I’m about to embark on one of the great challenges of my scientific career: teaching Penny physics.

Calling it “Project Guerrilla.”

Penny: Hey Sheldon.

Sheldon: Come in. Take a seat. Thinking Subject has arrived. I’ve extended a friendly, causal greeting.

Penny: Ready to get started?

Sheldon: One moment.

Thinking Subject appears well rested and enthusiastic.

Apparently ignorance IS bliss.

Speaking All right. Let us begin. Where’s your notebook?

Penny: Umm, I don’t have one.

Sheldon: How are you going to take notes without a notebook?

Penny: I have to take notes?

Sheldon: How else are you going to study for the tests?

Penny: There’s going to be a test?

Sheldon: Tests.

Here. That’s college ruled, I hope that’s not too intimidating.

Penny: Thank you.

Sheldon: You’re welcome. Now, “Introduction to Physics.” What is physics?

Physics comes from the ancient greek word “physica.”

It's at this point that you'll want to start taking notes.

Physica means “the science of natural things,” and it is there, in ancient Greece, that our story begins.

Penny: Ancient Greece?

Sheldon: Hush. If you have questions, raise your hand. It’s a warm summer evening, circa 600 BC.

You’ve finished your shopping at the local market, or “agora.”

And you look up at the night sky, and there you notice some of the stars seem to move.

So you name them “planitace,” or wanderer.

Yes penny?

Penny: Does this have anything to do with Leonard’s work?

Sheldon: This is the beginning of the 26 hundred year journey we are going to take together.

Fom the ancient Greeks, through Isaac Newton, to Niels Bohr, to Erwin Schrödinger, to the Dutch researches that Leonard is currently ripping off.

Penny: 26 hundred years?

Sheldon: Yes, give or take. As I was saying: It’s a warm summer evening in ancient Greece. Yes Penny?

Penny: I have to go to the bathroom.

Sheldon: Can’t you hold it?

Penny: Not for 26 hundred years.

Sheldon: Thinking Project Guerrilla, entry two. I am exhausted.
