The Infinite World of Pi Day
Pi Day, celebrated on March 14th each year, is an annual celebration of the mathematical constant Pi, approximately equal to 3.14, which is why the day is 3/14. This event, established by physicist Larry Shaw in 1988 at the San Francisco Exploratorium, has since become a global event. On this day, math enthusiasts around the world celebrate in unique ways, from eating pies to throwing them! But why all this fuss over Pi? Well, Pi is an irrational number, meaning it's a never-ending, non-repeating decimal. In fact, Pi has been computed to over one trillion digits beyond its decimal point. However, only 39 digits are needed to accurately calculate the spherical volume of our entire universe! Now, isn't that something to celebrate?
