Modifying Copernicus's sun-centered model of the universe, Kepler's 1619 work went on to establish laws of planetary motion, forming the basis for Newton's discoveries some 60 years later. As part of our On the Shoulders of Giants series, this translation of the original edition of Kepler's monumental essay includes an insightful biography and a highly accessible summary putting into context the significance of Harmony of the World.

    They set the ball rolling and wealth simply accumulates. They let their money work for them. For the author, the combination of a book, a game, a woman and an opportunity helped him get out of the rat race onto the fast track. Discover why most Pinoys are poor and the secrets of the rich Tsinoys.

    Guth’s startling theory—widely regarded as one of the most important contributions to science during the twentieth century—states that the big bang was set into motion by a period of hyper-rapid “inflation,” lasting only a billion-trillion-billionth of a second. The Inflationary Universe is the passionate story of one leading scientist’s effort to look behind the cosmic veil and explain how the universe began.

    Sometimes provocative, sometimes fanciful, always elegantly conceived and written, these meditations offer readers a fascinating look into the creative compulsions shared by the scientist and the artist. Reading tour.

    It is a way of thinking, feeling, deciding, doing, and then getting the results and feedback accordingly to build momentum and get closer to your vision and legacy. Life Leverage doesn't 'end' with sitting on a beach drinking Pina Colada's, or retirement, or freedom, or balance. It allows you to live that moment-to-moment, or whatever that 'end goal' is to you, now, and not rear-loaded, merging your passion with your profession and your vocation with your vacation. The Life Leverage philosophy is living a fulfilled and inspired life, in balance of passion and profession, without overly sacrificing either. The Life Leverage philosophy doesn't understand 'work/life' balance or separation; it merges every aspect into one inspired life. The Life Leverage philosophy understands and accepts the balance of ups and downs, happiness and sadness, and moves towards its vision and legacy, constantly tweaking and accepting feedback. It disdains duplication and wastage; getting maximum leverage and maximum time preservation with minimum time erosion and wastage. It doesn't rear-load retirement, instead it lives continual mini-retirements.

    And two giants at the foundations of modern science were converging, step-by-step, on the answer: Albert Einstein, an young, obscure German physicist experimenting with measuring time using telegraph networks and with the coordination of clocks at train stations; and the renowned mathematician Henri Poincaré, president of the French Bureau of Longitude, mapping time coordinates across continents. Each found that to understand the newly global world, he had to determine whether there existed a pure time in which simultaneity was absolute or whether time was relative.Esteemed historian of science Peter Galison has culled new information from rarely seen photographs, forgotten patents, and unexplored archives to tell the fascinating story of two scientists whose concrete, professional preoccupations engaged them in a silent race toward a theory that would conquer the empire of time.

    Repchecks riveting story tells of the enigmatic genius responsible for one of the most important scientific theories ever--and why it took several decades and a strangers intervention before his groundbreaking On the Revolutions of the Heavenly Spheres was published.

    Yet Greg's route to the very top was never smooth. He always believed in himself as an athlete and sportsman, but for many years could not find an outlet that allowed him to truly excel.       During his reckless teenage years, he would sometimes sleep rough or indulge in dangerous games such as car surfing, before he found the focus that would help him to get to the very top. But even then, there were still setbacks, as when he fell short in the Beijing Olympics. It served only to spur him on. In London, he became a part of 'Super Saturday' when he joined Mo Farah and Jessica Ennis in winning gold in 45 astonishing minutes of British glory. Condemned by some as a 'lucky' winner, he went on to complete his clean sweep of major titles through sheer determination to succeed. In this long-awaited memoir, he not only reveals the secrets of his remarkable success, but also has plenty to say on the issues that are dominating athletics, such as doping, and much else besides. It is a raw, passionate, entertaining and fascinating read.

