Even though I am a fan of numbers in general, my favorite number is π. π is the famous irrational constant used in measuring the area and circumference in circles, plays an important role in trigonometry, and the Gamma of 1/2 is the square root of π. Every March 14 is designated π Day, celebrated around the world, particularly in mathematical circles, schools, and universities. It also happens to be the birthday of Albert Einstein, Billy Crystal, Les Brown, Quincy Jones, and yours truly (Eddie - the writer on this blog).
Going by memory, the first 15 digits of π is 3.14159 26535 89793.
So, what is your favorite number?
