The invention of numerals is perhaps the greatest abstraction the human mind has ever created. Virtually everything in our lives is digital, numerical, or quantified. The story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is an adventure filled saga of Amir Aczel's lifelong obsession: to find the original sources of our numerals. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride. The history begins with the early Babylonian cuneiform numbers, followed by the later Greek and Roman letter numerals. Then Aczel asks the key question: where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory, to go on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero—the keystone of our entire system of numbers—on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves—who finally reveal where our numbers come from.

A mistake. A drastic fix. And the person most hurt by Jack’s choice turns out to be… Jack. Five years after joining the army, Jack is back on civvy street and struggling to find his feet. He knows he’s made the wrong choice. He knows he needs to move on. But how can he choose a new direction when he feels so lost? Jack asks advice from friends and strangers, but to find his lifeline he must remember who he is, what he stands for, and what first Rio and then Gareth have taught him. Can Jack find his way again? Buy Two Divided by Zero and find out! This is the second book of the Zero Rising series, which is the prequel to the Power of Zero series.

* This book deals with the fundamentals of genetic algorithms and their applications in a variety of different areas of engineering and science * Most significant update to the second edition is the MATLAB codes that accompany the text * Provides a thorough discussion of hybrid genetic algorithms * Features more examples than first edition

The origin story to Jackie Keswick's popular Power of Zero series. Enjoy this poignant coming of age story of courage and hope with a touch of revenge. Who says underdogs don't bite? Twelve-year-old Jack Horwood has run from the pimp his mother sold him to, preferring to take his chances on the streets. A house with a cheerful red door – and a classic convertible out front – prompts him into a spot of breaking and entering, and soon he has a warm, dry basement to squat in. Until the owner of the house, Jamaican hacker Rio Palmer, discovers his hideout. Rio offers him a safe place to stay, but Jack doesn’t believe a word the man says and runs. Rio can’t forget the youngster who is scared and vulnerable, and stronger than many men Rio has met. Finding Jack is a tiny challenge. Teaching him to trust is like climbing a mountain. But when faced with a true zero and its power, Rio can do nothing else. The Power of Zero is the first book in the Zero Rising series, which tells Jack's origin story.

Zero has been axial in human development, but the origin and discovery of zero has never been satisfactorily addressed by a comprehensive, systematic and above all interdisciplinary research program. In this volume, over 40 international scholars explore zero under four broad themes: history; religion, philosophy & linguistics; arts; and mathematics & the sciences. Some propose that the invention/discovery of zero may have been facilitated by the prior evolution of a sophisticated concept of Nothingness or Emptiness (as it is understood in non-European traditions); and conversely, inhibited by the absence of, or aversion to, such a concept of Nothingness in the West. But not all scholars agree. Join the debate.

Elsberg is nothing if not prescient; this is all pre-Cambridge Analytica.' Barry Forshaw, Guardian ************************ The gripping bestselling global thriller for fans of Dave Eggers' THE CIRCLE and Channel Four's BLACK MIRROR. ************************ Welcome to the Freemee lifestyle app: They can give you confidence, power, fame and all the friends in the world. But what will they take in return? When a teenager is shot dead after chasing a criminal in the street, investigating journalist Cynthia Bonsant is led to the popular social media platform Freemee, a competitor to Facebook whose lifestyle app claims to give you everything you need to succeed in life. But there is someone who warns against its evils: Zero, the world’s most-wanted activist, known for exposing the toxic truths behind social media giants and their pursuit of total control. As Cynthia gets closer to unravelling the evil mastermind behind the Freemee site, she herself becomes a target. But in this world of hidden cameras, data glasses and hyper-smart phones there is nowhere to hide . . .

The Grumman F4F Wildcat and the Mitsubishi A6M Zero-sen were contemporaries, although designed to very different requirements. The Wildcat, ruggedly built to survive the rigors of carrier operations, was the best carrier fighter the US Navy had available when the USA entered World War II, and it remained the principal fighter for the US Navy and the US Marine Corps until 1942–43. With a speed greater than 300mph, exceptional manoeuvrability, long range, and an impressive armament the slick Zero-sen could out-perform any Allied fighter in 1941–42. The battles between the Wildcat and the Zero-sen during 1942 represent a classic duel in which pilots flying a nominally inferior fighter successfully developed air-combat tactics that negated the strengths of their opponent.

This book provides an overview of the current state of research on development and application of methods, algorithms, tools and systems associated with the studies on man-machine interaction. Modern machines and computer systems are designed not only to process information, but also to work in dynamic environment, supporting or even replacing human activities in areas such as business, industry, medicine or military. The interdisciplinary field of research on man-machine interactions focuses on broad range of aspects related to the ways in which human make or use computational artifacts, systems and infrastructure. This monograph is the fourth edition in the series and presents new concepts concerning analysis, design and evaluation of man-machine systems. The selection of high-quality, original papers covers a wide scope of research topics focused on the main problems and challenges encountered within rapidly evolving new forms of human-machine relationships. The presented material is structured into following sections: human-computer interfaces, robot, control, embedded and navigation systems, bio-data analysis and mining, biomedical signal processing, image and motion data processing, decision support and expert systems, pattern recognition, fuzzy systems, algorithms and optimisation, computer networks and mobile technologies, and data management systems.

This book presents the basic concepts and algorithms of computer algebra using practical examples that illustrate their actual use in symbolic computation. A wide range of topics are presented, including: Groebner bases, real algebraic geometry, lie algebras, factorization of polynomials, integer programming, permutation groups, differential equations, coding theory, automatic theorem proving, and polyhedral geometry. This book is a must read for anyone working in the area of computer algebra, symbolic computation, and computer science.
