Petr Beckmann holds up this mirror, giving the background of the times when pi made progress -- and also when it did not, because science was being stifled by militarism or religious fanaticism.

    Feynman (1918–1988)—physicist, teacher, author, and cultural icon. His autobiographies and biographies have been read and enjoyed by millions of readers around the world, while his wit and eccentricities have made him the subject of TV specials and even a theatrical film. The spectacular reception of the book and audio versions of Feynman’s Six Easy Pieces (published in 1995) resulted in a worldwide clamor for “More Feynman! More Feynman!” The outcome is these six additional lectures, drawn from the celebrated three-volume Lectures on Physics. Though slightly more challenging than the first six, these lectures are more focused, delving into the most revolutionary discovery in twentieth-century physics: Einstein’s Theory of Relativity. No single breakthrough in twentieth-century physics (with the possible exception of quantum mechanics) changed our view of the world more than that of Einstein’s discovery of relativity. The notions that the flow of time is not a constant, that the mass of an object depends on its velocity, and that the speed of light is a constant no matter what the motion of the observer, at first seemed shocking to scientists and laymen alike. But, as Feynman shows so clearly and so entertainingly in the lectures chosen for this volume, these crazy notions are no mere dry principles of physics, but are things of beauty and elegance. No one—not even Einstein himself—explained these difficult, anti-intuitive concepts more clearly, or with more verve and gusto, than Richard Feynman.

    A gripping love declaration to Africa with the troubles of Rhodesia/Zimbabwe as background, the real protagonist of this book is Africa with all her wonders and horrors. "Highly recommended for lovers of the continent, especially those longing for a well-balanced and honest insider’s account of recent African history (B. Pataki 2013) "

    Based on 114 intriguing interviews with nineteen former chief justices of India and more than sixty-six former judges of the Supreme Court of India, Abhinav Chandrachud opens a window to the life and times of the former judges of India's highest court of law and in the process offers a history that largely remained in oblivion for a long time.

    Bill Gates, Bono, and Laura Bush are only a few of the personalities who have lent their names--and opened their pocketbooks--in hopes of curing the disease. Still, in a time when every emergent disease inspires waves of panic, why aren't we doing more to eradicate one of our oldest foes? And how does a parasitic disease that we've known how to prevent for more than a century still infect 500 million people every year, killing nearly 1 million of them? In "The Fever," the journalist Sonia Shah sets out to answer these questions, delivering a timely, inquisitive chronicle of the illness and its influence on human lives. Through the centuries, she finds, we've invested our hopes in a panoply of drugs and technologies, and invariably those hopes have been dashed. From the settling of the New World to the construction of the Panama Canal, through wars and the advances of the Industrial Revolution, Shah tracks malaria's jagged ascent and the tragedies in its wake, revealing a parasite every bit as persistent as the insects that carry it. With distinguished prose and original reporting from Panama, Malawi, Cameroon, India, and elsewhere, "The Fever" captures the curiously fascinating, devastating history of this long-standing thorn in the side of humanity.

    He constructed a fleet of customized unicycles and a flamethrowing trumpet, outfoxed Vegas casinos, and built juggling robots. He also wrote the seminal text of the digital revolution, which has been called “the Magna Carta of the Information Age.” His discoveries would lead contemporaries to compare him to Albert Einstein and Isaac Newton. His work anticipated by decades the world we’d be living in today—and gave mathematicians and engineers the tools to bring that world to pass.In this elegantly written, exhaustively researched biography, Jimmy Soni and Rob Goodman reveal Claude Shannon’s full story for the first time. It’s the story of a small-town Michigan boy whose career stretched from the era of room-sized computers powered by gears and string to the age of Apple. It’s the story of the origins of our digital world in the tunnels of MIT and the “idea factory” of Bell Labs, in the “scientists’ war” with Nazi Germany, and in the work of Shannon’s collaborators and rivals, thinkers like Alan Turing, John von Neumann, Vannevar Bush, and Norbert Wiener.And it’s the story of Shannon’s life as an often reclusive, always playful genius. With access to Shannon’s family and friends, A Mind at Play brings this singular innovator and creative genius to life.

