July 22 is Pi Approximation Day. Celebrate with a Pi!


July 22nd:

July 22nd (international numeric date is 22/7/year) is Pi Approximation Day and celebrates the discovery of the calculation of the Math Symbol Pi – which is approximately calculated at 22/7 (22 divided by 7).

Peter Kevin Connell from Today in Heritage History warns:

“Please be courteous driving today and try to avoid all the International Mathematician Parades. Most mathematician marchers generally have problems negotiating traffic while dressed in Rhombus and Trapezoid costumes.”

May 14th:

May 14th is what is typically known as Pi Day, and is an unofficial holiday commemorating the mathematical constant p (pi). Pi Day is celebrated on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of p in the decimal form. In 2009, the United States House of Representatives supported the designation of Pi Day.


What is Pi?

The simplest visualization of Pi is probably a circle.

Half the circumference of a circle with radius 1 is exactly Pi!
The area inside that circle is also exactly Pi!

  1. I LOVE pie!!! Apple pie, Cherry pie, Blueberry pie, just about any kind of pie! Mmmm… I wish a had a big slice of pie right now!

    So is it like some cool and hip new thing to drop the E off of the spelling of “pie” now? Hey, whatever… I tend to be a bit of a language purist, having been an English/Journalism major in college, who graduated with a 3.57 GPA. but I’m not gonna get all condescending and huffy about it right now, cause I’m in a good mood, and I don’t want to get obnoxious about such a trivial thing here.

    Now mathematics was another story for me… I had to take remedial Algebra just to get through my freshman year in college. Hey, we all have our different strength and weaknesses… Right?

    Oh BTW, I don’t know what they have to do with pie, but those are some interesting recurring symbols you have on the series of images here. Like something very mysterious and unknown… but cool!

    Well, that’s it… See what you’ve done Michelle? I’ve just gotta go out and buy me a nice big pie, and I’m leaving right now!

    LOL 😀

  2. I don’t need no (stinkin’) Sunshine Award…I’ve been quoted at Motley News. I’ve seen the Grand Canyon, a sunrise from Newark Airport over the New Jersey Budweiser plant, and now this.My life is complete :). All ill-humor aside thank you so much Michelle! I am truly honored and humbled.

    • LOL… I started reading that and I’m thinking, “Did I give him a Sunshine Award? I didn’t give him that! Did he get me confused with someone else?” Then I caught on. And, yes… I just woke up from a nap so my brain cells haven’t started snapping just yet.

Go ahead... I can hear your thoughts. Please share with the rest!
