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.

    But when Paco was struck down by a disease that left him unable to walk, Hickam was faced with a terrible decision, let his beloved cat live in misery or put him to sleep. Before that decision could be made, the space mission Hickam was working on needed to be rescued and there was only one sure way to save it: Paco's magic meow! This is a true story of the space age that is also a delightful tale of the love between an engineer and his cat.

    Alvarez had the first glimmer of that amazing insight when he noticed something odd in a rock outcrop in central Italy. Alvarez now returns to that rich terrain, this time to take the reader on an excavation of the Earth's distant past. We encounter the volcanoes that formed the Seven Hills of Rome; the majestic limestone Apennine mountains that started to develop millions of years ago under water; the evidence that the Mediterranean Sea completely evaporated to a sunken desert, perhaps several times; and the proof that continental plates once overran one another to form the Alps. In Alvarez's telling, all major geologic episodes are as dramatic as the great impact that killed the dinosaurs, even when they happen over eons and without huge creatures to witness them.

    G. Lord was becoming a teenager in Southern California and her mother was dying of cancer, Lord's father-an archetypal, remote, rocket engineer- disappeared into his work at the Jet Propulsion Laboratory in Pasadena, building the space probes of the Mariner Mars 69 mission. Thirty years later, Lord found herself reporting on the JPL, triggering childhood memories and a desire to revisit her past as a way of understanding the ethos of rocket science. Astro Turf is the brilliant result of her journey of discovery.Remembering her pain at her father's absence, yet intrigued by what he did, Lord captures him on the page as she recalls her own youthful, eccentric fascination with science and space exploration. Into her family's saga she weaves the story of the legendary JPL- examining the complexities of its cultural history, from its start in 1936 to the triumphant Mars landings in 2004. She illuminates its founder, Frank Malina, whose brilliance in rocketry was shadowed by a flirtation with communism, driving him from the country even as we welcomed Wernher von Braun and his Nazi colleagues. Lord's own love of science fiction becomes a lens through which she views a profound cultural shift in the male-dominated world of space. And in pursuing the cause of her father's absence she stumbles on a hidden guilt, understanding "the anguish his proud silence caused both him and me, and how rooted that silence was in the culture of engineering."As in her acclaimed book Forever Barbie, which demystified an icon of feminine culture, Lord brings her penetrating insight to bear on a bastion of American masculinity, opening our eyes in unexpected and memorable ways.

     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.

    Not until the nineteenth century would three men, armed with the best telescopes of their age, race to conquer this astronomical Everest. Parallax tells the fast-moving story of their contest, which ended in a dead heat. Against a sweeping backdrop filled with kidnappings, dramatic rescue, swordplay, madness, and bitter rivalry, Alan W. Hirshfeld brings to life the heroes -- and heroines -- of this remarkable chapter in history. Characters include the destitute boy plucked from a collapsed building who grew up to become the world's greatest telescope maker; the hot-tempered Dane whose nose was lopped off in a duel over mathematics; a merchant's apprentice forced to choose between the lure of money and his passion for astronomy; and the musician who astounded the world by discovering a new planet from his own backyard.Generously illustrated with period engravings and paintings, Parallax is an unforgettable ride through time and space.

    Neither of those works, however, undertakes to give a detailed account of the great Anarchy that marked the conclusion of the eighteenth century, the dark time that came before the dawn of British power in the land of the Moghul.

    Once in a while, you come across someone who had the energy and determination to see it through and you are happy he did. Such is the case with Justin Dwayne Foxworth in his breakout novel, Valerie. I highly recommend you give a new talent a chance and read his work. I'm sure you'll want more of his character development and plots developed into more novels to enjoy... Andrew Neiderman, author of The Devil's Advocate

    Right?! Machine Learning is a branch of computer science that wants to stop programming computers using a detailed list of commands to follow blindly. Instead, their aim is to implement high-level routines that teach computers how to approach new and unknown problems – these are called algorithms. In practice, they want to give computers the ability to Learn and to Adapt. We can use these algorithms to obtain insights, recognize patterns and make predictions from data, images, sounds or videos we have never seen before – or even knew existed. Unfortunately, the true power and applications of today’s Machine Learning Algorithms remain deeply misunderstood by most people. Through this book I want fix this confusion, I want to shed light on the most relevant Machine Learning Algorithms used in the industry. I will show you exactly how each algorithm works, why it works and when you should use it.

