What does the word ‘pie’ bring to your mind? A melt-in-the-mouth crust on the outside with a sweet filling in the middle? Well, there’s another ‘pi’ too which is pronounced more or less the same but spelt differently.

And it goes on and on. Looks familiar? Well, we’ve all encountered it at some point or the other in our lives, the ubiquitous 22/7 which had a bad habit of cropping up in math problems. Well, this number that basically never ends has a whole day dedicated to it every year – March 14.

Fascinating, eh? To me, yes. As for my kids, they haven’t encountered the ‘pi’ in their math world yet, but soon will.

- The circumference of a circle divided by its diameter is equal to pi.
- ‘Pi Day’ was first celebrated on March 14, 1988 by physicist Larry Shaw.
- How is March 14 (Pi Day) written as a date in the US? 3-14.
- Co-incidentally (or otherwise), Albert Einstein’s birthday also falls on this great day (or vice versa).
- Beyond the decimal point, the value of pi has been calculated to over one trillion digits.
