If you are a math nerd, then you probably know all about Pi Day – No, not that kind of pie...
It's the mathematical kind of pi.
No... that's closer, but not the right kind of pie either
What on Earth is Pi?
Pi is the ratio of the circumference of a circle to its diameter.
It looks like this:
OK, backing up.
See this circle?
If you cut this circle in half with a string, then that string from edge to edge of the circle, is the diameter.
Now see how many diameters it will take to go all the way around the circle.
OK, I'll just tell you - the answer is pi.
Now Pi is a real number, but it is actually very long. How long?
According to the official Pi Day website, it has been worked out to a trillion digits.
But really the number goes on forever... or at least mathematicians think it does – it's never been found to quit.
So, to simplify things, most people just use 3.14 as pi.
So why is March 14 (3-14) Pi Day? Do you really have to ask?
No, the real question is:
How much pie are you going to eat on Pi Day?
Let me know in the comments!
I write about, with, for, and around kids all day. (Well, maybe I do the dishes too. Sometimes.)
