Google is geeky cool.

Have you ever wondered what, exactly, "once in a blue moon" really means?

Try this:

Go to google's search page and enter:
Once in a blue moon
as your search term.

The result:

1.16699016 × 10-8 hertz

That is, once every 10 to the negative 8 seconds. Or, to better under stand the result, enter this:
1/(once in a blue moon). You get 2.71542689 years. That is a blue moon (two full moons in one month) happens once every 2.71... years.

Or, try this:

(number of horns on a unicorn + the answer to life the universe and everything) / once in a blue moon


e^(i*Pi) + 1

(0), which is correct and happens to be one of the coolest identities in all of mathematics.

e^(i*Pi) + 1 = 0

This is called Euler's equation. It uses five of the most important constants in mathematics and the mathematical sciences (e, Pi, i, 1, and 0). It also uses three of the most important operations (addition, multiplication, power) and THE most important relation (=). I've already mentioned this, but it's such a cool equation that you need to see it again and again. :)
