Pi Day Celebrates the Mathematical Constant with Pies and Contests

March 14 marks the annual celebration of pi, a key number in mathematics and science, with activities ranging from pie baking to memorization challenges.

Pi Day is celebrated annually on March 14, honoring the mathematical constant pi, represented by the first three digits 3.14.
The day is marked by various activities, including pie eating and baking, as well as pi memorization contests.
Pi is an irrational number, essential for calculating the area and volume of circular and spherical shapes, and has been known to humanity for thousands of years.
NASA utilizes only the first 15 decimal places of pi for most of its calculations, demonstrating the number's practical application in space exploration.
The record for memorizing digits of pi is held by Rajveer Meena, who recited 70,000 decimal places in 2015.
