Ask them the meaning of 'relativity' and few of them will be able to tell you what it is.The basic principles of relativity have not changed since Russell first published his lucid guide for the general reader. The ABC of Relativity is Bertrand Russell's most brilliant work of scientific popularisation. With marvellous lucidity he steers the reader who has no knowledge of maths or physics through the subtleties of Einstein's thinking. In easy, assimilable steps, he explains the theories of special and general relativity and describes their practical application to, amongst much else, discoveries about gravitation and the invention of the hydrogen bomb.

    It is one of the most devastating episodes in the history of the twentieth century. With unprecedented authority and detail, Red Famine investigates how this happened, who was responsible, and what the consequences were. It is the fullest account yet published of these terrible events.The book draws on a mass of archival material and first-hand testimony only available since the end of the Soviet Union, as well as the work of Ukrainian scholars all over the world. It includes accounts of the famine by those who survived it, describing what human beings can do when driven mad by hunger. It shows how the Soviet state ruthlessly used propaganda to turn neighbours against each other in order to expunge supposedly 'anti-revolutionary' elements. It also records the actions of extraordinary individuals who did all they could to relieve the suffering.The famine was rapidly followed by an attack on Ukraine's cultural and political leadership - and then by a denial that it had ever happened at all. Census reports were falsified and memory suppressed. Some western journalists shamelessly swallowed the Soviet line; others bravely rejected it, and were undermined and harassed. The Soviet authorities were determined not only that Ukraine should abandon its national aspirations, but that the country's true history should be buried along with its millions of victims. Red Famine, a triumph of scholarship and human sympathy, is a milestone in the recovery of those memories and that history. At a moment of crisis between Russia and Ukraine, it also shows how far the present is shaped by the past.

    Here, for the first time, is the complete history of the quest to understand Earth’s magnetism—from the ancient Greeks’ fascination with lodestone, to the geological discovery that the North Pole has not always been in the North—and to the astonishing modern conclusions that finally revealed the true source.Richly illustrated and skillfully told, North Pole, South Pole unfolds the human story behind the science: that of the inquisitive, persevering, and often dissenting thinkers who unlocked the secrets at our planet’s core.

     Of all the cities of ancient Mesopotamia, Babylon is virtually the only one which is still remembered today. The very word Babylon has entered the lexicon of popular understanding as a synonym for decadence and wealth. But what do we really know about the history of this once mighty city? Inside you will read about... ✓ King Hammurabi and the Babylonian Empire ✓ The Persian Conquest ✓ Alexander the Great Enters Babylon ✓ Babylon Falls ✓ Babylon in the Bible And much more! Babylon first became important in the eighteenth century BCE under the rule of King Hammurabi. However, it barely survived his death before it was conquered, first by the Hittites and then by the Assyrians. In the seventh century BCE, the city was completely destroyed after it rebelled against Assyrian rule, and it wasn’t until the reign of King Nebuchadnezzar II that it once again became the heart of a large empire. After that, it was conquered by the Persians and finally, in the fourth century BCE, by Alexander the Great. Alexander planned to make Babylon the capital of his mighty empire, but he died in the city under mysterious circumstances before this was done. After his death, Babylon entered a period of decline from which it never recovered until by the seventh century CE it was no more than a source of bricks for local builders. How did this happen? How did this city rise to great power and then fall to become nothing but a memory? Why do we remember the name of Babylon when the names of all the other great cities of ancient Mesopotamia have been forgotten? This is the story of Babylon.

    Sixteen weeks later, Frank Borman, Jim Lovell, and Bill Anders were aboard the first manned spacecraft to depart Earth’s orbit, reach the moon, and return safely to Earth, delivering a tear-inducing Christmas Eve message along the way.

    It would become the world's most baffling mathematical mystery. Simple, elegant, and utterly impossible to prove, Fermat's Last Theorem captured the imaginations of amateur and professional mathematicians for over three centuries. For some it became a wonderful passion. For others it was an obsession that led to deceit, intrigue, or insanity. In a volume filled with the clues, red herrings, and suspense of a mystery novel, Dr. Amir Aczel reveals the previously untold story of the people, the history, and the cultures that lie behind this scientific triumph. From formulas devised for the farmers of ancient Babylonia to the dramatic proof of Fermat's theorem in 1993, this extraordinary work takes us along on an exhilarating intellectual treasure hunt. Revealing the hidden mathematical order of the natural world in everything from stars to sunflowers, "Fermat's Last Theorem" brilliantly combines philosophy and hard science with investigative journalism. The result: a real-life detective story of the intellect, at once intriguing, thought-provoking, and impossible to put down.

    In 2013, the New York Times published an obituary for Yvonne Brill. It began: “She made a mean beef stroganoff, followed her husband from job to job, and took eight years off from work to raise three children.” It wasn’t until the second paragraph that readers discovered why the Times had devoted several hundred words to her life: Brill was a brilliant rocket scientist who invented a propulsion system to keep communications satellites in orbit, and had recently been awarded the National Medal of Technology and Innovation. Among the questions the obituary—and consequent outcry—prompted were, Who are the role models for today’s female scientists, and where can we find the stories that cast them in their true light?      Headstrong delivers a powerful, global, and engaging response. Covering Nobel Prize winners and major innovators, as well as lesser-known but hugely significant scientists who influence our every day, Rachel Swaby’s vibrant profiles span centuries of courageous thinkers and illustrate how each one’s ideas developed, from their first moment of scientific engagement through the research and discovery for which they’re best known. This fascinating tour reveals these 52 women at their best—while encouraging and inspiring a new generation of girls to put on their lab coats.

