“An engaging voyage into some of the great mysteries and wonders of our world." --Alan Lightman, author of Einstein’s Dream and The Accidental Universe “No one is better at making the recondite accessible and exciting.” —Bill Bryson Brain Pickings and Kirkus Best Science Book of the Year Every week seems to throw up a new discovery, shaking the foundations of what we know. But are there questions we will never be able to answer—mysteries that lie beyond the predictive powers of science? In this captivating exploration of our most tantalizing unknowns, Marcus du Sautoy invites us to consider the problems in cosmology, quantum physics, mathematics, and neuroscience that continue to bedevil scientists and creative thinkers who are at the forefront of their fields. At once exhilarating, mind-bending, and compulsively readable, The Great Unknown challenges us to consider big questions—about the nature of consciousness, what came before the big bang, and what lies beyond our horizons—while taking us on a virtuoso tour of the great breakthroughs of the past and celebrating the men and women who dared to tackle the seemingly impossible and had the imagination to come up with new ways of seeing the world.

What is your name? Where did you come from? And where are you going? In this immersive novel set in 1840s Britain and France, these questions probe at the essence of what it means to be human. A wet nurse in a lively Scottish household goes by an assumed name, but longs to know the identity of her father. A quarryman furtively extricates a remarkable fossil from an island off the Northumberland coast and promptly smuggles it abroad to Paris. A sensational best-selling book that shatters cherished notions about the universe and everything in it triggers widespread argument and speculation—but its author’s name is a well-guarded secret. Another book, roundly ignored, neatly sets forth in an obscure appendix the principle that will become the centerpiece of Charles Darwin’s On the Origin of Species. All these threads—some historical, others fictional—converge and illuminate one another in unexpected ways in the climactic revelations of this brilliant story.

Drawing on rarely examined diaries and journals, Down the Great Unknown is the first book to tell the full, dramatic story of the Powell expedition. On May 24, 1869 a one-armed Civil War veteran, John Wesley Powell and a ragtag band of nine mountain men embarked on the last great quest in the American West. The Grand Canyon, not explored before, was as mysterious as Atlantis—and as perilous. The ten men set out from Green River Station, Wyoming Territory down the Colorado in four wooden rowboats. Ninety-nine days later, six half-starved wretches came ashore near Callville, Arizona. Lewis and Clark opened the West in 1803, six decades later Powell and his scruffy band aimed to resolve the West’s last mystery. A brilliant narrative, a thrilling journey, a cast of memorable heroes—all these mark Down the Great Unknown, the true story of the last epic adventure on American soil.

In TheGreat Unknown, award-winning historian and journalist Greg Robinson offers a fascinating and compulsively readable collection of biographical portraits of extraordinary but unheralded figures in Japanese American history: men and women who made remarkable contributions in the arts, literature, law, sports, and other fields. Recovering and celebrating the stories of noteworthy Issei and Nisei and of their supporters, TheGreat Unknown provides powerful evidence of the diverse experiences and substantial cultural, political, and intellectual contributions of Nikkei throughout the country and over multiple decades. What is more, The Great Unknown reshapes our understanding of the Asian American experience. By focusing attention on exceptional figures who deviated from social norms, Robinson subverts stereotypes of ethnic Japanese and other Asians as conformist or colorless. The collection also highlights a set of recurring themes absent from conventional histories—including the lives of Japanese Americans outside the West Coast, the role of women in shaping community life, encounters between Japanese American and African American communities during the struggle for civil rights, and the evolving status of queer community members.

Geoff Spearpoint is a legend among New Zealand¿s tramping and mountaineering community. For over 50 years he has been undertaking many long, adventurous trips in the Southern Alps every year, decade after decade. These trips, usually a mix of both tramping and mountaineering, have made Spearpoint New Zealand¿s foremost exponent of what is best described as trans-alpine tramping. In the Great Unknown he collects together personal accounts of his favourite trips into 15 geographical areas, ranging from Kahurangi in the north to the Fiordland in the south. Illustrated with his stunning photography, and with maps from Geographx, this will be a completely unique book that trampers and mountaineers will cherish, for it explores an important element of New Zealand tramping that goes to the heart of how we define our relationship with backcountry.

A lively chronicle of his enigmatic life.

Every time we download music, take a flight across the Atlantic or talk on our cell phones, we are relying on great mathematical inventions. In The Number Mysteries, one of our generation's foremost mathematicians Marcus du Sautoy offers a playful and accessible examination of numbers and how, despite efforts of the greatest minds, the most fundamental puzzles of nature remain unsolved. Du Sautoy tells about the quest to predict the future—from the flight of asteroids to an impending storm, from bending a ball like Beckham to forecasting population growth. He brings to life the beauty behind five mathematical puzzles that have contributed to our understanding of the world around us and have helped develop the technology to cope with it. With loads of games to play and puzzles to solve, this is a math book for everyone.
