Today has the date 22/7, which makes it Pi day. To celebrate this occasion, someone gave me the pi dish shown in the thumbnail. It has pi to 88 decimal places around the rim.
(For those who are interested in such things, the approximation 22/7 is only correct to 3 dp)
Yes I am PIning. It was clear last night (only after I finished drinking), and was 'sposed to be sunny today, but there is all this crappy high cloud just in time to ruin tonight
A wonderful gift and talking piece. I think everyone has a fascination with pi.
22/7 is accurate to 3 digits. A rather less known but better approximation for pi is 355/113 (accurate to 7 digits). The fraction has the odd sequence starting from bottom 113 then 355 (two 1s, two 3s, two 5s).
Today, pi has been calculated to over one trillion digits.
11 decimal places is sufficient to calculate the length of the Earth's Equator to the nearest mm and 29 decimal places would give the circumference of the observable Universe to the nearest mm.

Hi Rob,
How many decimal places to calculate a Macca's quarter pounder to the nearest mm?
