With the signature of Lord Kelvin: This copy was presented as a gift to a student at the University of Glascow by Lord Kelvin, Professor of Natural Philosophy at the university and one of the most accomplished scientists of the nineteenth century. (Kelvin was also the author of the preface to the present volume.) |
| "For electricity and magnetism Faraday's anticipations and Clerk-Maxwell's splendidly developed theory have been established on the sure basis of experiment by Hertz's work, of which his own most interesting account is now presented to the English reader by is translator, Professor D.E. Jones." -Lord Kelvin, from the preface |

Hertz, Heinrich. Electric Waves: Being Researches on the Propagation of Electric Action with Finite Velocity Through Space. Translated by David Evan Jones. Preface by William Thompson, Lord Kelvin. London and New York: Macmillan and Co., 1893. Octavo, full contemporary calf presentation binding with gilt stamp arms from the University of Glascow on front board, elaborately gilt-decorated spine. "By inducing the waves to produce an electrical spark at a distance, with no apparent connection between the oscillator and the spark gap, and by moving the sparking apparatus so that the length of the spark varied, Hertz proved beyond question the passage of electric waves through space" (PMM 377). First edition in English of Hertz's collected papers on electromagnetic waves; the foundation for wireless communication. Originally published in German in 1892, the collected edition gathers together Hertz's important journal publications from 1887-1892 with the addition of an introduction in which Hertz surveys and analyzes his work of the past five years. PMM (Printing and the Mind of Man), 377 (for the German edition). With the signature of Lord Kelvin: This copy was presented as a gift to a student at the University of Glascow by Lord Kelvin, Professor of Natural Philosophy at the university and one of the most accomplished scientists of the nineteenth century. (Kelvin was also the author of the preface to the present volume.) Light scuffing to binding, otherwise fine. Also see: The first journal printings of Hertz's discoveries in electromagnetic waves. |
