“Nothing changes, or moves, and there’s only one thing”,

Said Mr. Perry Mena Dees.

“That's bananas! “It’s bonkers” The Greek chorus would sing.

It doesn’t add up, don’t you see?

But if we’re adding things up, Dee’s friend Zeno replied,

Then let us consider a case

Where a hero, Achilles, no matter how hard he tried,

Still couldn’t finish a race.

Imagine, lets say, that our hero competed

Against a turtle, who as we all know

Is most likely the one who would be defeated

In a race, since all turtles are slow.

But if the turtle were given just a tiny advantage,

Just a head start of a few dozen yards

Then our hero Achilles never could manage

To win, even if he ran hard.

After all, explained Zeno, to win such a sprint

The hero first must travel halfway

And in the time that he took, the turtle’s footprints

Would have carried her further away.

And so it would go, as the hero raced on,

That every time he gained some new ground

The turtle, his foe, would already be gone

By the time poor Achilles came ‘round.

Whenever the hero arrived at the spot

That the turtle had covered before,

The turtle moved on, she still wasn’t caught,

As Achilles tried to exceed her once more.

On and on it would go, forever it’d seem.

So if you think Dee’s wrong and things move.

Your view is strange too, you see what I mean?

And Dee’s claim’s pretty hard to disprove.

Since Dee and Zeno (the Greek Chorus too),

A lot of people have tried to explain,

Why Zeno and Dee and their silly view

Is really a trick for your brain.

The solution, it seems, is an idea that’s strange,

Called infinity, or infinite sums

If he runs fast enough, if his speed stays the same

Our hero can win the race he has run

The reason is tricky, but it surely adds up

Like one half plus, one quarter, one eighth…

If you sum all those numbers, soon enough

Achilles has one in good faith.

But we’d never know why the world is this way

If Zeno and Dee hadn’t asked a good question

And that's why we should thank them, even today

For this strange and exciting digression.
