'If you think you understand AI and all of the related issues, you don't. By the time you finish this exceptionally lucid and riveting book you will breathe more easily and wisely' - Michael Gazzaniga A leading computer scientist brings human sense to the AI bubble No recent scientific enterprise has been so alluring, terrifying and filled with extravagant promise and frustrating setbacks as artificial intelligence. Writing with clarity and passion, leading AI researcher Melanie Mitchell offers a captivating account of modern-day artificial intelligence. Flavoured with personal stories and a twist of humour, Artificial Intelligence illuminates the workings of machines that mimic human learning, perception, language, creativity and common sense. Weaving together advances in AI with cognitive science and philosophy, Mitchell probes the extent to which today's 'smart' machines can actually think or understand, and whether AI even requires such elusive human qualities at all. Artificial Intelligence: A Guide for Thinking Humans provides readers with an accessible and clear-eyed view of the AI landscape, what the field has actually accomplished, how much further it has to go and what it means for all of our futures.

The ?rst and foremost goal of this lecture series was to show the beauty, depth and usefulness of the key ideas in computer science. While working on the lecture notes, we came to understand that one can recognize the true spirit of a scienti?c discipline only by viewing its contributions in the framework of science as a whole. We present computer science here as a fundamental science that, interacting with other scienti?c disciplines, changed and changes our view on the world, that contributes to our understanding of the fundamental concepts of science and that sheds new light on and brings new meaning to several of these concepts. We show that computer science is a discipline that discovers spectacular, unexpected facts, that ?nds ways out in seemingly unsolvable s- uations, and that can do true wonders. The message of this book is that computer science is a fascinating research area with a big impact on the real world, full of spectacular ideas and great ch- lenges. It is an integral part of science and engineering with an above-average dynamic over the last 30 years and a high degree of interdisciplinarity. The goal of this book is not typical for popular science writing, whichoftenrestrictsitselftooutliningtheimportanceofaresearch area. Whenever possible we strive to bring full understanding of the concepts and results presented.

R419 R351 Discovery Miles 3 510 Save R68 (16%) Ships in 10 - 15 working days

Why do some people like a certain aroma and others hate it? Is smell personal or cultural? How does it affect our choices and our actions?

The Scent of Desire is the definitive psychological study of the importance of smell in our lives, from nourishment to procreation to our relationships with other people and the world at large. Located in the same part of the brain that processes emotion, memory, and motivation, this most essential of senses is imperative to our physical and emotional well-being. It was crucial to our ancestors' existence and it remains so today, profoundly shaping our emotional, physical, and even sexual lives.

One of the world's leading experts on the psychology of smell, Rachel Herz investigates how smell functions, what purpose it serves, and how inextricably it is linked to our survival in this compelling, surprising, delightfully informative appreciation of the wonders of this sadly neglected sense.

From simple reflexes to complex choreographies of movement, all animal behavior is governed by a nervous system. But what kind of government is it-a dictatorship or a democracy? Nervous systems consist of circuits of interconnected nerve cells (neurons) that transmit and receive information via electrical signals. Every moment, each neuron adds up stimulating and inhibiting inputs from many other neurons to determine whether to send an electrical signal to its recipients. Some circuits are dominated by a single "dictator" neuron that gathers information from many sources and then issues commands, such as the Mauthner neuron that triggers escape in fish. In other more "democratic" circuits, such as those mediating eye movements in monkeys, the outcome is determined by a tally of "votes" from a large population of neurons. Rhythmic movements like breathing and locomotion are generated by "government programs" within the central nervous system, but modified by a soup of chemicals and by free market-like feedback from sensory neurons. Nervous systems also use sophisticated surveillance of the surrounding environment and keep track of their own decisions in order to avoid internal conflicts. Nervous systems are not restricted to using one set of procedures at a time. They have evolved over long periods to control behaviors in whichever ways are most effective, and they essentially combine multiple forms of government simultaneously. Engaging and accessible, Governing Behavior explains the variety of structures and strategies that control behavior, while providing an overview of thought-provoking debates and cutting-edge research in neurobiology.

At first glance, the worlds of math and the arts might not seem like comfortable neighbors. But as mathematician John D. Barrow points out, they have a strong and natural affinity-after all, math is the study of all patterns, and the world of the arts is rich with pattern. Barrow whisks us through 100 thought-provoking and often whimsical intersections between math and many arts, from the golden ratios of Mondrian's rectangles and the curious fractal-like nature of Pollock's drip paintings to ballerinas' gravity-defying leaps and the next generation of monkeys on typewriters tackling Shakespeare. For those of us with our feet planted more firmly on the ground, Barrow also wields everyday equations to reveal how many guards are needed in an art gallery or where you should stand to look at sculptures. From music and drama to literature and the visual arts, Barrow's witty and accessible observations are sure to spark the imaginations of math nerds and art aficionados alike.

