About Pi – An Interesting Number
One of the really neat things about mathematics is Pi.
Here is an explanation from Wikipedia:
The number (/pa?/) is a mathematical constant that is the ratio of a circle‘s circumference to its diameter. The constant, sometimes written pi, is approximately equal to 3.14159. It has been represented by the Greek letter “” since the mid-18th century. is an irrational number, which means that it cannot be expressed exactly as a ratio of two integers (such as 22/7 or other fractions that are commonly used to approximate ); consequently, its decimal representation never ends and never repeats.
I usually feel safe (LOL) using 3.1416 whenever I am calculating or working on problems involving Pi.
So many people have dedicated their lives to the exploration (for lack of a better word) of Pi.
So many books have been written about Pi.
One of my favorites is The Joy Of Pi.
The book has pages of funny stuff about the subject.
And some really cool jokes.
I highly recommend you go to the book’s website: JoyOfPi.com
There, you will find some neat facts.
March 14 is Pi Day.
It also happens to be Albert Einstein’s birthday.
(It’s also my late Dad’s birthday.)
Larry Shaw, a physicist, founded Pi Day in 1988.
Here are some Pi jokes and riddles:

The mathematician says, “Pi r squared.”
The baker replies, “No, pies are round. Cakes are squared.”
Come to the nerd side.
We have pi.
Q: What do you get when you take the sun and divide its circumference by its diameter?
