Check Out Google's Minimalistic Animated Doodle Celebrating Heinrich Hertz

Google is running a very interesting and minimalistic doodle on its homepage across the world, marking the birthday of German physicist Heinrich Rudolf Hertz. You've probably at least heard of his last name, even if you didn't know what it meant.

Hertz's biggest contribution to science was in proving that electromagnetic waves existed, that they traveled at the speed of light and had other wave and light properties such as reflection or refraction proving that light was just a form of electromagnetic wave, as predicted and proved theoretically by James Clerk Maxwell some 20 years earlier.

The SI unit for frequency, which measures the number of times something repeats itself in a second, is named in his honor, which is why your processor's clock speed, FM radio frequencies and so on are all measured in Hertz.