    Johannes Kepler, who discovered the three basic laws of planetary motion, was persecuted for his support of the Copernican system. After a neighbour accused his mother of witchcraft, Kepler quit his post as the Imperial mathematician to defend her.James Connor tells Kepler's story as a pilgrimage, a spiritual journey into the modern world through war and disease and terrible injustice, a journey reflected in the evolution of Kepler's geometrical model of the cosmos into a musical model, harmony into greater harmony. The leitmotif of the witch trial adds a third dimension to Kepler's biography by setting his personal life within his own times. The acts of this trial, including Kepler's letters and the accounts of the witnesses, although published in their original German dialects, had never before been translated into English. Echoing some of Dava Sobel's work for Galileo's Daughter, Connor has translated the witch trial documents into English. With a great respect for the history of these times and the life of this man, Connor's accessible story illuminates the life of Kepler, the man of science, but also Kepler, a man of uncommon faith and vision.

    From the observations of Ptolemy and Kepler to the Harmony of the Spheres and the hidden structure of the solar system, John Martineau reveals the exquisite orbital patterns of the planets and the mathematical relationships that govern them. A table shows the relative measurements of each planet in eighteen categories, and three pages show the beautiful dance patterns of thirty six pairs of planets and moons.

    Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernican system over the Ptolemaic one, proving, for the first time, that the earth revolves around the sun. Its influence is incalculable. The Dialogue is not only one of the most important scientific treatises ever written, but a work of supreme clarity and accessibility, remaining as readable now as when it was first published. This edition uses the definitive text established by the University of California Press, in Stillman Drake’s translation, and includes a Foreword by Albert Einstein and a new Introduction by J. L. Heilbron.

    Whether they've arrived via rocket, flying saucer, or plain old teleportation, they've been invading, infiltrating, or inspiring us for decades, and they've fascinated moviegoers and television watchers for more than fifty years. About half of us believe that aliens really exist, and millions are convinced they've visited Earth. For twenty-five years, SETI has been looking for the proof, and as the program's senior astronomer, Seth Shostak explains in this engrossing book, it's entirely possible that before long conclusive evidence will be found. His informative, entertaining report offers an insider's view of what we might realistically expect to discover light-years away among the stars. Neither humanoids nor monsters, says Shostak; in fact, biological intelligence is probably just a precursor to machine beings, enormously advanced artificial sentients whose capabilities and accomplishments may have developed over billions of years and far exceed our own. As he explores what, if anything, they would tell us and what their existence would portend for humankind and the cosmos, he introduces a colorful cast of characters and provides a vivid, state-of-the-art account of the past, present, and future of our search for extraterrestrial intelligence.

    This essay by Copernicus (1473-1543), revolutionized the way we look at the earth's placement in the universe, and paved the way for many great scientists, including Galileo and Isaac Newton, whose theories stemmed from this model. Featuring a biography of Copernicus and an accessible, enlightening introduction, both written by the renowned physicist Stephen Hawking, On the Revolution of Heavenly Spheres provides a fascinating look at the theories which shaped our modern understanding of astronomy and physics.

     Peter Meyer grew up on an African game reserve. His idyllic childhood was spent running wild in the bush with Zulu friends and other free spirits. His adventures in the wilderness honed his character, nurtured by an inspirational father who taught him to believe that everything is possible. Before he had turned eight he had survived Rhino attacks, close encounters with Buffalo and Wildebeest — and the terror of twice being bitten by snakes. His pets were a baby Elephant, Warthogs and an Ostrich that frequented his backyard. He lived in a world where beauty was tempered by daily struggles for survival. He discovered that the reality of the bush is often heart-breaking, such as when an Nyala doe that he had hand-reared was taken by predators. He learned through first-hand experience that the cycle of life on Africa’s feral outbacks can be as unforgiving as it is magnificent. These were the key lessons from the wilds of Africa that he took with him when his family left the continent; from school days in England where his tough upbringing resulted in being a top sportsman, to studying at an exclusive Swiss hotel school and becoming one of the youngest directors in the Hilton group, managing exotic resorts in Jamaica and the Middle East. He was on top of the world when everything came crashing down due to tragedy. Drawing on resilience learned in the African bush, he started to rebuild his life, becoming an actor and model, clawing his way up in one of the most critically demanding industries in the world. This is an inspiring true story of living the dream — a dream nurtured by the freedom and self-reliance of growing up wild in Africa.
