Brains, Machines, and Mathematics | Michael A. Arbib usato Scienze Matematica e Ingegneria

This is a book whose time has come-again. The first edition (published by McGraw-Hill in 1964) was written in 1962, and it celebrated a number of approaches to developing an automata theory that could provide insights into the processing of information in brainlike machines, making it accessible to readers with no more than a college freshman's knowledge of mathematics. The book introduced many readers to aspects of cybernetics-the study of computation and control in animal and machine. But by the mid-1960s, many workers abandoned the integrated study of brains and machines to pursue artificial intelligence (AI) as an end in itself-the programming of computers to exhibit some aspects of human intelligence, but with the emphasis on achieving some benchmark of performance rather than on capturing the mechanisms by which humans were themselves intelligent. Some workers tried to use concepts from AI to model human cognition using computer programs, but were so dominated by the metaphor "the mind is a computer" that many argued that the mind must share with the computers of the 1960s the property of being serial, of executing a series of operations one at a time. As the 1960s became the 1970s, this trend continued. Meanwhile, experi mental neuroscience saw an exploration of new data on the anatomy and physiology of neural circuitry, but little of this research placed these circuits in the context of overall behavior, and little was informed by theoretical con cepts beyond feedback mechanisms and feature detectors.

Four Colors Suffice - How the Map Problem Was Solved | Robin Wilson usato Scienze Matematica e Ingegneria

Four Colors Suffice - How the Map Problem Was Solved | Robin Wilson usato Scienze Matematica e Ingegneria

On October 23, 1852, Professor Augustus De Morgan wrote a letter to a colleague, unaware that he was launching one of the most famous mathematical conundrums in history--one that would confound thousands of puzzlers for more than a century. This is the amazing story of how the "map problem" was solved. The problem posed in the letter came from a former student: What is the least possible number of colors needed to fill in any map (real or invented) so that neighboring counties are always colored differently? This deceptively simple question was of minimal interest to cartographers, who saw little need to limit how many colors they used. But the problem set off a frenzy among professional mathematicians and amateur problem solvers, among them Lewis Carroll, an astronomer, a botanist, an obsessive golfer, the Bishop of London, a man who set his watch only once a year, a California traffic cop, and a bridegroom who spent his honeymoon coloring maps. In their pursuit of the solution, mathematicians painted maps on doughnuts and horseshoes and played with patterned soccer balls and the great rhombicuboctahedron. It would be more than one hundred years (and countless colored maps) later before the result was finally established. Even then, difficult questions remained, and the intricate solution--which involved no fewer than 1,200 hours of computer time--was greeted with as much dismay as enthusiasm. Providing a clear and elegant explanation of the problem and the proof, Robin Wilson tells how a seemingly innocuous question baffled great minds and stimulated exciting mathematics with far-flung applications. This is the entertaining story of those who failed to prove, and those who ultimately did prove, that four colors do indeed suffice to color any map. This new edition features many color illustrations. It also includes a new foreword by Ian Stewart on the importance of the map problem and how it was solved.

Secrets of Saffron - The vagabond life of the world's most seductive spice | Pat Willard usato Manualistica Piante Animali

Secrets of Saffron - The vagabond life of the world's most seductive spice | Pat Willard usato Manualistica Piante Animali

There are few words as evocative as saffron. Over thousands of years it has perfumed the halls of Crete's palaces, made Cleopatra more alluring, and driven crusaders and German peasants to their deaths. While spices that drove adventurers to the ends of the earth, such as cinnamon, mace, and ginger, have become commonplace, saffron remains tantalizingly exotic. Nothing more than the dried stamens of the autumn-flowering purple crocus, it might as well be fairy dust. Resistant to modern horticultural technology, the fragile blossoms must still be gathered by hand from the ancient fields of Iran, Greece, Italy, southern France, and Spain. Secrets of Saffron is the story of this extravagant rover. Guided with wit and assurance by acclaimed food writer Pat Willard, we roam the rich landscapes of history and personal memory. We dine in the heavenly gardens of Persia; bathe with Alexander the Great; are served golden swans at the medieval court of France. With Willard's help, we also discover the quiet comforts of saffron, from soups that have eased illness to pies that defy death, until we arrive at last in the present day at a small garden in Brooklyn. Told in sumptuous prose, complete with fabulous ancient and modern recipes—including a Moorish wedding feast, a luscious creme brulee, and a balm for an aching heart—Secrets of Saffron will awaken in you a voracious desire for the private pleasures of this most precious spice. "I am impressed by Pat Willard's singleminded devotion to one of my favorite subjects. I have been under saffron's spell for some time and it is an integral ingredient in my cooking. I love the romance of its noble and complicated history, as well as the painstaking process of cultivation." —Todd English, author of The Olives Dessert Table "Saffron, the haughtiest, most expensive, and most mysterious of spices, has found its rightful biographer in Pat Willard, who plumbs its historical, mythological, and psychological depths with illuminating insight and a richly evocative (and surprisingly personal) prose. For saffron lovers, this book is a necessary read; for those like myself who have previously equated that spice with such culinary esoterica as gold leaf flakes or wild fennel pollen, Secrets of Saffron is a revelation—and a highly enjoyable page-turner, as well." —John Thorne, author of Outlaw Cook and Pot on the Fire "An admiring account of an exotic spice with a long and varied history, by a food writer whose imagination keeps the story light and lively... a charming little gift for an inquisitive cook."—Kirkus Reviews
