With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.

    - predicted the reappearance of a lost planet, - discovered basic properties of magnetic forces, - invented a surveying tool used by professionals until the invention of lasers. Based on extensive research of original and secondary sources, this historical narrative will inspire young readers and even curious adults with its touching story of personal achievement.

    or a bit of both.The interests of Athanasius Kircher, the legendary seventeenth-century priest-scientist, knew no bounds. From optics to music to magnetism to medicine, he offered up inventions and theories for everything, and they made him famous across Europe. His celebrated museum in Rome featured magic lanterns, speaking statues, the tail of a mermaid, and a brick from the Tower of Babel. Holy Roman Emperors were his patrons, popes were his friends, and in his spare time he collaborated with the Baroque master Bernini.But Kircher lived during an era of radical transformation, in which the old approach to knowledge - what he called the "art of knowing" - was giving way to the scientific method and modern thought. A Man of Misconceptions traces the rise, success, and eventual fall of this fascinating character as he attempted to come to terms with a changing world.With humor and insight, John Glassie returns Kircher to his rightful place as one of history’s most unforgettable figures.A Scientific American Best Science Book of 2012An Atlantic Wire Best Book of 2012A New York Times Book Review "Editor's Choice”

    In it, we follow them from sixth-century Alexandria to ninth-century Baghdad, from Muslim Cordoba to Catholic Toledo, from Salerno’s medieval medical school to Palermo, capital of Sicily’s vibrant mix of cultures and – finally – to Venice, where that great merchant city’s printing presses would enable Euclid’s geometry, Ptolemy’s system of the stars and Galen’s vast body of writings on medicine to spread even more widely. In tracing these fragile strands of knowledge from century to century, from east to west and north to south, Moller also reveals the web of connections between the Islamic world and Christendom, connections that would both preserve and transform astronomy, mathematics and medicine from the early Middle Ages to the Renaissance. Vividly told and with a dazzling cast of characters, The Map of Knowledge is an evocative, nuanced and vibrant account of our common intellectual heritage.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    Brilliant, driven, but haunted by demons, William Stewart Halsted took surgery from a horrific, dangerous practice to what we now know as a lifesaving art. Halsted was born to wealth and privilege in New York City in the mid-1800s. He attended the finest schools, but he was a mediocre student. His academic interests blossomed at medical school and he quickly became a celebrated surgeon. Experimenting with cocaine as a local anesthetic, he became addicted. He was hospitalized and treated with morphine to control his craving for cocaine. For the remaining 40 years of his life he was addicted to both drugs.Halsted resurrected his career at Johns Hopkins, where he became the first chief of surgery. Among his accomplishments, he introduced the residency training system, the use of sterile gloves, the first successful hernia repair, radical mastectomy, fine silk sutures, and anatomically correct surgical technique. Halsted is without doubt the father of modern surgery, and his eccentric behavior, unusual lifestyle, and counterintuitive productivity in the face of lifelong addiction make his story unusually compelling.Gerald Imber, a renowned surgeon himself, evokes Halsted's extraordinary life and achievements and places them squarely in the historical and social context of the late 19th century. The result is an illuminating biography of a complex and troubled man, whose genius we continue to benefit from today.

    He was a celebrity during the height of America’s Gilded Age. In this book, you will read about his friendship with Mark Twain, his furious competition with his former employer Thomas Edison, his uneasy relationship with billionaire J.P. Morgan, and his rivalry with Albert Einstein. During his lifetime, Tesla revolutionized the field of electrical engineering with his most famous invention: the induction motor. But that wasn’t all he contributed to the world of technology. His coils, turbines, robotic boats, and mysterious “death ray” continue to beguile the imagination and inspire the inventors of the 21st century. But who was Tesla really? This book will take you from his early childhood in Croatia, where he experienced strange optical visions and “luminous phenomenon” that gave him near super-human powers of memory and visualization, to the “War of the Currents”, Thomas Edison’s bizarre campaign to ruin Tesla’s reputation. From trying to fight the Spanish American War with robots, to electrifying the skies of the Colorado desert, and to starting an earthquake in the middle of New York city, learn how Nikola Tesla shaped the world we live in today.

    As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.

    Bell, a leading figure in mathematics in America for half a century. Men of Mathematics accessibly explains the major mathematics, from the geometry of the Greeks through Newton's calculus and on to the laws of probability, symbolic logic, and the fourth dimension. In addition, the book goes beyond pure mathematics to present a series of engrossing biographies of the great mathematicians -- an extraordinary number of whom lived bizarre or unusual lives. Finally, Men of Mathematics is also a history of ideas, tracing the majestic development of mathematical thought from ancient times to the twentieth century. This enduring work's clear, often humorous way of dealing with complex ideas makes it an ideal book for the non-mathematician.

