I'm gonna tell you a little secret. If I take

a dolphin and I slow it down... It sounds like

a monkey. If I take a chimpanzee... And I speed

it up... Sounds like a mouse. If I take a mouse,

slow it down... It sounds like a seagull. If

I take a seagull... And slow the seagull down...

Sounds like a gorilla or a whale. If I take

a whale... And we speed the whale up... Sounds

like birds. Here's some cows, sped up. They

sound like puppies. If we slow crickets down...

We're back at birds. Information is transmitted

via waves. We can see that, we can hear that.

The fundamental is the carrier wave. The harmonics

differentiate my voice from a singer. Whales

communicate below our hearing, so we have to

speed it up to hear it. Our hearing is right

here, and above it... Freakin' bats. I love

Halloween. Freakin' bats, and whales, and dolphins

use higher frequencies to see. They bounce the

waves off to get an image. Everything is connected

this way. Grizzly bears even sound like humans.
