Untersuchungen Ueber die Ausbreitung der elektrischen Kraft [ ?ber ]
Leipzig: Johann Ambrosius Barth, 1892. Half-Leather. Very Good. VI, [2], 295, [1] pages. Half leather over marbled boards. Minor wear and scuffing to the leather extremities, front joint just starting at top. Bright and clean internally. 'THE THEORY OF WIRELESS TELEGRAPHY'. Hertz produced experimental proof of Faraday and Maxwell's hypothesis that 'electrical waves can be projected through space...' starting in 1887. 'By inducing the waves to produce an electric spark at a distance, with no apparentt connexion 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...J. J. Thomson described the results as 'one of the most marvellous triumphs of experimental skill.'' This volume collects and reprints papers on electrical waves first published between 1887-1890 in Annalen der Physik und Chemie. Includes explanatory notes and Hertz's 31 page introduction. 'This discovery and its demonstration led directly to radio communications, television and radar.' See Norman 1061, PMM 377, Ekelof 1455, Dibner Heralds of Science 71 (refering to one of the articles in Annalen), Sparrow Milestones of Science p.47. Half-Leather.
