(CNN) — Today is a very special one for math lovers, and it only comes around once a year.
It’s pi day!
Who doesn’t like pie?
Whether it’s an old-fashioned apple pie…
The Oscar-winning Life of Pi.
A pepperoni pizza pie.
Unless it’s a slice of humble pie, it brings us together!
Of course, if you drop the ‘e’ on it, you’ll drop some of the enthusiasm.
But the true mathletes out there can always bake up a little fun on “Pi Day.”
It’s celebrated every year on March 14.
That’s 3-14, as in the first few digits of pi. The ratio of a circle’s circumference to its diameter.
You could call our fascination with it, irrational.
And that’s just the kind of number it is, an irrational one: it just goes on and on, without stopping or repeating… at least as far as we know.
Computers have calculated pi to its two-quadrillionth digit.
Don’t ask the author what that means; he majored in telecommunications.
What he can tell you is that when it comes to this ratio… the pi’s the limit.
