Robert Mayer And The Conservation Of Energy

The principle of the conservation of energy was among the most important developments of nineteenth-century physics, and Robert Mayer, a physician from a small city in Germany, was one of its codiscoverers. As ship's doctor on a voyage to the Dutch East Indies in 1840, Mayer noticed that the venous blood he let from a European seaman was lighter than he expected. This observation set off a train of reflections that led him first to conclude that there must be a quantitative relationship between heat and "motion" and then, over several years, to believe in the indestructibility and uncreatability of "force." Rejecting the commonly invoked influence of Naturphilosophie, Kenneth Caneva provides a rich historical context for the problems and issues that concerned Mayer and for the ways in which he gradually came to understand what became known as the conservation of energy. Demonstrating that the development of Mayer's thinking was fostered by a constant search for analogies, Caneva also analyzes the transformation of the life sciences in mid-century Germany and offers a major reevaluation of the status of the "vital force" during that period. The intellectual environment treated here embraces medicine, physiology, physics, chemistry, religion, and spiritualism. Kenneth L. Caneva is Associate Professor of History at the University of North Carolina, Greensboro. Originally published in 1993. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

An examination of the sources Helmholtz drew upon for his formulation of the conservation of energy and the impact of his work on nineteenth-century physics. In 1847, Herman Helmholtz, arguably the most important German physicist of the nineteenth century, published his formulation of what became known as the conservation of energy--unarguably the most important single development in physics of that century, transforming what had been a conglomeration of separate topics into a coherent field unified by the concept of energy. In Helmholtz and the Conservation of Energy, Kenneth Caneva offers a detailed account of Helmholtz's work on the subject, the sources that he drew upon, the varying responses to his work from scientists of the era, and the impact on physics as a discipline. Caneva describes the set of abiding concerns that prompted Helmholtz's work, including his rejection of the idea of a work-performing vital force, and investigates Helmholtz's relationship to both an older generation of physicists and an emerging community of reformist physiologists. He analyzes Helmholtz's indebtedness to Johannes Müller and Justus Liebig and discusses Helmholtz's tense and ambivalent relationship to the work of Robert Mayer, who had earlier proposed the uncreatability, indestructibility, and transformability of "force." Caneva examines Helmholtz's continued engagement with the subject, his role in the acceptance of the conservation of energy as the central principle of physics, and the eventual incorporation of the principle in textbooks as established science.

The conservation of energy, the second law of thermodynamics, the theory of relativity, quantum mechanicstogether, these concepts form the foundation upon which modern physics was built. But the influence of these four landmark ideas has extended far beyond hard science. There is no aspect of twentieth-century cultureincluding the arts, social sciences, philosophy, and politicsthat has not been profoundly influenced by them. In Great Ideas in Physics, Alan Lightman clearly explains the physics behind each of the four great ideas and deftly untangles for lay readers such knotty concepts as entropy, the relativity of time, and the Heisenberg uncertainty principle. Throughout the book he uses excerpts from the writings of scientific luminaries such as Newton, Kelvin, Einstein, and de Broglie to help place each in its proper historical perspective. And with the help of expertly annotated passages from the works of dozens of writers, philosophers, artists, and social theorists, Lightman explores the two-way influences of these landmark scientific concepts on our entire human culture and the world of ideas.

Although produced in controversy, this book is not a controversial work. The calming effects of the years that have passed since the tumultuous days in Lubeck are enough to guarantee that these pages will accurately trace the coming and going of opinions, the battle for the truth and the recognition of error. In only a few passages, especially in Part Six, will one be able to tell from the tone of the book that it comes out of this struggle. For these I ask the indulgence of my reader, since they contain explanations the extent of which probably does not correspond either to the difficulty of the questions treated or to their influence. But in such passages the extent of treatment could not - as was otherwise the case - be made to depend solely on a judgment as to the value and significance of the investigations presented. There considerations of defense, more than concern for symmetry, had to determine the structure.

Energy is at the heart of physics and of huge importance to society and yet no book exists specifically to explain it, and in simple terms. In tracking the history of energy, this book is filled with the thrill of the chase, the mystery of smoke and mirrors, and presents a fascinating human-interest story. Moreover, following the history provides a crucial aid to understanding: this book explains the intellectual revolutions required to comprehend energy, revolutions as profound as those stemming from Relativity and Quantum Theory. Texts by Descartes, Leibniz, Bernoulli, d'Alembert, Lagrange, Hamilton, Boltzmann, Clausius, Carnot and others are made accessible, and the engines of Watt and Joule are explained. Many fascinating questions are covered, including: - Why just kinetic and potential energies - is one more fundamental than the other? - What are heat, temperature and action? - What is the Hamiltonian? - What have engines to do with physics? - Why did the steam-engine evolve only in England? - Why S=klogW works and why temperature is IT. Using only a minimum of mathematics, this book explains the emergence of the modern concept of energy, in all its forms: Hamilton's mechanics and how it shaped twentieth-century physics, and the meaning of kinetic energy, potential energy, temperature, action, and entropy. It is as much an explanation of fundamental physics as a history of the fascinating discoveries that lie behind our knowledge today.

This book offers an easy to read, all-embracing history of thermodynamics. It describes the long development of thermodynamics, from the misunderstood and misinterpreted to the conceptually simple and extremely useful theory that we know today. Coverage identifies not only the famous physicists who developed the field, but also engineers and scientists from other disciplines who helped in the development and spread of thermodynamics as well.

The development of science, according to respected scholars Peter J. Bowler and Iwan Rhys Morus, expands our knowledge and control of the world in ways that affect-but are also affected by-society and culture. In Making Modern Science, a text designed for introductory college courses in the history of science and as a single-volume introduction for the general reader, Bowler and Morus explore both the history of science itself and its influence on modern thought. Opening with an introduction that explains developments in the history of science over the last three decades and the controversies these initiatives have engendered, the book then proceeds in two parts. The first section considers key episodes in the development of modern science, including the Scientific Revolution and individual accomplishments in geology, physics, and biology. The second section is an analysis of the most important themes stemming from the social relations of science-the discoveries that force society to rethink its religious, moral, or philosophical values. Making Modern Science thus chronicles all major developments in scientific thinking, from the revolutionary ideas of the seventeenth century to the contemporary issues of evolutionism, genetics, nuclear physics, and modern cosmology. Written by seasoned historians, this book will encourage students to see the history of science not as a series of names and dates but as an interconnected and complex web of relationships between science and modern society. The first survey of its kind, Making Modern Science is a much-needed and accessible introduction to the history of science, engagingly written for undergraduates and curious readers alike.
