Couverture souple. Condition: Très bon. Edition originale. 1906 ; in-8 (215 x 138 mm), pp. 468-474, 4 fig. dans le texte, couverture verte imprimée, petite étiquette de classement sur le plat supérieur (avec l'inscription B-230) sans autre marque ou ex-libris, très bon état. Edition originale. Tirage à part très rare. Camille Tissot (1868-1917), officier de marine français, professeur à l'Ecole Navale, fut un précurseur de la télégraphie sans fil. Il expose ici les résultats de ses expériences, similaires à celles menées indépendamment par Duddell et Taylor. Il montre que l'intensité reçue est inversement proportionnelle à la distance (loi de Duddell et Taylor, Duddell-Taylor-Tissot law or formula). Cf. J.E. Murray, A Handbook of Wireless Telegraphy, p.124 : "Tissot's Bolometer Bridge. ? Lieutenant C. Tissot, of the French Navy, has devised a kind of bolometer for use in the measurement of the received current in wireless telegraphy, and has made many useful measurements by its means." ; C.P. Yeang, Characterizing radio channels: the science and technology of propagation and interference, 1900-1935, p. 68 : "William Duddell and J.E. Taylor in Britain and Camille Tissot in France had performed similar experiments in 1904 and 1906 respectively. Working within a 50-mile range, they had discovered that antenna current was inversely proportional to distance.".

Good overall; some bumping/rubbing/fraying to extremities; scuffs to cloth; spine is weak, with front hinge starting and binding exposed between gatherings in a few places; spine cocked; foxing to endpapers; else Fine. Pages clean and bright except as noted. A photo-reproduction of Hertz's portrait is pasted to the flyleaf. No dust jacket. Presumed First Edition in English; there is no copyright page, but the date on the title page is 1893, and the "Translator's Note" is dated December 1893. Bound in green buckram with gilt titling; 6x9 inches; xv, 278, [1] pp. Dr. Harold Sidebotham (1864-1945) of Santa Barbara has signed the second free page, and his name is printed in pencil on the dedication page, next to a stamp "Disposed of by S.B. Museum of Natural History [SBMNH]". The museum's embossed stamp is at the bottom of the title page, but no other ownership or library marks are present. Dr. Sidebotham was one of the founders of the Quisisana Sanitarium in Santa Barbara, later to become St. Francis Hospital. He served as Director of SBMNH briefly in 1932. The significance of his name printed on the dedication page may be that he donated the book to the museum library in 1942, the date next to his name. Book.

'This discovery and its demonstration led directly to radio communication, television and radar' (Dibner, Heralds of Science, 71). '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' Printing and the Mind of Man, 377).

SECOND EDITION IN ENGLISH of Untersuchungen uber die Ausbreitung der elektrischen Kraft. "Hertz was the first to demonstrate experimentally that electromagnetic waves radiate in space at the speed of light, just as Maxwell had predicted in his Treatise on Electricity and Magnetism. Hertz determined that electromagnetic waves were longer than light waves and showed that they were in complete correspondence with the waves of light and heat in the transverse nature of their vibration and their susceptibility to reflection, refraction, and polarization." [Hook & Norman]. "Experimental proof by Hertz of the Faraday-Maxwell hypothesis that electrical waves and be projected through space was begun in 1887, eight years after Maxwell's death. The two main requirements were (a) a method of producing the waves, supposing that they existed, and (b) a method of detecting them once they were produced. Hertz found the first problem easy to solve. He used the oscillatory discharge of a condenser. Detection was much more difficult, because there then existed no means of detecting currents alternating at the high speed of these waves. Hertz in fact used an effect as old as the discovery of electricity itself-the electric spark. By inducing the waves to produce an electric spark at a distance, with no apparent connexion between the oscillator and the spark gap, and by moving the sparking apparatus so that the length of the spark varied, he proved beyond question the passage of electric waves through space."

Hardcover. Condition: Very Good. 1st Edition. FIRST EDITION IN ENGLISH in original cloth of Hertz's collected papers on electromagnetic waves; the foundation for wireless communication. "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" (Printing and the Mind of Man, 377). 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.
