A man of faith ordained in the Protestant tradition, Heino Falcke wrestles with the ways in which black holes force us to confront the boundary where human life ends and the celestial begins. He also ponders why black holes are difficult for most of us to understand—comparing it to our inability to envisage our own inevitable death.Black holes develop in outer space when a massive star dies, and its matter is condensed. That extreme amount of mass contained in a small space generates a gigantic amount of gravitational force, allowing the black hole to suck up everything that comes near, including light. These astronomical wonders are the subject of our greatest scientific and philosophical theorizing—the journey to a black hole would be the journey to the end of time itself. In this way, Falcke regards them as the most exquisite representations of fear, death . . . and, surprisingly, the divine.Empirical and profound, A Light in the Darkness is the first work to examine both the physical nature and spiritual meaning of black holes, those astrophysical mysteries Falcke, calls “the epitome of merciless destruction.”

    . . . Readers will never again look into the night sky the same way.” —MICHAEL SHERMER, author of The Believing Brain on Parallax: The Race to Measure the CosmosIn 1930, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed; the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement. In its shadow lies an untold, yet equally fascinating, backstory whose cast of characters illuminates the gritty, hard-won nature of scientific progress.The path to a broader mode of cosmic observation was blazed by a cadre of 19th-century amateur astronomers and inventors, galvanized by the advent of photography, spectral analysis, and innovative technology to create the entirely new field of astrophysics. From William Bond, who turned his home into a functional observatory, to John and Henry Draper, a father and son team who were trailblazers of astrophotography and spectroscopy, to geniuses of invention such as Léon Foucault, and George Hale, who founded the Mount Wilson Observatory, Hirshfeld reveals the incredible stories—and the ambitious dreamers—behind the birth of modern astronomy.Alan Hirshfeld, Professor of Physics at the University of Massachusetts Dartmouth and an Associate of the Harvard College Observatory, is the author of Parallax: The Race to Measure the Cosmos, The Electric Life of Michael Faraday, and Eureka Man: The Life and Legacy of Archimedes.

    

    Whether it is Hannibal of Carthage marching elephants across the Alps and attacking the heart of Rome, Khalid ibn al-Walid boasting an undefeated military career and destroying the Persian Empire while subduing the Byzantines, or Russian General Alexander Suvurov and his elevation of the bayonet to a work of art that could cut down any European army, great military leaders have exerted tremendous influence on society. This book will look at the lives of the ten greatest military commanders in history. Some conquered the fullest expanse of the known world, as did Alexander the Great. Still others were master statesmen and capable of translating military victory into long-term political gains, such as Julius Caesar, whose vanquishing of the Gauls and his political opponents laid the groundwork for several centuries of unmatchable Roman imperial might. It will also look at the tactics they used to bring down stronger armies and befuddle them at every turn; whether it is Napoleon, who nearly conquered Europe through his deadly manoeuvre sur les derrieres and marching unexpectedly away from the enemy's main strength and concentrating on a weak but vital enemy point; or Hannibal's double entrapment maneuver, which has been the envy of military strategists for the last 2,000 years. Whatever their background, these rulers show that the right military commander at the right time in history can destroy an empire, change civilization, and alter the course of world history forever.

    Before the Big Bang, there was a tiny fraction of a second during which a process called inflation expanded a seed much smaller than the nucleus of an atom into a fireball the size of a basketball -- the Big Bang itself. From this fireball, the Universe as we know it developed. The origin of the seed from which the Universe began is not known with certainty, but as John Gribbin explains the most likely explanation is that it was a fluctuation of quantum energy in an eternal sea of cosmic energy. And that means that other seeds must surely have inflated to become other universes, bubbles in the cosmic sea. It is even possible that a collision between our universe and another bubble on the sea of eternity may have left an imprint on the cosmic background radiation, the echo of the Big Bang itself. John Gribbin is an award winning science writer best known for his book In Search of Schrodinger's Cat. He studied astrophysics under Fred Hoyle in Cambridge, and is now a Visiting Fellow in Astronomy at the University of Sussex.