    S. Marine long range reconnaissance teams during the Vietnam War, Andrew Finlayson recounts his team's experiences in the year leading up to the Tet Offensive of 1968. Using primary sources, such as Marine Corps unit histories and his own weekly letters home, he presents a highly personal account of the dangerous missions conducted by this team of young Marines as they searched for North Vietnamese Army and Viet Cong units in such dangerous locales as Elephant Valley, the Enchanted Forest, Charlie Ridge, Happy Valley and the Que Son Mountains. In numerous close contacts with the enemy, the team (code-name Killer Kane) fights for its survival against desperate odds, narrowly escaping death time and again. The book gives vivid descriptions of the life of recon Marines when they are not on patrol, the beauty of the landscape they traverse, and several of the author's Vietnamese friends.

    The truth is: politics and innuendo clouded that story from the very beginning, with the result that few people really understand who The Duke and Duchess of Windsor were and what forces propelled them to their infamous fate. The Royal W.E. examines the individual and intertwined lives of Wallis and Edward – or “W.E.” as they referred to themselves – and provides readers with unique glimpses of the real people, as opposed to the sensationalized characters, that were The Duke and Duchess of Windsor. Through careful study of more than 75 years of rhetoric and scholarship, Victoria Martínez takes on the most controversial charges lodged against the couple (Was Wallis a hermaphrodite? Were the Duke and Duchess Nazi sympathizers?) with candor and evenhandedness. In analyzing the early lives of Wallis and the ex-king and their later relationships with other members of the Royal Family, her approach is to deal with all parties as human beings, whose true faults – though significant – were far less sinister than history has led us to believe. Ms. Martínez also addresses the ever-popular subject of the Duchess’s jewels, including new research on the famous 1946 Ednam Lodge jewel heist to dispel the long-held rumors that the Duke and Duchess committed jewel theft and insurance fraud. The subjects in this book are not always mainstream, well-known, or even consistent with “popular” opinion, and the objective is not to make anyone “like” the couple. Instead, readers will find refreshingly honest and accurate portrayals of W.E. that will help them understand the real people behind the myth and hype. “Prejudice and preconception are difficult things to set aside, particularly after so many years of negative stories and sordid rumor, but I think readers here will discover an alternative and convincing look at the Duke and Duchess of Windsor. I am sure they would approve and perhaps, just perhaps, the future may be a little bit kinder to Edward and Wallis because of the efforts of people like Ms. Martínez.” -Greg King, author of The Duchess of Windsor: The Uncommon Life of Wallis Simpson

    The chafing restrictions of a typical upbringing in upper-class, small town Alabama simply did not apply to Zelda, who was described as an unusual child and permitted to roam the streets with little supervision. Zelda refused to blossom into a typical 'Southern belle' on anyone's terms but her own and while still in high school enjoyed the status of a local celebrity for her shocking behavior. Everybody in town knew the name Zelda Sayre. Queen of the Montgomery social scene, Zelda had a different beau ready and willing to show her a good time for every day of the week. Before meeting F. Scott Fitzgerald, Zelda's life was a constant pursuit of pleasure. With little thought for the future and no responsibilities to speak of, Zelda committed herself fully to the mantra that accompanied her photo in her high school graduation book: "Why should all life be work, when we all can borrow. Let's think only of today, and not worry about tomorrow." But for now Zelda was still in rehearsal for her real life to begin, a life she was sure would be absolutely extraordinary. Zelda Sayre married F. Scott Fitzgerald on the 3rd of April 1920 and left sleepy Montgomery behind in order to dive headfirst into the shimmering, glamourous life of a New York socialite. With the publication of Scott's first novel, This Side of Paradise, Zelda found herself thrust into the limelight as the very epitome of the Flapper lifestyle. Concerned chiefly with fashion, wild parties and flouting social expectations, Zelda and Scott became icons of the Jazz Age, the personification of beauty and success. What Zelda and Scott shared was a romantic sense of self-importance that assured them that their life of carefree leisure and excess was the only life really worth living. Deeply in love, the Fitzgeralds were like to sides of the same coin, each reflecting the very best and worst of each other. While the world fell in love with the image of the Fitzgeralds they saw on the cover of magazines, behind the scenes the Fitzgerald's marriage could not withstand the tension of their creative arrangement. Zelda was Scott's muse and he mercilessly mined the events of their life for material for his books. Scott claimed Zelda's memories, things she said, experiences she had and even passages from her diary as his possessions and used them to form the basis of his fictional works. Zelda had a child but the domestic sphere offered no comfort or purpose for her. The Flapper lifestyle was not simply a phase she lived through, it formed the very basis of her character and once the parties grew dull, the Fitzgeralds' drinking became destructive and Zelda's beauty began to fade, the world held little allure for her. Zelda sought reprieve in work and tried to build a career as a ballet dancer. When that didn't work out she turned to writing but was forbidden by Scott from using her own life as material. Convinced that she would never leave her mark on the world as deeply or expressively as Scott had, Zelda retreated into herself and withdrew from the people she knew in happier times. The later years of Zelda's life were marred by her detachment from reality as, diagnosed with schizophrenia, Zelda spent the last eighteen years of her life living in and out of psychiatric hospitals. As Scott's life unraveled due to alcohol abuse, Zelda looked back on the years they had spent together, young and wild and beautiful, as the best of her life. She may have been right but she was wrong about one thing, Zelda did leave her mark on the world and it was a deep and expressive mark that no one could have left but her. Zelda Fitzgerald: The Biography

