First edition of Cavendish's groundbreaking electrical research.

Henry Cavendish (1731-1810), the grandson of the second duke of Devonshire, wrote papers on electrical topics for the Royal Society, but the majority of his electrical experiments did not become known until they were collected and published by James Clerk Maxwell a century later, in 1879, long after other scientists had been credited with the same results. Among Cavendish's discoveries were the concept of electric potential, which he called the 'degree of electrification'; an early unit of capacitance, that of a sphere one inch in diameter; the formula for the capacitance of a plate capacitor; the concept of the dielectric constant of a material; the relationship between electric potential and current, now called Ohm's Law; laws for the division of current in parallel circuits, now attributed to Charles Wheatstone; and the inverse square law of variation of electric force with distance, now called Coulomb's Law.

Henry Cavendish (1731-1810) was an English scientist whose published work was mostly concerned with electricity. He was elected a Fellow of the Royal Society in 1760. Cavendish was a prolific scientific investigator, performing experiments on not only electricity but also magnetism, thermometry, gases, heat potential and the chemical composition of water. Although he published some of his research, including his discovery of hydrogen, the majority of his work remained unpublished until 1879, when James Clerk Maxwell published a collection of Cavendish's electrical experiments. These papers showed that Cavendish had discovered many important electrical concepts which had since been credited to other researchers, including the concept of electric potential. First published in 1921, these volumes are a collection of Cavendish's results from his many experiments. Volume 1 is a revised edition of James Clerk Maxwell's 1879 volume Electrical Researches of Henry Cavendish, also reissued in this series.

Profiles the eminent 18th century natural philosopher Henry Cavendish, best known for his work in chemistry and physics and one of the most baffling personalities in the history of science. In these chapters we are introduced to the psychology of science and of scientists and we learn about Cavendish’s life and times. His personality is examined from two perspectives: one is that he had a less severe form of autism, as has been claimed; the other is that he was eccentric and a psychological disorder was absent. Henry Cavendish lived a life of science, possibly more completely than any other figure in the history of science: a wealthy aristocrat, he became a dedicated scientist. This study brings new information and a new perspective to our understanding of the man. The scientific and non-scientific sides of his life are brought closer together, as the author traces topics including his appearance, speech, wealth, religion and death as well as Cavendish’s life of natural philosophy where objectivity and accuracy, writing and recognition all played a part. The author traces aspects of Cavendish’s personality, views and interpretations of him, and explores notions of eccentricity and autism before detailing relevant aspects of the travels made by our subject. The author considers the question “How do we talk about Cavendish?” and provides a useful summary of Cavendish’s travels. This book will appeal to a wide audience, from those interested in 18th century history or history of science, to those interested in incidences of autism in prominent figures from history. This volume contains ample relevant illustrations, several interesting appendices and it includes a useful index and bibliography.
