Beginning millions of years ago with ancient “ant odometers” and moving through time to our modern-day quest for new dimensions, it covers 250 milestones in mathematical history. Among the numerous delights readers will learn about as they dip into this inviting anthology: cicada-generated prime numbers, magic squares from centuries ago, the discovery of pi and calculus, and the butterfly effect. Each topic gets a lavishly illustrated spread with stunning color art, along with formulas and concepts, fascinating facts about scientists’ lives, and real-world applications of the theorems.

    Rejecting the view that anyone has a natural right to wield authority over others, Rousseau argues instead for a pact, or ‘social contract’, that should exist between all the citizens of a state and that should be the source of sovereign power. From this fundamental premise, he goes on to consider issues of liberty and law, freedom and justice, arriving at a view of society that has seemed to some a blueprint for totalitarianism, to others a declaration of democratic principles.

    But his penetrating work of political philosophy - now fully revised and with a new introduction for this edition - opened up questions about the nature of statecraft and society that influenced governments across the world.

    In telling the story of one master’s training and evolution in the Himalayas and his subsequent mission to his countrymen, the author enlightens you on the essence of India’s culture, philosophy and religion. His story will surely educate you, inspire you, and broaden your horizons of the meaning of life.The Swami spent five years in the Himalayas under the tutelage of two incredible Masters of live, as different as day and night. Although both were scholars of the scriptures, their manifestation was unique. One was an incredible streak of light and energy who traveled India teaching, then created a huge ashram center to serve all of humanity. The other was a quiet contemplative recluse who sang inspirational songs and taught only a few students.Swami Chinmayananda appeared on the scene at an appropriate time in Indian history. The British had just left the country with no one trained to take the helm of State. The British had taken all the top government positions. In addition, they had curtailed any industrial development; the Empire was about having consumers for British products. The Indians had lost their moorings: economically, spiritually and personally. To these countrymen, beaten down by 150 years of British rule, repression and slavery, the Swami gave a message of hope. He worked relentlessly for about 40 years to bring about a spiritual revival in India and abroad. His unique style and logical approach was appreciated by everyone from college students to bankers to priests—both Hindu and Christian.By teaching directly the wisdom of their ancient scriptures, he gave the listeners confidence and inspiration to move forward in business and in creating charitable endeavors for the uplifting of the downtrodden of the country. Through 200 centers in India, his devotees have built and operate schools, hospitals and clinics, nursing homes, retirement homes and training centers for nurses and teachers, as well as spiritual training centers.This story of the legacy of one of the most influential persons in the modern history of Hinduism is sure to surprise you, amaze you—and inspire you.

     Now Roy Sorensen offers the first narrative history of paradoxes, a fascinating and eye-opening account that extends from the ancient Greeks, through the Middle Ages, the Enlightenment, and into the twentieth century. When Augustine asked what God was doing before He made the world, he wastold: Preparing hell for people who ask questions like that. A Brief History of the Paradox takes a close look at questions like that and the philosophers who have asked them, beginning with the folk riddles that inspired Anaximander to erect the first metaphysical system and ending with suchthinkers as Lewis Carroll, Ludwig Wittgenstein, and W.V. Quine. Organized chronologically, the book is divided into twenty-four chapters, each of which pairs a philosopher with a major paradox, allowing for extended consideration and putting a human face on the strategies that have been taken towardthese puzzles. Readers get to follow the minds of Zeno, Socrates, Aquinas, Ockham, Pascal, Kant, Hegel, and many other major philosophers deep inside the tangles of paradox, looking for, and sometimes finding, a way out. Filled with illuminating anecdotes and vividly written, A Brief History of the Paradox will appeal to anyone who finds trying to answer unanswerable questions a paradoxically pleasant endeavor.

    Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    This Penguin Classics edition of The Complete Essays is translated from the French and edited with an introduction and notes by M.A. Screech.In 1572 Montaigne retired to his estates in order to devote himself to leisure, reading and reflection. There he wrote his constantly expanding 'assays', inspired by the ideas he found in books contained in his library and from his own experience. He discusses subjects as diverse as war-horses and cannibals, poetry and politics, sex and religion, love and friendship, ecstasy and experience. But, above all, Montaigne studied himself as a way of drawing out his own inner nature and that of men and women in general. The Essays are among the most idiosyncratic and personal works in all literature and provide an engaging insight into a wise Renaissance mind, continuing to give pleasure and enlightenment to modern readers.With its extensive introduction and notes, M.A. Screech's edition of Montaigne is widely regarded as the most distinguished of recent times.Michel de Montaigne (1533-1586) studied law and spent a number of years working as a counsellor before devoting his life to reading, writing and reflection.If you enjoyed The Complete Essays, you might like Francois Rabelais's Gargantua and Pantagruel, also available in Penguin Classics.'Screech's fine version ... must surely serve as the definitive English Montaigne'A.C.

