So a fast rotor, a middle rotor, and a slow rotor.

Rotor

Rotor

Don't make mistakes again, whether you drop the ring or you step on your own dress and slip.

Civil Rotor

Why, it's no work at all. You merely slip this ring over the limb like this, and haul it off.

When this rotor does a full turn, it'll kick the next rotor one place.

Ring... Ring...

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

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

Eventually, the middle rotor does a full turn, and it will kick the left hand rotor one place.

Slip

We lost the tail rotor! It's gone!

Packing Slip

Don't slip!

MERCUTlO The slip, sir, the slip can you not conceive?

And then, the right hand rotor keeps going.

We have 26 starting positions for each rotor.

It will ring. It will ring.

No, don't ring. Please don't ring.

The ring. Give him Pompey's ring.

Slip Slidin' Away.

Oops, a slip!

Your deposit slip?

This is the rough idea behind rotor encryption machines.

The Enigma is a kind of complicated rotor machine.

And if you manipulate the speed of this rotor, you are actually able to crack the rotor and eventually even have the centrifuge explode.

And the other way around, if you increase the speed of rotor three and decrease the speed of rotor one, then the robot pitches forward.

And the other way around, if you increase the speed of rotor three and decrease the speed of rotor one, then the robot pitches forward.

This destroyed the uniform distribution of the initial rotor position, and after repeated observations, it allowed the allies to reverse engineer the rotor wirings completely.

Ah, I let slip.

No, I didn't slip.

I'll let it slip.

Your slip shows, dear.

I'll just slip away.

Hand me my slip.

Please, I might slip.

Slip through our fingers?

Better slip into this.
