And proves once and for all that maths isn't just for old men with white hair and beards who associate with elves.Maths has never been merrier.

    He was such a daydreamer that people called him a blockhead.When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. The boy who was once teased for being a blockhead had discovered what came to be known as the Fibonacci Sequence!

    Is God a Mathematician? investigates why mathematics is as powerful as it is. From ancient times to the present, scientists and philosophers have marveled at how such a seemingly abstract discipline could so perfectly explain the natural world. More than that—mathematics has often made predictions, for example, about subatomic particles or cosmic phenomena that were unknown at the time, but later were proven to be true. Is mathematics ultimately invented or discovered? If, as Einstein insisted, mathematics is “a product of human thought that is independent of experience,” how can it so accurately describe and even predict the world around us? Physicist and author Mario Livio brilliantly explores mathematical ideas from Pythagoras to the present day as he shows us how intriguing questions and ingenious answers have led to ever deeper insights into our world. This fascinating book will interest anyone curious about the human mind, the scientific world, and the relationship between them.

    Now they are alone. With the war raging around them, food and shelter are hard to come by. They live in constant fear.Finally, they get word that their father is alive. He has made it to Switzerland. Edek and Ruth are determined to find him, though they know how dangerous the long trip from Warsaw will be. But they also know that if they don't make it, they may never see their parents again.Their gripping story is taken from actual accounts.

    Abbott published a brilliant novel about mathematics and philosophy that charmed and fascinated all of England. As both a witty satire of Victorian society and a means by which to explore the fourth dimension, Flatland remains a tour de force. Now, British mathematician and accomplished science writer Ian Stewart has written a fascinating, modern sequel to Abbott's book. Through larger-than-life characters and an inspired story line, Flatterland explores our present understanding of the shape and origins of the universe, the nature of space, time, and matter, as well as modern geometries and their applications. The journey begins when our heroine, Victoria Line, comes upon her great-great-grandfather A. Square's diary, hidden in the attic. The writings help her to contact the Space Hopper, who becomes her guide and mentor through eleven dimensions. Along the way, we meet Schröger's Cat, The Charming Construction Entity, The Mandelblot (who lives in Fractalia), and Moobius the one-sided cow. In the tradition of Alice in Wonder-land and The Phantom Toll Booth, this magnificent investigation into the nature of reality is destined to become a modern classic.

    But sometimes the solutions are not as interesting as the beautiful symmetric patterns that lead to them. Written in a friendly style for a general audience, Fearless Symmetry is the first popular math book to discuss these elegant and mysterious patterns and the ingenious techniques mathematicians use to uncover them.Hidden symmetries were first discovered nearly two hundred years ago by French mathematician �variste Galois. They have been used extensively in the oldest and largest branch of mathematics--number theory--for such diverse applications as acoustics, radar, and codes and ciphers. They have also been employed in the study of Fibonacci numbers and to attack well-known problems such as Fermat's Last Theorem, Pythagorean Triples, and the ever-elusive Riemann Hypothesis. Mathematicians are still devising techniques for teasing out these mysterious patterns, and their uses are limited only by the imagination.The first popular book to address representation theory and reciprocity laws, Fearless Symmetry focuses on how mathematicians solve equations and prove theorems. It discusses rules of math and why they are just as important as those in any games one might play. The book starts with basic properties of integers and permutations and reaches current research in number theory. Along the way, it takes delightful historical and philosophical digressions. Required reading for all math buffs, the book will appeal to anyone curious about popular mathematics and its myriad contributions to everyday life.

    This country house was home to Britain's most brilliant mathematical brains, like Alan Turing, and the scene of immense advances in technology—indeed, the birth of modern computing. The military codes deciphered there were instrumental in turning both the Battle of the Atlantic and the war in North Africa. But, though plenty has been written about the scientists and the codebreaking, fictional and non-fiction—from Robert Harris and Ian McEwan to Andrew Hodges' biography of Turing—what of the thousands of men and women who lived and worked there during the war? The first history for the general reader of life at Bletchley Park, this is also an amazing compendium of memories from people now in their eighties of skating on the frozen lake in the grounds (a depressed Angus Wilson, the novelist, once threw himself in), of a youthful Roy Jenkins—useless at codebreaking, of the high jinks at nearby accommodation hostels, and of the implacable secrecy that meant girlfriend and boyfriend working in adjacent huts knew nothing about each other's work.

    Ballroom dancing, flying fighter planes, detonating bombs, skinning and eating snakes in times of dire need, and everything else in between—there’s nothing our officers can’t do!Read twenty-one nail-biting stories of daring. Hear from some amazing men and women about what the forces have taught them—and decide if the olivegreen uniform is what you want to wear too.

    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    The poet J. Patrick Lewishas reimagined classic poems—such as Edgar Allan Poe’s “The Raven” and LangstonHughes’s “April Rain Song”—and added a dash of math. Between the silly parodiesand the wonderfully wacky art, kids will have so much fun figuring out the puzzles,they won’t guess they’re learning! Answers appear unobtrusively on each page, andengaging information about the original poets is included. Math games and concepts,poetry and poet biographies—it’s all so cleverly put together. This funny book is atreat for fans of words and numbers alike.

    Why does elf + elf = fool? How many meals will Miss Mush, the lunch teacher, have to cook for the food to taste as bad as it smells?

    At the peak of U.S. involvement in the war, nearly one in five American soldiers was foreign-born. Many of these immigrant soldiers - most of whom had been drafted - knew little of America outside of tight-knit ghettos and backbreaking labor. Yet World War I would change the lives and ultimately reshape the nation itself. Italians, Jews, Poles, Norwegians, Sovaks, Russians, and Irishmen entered te army as aliens and returned as Americans, often as heroes.In The Long Way Home, award-winning writer David Laskin traces the lives of a dozen men, eleven of whom left their childhood homes in Europe, journeyed through Ellis Island, and started over in a strange land. After detailing the daily realities of immigrant life in the factories, farms, mines, and cities of a rapidly growing nation, Laskin tells the heartbreaking stories of how these men - both conscripts and volunteers - joined the army, were swept into the ordeal of boot camp, and endured the month of hell that ended the war at Argonne, where they truly became Americans. Those who survived were profoundly altered - and their experiences would shape the lives of their families as well.Epic, inspiring, and masterfully written, The Long Way Home is the unforgettable true story of the Great War, the world it remade, and the men who fought for a country not of their birth, but which held the hope and opportunity of a better way of life.