Coronavirus, AIDS, and Ebola: Viruses are normally defined as pathogens. Most viruses are, however, not enemies or killers. Well-known virologist and cancer researcher Karin Moelling describes surprising insights about a completely new and unexpected world of viruses. Viruses are ubiquitous, in the oceans, our environment, in animals, plants, bacteria, in our body, even in our genomes. They influence our weather, can contribute to control obesity, and can surprisingly be applied against threatening multi-resistant bacteria. The success story of the viruses started more than 3.5 billion years ago in the dawn of life when even cells did not exist. They are the superpower of life. There are more viruses on earth than stars in the sky. Viruses are everywhere. Some of them are incredibly ancient. Many viruses are hundredfold smaller than bacteria, but others are tenfold bigger and they were discovered only recently - the giant viruses, even deep within the permafrost where they were reactivated after 30,000 years.The author talks about a completely new world of viruses, which are based on the most recent, in part her own research results. Could viruses have been our oldest ancestors? Have viruses even 'invented' social behavior, do they lead to geniuses such as Mozart or Einstein - or alternatively to cancer? They can help to cure cancer. In this book, the author made a clear distinction between what is fact and what is her vision. This book is written for a general audience and not just for the experts. Its aim is to stimulate thinking, and perhaps to attract more young scientists to enter this field of research.This revised edition is brought up to date by a new chapter on the SARS-CoV-2 pandemic.

Some have seen philosophy embedded in episodes of The Simpsons; others have detected elements of psychology and religion. Simon Singh, bestselling author of Fermat's Last Theorem, The Code Book and The Big Bang, instead makes the compelling case that what The Simpsons' writers are most passionate about is mathematics. He reveals how the writers have drip-fed morsels of number theory into the series over the last twenty-five years; indeed, there are so many mathematical references in The Simpsons, and in its sister program, Futurama, that they could form the basis of an entire university course. Using specific episodes as jumping off points - from 'Bart the Genius' to 'Treehouse of Horror VI' - Simon Singh brings to life the most intriguing and meaningful mathematical concepts, ranging from pi and the paradox of infinity to the origins of numbers and the most profound outstanding problems that haunt today's generation of mathematicians. In the process, he introduces us to The Simpsons' brilliant writing team - the likes of Ken Keeler, Al Jean, Jeff Westbrook, and Stewart Burns - who are not only comedy geniuses, but who also hold advanced degrees in mathematics.This eye-opening book will give anyone who reads it an entirely new mathematical insight into the most successful show in television history.

Whether it's arguing about the moon landing hoax or a Frisbee-like Earth drifting through space, when held up to science and critical thinking, these ideas fall flat. In Weird Earth: Debunking Strange Ideas About Our Planet, Donald R. Prothero demystifies these conspiracies and offers answers to some of humanity's most outlandish questions. Applying his extensive scientific knowledge, Prothero corrects misinformation that con artists and quacks use to hoodwink others about geology-hollow earth, expanding earth, and bizarre earthquakes-and mystical and paranormal happenings-healing crystals, alien landings, and the gates of hell. By deconstructing wild claims such as prophesies of imminent natural disasters, Prothero provides a way for everyone to recognize dubious assertions. Prothero answers these claims with facts, offering historical and scientific context in a light-hearted manner that is accessible to everyone, no matter their background. With a careful layering of evidence in geology, archaeology, and biblical and historical records, Prothero's Weird Earth examines each conspiracy and myth and leaves no question unanswered.

Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world. Like every other species, we humans are here by accident. But it is shocking just how many things-any of which might never have occurred-had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death. This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.

However in the modern world it often feels as though we have completely removed boredom from our lives; we are addicted to our phones, we reply to our emails twenty-four hours a day, tweet as we watch TV, watch TV as we commute, check Facebook as we walk and Instagram while we eat. Constant stimulation has become our default mode. In this easy to follow, practical book, award-winning journalist Manoush Zomorodi explores the connection between boredom and original thinking, and will show you how to ditch your screens and start embracing time spent doing nothing. Spark will help you unlock the way to becoming your most productive and creative self. 'Full of easy steps to make each day more effective' - Charles Duhigg, author of The Power of Habit
