Our Mathematical Universe: My Quest for the Ultimate Nature of Reality


Max Tegmark - 2012
    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?

A Short History of Nearly Everything


Bill Bryson - 2003
    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

Dark Money: The Hidden History of the Billionaires Behind the Rise of the Radical Right


Jane Mayer - 2016
    But as Jane Mayer shows in this powerful, meticulously reported history, a network of exceedingly wealthy people with extreme libertarian views bankrolled a systematic, step-by-step plan to fundamentally alter the American political system.The network has brought together some of the richest people on the planet. Their core beliefs—that taxes are a form of tyranny; that government oversight of business is an assault on freedom—are sincerely held. But these beliefs also advance their personal and corporate interests: Many of their companies have run afoul of federal pollution, worker safety, securities, and tax laws.The chief figures in the network are Charles and David Koch, whose father made his fortune in part by building oil refineries in Stalin’s Russia and Hitler’s Germany. The patriarch later was a founding member of the John Birch Society, whose politics were so radical it believed Dwight Eisenhower was a communist. The brothers were schooled in a political philosophy that asserted the only role of government is to provide security and to enforce property rights.When libertarian ideas proved decidedly unpopular with voters, the Koch brothers and their allies chose another path. If they pooled their vast resources, they could fund an interlocking array of organizations that could work in tandem to influence and ultimately control academic institutions, think tanks, the courts, statehouses, Congress, and, they hoped, the presidency. Richard Mellon Scaife, the mercurial heir to banking and oil fortunes, had the brilliant insight that most of their political activities could be written off as tax-deductible “philanthropy.”These organizations were given innocuous names such as Americans for Prosperity. Funding sources were hidden whenever possible. This process reached its apotheosis with the allegedly populist Tea Party movement, abetted mightily by the Citizens United decision—a case conceived of by legal advocates funded by the network.The political operatives the network employs are disciplined, smart, and at times ruthless. Mayer documents instances in which people affiliated with these groups hired private detectives to impugn whistle-blowers, journalists, and even government investigators. And their efforts have been remarkably successful. Libertarian views on taxes and regulation, once far outside the mainstream and still rejected by most Americans, are ascendant in the majority of state governments, the Supreme Court, and Congress. Meaningful environmental, labor, finance, and tax reforms have been stymied.Jane Mayer spent five years conducting hundreds of interviews-including with several sources within the network-and scoured public records, private papers, and court proceedings in reporting this book. In a taut and utterly convincing narrative, she traces the byzantine trail of the billions of dollars spent by the network and provides vivid portraits of the colorful figures behind the new American oligarchy.Dark Money is a book that must be read by anyone who cares about the future of American democracy.

Seven Brief Lessons on Physics


Carlo Rovelli - 2014
    A playful, entertaining, and mind-bending introduction to modern physics, it's already a major bestseller in Italy and the United Kingdom. Carlo Rovelli offers surprising—and surprisingly easy to grasp—explanations of general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the universe, and the role humans play in this weird and wonderful world. He takes us to the frontiers of our knowledge: to the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds. “Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world,” Rovelli writes. “And it’s breathtaking.”

Comm Check...: The Final Flight of Shuttle Columbia


Michael Cabbage - 2004
    The space shuttle Columbia disintegrated 37 miles above Texas, seven brave astronauts were killed and America's space program, always an eyeblink from disaster, suffered its second catastrophic in-flight failure. Unlike the Challenger disaster 17 years earlier, Columbia's destruction left the nation one failure away from the potential abandonment of human space exploration. Media coverage in the immediate aftermath focused on the possible cause of the disaster, and on the nation's grief. But the full human story, and the shocking details of NASA's crucial mistakes, have never been told -- until now.Based on dozens of exclusive interviews, never-before-published documents and recordings of key meetings obtained by the authors, "Comm Check" takes the reader inside the conference rooms and offices where NASA's best and brightest managed the nation's multi-billion-dollar shuttle program -- and where they failed to recognize the signs of an impending disaster. It is the story of a space program pushed to the brink of failure by relentless political pressure, shrinking budgets and flawed decision making. The independent investigation into the disaster uncovered why Columbia broke apart in the sky above Texas. "Comm Check" brings that story to life with the human drama behind the tragedy.Michael Cabbage and William Harwood, two of America's most respected space journalists, are veterans of all but a handful of NASA's 113 shuttle missions. Tapping a network of sources and bringing a combined three decades of experience to bear, the authors provide a rare glimpse into NASA's inner circles, chronicling the agency's most devastating failure andthe challenges that face NASA as it struggles to return America to space.

