Happy pi day!


Okay, it’s not about any pie, it about pi, π, my favorite mathematical symbol or constant. It’s the first Greek symbol I was acquainted with and I’m in love with it ever since. And no other fancy symbol can ever take it’s place. How could I possibly not write a post about it today, The Pi Day. No, sir, I’m not kidding. Today, march 14th (3-14) is celebrated as Pi Day all over the world.  The official celebration begins at 1:59 p.m., to make an appropriate 3.14159 when combined with the date. And I’m strangely super-excited today. My e-mail id has the number “314” in it; I own a pendant with pi made on it. Here, have a look:

Sorry, I don’t have a high quality phone camera, so please bear with me. Incidently, it is a gift I got just a few days ago. I don’t think there could have been be a better timing of getting it. Really, this is just so awesome (btw, it is my choice, I asked my friend to gift it to me.. 😛 oh yes, I’m that shameless at times.) I wore it today for the first time, out of sheer excitement. (I never wore a pendant in my entire life before except once, on a cousin’s wedding day.)  I have been always been intrigued by the story of Pi, no, I don’t mean the male protagonist of the Oscar-winning movie , Life of Pi.

Let me tell you some facts:

-> Believe it or not, it the coolest of all the mathematical constants there are.

-> Its common definition is the ratio of the circumference to the diameter of a circle, but there are a plenty of more definitions too.

-> It is an irrational number, i.e., no matter how accurate we calculate its value, there would be no pattern of digits found whatsoever. The first 100 decimal digits of π are: 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74944 59230 78164 06286 20899 86280 34825 34211 70679…


(Well, this happens to be my favorite joke, couldn’t resist including it.)

->It is also an transcendental number, meaning no polynomial equation having rational constant coefficients can have π as a solution.

-> The most commonly used approximate value of π is 3.14 or 22/7, which we’re normally taught in high school, but even more accurate approximate rational numbers are:  333/106, 355/113, and more.

-> It is the title of an awesome 1998 thriller movie. 😛 (just kidding)

-> Albert Einstein was born on Pi Day (3/14/1879) though Pi Day is being celebrated only since 1988. (I’d have felt so glad, had it been my b’day too, but alas!)

-> 3.14 backwards is PIE.

-> Another π joke:  “What is the volume of a pizza of thickness a and radius z?” Answer: pi z z a. (not funny enough, eh? I bet you’ll laugh at the next one.)

-> In the Star Trek episode “Wolf in the Fold,” Spock foils the evil computer by commanding it to “compute to last digit the value of pi.” Isn’t it magnificent?

-> A Web site finds a person’s birthday and other well known numbers in the digits of pi. Here:


I won’t stop, you know, I’m hysterical right now. I’m gonna get similar π earrings too very soon.
