The world celebrates International Day of Mathematics and Pi Day
The world celebrates International Day of Mathematics and Pi Day
This date, written as 3/14, is famous as Pi Day because it mirrors the first three digits of the constant pi (π).
Created in 1988 by physicist Larry Shaw, the celebration originally involved eating fruit pies and celebrating science.
Interestingly, this date also marks the birthday of Albert Einstein.
In 2019, UNESCO expanded this tradition by establishing the International Day of Mathematics (IDM).
While the fun of eating pies continues, the goal of IDM is to highlight how math is the universal language behind modern technology, medicine, and global problem-solving.
By making mathematics accessible and inclusive, the global community hopes to encourage more people—especially those historically underrepresented in STEM—to see math as a vital tool for change.
From classrooms to research centers, this day reminds us that mathematics is everywhere.
So, on your next Pi Day, enjoy a slice of pie while reflecting on the infinite ways mathematics improves our daily lives.
