With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    You'll learn how to overcome the unique issues that confront nighttime photographers and capture images of which you'll be proud. Co-author Jennifer Wu, an elite Canon "Explorer of Light" professional photographer, has become renowned for her ability to capture nighttime phenomena, from quarter-phase moon rises to shooting stars to the ephemeral Milky Way. this new guide reveals her methods and concentrates on photographing four principal subjects: stars as points of light, star trails, the moon, and twilight. these subjects share common photo techniques and considerations, but each also requires a distinct approach. Once captured, your digital images must be fi nished on the computer; coauthor and author of the bestselling Photography: Outdoors, James Martin, delves into the settings and procedures that elevate an image from mundane to striking. This clear and practical guide will help photographers of all levels portray the stunning spectacle of the night sky, preserving those special memories and moments from a life outdoors.

    Less than 20 years after its founding, it boasts the largest constellation of commercial satellites in orbit, has pioneered reusable rockets, and in 2020 became the first private company to launch human beings into orbit. Half a century after the space race it is private companies, led by SpaceX, standing alongside NASA pushing forward into the cosmos, and laying the foundation for our exploration of other worlds.But before it became one of the most powerful players in the aerospace industry, SpaceX was a fledgling startup, scrambling to develop a single workable rocket before the money ran dry. The engineering challenge was immense; numerous other private companies had failed similar attempts. And even if SpaceX succeeded, they would then have to compete for government contracts with titans such as Lockheed Martin and Boeing, who had tens of thousands of employees and tens of billions of dollars in annual revenue. SpaceX had fewer than 200 employees and the relative pittance of $100 million in the bank.In Liftoff, Eric Berger, senior space editor at Ars Technica, takes readers inside the wild early days that made SpaceX. Focusing on the company’s first four launches of the Falcon 1 rocket, he charts the bumpy journey from scrappy underdog to aerospace pioneer. We travel from company headquarters in El Segundo, to the isolated Texas ranchland where they performed engine tests, to Kwajalein, the tiny atoll in the Pacific where SpaceX launched the Falcon 1. Berger has reported on SpaceX for more than a decade, enjoying unparalleled journalistic access to the company’s inner workings. Liftoff is the culmination of these efforts, drawing upon exclusive interviews with dozens of former and current engineers, designers, mechanics, and executives, including Elon Musk. The enigmatic Musk, who founded the company with the dream of one day settling Mars, is the fuel that propels the book, with his daring vision for the future of space.Filled with never-before-told stories of SpaceX’s turbulent beginning, Liftoff is a saga of cosmic proportions.

    Beginning at Stonehenge and ending with the current crisis in String Theory, the story of this eternal question to uncover the mysteries of the universe describes a narrative that includes some of the greatest discoveries of all time and leading personalities, including Aristotle, Copernicus, and Isaac Newton, and the rise to the modern era of Einstein, Eddington, and Hawking.

    Is this happenstance, providence, or coincidence? According to cosmologist Martin Rees, the answer depends on the answer to another question, the one posed by Einstein's famous remark: ''What interests me most is whether God could have made the world differently.'' This highly engaging book explores the fascinating consequences of the answer being ''yes.'' Rees explores the notion that our universe is just a part of a vast ''multiverse, '' or ensemble of universes, in which most of the other universes are lifeless. What we call the laws of nature would then be no more than local bylaws, imposed in the aftermath of our own Big Bang. In this scenario, our cosmic habitat would be a special, possibly unique universe where the prevailing laws of physics allowed life to emerge.Rees begins by exploring the nature of our solar system and examining a range of related issues such as whether our universe is or isn't infinite. He asks, for example: How likely is life? How credible is the Big Bang theory? Rees then peers into the long-range cosmic future before tracing the causal chain backward to the beginning. He concludes by trying to untangle the paradoxical notion that our entire universe, stretching 10 billion light-years in all directions, emerged from an infinitesimal speck.As Rees argues, we may already have intimations of other universes. But the fate of the multiverse concept depends on the still-unknown bedrock nature of space and time on scales a trillion trillion times smaller than atoms, in the realm governed by the quantum physics of gravity. Expanding our comprehension of the cosmos, Our Cosmic Habitat will be read and enjoyed by all those--scientists and nonscientists alike--who are as fascinated by the universe we inhabit as is the author himself.

