Yes, I know that picture has nothing to do with the number pi. Unless you count the fact that pie is circular, and pi has to do with circles…I like pie, okay?
Today’s post is a short list of facts about Pi Day. Did you know today is Pi Day? Pi is simplified as 3.14, and today is…3/14! (Unless you follow the DD/MM/YYYY format, in which today is 14/3.)
My favorite number is pi. I found myself fascinated by it in ninth grade when there was a poster in my geometry teacher’s room that went over 40 digits. It was right there, on the wall, just begging to be memorized…so I memorized it.
Yes, I memorized it.
I thought that was a huge mental feat, memorizing over 40 seemingly random digits of pi. I was so into the number that I went to my town’s Pi Day celebration at one of the other high schools. There, I learned that others were also into pi and some had memorized far more digits than I had. There were kids as young as 5 competing in contests where they’d recite pi for at least a hundred digits on stage.
I was in awe of them. Wow.
I may not know over a hundred digits (it’s closer to 60 now), but I still enjoy knowing random facts about the number pi. Here are some of my favorites:
- The number pi is used to represent the circumference of a circular object. Those who studied pi discovered that circular objects are always just slightly over three times their width around. If a circle’s width is represented by “d” (the diameter–the distance across the circle), then the circumference (the distance around the circle) is calculated as π*d.
- 3/14/16 is, in my opinion, the ultimate Pi Day. The first six digits of pi are 3.14159, which rounds up to 3.1416, aka 3/14/16. Best pi day ever! Some argue that last year’s Pi Day was the ultimate one, but I disagree.
- Somebody made a song combining pi and music where each digit represents a specific scale degree.
- There’s also another pi song where somebody sings the numbers of pi. It’s catchy and could help you memorize some of it to impress your friends.
- 3.14 backwards looks like PIE.
- March 14 is Albert Einstein’s birthday. How cool!
- If you need a shortcut to calculate pi for mathematical use, use 22/7. It’s not accurate, but close enough for the calculations you might doing.
I hope you enjoy your new knowledge about the number pi! Now go enjoy some p-i-e!
