Thumbs allow some species to use tools.

Dinosaurs The bird like dinosaur Troodon had a partially opposable finger.

The wheel is turning.

The thumbs are opposable and the index finger is short.

Moore's law made computing cheap so cheap we can weigh the life of an individual insect and decide thumbs up or thumbs down.

The testicles emerge they look like thumbs, coming right at you and he says, Bite 'em.

And there's a rotor there that this motor is spinning.

So we have these stars going around in circles like this.

The top is turning clockwise.

So in this picture you see that rotor four is spinning faster and rotor two is spinning slower.

And for all of you, you'll see it probably spinning this direction.

And turning around you is shhhhhhhhhhhhh, like that.

It's got tentacles dangling, swirling around like that.

Other animals with opposable digits Many non human animals also have some kind of opposable thumb or toe.

We're going to move even further down, and go to one single electron spin.

He that is giddy thinks the world turns round.

The stator is the stationary part of the motor s electromagnetic circuit.

Now the things that relate to it are swirling around.

And I was rotating it in 3D and saying, I understand now.

Everybody's head was spinning, so we thought, why not keep that momentum going...?

Wittgenstein replied, Well, what would it have looked like if it had looked as though the Earth was rotating?

This is a a highly condensed clump of neutral matter, spinning in the distant universe.

This yoyo right here cost 112 dollars, but it sleeps for 12 minutes.

And here you can see it's rotating about the vertical axis only, creating circles.

She wakes to find the house spinning in the air, held aloft by the twister.

A squall is a doubling of the wind speed above a certain threshold, which lasts for a minute or more.

My neighbors are my friends.

They're my students, my friends.

In many instances where it did not work the shroud lines became entangled with the spinning aircraft.

It's up there with opposable thumbs and standing upright and language as one of the things that got our species out of the trees and into the shopping mall.

Imagine if a team of physicists could stand inside of an atom and watch and hear electrons spin.

My archive 175 films, my 16 millimeter negative, all my books, my dad's books, my photographs.

And then I saw my own parents, my first teachers.

So, think about it as a paper thin, huge area of many hundreds of thousands of miles, which is rotating.

A downside of this method is that an object rotating at an integer multiple of the strobing frequency will also appear stationary.

Congratulations!

My condolences!

They're mine.

I'm sorry for your loss.

High speed rotating wheels operating at speeds of about 20,000 rpm are able to process up to 60,000 pounds (27 tonnes) of solution per hour (ref 3).

My sweet angels, come back.

These are my pencils.

My eyes feel itchy.

My eyes hurt.
