Celebrating Pi Day 2025

Pi Day, celebrated annually on 14 March, is a tribute to the mathematical constant π (pi), which represents the ratio of a circle's circumference to its diameter. This date was chosen because the first three digits of pi are 3, 1, and 4, matching the month and day in the UK date format (14/3).

The tradition began in 1988 at the Exploratorium in San Francisco, where physicist Larry Shaw organised the first celebration. Since then, Pi Day has gained international recognition, with UNESCO designating it as the International Day of Mathematics in 2019.

Pi Day is not just about mathematics; it also, significantly, coincides with Albert Einstein's birthday.

Schools and institutions around the world celebrate Pi Day in creative ways. Pupils at Churcher's marked the occasion with a Pi art competition, where pupils visually represented the digits in pi or the Greek letter pi itself. Additionally, pupils participated in a digit memorisation challenge, showcasing their impressive memory skills. Special mentions go to Will, who successfully recalled 50 digits, and Finley, who achieved a remarkable feat by memorising 470 digits of pi.

The college's catering team also joined in the festivities by offering apple pie at lunch. Who knew maths could be so delicious?
