Did you know that today is Pi Day? This is celebrated on March 14th 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.
Pi has been calculated to over one trillion digits beyond its decimal point. It will continue infinitely without repetition or pattern. Pi’s infinite nature makes it a fun challenge to memorize - I know that we have some brilliant mathematicians at Great Gaddesden School so how many digits can you memorize?! Remember there are over one trillion to aim for!
I think that some mathematician had fun deciding that Pi day should be on March 14th (3/14)!

ReplyDeleteCallum: 3.1415926
Ollie: 3.14159265
Josh: 3.14159265359 (This is as many decimal places as we have looked at today!)
Charlie: 3.14
Oscar: 3.14159
Shyla: 3.14159265359 (Another champion!)
A good start!
That's brilliant! I thought you might like to read this from the Guiness Book of Records:
DeleteThe record for memorising Pi was achieved by Chao Lu (China) who recited Pi from memory to 67,890 places.
Chao Lu, a chemistry student, attempted the record after practising for 4 years. The attempt lasted 24 hrs 4 min and was recorded on 26 video tapes.
