mission, they instantly signed on. Written with all the color and verve of the best narrative non-fiction, Apollo 8 takes us from Mission Control to the astronaut's homes, from the test labs to the launch pad. The race to prepare an untested rocket for an unprecedented journey paves the way for the hair-raising trip to the moon. Then, on Christmas Eve, a nation that has suffered a horrendous year of assassinations and war is heartened by an inspiring message from the trio of astronauts in lunar orbit. And when the mission is over--after the first view of the far side of the moon, the first earth-rise, and the first re-entry through the earth's atmosphere following a flight to deep space--the impossible dream of walking on the moon suddenly seems within reach. The full story of Apollo 8 has never been told, and only Jeffrey Kluger--Jim Lovell's co-author on their bestselling book about Apollo 13--can do it justice. Here is the tale of a mission that was both a calculated risk and a wild crapshoot, a stirring account of how three American heroes forever changed our view of the home planet.

Unabridged declassified value reproduction of The Los Alamos Primer by Robert Serber, in full color with all censor markings. This is the booklet given to new workers at Los Alamos during World War II, to catch them up on how to build a practical fission bomb. The Primer was driven by Robert Oppenheimer asking his protégé Robert Serber to summarize all knowledge and possible solutions known as of April 1943 in a series of lectures. Serber did such an excellent job that the notes from the series was turned into The Los Alamos Primer. Serber was known as an expert that bridged theory and reality, and so was also chosen to be one of the first Americans to enter Hiroshima and Nagasaki to assess the atomic damage in 1945.

Over the past few decades there has been a revolution in terms of who controls knowledge and information. This rapid change has imperilled the way we think. Without pausing to consider the cost, the world has rushed to embrace the products and services of four titanic corporations. We shop with Amazon; socialise on Facebook; turn to Apple for entertainment; and rely on Google for information. These firms sell their efficiency and purport to make the world a better place, but what they have done instead is to enable an intoxicating level of daily convenience. As these companies have expanded, marketing themselves as champions of individuality and pluralism, their algorithms have pressed us into conformity and laid waste to privacy. They have produced an unstable and narrow culture of misinformation, and put us on a path to a world without private contemplation, autonomous thought, or solitary introspection - a world without mind. In order to restore our inner lives, we must avoid being co-opted by these gigantic companies, and understand the ideas that underpin their success. Elegantly tracing the intellectual history of computer science - from the Descartes and the enlightenment to Alan Turing to Stuart Brand and the hippie origins of today's Silicon Valley - Foer exposes the dark underpinnings of our most idealistic dreams for technology. The corporate ambitions of Google, Facebook, Apple, and Amazon, he argues, are trampling longstanding liberal values, especially intellectual property and privacy. This is a nascent stage in the total automation and homogenization of social, political, and intellectual life. By reclaiming our private authority over how we intellectually engage with the world, we have the power to stem the tide. At stake is nothing less than who we are, and what we will become. There have been monopolists in the past but today's corporate giants have far more nefarious aims. They're monopolists who want access to every facet of our identities and influence over every corner of our decision-making. Until now few have grasped the sheer scale of the threat. Foer explains not just the looming existential crisis but the imperative of resistance.

We are born with the instinct to create and invent. Indeed our ability to do so is what separates we humans from the rest of the animal world. The moment man first converted a stone to a useful tool set him on a relentless path toward greater control and power over his environment. But have our creative ideas always produced desirable results in line with their original good intention? How many ill-effects and dangers have they brought about along the way? And have they really served us well? Bad Ideas? traces the fascinating history of our attempts at self-improvement but also questions their value. The dubious consequences of the development of weaponry, for example, is self-evident from the primitive but lethal sling to the devastating nuclear bomb. But what of apparently more innocuous inventions such as farming, writing or medicine? All were initiated for the greater good but have nonetheless produced unforeseen fallout that continues to this day. What are their undesirable side-effects, how did they emerge over the years and where will they take us in the future? Written against a huge historical canvas, we join Robert Winston on a thrilling and inspiring journey from our earliest days to the present. We learn about the history of modern science, engineering, IT and much more, following the unexpected twists and turns of their progress. We meet the individuals who played a key role in their development, and share quirky anecdotes about their lives and brainwaves. Inspiring, unusual, and at times controversial, Bad Ideas? enables us by appreciating the past to look forward to the technological opportunities and ethical challenges of the future. In so doing it celebrates man's extraordinary capacity for achievement whilst warning us that his good intentions can sometimes end up as thoroughly bad ideas.

