As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from this plus this equals this to this plus what equals this? gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

    The Vinyl Dialogues offers the stories behind 31 of the top albums of the 70s, including backstories behind the albums, the songs, and the artists. It was the 1970s: Big hair, bell-bottomed pants, Elvis sideburns and puka shell necklaces. The drugs, the freedom, the Me Generation, the lime green leisure suits. And then there was the music and how it defined a generation. The birth of Philly soul, the Jersey Shore Sound and disco. It's all there in "The Vinyl Dialogues," as told by the artists who lived and made Rock and Roll history throughout the decade.Throw in a little political intrigue - The Guess Who being asked not to play its biggest hit, "American Woman," at a White House appearance and Brewer and Shipley being called political subversives and making President Nixon's infamous "enemies list" - and "The Vinyl Dialogues offers a first-hand snapshot of a country in transition, hung over from the massive cultural changes of the 1960s and ready to dress outrageously and to shake its collective booty. All seen through the eyes, recollections and perspectives of the artists who lived it and made all that great music on all those great albums.

    In this collection of landmark mathematical works, editor Stephen Hawking has assembled the greatest feats humans have ever accomplished using just numbers and their brains.

    In the centennial season of college football, both teams were undefeated; both featured devastating and innovative offenses; both boasted cerebral, stingy defenses; and both were coached by superior tacticians and stirring motivators, Texas's Darrell Royal and Arkansas's Frank Broyles. On that day in Fayetteville, the poll-leading Horns and second-ranked Hogs battled for the Southwest Conference title -- and President Nixon was coming to present his own national championship plaque to the winners. Even if it had been just a game, it would still have been memorable today. The bitter rivals played a game for the ages before a frenzied, hog-callin' crowd that included not only an enthralled President Nixon -- a noted football fan -- but also Texas congressman George Bush. And the game turned, improbably, on an outrageously daring fourth-down pass.But it "wasn't" just a game, because nothing was so simple in December 1969. In "Horns, Hogs, & Nixon Coming," Terry Frei deftly weaves the social, political, and athletic trends together for an unforgettable look at one of the landmark college sporting events of all time.The week leading up to the showdown saw black student groups at Arkansas, still marginalized and targets of virulent abuse, protesting and seeking to end the use of the song "Dixie" to celebrate Razorback touchdowns; students were determined to rush the field during the game if the band struck up the tune. As the United States remained mired in the Vietnam War, sign-wielding demonstrators (including war veterans) took up their positions outsidethe stadium -- in full view of the president. That same week, Rhodes Scholar Bill Clinton penned a letter to the head of the ROTC program at the University of Arkansas, thanking the colonel for shielding him from induction into the military earlier in the year.Finally, this game was the last major sporting event that featured two exclusively white teams. Slowly, inevitably, integration would come to the end zones and hash marks of the South, and though no one knew it at the time, the Texas vs. Arkansas clash truly was Dixie's Last Stand.Drawing from comprehensive research and interviews with coaches, players, protesters, professors, and politicians, Frei stitches together an intimate, electric narrative about two great teams -- including one player who, it would become clear only later, was displaying monumental courage just to make it onto the field -- facing off in the waning days of the era they defined. Gripping, nimble, and clear-eyed, "Horns, Hogs, & Nixon Coming" is the final word on the last of how it was.

    His voluminous notebooks, the great storehouse of his theories and discoveries, are presented here in 1566 extracts that reveal the full range of Leonardo's versatile interest: all the important writings on painting, sculpture, architecture, anatomy, astronomy, geography, topography, and other fields are included, in both Italian and English, with 186 plates of manuscript pages and many other drawings reproduced in facsimile size.The first volume, which contains all of Leonardo's writings on aspects of painting, includes discussions of such basic scientific areas as the structure of the eye and vision, perspective, the science of light and shade, the perspective of disappearance, theory of color, perspective of color, proportions and movements of the human figure, botany for painters, and the elements of landscape painting. A section on the practice of painting includes moral precepts for painters and writings on composition, materials, and the philosophy of art. The second volume contains writings on sculpture, architecture (plans for towns, streets, and canals, churches, palaces, castles, and villas, theoretical writings on arches, domes, fissures, etc.), zoology, physiology (including his amazingly accurate theories of blood circulation), medicine, astronomy, geography (including has famous writings and drawings on the movement of water), topography (observations in Italy, France, and other areas), naval warfare, swimming, theory of flying machines, mining, music, and other topics.A selection of philosophical maxims, morals, polemics, fables, jests, studies in the lives and habits of animals, tales, and prophecies display Leonardo's abilities as a writer and scholar. The second volume also contains some letters, personal records, inventories, and accounts, and concludes with Leonardo's will. The drawings include sketches and studies for some of Leonardo's greatest works of art — The Last Supper, the lost Battle of Anghiari, The Virgin of the Rocks, and the destroyed Sforza monument.

