Keenly aware that the course of the nation's destiny lay westward—and that a "Voyage of Discovery" would be necessary to determine the nature of the frontier—President Thomas Jefferson commissioned Meriwether Lewis to lead an expedition from the Missouri River to the northern Pacific coast and back. From 1804 to 1806, accompanied by co-captain William Clark, the Shoshone guide Sacajawea, and thirty-two men, Lewis mapped rivers, traced the principal waterways to the sea, and established the American claim to the territories of Idaho, Washington, and Oregon. Together the captains kept this journal: a richly detailed record of the flora and fauna they sighted, the native tribes they encountered, and the awe-inspiring landscape they traversed, from their base camp near present-day St. Louis to the mouth of the Columbia River, that has become an incomparable contribution to the literature of exploration and the writing of natural history.

    The presentation stresses analytical methods, concrete examples, and geometric intuition. A unique feature of the book is its emphasis on applications. These include mechanical vibrations, lasers, biological rhythms, superconducting circuits, insect outbreaks, chemical oscillators, genetic control systems, chaotic waterwheels, and even a technique for using chaos to send secret messages. In each case, the scientific background is explained at an elementary level and closely integrated with mathematical theory.About the Author:Steven Strogatz is in the Center for Applied Mathematics and the Department of Theoretical and Applied Mathematics at Cornell University. Since receiving his Ph.D. from Harvard university in 1986, Professor Strogatz has been honored with several awards, including the E.M. Baker Award for Excellence, the highest teaching award given by MIT.

    The fantastic journey began in 1977, before the first episode of Cosmos aired. The mission was planned as a grand tour beyond the moon; beyond Mars, Jupiter, and Saturn; and maybe even into interstellar space. The fact that it actually happened makes this humanity's greatest space mission.In The Interstellar Age, award-winning planetary scientist Jim Bell reveals what drove and continues to drive the members of this extraordinary team, including Ed Stone, Voyager's chief scientist and the one-time head of NASA's Jet Propulsion Lab; Charley Kohlhase, an orbital dynamics engineer who helped to design many of the critical slingshot maneuvers around planets that enabled the Voyagers to travel so far; and the geologist whose Earth-bound experience would prove of little help in interpreting the strange new landscapes revealed in the Voyagers' astoundingly clear images of moons and planets.Speeding through space at a mind-bending eleven miles a second, Voyager 1 is now beyond our solar system's planets. It carries with it artifacts of human civilization. By the time Voyager passes its first star in about 40,000 years, the gold record on the spacecraft, containing various music and images including Chuck Berry's "Johnny B. Goode," will still be playable.

    That collaboration would mark the dawn of modern science . . . and end in murder.Johannes Kepler changed forever our understanding of the universe with his three laws of planetary motion. He demolished the ancient model of planets moving in circular orbits and laid the foundation for the universal law of gravitation, setting physics on the course of revelation it follows to this day. Kepler was one of the greatest astronomers of all time. Yet if it hadn't been for the now lesser-known Tycho Brahe, the man for whom Kepler apprenticed, Kepler would be a mere footnote in today's science books. Brahe was the Imperial Mathematician at the court of the Holy Roman Emperor in Prague and the most famous astronomer of his era. He was one of the first great systematic empirical scientists and one of the earliest founders of the modern scientific method. His forty years of planetary observations—an unparalleled treasure of empirical data—contained the key to Kepler's historic breakthrough. But those observations would become available to Kepler only after Brahe's death. This groundbreaking history portrays the turbulent collaboration between these two astronomers at the turn of the seventeenth century and their shattering discoveries that would mark the transition from medieval to modern science. But that is only half the story. Based on recent forensic evidence (analyzed here for the first time) and original research into medieval and Renaissance alchemy—all buttressed by in-depth interviews with leading historians, scientists, and medical specialists—the authors have put together shocking and compelling evidence that Tycho Brahe did not die of natural causes, as has been believed for four hundred years. He was systematically poisoned—most likely by his assistant, Johannes Kepler. An epic tale of murder and scientific discovery, Heavenly Intrigue reveals the dark side of one of history’s most brilliant minds and tells the story of court politics, personal intrigue, and superstition that surrounded the protean invention of two great astronomers and their quest to find truth and beauty in the heavens above.

    This book reveals the most exhilarating oddities from Professor Stewart's legendary cabinet.Inside, you will find hidden gems of logic, geometry, and probability-like how to extract a cherry from a cocktail glass (harder than you think), a pop-up dodecahedron, and the real reason why you can't divide anything by zero. Scattered among these are keys to Fermat's last theorem, the Poincaréonjecture, chaos theory, and the P=NP problem (you'll win a million dollars if you solve it). You never know what enigmas you'll find in the Stewart cabinet, but they're sure to be clever, mind-expanding, and delightfully fun.