"Robert Zubrin is a true engineering genius like the heroic engineers of the past." -- Frederick Turner, American Enterprise Using nuts-and-bolts engineering and a unique grasp of human history, Robert Zubrin takes us to the not-very-distant future, when our global society will branch out into the universe. From the current-day prospect of lunar bases and Mars settlements to the outer reaches of other galaxies, Zubrin delivers the most important and forward-looking work on space and the true possibilities of human exploration since Carl Sagan's Cosmos. Sagan himself said of Zubrin's humans-to-Mars plan, " Bob Zubrin really, nearly alone, changed our thinking on this issue." With Entering Space , he takes us further, into the prospect of human expansion to the outer planets of our own solar system--and beyond.

Product Description The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. Review From the book reviews:“This book … edited and written by great scientists covers essential contributions on different types of prokaryotic communities as well as on the prokaryotic functions in different environments. … This volume, as well as the whole series, should be available in every large scientific library.” (Ioan I.

From stem cell research to global warming, human cloning, evolution, and beyond, political debates about science have raged in recent years - and, to the chagrin of most observers, have increasingly fallen into the familiar categories of America's culture wars. In Imagining the Future: Science and American Democracy, Yuval Levin explores the complicated meanings of science and technology in American politics and finds that the science debates have a lot to teach us about our political life. These debates, Levin argues, reveal some serious challenges to American self-government, and put on stark display the deepest strengths and greatest weaknesses of both the left and the right. American life has been profoundly shaped by science and technology, and will be all the more so in the coming decades, making it crucial that we understand how to think and speak about science in politics. Yuval Levin's smart and eminently well-reasoned book makes the important point that the purpose of science is a moral one -- to improve human life -- and that judging what that involves is sometimes a job for more than science alone in a democratic society. Levin's insights speak directly to today's political debates and make his book a must-read for policymakers and all those who care about science and society. --Newt Gingrich, former Speaker of the House Imagining the Future goes far beyond the contemporary polarized debates over science to unpack the moral premises of the modern scientific project and its consequences for American democracy. In the process, Yuval Levin provides us with a deep understanding of policy issues from genetic engineering to global warming. --Francis Fukuyama, Johns Hopkins University This book is important to the thinking of both progressives and conservatives. Clearly and incisively, it shows how science and technology are shaping humanity's future and world views. Levin alerts democratic societies that human dignity and equality are imperiled unless we provide political and moral guidance to prevent the submergence of humanity in its own ingenuity. --Edmund Pellegrino, Chairman, President's Council on Bioethics

In these engaging memoirs of a maverick, Theodore H. Maiman describes the life events leading to his invention of the laser in 1960. Maiman succeeded using his expertise in physics and engineering along with an ingenious and elegant design not anticipated by others. His pink ruby laser produced mankind’s first-ever coherent light and has provided transformational technology for commerce, industry, telecom, the Internet, medicine, and all the sciences. Maiman also chronicles the resistance from his employer and the ongoing intrigue by competing researchers in industry and academia seeking to diminish his contribution in inventing the first laser. This work will appeal to a wide readership, from physicists and engineers through science enthusiasts to general readers. The volume includes extensive photos and documentary materials related to Maiman’s life and accomplishments never before published. "No one beat Maiman to the laser. How important is the laser? How important are all lasers? That is how important we have to regard Maiman’s contribution.He and the laser changed all of our lives, everyone’s!"Dr. Nick Holonyak, Jr., Professor of Electrical and Computer Engineering and Physics, University of Illinois at Champaigne-Urbana, and inventor of the light-emitting diode (LED) and co-inventor of the transistor laser "More than five decades later, we can safely conclude that Theodore Maiman's groundbreaking discovery changed the world. Our modern life just as scientific research would be quite different without the laser."Dr. Ferenc Krausz, Director, Max Planck Institute for Quantum Optics, Garching, Germany, and Professor of Physics, Ludwig Maximilian University, Munich, and pioneer in attosecond lasers and attophysics "Maiman had the stroke of genius needed to take a different approach [from his competitors]. The sheer elegance and simplicity of his design beliesthe intellectual achievement it represents. If his invention seems obvious to some today, it was far from obvious in 1960."Jeff Hecht, authoritative science writer on the historical development of the laser, author of books on lasers and fiber optics

The Omnibook aims to present the main ideas of reactor design in a simple and direct way. it includes key formulas, brief explanations, practice exercises, problems from experience and it skims over the field touching on all sorts of reaction systems. Most important of all it tries to show the reader how to approach the problems of reactor design and what questions to ask. In effect it tries to show that a common strategy threads its way through all reactor problems, a strategy which involves three identifying the flow patter, knowing the kinetics, and developing the proper performance equation. It is this common strategy which is the heart of Chemical Reaction Engineering and identifies it as a distinct field of study.
