Heinrich Rudolf Hertz Celebrated In The Google Doodle

German physicist whose experiments led to the wireless telegraph and radio, has his one hundred fifty-fifth birthday marked

Google's recent animated doodle celebrates the birthday 155 of Heinrich Hertz, German physicist whose experiments with electromagnetic waves led to the development of wireless telegraphy and radio.

Born in Hamburg, where he demonstrated a great ability to capture the dynamics of physics, even in infancy, later enrolled to study the issue in Berlin after a year at the University of Munich.

In Berlin, progress in research on electromagnetic phenomena was so rapid that in February 1880 received his doctorate - on electromagnetic induction in rotating spheres - at the age of 22 years.

After becoming a professor at the Technische Hochschule in Karlsruhe in 1885, Hertz turned his attention to open electrical circuits and electromagnetic induction, showed his students with a capacitor discharge through an open circuit.

During this way realized an unexpected phenomenon, the appearance of "side-sparks' in another loop by. In 1888, he was able to show that the electromagnetic emissions associated with these sparks behave like waves.

The finding, which actually clarified and expanded the electromagnetic theory of light that had been raised by the British physicist James Clerk Maxwell in 1884, was hailed as a confirmation that electromagnetic waves could be transmitted and received.

Hertz name later became the term used for radio and electrical frequencies, as in hertz (Hz), kilohertz (kHz) and megahertz (MHz).

He died in Bonn in 1894 after contracting Wegener's granulomatosis, a rare disease in which blood vessels become inflamed, and was buried in Ohlsdorf, Hamburg.
