Happy Pi Day!

Today, March 14, is celebrated by geeks worldwide as Pi Day. Pi, as you doubtless all know, is an irrational number (no end to the digits) that represents the ratio of a circle's circumference to its diameter. It begins 3.1415926535 and that's as far as I go.
Post a coin that's related! It could be a three cent piece, one ending in 3 or 14, be creative! And enjoy free Pi in some restaurants.
Kind regards,
George

@1630Boston Good job! I was thinking, a good estimate of Pi is 22/7. A better one, freakishly close to the exact value (less than a third of one-millionth difference), is 355/113 ...

No Pi... but I do have 3146 wheat cents in a jar....
Actually, I do not know the exact count, however, it is close.. I know there is over $30 ....Cheers, RickO
The formula for the area of a circle is pi r squared. However, it is my experience that pi r round, cornbread r square.

Happy Pi day.
Have a slice of pie.
It’s got 3-1-4 in it. It’s “half” of what it used to be now that it’s a pick , and still, pi makes up half of “pick”.
Today is my "adopted" grandson's birthday he was born on pi day 3-14-16 (rounded to 4 decimal places).
Beat me to it.
Got a pi in the sky pic?
No, but I have a ring in my ear, and it's not even pierced. Too much heavy metal, I suspect... Bajj.
I'm not so sure about "worldwide". Much of the word does not follow the month/day convention of the US. It was just unexciting 14/3 here (yesterday).
Smitten with DBLCs.
I couldn't resist posting this here from another Pi thread:
"I've always had a problem with the "Pi R Squared thing" statement. Don't get me wrong.
I always thought that "Pi R Round..........Cornbread R Squared"."
Enjoy your Pi today.
Pete
My recent purchase...
So, you turn the circle backward, whaddya got? A circle.
No, seriously, folks, take my wife. No, really ... I did realize after I casually typed the "worldwide" above that is was a slight exaggeration. But you can celebrate Pi nonetheless, er, yesterday, if you like.
Kind regards,
George
As @toyz4geo said "pi r squared" but I say coins r round.
Small cheese pizza for $3.14 at Mellow Mushroom today.
it's crackers to slip a rozzer the dropsy in snide
@giorgio: Agreed! Just couldn't resist the wind-up!

@crazyhounddog I love that Buffalo! What an absolutely hammered strike!

The Newman Portal indicates that pi was invoked in order to demonstrate that the Barber quarter has a disproportionately smaller bust than the Barber half:

I was hoping to see a planimeter used to calculate the area of Liberty's head.

Far more important that a mere numeric system coincidence, March 14 marks the birth of Albert Einstein and the death of Stephen Hawking.
I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road. Stephen Hawking "“Black Holes and Baby Universes and Other Essays.” 1993.
So wouldn't the best time for the geeks to celebrate Pi day be at 1:59:26 either AM or PM?
Never talk to pi. He'll go on forever
Do we really need that many numbers for Pi?
If the circumference of the earth were calculated using π rounded to only the ninth decimal place, an error of no more than one quarter of an inch in 25,000 miles would result.

Thirty-nine decimal places of pi suffice for computing the circumference of a circle girding the known universe with an error no greater than the radius of a hydrogen atom

A friend of mine is an engineer. He owns a small heat treating plant of 75 or so employees.
Every year on March 14th he has “Pie Day” and a local bakery brings enough pie to feed everyone on all shifts.