    An ancient curse. A stunning medical mystery. And a pioneering journey into the unknown heart of the world's densest jungle.Since the days of conquistador Hernán Cortés, rumors have circulated about a lost city of immense wealth hidden somewhere in the Honduran interior, called the White City or the Lost City of the Monkey God. Indigenous tribes speak of ancestors who fled there to escape the Spanish invaders, and they warn that anyone who enters this sacred city will fall ill and die. In 1940, swashbuckling journalist Theodore Morde returned from the rainforest with hundreds of artifacts and an electrifying story of having found the Lost City of the Monkey God-but then committed suicide without revealing its location.Three quarters of a century later, author Doug Preston joined a team of scientists on a groundbreaking new quest. In 2012 he climbed aboard a rickety, single-engine plane carrying the machine that would change everything: lidar, a highly advanced, classified technology that could map the terrain under the densest rainforest canopy. In an unexplored valley ringed by steep mountains, that flight revealed the unmistakable image of a sprawling metropolis, tantalizing evidence of not just an undiscovered city but an enigmatic, lost civilization.Venturing into this raw, treacherous, but breathtakingly beautiful wilderness to confirm the discovery, Preston and the team battled torrential rains, quickmud, disease-carrying insects, jaguars, and deadly snakes. But it wasn't until they returned that tragedy struck: Preston and others found they had contracted in the ruins a horrifying, sometimes lethal-and incurable-disease.

    At the end of the nineteenth century, serial murderer Joseph Vacher, known and feared as "The Killer of Little Shepherds," terrorized the French countryside. He eluded authorities for years--until he ran up against prosecutor Emile Fourquet and Dr. Alexandre Lacassagne, the era's most renowned criminologist. The two men--intelligent and bold--typified the Belle Epoque, a period of immense scientific achievement and fascination with science's promise to reveal the secrets of the human condition. With high drama and stunning detail, Douglas Starr revisits Vacher's infamous crime wave, interweaving the story of how Lacassagne and his colleagues were developing forensic science as we know it. We see one of the earliest uses of criminal profiling, as Fourquet painstakingly collects eyewitness accounts and constructs a map of Vacher's crimes. We follow the tense and exciting events leading to the murderer's arrest. And we witness the twists and turns of the trial, celebrated in its day. In an attempt to disprove Vacher's defense by reason of insanity, Fourquet recruits Lacassagne, who in the previous decades had revolutionized criminal science by refining the use of blood-spatter evidence, systematizing the autopsy, and doing groundbreaking research in psychology. Lacassagne's efforts lead to a gripping courtroom denouement. "The Killer of Little Shepherds" is an important contribution to the history of criminal justice, impressively researched and thrillingly told.

    “A marvelously readable and level-headed explanation of basic science and how it relates to the issues.” —John Tierney, New York TimesThis is “must-have” information for all presidents—and citizens—of the twenty-first century: Is Iran’s nascent nuclear capability a genuine threat to the West? Are biochemical weapons likely to be developed by terrorists? Are there viable alternatives to fossil fuels that should be nurtured and supported by the government? Should nuclear power be encouraged? Can global warming be stopped?

    

    Randall Fuller takes us back to one of those turning points, in 1860, with the story of the influence of Charles Darwin's just-published On the Origin of Species on five American intellectuals, including Bronson Alcott, Henry David Thoreau, the child welfare reformer Charles Loring Brace, and the abolitionist Franklin Sanborn.Each of these figures seized on the book's assertion of a common ancestry for all creatures as a powerful argument against slavery, one that helped provide scientific credibility to the cause of abolition. Darwin's depiction of constant struggle and endless competition described America on the brink of civil war. But some had difficulty aligning the new theory to their religious convictions and their faith in a higher power. Thoreau, perhaps the most profoundly affected all, absorbed Darwin's views into his mysterious final work on species migration and the interconnectedness of all living things.Creating a rich tableau of nineteenth-century American intellectual culture, as well as providing a fascinating biography of perhaps the single most important idea of that time, The Book That Changed America is also an account of issues and concerns still with us today, including racism and the enduring conflict between science and religion.

    Robert Oppenheimer rode out his political persecution in the Director's mansion. It is the Institute for Advanced Study in Princeton, New Jersey; at one time or another, home to fourteen Nobel laureates, most of the great physicists and mathematicians of the modern era, and two of the most exciting developments in twentieth-century science—cellular automata and superstrings.Who Got Einstein's Office? tells for the first time the story of this secretive institution and of its fascinating personalities.

    But this attitude is a relatively recent development in the sweep of history. In The Pun Also Rises, John Pollack — a former Presidential Speechwriter for Bill Clinton, and winner of the world pun championship — explains how punning revolutionized language and made possible the rise of modern civilization. Integrating evidence from history, pop culture, literature, comedy, science, business and everyday life, this book will make readers reconsider everything they think they know about puns.

