FULL COLOR. 2nd Edition. 124 pages. A new way to understand relativity. Covers relativity from the simplest everyday situations, by easy stages, to more complex topics. There are lots of 'real-life' examples, illustrations and diagrams. All math is kept simple and fully explained. Some surprises await on relativity matters usually considered difficult to understand, but which are, in fact, Relatively Simple. Theoretical analysis includes: Basic Relativity; Starlight Aberration; Simultaneity; Ring Lasers; Galaxy Rotation and Pioneer 10 anomalous acceleration.

'Outstanding Academic Title for 2014' by CHOICEEinstein Relatively Simple brings together for the first time an exceptionally clear explanation of both special and general relativity. It is for people who always wanted to understand Einstein's ideas but never thought they could.Told with humor, enthusiasm, and rare clarity, this entertaining book reveals how a former high school drop-out revolutionized our understanding of space and time. From E=mc2 and everyday time travel to black holes and the big bang, Einstein Relatively Simple takes us all, regardless of our scientific backgrounds, on a mind-boggling journey through the depths of Einstein's universe. Along the way, we track Einstein through the perils and triumphs of his life — follow his thinking, his logic, and his insights — and chronicle the audacity, imagination, and sheer genius of the man recognized as the greatest scientist of the modern era.In Part I on special relativity we learn how time slows and space shrinks with motion, and how mass and energy are equivalent. Part II on general relativity reveals a cosmos where black holes trap light and stop time, where wormholes form gravitational time machines, where space itself is continually expanding, and where some 13.7 billion years ago our universe was born in the ultimate cosmic event — the Big Bang.

This book provides a synthesis of Wierzbicka's theory of meaning, which is based on conceptual primitives and semantic universals, using empirical findings from a wide range of languages. While addressed primarily to linguists, the book deals with highly topical and controversial issues of central importance to several disciplines, including anthropology, psychology, and philosophy. - ;Conceptual primitives and semantic universals are the cornerstones of a semantic theory which Anna Wierzbicka has been developing for many years. Semantics: Primes and Universals is a major synthesis of her work, presenting a full and systematic exposition of that theory in a non-technical and readable way. It delineates a full set of universal concepts, as they have emerged from large-scale investigations across a wide range of languages undertaken by the author and her colleagues. On the basis of empirical cross-linguistic studies it vindicates the old notion of the 'psychic unity of mankind', while at the same time offering a framework for the rigorous description of different languages and cultures. - ;A major synthesis of Anna Wierzbicka's work -

For decades, the primary argument in justifying education has been based on its direct economic effects. Yet education also provides "social benefits" for individuals and society at large, including a better way of taking care of ourselves, and consequently creating a better society to live in. Though it is difficult to quantify these social benefits, a more systematic analysis would improve our understanding of the full effects of education and provide a basis for considering related policies. The Office of Research of the United States Department of Education commissioned a series of papers on measuring these effects of education. Those papers, revised and updated, are collected here. Kenneth J. Arrow provides perspective on education and preference formation, and Jere R. Behrman considers general conceptual and measurement issues in assessing the social benefits of education and policies related to education. These issues are taken up by experts in four fields--health, parenting, the environment, and crime. Themes addressed include measurement issues regarding what we mean by education and its benefits; basic analytical issues in assessing the impact of education on these social benefits using behavioral data; and whether the social benefits of education justify public policy interventions. Jere R. Behrman is William R. Kenan Jr. Professor of Economics, University of Pennsylvania. Nevzer G. Stacey is Senior Research Analyst, Office of Educational Research, U.S. Department of Education.

This in-depth resource teaches you to craft mechanics that generate challenging, enjoyable, and well-balanced gameplay. You’ll discover at what stages to prototype, test, and implement mechanics in games and learn how to visualize and simulate game mechanics in order to design better games. Along the way, you’ll practice what you’ve learned with hands-on lessons. A free downloadable simulation tool developed by Joris Dormans is also available in order to follow along with exercises in the book in an easy-to-use graphical environment. In Game Mechanics: Advanced Game Design, you’ll learn how to: * Design and balance game mechanics to create emergent gameplay before you write a single line of code. * Visualize the internal economy so that you can immediately see what goes on in a complex game. * Use novel prototyping techniques that let you simulate games and collect vast quantities of gameplay data on the first day of development. * Apply design patterns for game mechanics—from a library in this book—to improve your game designs. * Explore the delicate balance between game mechanics and level design to create compelling, long-lasting game experiences. * Replace fixed, scripted events in your game with dynamic progression systems to give your players a new experience every time they play. "I've been waiting for a book like this for ten years: packed with game design goodness that tackles the science without undermining the art." --Richard Bartle, University of Essex, co-author of the first MMORPG “Game Mechanics: Advanced Game Design by Joris Dormans & Ernest Adams formalizes game grammar quite well. Not sure I need to write a next book now!” -- Raph Koster, author of A Theory of Fun for Game Design.

There are many theoretical approaches to modelling forest systems, but not all of them have valid practical applications. This book reviews current thinking on various models and presents applications in various contexts. Papers have been selected and developed from those presented at aworkshop held in Portugal in June 2002. Topics covered include: Forest reality and modelling strategies Mathematical approaches and reasoning Estimation processes Models, validation and decision under uncertainty Model archives and metadata