    Wilczek’s groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring.Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all things are number,” to Galileo, Newton, Maxwell, Einstein, and into the deep waters of twentiethcentury physics. Though the ancients weren’t right about everything, their ardent belief in the music of the spheres has proved true down to the quantum level. Indeed, Wilczek explores just how intertwined our ideas about beauty and art are with our scientific understanding of the cosmos.Wilczek brings us right to the edge of knowledge today, where the core insights of even the craziest quantum ideas apply principles we all understand. The equations for atoms and light are almost literally the same equations that govern musical instruments and sound; the subatomic particles that are responsible for most of our mass are determined by simple geometric symmetries. The universe itself, suggests Wilczek, seems to want to embody beautiful and elegant forms. Perhaps this force is the pure elegance of numbers, perhaps the work of a higher being, or somewhere between. Either way, we don’t depart from the infinite and infinitesimal after all; we’re profoundly connected to them, and we connect them. When we find that our sense of beauty is realized in the physical world, we are discovering something about the world, but also something about ourselves.Gorgeously illustrated, A Beautiful Question is a mind-shifting book that braids the age-old quest for beauty and the age-old quest for truth into a thrilling synthesis. It is a dazzling and important work from one of our best thinkers, whose humor and infectious sense of wonder animate every page. Yes: The world is a work of art, and its deepest truths are ones we already feel, as if they were somehow written in our souls.

    He constructs the story like a detective novel, putting pieces of clues together to form the whole puzzle and he makes an incredibly exciting job of it. He writes for the lay reader but he is far from condescening. His language is a joy to read. I agree with BlairBurton that the book is wildly entertaining but I resented his reference to the author as 'the premier theorist of crackpot science.' Velikovsy's 'crackpot' theories are yet to be disproved and his predictions have the uncanny habit of being proved right so that the world of the scientific community is as shaky as the description of the earth in "Worlds In Collision!" Readers will find great rewards in reading all of his works and judging for themselves. While "Oedipus and Akhnaton" is the least 'scientific' of his works it is no less fascinating and eminently readable.

    Since its creation, the Cube has become many things to many people: one of the bestselling children’s toys of all time, a symbol of intellectual prowess, a frustrating puzzle with 43.2 quintillion possible permutations, and now a worldwide sporting phenomenon that is introducing the classic brainteaser to a new generation. In Cracking the Cube, Ian Scheffler reveals that cubing isn’t just fun and games. Along with participating in speedcubing competitions—from the World Championship to local tournaments—and interviewing key figures from the Cube’s history, he journeys to Budapest to seek a meeting with the legendary and notoriously reclusive Rubik, who is still tinkering away with puzzles in his seventies. Getting sucked into the competitive circuit himself, Scheffler becomes engrossed in solving Rubik’s Cube in under twenty seconds, the quasi-mystical barrier known as “sub-20,” which is to cubing what four minutes is to the mile: the difference between the best and everyone else. For Scheffler, the road to sub-20 is not just about memorizing algorithms or even solving the Rubik’s Cube. As he learns from the many gurus who cross his path, from pint-sized kids to engineering professors, it’s about learning to solve yourself.

    Hardy, in the years before World War I. Through their eyes the reader is taken on a journey through numbers theory. Ramanujan would regularly telescope 12 steps of logic into two - the effect is said to be like Dr Watson in the train of some argument by Sherlock Holmes. The language of symbols and infinitely large (and small) regions of mathematics should be rendered with clarity for the general reader.

    November 2015 is the 100th anniversary of Einstein’s discovery of the General Theory of Relativity.Levenson, head of MIT’s Science Writing Program, tells the captivating, unusual, and nearly-forgotten backstory behind Einstein’s invention of the Theory of Relativity, which completely changed the course of science forever. For over 50 years before Einstein developed his theory, the world’s top astronomers spent countless hours and energy searching for a planet, which came to be named Vulcan, that had to exist, it was thought, given Isaac Newton’s theories of gravity. Indeed, in the two centuries since Newton’s death, his theory had essentially become accepted as fact. It took Einstein’s genius to realize the mystery of the missing planet wasn’t a problem of measurements or math but of Newton’s theory of gravity itself. Einstein’s Theory of Relativity proved that Vulcan did not and could not exist, and that the decades-long search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Thomas Levenson tells this unique story, one of the strangest episodes in the history of science, with elegant simplicity, fast-paced drama, and lively characters sure to capture the attention of a wide group of readers.
