Pi Day!

Pi, Greek letter π, represents the relationship between a circle’s diameter (its width) and its circumference (the distance around the circle):

Pi Day is celebrated on March 14th (3/14 in American notation).  Often rounded to 3.14, its decimal digits continue infinitely and do not repeat or settle into any pattern.

With the use of computers, Pi has been calculated to over 1 trillion digits past the decimal point.  Many formulae from Mathematics, Science, and Engineering involve Pi, which makes it one of the most important mathematical constants.

Memorising the digits of Pi has become a competitive affair!  The current record is held by Kumar Suresh Sharma from India, who recited 70,030 digits on 21st October 2015.  It took him 17 hours and 14 minutes!

To celebrate Pi Day at Coombe Dean, we held our own memory competition.  The winner was  Molly B, with an impressive 60 digits of pi recited from memory.   The top 3 students, who each received a prize and certificate for their achievement, are:       

  • Molly B – Year 8 – 60 digits
  • Lara T-S  – Year 7 – 57 digits
  • Poppy E – Year 8 – 54 digits     

We also held a baking contest, where students could enter by bringing in a cake or pie, with a Pi theme.  There were a huge number of entries this year and the standard was very high, but we managed to pick 3 winners.  They each received a prize and certificate for their fabulous Pi creations:

  • Jamie S – Year 8
  • Joseph J – Year 7
  • Louise W – Year 7

Well done to all students who took part in Pi Day!
