The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it.  The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of approaching and grappling with some of the universe's most pressing and vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered? What are some of the next avenues of exploration for today's chemists, physicists, biologists, and astronomers? Pondering the answers to these and other questions is a great way to appreciate the grandeur and complexity of the world around you, better understand and discuss news and developments in science, and spark further interest in some of science's many exciting areas of study. "We know a lot about the universe. But there's even more that we don't know,"says astrophysicist and Professor Neil deGrasse Tyson, director of the Hayden Planetarium, an award-winning lecturer, and one of the world's foremost experts on the secrets of the universe. And his course The Inexplicable Universe: Unsolved Mysteries is the perfect gateway into this mind-bending and eye-opening subject. Each of these six self-contained lectures is a marvelous journey to the frontiers of the known (and unknown) universe and introduces you to tantalizing questions being addressed by the world's top scientists. Undeniably engaging and fascinating, this lecture series is a wonderful entrée to scientific pursuits that lie at the very heart of the history and nature of our universe. An Informed Scientific Conversation Central to The Inexplicable Universe is the way it takes you deep into hidden layers of the universe in a manner that is extremely accessible. Rather than a stern lecture given before a podium complete with confusing mathematics, Professor Tyson's lectures have the feel of an informed conversation that manages to be both thorough and easy to grasp. With each of the inexplicable mysteries he lays bare for you, Professor Tyson introduces you to the history behind it, lays out the science that has helped us grasp it, explains what researchers have discovered to date, and reveals what we have yet to discover. And while the topics explore subjects in everything from quantum mechanics to cosmology to string theory, you'll never feel overwhelmed by what you're learning. In fact, you're more likely to find yourself intrigued by just how much we know-and curious about what the near future will possibly reveal. Explore Fascinating Territory So what territory will you chart in this course? Here are some of the inexplicable ideas you'll investigate in these lectures. Neutrinos: Discovered in 1956, these fast-moving, ghostlike particles are made in abundance in the sun's core. They hardly interact with matter; it takes a light-year's worth of lead (5.8 trillion miles) to stop a neutrino. Not only that, but 65 billion neutrinos pass through every centimeter of your body that's facing the sun every second of every day. String theory: This astounding theory offers the hope of unifying all the particles and forces of physics. In the past several decades since the dawn of string theory, it's been imagined that all the fundamental particles we see and measure are just the manifestation in our dimension of strings vibrating in higher dimensions and at different frequencies. Quantum foam: This idea posits that when the fabric of space and time is so tightly curved on itself, space-time is less a smooth curve and more like the froth on a latte. In this state of matter and energy, quantum fluctuations can spawn entire universes, each with slightly different laws of physics within them! In addition, you'll also get a peek at what it would be like to travel through a black hole, ponder the possibility that life on Earth originated in debris from Mars, probe the supposed existence of multiple universes, and even imagine the possible end of the universe itself. A One-on-One Chat with a Renowned Science Educator Professor Tyson is renowned throughout the scientific community and the media for his vast knowledge, his penetrating insights, and his amazing ability to make even the most intimidating areas of science accessible, engaging, and-most of all-enjoyable. He brings the same inviting tone and sharp intellect to The Inexplicable Universe as he does to his range of media appearances on popular television programs. Due to its unique subject matter The Inexplicable Universe takes a highly visual approach. Many of the fascinating subjects in the course, such as black holes, string theory, and multiple universes are best demonstrated visually and Professor Tyson's lectures feature expertly crafted computer animations, explanatory diagrams, high resolution photographs, and other instructive visual elements. In order to better explain to you some of the grand, intricate ideas being discussed, Professor Tyson personally interacts with many of these animations and graphics using greenscreen technology. Please note that, due to the highly visual nature of The Inexplicable Universe, the course does not come with a guidebook. We did not believe a simple book could adequately convey the information in the course, and rather than make a guidebook that did not do the course justice, we decided to not offer one. However, we believe that you will be very excited by how we produced this course and will find it to be an enriching and fulfilling experience in your educational journey.

     Few people know much about stem cell research beyond the ethical questions raised by using embryos. But in the last decade, stem cell research has made huge advances toward eliminating some of our most intractable diseases. Now this sweeping and accessible book introduces us to this cutting-edge science that will revolutionize medicine and change the way we think about and treat disease. Alice Park takes us from stem cell's controversial beginnings to the recent electrifying promise of being able to create the versatile cells without using embryos at all. She shows us how stem cells give researchers an unprecedented ability to study disease while giving patients the promise of replacing diseased cells with healthy new ones. And she profiles the scientists and leaders-many with their own compelling stories-who have fueled the quest and will continue to shape the field in years to come.

