    This book is an extraordinary reminder of what can be achieved with inner belief and an indefatigable spirit.’ JAY SHETTY'Siya's story is well documented, and I am so impressed by the way he conducts himself. As the captain of his team and as a statesman he is measured and thoughtful. He is a leader in every way. An inspiration to a dynamic South African nation.' EDDIE JONES‘Few people embody the tenacity of what the New South Africa stands for, like Siya does. His story mirrors the nations’; in its trials and tribulations and also in it’s triumph against all odds. This is a real life heroes journey.’ TREVOR NOAH‘There is no doubt Siya has made a significant impact on World rugby, especially within South African rugby. [He] is passionate about changing people's lives for the better and uses his position and status to do that.’ MARO ITOJE‘Brilliant’ THE TIMES‘Moving’ THE GUARDIANHis truth. His story. In his words.There have been many comments made and books written about Siya Kolisi, captain of the Springboks, and the first black man to lead his country in over 128 years of South African rugby. But now, for the very first time, Siya Kolisi shares his story in an extraordinarily intimate memoir, charting his journey from being born into the impoverished Zwide township, to leading his proud nation to an astonishing victory at the Rugby World Cup in 2019. However, Rise is not simply a chronology of matches played and games won; it is an exploration of a man’s race and his faith, a masterclass in attaining a positive mindset, and an inspirational reminder that it is possible to defy the odds, no matter how they are stacked against you. In 2020, partly in response to the pandemic, Siya and his wife, Rachel, launched The Kolisi Foundation, providing personal protective equipment to healthcare workers and delivering food parcels throughout South Africa. The title Rise is inspired by Siya’s mother – Phakama – which translates to the book’s name, as well as a celebration of his Xhosa heritage.

    It was shortly before 19h00 when Don Steenkamp jumped out of the vehicle and ran into the station’s charge office, covered in blood, to announce that his parents and sister had been brutally shot and killed on the family farm, Naauwhoek. Although the killings were initially thought to be just another farm attack, months later a sixteen-year-old youth was arrested for the murders, setting in motion a chain of events that would grip South Africa, and divide the people of Griekwastad.Based on interviews with all the role-players, including the investigating officers on the case, the forensic and ballistic experts, and family and friends of the deceased, this is the riveting account of what really happened on Naauwhoek farm on that fateful day, as told by the reporter who followed the case from day one…

    Because of those lessons in observation, Stott now carries his binoculars and camera with him everywhere he travels. Of the 9,000 different bird species in the world, Stott estimates he has seen about 2,500! In this unique and intriguing book he takes seriously Jesus' exhortation in the Sermon on the Mount, "Behold the fowls of the air" (Matt. 6:26 KJV). He reveals lessons on faith from the feeding of ravens, on repentance from the migration of storks, on freedom from the flight of the eagle, on joy from the song of the lark, and more. The Birds Our Teachers is lavishly illustrated with full-color photographs taken by the author in his travels around the world. Stott humorously calls his work "an introduction to the science of orni-theology," for he combines information about birds with biblical truths and personal anecdotes in a way that will fascinate bird-lovers and Bible readers everywhere.

    A story of defiance and determination by a controversial scientist, this is Lee Berger's own take on finding Homo naledi, an all-new species on the human family tree and one of the greatest discoveries of the 21st century.In 2013, Berger, a National Geographic Explorer-in-Residence, caught wind of a cache of bones in a hard-to-reach underground cave in South Africa. He put out a call around the world for petite collaborators--men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of "underground astronauts," Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known prehominids like Lucy, the famous Australopithecus, with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species, and they called it Homo naledi.The cave quickly proved to be the richest primitive hominid site ever discovered, full of implications that shake the very foundation of how we define what makes us human. Did this species come before, during, or after the emergence of Homo sapiens on our evolutionary tree? How did the cave come to contain nothing but the remains of these individuals? Did they bury their dead? If so, they must have had a level of self-knowledge, including an awareness of death. And yet those are the very characteristics used to define what makes us human. Did an equally advanced species inhabit Earth with us, or before us? Berger does not hesitate to address all these questions.Berger is a charming and controversial figure, and some colleagues question his interpretation of this and other finds. But in these pages, this charismatic and visionary paleontologist counters their arguments and tells his personal story: a rich and readable narrative about science, exploration, and what it means to be human.