    This was the world of medicine when Thomas Dent Mütter began his trailblazing career as a plastic surgeon in Philadelphia during the middle of the nineteenth century.Although he died at just forty-eight, Mütter was an audacious medical innovator who pioneered the use of ether as anesthesia, the sterilization of surgical tools, and a compassion-based vision for helping the severely deformed, which clashed spectacularly with the sentiments of his time.   Brilliant, outspoken, and brazenly handsome, Mütter was flamboyant in every aspect of his life. He wore pink silk suits to perform surgery, added an umlaut to his last name just because he could, and amassed an immense collection of medical oddities that would later form the basis of Philadelphia’s Mütter Museum. Cristin O’Keefe Aptowicz chronicles how Mütter’s efforts helped establish Philadelphia as a global mecca for medical innovation—despite intense resistance from his numerous rivals.

    But soon, Earth's isolation could come to an end. Over the past two decades, astronomers have discovered thousands of planets orbiting other stars. Some of these exoplanets may be mirror images of our own world. And more are being found all the time.Yet as the pace of discovery quickens, an answer to the universe's greatest riddle still remains just out of reach: Is the great silence and emptiness of the cosmos a sign that we and our world are somehow singular, special, and profoundly alone, or does it just mean that we’re looking for life in all the wrong places? As star-gazing scientists come closer to learning the truth, their insights are proving ever more crucial to understanding life’s intricate mysteries and possibilities right here on Earth.Science journalist Lee Billings explores the past and future of the "exoplanet boom" through in-depth reporting and interviews with the astronomers andplanetary scientists at its forefront. He recounts the stories behind their world-changing discoveries and captures the pivotal moments that drove them forward in their historic search for the first habitable planets beyond our solar system. Billings brings readers close to a wide range of fascinating characters, such as:FRANK DRAKE, a pioneer who has used the world’s greatest radio telescopes to conduct the first searches for extraterrestrial intelligence and to transmit a message to the stars so powerful that it briefly outshone our Sun.JIM KASTING, a mild-mannered former NASA scientist whose research into the Earth’s atmosphere and climate reveals the deepest foundations of life on our planet, foretells the end of life on Earth in the distant future, and guides the planet hunters in their search for alien life.SARA SEAGER, a visionary and iron-willed MIT professor who dreams of escaping the solar system and building the giant space telescopes required to discover and study life-bearing planets around hundreds of the Sun’s neighboring stars.Through these and other captivating tales, Billings traces the triumphs, tragedies, and betrayals of the extraordinary men and women seeking life among the stars. In spite of insufficient funding, clashing opinions, and the failings of some of our world’s most prominent and powerful scientific organizations, these planet hunters will not rest until they find the meaning of life in the infinite depths of space. Billings emphasizes that the heroic quest for other Earth-like planets is not only a scientific pursuit, but also a reflection of our own culture’s timeless hopes and fears.

    It was a time of backward-seeming notions, when almost everyone still accepted the biblical account of creation as the literal truth and authoritarianism as the most natural and viable social order. But by the time both men died, the world had changed: ordinary people understood that life on earth was a story of continuous evolution, and the Civil War had proved that a democracy could fight for principles and endure. And with these signal insights much else had changed besides. Together, Darwin and Lincoln had become midwives to the spirit of a new world, a new kind of hope and faith.""Searching for the men behind the icons of emancipation and evolution, Adam Gopnik shows us, in this captivating double life, Lincoln and Darwin as they really were: family men and social climbers; ambitious manipulators and courageous adventurers; the living husband, father, son, and student behind each myth. How do we reconcile Lincoln, the supremely good man we know, with the hardened commander who wittingly sent tens of thousands of young soldiers to certain death? Why did the relentlessly rational Darwin delay publishing his "Great Idea" for almost twenty years? How did inconsolable grief at the loss of a beloved child change each man? And what comfort could either find - for himself or for a society now possessed of a sadder, if wiser, understanding of our existence? Such human questions and their answers are the stuff of this book."Above all, we see Lincoln and Darwin as thinkers and writers - as makers and witnesses of the great change in thought that marks truly modern times: a hundred years after the Enlightenment, the old rule of faith and fear finally yielding to one of reason, argument, and observation not merely as intellectual ideals but as a way of life; the judgment of divinity at last submitting to the verdicts of history and time. Lincoln considering human history, Darwin reflecting on deep time - both reshaped our understanding of what life is and how it attains meaning. And they invented a new language to express that understanding.Angels and Ages is an original and personal account of the creation of the liberal voice - of the way we live now and the way we talk at home and in public. Showing that literary eloquence is essential to liberal civilization, Adam Gopnik reveals why our heroes should be possessed by the urgency of utterance, obsessed by the need to see for themselves, and endowed with the gift to speak for us all.