    In 1985 Hans von Ohain, the scientist who pioneered Nazi Germany's efforts to build a jet plane, posed the question: 'Would World War II have occured if the Luftwaffe knew it faced operational British jets instead of Spitfires?' He immediately answered, 'I, for one, think not.'Frank Whittle, working-class outsider and self-taught enthusiast, had worked out the blueprint of a completely new type of engine in 1929, only for his ideas to be blocked by bureaucratic opposition until the outbreak of war in 1939. The importance of his work was recognized too late by the government for his revolutionary engine to play a major part in World War II. After the war Whittle's dream of civilian jet-powered aircraft became a reality and Britain enjoyed a golden age of 1950's jet-powered flight.Drawing on Whittle's extensive private papers, Campbell-Smith tells the story of a stoic and overlooked British hero, a tantalizing tale of 'what might have been'.

     The Science Book covers every area of science--astronomy, biology, chemistry, geology, math, and physics, and brings the greatest scientific ideas to life with fascinating text, quirky graphics, and pithy quotes.

    It was a sea in name only. It was actually a bone dry, ancient dusty basin pockmarked with craters and littered with rocks and boulders. Somewhere in that 500 mile diameter basin, the astronauts would attempt to make Mankind’s first landing on the Moon. Neil Armstrong would pilot the Lunar Module “Eagle” during its twelve minute descent from orbit down to a landing. Col. Edwin “Buzz” Aldrin would assist him. On the way down they would encounter a host of problems, any one of which could have potentially caused them to have to call off the landing, or, even worse, die making the attempt. The problems were all technical-communications problems, computer problems, guidance problems, sensor problems. Armstrong and Aldrin faced the very real risk of dying by the very same technical sword that they had to live by in order to accomplish the enormous task of landing on the Moon for the first time. Yet the human skills Armstrong and Aldrin employed would be more than equal to the task. Armstrong’s formidable skills as an aviator, honed from the time he was a young boy, would serve him well as he piloted Eagle down amidst a continuing series of systems problems that might have fatally distracted a lesser aviator. Armstrong’s brilliant piloting was complemented by Aldrin’s equally remarkable discipline and calmness as he stoically provided a running commentary on altitude and descent rate while handling systems problems that threatened the landing. Finally, after a harrowing twelve and a half minutes, Armstrong gently landed Eagle at “Tranquility Base”, a name he had personally chosen to denote the location of the first Moon landing. In “Landing Eagle-Inside the Cockpit During the First Moon Landing”, author Mike Engle gives a minute by minute account of the events that occurred throughout Eagle’s descent and landing on the Moon. Engle, a retired NASA engineer and Mission Control flight controller, uses NASA audio files of actual voice recordings made inside Eagle’s cockpit during landing to give the reader an “inside the cockpit” perspective on the first Moon landing. Engle’s transcripts of these recordings, along with background material on the history and technical details behind the enormous effort to accomplish the first Moon landing, give a new and fascinating insight into the events that occurred on that remarkable day fifty years ago.

    By building a network of computers, he believed the government could avoid buying so many new ones for academic research. From these modest Cold War beginnings a global networking industry has flourished, creating virtual communities, online shopping, the ubiquitous e-mail, and immense fortunes. Stephen Segaller's timely book draws on interviews with more than seventy of the pioneers who have used their technological genius and business skills to make incompatible systems work together, to make networking user-friendly, and to create a new global communications medium that rivals the telephone system or television in its scope and reach.Nerds 2.0.1 tells the dramatic, often comical story of how the world's computers have come to be wired together over the last thirty years. This paperback reprint contains new material to update the picture of this still-evolving saga.

    On March 9, 1945, it created an inferno that killed over 87,500 people in Tokyo--more than died in the atomic explosions at Hiroshima or Nagasaki. It went on to incinerate sixty-four of Japan's largest cities. The Bomb got the press, but napalm did the work.After World War II, the incendiary held the line against communism in Greece and Korea--Napalm Day led the 1950 counter-attack from Inchon--and fought elsewhere under many flags. Americans generally applauded, until the Vietnam War. Today, napalm lives on as a pariah: a symbol of American cruelty and the misguided use of power, according to anti-war protesters in the 1960s and popular culture from "Apocalypse Now" to the punk band Napalm Death and British street artist Banksy. Its use by Serbia in 1994 and by the United States in Iraq in 2003 drew condemnation. United Nations delegates judged deployment against concentrations of civilians a war crime in 1980. After thirty-one years, America joined the global consensus, in 2011.Robert Neer has written the first history of napalm, from its inaugural test on the Harvard College soccer field, to a Marine Corps plan to attack Japan with millions of bats armed with tiny napalm time bombs, to the reflections of Phan Thi Kim Phuc, a girl who knew firsthand about its power and its morality.