    The calls to ban it were more or less instant.Re:cyclists is the tale of what happened next, of how we have spent two centuries wheeling our way about town and country on bikes--or on two-wheeled things that vaguely resembled what we now call bikes. Michael Hutchinson picks his way through those 200 years, discovering how cycling became a kinky vaudeville act for Parisians, how it became an American business empire, and how it went on to find a unique home in the British Isles. He considers the penny-farthing riders exploring the abandoned and lonely coaching roads during the railway era, and the Victorian high-society cyclists of the 1890s bicycle craze--a time when no aristocratic house party was without bicycles and when the Prince of Wales used to give himself an illicit thrill on a weekday afternoon by watching the women's riding-school in the Royal Albert Hall.Re:cyclists looks at how cycling became the sport, the pastime and the social life of millions of ordinary people, how it grew and how it suffered through the 1960s and '70s, and how at the dawn of the twenty-first century it rose again, much changed but still ultimately just someone careering along on two wheels.

    This book, which greatly expands the companion PBS series, tell the stories of the visionaries--based on eyewitness accounts and newly discovered archival material--who helped America win the space race with the first lunar landing fifty years ago. In 1961, President John F. Kennedy proposed the nation spend twenty billion dollars to land a man on the Moon before the end of the decade. For the first time, Chasing the Moon reveals the unknown stories of the fascinating individuals whose imaginative work across several decades culminated in America's momentous achievement. More than a story of engineers and astronauts, the Moon landing--now celebrating its 50th anniversary--grew out of the dreams of science fiction writers, filmmakers, military geniuses and rule-breaking scientists. Going in depth to explore their stories beyond the PBS series, writer/producer Robert Stone--called "one of our most important documentary film makers" by Entertainment Weekly--brings these important figures to brilliant life. They include: * Science fiction author Arthur C. Clarke, whose writing inspired some of the key players in the Moon race. A scientific paper he wrote in his twenties led to the U.S. beating Russia in one area of space: communications satellites.* Wernher von Braun, the Nazi military genius who oversaw Hitler's rocket weapons program. After working on ballistic missiles for the U.S. Army, he was recruited by NASA to manage the creation of the Saturn V Moon rocket. * Astronaut Frank Borman, commander of the first mission to circumnavigate the Moon, whose powerful testimony before Congress in 1967 decisively saved the U.S. lunar program from being cancelled. * Poppy Northcutt, a young mathematician who was the first woman to work in Mission Control. Her media exposure as a unique presence in this all-male world allowed her to stand up for equal rights for women and minorities.* Ed Dwight, an African-American astronaut candidate, recruited at the urging of the Kennedy White House to further the administration's civil rights agenda. But not everyone welcomed his inclusion.Setting these key players in the political, social, and cultural climate of the time, and including captivating photos throughout, Chasing the Moon focuses on the science and the history, but most importantly, the extraordinary individuals behind what was undoubtedly the greatest human achievement of the twentieth century.

    She was in the first class of women to earn pilot’s wings at Vance Air Force Base and was their first female instructor pilot. She was only the second woman admitted to the Air Force’s elite Test Pilot Program at Edwards Air Force Base. NASA had such confidence in her skills as a leader and pilot that she was entrusted to command the first shuttle mission after the Columbia disaster, returning the US to spaceflight after a two-year hiatus. Since retiring from the Air Force and NASA, she has served on numerous corporate boards and is an inspirational speaker about space exploration and leadership.Eileen Collins is among the most recognized and admired women in the world, yet this is the first time she has told her story in a book. It is a story not only of achievement and overcoming obstacles but of profound personal transformation. The shy, quiet child of an alcoholic father and struggling single mother, who grew up in modest circumstances and was an unremarkable student, she had few prospects when she graduated from high school, but she changed her life to pursue her secret dream of becoming an astronaut. She shares her leadership and life lessons throughout the book with the aim of inspiring and passing on her legacy to a new generation.

    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.

