The return spring on the throttle cable, or...

But you can imagine, if I have just a wall, and then I have a spring attached to some mass right there, and let's say that this is a natural state of the spring, so that the spring would want to be here, so it's been stretched a distance y from its kind of natural where it wants to go.

And I'll say this is a positive rightward direction, so it's that force, and then you have a minus force from the spring.

Watch that hand on the spring.

Or I heard the peep of the young when I could not see the parent bird.

(Laughter)

So we thought, OK, this must be a spring the saddle could very well be a spring.

And let's say I have some external force right here.

It's not the spring. It's the linkage from the pedal to the carb. See?

The spring slams shut in 38 thousands of a second.

There's a cuff and a spring. They both have teeth.

There needs to be some kind of spring loaded mechanism in order to generate the amount of force that we observe, and the speed that we observe, and the output of the system.

If you look on this, imagine a piano keyboard.

like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

These molecules, as you saw in the beginning, the building blocks had springs connecting them to each other.

It seems she hurt her leg.

Signs of the zodiac.

They all work like this kangaroo, they bounce.

We couldn't believe that it could do this.

So if you had no outside force, if this was zero you'd have a homogeneous differential equation.

You push down on the spring, disengage the teeth like that.

A sofa sprouting springs... a 24 hour water supply from the leaking roof

Commonly I rested an hour or two in the shade at noon, after planting, and ate my

I knew it would be like that, so I made these.

Would you like me to put them on for you?

Sit back.

Sit down. No.

Get down! Now! Get in here!

I sit on the toilet.

The animals, when you look at them running, appear to be self stabilizing like this, using basically springy legs.

Aries is a fire sign, Martin.

Sit down, everybody, sit down.

You don't think I was right?

And then instead of giving them actual gold,

Why don't you all sit down? Donald, sit down.

Interestingly, what I did with these rollers is, basically, I took them off of these mouses and then put them in one line.

I translate natural mechanics into wooden parts that are operated by strings and springs.
