Happy Pi Day!
Today is such a strange “holiday." It's a day to commemorate the mysterious number known as pi. 3.14, except it's not 3.14. It's 3.14159265, but actually, it's more, much more. It's an endless number, an infinite string of digits, never ending, never repeating, never falling into a pattern. The number of calculated digits of pi currently stands at 202.11229 trillion. That's an incomprehensible number of digits, yet, it's no closer to the full truth of the number than 3.14.
Pi is not only mysterious for its infinite nature, it is also an incredibly important number in our world. It is found in, and plays an integral role in, geometry, trigonometry, calculus, physics, astronomy, statistics, and biology. It's part of things like heartbeats, circadian rhythm, breathing cycles, and even the stripes on zebras. It even helps us understand DNA.
