Google's "Doodle" Remembering 155th Heinrich Rudolf Hertz Birthday

You are certainly familiar with the unit of frequency "Hertz". The unit was taken from the name of an electromagnetic physicist, Heinrich Rudolf Hertz. Today, Wednesday (02/22/2012), Google appreciate the services of Hertz is represented through decorative Google Doodle design on the front page of the search engine site.

Heinrich Rudolf Hertz 155th Birthday

Hertz was born in Hamburg, Germany, on February 22, 1857. He is a physicist who tested the hypothesis of electromagnetic light that proposed by James Clerk Maxwell.

In 1885, Hertz became a professor at the University of Karlsruhe, Germany. Later, he became the first to demonstrate the existence of electromagnetic waves by building tools to produce and detect radio waves.

In more advanced experiments, Hertz measured the speed of electromagnetic radiation and found the same thing with the speed of light. He also showed that the radio waves reflection characteristic is equal to the light. It answers the question that light is a form of radiation, as well as prove Maxwell hypothesis.

Not only that, light characteristic that occurs in electromagnetic waves also succeed proven by Hertz, such as refraction, reflection, interference, polarization, and diffraction.

What Hertz has been done triggered the discovery of the wireless telegraph, radio, and television.

In addition to preserved as the unit of frequency Hertz, his name is also used to a product market area radioelektronik in Nizhny, Novgorod, Russia. There is also a radio telecommunication tower Heinrich-Hertz-Turm in Hamburg, Germany.

Hertz died on January 1, 1894 at the relatively young age, 36 years old. He died of Wegener's granulomatosis, a disease due to inflammation of blood vessels that invade the nose, ears, throat and other organs
