Yes, I am late again… but no number can claim more fame than pi. But why, exactly?

Defined as the ratio of the circumference of a circle to its diameter, pi, or in symbol form, π,seems a simple enough concept. But it turns out to be an “irrational number,” meaning its exact value is inherently unknowable. Computer scientists have calculated billions of digits of pi, starting with 3.14159265358979323…, but because no recognizable pattern emerges in the succession of its digits, we could continue calculating the next digit, and the next, and the next, for millennia, and we’d still have no idea which digit might emerge next. The digits of pi continue their senseless procession all the way to infinity.

Let’s not forget that Pi shares a B-day with Mr. Einstein and a final departure with Mr. Hawking.

Happy belated Pi Day!