    But, Alex Bellos says, "math can be inspiring and brilliantly creative. Mathematical thought is one of the great achievements of the human race, and arguably the foundation of all human progress. The world of mathematics is a remarkable place."Bellos has traveled all around the globe and has plunged into history to uncover fascinating stories of mathematical achievement, from the breakthroughs of Euclid, the greatest mathematician of all time, to the creations of the Zen master of origami, one of the hottest areas of mathematical work today. Taking us into the wilds of the Amazon, he tells the story of a tribe there who can count only to five and reports on the latest findings about the math instinct--including the revelation that ants can actually count how many steps they've taken. Journeying to the Bay of Bengal, he interviews a Hindu sage about the brilliant mathematical insights of the Buddha, while in Japan he visits the godfather of Sudoku and introduces the brainteasing delights of mathematical games.Exploring the mysteries of randomness, he explains why it is impossible for our iPods to truly randomly select songs. In probing the many intrigues of that most beloved of numbers, pi, he visits with two brothers so obsessed with the elusive number that they built a supercomputer in their Manhattan apartment to study it. Throughout, the journey is enhanced with a wealth of intriguing illustrations, such as of the clever puzzles known as tangrams and the crochet creation of an American math professor who suddenly realized one day that she could knit a representation of higher dimensional space that no one had been able to visualize. Whether writing about how algebra solved Swedish traffic problems, visiting the Mental Calculation World Cup to disclose the secrets of lightning calculation, or exploring the links between pineapples and beautiful teeth, Bellos is a wonderfully engaging guide who never fails to delight even as he edifies. "Here's Looking at Euclid "is a rare gem that brings the beauty of math to life.

    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.

    A world that is glamorous and alluring can blind its participants to certain truths. This euphoric illusion which is full of money, women, and power, can also be deceiving. You start to believe that the fame will last forever. That the people around you are really your friends, and that the scandalous woman at your side really loves you for the person that you are. Stardom can become dangerous for the naïve souls who rise to success without armor. Tangie, who has mastered The Art Of Deceit slithers her way into the heart of many and into the wallets of even more, her latest victim being Hip Hop’s newest sensation Tay’von-Too Fine- Miller. Tay’von is told by his record label that he needs a better looking woman on his arm because the public will deem his plus size girlfriend unbefitting for a rising star. So he pulls Tangie into his world hoping to use her for her looks, only to get rid of her when he is done. But he has highly underestimated her. Her charm is hypnotic, that of a snake charmer, and as strong as the magic from a voodoo priest. Once she has cast her spell, she is sure to bring any man or woman down to their knees. She rules with a blackened heart and shows no mercy to people like Shamika, the spiteful girlfriend of equally talented but not as successful rapper Black Dialect. Tangie will stop at nothing to secure her lifestyle, even if that means shaking hands with a record label owner who Tay’von has proclaimed a sworn enemy. Carmello wants Tay’von to sign to his record label, and Tangie wants revenge. Together they hatch a plan that will give them both what they want. What will happen when Tay’von, his bodyguard, the sexy R&B tour mate Amira, and Carmello all fall under Tangie’s spell? Death, Debauchery, and Deceit, now if only everything would go as planned.

    A collection of free excerpts from Sister Souljah’s books.

    It's a Tuesday.Bradley Michaels is just another man ending just another workday at just another job. He can list the usual complaints, can point his finger at the usual causes, and he can go about his routine as if one day is absolutely no different from the next. Until God himself just shows up uninvited and shakes up Bradley's entire existence by flaunting his own. It's not fair, but Bradley never claimed life is. And he tries to handle the new, omniscient presence in his head with calm attention and cool collectedness. But God happens to be a bit of a kid. He likes to joke, to prod, to stir things up. And what God sets his mind to, God succeeds at. Just as Bradley believes he's got life all figured out, God has to throw a wrench into it. But not at all in the way that Bradley—or you—can expect. Just when you think life is going according to plan, you find out your plan sucks. And it's time for a new one.

    This work is the result of those requests. It is full of controversial claims, so be warned. I truly believe that if people follow the handful of principles in this short read, they will improve their health and change their lives.

    This book hopes to change that. While hospices care for persons in their final days, hospice is not about death. It’s all about LIFE—real, nitty-gritty, poignant, funny, challenging, and bittersweet life in all its beauty and imperfection. Those who have experienced hospice usually speak in reverential tones of this service and find themselves fearing death less because they have seen all the incredible life that happens until the final moment. But those unfamiliar with hospice often misunderstand and fear it, and the end of life. Through first-hand accounts that range from humorous to heart-wrenchingly honest, Carla shares the stories that continue to teach her the lessons of what it means to be truly present with ourselves and each other in this perfectly imperfect experience called life.
