At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges--Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates.The "glass universe" of half a million plates that Harvard amassed over the ensuing decades--through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography--enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard--and Harvard's first female department chair.

    Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

    That judgment, implausible even to a casual fan, also contradicted the opinion of a growing cadre of neuroscientists who worked in vain to convince the NFL that it was facing a deadly new scourge: A chronic brain disease that was driving an alarming number of players -- including some of the all-time greats -- to madness.League of Denial reveals how the NFL, over a period of nearly two decades, sought to cover up and deny mounting evidence of the connection between football and brain damage.Comprehensively, and for the first time, award-winning ESPN investigative reporters Mark Fainaru-Wada and Steve Fainaru tell the story of a public health crisis that emerged from the playing fields of our 21st century pastime. Everyone knew that football is violent and dangerous. But what the players who built the NFL into a $10 billion industry didn’t know – and what the league sought to shield from them – is that no amount of padding could protect the human brain from the force generated by modern football; that the very essence of the game could be exposing these players to brain damage.In a fast-paced narrative that moves between the NFL trenches, America’s research labs and the boardrooms where the NFL went to war against science, League of Denial examines how the league used its power and resources to attack independent scientists and elevate its own flawed research -- a campaign with echoes of Big Tobacco’s fight to deny the connection between smoking and lung cancer. It chronicles the tragic fates of players like Hall of Fame Pittsburgh Steelers center Mike Webster, who was so disturbed at the time of his death he fantasized about shooting NFL executives; and former Chargers great Junior Seau, whose diseased brain became the target of an unseemly scientific battle between researchers and the NFL. Based on exclusive interviews, previously undisclosed documents and private emails, this is the story of what the NFL knew and when it knew it – questions at the heart of crisis that threatens football, from the highest levels all the way down to Pop Warner.

    The general said it was. This set in motion the first presidential directive on computer security.The first use of cyber techniques in battle occurred in George H.W. Bush's Kuwait invasion in 1991 to disable Saddam's military communications. One year later, the NSA Director watched Sneakers, in which one of the characters says wars will soon be decided not by bullets or bombs but by information. The NSA and the Pentagon have been rowing over control of cyber weapons ever since.From the 1994 (aborted) US invasion of Haiti, when the plan was to neutralize Haitian air-defenses by making all the telephones in Haiti busy at the same time, to Obama's Defense Department 2015 report on cyber policy that spells out the lead role played by our offensive operation, Fred Kaplan tells the story of the NSA and the Pentagon as they explore, exploit, fight, and defend the US. Dark Territory reveals all the details, including the 1998 incident when someone hacked into major US military commands and it wasn't Iraq, but two teenagers from California; how Israeli jets bomb a nuclear reactor in Syria in 2007 by hacking into Syrian air-defense radar system; the time in 2014 when North Korea hacks Sony's networks to pressure the studio to cancel a major Hollywood blockbuster; and many more. Dark Territory is the most urgent and controversial topic in national defense policy.

    From dramatic, high-risk spacewalks to author Scott Parazynski’s death-defying quest to summit Mount Everest—his body ravaged by a career in space—readers will experience the life of an elite athlete, physician, and explorer.This intimate, compelling account offers a rare portrait of space exploration from the inside. A global nomad raised in the shadow of NASA’s Apollo missions, Parazynski never lost sight of his childhood dream to one day don a spacesuit and float outside the airlock. With deep passion, unbridled creativity, resilience, humility, and self-deprecation, Parazynski chases his dream of the ultimate adventure experience, again and again and again. In an era that transitioned from moon shots to the Space Shuttle, space station, and Mars research, Parazynski flies with John Glenn, tests jet packs, trains in Russia to become a cosmonaut, and flies five missions to outer space (including seven spacewalks) in his seventeen-year NASA career.An unparalleled, visceral opportunity to understand what it’s like to train for—and deploy to—a home in zero gravity, The Sky Below also portrays an astronaut’s engagement with the challenges of his life on Earth, including raising a beautiful autistic daughter and finding true love.