    Immediately, he winced with pain and yanked out his hand. A tiny black-and-white banded snake, less than ten inches long, was dangling limply from his middle finger, its fangs still sunk into his flesh. In the fall of 2001, deep in the jungle of Burma, a team of scientists is searching for rare snakes. They are led by Dr. Joe Slowinski, at forty already one of the most brilliant biologists of our time. It is the most ambitious scientific expedition ever mounted into this remote region, venturing into the foothills of the Himalayas. The bold undertaking is brought to a dramatic halt by the bite of the many-banded krait, the deadliest serpent in Asia. In the moment he pulled his hand from the specimen bag and saw the krait, Joe knew that his life was in grave and imminent peril. Thus began one of the most remarkable wilderness rescue attempts of modern times, as Joe's teammates kept him alive for thirty hours by mouth-to-mouth respiration, waiting for a rescue that never came. A daredevil obsessed with venomous snakes since his youth, Slowinski was a modern-day adventurer who rose quickly to the top of his field, discovering many previously unidentified snake species in his brief yet exhilarating career. The Snake Charmer is at once brilliant biography and exotic travel literature, blended with an accessible introduction to the bizarre, fascinating-and sometimes controversial-world of snake science. The narrative transports the reader into primeval wilderness, from the Everglades to Peru to Burma, in search of rattlesnakes and boa constrictors, kraits and cobras. Joe Slowinski's career was fast and exciting, his tragic final expedition a pulse-pounding struggle between man and nature. In The Snake Charmer, renowned journalist and author Jamie James captures the life and death of this charismatic, endlessly fascinating man. Exhaustively researched in interviews with Slowinski's colleagues and family, and the author's own trek into the wilds of Burma, this is narrative nonfiction in the tradition of Into the Wild and The Perfect Storm.

    Their numbers are in freefall, dropping by nearly 70 percent in the last sixty years, a billion fewer now than in 1950. Extinction stalks the ocean, and there is a danger that the hundred-million-year-old cries of a seabird colony, rolling around in the bays and headlands of high latitudes, will this century become but a memory.

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.

    Fossey's extraordinary efforts to ensure the future of the rain forest and its remaining mountain gorillas are captured in her own words and in candid photographs of this fascinating endangered species. As only she could, Fossey combined her personal adventure story with groundbreaking scientific reporting in an unforgettable portrait of one of our closest primate relatives. Although Fossey's work ended tragically in her murder, Gorillas in the Mist remains an invaluable testament to one of the longest-running field studies of primates and reveals her undying passion for her subject.

    In this amusing memoir, he recounts his quest, including how he spent all of his inheritance from the untimely death of his parents to make his dream a reality. Populated by unusual characters and interesting species of birds, this part confessional–part travelogue for both bird nerds and the general population follows the author as he works out what it means to be normal despite his unusually avid compulsion toward twitching.

    In an attempt to overcome his phobia, he undertakes a voyage to Australia, Africa, India, and America in search of the most notorious and deadly species, and to meet the people who live among them. He encounters a Kenyan snake man, whose entire life seems like a preparation for a bite from the terrible black mamba; witch doctors, who use snakes as instruments of vengeance; frightened Australian convicts; and even a preacher in the Deep South, who uses his church's rattlesnakes to try to murder his wife. Along the way Seal recounts amazing scientific snake lore, legends, and historical facts. An erudite but highly entertaining narrative in the English travel-writing tradition, and a finalist for the Thomas Cook Travel Book Award, The Snakebite Survivors' Club tells a funny, gruesomely fascinating account of the world of snakes and the people they repel, mesmerize, and sometimes kill.

    It floats like a jewel in the inky black void. The reflection of the suns light from the vast expanse of water covering its surface creates its gem-like blue colour. In the entire solar system Earth is the only planet that has water in its liquid form in such quantities. Scientists have calculated that 70% of our planet is covered by water; small wonder then that humans have always been so fascinated by the oceans and what lies beneath. Today while we still have so much more of the ocean realm to uncover we have discovered enough to know that beneath the waves lies a vast treasure-trove of rich and diverse life. The Blue Planet leads us on a voyage of exploration from the coasts, the very edges of the oceans, to the deep where weird and monstrous fish lurk in a world of perpetual darkness. Along the way we meet a host of wonderful creatures from tiny copepods to majestic blue whales, from the grotesque hairy anglerfish, to the amazing tripod fish that stands on 3 delicate legs waiting to snap up unsuspecting prey. With a foreword by David Attenborough and 400 colour photos The Blue Planet is the first complete and comprehensive portrait of the whole ocean system.
