Pi (π) has been known for almost 4000 years. I learned today that we owe our gratitude to Archimedes of Syracuse (287–212 BC), as being the first to introduce the calculation. Without doubt, Archimedes of Syracuse was the greatest mathematician of the ancient world.
According to the Math is Fun website, Pi is defined as “the ratio of a circle’s circumference to its diameter. In other words: all the way around a circle divided by all the way across it.The symbol is π. No matter how large or small the circle, its circumference is always π times its diameter.”
There is another definition from Michael Emerson as Harold Finch, in the TV Series “Person of Interest” that brings out the humanity held within the numbers.
“Pi, the ratio of the circumference of a circle to its diameter, and this is just the beginning; it keeps on going, forever, without ever repeating. Which means that contained within this string of decimals, is every single other number.
Your birthdate, combination to your locker, your social security number, it’s all in there, somewhere. And if you convert these decimals into letters, you would have every word that ever existed in every possible combination; the first syllable you spoke as a baby, the name of your latest crush, your entire life story from beginning to end, everything we ever say or do; all of the world’s infinite possibilities rest within this one simple circle.
Now what you do with that information; what it’s good for, well that would be up to you.”
