As a student and young researcher in the 1980s, Gelernter hoped to build a program with a dial marked "focus." At maximum "focus," the program would "think" rationally, formally, reasonably. As the dial was turned down and "focus" diminished, its "mind" would start to wander, and as you dialed even lower, this artificial mind would start to free-associate, eventually ignoring the user completely as it cruised off into the mental adventures we know as sleep.While the program was a only a partial success, it laid the foundation for The Tides of Mind, a groundbreaking new exploration of the human psyche that shows us how the very purpose of the mind changes throughout the day. Indeed, as Gelernter explains, when we are at our most alert, when reasoning and creating new memories is our main mental business, the mind is a computer-like machine that keeps emotion on a short leash and attention on our surroundings. As we gradually tire, however, and descend the "mental spectrum," reasoning comes unglued. Memory ranges more freely, the mind wanders, and daydreams grow more insistent. Self-awareness fades, reflection blinks out, and at last we are completely immersed in our own minds.With far-reaching implications, Gelernter’s landmark "Spectrum of Consciousness" finally helps decode some of the most mysterious wonders of the human mind, such as the numinous light of early childhood, why dreams are so often predictive, and why sadism and masochism underpin some of our greatest artistic achievements. It’s a theory that also challenges the very notion of the mind as a machine—and not through empirical studies or "hard science" but by listening to our great poets and novelists, who have proven themselves as humanity's most trusted guides to the subjective mind and inner self.In the great introspective tradition of Wilhelm Wundt and René Descartes, David Gelernter promises to not only revolutionize our understanding of what it means to be human but also to help answer many of our most fundamental questions about the origins of creativity, thought, and consciousness.

    But, twenty years later, he fell in love and he now presents one of the world's most popular science podcasts. Every year he meets hundreds of the world's greatest thinkers.In this erudite and witty book, Robin reveals why scientific wonder isn't just for the professionals. Filled with interviews featuring astronauts, comedians, teachers, quantum physicists, neuroscientists and more - as well as charting Robin's own journey with science - The Importance of Being Interested explores why many wrongly think of the discipline as distant and difficult. From the glorious appeal of the stars above to why scientific curiosity can encourage much needed intellectual humility, this optimistic and profound book will leave you filled with a thirst for intellectual adventure.

    

    It has been developed in response to the need for a text that supports the mastery of this difficult subject. Therefore, in addition to presenting electromagnetics in a concise and logical manner, the text includes end-of-section review questions, worked examples, boxed remarks that alert students to key ideas and tricky points, margin notes, and point-by-point chapter summaries. Examples and applications invite students to solve problems and build their knowledge of electromagnetics. Application topics include: electric motors, transmission lines, waveguides, antenna arrays and radar systems.

    He shows that freedom of choice isn't nearly enough. To be free, we must also be able to navigate life. People often need something like a GPS device to help them get where they want to go--whether the issue involves health, money, jobs, children, or relationships.In both rich and poor countries, citizens often have no idea how to get to their desired destination. That is why they are unfree. People also face serious problems of self-control, as many of them make decisions today that can make their lives worse tomorrow. And in some cases, we would be just as happy with other choices, whether a different partner, career, or place to live--which raises the difficult question of which outcome best promotes our well-being.Accessible and lively, and drawing on perspectives from the humanities, religion, and the arts, as well as social science and the law, On Freedom explores a crucial dimension of the human condition that philosophers and economists have long missed--and shows what it would take to make freedom real.

    

    Traces the history of time from Augustine's suggestion that there is no time, to the flowing time of Newton, the static time of Einstein, and then back, to the idea that there is no time in quantum gravity.

    Starting a war 'to promote freedom and democracy' could in certain though rare circumstances be a justified act; but in the case of the Second Gulf War that began in 2003, which involved reacting to criminals hiding in one country (Al Qaeda in Afghanistan or Pakistan) by invading another country (Iraq), one of the main fronts has, dismayingly, been the home front, where the War on Terror takes the form of a War on Civil Liberties in the spurious name of security. To defend 'freedom and democracy', Western governments attack and diminish freedom and democracy in their own country. By this logic, someone will eventually have to invade the US and UK to restore freedom and democracy to them.'In this lucid and timely book, Grayling sets out what's at risk, engages with the arguments for and against examining the cases made by Isaiah Berlin and Ronald Dworkin on the one hand, and Roger Scruton and John Gray on the other, and finally proposes a different way to respond that makes defending the civil liberties on which western society is founded the cornerstone for defeating terrorism.

    Tender and joyous, it is a celebration of art's power to transform the darkest of human experience and give voice to the grandest of human hopes.

    

    Soon Gen Xers will be the only cohort of Americans who remember life as it was lived before the arrival of the Internet. They are, as Hennessey dubs them, “the last adult generation,” the sole remaining link to a time when childhood was still a bit dangerous but produced adults who were naturally resilient. More than a decade into the social media revolution, the American public is waking up to the idea that the tech sector’s intentions might not be as pure as advertised. The mountains of money being made off our browsing habits and purchase histories are used to fund ever-more extravagant and utopian projects that, by their very natures, will corrode the foundations of free society, leaving us all helpless and digitally enslaved to an elite crew of ultra-sophisticated tech geniuses. But it’s not too late to turn the tide. There’s still time for Gen X to write its own future. A spirited defense of free speech, eye contact, and the virtues of patience, Zero Hour for Gen X is a cultural history of the last 35 years, an analysis of the current social and historical moment, and a generational call to arms.

    

    

    You'll discover how the sun shines, why light is both a wave and a particle, the certainty of the Uncertainty Principle, Schrodinger's Cat, Einstein's spooky action, how to build a quantum computer, and why quantum mechanics drives even its experts completely crazy. 'Jim Al-Khalili has done an admirable job of condensing the ideas of quantum physics from Max Planck to the possibilities of quantum computers into brisk, straightforward English' The Times

    Included in this collection are* William McEwan, a virologist, discussing his research into the biology of antiviral immunity* Naomi Eisenberger, a neuroscientist, wondering how social rejection affects us physically* Jon Kleinberg, a computer scientist, showing what massive datasets can teach us about society and ourselves* Anthony Aguirre, a physicist, who gives readers a tantalizing glimpse of infinity"Future Science shares with the world a delightful secret that we academics have been keeping--that despite all the hysteria about how electronic media are dumbing down the next generation, a tidal wave of talent has been flooding into science, making their elders feel like the dumb ones. . . . It has a wealth of new and exciting ideas, and will help shake up our notions regarding the age, sex, color, and topic clich�s of the current public perception of science."--Steven Pinker, author of The Stuff of Thought