    Spanning much of the eighteenth and nineteenth centuries, the novel follows the fortunes of the extraordinary Whittaker family as led by the enterprising Henry Whittaker—a poor-born Englishman who makes a great fortune in the South American quinine trade, eventually becoming the richest man in Philadelphia. Born in 1800, Henry's brilliant daughter, Alma (who inherits both her father's money and his mind), ultimately becomes a botanist of considerable gifts herself. As Alma's research takes her deeper into the mysteries of evolution, she falls in love with a man named Ambrose Pike who makes incomparable paintings of orchids and who draws her in the exact opposite direction — into the realm of the spiritual, the divine, and the magical. Alma is a clear-minded scientist; Ambrose a utopian artist — but what unites this unlikely couple is a desperate need to understand the workings of this world and the mechanisms behind all life.Exquisitely researched and told at a galloping pace, The Signature of All Things soars across the globe—from London to Peru to Philadelphia to Tahiti to Amsterdam, and beyond. Along the way, the story is peopled with unforgettable characters: missionaries, abolitionists, adventurers, astronomers, sea captains, geniuses, and the quite mad. But most memorable of all, it is the story of Alma Whittaker, who — born in the Age of Enlightenment, but living well into the Industrial Revolution — bears witness to that extraordinary moment in human history when all the old assumptions about science, religion, commerce, and class were exploding into dangerous new ideas. Written in the bold, questing spirit of that singular time, Gilbert's wise, deep, and spellbinding tale is certain to capture the hearts and minds of readers.

    But who was Turing, and what did he achieve during his tragically short life of 41 years? Best known as the genius who broke Germany's most secret codes during the war of 1939-45, Turing was also the father of the modern computer. Today, all who 'click-to-open' are familiar with the impact of Turing's ideas.Here, B. Jack Copeland provides an account of Turing's life and work, exploring the key elements of his life-story in tandem with his leading ideas and contributions. The book highlights Turing's contributions to computing and to computer science, including Artificial Intelligence and Artificial Life, and the emphasis throughout is on the relevance of his work to modern developments. The story of his contributions to codebreaking during the Second World War is set in the context of his thinking about machines, as is the account of his work in the foundations of mathematics.

    If today you’ve listened to recorded music, watched a television show or movie, plugged something into an electric socket, had an X-ray, turned on your car, spoke on the telephone, or flicked on an electric light, you have Edison to thank for his pioneering work in these fields, and many more. Yet Edison is all too often remembered in popular culture only as villain for his feuds with other inventors, most notably the mad genius Nikola Tesla. In this thrilling, compact biography, Alexander Kennedy sorts fact from fiction in the life of the most prolific inventor in human history. We follow Edison, the ultimate self-made man, from his origins as a Michigan telegraph boy to the pinnacle of success as an industrial titan. Along the way, Kennedy carefully explains each of Edison’s key breakthroughs as well as the blots on his record, such as his anti-Semitism and his unhappy family life.

    It covers a sport that has inspired millions and the mountains and snowfall that make it possible. It is not a tale of the end. It is a beginning - a reminder of how dynamic and fulfilling the skiing life is. And a wake-up call regarding what needs to be done to save it.  The narrative follows the unlikely rise of skiing from prehistoric Norwegian hunters to nobility in the Alps in the 1800s to present-day freeriders on the vaunted slopes of the Rocky Mountains. On his global tour of the most celebrated peaks in the Northern Hemisphere, from Washington’s Cascade Range to Mont Blanc and the Matterhorn, Fox talks to alpinists about the allure and mysticism of the sport and to scientists about climate change and its effect on snow—ultimately finding a story that is far larger than the impending demise of skiing.For the seven million skiers in America who dedicate their winters to tracking storms and waking up at dawn to catch the first chairlift, the lifestyle change will be radical. It will likely be far worse for the rest of the world. Fox uses primary evidence and interviews, mixed with groundbreaking scientific studies, to explain exactly how and when the Great Melt will play out, the vital importance snow and ice have to Earth's climate system and the tremendous groundswell that is rising up to fight climate change. DEEP goes on to map a way to mitigate global warming, reduce human impact on our planet and repair the water cycle. As it turns out, the efforts to save snow and ice might end up saving the world."

    Close to a million people—in a nation of 120 million—were forced out of their homes. Some estimates place the death toll in the thousands. The Red Cross fed nearly 700,000 refugees for months. Rising Tide is the story of this forgotten event, the greatest natural disaster this country has ever known. But it is not simply a tale of disaster. The flood transformed part of the nation and had a major cultural and political impact on the rest. Rising Tide is an American epic about science, race, honor, politics, and society. Rising Tide begins in the nineteenth century, when the first serious attempts to control the river began. The story focuses on engineers James Eads and Andrew Humphreys, who hated each other. Out of the collision of their personalities and their theories came a compromise river policy that would lead to the disaster of the 1927 flood yet would also allow the cultivation of the Yazoo-Mississippi Delta and create wealth and aristocracy, as well as a whole culture. In the end, the flood had indeed changed the face of America, leading to the most comprehensive legislation the government had ever enacted, touching the entire Mississippi valley from Pennsylvania to Montana. In its aftermath was laid the foundation for the New Deal of Franklin D. Roosevelt.