    Not only the result of a carving of Korean territories following the Pacific conflicts of the Second World War, it was also a battle of ideologies as General MacArthur’s American military forces occupied the southern half and Stalin’s Soviet forced supported the northern half.Initiated by infantry movements and air raids, the region gradually became mired in a static trench war by July 1951, and would continue to cost both sides in both morale and human lives. The Korean War: History in an Hour is the concise story to one of the most bitter and enduring conflicts of the post-war era.

    In Coming Apocalypse he explains how and why the 'crisis' developed and explains the sort of future we can expect now that lockdowns have destroyed the global economy and changed our way of life. Our world will never be as it was in January 2020. Dr Coleman explains what he believes we can expect.

    It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behaviour of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its intellectual giants, from Albert Einstein to Stephen Hawking, over the strange paradoxes and implications that seem like the stuff of fantasy. Whether it's Schr�dinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory is what challenges our fundamental assumptions about our reality. In Einstein's Unfinished Revolution, globally renowned theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved for the simple reason that the theory is incomplete. There is more, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond it to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed the field, before wrestling with the puzzles and conundrums that they present. Along the way, he illuminates the existing theories about the quantum world that might solve these problems, guiding us toward his own vision that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics as we know it to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

    He decried the internment of Japanese-Americans in World War Two, agitated against nuclear weapons, promoted vitamin C as a cure for the common cold and researched the idea of DNA.

    Michael Savage explains the origins of viruses and their impact on the U.S. With new and resurgent diseases resulting from unregulated immigration and a politicized public health system, Michael Savage sees the need for some changes - starting with the President and the Center for Disease Control telling us the truth. Savage makes his case for the government to enforce travel bans, the use of quarantines and the importance of proper border screenings. However, this is not a cure or treatment for any of these diseases. With Zika virus, tuberculosis, hepatitis, Enterovirus 68 and other new disease threats emerging across the U.S., Savage will explain ways to fortify your immune system and defend against these and other diseases. Drawing from his extensive training, Dr. Savage examines the benefits of using specific nutrients to boost the human immune system which, in turn, increases the odds of surviving a viral infection as well as preventing other diseases. Based on his knowledge of the politics of medicine being played by the Obama mandarins and his Ph.D. in Epidemiology and Nutrition from the University of California, Berkley, Dr. Savage presents solid information to protect your health. Whether you want to defend your body against deadly diseases, boost your immunity, or learn more about the government's impact on reemerging and imported diseases, DISEASES WITHOUT BORDERS is your source for informative, helpful, and potentially life-saving advice.

    In A Brief History of Mathematical Thought, Luke Heaton explores how the language of mathematics has evolved over time, enabling new technologies and shaping the way people think. From stone-age rituals to algebra, calculus, and the concept of computation, Heaton shows the enormous influence of mathematics on science, philosophy and the broader human story. The book traces the fascinating history of mathematical practice, focusing on the impact of key conceptual innovations. Its structure of thirteen chapters split between four sections is dictated by a combination of historical and thematic considerations. In the first section, Heaton illuminates the fundamental concept of number. He begins with a speculative and rhetorical account of prehistoric rituals, before describing the practice of mathematics in Ancient Egypt, Babylon and Greece. He then examines the relationship between counting and the continuum of measurement, and explains how the rise of algebra has dramatically transformed our world. In the second section, he explores the origins of calculus and the conceptual shift that accompanied the birth of non-Euclidean geometries. In the third section, he examines the concept of the infinite and the fundamentals of formal logic. Finally, in section four, he considers the limits of formal proof, and the critical role of mathematics in our ongoing attempts to comprehend the world around us. The story of mathematics is fascinating in its own right, but Heaton does more than simply outline a history of mathematical ideas. More importantly, he shows clearly how the history and philosophy of maths provides an invaluable perspective on human nature.