    For centuries following the fall of Rome, western Europe was a benighted backwater, a world of subsistence farming, minimal literacy, and violent conflict. Meanwhile Arab culture was thriving, dazzling those Europeans fortunate enough to catch even a glimpse of the scientific advances coming from Baghdad, Antioch, or the cities of Persia, Central Asia, and Muslim Spain. T here, philosophers, mathematicians, and astronomers were steadily advancing the frontiers of knowledge and revitalizing the works of Plato and Aristotle. I n the royal library of Baghdad, known as the House of Wisdom, an army of scholars worked at the behest of the Abbasid caliphs. At a time when the best book collections in Europe held several dozen volumes, the House of Wisdom boasted as many as four hundred thousand.Even while their countrymen waged bloody Crusades against Muslims, a handful of intrepid Christian scholars, thirsty for knowledge, traveled to Arab lands and returned with priceless jewels of science, medicine, and philosophy that laid the foundation for the Renaissance. I n this brilliant, evocative book, Lyons shows just how much "Western" culture owes to the glories of medieval Arab civilization, and reveals the untold story of how Europe drank from the well of Muslim learning.

    Told here for the first time, the dramatic tale of how the secrets of the brain were discovered in seventeenth-century England unfolds against a turbulent backdrop of civil war, the Great Fire of London, and plague. At the beginning of that chaotic century, no one knew how the brain worked or even what it looked like intact. But by the century's close, even the most common conceptions and dominant philosophies had been completely overturned, supplanted by a radical new vision of man, God, and the universe. Presiding over the rise of this new scientific paradigm was the founder of modern neurology, Thomas Willis, a fascinating, sympathetic, even heroic figure at the center of an extraordinary group of scientists and philosophers known as the Oxford circle. Chronicled here in vivid detail are their groundbreaking revelations and the often gory experiments that first enshrined the brain as the physical seat of intelligence -- and the seat of the human soul. Soul Made Flesh conveys a contagious appreciation for the brain, its structure, and its many marvelous functions, and the implications for human identity, mind, and morality.

    The popular image of the men who made the bomb is of dispassionate intellects who number-crunched their way towards a weapon whose devastating power they could not even imagine. But in his Tony Award-winning play Copenhagen, Michael Frayn shows us that these men were passionate, philosophical, and all too human, even though one of the three historical figures in his drama, Werner Heisenberg, was the head of the Nazis' effort to develop a nuclear weapon. The play's other two characters, the Danish physicist Niels Bohr and his wife, Margrethe, are involved with Heisenberg in an after-death analysis of an actual meeting that has long puzzled historians. In 1941, the German scientist visited Bohr, his old mentor and long-time friend, in Copenhagen. After a brief discussion in the Bohrs' home, the two men went for a short walk. What they discussed on that walk, and its implications for both scientists, have long been a mystery, even though both scientists gave (conflicting) accounts in later years. Frayn's cunning conceit is to use the scientific underpinnings of atomic physics, from Schr?dinger's famous cat to the Heisenberg uncertainty principle, to explore how an individual's point of view renders attempts to discover the ultimate truth of any human interaction fundamentally impossible. To Margrethe, Heisenberg was always an untrustworthy student, eager to steal from her husband's knowledge. To Bohr, Heisenberg was a brilliant if irresponsible foster son, whose lack of moral compass was part of his genius. As for Heisenberg, the man who could have built the bomb but somehow failed to, his dilemma is at the heart of the play's conflict. Frayn's clever dramatic structure, which returns repeatedly to particular scenes from different points of view, allows several possible theories as to what his motives could have been. This isn't the first play to successfully merge the world

    Based on a National Magazine Award-winning article, this masterful biography of Hungarian-born Paul Erdos is both a vivid portrait of an eccentric genius and a layman's guide to some of this century's most startling mathematical discoveries.

    By the middle of the twentieth century, it was killing millions and, as with the Black Death centuries before, physicians stood helpless. Visionaries, though, had begun to make strides earlier. On September 7, 1895, Ludwig Rehn successfully sutured the heart of a living man with a knife wound to the chest for the first time. In 1929, Dr. Werner Forssman inserted a cardiac catheter in his own arm and forced the X-ray technician on duty to take a photo as he successfully threaded it down the vein into his own heart . . . and lived. And on June 6, 1944 D-Day another momentous event occurred far from the Normandy beaches: Dr. Dwight Harken sutured the shrapnel-injured heart of a young soldier and saved his life, and thus the term "cardiac surgeon" was born. In "The Heart Healers," James Forrester, MD, tells the story of these rebels and the risks they took with their own lives and the lives of others to heal the most elemental of human organs: the heart. The result is a compelling chronicle of a disease and its cure, a disease that is still with us, but one that is slowly being worn away by the "Heart Healers."
