International pi day is March 14, the 14th day in the 3rd month... 3.14!

Why do we need a number to calculate the area and circumfrence of a circle? Why isn't it just as easy as measuring a rectangle? If you want to find the area of a rectangle, you multiply the shorter side by the longer side. Finding the perimeter is even easier. All you need to do is measure around the outside of the shape. But you can't multiply the sides of a circle, because they don't even have sides! And you can't measure around the outside of a circle with a ruler, because rulers are straight. That is why we need pi.

We will learn pi at school in grade 7.

Comedian John Evans once said: “What do you get if you divide the circumference of a jack-o’-lantern by its diameter? Pumpkin pi.”

In the Star Trek episode “Wolf in the Fold,” Spock foils the evil computer by commanding it to compute to the last digit of pi. Pi is infinite.

Another reason why pi is so special is that it can be used in many different equasions. Sure, people can figure out a number to calculate something, but pi is so special because the exact same number can be used for many geometry equasions.

Since there are 360 degrees in a circle and pi is intimately connected with the circle, some mathematicians were delighted to discover that the number 360 is at the 359th digit position of pi.

The first 144 digits of pi add up to 666 (which many scholars say is “the mark of the Beast”). And 144 = (6+6) x (6+6).

The equasion for finding the area of a circle is 'r2 x π = a'. It means 'radius squared times pi equals area'.

The equasion for finding the circumfrence of a circle is 'd x π = c'. It means 'Diameter times pi equals circumfrence'.

Here are the first 50 digits of pi: 3.14159265358979323846264338327950288419716939937510

In the Greek alphabet, π (piwas) is the sixteenth letter. In the English alphabet, p is also the sixteenth letter.