Boyd: The Fighter Pilot Who Changed the Art of War


Robert Coram - 2002
    Some remember him as the greatest U.S. fighter pilot ever -- the man who, in simulated air-to-air combat, defeated every challenger in less than forty seconds. Some recall him as the father of our country's most legendary fighter aircraft -- the F-15 and F-16. Still others think of Boyd as the most influential military theorist since Sun Tzu. They know only half the story. Boyd, more than any other person, saved fighter aviation from the predations of the Strategic Air Command. His manual of fighter tactics changed the way every air force in the world flies and fights. He discovered a physical theory that forever altered the way fighter planes were designed. Later in life, he developed a theory of military strategy that has been adopted throughout the world and even applied to business models for maximizing efficiency. And in one of the most startling and unknown stories of modern military history, the Air Force fighter pilot taught the U.S. Marine Corps how to fight war on the ground. His ideas led to America's swift and decisive victory in the Gulf War and foretold the terrorist attacks of September 11, 2001. On a personal level, Boyd rarely met a general he couldn't offend. He was loud, abrasive, and profane. A man of daring, ferocious passion and intractable stubbornness, he was that most American of heroes -- a rebel who cared not for his reputation or fortune but for his country. He was a true patriot, a man who made a career of challenging the shortsighted and self-serving Pentagon bureaucracy. America owes Boyd and his disciples -- the six men known as the "Acolytes" -- a great debt. Robert Coram finally brings to light the remarkable story of a man who polarized all who knew him, but who left a legacy that will influence the military -- and all of America -- for decades to come . . .

How I Killed Pluto and Why It Had It Coming


Mike Brown - 2010
    Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye. The debate culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about.Filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is Mike Brown’s engaging first-person account of the most tumultuous year in modern astronomy—which he inadvertently caused. As it guides readers through important scientific concepts and inspires us to think more deeply about our place in the cosmos, it is also an entertaining and enlightening personal story: While Brown sought to expand our understanding of the vast nature of space, his own life was changed in the most immediate, human ways by love, birth, and death. A heartfelt and personal perspective on the demotion of everyone’s favorite farflung planet, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever dreamed of exploring the universe—and who among us hasn’t?

The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality


Richard Panek - 2010
      In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

We Are All Stardust: Leading Scientists Talk About Their Work, Their Lives, and the Mysteries of Our Existence


Stefan KleinWalter Ziegänsberger - 2010
    How does Jane Goodall’s relationship with her dog Rusty inform her thinking about our relationship to other species? Which time and place would Jared Diamond most prefer to live in, in light of his work on the role of chance in history? What does driving a sports car have to do with Steven Weinberg’s quest for the “theory of everything”? Physicist and journalist Stefan Klein’s intimate conversations with nineteen of the world’s best-known scientists (including three Nobel Laureates) let us listen in as they talk about their paradigm-changing work—and how it is deeply rooted in their daily lives. • Cosmologist Martin Rees on the beginning and end of the world • Evolutionary biologist Richard Dawkins on egoism and selflessness • Neuroscientist V. S. Ramachandran on consciousness • Molecular biologist Elizabeth Blackburn on aging • Philosopher Peter Singer on morality • Physician and social scientist Nicholas Christakis on human relationships • Biochemist Craig Venter on the human genome • Chemist and poet Roald Hoffmann on beauty

Ignition!: An informal history of liquid rocket propellants


John Drury Clark - 1972
    A favorite of Tesla and SpaceX founder Elon Musk, listeners will want to tune into this "really good book on rocket[s]," available for the first time in audio. Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, listeners will want to get their hands on this influential classic, available for the first time in decades.

