Wolfram MathWorld: Pi Digits The first thirty million digits of pi are almost uniformly distributed. That is, 1 occurs with the same frequency as 2, 3, 4, etc. That's consistent with randomness, but hardly evidence of it.
Ludolph Van Ceulen’s Headstone This Dutch mathematician devoted his life to calculating pi. By the time of his death, in 1610, he had calculated the first 35 digits, a feat that by modern standards is a pathetic waste of a life, but for the time was an amazing accomplishment. He had the numbers inscribed on his headstone.
