Lazare Carnot was the unique example in the history of science of someone who inadvertently owed the scientific recognition he eventually achieved to earlier political prominence. He and his son Sadi produced work that derived from their training as engineers and went largely unnoticed by physicists for a generation or more, even though their respective work introduced concepts that proved fundamental when taken up later by other hands. There was, moreover, a filial as well as substantive relation between the work (...) of father and son. Sadi applied to the functioning of heat engines the analysis that his father had developed in his study of the operation of ordinary machines. Specifically, Sadi's idea of a reversible process originated in the use his father made of geometric motions in the analysis of machines in general. (shrink)

Originally published in 1960, The Edge of Objectivity helped to establish the history of science as a full-fledged academic discipline. In the mid-1950s, a young professor at Princeton named Charles Gillispie began teaching Humanities 304, one of the first undergraduate courses offered anywhere in the world on the history of science. From Galileo's analysis of motion to theories of evolution and relativity, Gillispie introduces key concepts, individuals, and themes. The Edge of Objectivity arose out of this course. It must have (...) been a lively class. The Edge of Objectivity is pointed, opinionated, and selective. Even at six hundred pages, the book is, as the title suggests, an essay. Gillispie is unafraid to rate Mendel higher than Darwin, Maxwell above Faraday. Full of wry turns of phrase, the book effectively captures people and places. And throughout the book, Gillispie pushes an argument. He views science as the progressive development of more objective, detached, mathematical ways of viewing the world, and he orchestrates his characters and ideas around this theme. This edition of Charles Coulston Gillispie's landmark book introduces a new generation of readers to his provocative and enlightening account of the advancement of scientific thought over the course of four centuries. Since the original publication of The Edge of Objectivity, historians of science have focused increasingly on the social context of science rather than its internal dynamics, and they have frequently viewed science more as a threatening instance of power than as an accumulation of knowledge. Nevertheless, Gillispie's book remains a sophisticated, fast-moving, idiosyncratic account of the development of scientific ideas over four hundred years, by one of the founding intellects in the history of science. Featuring a new foreword by Theodore Porter, who places the work in its intellectual context and the development of the field, this edition of The Edge of Objectivity is a monumental work by one of the founding intellects of the history of science.

Denis Guedj’s La Méridienne ; où comment Jean‐Baptiste Delambre et Pierre Méchain, traversant la France révolutionnaire à la rencontre l’un de l’autre, parvinrent à définir un nouvel étalon universel, le mètre, is a novel about the survey of the meridian of Paris on which the metric system was based. The author’s account distorts and falsifies the facts in order to make what he considers a good story. This essay contrasts that approach with writings on history of science by other than (...) historians of science and with two historical novels that are faithful to the historical record. (shrink)
