There are many days celebrating maths (aren't all days maths days?), but we in Oxford Mathematics have a soft spot for today, Pi Day, for the complex mathematical reason that Pi is the name of our cafe. So, to celebrate, we baked. https://t.co/9TYRrVeERN

3rd Year Maths students attended a Pie maths quiz today and Anton, Nikola, Sarah and Cliodhna came joint third. Pi Day is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant figures of π. 👋#maths #STEM https://t.co/6QRneH68ED

The maths team are enjoying celebrating pi day today. Did you know Welsh mathematician, William Jones, was the first to use the green letter to represent pi? #mathematics #piDay2023 https://t.co/K3XHmGnOrs
