Mighty strange.

That's an odd-Iooking creature.

What kind of a crazy place is this?

Well, what do you know? Square roots!

Pi is equal to 3.141592653589747

etcetera, etcetera, etcetera.

Huh?

Hello!

(ECHOING) Hello! Hello!

SPIRIT: Hello, Donald.

That's me. Where am I?

SPIRIT: Mathemagic Land.

Mathmagic Land? Never heard of it.

SPIRIT: It's the land of great adventure.

Well, who are you?

SPIRIT: I'm a spirit.
The True Spirit of Adventure.

That's for me. What's next?

SPIRIT: A journey through
the wonderland of mathematics.

Mathematics? That's for eggheads.

SPIRIT: Eggheads?
Now hold on, Donald.

You like music, don't you?

Yeah.

SPIRIT: Well, without eggheads,
there would be no music.

(EX CLAIMS)

SPIRIT: Come on,
let's go to ancient Greece.

To the time of Pythagoras,
the master egghead of them all.

Pythagoras?

SPIRIT: The father of mathematics
and music.

DONALD: Mathematics and music?

SPIRIT: You'll find mathematics
in the darndest places.

Watch.

- SPIRIT: First, we'll need a string.
- Hey!

SPIRIT: Stretch it good and tight,
plunk it.

(TWANGING)

Now, divide in half.

Plunk again.

You see?
It's the same tone, one octave higher.

Now divide the next section,

and the next.

Pythagoras discovered
the octave had a ratio of 2-to- 1.

With simple fractions, he got this.

(MAJOR SCALE PLAYING)

And from this harmony in numbers
developed the musical scale of today.

By golly!

You do find mathematics
in the darndest places.

SPIRIT: You can imagine
how excited Pythagoras was

when he shared his findings
with his pals, a fraternity of eggheads,

known as the Pythagoreans.

(WHISPERIN G) They used to meet
in secret to discuss

their mathematical discoveries.

Only members were allowed to attend.

They had a secret emblem,
the pentagram.

Let's see what the topic is for today.

(PLAYING SOFT MUSIC)

What's going on?

SPIRIT: Shh, it's a jam session.

DONALD: GiVe me
something with a beat.

SPIRIT: Shh!

(PLAYING UPBEAT DRUM MUSIC)

(PLAYING UPBEAT MUSIC)

SPIRIT: So, from these eggheads,
the Pythagoreans,

with their mathematical formula,
came the basis of our music of today.

(PLAYING JAZZ MUSIC)

(PLAYING CLASSICAL MUSIC)

Pythag, old boy, put her there.

Well, I'll be a goshdarn egghead.

SPIRIT: It was our old friend
Pythagoras who discovered

that the pentagram was
full of mathemagic.

The two shorter lines combined
exactly equal the third,

and this line shows
the magic proportions

of the famous golden section.

The second and third lines
exactly equal the fourth.

Once again,
we have the golden section.

But this is only the beginning.

Hidden within the pentagram

is a secret for creating
a golden rectangle,

which the Greeks admired
for its beautiful proportions

and magic qualities.

The star contains the golden rectangle
many times over.

It's a most remarkable shape.

It can mathematically
reproduce itself indefinitely.

All these rectangles have
exactly the same proportions.

This figure also contains a magic spiral

that repeats the proportions
of the golden section

into infinity.

To the Greeks,
the golden rectangle represented

a mathematical law of beauty.

We find it in their classical architecture.

The Parthenon,

perhaps one of the most famous
of early Greek buildings,

contains many golden rectangles.

These same golden proportions
are also found in their sculpture.

In the centuries that followed,

the golden rectangle
dominated the idea

of beauty and architecture
throughout the Western world.

The cathedral of Notre Dame
is an outstanding example.

The Renaissance painters
knew this secret well.

Today, the golden rectangle is
very much a part of our modern world.

Modern painters have rediscovered
the magic of these proportions.

Indeed, this ideal proportion
is to be found in life itself.

DONALD: Boy, oh, boy! Oh, boy!

This is mathematics?

I got mathematical figures like that.

SPIRIT: Ah, ah, ah, Donald.

