Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) 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.

It 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 memorise, and to computationally calculate more and more digits.

So for a little bit of fun, Mandy Naylor (maths department) decided to challenge some of her College students.  In a lesson this morning she gave them the chance to see how many digits they could memorise and write down.   There were some amazing results from the students, putting even the Maths teachers to shame!  However John Chen came out on top with 73 digits memorised and written (bearing in mind this is in one lesson).

We asked John if he would like to have another chance to see if he could achieve more.  So after a spot of lunch he came back to class and here’s what happened…

As a bit of fun in class this morning to mark Pi Day, students were asked to see how far they could memorise and write Pi to. John Chen of College 1 managed to memorise to 73 places in class, so we asked if he fancied attempting again at lunchtime so we could film. He managed to get to 100 and even wrote in the shape of Pi!! Just amazing 👌🏻👌🏻👌🏻💯 #PiDay #amazingmaths #funmaths

WOW!

Just so amazing to watch! Our students really are an inspiration to us all.

FACT OR FICTION? Former student Chris Hall memorised Pi to 1000 digits in his time at Bootham

FACT OR FICTION? The current Guinness World Record is held by Lu Chao of China, who, in 2005, recited 67,890 digits of Pi.
