A Delicious Slice of Pie. Wait – I Meant π!

Happy belated π day! To start up, here are some amazing facts about and around π that you definitely need to know RIGHT NOW:

  • Chinese man Chao Lu memorised 67,890 digits of π in 2005. Seems like somebody’s got so much time in life!
  • Calculating π is used as a stress test in computers – I’d say it’s a stress test for all beings in the world don’t you agree with me?
  • “Wolf in the Fold”, the Star Trek episode, Spock spoils the evil computer by commanding it to, compute the last digit of π value. The geekiest way to defeat a bot.
  • π is defined as the ratio between a circle’s circumference and its diameter.
  • You can type π (like me!) in a Macintosh simply by pressing the alt button simultaneously (yes, simultaneously because…maths.) with p. Now let the πππππ roll in!
  • π is considered to be the most significant and intriguing constant, as mentioned by numerous scholars.

However, why do we even care about the existence of pi, then? In simple words, not everything in this world, both stationary or moving, are geometrically straight. Any form of curvature, to be measured more accurately, needs this irrational number π. Even if we are unable to get the true value of anything that is related to π as it is an irrational number, we are able to get the closest value and calculation of things almost perfectly despite this inexact constant.

I personally found Archimedes’ way of calculating π as the most interesting of them all as it invokes to me so many thoughts. He calculated π but drawing a hexagon inside of a unit circle, and calculated the ratio of the perimeter of the hexagon to the diameter of the unit circle. Then, he did this until he got up to 96 sides – meaning that the number of sides for the polygons he used were the numbers in the sequence an= 2an-1 where a0 is 6, and 0 ≤ n ≤ ∞. This makes me think – is a circle really a shape with no sides, or perhaps a shape with infinite number of sides?

π is delicious useful in our daily lives even though it may seem totally irrelevant in such a capitalistic society. Nevertheless, underestimate not the power of such a simple constant and the beauty it brings to the world! Once again, have a belated happy pie π day everyone! *stomach grumbles*
