Celebrate Pi Day and Maths Day

Pi Day

Pi Day is an annual celebration commemorating the mathematical constant π (pi). It is observed March 14 since 3, 1, and 4 are the three most significant digits of π in the decimal form.

Daniel Tammet, a high-functioning autistic savant, held the European record for reciting pi from memory to 22,514 digits in five hours and nine minutes until 2015 when Rick de Jong of the Netherlands recited pi to 22,612 digits in five hours and 34 minutes. His record was then broken by Rajveer Meena of India, who recited 70,000 digits in 2015 blindfolded. It took over nine hours. That remains the world record to date.

. Here’s how you can memorize the first 100 digits of Pi:

It is one of the world’s largest global educational events aimed at lifting numeracy standards in a fun and meaningful way. If you wish to celebrate with fun maths events, take a look at this video from the World Maths Day Website:

Up to 4 million students world-wide participate in the online competition.
