    The guru of Sixties radicals, Alinsky urged his followers to be flexible and opportunistic and say anything to get power, which they can then use to radically change existing social and economic institutions. In this insightful new booklet, Horowitz discusses Alinsky’s work in the 60s—and his advice to radicals to seize any weapon to advance their cause. This became the philosophy of Alinskyite organizations such as ACORN and influenced the future President who came up through the Chicago network created by Alinsky’s network. After analyzing Saul Alinsky’s work and pointing out that the godfather of “social organizing” created “ not salvation but chaos,” Horowitz then he asks the crucial question: “And presidential disciples of Alinsky, what will they create?”

    His apothegm "Cogito, ergo sum" marked the birth of the mind-body problem, while his creation of so-called Cartesian coordinates have made our physical and intellectual conquest of physical space possible.But Descartes had a mysterious and mystical side, as well. Almost certainly a member of the occult brotherhood of the Rosicrucians, he kept a secret notebook, now lost, most of which was written in code. After Descartes's death, Gottfried Leibniz, inventor of calculus and one of the greatest mathematicians in history, moved to Paris in search of this notebook--and eventually found it in the possession of Claude Clerselier, a friend of Descartes. Leibniz called on Clerselier and was allowed to copy only a couple of pages--which, though written in code, he amazingly deciphered there on the spot. Leibniz's hastily scribbled notes are all we have today of Descartes's notebook, which has disappeared.Why did Descartes keep a secret notebook, and what were its contents? The answers to these questions lead Amir Aczel and the reader on an exciting, swashbuckling journey, and offer a fascinating look at one of the great figures of Western culture.

    In 1985 Hans von Ohain, the scientist who pioneered Nazi Germany's efforts to build a jet plane, posed the question: 'Would World War II have occured if the Luftwaffe knew it faced operational British jets instead of Spitfires?' He immediately answered, 'I, for one, think not.'Frank Whittle, working-class outsider and self-taught enthusiast, had worked out the blueprint of a completely new type of engine in 1929, only for his ideas to be blocked by bureaucratic opposition until the outbreak of war in 1939. The importance of his work was recognized too late by the government for his revolutionary engine to play a major part in World War II. After the war Whittle's dream of civilian jet-powered aircraft became a reality and Britain enjoyed a golden age of 1950's jet-powered flight.Drawing on Whittle's extensive private papers, Campbell-Smith tells the story of a stoic and overlooked British hero, a tantalizing tale of 'what might have been'.

    This offers the first broad treatment of the city in both its historic and its contemporary aspects.

    do it? How should you flip your mattress to get the maximum wear out of it? How does Google search the Internet? How many people should you date before settling down? Believe it or not, math plays a crucial role in answering all of these questions and more.Math underpins everything in the cosmos, including us, yet too few of us understand this universal language well enough to revel in its wisdom, its beauty — and its joy. This deeply enlightening, vastly entertaining volume translates math in a way that is at once intelligible and thrilling. Each trenchant chapter of The Joy of x offers an “aha!” moment, starting with why numbers are so helpful, and progressing through the wondrous truths implicit in π, the Pythagorean theorem, irrational numbers, fat tails, even the rigors and surprising charms of calculus. Showing why he has won awards as a professor at Cornell and garnered extensive praise for his articles about math for the New York Times, Strogatz presumes of his readers only curiosity and common sense. And he rewards them with clear, ingenious, and often funny explanations of the most vital and exciting principles of his discipline.Whether you aced integral calculus or aren’t sure what an integer is, you’ll find profound wisdom and persistent delight in The Joy of x.

    

    My grandfather, my father, Maria Eugenia, my sister, were all considered mad and I was as well. The reason was that we took a different path to everybody else.'Rafael Bielsa, Marcelo's brother, Foreign Secretary of Argentina, 2003-05. Marcelo Bielsa is one of football's greatest eccentrics and greatest enigmas. He is described by Pep Guardiola as: 'the greatest football manager in the world'. To the Tottenham manager, Mauricio Pochettino, he is 'my footballing father, the reason I became a player, the reason I became a manager.' This will be the first English biography of one of football's most contradictory characters. This is a definitive and comprehensive biography from growing up in Argentina under a military dictatorship to reviving the stricken power of Leeds United.

