"Pi Day: Pies, Pizza Deals, and Surprising Facts to Celebrate Math and Science"
Math enthusiasts celebrate Pi Day on March 14, honoring the essential mathematical constant π, which is the ratio of a circle's circumference to its diameter. Pi has a rich history, with records for memorization, a unique "Pilish" language, and exponential growth in decimal places calculated. While NASA only uses 16 digits of pi for most calculations, researchers have calculated pi to over 62.8 trillion decimal places. Despite its long history, there are still unanswered questions about pi, including whether it is a "normal" number.