    Then, in 1961, John F. Kennedy challenged America -- and from Long Island to Cape Canaveral, Houston to Huntsville, an army of engineers, scientists, bureaucrats and astronauts were swept up into the effort. Somehow, America would put a man on the moon's surface and bring him back safely before the decade was over. But how?For eight frantic years the engineers would design and redesign, the scientists would argue, and brave men would trust their lives to virtually untested machinery. This dramatic chronicle of the race to the moon takes us behind the scenes of this awesome quest, into the minds of the people whose lives were devoted to it and changed by it, and through the missions themselves -- including the tragedy of Apollo 13. A riveting portrait of ingenuity, determination, and raw human courage, "Chariots for Apollo is the powerful story of how one society came together to reach its goal -- a quarter of a million miles away.

    It’s not just that the grid has grown old and is now in dire need of basic repair. Today, as we invest great hope in new energy sources--solar, wind, and other alternatives--the grid is what stands most firmly in the way of a brighter energy future. If we hope to realize this future, we need to re-imagine the grid according to twenty-first-century values. It’s a project which forces visionaries to work with bureaucrats, legislators with storm-flattened communities, moneymen with hippies, and the left with the right. And though it might not yet be obvious, this revolution is already well under way.Cultural anthropologist Gretchen Bakke unveils the many facets of America's energy infrastructure, its most dynamic moments and its most stable ones, and its essential role in personal and national life. The grid, she argues, is an essentially American artifact, one which developed with us: a product of bold expansion, the occasional foolhardy vision, some genius technologies, and constant improvisation. Most of all, her focus is on how Americans are changing the grid right now, sometimes with gumption and big dreams and sometimes with legislation or the brandishing of guns.The Grid tells--entertainingly, perceptively--the story of what has been called “the largest machine in the world”: its fascinating history, its problematic present, and its potential role in a brighter, cleaner future.

    Yuri Gagarin is one of the great heroes of the twentieth century, but the details of his life and the Russian space effort have been shrouded in secrecy: even the names of the engineers who worked with Gagarin were a mystery to the West for many years.Starman is the first book to tell the compelling story behind Gagarin's life and his audacious first flight into space aboard a converted nuclear weapon.He was once the most famous man in the world yet in his life, as in death, he was a man the world knew almost nothing about.

    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.

    Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

    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.

    But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life.In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together.Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

    But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list.  Maxwell, an unassuming Victorian Scotsman, explained how we perceive colour. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.   Along the way, he set up one of the most enduring challenges in physics, one that has taxed the best minds ever since. ‘Maxwell’s demon’ is a tiny but thoroughly disruptive thought experiment that suggests the second law of thermodynamics, the law that governs the flow of time itself, can be broken. This is the story of a groundbreaking scientist, a great contributor to our understanding of the way the world works, and his duplicitous demon.

    Light years ahead of anything previously put into space, and built on technology developed for Ronald Reagan’s “Star Wars,” Iridium’s constellation of 66 satellites in polar orbit meant that no matter where you were on Earth, at least one satellite was always overhead, and you could call Tibet from Fiji without a delay and without your call ever touching a wire.Iridium the satellite system was a mind-boggling technical accomplishment, surely the future of communication. The only problem was that Iridium the company was a commercial disaster. Only months after launching service, it was $11 billion in debt, burning through $100 million a month and crippled by baroque rate plans and agreements that forced calls through Moscow, Beijing, Fucino, Italy, and elsewhere. Bankruptcy was inevitable—the largest to that point in American history. And when no real buyers seemed to materialize, it looked like Iridium would go down as just a “science experiment.”That is, until Dan Colussy got a wild idea. Colussy, a former head of Pan-Am now retired and working on his golf game in Palm Beach, heard about Motorola’s plans to “de-orbit” the system and decided he would buy Iridium and somehow turn around one of the biggest blunders in the history of business.In Eccentric Orbits, John Bloom masterfully traces the conception, development, and launching of Iridium and Colussy’s tireless efforts to stop it from being destroyed, from meetings with his motley investor group, to the Clinton White House, to the Pentagon, to the hunt for customers in special ops, shipping, aviation, mining, search and rescue—anyone who would need a durable phone at the end of the Earth. Impeccably researched and wonderfully told, Eccentric Orbits is a rollicking, unforgettable tale of technological achievement, business failure, the military-industrial complex, and one of the greatest deals of all time.

    Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out.Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds.Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.
