Buried there lie answers about the origins of humankind. After a century of investigation, scientists have transformed our understanding about the beginnings of human life. But vital clues still remain hidden. In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies as well as their feats of skill and endurance.The results have been momentous. Scientists have identified more than twenty species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans. They have revealed how early technology, language ability, and artistic endeavour all originated in Africa; and they have shown how small groups of Africans spread out from Africa in an exodus sixty thousand years ago to populate the rest of the world. We have all inherited an African past.

    After sampling myths explaining First Light, the story moves on to early philosophers' queries, then through the centuries, from Buddhist temples to Biblical scripture, when light was the soul of the divine.Battling darkness and despair, Gothic architects crafted radiant cathedrals while Dante dreamed a "heaven of pure light." Later, following Leonardo's advice, Renaissance artists learned to capture light on canvas. During the Scientific Revolution, Galileo gathered light in his telescope, Descartes measured the rainbow, and Newton used prisms to solidify the science of optics. But even after Newton, light was an enigma. Particle or wave? Did it flow through an invisible "ether"? Through the age of Edison and into the age of lasers, Light reveals how light sparked new wonders--relativity, quantum electrodynamics, fiber optics, and more.Although lasers now perform everyday miracles, light retains its eternal allure. "For the rest of my life," Einstein said, "I will reflect on what light is." Light explores and celebrates such curiosity.

    In this classic work Anne Sayre, a journalist and close friend of Franklin, puts the record straight.

    Of these, gravity may the most obvious, but it is also the most mysterious. Newton managed to predict the force of gravity but couldn't explain how it worked at a distance. Einstein picked up on the simple premise that gravity and acceleration are interchangeable to devise his mind-bending general relativity, showing how matter warps space and time. Not only did this explain how gravity worked – and how apparently simple gravitation has four separate components – but it predicted everything from black holes to gravity's effect on time. Whether it's the reality of anti-gravity or the unexpected discovery that a ball and a laser beam drop at the same rate, gravity is the force that fascinates.

    Now scientists have documented mass migrations over the Gulf of Mexico, identified the voices of migrants in the night sky, and showed how songbirds navigate using stars, polarized light, and magnetic fields. Miyoko Chu explores the intricacies underlying the ebb and flow of migration, the cycle of seasons, and the interconnectedness between distant places. Songbird Journeys pays homage to the wonder and beauty of songbirds while revealing the remarkable lives of migratory birds and the scientific quest to answer age-old questions about where songbirds go, how they get there, and what they do in the far-flung places they inhabit throughout the year.

    For the healthy but overworked majority, this might sound like an enviable condition, but for Henry, the inability to stay awake is profoundly disabling, especially as it is accompanied by mysterious collapses called cataplexy, poor night-time sleep, hallucinations and sleep paralysis.A writer and biologist, Nicholls explores the science of disordered sleep, discovering that around half of us will experience some kind of sleep dysfunction in our lives. From a CBT course to tackle insomnia to a colony of narcoleptic Dobermans, his journey takes him through the half-lit world of sleep to genuine revelations about his own life and health.Told with humour and intelligence, Sleepyhead uses personal reflections, interviews with those with sleep disorders and the people who study them, anecdotes from medical history and insights from art and literature to change the way we understand our sleeping hours.

    From the first microbes and jawless fishes that evolved into the myriad species we know today-sharks, whales, dolphins, and, of course, humans-Ellis reveals the deep evolutionary mysteries of the sea. Encyclopedic in scope and complemented by more than sixty drawings, Aquagenesis is a fascinating work that will astonish readers with the wonder, richness, and complexity of the evolution of life. "Quite simply, the best account we now have of the origins of human life." (Te Christian Science Monitor)

    They unearthed a treasure trove of Cretaceous dinosaurs and mammals, including several new species, that has already helped to reshape our understanding of the dinosaur age. In Dinosaurs of the Flaming Cliffs, team leader Michael Novacek, Provost of Science of the American Museum of Natural History and Curator of Vertebrate Paleontology, re-creates the day-to-day drama of field exploration over the past six years in the Gobi and recounts his and his colleagues' historic discoveries, reported in front-page headlines across the world. In a remarkable narrative that interweaves expedition chapters with in-depth scientific discussions on the nature and importance of the fossil record, Novacek takes us on a journey that explores the very nature of scientific inquiry and dinosaur research.

    General Ishii Shiro during World War II released hundreds of millions of infected insects across China, ultimately causing more deaths than the atomic bombs dropped on Japan. These are just two of many startling examples found in Six-legged Soldiers, a brilliant portrait of the many weirdly creative, truly frightening, and ultimately powerful ways in which insects have been used as weapons of war, terror, and torture. Beginning in prehistoric times and building toward a near and disturbing future, the reader is taken on a journey of innovation and depravity. Award-winning science writer Jeffrey A. Lockwood begins with the development of bee bombs in the ancient world and explores the role of insect-borne disease in changing the course of major battles, ranging from Napoleon's military campaigns to the trenches of World War I. He explores the horrific programs of insect warfare during World War II: airplanes dropping plague-infested fleas, facilities rearing tens of millions of hungry beetles to destroy crops, and prison camps staffed by doctors testing disease-carrying lice on inmates. The Cold War saw secret government operations involving the mass release of specially developed strains of mosquitoes on an unsuspecting American public--along with the alleged use of disease-carrying and crop-eating pests against North Korea and Cuba. Lockwood reveals how easy it would be to use of insects in warfare and terrorism today: In 1989, domestic ecoterrorists extorted government officials and wreaked economic and political havoc by threatening to release the notorious Medfly into California's crops. A remarkable story of human ingenuity--and brutality--Six-Legged Soldiers is the first comprehensive look at the use of insects as weapons of war, from ancient times to the present day.

    It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time.The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to theclassification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like D�bereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail.Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successivetheories of the electron including Bohr's quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early electronic configurations published by Bohr andothers.Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closeswith an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain such trends.

    The find quickly became known around the world as Peking Man and was acclaimed as the missing link between erect hunting apes and our Cro-Magnon ancestors. It also became a provocative piece of evidence in the roiling debate over creationism versus evolution. For Teilhard, both a scientist and man of God, the discovery also exposed a deeply personal conflict between the new science and his faith. He was commanded by his superiors to deny all scientific evidence that went against biblical teachings, and his writing and lectures were censored by the Vatican. But his curiosity and desire to find connections between scientific and spiritual truth kept him investigating man's origins. His inner struggle, and, in turn, his public rebuke by the Catholic Church personified one of the central debates of our time: How to reconcile an individual's commitment to science and his commitment to his faith. In "The Jesuit and the Skull," bestselling author Amir D. Aczel vividly recounts the discovery of Peking Man and its repercussions, and how Teilhard de Chardin's scientific work helped to open the eyes of the world to new theories of humanity's origins that alarmed the traditionalists within the Church. A deft mix of narrative history and a poignant personal story, The Jesuit and the Skull brings fresh insight to a debate that still rages today.
