This book provides an accessible introduction to loop quantum gravity and some of its applications, at a level suitable for undergraduate students and others with only a minimal knowledge of college level physics. In particular it is not assumed that the reader is familiar with general relativity and only minimally familiar with quantum mechanics and Hamiltonian mechanics. Most chapters end with problems that elaborate on the text, and aid learning. Applications such as loop quantum cosmology, black hole entropy and spin foams are briefly covered. The text is ideally suited for an undergraduate course in the senior year of a physics major. It can also be used to introduce undergraduates to general relativity and quantum field theory as part of a 'special topics' type of course.
The Future of Aerospace
Author: National Academy of Engineering
Publisher: National Academies Press
Few technological advances have affected the lives and dreams of individuals and the operations of companies and governments as much as the continuing development of flight. From space exploration to package transport, from military transport to passenger helicopter use, from passenger jumbo jets to tilt-rotor commuter planes, the future of flying is still rapidly developing. The essays in this volume survey the state of progress along several fronts of this constantly evolving frontier. Five eminent authorities assess prospects for the future of rotary-wing aircraft, large passenger aircraft, commercial aviation, manned spaceflight, and defense aerospace in the post-Cold War era.

What is the relationship between democracy and critical thinking? What must a citizen in a democracy know to make the word democracy meaningful? In A Short Course in Intellectual Self-Defense, historian and educator Normand Baillargeon provides readers with the tools to see through the spin and jargon of everyday politics and news reporting in order to decide for themselves what is at stake and how to ask the necessary questions to protect themselves from the manipulations of the government and the media. Whether the issue be the call to what we’re told will be a bloodless war, the "debate" around Intelligent Design, or the meaning of a military expenditure, Baillargeon teaches readers to evaluate information and sort fact from official and media spin.
On Space and Time
Author: John Polkinghorne, Roger Penrose, Alain Connes, Michael Heller
Publisher: Cambridge University Press
Gets to the heart of science by asking a fundamental question: what is the true nature of space and time?
Author: Alan Sokal, Jean Bricmont
In 1996 physicist Alan Sokal published an essay in Social Text--an influential academic journal of cultural studies--touting the deep similarities between quantum gravitational theory and postmodern philosophy. Soon thereafter, the essay was revealed as a brilliant parody, a catalog of nonsense written in the cutting-edge but impenetrable lingo of postmodern theorists. The event sparked a furious debate in academic circles and made the headlines of newspapers in the U.S. and abroad. Now in Fashionable Nonsense: Postmodern Intellectuals' Abuse of Science, Sokal and his fellow physicist Jean Bricmont expand from where the hoax left off. In a delightfully witty and clear voice, the two thoughtfully and thoroughly dismantle the pseudo-scientific writings of some of the most fashionable French and American intellectuals. More generally, they challenge the widespread notion that scientific theories are mere "narrations" or social constructions.

Quantum gravity is the field of theoretical physics attempting to unify the theory of quantum mechanics, which describes three of the fundamental forces of nature, with general relativity, the theory of the fourth fundamental force: gravity. The ultimate goal is a unified framework for all fundamental forces -- a theory of everything. This book examines state-of-art research in this field.

Learn Python in One Hour
Author: Victor R. Volkman
Publisher: Modern Software Press
You?re already a smart person, you don?t need a 1000+ page book to get you started on the web?s fastest growing programming platform. Instead,ÿLearn Python in One Hourÿdelivers on the promise of code literacy while saving your most precious commodity ? time itself. Volkman?s innovative programming-by-example approach means you focus on usage, not mindless detail. Based on the author?s sold-out live seminars, you?ll see Python?s flexible coding technique in action as we refactor from script to procedural to object-oriented during actual problem solving. In a twelve-lesson progression, you?ll be exposed to this and more: Basic file input and output operations, incuding exceptions Using functions to compute and returnÿ multiple values Basic elements of a class definition and how to call methods Lists, dictionaries, sets, and other collections Iteration through collections, files, sorted sets Searching strings with regular expressions (regex) Client and server programs forÿREST methods Using threadsÿin Python for multiple tasks CGI-BIN programmingÿfor simple HTML Forms processing Six most common Python pitfalls Take the One Hour challenge and see if you too can pick up 90% of syntax and semantics in less time than you probably spend commuting each day. About the AuthorÿVictor R. Volkman graduatedÿcum laudeÿfrom Michigan Technological University with a BS in Computer Science in 1986. Since then, he has written for numerous publications, includingÿThe C Gazette, C++ Users Journal, Windows Developers Journal,ÿand many others. He has taught college-level programming courses at Washtenaw Community College and has served on its Computer Information Science (CIS) Faculty Advisory Board for more than a decade. Volkman says Python helped him "rediscover the joy of programming again." www.volkman.org FromÿModern Software Press
