A young friend, middle 30s, approached me with a bit of spooky (to him) information. It seems that when pi ( "π")--3.14--is written on a piece of paper and held up to a mirror, it reads "pie." Now, this information was presented in the same vein as listening to music played backwards, some sort of satanic or mystical message. ???
Pie/pi/ "π" Day is March 14--3.14
I wrote 3.14 and held it up to a mirror. No, it approximates "pie."
I wrote 3.14159, held it up to the mirror, and it was nothing. This was just silliness on my part.
First of all, 3.14 is not all of pi. It is a shortened version that we just use so we won't have to use 67,000+ numbers in a simple calculation. I use 3.14159 or 3.1416 for "π". So far, no one has found that pi ( "π") is a repeating number, just still an irrational number.
I really worry when religion tries to make a mystical connection to John 3:14 (For God so loved the world...), the ratio of a circumference to diameter of a circle, pi, and pie viewed backwards. That is hard work and lots of mental gymnastics--the world is round, the center of the circle for the radius is God, 3 is the trinity.
Did you celebrate Pie Day? I love it. Kids will at least talk math for one day.
