Time for Aristotle

What is the relation between time and change? Does time depend on the mind? Is the present always the same or is it always different? Aristotle tackles these questions in the Physics, and Time for Aristotle is the first book in English devoted to this discussion.Aristotle claims that time is not a kind of change, but that it is something dependent on change; he defines it as a kind of 'number of change'. Ursula Coope argues that what this means is that time is a kind of order (not, as is commonly supposed, a kind of measure). It is universal order within which all changes are related to each other. This interpretation enables Coope to explain two puzzling claims that Aristotle makes: that the now is like a moving thing, and that time depends for itsexistence on the mind. Brilliantly lucid in its explanation of this challenging section of the Physics, Time for Aristotle shows his discussion to be of enduring philosophical interest.

God's Clockmaker

Richard of Wallingford and the Invention of Time

Author: John North

Publisher: Bloomsbury Publishing

ISBN: 0826439624

Category: History

Clocks became common in late medieval Europe and the measurement of time began to rule everyday life. God's Clockmaker is a biography of England's greatest medieval scientist, a man who solved major practical and theoretical problems to build an extraordinary and pioneering astronomical and astrological clock. Richard of Wallingford (1292-1336), the son of a blacksmith, was a brilliant mathematician with a genius for the practical solution of technical problems. Trained at Oxford, he became a monk and then abbot of the great abbey of St Albans, where he built his clock. Although as abbot he held great power, he was also a tragic figure, becoming a leper. His achievement, nevertheless, is a striking example of the sophistication of medieval science, based on knowledge handed down from the Greeks via the Arabs.

The Measure of All Things

The Seven-Year Odyssey and Hidden Error That Transformed the World

Author: Ken Alder

Publisher: Simon and Schuster

Page: 432

In June 1792, amidst the chaos of the French Revolution, two intrepid astronomers set out in opposite directions on an extraordinary journey. Starting in Paris, Jean-Baptiste-Joseph Delambre would make his way north to Dunkirk, while Pierre-François-André Méchain voyaged south to Barcelona. Their mission was to measure the world, and their findings would help define the meter as one ten-millionth of the distance between the pole and the equator—a standard that would be used “for all people, for all time.” The Measure of All Things is the astonishing tale of one of history’s greatest scientific adventures. Yet behind the public triumph of the metric system lies a secret error, one that is perpetuated in every subsequent definition of the meter. As acclaimed historian and novelist Ken Alder discovered through his research, there were only two people on the planet who knew the full extent of this error: Delambre and Méchain themselves. By turns a science history, detective tale, and human drama, The Measure of All Things describes a quest that succeeded as it failed—and continues to enlighten and inspire to this day.

The Measurement of Air Flow

Author: E. Ower,R. C. Pankhurst

Publisher: Elsevier

ISBN: 1483188043

Category: Technology & Engineering

Page: 376

View: 3987

The Measurement of Air Flow: 5th Edition (in SI Units) deals primarily with the measurement (expressed in SI units) of the speed of air in motion relative to solid boundaries or surfaces. The methods described apply not only to air flow but also to the flow of other gases with little, if any, modification, except as regards the numerical values of the various physical properties occurring in the equations. Furthermore, much of the theory applies to the flow of both liquids and gases. Comprised of 13 chapters, this volume begins with an overview of the general principles of the pressure-tube anemometer used in measuring pressure difference from which the speed of flow can be deduced. The reader is then introduced to the characteristics of pitot and static tubes in incompressible flow; pitot and static observations in compressible flow; and the flow of air in pipes of circular cross-section. Subsequent chapters focus on the measurement of incompressible flow in pipes by pitot and static traverse methods; methods of flow measurement based upon the rates of cooling of hot bodies; and the measurement of pulsating flow. This book is intended for students and engineers and for other practitioners concerned with the measurement of the speed of air flow.

