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.
Physicists firmly believe that the differential equations of nature should be hyperbolic so as to exclude action at a distance; yet the equations of irreversible thermodynamics - those of Navier-Stokes and Fourier - are parabolic. This incompatibility between the expectation of physicists and the classical laws of thermodynamics has prompted the formulation of extended thermodynamics. After describing the motifs and early evolution of this new branch of irreversible thermodynamics, the authors apply the theory to mon-atomic gases, mixtures of gases, relativistic gases, and "gases" of phonons and photons. The discussion brings into perspective the various phenomena called second sound, such as heat propagation, propagation of shear stress and concentration, and the second sound in liquid helium. The formal mathematical structure of extended thermodynamics is exposed and the theory is shown to be fully compatible with the kinetic theory of gases. The study closes with the testing of extended thermodynamics through the exploitation of its predictions for measurements of light scattering and sound propagation.
Introductory textbook introducing the concept of competition of entropy and energy with various examples. Thermodynamics textbook explaining the roles of entropy and energy as prime movers of nature.
Experiments with rubber balloons and rubber sheets have led to surprising observations, some of them hitherto unknown or not previously described in the literature. In balloons, these phenomena are due to the non-monotonic pressure-radius characteristic which makes balloons a subject of interest to physicists engaged in stability studies. Here is a situation in which symmetry breaking and hysteresis may be studied analytically, because the stress-stretch relations of rubber - and its non-convex free energy - can be determined explicitly from the kinetic theory of rubber and from non-linear elasticity. Since rubber elasticity and the elasticity of gases are both entropy-induced, a rubber balloon represents a compromise between the entropic tendency of a gas to expand and the entropic tendency of rubber to contract. Thus rubber and rubber balloons furnish instructive paradigms of thermodynamics. This monograph treats the subject at a level appropriate for post-graduate studies.
The concept of entropy arose in the physical sciences during the nineteenth century, particularly in thermodynamics and statistical physics, as a measure of the equilibria and evolution of thermodynamic systems. Two main views developed: the macroscopic view formulated originally by Carnot, Clausius, Gibbs, Planck, and Caratheodory and the microscopic approach associated with Boltzmann and Maxwell. Since then both approaches have made possible deep insights into the nature and behavior of thermodynamic and other microscopically unpredictable processes. However, the mathematical tools used have later developed independently of their original physical background and have led to a plethora of m...
Thermodynamics is the much abused slave of many masters • physicists who love the totally impractical Carnot process, • mechanical engineers who design power stations and refrigerators, • chemists who are successfully synthesizing ammonia and are puzzled by photosynthesis, • meteorologists who calculate cloud bases and predict föhn, boraccia and scirocco, • physico-chemists who vulcanize rubber and build fuel cells, • chemical engineers who rectify natural gas and distil f- mented potato juice, • metallurgists who improve steels and harden surfaces, • - trition counselors who recommend a proper intake of calories, • mechanics who adjust heat exchangers, • architects who ...
Human chemistry is the study of bond-forming and bond-breaking reactions between people and the structures they form. People often speak of having either good or bad chemistry together: whereby, according to consensus, the phenomenon of love is a chemical reaction. The new science of human chemistry is the study of these reactions. Historically, human chemistry was founded with the 1809 publication of the classic novella Elective Affinities, by German polymath Johann von Goethe, a chemical treatise on the origin of love. Goethe based his human chemistry on Swedish chemist Torbern Bergman's 1775 chemistry textbook A Dissertation on Elective Attractions, which itself was founded on Isaac Newton's 1687 supposition that the cause of chemical phenomena may 'all depend upon certain forces by which the particles of bodies, by some causes hitherto unknown, are either mutually impelled towards each other, and cohere in regular figures, or are repelled and recede from one another'; which thus defines life.

From 1938 until 1943 - before the German occupation and accompanying Holocaust - Fascist Italy drafted and enforced a comprehensive set of anti-Semitic laws. Notwithstanding later rationalizations, the laws were administered with a high degree of severity and resulted in serious damage to the Italian Jewish community. Written from the perspective of an American legal scholar, this book constitutes the first truly comprehensive survey of the Race Laws in the English language. Based on an exhaustive review of Italian legal, administrative and judicial sources, together with archives of the Italian Jewish community, Professor Michael A. Livingston demonstrates the zeal but also the occasional ambivalence and contradictions with which the Race Laws were applied by the Italian legal order and ordinary citizens. Although frequently depressing, the history of the Race Laws contains numerous examples of personal courage and idealism, providing a useful and timely study of what happens when otherwise decent people are confronted with an evil and unjust legal order.
Richard Müller, a leading figure of the German Revolution in 1918, is unknown today. As the operator and unionist who represented Berlin’s metalworkers, he was main organiser of the ‘Revolutionary Stewards’, a clandestine network that organised a series of mass strikes between 1916 and 1918. With strong support in the factories, the Revolutionary Stewards were the driving force of the Revolution. By telling Müller's story, this study gives a very different account of the revolutionary birth of the Weimar Republic. Using new archival sources and abandoning the traditional focus on the history of political parties, Ralf Hoffrogge zooms in on working class politics on the shop floor and its contribution to social change. First published in German by Karl Dietz Verlag as Richard Müller - Der Mann hinter der November Revolution, Berlin, 2008, this english edition was completerly revised for the english speaking audience and contains new sources and recent literature.
