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.

    Devised in India in the 7th and 8th centuries and brought to North Africa by Muslim traders, the Hindu-Arabic system helped transform the West into the dominant force in science, technology, and commerce, leaving behind Muslim cultures which had long known it but had failed to see its potential.The young Italian, Leonardo of Pisa (better known today as Fibonacci), had learned the Hindu number system when he traveled to North Africa with his father, a customs agent. The book he created was Liber abbaci, the "Book of Calculation," and the revolution that followed its publication was enormous. Arithmetic made it possible for ordinary people to buy and sell goods, convert currencies, and keep accurate records of possessions more readily than ever before. Liber abbaci's publication led directly to large-scale international commerce and the scientific revolution of the Renaissance.Yet despite the ubiquity of his discoveries, Leonardo of Pisa remains an enigma. His name is best known today in association with an exercise in Liber abbaci whose solution gives rise to a sequence of numbers--the Fibonacci sequence--used by some to predict the rise and fall of financial markets, and evident in myriad biological structures.One of the great math popularizers of our time, Keith Devlin recreates the life and enduring legacy of an overlooked genius, and in the process makes clear how central numbers and mathematics are to our daily lives.

    A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with nature’s most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.At the end of the seventeenth century—an age of religious wars, plague, and the Great Fire of London—when most people saw the world as falling apart, these earliest scientists saw a world of perfect order. They declared that, chaotic as it looked, the universe was in fact as intricate and perfectly regulated as a clock. This was the tail end of Shakespeare’s century, when the natural land the supernatural still twined around each other. Disease was a punishment ordained by God, astronomy had not yet broken free from astrology, and the sky was filled with omens. It was a time when little was known and everything was new. These brilliant, ambitious, curious men believed in angels, alchemy, and the devil, and they also believed that the universe followed precise, mathematical laws—-a contradiction that tormented them and changed the course of history.The Clockwork Universe is the fascinating and compelling story of the bewildered geniuses of the Royal Society, the men who made the modern world.

    Escher -- goes to some of the strangest spots imaginable. It takes us to a place where the purely intellectual enters our daily world: where our outraged senses, overloaded with grocery bills, the price of gas, and what to eat for lunch, are expected to absorb really bizarre ideas. And no better guide to this weird universe exists than the brilliant thinker Clifford A. Pickover, the 21st century's answer to Buckminster Fuller. Come along as Pickover traces the origins of the Mobius strip from the mid-1800s, when the visionary scientist Dr. August Mobius became the first to describe the properties of one-sided surfaces, to the present, where it is an integral part of mathematics, magic, science, art, engineering, literature, and music. It has become a metaphor for change, strangeness, looping, and rejuvenation. Touching on everything from molecules and metal sculptures to postage stamps, architectural structures, and models of our entire universe, The Mobius Strip is lavishly illustrated and gives readers a glimpse into other worlds and new ways of thinking as Pickover reaches across cultures and dimensions.

    As a member of the Los Alamos National Laboratory from 1944 on, Ulam helped to precipitate some of the most dramatic changes of the postwar world. He was among the first to use and advocate computers for scientific research, originated ideas for the nuclear propulsion of space vehicles, and made fundamental contributions to many of today's most challenging mathematical projects. With his wide-ranging interests, Ulam never emphasized the importance of his contributions to the research that resulted in the hydrogen bomb. Now Daniel Hirsch and William Mathews reveal the true story of Ulam's pivotal role in the making of the "Super," in their historical introduction to this behind-the-scenes look at the minds and ideas that ushered in the nuclear age. An epilogue by Françoise Ulam and Jan Mycielski sheds new light on Ulam's character and mathematical originality.

    But scientists in the late 20th century have found patterns in things formerly thought to be chaotic; their theories help explain the unstable irregular yet highly structured features of everyday experience. It now seems likely that randomness and chaos play an essential role in the evolution of the living world-and of intelligence itself. Script by Dr. Roger White.

     The Moore family were early settlers from Ireland, who eventually made their home in Virginia. A branch of the family discovered Abb’s Valley; a remote settlement, isolated but idyllic, and which had once belonged to Cherokee and Shawnee natives. After many years of happiness, forming a successful and religiously-devoted community, the Moore family was brutally attacked. The Shawnees ruthlessly killed the majority of the family, taking the survivors prisoner, including Mary Moore, James Moore Brown’s mother. Mary found herself sold into slavery, and thus began a long and arduous journey to gain back her freedom and return to the home of youth. With unwavering faith in God and a belief that following His path would set her free, Mary was eventually rescued. This remarkable book, long suppressed because of the politically incorrect facts it contains about early frontier life and the interactions between white settlers and Indians, provides a dramatic insight into the sufferings of the early European pioneers in America. Indians regularly captured whites for use as slaves — although those were the lucky ones. The less fortunate were tortured and killed, often for sport. Written with a strong focus on Presbyterianism, the book’s value lies in its dispassionate detailing of the everyday life and dangers for families on the frontier. Born in Rockbridge, Virginia, USA on 1799 to Samuel Brown and Mary Moore (one of the captives of Abb’s Valley), James Moore Brown married Mary Ann Bell and had 6 children. He passed away on 1866 in Virginia, USA. His only book, The Captives of Abb’s Valley was first published in 1854.

     Born on a Dakota Sioux reservation he was taught the ways of the Native Americans from as soon as he could walk. At the tender age of fourteen, having had little formal education, he was supporting himself and learning from some of the last cowboys and frontiersmen of the Old West. These lessons would pay dividend in his later life, first as a tracker for the United States Army in the Apache Wars and later as a scout for the British Army in the Matebele Wars in Southern Africa. Frederick Burnham Russell was a remarkable figure who revolutionized the art of scouting in both the British and United States armies. Indeed his influence would lead his friend, Robert Baden-Powell, to begin the international Scouting Movement. In Scouting on Two Continents Burnham records the details of his brilliant life in fascinating detail and provides insight into the life of an unique adventurer in the late nineteenth and early twentieth centuries. “Burnham in real life is more interesting than any of my heroes of romance.” Rider Haggard “Burnham is a most delightful companion ... amusing, interesting, and most instructive. Having seen service against the Red Indians he brings quite a new experience to bear on the Scouting work here. And while he talks away there’s not a thing escapes his quick roving eye, whether it is on the horizon or at his feet.” Robert Baden-Powell Frederick Burnham Russell has been described as the “Father of Scouting.” He fought in the Pleasant Valley War, Apache Wars, the First and Second Matabele Wars as well as the Second Boer War. His book Scouting on Two Continents was first published in 1926. He passed away in 1947.

    Underpinning both math and science, it is the foundation of every major advancement in knowledge since the time of the ancient Greeks. Through adventure stories and historical narratives populated with a rich and quirky cast of characters, Mazur artfully reveals the less-than-airtight nature of logic and the muddled relationship between math and the real world. Ultimately, Mazur argues, logical reasoning is not purely robotic. At its most basic level, it is a creative process guided by our intuitions and beliefs about the world.
