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)

Geoff,

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.

Regards, Rob

I tried one of those. No matter where I went it felt as though I was driving in circles. :whistle:

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

Hi Marty,
You'll have to be more specific. Is it beef or kangaroo?

Some of you might have heard this funny anecdote about PI.
I found it on a blog years ago:

One professor said he came into class one day with a black eye
and when questioned over it, he said, "well me and the faculty scientists
were having an argument over which was the more fascinating
mathematical constant...PI or E which is the Hubbles constant for
the expansion of the universe".
He said the argument got quite heated and he had to take a stand for
PI....

Please tell me you didn't just laugh....
umm because I didn't...
Honestly. :)