Let me try it.

SPIRIT: No, no.

Ideal proportion.

SPIRIT: Not quite.

Uh-uh. No, I'm afraid not.

Well, we can't all
be mathematically perfect.

Oh, yeah?

There! I knew I could do it.

SPIRIT: Now that you're
all pent up in a pentagon,

let's see how nature uses this
same mathematical form.

The petunia,

the Star Jasmine,

the starfish,

the waxflower.

There are literally thousands
of members in good standing,

in nature's
Pythagorean Society of the Star.

All nature's works
have a mathematical logic,

and her patterns are limitless.

The magic proportions
of the golden section

are often found in
the spirals of nature's designs.

The profusion of mathematical forms

brings to mind the
words of Pythagoras,

"Everything is arranged according to
number and mathematical shape. "

Yes, there is mathematics in music,
in art, in just about everything.

And as the Greeks had guessed,
the rules are always the same.

Well, Donald, did you enjoy
your geometrical journey?

Gee, Mr. Spirit, there's a lot more
to mathematics than two times two.

SPIRIT: That's right, Donald,

and you can find mathematics
in games, too.

Games? Oh, boy!

SPIRIT: Let's begin with a game
that's played on squares.

- Checkers?
- No.

- Chess.
- Chess?

A mathematical contest
between two minds.

It's a game that has been enjoyed
for centuries by kings and commoners.

In fact, Lewis Carroll,

a famous mathematician
with a literary mind,

used chess as a setting
for his classic tale,

Through the Looking Glass.

Alice found herself face-to-face

with a none too friendly
group of chess pieces.

Good heaVens! What's this?

Upon my soul,
it appears to be a lost pawn.

I'm no pawn. I'm Donald Duck.

He says he's Donald Duck.

Preposterous!

Or, it could be an Alice.

Alice?

No, no, no. It's a lost pawn.

Lost pawn?

Stop that pawn!

Help! Mr. Spirit! Help! Help! Help!

(GROANS)

Whew! That was close.

SPIRIT: Now you can look
at this game from a safer perspective.

Chess is a game of calculated strategy

and since the board is geometrical,
the moves are mathematical.

Checkmate and the game is over.

That's Very interesting. What's next?

SPIRIT: Practically, all games
are played on geometrical areas.

The baseball field is a diamond.

Oh, boy!

SPIRIT: And without mathematics,
we couldn't even keep score.

Football is played on a rectangle
divided by yard lines.

Basketball is a game of circles,
spheres and rectangles.

Even hopscotch has
its multiple squares.

What's next, tiddlywinks?

SPIRIT: No.

A mathematical game played
on a field of two perfect squares,

using three perfect spheres
and a lot of diamonds.

In other words, billiards.

Oh, boy! That's for me!

SPIRIT: You know the game,
don't you, Donald?

Of course, that cue ball has
to hit the other two balls.

Like this!

SPIRIT: Now, let's see
how an expert at three-cushion billiards

uses his head.

DONALD: Three cushion?

SPIRIT: Yes, the cue ball
not only has to hit both the other balls,

but it must contact at least
three cushions before it hits

the final ball.

One, two, three.

One, two, three.

It takes an expert to make
several shots in succession.

One, two,

three, four,

five, six.

Wow! That was a lucky shot.

SPIRIT: Luck? No, it's skill.

For this game,
you have to know all the angles.

DONALD: One, two, three, four, five,

six, seven.

That's amazing! How does he do it?

SPIRIT: First, there's technique.

He's striking the cue ball low

so it'll spin backwards.

Hitting the ball on the right side
will make it hug the rail.

These trick shots take a lot of practice.

(LAUGHING) He missed it!

SPIRIT: One, two,

three.

DONALD: What's so mathematical
about that?

SPIRIT: Oh, this game takes
precise calculation.

He figures out each shot in his head.

He could play it like this,
but it calls for quite a bit of luck.

There is a better choice.

For this he uses
the diamond markings on the rail

as a mathematical guide.

First, he figures the natural angle
for hitting the object balls,

and then he finds that his cue ball must

bounce off the number 3 diamond.

