[6][7][8], Hertz's wife, Elisabeth Hertz (née Doll; 1864–1941), did not remarry. In 1886–1889, Hertz published two articles on what was to become known as the field of contact mechanics, which proved to be an important basis for later theories in the field. the work done when the point of application of a force of one newton is displaced a distance of one metre in the direction of the force: 3: watt: W: the power that produces energy at the rate of one joule per second: 4: hertz: Hz: the frequency of a periodic phenomenon of which the periodic time is one second: 5: coulomb: C Hertz measured Maxwell's waves and demonstrated that the velocity of these waves was equal to the velocity of light.

After Hertz received his professorship at Karlsruhe he was experimenting with a pair of Riess spirals in the autumn of 1886 when he noticed that discharging a Leyden jar into one of these coils produced a spark in the other coil. He stated that,[18][19][20], Asked about the applications of his discoveries, Hertz replied,[18][21], Hertz's proof of the existence of airborne electromagnetic waves led to an explosion of experimentation with this new form of electromagnetic radiation, which was called "Hertzian waves" until around 1910 when the term "radio waves" became current. Hertz, H.R. Vehicle diversity: Hertz Tahiti offers sedans and breaks, but also SUV and 4x4 cars to survey the roads of Polynesia and many other types of vehicles for your travels through Tahiti. Within 10 years researchers such as Oliver Lodge, Ferdinand Braun, and Guglielmo Marconi employed radio waves in the first wireless telegraphy radio communication systems, leading to radio broadcasting, and later television. Hertz's grandnephew Hermann Gerhard Hertz, professor at the University of Karlsruhe, was a pioneer of NMR-spectroscopy and in 1995 published Hertz's laboratory notes.[32].

Helmholtz had also proposed the "Berlin Prize" problem that year at the Prussian Academy of Sciences for anyone who could experimentally prove an electromagnetic effect in the polarization and depolarization of insulators, something predicted by Maxwell's theory. He did not further pursue investigation of this effect, nor did he make any attempt at explaining how the observed phenomenon was brought about. Consultant Conseil en Stratégie Immobilière H/F.