    Radiation: What could go wrong? In short, plenty. From Marie Curie carrying around a vial of radium salt because she liked the pretty blue glow to the large-scale disasters at Chernobyl and Fukushima, dating back to the late nineteenth century, nuclear science has had a rich history of innovative exploration and discovery, coupled with mistakes, accidents, and downright disasters. In this lively book, long-time advocate of continued nuclear research and nuclear energy James Mahaffey looks at each incident in turn and analyzes what happened and why, often discovering where scientists went wrong when analyzing past meltdowns. Every incident, while taking its toll, has led to new understanding of the mighty atom—and the fascinating frontier of science that still holds both incredible risk and great promise.

    Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

    When Christian armies seized Jerusalem in 1099, they began the most notorious period of conflict between the two religions. Depending on who you ask, the fall of the holy city was either an inspiring legend or the greatest of horrors. In Crusaders, Dan Jones interrogates the many sides of the larger story, charting a deeply human and avowedly pluralist path through the crusading era.Expanding the usual timeframe, Jones looks to the roots of Christian-Muslim relations in the eighth century and tracks the influence of crusading to present day. He widens the geographical focus to far-flung regions home to so-called enemies of the Church, including Spain, North Africa, southern France, and the Baltic states. By telling intimate stories of individual journeys, Jones illuminates these centuries of war not only from the perspective of popes and kings, but from Arab-Sicilian poets, Byzantine princesses, Sunni scholars, Shi'ite viziers, Mamluk slave soldiers, Mongol chieftains, and barefoot friars. Crusading remains a rallying call to this day, but its role in the popular imagination ignores the cooperation and complicated coexistence that were just as much a feature of the period as warfare. The age-old relationships between faith, conquest, wealth, power, and trade meant that crusading was not only about fighting for the glory of God, but also, among other earthly reasons, about gold. In this richly dramatic narrative that gives voice to sources usually pushed to the margins, Dan Jones has written an authoritative survey of the holy wars with global scope and human focus.

    Filled with surprising stories of accidental genius and brilliant mistakes—from the French publisher who invented the phonograph before Edison but forgot to include playback, to the Hollywood movie star who helped invent the technology behind Wi-Fi and Bluetooth—How We Got to Now investigates the secret history behind the everyday objects of contemporary life. In his trademark style, Johnson examines unexpected connections between seemingly unrelated fields: how the invention of air-conditioning enabled the largest migration of human beings in the history of the species—to cities such as Dubai or Phoenix, which would otherwise be virtually uninhabitable; how pendulum clocks helped trigger the industrial revolution; and how clean water made it possible to manufacture computer chips. Accompanied by a major six-part television series on PBS, How We Got to Now is the story of collaborative networks building the modern world, written in the provocative, informative, and engaging style that has earned Johnson fans around the globe.

    David Abulafia's The Great Sea is the first complete history of the Mediterranean, from the erection of temples on Malta around 3500 BC to modern tourism. Ranging across time and the whole extraordinary space of the Mediterranean from Gibraltar to Jaffa, Genoa to Tunis, and bringing to life pilgrims, pirates, sultans and naval commanders, this is the story of the sea that has shaped much of world history.

    Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    In three successive waves, from 1918 to 1919, influenza killed more than 50 million people. German soldiers termed it Blitzkatarrh, British soldiers referred to it as Flanders Grippe, but world-wide, the pandemic gained the notorious title of “Spanish Flu." Nowhere on earth escaped: the United States recorded 550,000 deaths (five times its total military fatalities in the war), while European deaths totaled more than two million.Amid the war, some governments suppressed news of the outbreak. Even as entire battalions were decimated, with both the Allies and the Germans suffering massive casualties, the details of many servicemen’s deaths were hidden to protect public morale. Meanwhile, civilian families were being struck down in their homes. Philadelphia ran out of gravediggers and coffins, and mass burial trenches had to be excavated with steam shovels. Spanish flu conjured up the specter of the Black Death of 1348 and the great plague of 1665, while the medical profession, shattered after five terrible years of conflict, lacked the resources to contain and defeat this new enemy. Through primary and archival sources, historian Catharine Arnold gives readers the first truly global account of this terrible epidemic.

    Supernatural magic is what our ancestors used in order to explain the world before they developed the scientific method. The ancient Egyptians explained the night by suggesting the goddess Nut swallowed the sun. The Vikings believed a rainbow was the gods’ bridge to earth. The Japanese used to explain earthquakes by conjuring a gigantic catfish that carried the world on its back—earthquakes occurred each time it flipped its tail. These are magical, extraordinary tales. But there is another kind of magic, and it lies in the exhilaration of discovering the real answers to these questions. It is the magic of reality—science.Packed with clever thought experiments, dazzling illustrations and jaw-dropping facts, The Magic of Reality explains a stunningly wide range of natural phenomena. What is stuff made of? How old is the universe? Why do the continents look like disconnected pieces of a puzzle? What causes tsunamis? Why are there so many kinds of plants and animals? Who was the first man, or woman? This is a page-turning, graphic detective story that not only mines all the sciences for its clues but primes the reader to think like a scientist as well.Richard Dawkins, the world’s most famous evolutionary biologist and one of science education’s most passionate advocates, has spent his career elucidating the wonders of science for adult readers. But now, in a dramatic departure, he has teamed up with acclaimed artist Dave McKean and used his unrivaled explanatory powers to share the magic of science with readers of all ages. This is a treasure trove for anyone who has ever wondered how the world works. Dawkins and McKean have created an illustrated guide to the secrets of our world—and the universe beyond—that will entertain and inform for years to come.
