First observed by Heinrich Hertz in 1887, the phenomenon is also known as the Hertz effect, although the latter term has fallen out of general use.

( The term “ race hatred ” had also been used by sociologist Frederick Hertz in the late 1920s.

A later edition is that of M. Hertz ( Berlin, 1883-85 ; there is also a smaller edition by the same author, Berlin, 1886 ), revised by C. Hosius, 1903, with bibliography.

It is also home to the Heinrich Hertz Submillimeter Telescope, or SMT.

He also played Mr. Hertz in the action film Shoot ' Em Up and Santa Claus in the comedy Fred Claus.

Hertz also led the orchestra on a number of radio broadcasts.

They soon switched to electrical recordings with Victor, also conducted by Hertz, which continued until 1930.

Angular frequency omega | ω ( in radians per second ), is larger than frequency nu ( letter ) | ν ( in cycles per second, also called Hertz | Hz ), by a factor of 2π.

From the perspective of dimensional analysis, the unit Hertz ( Hz ) is also correct, but in practice it is only used for ordinary frequency f, and almost never for ω.

Only Hillel's brother Shebna is mentioned ; he was a merchant, whereas Hillel devoted himself to studying the Torah whilst also working as a woodcutter ( Hertz 1936 ).

However a friend of his father, who was a Nobel Prize laureate, arranged for Hertz to be freed and also found him a job in Lund, Sweden so that he could leave the States while still not having to return to Germany.

His son, professor Hans Hertz, is currently employed at Royal Institute of Technology, Stockholm Sweden involved in biomedical physics, and also appointed to the Swedish Royal Academy of Science.

They also did a series of ads for Hertz car rentals in the 1980s.

Naphtali Herz Imber (,, also known as Naphtali Tzvi Imber, Naphtali Zvi Imber, Naphtali Hertz Imber or Naphtali Hirsch Imber, 1856 – 8 October 1909 ) was a Jewish poet and Zionist who wrote the lyrics of Hatikvah, the national anthem of the State of Israel.

The Yellow Cab Manufacturing Company was established in 1920 by John D. Hertz and was associated with the Yellow Cab Company which Hertz also owned.

This structure gives the instrument its exceptional sonority and tonal quality among all percussion instruments and also the rich harmonics which range from its tuned pitch of a few hundred Hertz to a few KiloHertz.

Until recently the most common Hebrew-English Humash ( holy book ) used has been the Pentateuch and Haftarahs, edited by Rabbi Joseph H. Hertz ; in recent years this has been supplanted by The Chumash: The Stone Edition, also known as the Artscroll Chumash.

There are later accounts of him by M. Hertz ( 1860 ), G. Schwertzell ( 1874 ) and C. Krause ( 1879 ); see also D. F. Strauss, Ulrich von Hutten ( Eng.

On the other hand, George Gabriel Stokes stated in 1845 that the aether was fully dragged by matter ( later this view was also shared by Hertz ).

Asked about the ramifications of his discoveries, Hertz replied, " Nothing, I guess.

During World War I, Hertz served in the military from 1914.

Since Hertz was an officer during World War I, he was temporarily protected from National Socialist policies and the Law for the Restoration of the Professional Civil Service, but eventually the policies and laws became more stringent, and at the end of 1934, he was forced to resign his position at BTH, as he was classified as a “ second degree part-Jew ” ( his paternal grandfather had been Jewish ).

Robert Hertz ( 1881, Saint-Cloud, Hauts-de-Seine-1915 ) was a French sociologist who was killed in World War I.

During World War I, his family fled eastwards from the German invasion and settled in Omsk, Siberia, where his father, Hertz Sutzkever, died.

He was involved in the design of London General's B-Type bus, under Frank Searle and then George Green ; during World War I, he and Green worked on the Tank along with other gifted engineers such as Walter Wilson, after the war he had moved to the United States and under Green had been chief designer for John Hertz ' Yellow Coach Company, one of the leading bus-builders in the States, Rackham, under Green's direction had evolved a range of fast, relatively light chassis with powerful engines and a trademark of frames gracefully swept with elegantly varying side-member depth, the Y and Z models also had off-set under-slung worm rear-axles and six-cylinder overhead-camshaft ( OHC ) petrol engines, OHC was not generally known in UK buses at the time and six-cylinder engines likewise.

Hertz had been surprised to find that it was not necessary to discharge large batteries through one of these spirals in order to obtain sparks in the other ; that small Leyden jars amply sufficed for this purpose, and that even the discharge of a small induction coil would do, provided it had to spring across a spark gap.

The peasants bring her body to Dr Hertz to see if he can do anything.

John Hertz initially did not think much of Count Fleet and contemplated selling him until jockey Johnny Longden convinced him to keep the colt.

In 1888, Heinrich Hertz demonstrated the existence of electromagnetic waves, the underlying basis of most wireless technology.

German scientists Eilhard Wiedemann, Heinrich Hertz and Goldstein believed they were " aether waves ", some new form of electromagnetic radiation, and were separate from what carried the electric current through the tube.

Radio waves were not detected first from a natural source, but were rather produced deliberately an artificially by the German scientist Heinrich Hertz in 1887, using electrical circuits calculated to produce oscillations in the radio frequency range, following recipies suggested by the equations of James Clerk Maxwell.

In his classic UHF experiments of 1888, Heinrich Hertz transmitted ( via a spark-gap transmitter ) and detected radio waves using electrical equipment.

As early as 1886, German physicist Heinrich Hertz showed that radio waves could be reflected from solid objects.

Radio waves were not detected first from a natural source, but were rather produced deliberately an artificially by the German scientist Heinrich Hertz in 1887, using electrical circuits calculated to produce oscillations in the radio frequency range, following recipes suggested by the equations of James Clerk Maxwell.

Hertz changed the frequency of his radiated waves by altering the inductance or capacity of his radiating conductor or antenna, and reflected and focused the electromagnetic waves, thus demonstrating the correctness of Maxwell's electromagnetic theory of light.

Heinrich Hertz ( 1888 ) demonstrated the existence of electromagnetic radiation ( radio waves ) in a series of experiments in Germany during the 1880s.

Hertz showed methods of producing, detecting, and measuring these waves.

Hertz used the damped oscillating currents in a dipole antenna, triggered by a high-voltage electrical capacitive spark discharge, as his source of radio waves.

When he added cylindrical reflectors behind his dipole antennas, Hertz could detect radio waves about 20 metres from the transmitter in his laboratory.

Hertz ’ s setup for a source and detector of radio waves ( then called Hertzian waves in his honor ) was the first intentional and unequivocal transmission and reception of radio waves through free space.

* 1888: Heinrich Hertz of Hamburg, a city-state of the German Empire, successfully transmits and receives radio waves.

Attempting to experimentally prove James Clerk Maxwell ' " A dynamical theory of the electromagnetic field " ( 1864 ), Hertz " generated electric waves using an electric circuit ".

Hertz succeeded in proving the existence of electromagnetic waves.

* Heinrich Hertz discovers the photoelectric effect on the production and reception of electromagnetic ( EM ) waves ( radio ).

* November 11 – Heinrich Hertz verifies at the University of Karlsruhe the existence of the electromagnetic waves.

The first primitive radio transmitters ( called Hertzian oscillators ) were built by German physicist Heinrich Hertz in 1887 during his pioneering investigations of radio waves.

In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory.
