Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.
Albert Einstein (b. 14 march 1879 - 1955) physicist, philosopher, peace activist
speaking of infinity today is pi day, pi starts out 3.14 and represents the ratio of a circle's circumference to its diameter. aided by computers mathematicians have calculated up to the 5 trillionth digit of pi, the number itself is irrational, meaning its decimal representation will repeat infinitely.
just to make sure your information is correct remember pi day is not the same as pie day