    The author believes that there are such things as "The Mathematics of Life" and "The Mathematics of Art," and that the two coincide. Using simple mathematical formulas, most as basic as Pythagoras' theorem and requiring only a very limited knowledge of mathematics, Professor Ghyka shows the fascinating relationships between geometry, aesthetics, nature, and the human body.Beginning with ideas from Plato, Pythagoras, Archimedes, Ockham, Kepler, and others, the author explores the outlines of an abstract science of space, which includes a theory of proportions, an examination of "the golden section," a study of regular and semi-regular polyhedral, and the interlinking of these various shapes and forms. He then traces the transmission of this spatial science through the Pythagorean tradition and neo-Pythagorism, Greek, and Gothic canons of proportion, the Kabbala, Masonic traditions and symbols, and modern applications in architecture, painting, and decorative art. When we judge a work of art, according to his formulation, we are making it conform to a pattern whose outline is laid down in simple geometrical figures; and it is the analysis of these figures both in art and nature that forms the core of Professor Ghyka's book. He also shows this geometry at work in living organisms. The ample illustrations and figures give concrete examples of the author's analysis: the Great Pyramid and tomb of Rameses IV, the Parthenon, Renaissance paintings and architecture, the work of Seurat, Le Corbusier, and flowers, shells, marine life, the human face, and much more.For the philosopher, scientist, archaeologist, art historian, biologist, poet, and artist as well as the general reader who wants to understand more about the fascinating properties of numbers and geometry, and their relationship to art and life, this is a thought-provoking book.

    Essentially, you are estimating a probability, but then updating that estimate based on other things that you know. This book is designed to give you an intuitive understanding of how to use Bayes Theorem. It starts with the definition of what Bayes Theorem is, but the focus of the book is on providing examples that you can follow and duplicate. Most of the examples are calculated in Excel, which is useful for updating probability if you have dozens or hundreds of data points to roll in.

    Even as they bring ease to our lives, these programs are stealing something essential from us.Drawing on psychological and neurological studies that underscore how tightly people’s happiness and satisfaction are tied to performing hard work in the real world, Carr reveals something we already suspect: shifting our attention to computer screens can leave us disengaged and discontented.From nineteenth-century textile mills to the cockpits of modern jets, from the frozen hunting grounds of Inuit tribes to the sterile landscapes of GPS maps, The Glass Cage explores the impact of automation from a deeply human perspective, examining the personal as well as the economic consequences of our growing dependence on computers.With a characteristic blend of history and philosophy, poetry and science, Carr takes us on a journey from the work and early theory of Adam Smith and Alfred North Whitehead to the latest research into human attention, memory, and happiness, culminating in a moving meditation on how we can use technology to expand the human experience.

    They will also develop a deeper understanding of the many interconnections that exist among the different areas of psychology. Goodwin's book not only provides accounts of the lives and contributions of psychology's pioneers set into historical context; it also contains original writings by these psychologists, interwoven with informative comments from the author. The text is written in a conversational and engaging style with discrete attention to recent scholarship in the history of psychology, especially that of the past 150 years.

    Budo Secrets contains the essential teachings of budo's greatest masters of Kendo, Karate, Judo, Aikido, and other disciplines. Timely and instructive, these writings are not just for martial artists—they're for anyone who wants to live life more courageously, with a greater sense of personal confidence and self-control, and with a deeper understanding of others. John Stevens has gathered an eclectic and historically rich collection of teachings that include principles and practice guidelines from training manuals and transmission scrolls, excerpts of texts on budo philosophy, and instructional tales gathered from a number of sources. Since many of the martial arts masters were also fine painters and calligraphers and used brush and ink as a teaching medium, Stevens has included their artwork throughout with explanation and commentary.

    But the most significant danger posed by socialism isn’t that its implementation would lead to greater poverty and fewer property rights, it’s that socialism would create numerous moral problems, including the limits it would place on individual liberty and religious freedom. In Socialism Is Evil: The Moral Case Against Marx’s Radical Dream, conservative columnist and think tank research fellow Justin Haskins examines the moral perils of Marx’s socialism and explains why if socialism were to be imposed in its fullest form, it wouldn’t just damage people’s freedoms, it would obliterate them. Haskins argues it would be dangerous to attempt to create Marx’s utopian socialist world, and even more importantly, that such an attempt would be so highly immoral that it could reasonably be called “evil.” In Socialism Is Evil, Haskins makes the moral case against socialism and also describes in detail what socialists believe, the differences between socialism and communism, why Marx’s socialism will never be completely adopted, and why even the more moderate European-style socialism, called “democratic socialism” by some, is highly immoral and anti-American. Many socialists are kind, generous people with good intentions, but sometimes, good intentions can create devastating results. Socialism Is Evil briefly tackles some of the most important moral controversies surrounding Marx’s socialism, providing supporters of individual liberty with the tools they need to stop the rise of socialism in its tracks.
