Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves. Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes "backwards" sometimes; how to turn the tide in the fight against AIDS.

On October 4, 1957, the Soviet Union launched Sputnik I, and the space race was born. Desperate to beat the Russians into space, NASA put together a crew of the nation's most daring test pilots: the seven men who were to lead America to the moon. The first into space was Alan Shepard; the last was Deke Slayton, whose irregular heartbeat kept him grounded until 1975. They spent the 1960s at the forefront of NASA's effort to conquer space, and Moon Shot is their inside account of what many call the 20th century's greatest feat - landing humans on another world.

"You seriously mean to tell me that the ship is doomed?" asked Frank Worsley, commander of the Endurance, stuck impassably in Antarctic ice packs. "What the ice gets," replied Sir Ernest Shackleton, the expedition's unflappable leader, "the ice keeps." It did not, however, get the ship's twenty-five crew members, all of whom survived an eight-hundred-mile voyage across sea, land, and ice to South Georgia, the nearest inhabited island.

When Columbus triumphantly returned from America to Spain in 1493, his discoveries inflamed an already smoldering conflict between Spain's renowned monarchs, Ferdinand and Isabella, and Portugal's João II. Which nation was to control the world's oceans? To quell the argument, Pope Alexander VI issued a proclamation laying the foundation for the Treaty of Tordesillas of 1494, an edict that created an imaginary line in the Atlantic Ocean dividing the entire known (and unknown) world between Spain and Portugal.

Between 1539 and 1542, the Spanish explorer Hernando de Soto led a small army on an expedition of almost four thousand miles across Southeastern America. De Soto's path had been one of history's most intriguing mysteries until the publication of Knights of Spain, Warriors of the Sun. Using a new route reconstruction, anthropologist Charles Hudson maps the story of the de Soto expedition, tying the route to a number of specific archaeological sites.

Until the early 1870s, very little was known about the creatures lurking in the depths of our oceans. The first systematic investigation into life in our oceans was made during the circumnavigation of the HMS Challenger. Scientists credit this voyage as the beginning of modern oceanography. In this book, Graham Bell takes listeners through the voyage station by station, following the progress of the expedition and introducing some of the new and strange animals that were hauled up from the depths of the ocean and seen by human eyes for the first time.

Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes.

In 1804, John Colter set out with Meriwether Lewis and William Clark on the first US expedition to traverse the North American continent. During the 28-month ordeal, Colter served as a hunter and scout, and honed his survival skills on the western frontier. But when the journey was over, Colter stayed behind. He spent two more years trekking alone through dangerous and unfamiliar territory, charting some of the West's most treasured landmarks.

Using an infamous deception about a fake mountain range in British Columbia as her jumping-off point, Katie Ives explores the lure of blank spaces on the map and the value of the imagination. In Imaginary Peaks she details the cartographical mystery of the Riesenstein Hoax within the larger context of climbing history and the seemingly endless quest for newly discovered peaks and claims of first ascents. Imaginary Peaks is an evocative, thought-provoking tale, immersed in the literature of exploration, study of maps, and basic human desire.

Published to coincide with the centenary of the first expeditions to reach the South Pole, An Empire of Ice presents a fascinating new take on Antarctic exploration. Retold with added information, it's the first book to place the famed voyages of Norwegian explorer Roald Amundsen, his British rivals Robert Scott and Ernest Shackleton, and others in a larger scientific, social, and geopolitical context.

In AD 793 Norse warriors struck the English isle of Lindisfarne and laid waste to it. Wave after wave of Norse "sea wolves" followed in search of plunder, land, or a glorious death in battle. Much of the British Isles fell before their swords, and the continental capitals of Paris and Aachen were sacked in turn. Turning east, they swept down the uncharted rivers of central Europe, captured Kiev, and clashed with mighty Constantinople, the capital of the Byzantine Empire.

In The Normans, Lars Brownworth follows their story, from the first shock of a Viking raid on an Irish monastery to the exile of the last Norman Prince of Antioch. In the process, he brings to vivid life the Norman tapestry's rich cast of characters: figures like Rollo the Walker, William Iron-Arm, Tancred the Monkey King, and Robert Guiscard. The Normans presents a fascinating glimpse of a time when a group of restless adventurers had the world at their fingertips.

In the early years of the 18th century, a band of French scientists set off on a daring, decade-long expedition to South America in a race to measure the precise shape of the earth. Like Lewis and Clark's exploration of the American West, their incredible mission revealed the mysteries of a little-known continent to a world hungry for discovery. Scaling 16,000-foot mountains in the Peruvian Andes, and braving jaguars, pumas, insects, and vampire bats in the jungle, the scientists barely completed their mission.

Throughout Lewis and Clark for Dummies, you find out about Jefferson's western exploration from his earliest efforts to see the Corps assembled through the aftermath for the explorers, the tribes, and the United States. But the focus of Lewis & Clark for Dummies is on the period between Jefferson's confidential letter to Congress requesting dollars to mount a western exploration (January 18,1803) and the expedition's triumphant (and improbable) return to St. Louis (September 23, 1806): 42 months that changed the world.

In 1957 the Soviet Union sent Sputnik, the first man-made satellite, into space. America took up the challenge to explore the next frontier. A dozen years, and 25 billion dollars later, the mission of Apollo 11 would yield man's finest hour. For that was the first time man's foot left prints on another heavenly body. And that was only the beginning. Apollo 11 is the incredible story of how a nation forged the technology during the turbulent 1960s to slip humanity from the bonds of its native planet. This inside look remembers those who made the great enterprise succeed.

In the tradition of Simon Winchester and Dava Sobel, The Riddle of the Labyrinth: The Quest to Crack an Ancient Code tells one of the most intriguing stories in the history of language, masterfully blending history, linguistics, and cryptology with an elegantly wrought narrative. When famed archaeologist Arthur Evans unearthed the ruins of a sophisticated Bronze Age civilization that flowered on Crete 1,000 years before Greece's Classical Age, he discovered a cache of ancient tablets, Europe's earliest written records.

As war clouds darkened over Europe in 1914, a party led by Sir Ernest Shackleton set out to make the first crossing of the entire Antarctic continent via the Pole. But their initial optimism was short-lived as ice floes closed around their ship, gradually crushing it and marooning twenty-eight men on the polar ice. Alone in the world's most unforgiving environment, Shackleton and his team began a brutal quest for survival.

The North Pole, originally published in 1910, makes available Robert E. Peary's own account of his expedition in the Arctic. It provides hotly contested evidence that remains an indispensable key in deciding who deserved the coveted title "Discoverer of the North Pole". It is also a gripping adventure story that is impossible to put down.

What accounts for the rise of the state, the creation of the first global system, and the dominance of the West? The conventional answer asserts that superior technology, tactics, and institutions forged by Darwinian military competition gave Europeans a decisive advantage in war from 1500 onward. Empires of the Weak argues that Europeans had no general military superiority in the early modern era. Sharman shows instead that European expansion is better explained by deference to strong Asian and African polities, disease in the Americas, and maritime supremacy earned by default.

Unsettled tells the story of two hundred Highlanders who flee the Scottish Clearances in 1813 to establish a settlement on the Red River in what eventually became Winnipeg. They are sponsored by the Earl of Selkirk, a man who has never been west of Montreal. Families who have never left their Highland crofts take an epic journey over ocean, up wild rivers, and through boundless wilderness, surviving disease and brutal winter only to face the determined opposition of fur barons who want no sodbusters threatening their trade and are prepared to stop at nothing to destroy their dream.
