“What’s the frequency, Heinrich?” haiku

Catch a birthday wave
Electromagnetically
Google salutes Hertz

Hertz was first to prove
Electromagnetic waves
Really existed

Showed radio waves,
Light had same velocity
Could be transmitted

Thought his findings were
“Of no use whatsoever”
Boy, he got that wrong

Led to radio
And wireless telegraph,
Rent-a-cars (kidding)

They named the unit
Of radio frequency
The hertz after him

And that’s Heinrich Hertz
Not Heinrich’s uncle Hertz Hertz
Then we’d have hertz squared
