I was proud of the fact that I knew Pi to 10 digits. Obviously I am out of my league amongst the luminaries on this list. I should be sent back to the farm team. This reminds me of a sci fi series (can't remember which one) I saw many many years ago about how a crew of a spaceship overcame a rogue supercomputer by asking it to calculate the last digit in Pi. It fried the whole system.