    . . Patterson's book must now be considered the definitive Tsavo lion study... one of the world's leading experts on lions as well as an important conservationist.--Publishers WeeklyThrough field research and forensic evidence, a scientist reveals his theory on why two Kenyan lions killed humans and then ate their preyIn March 1898, the British began building a bridge over the Tsavo River in East Africa. In nine months, two male lions killed and ate nearly 135 workers, halting construction.After a long hunt Colonel J. H. Patterson killed the lions, which are now on display at the Field Museum of Natural History in Chicago.As codirector of the Tsavo Research Project, Bruce Patterson has conducted extensive fieldwork throughout the region on these lions. In The Lions of Tsavo, Patterson retells the harrowing story of those bloody nights in Kenya. He presents new forensic evidence on these maneless lions and argues that the man-eating behavior exhibited in 1898 came from the encroachment of human populations on wild habitats.Patterson continues this theory by exploring man's interaction with the changing Kenyan environment, creating a complete, up-to-date, and scientific look behind this intriguing murder mystery.

    It was a thrilling era of open cockpits, silk scarves, leather helmets, and goggles. After serving in World War II, Sutter joined Boeing, then a small company, eager to build airplanes.In July 1965, he was asked to lead the large Boeing team designing the new 747. Pan Am wanted a new airliner as quickly as possible. This all-new transport had to be far bigger than anything in service or even on anybody's drawing board. To make it fly, Sutter and his team would have to push far beyond the technological boundaries of the late 1960s. Could it be done?Almost everything about the 747 would be unprecedented. Its cabin would be so wide that it would need two aisles. Its horizontal tail would be bigger than the wings of most airliners ever built. Jet engines big enough to lift it off the ground didn't yet exist. Runways at the world's airports couldn't handle it, and neither could Boeing's factories. They had to erect the world's largest building just to produce it. A truly mammoth undertaking, the 747 became one of the most successful airplane models ever.Sutter's vivid narrative takes us back to a time when American technology was cutting-edge -- the 747 came on the market the same year that men first set foot on the moon -- and jet travel was still glamorous and new. With wit and warmth, he gives an insider's sense of the larger-than-life-size personalities -- and the tensions -- in the aeronautical world. Ultimately, 747 is an inspiring story of grit and glory.

    Forget this planet. The economy is terrible, global warming is inevitable, and there are at least eight major wars happening right now. That's why Kessler left home and moved to Mars. Well, not all the way to Mars. The closest spot on Earth you can get without a rocket. In the summer of 2008, he lived his space dream, s[ending the months in mission control of The Phoenix expedition with 130 top scientists and engineers as they explored Mars. This story is a human drama about modern-day Magellans battling NASA politics, temperamental robots, and the bizarre world of daily life in mission control. Kessler was the first outsider ever granted unfettered access to such an event, giving us a true Mission-to-Mars exclusive.The Phoenix Mars mission was the first man-made probe ever sent to the Martian arctic. They wanted to find out how climate change can turn a warm, wet planet (read: Earth) into a cold, barren desert (read: Mars). That might seem like a trivial pursuit, but it's probably the most impressive feat we humans can achiee, and it took the culmination of nearly the entirety of human knowledge to do it.Along the way, Phoenix discovered a giant frozen ocean trapped beneath the north pole of Mars, exotic food for aliens and liquid water. This is not science fiction. It's fact. Not bad for a summer holiday.

    The book analyzes how differences could affect the plant, animal and human life on planet Earth.

    Planetary science has mainly been a descriptive science, but it is becoming increasingly experimental. The space probes that went up between the 1960s and 1990s were primarily generalists-they collected massive amounts of information so that scientists could learn what questions to pursue. But recent missions have become more focused: Scientists know better what information they want and how to collect it. Even now probes are on their way to Mercury, Venus, Mars, and Pluto, with Europa-one of Jupiter's moons-on the agenda. In a sweeping look into the manifold objects inhabiting the depths of space, Lives of the Planets delves into the mythology and the knowledge humanity has built over the ages. Placing our current understanding in historical context, Richard Corfield explores the seismic shifts in planetary astronomy and probes why we must change our perspective of our place in the universe. In our era of extraordinary discovery, this is the first comprehensive survey of this new understanding and the history of how we got here.
