On math. Delicious math.

[We have been talking a lot about the speed of light, which is a constant value.]

Are there other mathematical constants?

Yes. There’s a cool one called pi that helps us figure out the circumference and area of any circle. Would you like to do some work with it sometime?

YES YES BRING ME THE CONSTANT PIE!

[Later]

Pi is also cool because it goes on forever. You can’t write it as a simple fraction – its decimals go on forever if you don’t round it – which, clearly, you have to at a certain point. That’s called an irrational number.

CONSTANT ENDLESS PIE! YUMMMMMMMM
