In Timaeus Plato attempts to describe and explain the structure of the universe: the creator god, the elements, the lower gods, the stars, and men. The companion piece, Critias, is the origin of the story of Atlantis, the lost empire defeated by ancient Athenians. This is the clearest translation yet of these crucial ancient texts.

Written by Dr Alexandre Zagoskin, who is a Reader at Loughborough University, Quantum Mechanics: A Complete Introduction is designed to give you everything you need to succeed, all in one place. It covers the key areas that students are expected to be confident in, outlining the basics in clear jargon-free English, and then providing added-value features like summaries of key ideas, and even lists of questions you might be asked in your exam. The book uses a structure that is designed to make quantum physics as accessible as possible - by starting with its similarities to Newtonian physics, rather than the rather startling differences.

The next few decades will see a profound energy transformation throughout the world. By the end of the century (and perhaps sooner), we will shift from fossil fuel dependence to rely primarily on renewable sources like solar, wind, biomass, and geothermal power. Driven by the need to avert catastrophic climate change and by the depletion of easily accessible oil, coal, and natural gas, this transformation will entail a major shift in how we live. What might a 100% renewable future look like? Which technologies will play a crucial role in our energy future? What challenges will we face in this transition? And how can we make sure our new system is just and equitable?In Our Renewable Future, energy expert Richard Heinberg and scientist David Fridley explore the challenges and opportunities presented by the shift to renewable energy. Beginning with a comprehensive overview of our currenergy system, the authors survey issues of energy supply and demand in key sectors of the economy, including electricity generation, transportation, buildings, and manufacturing. In their detailed review of each sector, the authors examine the mcrucial challenges we face, from intermittency in fuel sources to energy storage and grid redesign. The book concludes with a discussion of energy and equity and a summary of key lessons and steps forward at the individual, community, and national level.The transition to clean energy will not be a simple matter of replacing coal with wind power or oil with solar; it will require us to adapt our energy usage as dramatically as we adapt our energy sources. Our Renewable Future is a clear-eyed and urgguide to this transformation that will be a crucial resource for policymakers and energy activists.

What are our obligations to others as people in a free society? Should government tax the rich to help the poor? Is the free market fair? Is it sometimes wrong to tell the truth? Is killing sometimes morally required? Is it possible, or desirable, to legislate morality? Do individual rights and the common good conflict? Michael J. Sandel's "e;Justice"e; course is one of the most popular and influential at Harvard. Up to a thousand students pack the campus theater to hear Sandel relate the big questions of political philosophy to the most vexing issues of the day, and this fall, public television will air a series based on the course. Justice offers readers the same exhilarating journey that captivates Harvard students. This book is a searching, lyrical exploration of the meaning of justice, one that invites readers of all political persuasions to consider familiar controversies in fresh and illuminating ways. Affirmative action, same-sex marriage, physician-assisted suicide, abortion, national service, patriotism and dissent, the moral limits of markets-Sandel dramatizes the challenge of thinking through these con?icts, and shows how a surer grasp of philosophy can help us make sense of politics, morality, and our own convictions as well. Justice is lively, thought-provoking, and wise-an essential new addition to the small shelf of books that speak convincingly to the hard questions of our civic life.

One of the greatest nineteenth-century scientist-explorers, Alexander von Humboldt traversed the tropical Spanish Americas between 1799 and 1804. By the time of his death in 1859, he had won international fame for his scientific discoveries, his observations of Native American peoples and his detailed descriptions of the flora and fauna of the 'new continent'. The first to draw and speculate on Aztec art, to observe reverse polarity in magnetism and to discover why America is called America, his writings profoundly influenced the course of Victorian culture, causing Darwin to reflect: 'He alone gives any notion of the feelings which are raised in the mind on first entering the Tropics'.

A groundbreaking textbook that explores the phenomena and physics of music and soundWhy You Hear What You Hear is the first book on the physics of sound for the nonspecialist to empower readers with a hands-on, ears-open approach that includes production, analysis, and perception of sound. The book makes possible a deep intuitive understanding of many aspects of sound, as opposed to the usual approach of mere description. This goal is aided by hundreds of original illustrations and examples, many of which the reader can reproduce and adjust using the same tools used by the author (e.g., very accessible applets for PC and Mac, and interactive web-based examples, simulations, and analysis tools that can be found on the book's website: whyyouhearwhatyouhear.com). Readers are positioned to build intuition by participating in discovery.This truly progressive introduction to sound engages and informs amateur and professional musicians, performers, teachers, sound engineers, students of many stripes, and indeed anyone interested in the auditory world. The book does not hesitate to follow entertaining and sometimes controversial side trips into the history and world of acoustics, reinforcing key concepts. You will discover how musical instruments really work, how pitch is perceived, and how sound can be amplified with no external power source.Sound is key to our lives, and is the most accessible portal to the vibratory universe. This book takes you there.The first book on sound to offer interactive tools, building conceptual understanding via an experiential approachSupplementary website (http://www.whyyouhearwhatyouhear.com) provides Java, MAX, and other free, multiplatform, interactive graphical and sound appletsExtensive selection of original exercises available on the web with solutionsNearly 400 full-color illustrations, many of simulations that students can do

The Gospel According to Spiritism is a splendid book - elegantly written, radiant in its prose, and a source of charm for the speculative imagination. The book celebrates Allan Kardec's discovery of the Christian message through the poetic longings and devotional confessions of those who have already crossed the great river. This is a book that invites the reader to ponder her or his life through the vivid accounts from those who have already mastered their lessons, and the reflections of those who were willing to reevaluate their own past experiences on Earth. This is what makes the Gospel a true guide for our own inner transformation, and for engaging the self in the discovery of each person's true purpose in life.

This is the first book to explore this scientific landscape from a broad spectrum of fields: from astronomy, genetics, linguistics, computing, history, and sociology to gender, media and literature studies.

A brilliant, sinuous exploration of family and childhood memory by one of the most original British philosophers of the twentieth century.Germs is about first things, the seeds from which a life grows, as well as about the illnesses it incurs, the damage it sustains. Written at the end of his life by Richard Wollheim, one of the major philosophers of the late twentieth century, the book is not the usual story of growing up and getting on but a brilliant recovery and evocation of childhood consciousness and unconsciousness, an eerily precise rendering of that primitive, formative world we all come from in which we do not know either the world or ourselves for sure, and things—houses, clothes, meals, parents—loom large around us, as indispensable as they are out of our control. Richard Wollheim’s remarkably original memoir is a disturbing, enthralling, dispassionate but also deeply personal depiction of a child standing, fascinated and fearful, on the threshold of individual life.