Next, he gets ready for the shot,

and he needs a number
for his cue position.

This calls for a different set of numbers.

DONALD: Very confusing, isn't it?

SPIRIT: Not when
you get the hang of it.

You see, the cue position is 4.

Now, a simple subtraction.
3 from 4 is 1.

So, if he shoots for the first diamond,
he should make it.

It's called playing the Diamond System.

Natural angle, 2.

Cue position, 1.5, 2, 2.5, 3, 3.5.

2 from 3.5 is 1.5.

So, shoot halfway between
the first and second diamonds.

There's nothing to it. Let me try.

Let's see now.

If I hit it here and it bounced there...

And, no, here. If I hit it here...

4.5 minus 3... 3.5 plus 4 added to 2.

Divided into...

I guess I should shoot about here.

SPIRIT: No, no, Donald.
There's no guess work to mathematics.

It's quite simple.
Natural angle for the hit, 2.

Cue position, 3.5.

How much is 3.5 minus 2?

DONALD: Uh, 1.5.

Hey, it works! Oh, boy!

It's a cinch!

If I hit it here...

3.5 plus 4 to 4.5 minus 3...

DiVided by that...

SPIRIT: You're making it
tough for yourself, Donald.

How do you like that
for mathematics, Mr. Spirit?

SPIRIT: Wonderful, Donald.

And now you're ready
for the most exciting game of all.

Oh, boy!

SPIRIT: And the playing field
for this game is in the mind.

Uh-oh!
Look at the condition of your mind.

Antiquated ideas,
bungling, false concepts,

superstitions, confusion.

To think straight,
we'll have to clean house.

There! That's more like it.
A nice, clean sweep.

This game is played
with circles and triangles.

Think of a perfect circle.

A perfect circle.

Perfect circle.

Perfect. Ah!

Put a triangle inside and turn it.

Now, spin the circle
and what have you got?

DONALD: A ball!

SPIRIT: Yes, a sphere.

The shape of things
is first discovered in the mind.

Slice off the top and we have a...

DONALD: A magnifying glass!

SPIRIT: That's right.
A lens is a section of a sphere.

All optical instruments
are created through mathematics.

You see,
there's a lot more to mathematics

than just numbers and equations.

Let's get back to our circle and triangle.

Roll it and we have a...

DONALD: A wheel!

SPIRIT: The circle has been the basis
for many of man's important inventions.

The mind can create
the most amazing things.

If we spin the triangle, we have a...

- DONALD: Cone!
- Slice the cone.

(DONALD CHUCKLIN G)

SPIRIT: The cone is full
of useful mathematical shapes.

Slice it again. Slice it several times.

The orbits of all planets and satellites
can be found in the cone.

No matter how you slice it,
it's always mathematics.

A slice like this gives us
the reflector of a search light.

A slice like this,
the mirror of a giant telescope.

A line on a cone and we have a drill,

and a spring.

Now you're ticking.

(TELEPHONE DIALING)

OPERA TOR: Number, please.

(TRUMPE T MUSIC PLA YIN G)

(ENERGETIC MUSIC PLAYING)

SPIRIT: The mind is the birthplace
for all of man's scientific achievements.

The mind knows no limits
when used properly.

Think of a pentagram, Donald.

Now, put another inside,
a third and a fourth.

No pencil is sharp enough
to draw as fine as you can think,

and no paper large enough
to hold your imagination.

In fact, it is only in the mind
that we can conceive infinity.

Mathematical thinking
has opened the doors

to the exciting adventures of science.

I'll be doggone!

I'Ve never seen so many doors before.

SPIRIT: Each discovery leads
to many others.

An endless chain.

Hey! Hey!
What's the matter with these doors?

Hey! These doors won't open.
They're locked!

SPIRIT: Of course, they're locked.
These are the doors of the future,

and the key is...

Mathematics!

SPIRIT: Right. Mathematics.

The boundless treasures of science
are locked behind those doors.

In time, they will be opened
by the curious and inquiring minds

of future generations.

In the words of Galileo,

"Mathematics is the alphabet

"with which God has
written the universe. "