    . . full of intellectual treats and tricks, of whimsy and deep scientific philosophy. It is highbrow entertainment at its best, a teasing challenge to all who aspire to think about the universe." — New York Herald TribuneOne of the world's foremost nuclear physicists (celebrated for his theory of radioactive decay, among other accomplishments), George Gamow possessed the unique ability of making the world of science accessible to the general reader.He brings that ability to bear in this delightful expedition through the problems, pleasures, and puzzles of modern science. Among the topics scrutinized with the author's celebrated good humor and pedagogical prowess are the macrocosm and the microcosm, theory of numbers, relativity of space and time, entropy, genes, atomic structure, nuclear fission, and the origin of the solar system.In the pages of this book readers grapple with such crucial matters as whether it is possible to bend space, why a rocket shrinks, the "end of the world problem," excursions into the fourth dimension, and a host of other tantalizing topics for the scientifically curious. Brimming with amusing anecdotes and provocative problems, One Two Three . . . Infinity also includes over 120 delightful pen-and-ink illustrations by the author, adding another dimension of good-natured charm to these wide-ranging explorations.Whatever your level of scientific expertise, chances are you'll derive a great deal of pleasure, stimulation, and information from this unusual and imaginative book. It belongs in the library of anyone curious about the wonders of the scientific universe. "In One Two Three . . . Infinity, as in his other books, George Gamow succeeds where others fail because of his remarkable ability to combine technical accuracy, choice of material, dignity of expression, and readability." — Saturday Review of Literature

    However, as is perhaps not very politically correct to point out, Islam as a religion calls Muslims to be a part of Ummah, which is to say, that all Muslims belong to the same theological ‘country’ regardless of political borders.That coupled with the intrinsic need of the Left to forever consider the Muslims as the victims, even under imaginary circumstances led to massive riots and violence in India. The perceived wrong here was that CAA left Muslims out, however, the truth was the CAA had nothing to do with Indians at all, let alone Indian Muslims.Another excuse for the rampant violence was that the proposed NRC would snatch away the citizenship of Muslims. That too, was a shameless canard. The NRC, when implemented and drafted, would be aimed to identify and deport Illegal Immigrants, and not Indian Citizens. No country in the world wantonly accepts indiscriminate influx of illegals, but the Left and Islamist nexus burnt the country because that is exactly what it expected of India.While many people wish to look at the Delhi Riots 2020 in isolation, the events that started right from the 1st December 2019 proves otherwise. It proves that the violence was a concerted effort to push Anarchy and Chaos in India. It proves that the Delhi Riots was no anti-Muslim pogrom, it was indeed, a well-oiled plan to tame ‘kafirs’.

    But it is Stella’s voice, the amazing way that she tells her story, that makes this Holocaust story so unique, powerful and endearing. The reader listens to Stella’s stunning simplicity of expression, her use of Polish and Yiddish phrases, her humor, her all-so-frequent grammatical errors – and is charmed.

    B-36 crews trained for the one flight when they would be ordered to drop combat nuclear bombs on the USSR. Flights of fifteen hours over continental United States to grueling thirty-hour nonstop flights overseas were routine, all without the benefit of in-flight refueling—not yet invented. The experiences of this crew, as they flew their assigned missions, are part of the history of our nation’s defense. They were part of our Cold War Shield.

    The chafing restrictions of a typical upbringing in upper-class, small town Alabama simply did not apply to Zelda, who was described as an unusual child and permitted to roam the streets with little supervision. Zelda refused to blossom into a typical 'Southern belle' on anyone's terms but her own and while still in high school enjoyed the status of a local celebrity for her shocking behavior. Everybody in town knew the name Zelda Sayre. Queen of the Montgomery social scene, Zelda had a different beau ready and willing to show her a good time for every day of the week. Before meeting F. Scott Fitzgerald, Zelda's life was a constant pursuit of pleasure. With little thought for the future and no responsibilities to speak of, Zelda committed herself fully to the mantra that accompanied her photo in her high school graduation book: "Why should all life be work, when we all can borrow. Let's think only of today, and not worry about tomorrow." But for now Zelda was still in rehearsal for her real life to begin, a life she was sure would be absolutely extraordinary. Zelda Sayre married F. Scott Fitzgerald on the 3rd of April 1920 and left sleepy Montgomery behind in order to dive headfirst into the shimmering, glamourous life of a New York socialite. With the publication of Scott's first novel, This Side of Paradise, Zelda found herself thrust into the limelight as the very epitome of the Flapper lifestyle. Concerned chiefly with fashion, wild parties and flouting social expectations, Zelda and Scott became icons of the Jazz Age, the personification of beauty and success. What Zelda and Scott shared was a romantic sense of self-importance that assured them that their life of carefree leisure and excess was the only life really worth living. Deeply in love, the Fitzgeralds were like to sides of the same coin, each reflecting the very best and worst of each other. While the world fell in love with the image of the Fitzgeralds they saw on the cover of magazines, behind the scenes the Fitzgerald's marriage could not withstand the tension of their creative arrangement. Zelda was Scott's muse and he mercilessly mined the events of their life for material for his books. Scott claimed Zelda's memories, things she said, experiences she had and even passages from her diary as his possessions and used them to form the basis of his fictional works. Zelda had a child but the domestic sphere offered no comfort or purpose for her. The Flapper lifestyle was not simply a phase she lived through, it formed the very basis of her character and once the parties grew dull, the Fitzgeralds' drinking became destructive and Zelda's beauty began to fade, the world held little allure for her. Zelda sought reprieve in work and tried to build a career as a ballet dancer. When that didn't work out she turned to writing but was forbidden by Scott from using her own life as material. Convinced that she would never leave her mark on the world as deeply or expressively as Scott had, Zelda retreated into herself and withdrew from the people she knew in happier times. The later years of Zelda's life were marred by her detachment from reality as, diagnosed with schizophrenia, Zelda spent the last eighteen years of her life living in and out of psychiatric hospitals. As Scott's life unraveled due to alcohol abuse, Zelda looked back on the years they had spent together, young and wild and beautiful, as the best of her life. She may have been right but she was wrong about one thing, Zelda did leave her mark on the world and it was a deep and expressive mark that no one could have left but her. Zelda Fitzgerald: The Biography

