Slow the car down.

It's actually hitting a tooth.

Gearhead

A gearhead

Before this happened, I was a cog in the machine.

Slowing down.

Slowing down?

That gives us a limit on speed as well.

Launch coming up off the stern, sir. Half speed.

Decelerate.

Decelerate.

Number of gears

What's in the gears?

I don't think he brushes his teeth enough.

They're slowing down.

You can do bigger things.

It's because the pulse of light is not coming back through the same notch.

So, we went down actually.

And then, based on the distance between the two stations and the speed of his wheel and the number of notches in the wheel, he calculates the speed of light to within two percent of its actual value.

They're in the gears.

We should take our foot off the pedal right now, and generally we do.

Slow us down.

They've dropped to impulse.

The Spider's slowing!

The choice in this case is pretty simple.

That's because we're, kind of, where the velocity of train A is being eaten away by the velocity of B.

It's easy. All you got to do is tap on the brakes a little bit.

Come on. Decelerate!

the light's red.

Running a little hot. Want to open up a speed brake?

The cog wheels are in gear.

Motorway

It's a ninespeed bike.

Which one of these here cars is the fastest?

All hands squared away to decelerate.

Don't slow down.

Central has asked me to slow down the harvesters... to ensure you have time to recuperate and get your strength back.

A small gear is missing here.

What would happen if we captured it?

It's the way all can be part of that wheel.

I probably can't do both.

All right. We're down to 0.3896 of light speed.

I'm like, Okay, all right, this guy is slowing down,

The train gathered speed.

In this situation, we do it in 15 seconds.
