You all know Pi, right? The circumference of a circle divided by its diameter? The answer is the same for any circle – a math constant, usually rounded to 3.14159. Did you know that a guy named Chao Lu recited 67,890 decimal places of pi? It took him 24 hours and 4 minutes (with no break). He’s the current official record holder. He had actually spent a year memorizing 100,000 digits, but messed up when he got to the 67,891st number. Damn. I should send him one of our cool hats.

My maths teacher used to celebrate the Pi day every year in France, making a song about Pi where each word had the number of letters of the corresponding Pi decimal (3 for the 1st word, then 1, then 4…). With a host of french puns about Pi-containing words as well (he brought Pie, Pizzas, Pinard wine, a Kepi hat)…

But I never saw such a great hat for the Pi day, even though I’ve celebrated lots of Pi days!!

And for those who missed the Pi day, the Pi approximation day exists on July the 22nd, as 22/7 is close to Pi.

Cheers

crazywhen we loudly started a 10 second countdown!