    The God series fully reveals what Pythagoras meant. Mathematics - built from numbers - is not an abstraction but is ontological: it actually exists. Numbers are real things. Specifically, they are the frequencies of energy waves. (Moreover, energy waves are simply sinusoidal waves: sines and cosines, meaning that the study of energy is the study of sinusoids). There are infinite energy waves, hence infinite numbers. No numbers are privileged over any others, so negative and imaginary numbers are as ontologically important as real numbers (upon which science is exclusively based).Real numbers correspond to space and imaginary numbers to time. Negative numbers are "antimatter": a mirror image universe.The two most powerful numbers of all - and the ultimate basis of Illuminist thinking - are zero and infinity, which are harnessed together ontologically (opposite sides of the same coin, so to speak). The existence of zero and infinity is vehemently denied by the ideology of scientific materialism. In Illuminism, these two numbers not only exist, they are the "God" numbers: the origin of all other numbers. Zero and infinity comprise the Big Bang Singularity itself from which an infinitely large universe emerged: "everything" literally came from "nothing".Moreover, zero is also the "monad" of Leibniz (an Illuminati Grand Master). It is therefore the number of THE SOUL, and it has INFINITE capacity. Being dimensionless - a mathematical point - the soul is outside the dimensional, material domain of space and time, hence the soul is indestructible, immortal and cannot be detected by any conventional scientific experiment.What we are describing are the necessary, analytic, eternal truths of mathematics - they have no connection with Abrahamic religious faith. There is NO Creator God but, astoundingly, each soul is capable of being promoted to God status, just as the pawn in chess can become the most important chess piece, the Queen, if it reaches the other side of the battlefield (the board). In Illuminism, if you reach gnosis - enlightenment - you become God.Mathematics is literally everything. Unlike science, mathematics offers certainty: 100% true and incontestable knowledge. Mathematics unifies science, religion and metaphysics. Mathematics is the true Grand Unified Theory of Everything that science pursues so futilely. Science can never deliver truth and certainty because it is inherently a succession of provisional theories, any of which can be overturned at any time by new experimental data. Science is based on ideas of validation and falsification. Mathematics is based on absolute analytic and unarguable certainty. No experiment can ever contradict a mathematical truth.Mathematics is the ONLY answer to everything. Mathematics is the ONLY subject inherently about eternal, Platonic truth. As soon as existence is understood to be nothing but ontological mathematics, all questions are ipso facto answered.The God series, starting with The God Game, reveals the astonishing power of ontological mathematics to account for everything, including things such as free will, irrationalism, emotion, consciousness and qualia, which seem to have no connection with mathematics.Read the God series and you will become a convert to the world's only rational religion - Illuminism, the Pythagorean religion of mathematics that infallibly explains all things and guarantees everyone a soul that is not only eternal but also has the capacity to make of each of us a true God.Isn't it time to become Illuminated?
