_________________________________________________

Pi Day is celebrated on March 14th (3/14) around the world. Pi is the symbol used in mathematics to represent a constant - the ratio of the circumference of a circle to its diameter - which is approximately 3.14159.

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi's infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

The earliest known official or large-scale celebration of Pi Day was organized by Larry Shaw in 1988 at the San Francisco Exploratorium with staff and public marching around one of its circular spaces, then consuming fruit pies. The Exploratorium continues to hold Pi Day celebrations.

March 14 is also Albert Einstein's birthday.

The first calculation of pi was done by Archimedes of Syracuse (287-212 BC), one of the greatest mathematicians of the ancient world. For further interesting facts about pi, visit this website:

Oh Pat I haven't had a chance to catch up with your puzzles in the past few days, but beef and chicken pot pit sounds delicious!! I hope you're not still hungry!!

Yes, whatnauts, I agree, Google is wonderful for looking things up on - and yes, shepherd's pie and cottage pie don't use pastry, so they are nice and healthy!!!

whatnauts

Wow, I never heard of fidget pie before. Thank goodness for Google. I do enjoy shepherd's pie from time to time, but I don't use pastry for that, so I tend not to think of it as 'pie'.

pdevredis

Ah, on my own puzzle I mention beef and chicken pot pie as preferable to a fruit-filled one! And now I'm hungry again, even though I just ate breakfast.......

monza006

Its nice to know you enjoyed the fun whatnauts, and you can celebrate with delicious fresh fruit... I won't tell!! :~)

monza006

Yes, I noticed that too Wendy.... although no-one said they preferred a savoury pie!! What about Fidget Pie, Shepherd's Pie or Steak and Ale Pie??? Nice to see you today :~)

whatnauts

Thanks for this fun puzzle, monza. I'm skipping the pie and celebrating with fresh fruit!!

Skimming through the comments, I'm pleased to note that Jigidiers are in tune with the true meaning of Pi day. As for me, almost any pi is fine, especially warm apple pi with a good vanilla ice cream on top.

Thank you all so much for the lovely comments on this puzzle, and I hope you all enjoyed celebrating Pi in the way best suited you and your waists! I have another early start tomorrow, which prevents me from responding to you all more fully as I would prefer. :~)

Mandy - thank you for our daily fix of interesting things. I like and underscore Brie1648's comment : "I measure Pie by the number of inches it adds to my waist!!" :-)))

Mandy, thanks for your 'who knew' series - always interesting, as is this one.

oldiepumpkin

Well, frankly Mandy, you have lost me there. Maths is not my thing. I prefer also pie to pi. But thanks for the education. One is never too old to learn.

Brie1648

Great one JiggyBelle - I measure Pie by the number of inches it adds to my waist!!

JiggyBelle

My husband, the physicist, LOVES the concept of the day. Obviously for Einstein's B'Day, but also for the measurement and appreciation of Pi.
I appreciate and measure PIE in another way entirely - chocolate pecan, for example!

Elfie

Indeed I would like to celebrate Albert Einstein - and of course Pi, even if I never understood much of it!! Thanks so very much Mandy!!

Thank you! I especially like the pi-shaped pie.

I'd forgotten about this. It's been a few years since I taught math. But I celebrated pi day with them. I gave a math teacher friend a sweatshirt that said Pumpkin with the pi symbol. It was bright orange. Thanks, Mandy, for this reminder and for some fun memories.

Very cool puzzle to celebrate Pi day Mandy!

Brie1648

Lemon meringue would be good too. I suppose, technically, it is not a pie because it doesn't have a lid..but neither does key lime...hmmm
Does pi ever finish...if a circle is a polygon of an infinite number of straight lines its never going to end....the current "record" for digits of pi solved stands at 51.5396 billion decimal digits; set by Yasumasa Kanada.
I'll have to think about this over a big piece of apple pie!

Surreal_Heidi

My favorite is blueberry pie. I'll have a nice big slice, please, but only if it's freshly baked.

I'm with Barb on this one. I'll take a nice piece of cherry pie any day and by the looks of the puzzle people have baked pies to commemorate the day. Thanks for this cute 'quickie' puzzle Mandy

pdevredis

I've been seeing mentions of this on Jigidi all week, and now that I see your puzzle, I wonder if that's why I (subconsciously) chose to post a "Pie" puzzle today! LOL! I think I'll celebrate Einstein's birthday as well--it's just as important, relatively speaking..... :-)))

Very interesting Mandy thanks

Interesting puzzle.......thank you.

tigress

Only a mathematician would appreciate this day, Mandy. I think I would prefer 'PIE' day. :-)))
Thanks for another Who Knew puzzle. :-)
