The Big Bang Theory, Season 6

Sheldon:
[arriving with Alex] Oh, good, Leonard, you're here. Science news. This will interest you. And, Penny, feel free to paint your nails.

Leonard:
What do you got?

Sheldon:
I believe Alex may have unearthed the grade school science project that could be my ticket to the Nobel Prize. Behold.

Leonard:
Magnets: What Do They Stick To? If the answer is metal, it's not exactly groundbreaking.

Sheldon:
The original title was "A Re-derivation of Maxwell's Equations Regarding Electromagnetism" I dumbed it down because some of the more religious people in town were starting to say I was a witch.

Alex:
Sheldon thinks the approach in this paper might change the way we calculate ferromagnetic hysteresis.

Penny:
Oh, it's about time. I hated the old way. Hi. I'm Penny.

Alex:
Alex. Uh, do you work with Dr. Hofstadter?

Penny:
In a way. We've kind of been involved in a five-year experiment.

Alex:
Oh. Well, you're lucky. He seems very talented. And I'm sure a lot of people want to work with him.

Penny:
Well, a lot of people can't. Uh, hey.

Leonard:
Where are we going?

Penny:
My limbic system wants to take your pants off.

Alex:
She seems nice.

Sheldon:
Notice people on your own time. We're working.
