Today’s google doodle features a never-ending loop of colorful waves.

Unlike other doodles, this one does not form the letters of the search engine’s famous logo.

The doodle is in honor of the 155th birthday of Heinrich Rudolf Hertz, German physicist who clarified and expanded the electromagnetic theory of light that had been put forth by Maxwell.

Hertz who was born on February 22, 1857 in in Hamburg, Germany was the first to satisfactorily demonstrate the existence of electromagnetic waves by building an apparatus to produce and detect radio waves.

Hertz’s experiments would soon trigger the invention of the wireless telegraph, radio, and later television. In recognition of his work, the unit of frequency – one cycle per second – is named the “hertz”.

He died of Wegener’s granulomatosis (incurable form of vasculitis (inflammation of blood vessels) that affects the nose, lungs, kidneys and other organs) at the age of 36 in Bonn, Germany in 1894.