Immigrants in the Lands of Promise

Italians in Buenos Aires and New York City, 1870 - 1914

Author: Michael Adas

Page: 452

Over the past five centuries, advances in Western understanding of and control over the material world have strongly influenced European responses to non-Western peoples and cultures. In Machines as the Measure of Men, Michael Adas explores the ways in which European perceptions of their scientific and technological superiority shaped their interactions with people overseas. Adopting a broad, comparative perspective, he analyzes European responses to the cultures of sub-Saharan Africa, India, and China, cultures that they judged to represent lower levels of material mastery and social organization. Beginning with the early decades of overseas expansion in the sixteenth century, Adas traces the impact of scientific and technological advances on European attitudes toward Asians and Africans and on their policies for dealing with colonized societies. He concentrates on British and French thinking in the nineteenth century, when, he maintains, scientific and technological measures of human worth played a critical role in shaping arguments for the notion of racial supremacy and the "civilizing mission" ideology which were used to justify Europe's domination of the globe. Finally, he examines the reasons why many Europeans grew dissatisfied with and even rejected this gauge of human worth after World War I, and explains why it has remained important to Americans. Showing how the scientific and industrial revolutions contributed to the development of European imperialist ideologies, Machines as the Measure of Men highlights the cultural factors that have nurtured disdain for non-Western accomplishments and value systems. It also indicates how these attitudes, in shaping policies that restricted the diffusion of scientific knowledge, have perpetuated themselves, and contributed significantly to chronic underdevelopment throughout the developing world. Adas's far-reaching and provocative book will be compelling reading for all who are concerned about the history of Western imperialism and its legacies. First published to wide acclaim in 1989, Machines as the Measure of Men is now available in a new edition that features a preface by the author that discusses how subsequent developments in gender and race studies, as well as global technology and politics, enter into conversation with his original arguments.

The Measure of Times Past

Pre-Newtonian Chronologies and the Rhetoric of Relative Time

Publisher: University of Chicago Press

ISBN: 9780226897226

Category: History

Page: 292

In this extraordinary work, Donald J. Wilcox seeks to discover an approach to narrative and history consistent with the discontinuous, relative time of the twentieth century. He shows how our B.C./A.D. system, intimately connected to Newtonian concepts of continuous, objective, and absolute time, has affected our conception and experience of the past. He demonstrates absolute time's centrality to modern historical methodologies and the problems it has created in the selection and interpretation of facts. Inspired by contemporary fiction and Einsteinian concepts of relativity, he concludes his analysis with a comparison of our system with earlier, pre-Newtonian time schemes to create a radical new critique of historical objectivity.

Measuring Time, Making History

Time is the crucial ingredient in history, and yet historians rarely talk about time as such. These essays offer new insight into the development of modern conceptions of time, from the Christian dating system (BC/AD or BCE/CE) to the idea of “modernity” as a new epoch in human history. Are the Gregorian calendar, world standard time, and modernity itself simply impositions of Western superiority? How did the idea of stages of history culminating in the modern period arise? Is time really accelerating? Can we—should we—try to move to a new chronological framework, one that reaches back to the origins of humans and forward away or beyond modernity? These questions go to the heart of what history means for us today. Time is now on the agenda.

The Mastery of Time

A History of Timekeeping, from the Sundial to the Wristwatch: Discoveries, Inventions, and Advances in Master Watchmaking

Author: Dominique Fléchon,Franco Cologni

More than a simple chronology, this volume explores the technical resources used to measure time--solar, hydraulic, mechanical, or electrical--just as it explains the key factors behind the major breakthroughs in the science of horology. From ancient astronomical observatories to atomic clocks, instruments for telling time have always been closely linked to the cutting-edge sciences of the day, ranging from medicine and navigation to aeronautics. Inventions in timekeeping have been crucial to the organization of human society and to activities such as farming, industry, and trade. Each new development was based on the needs and accomplishments of its day yet spurred further discoveries. Writing a history of time means viewing human genius through the prism of the steady mastery of a crucial technology. The patient, long-term conquest of accuracy has been the result of successive advances from sundial to wristwatch up to the recent exploits of the heirs to this age-old quest, namely master horologists of the twenty-first century.