    After several failed attempts he got out over the wire and journeyed for weeks as a fugitive from northern France to Marseilles, then across the Pyrenees to Spain and Gibraltar and freedom. He was guided along the way by French civilians, resistance fighters and the organizers of the famous Pat escape line. His straightforward, honest and vivid memoir of his work as a surgeon at Dunkirk, life in the prison camps and his escape attempts gives a fascinating insight into his wartime experience. It records the ingenuity and courage of the individuals, the ordinary men and women, who risked their lives to help him on his way. It is also one of the best accounts we have of what it was like to be on the run in occupied Europe.

    As we enter the year 2000, zero is once again making its presence felt. Nothing itself, it makes possible a myriad of calculations. Indeed, without zero mathematicsas we know it would not exist. And without mathematics our understanding of the universe would be vastly impoverished. But where did this nothing, this hollow circle, come from? Who created it? And what, exactly, does it mean? Robert Kaplan's The Nothing That Is: A Natural History of Zero begins as a mystery story, taking us back to Sumerian times, and then to Greece and India, piecing together the way the idea of a symbol for nothing evolved. Kaplan shows us just how handicapped our ancestors were in trying to figurelarge sums without the aid of the zero. (Try multiplying CLXIV by XXIV). Remarkably, even the Greeks, mathematically brilliant as they were, didn't have a zero--or did they? We follow the trail to the East where, a millennium or two ago, Indian mathematicians took another crucial step. By treatingzero for the first time like any other number, instead of a unique symbol, they allowed huge new leaps forward in computation, and also in our understanding of how mathematics itself works. In the Middle Ages, this mathematical knowledge swept across western Europe via Arab traders. At first it was called dangerous Saracen magic and considered the Devil's work, but it wasn't long before merchants and bankers saw how handy this magic was, and used it to develop tools likedouble-entry bookkeeping. Zero quickly became an essential part of increasingly sophisticated equations, and with the invention of calculus, one could say it was a linchpin of the scientific revolution. And now even deeper layers of this thing that is nothing are coming to light: our computers speakonly in zeros and ones, and modern mathematics shows that zero alone can be made to generate everything.Robert Kaplan serves up all this history with immense zest and humor; his writing is full of anecdotes and asides, and quotations from Shakespeare to Wallace Stevens extend the book's context far beyond the scope of scientific specialists. For Kaplan, the history of zero is a lens for looking notonly into the evolution of mathematics but into very nature of human thought. He points out how the history of mathematics is a process of recursive abstraction: how once a symbol is created to represent an idea, that symbol itself gives rise to new operations that in turn lead to new ideas. Thebeauty of mathematics is that even though we invent it, we seem to be discovering something that already exists.The joy of that discovery shines from Kaplan's pages, as he ranges from Archimedes to Einstein, making fascinating connections between mathematical insights from every age and culture. A tour de force of science history, The Nothing That Is takes us through the hollow circle that leads to infinity.

    Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of quantum mechanics. There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible to readers with scientific backgrounds, as well as students and researchers working in physics, computer science, mathematics and philosophy.

    Egypt’s 2011 revolt was no exception. The military’s abandonment of Mubarak—a turning point for the revolt—confounded many observers, who assumed that the leader and the generals stood or fell together. The officers, it was thought, ruled from behind the scenes and simply swapped the figures in the spotlight to preserve the status quo.In a challenge to this conventional view, Hazem Kandil presents the revolution as the latest episode in an ongoing power struggle between the three components of Egypt’s authoritarian regime: the military, the security services, and the political apparatus. A detailed study of the interactions within this invidious triangle over six decades of war, conspiracy, and sociopolitical transformation, Soldiers, Spies, and Statesmen is the first systematic analysis of how Egypt metamorphosed from a military into a police state—and what that means for the future of its revolution.
