Book Description
This book develops the thesis that structure and function in a variety of condensed systems - from the atomic assemblies in inorganic frameworks and organic molecules, through molecular self-assemblies to proteins - can be unified when curvature and surface geometry are taken together with molecular shape and forces. An astonishing variety of synthetic and biological assemblies can be accurately modelled and understood in terms of hyperbolic surfaces, whose richness and beauty are only now being revealed by applied mathematicians, physicists, chemists and crystallographers. These surfaces, often close to periodic minimal surfaces, weave and twist through space, carving out interconnected labyrinths whose range of topologies and symmetries challenge the imaginative powers.The book offers an overview of these structures and structural transformations, convincingly demonstrating their ubiquity in covalent frameworks from zeolites used for cracking oil and pollution control to enzymes and structural proteins, thermotropic and lyotropic bicontinuous mesophases formed by surfactants, detergents and lipids, synthetic block copolymer and protein networks, as well as biological cell assemblies, from muscles to membranes in prokaryotic and eukaryotic cells. The relation between structure and function is analysed in terms of the previously neglected hidden variables of curvature and topology. Thus, the catalytic activity of zeolites and enzymes, the superior material properties of interpenetrating networks in microstructured polymer composites, the transport requirements in cells, the transmission of nerve signals and the folding of DNA can be more easily understood in the light of this.The text is liberally sprinkled with figures and colour plates, making it accessible to both the beginning graduate student and researchers in condensed matter physics and chemistry, mineralogists, crystallographers and biologists.

Book Description
“We have been given a powerful and often uplifting vision of what it is to be truly human.” —John Cottingham, The Tablet In seminal works ranging from Sources of the Self to A Secular Age, Charles Taylor has shown how we create possible ways of being, both as individuals and as a society. In his new book setting forth decades of thought, he demonstrates that language is at the center of this generative process. For centuries, philosophers have been divided on the nature of language. Those in the rational empiricist tradition—Hobbes, Locke, Condillac, and their heirs—assert that language is a tool that human beings developed to encode and communicate information. In The Language Animal, Taylor explains that this view neglects the crucial role language plays in shaping the very thought it purports to express. Language does not merely describe; it constitutes meaning and fundamentally shapes human experience. The human linguistic capacity is not something we innately possess. We first learn language from others, and, inducted into the shared practice of speech, our individual selves emerge out of the conversation. Taylor expands the thinking of the German Romantics Hamann, Herder, and Humboldt into a theory of linguistic holism. Language is intellectual, but it is also enacted in artistic portrayals, gestures, tones of voice, metaphors, and the shifts of emphasis and attitude that accompany speech. Human language recognizes no boundary between mind and body. In illuminating the full capacity of “the language animal,” Taylor sheds light on the very question of what it is to be a human being.

Book Description
An instant New York Times Bestseller! “Unreasonably entertaining . . . reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning.” —The New York Times From the New York Times-bestselling author of How Not to Be Wrong—himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything. How should a democracy choose its representatives? How can you stop a pandemic from sweeping the world? How do computers learn to play Go, and why is learning Go so much easier for them than learning to read a sentence? Can ancient Greek proportions predict the stock market? (Sorry, no.) What should your kids learn in school if they really want to learn to think? All these are questions about geometry. For real. If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word "geometry"comes from the Greek for "measuring the world." If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. Shape shows us how.

Book Description
Our ability to speak, write, understand speech and read is critical to our ability to function in today's society. As such, psycholinguistics, or the study of how humans learn and use language, is a central topic in cognitive science. This comprehensive handbook is a collection of chapters written not by practitioners in the field, who can summarize the work going on around them, but by trailblazers from a wide array of subfields, who have been shaping the field of psycholinguistics over the last decade. Some topics discussed include how children learn language, how average adults understand and produce language, how language is represented in the brain, how brain-damaged individuals perform in terms of their language abilities and computer-based models of language and meaning. This is required reading for advanced researchers, graduate students and upper-level undergraduates who are interested in the recent developments and the future of psycholinguistics.

""Reading this volume transported me back to Harvard and MIT lecture halls of the 1960s, where weekly Roman Jakobson would spellbind his audience (this reviewer included), developing his vision of language through impassioned exposition, deft and devastating allusions to critical literature, anecdotes with the force of parables, metaphors of mythic imagery, and above all else overriding verbal artistry: truly in his own phrase, 'In the poetry of grammar'.

Book Description
With a lot of recent developments in the field, this much-needed book has come at just the right time. It covers a variety of topics related to preserving and enhancing shape information at a geometric level. The contributors also cover subjects that are relevant to effectively capturing the structure of a shape by identifying relevant shape components and their mutual relationships.

Book Description
Japanese has a term that covers both green and blue. Russian has separate terms for dark and light blue. Does this mean that Russians perceive these colors differently from Japanese people? Does language control and limit the way we think? This short, opinionated book addresses the Sapir-Whorf hypothesis, which argues that the language we speak shapes the way we perceive the world. Linguist John McWhorter argues that while this idea is mesmerizing, it is plainly wrong. It is language that reflects culture and worldview, not the other way around. The fact that a language has only one word for eat, drink, and smoke doesn't mean its speakers don't process the difference between food and beverage, and those who use the same word for blue and green perceive those two colors just as vividly as others do. McWhorter shows not only how the idea of language as a lens fails but also why we want so badly to believe it: we're eager to celebrate diversity by acknowledging the intelligence of peoples who may not think like we do. Though well-intentioned, our belief in this idea poses an obstacle to a better understanding of human nature and even trivializes the people we seek to celebrate. The reality -- that all humans think alike -- provides another, better way for us to acknowledge the intelligence of all peoples.
