Leonardo da Vinci’s notebooks are mind-boggling evidence of a 15th-century scientific genius standing at the edge of the modern world, basing his ideas on observation and experimentation. This book will change children’s ideas of who Leonardo was and what it means to be a scientist.

From world-renowned historian and philosopher Yuval Noah Harari, the New York Times bestselling author of Sapiens, comes an exciting, brand-new audiobook for middle-grade listeners that looks at the early history of humankind.

Did you know that it’s believed Galileo was scolded by the Roman Inquisition for sassing his mom? That Isaac Newton loved to examine soap bubbles? That Albert Einstein loved to collect joke books, and that geneticist Barbara McClintock wore a Groucho Marx disguise in public? With juicy tidbits about everything from favorite foods to first loves, the subjects of Kathleen Krull and Kathryn Hewitt’s Lives of the Scientists: Experiments, Explosions (and What the Neighbors Thought) are revealed as creative, bold, sometimes eccentric - and anything but dull.

As a young boy, Charles Darwin hated school and was often scolded for conducting “useless” experiments. Yet his passion for the natural world was so strong that he suffered through terrible seasickness during his five-year voyage aboard The Beagle. Darwin collected new creatures from the coasts of Africa, South America, and the Galapagos Islands, and expanded his groundbreaking ideas that would change people's understanding of the natural world. This audiobook will make Darwin and his theory of evolution an exciting discovery for every young listener.

From the time she was a girl, Jane Goodall dreamed of a life spent working with animals. Finally she had her wish. When she was 26 years old, she ventured into the forests of Africa to observe chimpanzees in the wild. On her expeditions she braved the dangers with leopards and lions in the African bush. And she got to know an amazing group of wild chimpanzees - intelligent animals whose lives, in work and play and family relationships, bear a surprising resemblance to our own.

In December of 1938, a chemist in a German laboratory made a shocking discovery: When placed next to radioactive material, a Uranium atom split in two. That simple discovery launched a scientific race that spanned three continents. In Great Britain and the United States, Soviet spies worked their way into the scientific community; in Norway, a commando force slipped behind enemy lines to attack German heavy-water manufacturing; and deep in the desert, one brilliant group of scientists was hidden away at a remote site at Los Alamos.

If there is one belief that has united the left and the right, psychologists and philosophers, ancient thinkers and modern ones, it is the tacit assumption that humans are bad. It's a notion that drives newspaper headlines and guides the laws that shape our lives. From Machiavelli to Hobbes, Freud to Pinker, the roots of this belief have sunk deep into Western thought. Human beings, we're taught, are by nature selfish and governed primarily by self-interest.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 100 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto.

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. When his specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake, many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation.

When young Joseph Banks stepped onto a Tahitian beach in 1769, he hoped to discover Paradise. Inspired by the scientific ferment sweeping through Britain, the botanist had sailed with Captain Cook in search of new worlds. Other voyages of discovery—astronomical, chemical, poetical, philosophical—swiftly follow in Richard Holmes's thrilling evocation of the second scientific revolution.

In 1913, an unschooled young Indian clerk wrote a letter to G. H. Hardy, begging that preeminent English mathematician's opinion on several ideas he had about numbers. Hardy, realizing the letter was the work of a genius, arranged for Srinivasa Ramanujan to come to England. Thus began one of the most remarkable collaborations ever chronicled.

Edward O. Wilson has distilled sixty years of teaching into a book for students, young and old. Reflecting on his coming-of-age in the South as a Boy Scout and a lover of ants and butterflies, Wilson threads these twenty-one letters, each richly illustrated, with autobiographical anecdotes that illuminate his career - both his successes and his failures - and his motivations for becoming a biologist.

For decades Richard Dawkins has been the world's most brilliant scientific communicator, consistently illuminating the wonders of nature and attacking faulty logic. Science in the Soul brings together 42 essays, polemics, and paeans - culled from personal papers, newspapers, lectures, and online salons - all written with Dawkins' characteristic erudition, remorseless wit, and unjaded awe of the natural world.

In December 1929, in a cave near Peking, a group of anthropologists and archaeologists that included a young French Jesuit priest named Pierre Teilhard de Chardin uncovered a prehuman skull. 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.
