Prime Obsession taught us not to be afraid to put the math in a math book. Unknown Quantity heeds the lesson well. So grab your graphing calculators, slip out the slide rules, and buckle up! John Derbyshire is introducing us to algebra through the ages-and it promises to be just what his die-hard fans have been waiting for. "Here is the story of algebra." With this deceptively simple introduction, we begin our journey. Flanked by formulae, shadowed by roots and radicals, escorted by an expert who navigates unerringly on our behalf, we are guaranteed safe passage through even the most treacherous mathematical terrain. Our first encounter with algebraic arithmetic takes us back 38 centuries to the time of Abraham and Isaac, Jacob and Joseph, Ur and Haran, Sodom and Gomorrah. Moving deftly from Abel's proof to the higher levels of abstraction developed by Galois, we are eventually introduced to what algebraists have been focusing on during the last century. As we travel through the ages, it becomes apparent that the invention of algebra was more than the start of a specific discipline of mathematics-it was also the birth of a new way of thinking that clarified both basic numeric concepts as well as our perception of the world around us. Algebraists broke new ground when they discarded the simple search for solutions to equations and concentrated instead on abstract groups. This dramatic shift in thinking revolutionized mathematics. Written for those among us who are unencumbered by a fear of formulae, Unknown Quantity delivers on its promise to present a history of algebra. Astonishing in its bold presentation of the math and graced with narrative authority, our journey through the world of algebra is at once intellectually satisfying and pleasantly challenging.

Published in 1999, this work sets out to give an account of explanation which is adequate to the problems that arise when looking at physical science. It offers a theory of explanation with supporting analysis, and also an application to the task of giving an account of explanation in quantum mechanics.

This classic set of essays by Nobel Laureate and leading monetary theorist Milton Friedman presents a coherent view of the role of money, focusing on specific topics related to the empirical analysis of monetary phenomena and policy. The early chapters cover factors determining the real quantity of money held in a community and the welfare implications of policies that affect the quantity held. The following chapters formally restate why quantity analysis has become central to the science of economics. Friedman's presidential address to the American Economic Association, included here, provides a general summary of his views on the role of monetary policy, with an emphasis on its limitations and its possibilities. This theoretical framework is used in examining a number of empirical problems: the demand for money, the explanation of price changes in wartime periods, and the role of money in business cycles. These essays summarize some of the most important results of Friedman's extensive research over the course of his lifetime. The chapters on policy that follow survey the positions of earlier economists and deal with the importance of lags and the implications of destabilizing speculation in foreign markets. Taken as a whole, The Optimum Quantity of Money provides a comprehensive view of the body of monetary theory developed in leading centers of monetary analysis. This work is essential reading for economists and graduate students in the field. The volume will be no less important for practicing business and banking personnel as well. The new statement by Michael Bordo, a student of Friedman's and an expert in the field, provides a sense of where the field now stands in the economy and academy. Milton Friedman is a senior fellow at the Hoover Institution of Stanford University. Before that, he was Distinguished Service Professor of Economics at the University of Chicago. He has also taught at Columbia University, the University of Wisconsin, the University of Minnesota, and Cambridge University. Among his many books are Essays in Positive Economics, A Program for Monetary Stability, Capitalism and Freedom, and A Monetary History of the United States. Michael D. Bordo is professor of economics at Rutgers, The State University of New Jersey, and author, with Lars Jonung, of, among other works, Demand for Money.

This book, first published in 2001, is an account of eugenicists' efforts to improve the inherited biological quality of the French population.

The third edition of the Quantity Surveyor’s Pocket Book has been updated in line with NRM1, NRM2 and NRM3, and remains a must-have guide for students and qualified practitioners. Its focused coverage of the data, techniques and skills essential to the quantity surveying role makes it an invaluable companion for everything from initial cost advice to the final account stage. Key features and updates included in this new edition: an up-to-date analysis of NRM1, 2 and 3; measurement and estimating examples in NRM2 format; changes in procurement practice; changes in professional development, guidance notes and schemes of work; the increased use of NEC3 form of contract; the impact of BIM. This text includes recommended formats for cost plans, developer’s budgets, financial reports, financial statements and final accounts. This is the ideal concise reference for quantity surveyors, project and commercial managers, and students of any of the above.

The first IUPAC Manual of Symbols and Terminology for Physicochemical Quantities and Units (the Green Book) of which this is the direct successor, was published in 1969, with the object of 'securing clarity and precision, and wider agreement in the use of symbols, by chemists in different countries, among physicists, chemists and engineers, and by editors of scientific journals'. Subsequent revisions have taken account of many developments in the field, culminating in the major extension and revision represented by the 1988 edition under the simplified title Quantities, Units and Symbols in Physical Chemistry. This 2007, Third Edition, is a further revision of the material which reflects the experience of the contributors with the previous editions. The book has been systematically brought up to date and new sections have been added. It strives to improve the exchange of scientific information among the readers in different disciplines and across different nations. In a rapidly expanding volume of scientific literature where each discipline has a tendency to retreat into its own jargon this book attempts to provide a readable compilation of widely used terms and symbols from many sources together with brief understandable definitions. This is the definitive guide for scientists and organizations working across a multitude of disciplines requiring internationally approved nomenclature.

What is there is only a limited amount of sanity in the world and the real reason people go mad is because somebody has to? What if a mysterious tribe in the Amazon rainforest turn out to be the most boring people on earth? What if the afterlife is nothing more than a London suburb, where the dead get new flats, new jobs, and their own telephone directory? These are the sort of truths that emerge in this collection of stories by one of England's most gifted writers. In The Quantity Theory of Insanity, Will Self tips over the banal surfaces of everyday existence to uncover the hideous, the hilarious, and the bizarre. Psychiatry, anthropology, theology—and literature—will never be the same.

This unique approach to intermediate microeconomics reverses the standard order of topics, provides examples and solved practice problems.
