Endless Pi

Pi DayIn school, we are used to 3.142 as the number for pi. We also know that the number goes on and on. How far on? In 2016, a Swiss scientist used a computer to try to calculate pi and ended up with 22 trillion digits. In case you are wondering, 22 trillion is 22,000,000,000,000.

And that was not even the end of pi.

The furthest that a human has got in terms of memorising pi is up to 70,000 decimal places. That was achieved by Rajveer Meena from India in 2015.

Pilish – The Language of Pi

Ok, we decided to round up the number of facts from “3.14” to “4”.

The bonus fact about Pi is that there is a constrained style of writing developed around Pi. This is a way for word nerds (like ourselves) to also get in on the pi action

In Pilish, the number of characters in each word has to match the digits in pi. For example, the sentence “How I need a drink, alcoholic in nature, after the heavy lectures involving quantum mechanics!” matches the first 15 digits of pi.

If you are wondering how far this idea can be carried? There has been a full length Pilish novel with 10,000 digits published.
