Quantum Physics


Hi all — here’s my take on the “Twisted Children’s Shows” edition of Sketchwar.

FADE IN: 

INT. LAB – DAY

Note: this is all animated. Think “Schoolhouse Rock.”

VINH, a little boy, approaches DR. PHYSICS, an old scientist in a lab coat.

VINH

Dr. Physics?

DR. PHYSICS

Yes, Vinh?

VINH

I heard about something called “quantum physics” -- but I don’t know what it is!

DR. PHYSICS

Well, then, Vinh -- let me introduce you to a friend of mine!

The HAMILTONIAN -- an excitable little poofball of fire with arms, legs, and googly eyes -- appears.

HAMILTONIAN

Hey, Vinh, let’s start by looking at the finite barrier quantum well!

VINH

The what?

He takes Vinh’s hand and they start flying away --

VINH

I don’t want to go in the well!

Poof! They appear in --

INT. FINITE-BARRIER WELL – NIGHT

-- a deep well illuminated by glowy shapes.

VINH

Who are you?!

Music starts up. [It will continue throughout.]

HAMILTONIAN

(singing)

I’m a Hamiltonian, the system’s energy / Potentials and derivatives together equals me! / And if it never changes, then the answer’s gonna be / Somethin’ that we’re about to see!

Meanwhile, Vinh bangs on the walls.

VINH

Stupid! Finite! Barrier!

Some unseen BACKGROUND SINGERS start singing.

This frightens Vinh.

BACKGROUND SINGERS (O.S.)

The wavefunction’s time derivative / Equals the wavefunction’s second spatial derivative / Plus the wavefunction times potential e-ner-gy! / It’s as easy as that!

VINH

Where are those voices coming from?

HAMILTONIAN

No time for that, little Vinh. We’ve got to introduce you to my friend!

VINH

I don’t want to meet your --

A little matrix appears -- the EIGENVECTOR. Again, it has arms, legs, and googly eyes.

EIGENVECTOR

Hi, Vinh!

VINH

What is that?!

The screen stretches, skews, and distorts.

Everything but the eigenvector stretches with it.

Vinh does not like being distorted.

VINH

AAAAH!

EIGENVECTOR

(singing)

I’m a math solution, eigenvector is my name! / And under transformations, my direction stays the same!

VINH

Stop stretching me! Ow! OW!

EIGENVECTOR

(singing)

I solve the Hamiltonian, and that’s my claim to fame, / But that’s just part of the game!

The screen stops distorting.

EIGENVECTOR

And that solution is called “eigenenergy.”

VINH

Eigen-what?

EIGENVECTOR

Now you’re getting it!

VINH

No I’m not!

BACKGROUND SINGERS (O.S.)

The eigenergies are quantized solutions / To the reduced eigenequation / Of the original Hamiltonian / It’s as easy as that!

Vinh looks around in vain for the singers.

VINH

What’s a reduced -- what?

HAMILTONIAN

I’d say he’s still confused.

EIGENVECTOR

Time to bring in the big guy.

VINH

I don’t want to see the big guy!

A giant mass of mathematical symbols -- Schrödinger’s EQUATION -- floats down. Again: arms, legs, googly eyes.

EQUATION

(singing)

I’m Schrödinger’s equation, Vinh, and here’s what I equate: / How a system over time will change around its quantum state / I can tell you where it started and I know about its fate / Quantum physics is great --

EVERYONE BUT VINH

(singing)

And it’s as easy as that!

Poof! The well and its denizens disappear.

INT. LAB – DAY

Vinh falls down to the floor next to Dr. Physics.

VINH

Ow!

DR. PHYSICS

Do you understand now, Vinh?

VINH

No! It’s weird! And it makes no sense to me!

DR. PHYSICS

Don’t worry, Vinh.

He pats Vinh on the back.

DR. PHYSICS

Quantum physics makes no sense to scientists, either.

BACKGROUND SINGERS (O.S.)

It’s as easy as that!

FADE OUT.