The Rise and Fall of the Dinosaurs: A New History of a Lost World


Stephen Brusatte - 2018
    Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before.In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages.Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.”Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China.An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come.

To Explain the World: The Discovery of Modern Science


Steven Weinberg - 2015
    He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world—they did not understand what there is to understand, or how to understand it. Yet over the centuries, through the struggle to solve such mysteries as the curious backward movement of the planets and the rise and fall of the tides, the modern discipline of science eventually emerged. Along the way, Weinberg examines historic clashes and collaborations between science and the competing spheres of religion, technology, poetry, mathematics, and philosophy.An illuminating exploration of the way we consider and analyze the world around us, To Explain the World is a sweeping, ambitious account of how difficult it was to discover the goals and methods of modern science, and the impact of this discovery on human knowledge and development.

Moon Lander: How We Developed the Apollo Lunar Module


Thomas J. Kelly - 2001
    Kelly gives a firsthand account of designing, building, testing, and flying the Apollo lunar module. It was, he writes, "an aerospace engineer's dream job of the century." Kelly's account begins with the imaginative process of sketching solutions to a host of technical challenges with an emphasis on safety, reliability, and maintainability. He catalogs numerous test failures, including propulsion-system leaks, ascent-engine instability, stress corrosion of the aluminum alloy parts, and battery problems, as well as their fixes under the ever-present constraints of budget and schedule. He also recaptures the exhilaration of hearing Apollo 11's Neil Armstrong report that "The Eagle has landed," and the pride of having inadvertently provided a vital "lifeboat" for the crew of the disabled Apollo 13.

Leap of Faith: An Astronaut's Journey Into the Unknown


L. Gordon Cooper Jr. - 2000
    Today he's a part of our nation's history as one of the surviving Mercury space pioneers. Leap of Faith not only reveals what went on behind the scenes of the early space program, but also takes aim at the next millennium of space travel with strong views on the existence of extraterrestrial intelligence--& even the distinct possibility we've already had contact. During his military career, he was one of the best of the best at Edwards Air Force Base, where the setting of world records for speed, endurance & altitude was an everyday occurrence. Even before joining the newly formed manned space program, he understood the dangerous nature of new technologies: hanging it over the edge & pushing the envelope, then hauling it back in & doing it again tomorrow. Gordo Cooper learned to fly with his father at age 8 in his hometown of Shawnee, OK, soloing by age 12. As an impressionable boy, he met overnight visitors to the household, including famous aviators like Amelia Earhart & Wiley Post, heightening his desire to take to the skies. Ride with Cooper thru his adventurous life in the cockpits of planes & spacecraft alike. He was the last American to go into space alone. He flew in Mercury & Gemini, & served as head of flight crew operations for both Apollo & Skylab, America's 1st orbiting space station. He was backup command pilot for Apollo X & directed design input changes for the shuttle program. He was buddies with Gus Grissom, who died in the Apollo I fire at Cape Canaveral, & was close to Wernher von Braun, the German rocket scientist who was responsible for the USA beating Russia to the Moon. Thru it all, Cooper, a hero who shuns the label, speaks candidly of his defeats as well as his accomplishments. His life is a tapestry of space travel in the 20th century. From a source as credible as Cooper come these claims: He innocently took revealing pictures of the mysterious Area 51 during his Gemini mission & ended up in the White House speaking about it to the president; he & other military jet pilots have chased UFOs; & footage of UFOs taken by his film crew was confiscated by the government, all part of the military's long-time UFO cover-up.
