Mysterious Pi and the Size of the Universe
As today is PI day, we thought you too might find this fascinating.
The mystery of PI is extremely fascinating in that its value appears to be infinite just as our Universe seems to be. Could this indeed be a numerical representation of the state/size of our universe, freaky!
via Numberphile YouTube:
Pi is famously calculated to trillions of digits – but Dr James Grime says 39 is probably enough. All our Pi videos: http://bit.ly/W4oDN1
An extra note from Dr Grime: “Since pi39 ends in 0, you may think we could use pi38 instead – which has even fewer digits. Unfortunately, the rounding errors of pi38 are ten times larger than the rounding errors of pi39 – more than a hyrdogen atom. So that extra decimal place makes a difference, even if it’s 0.”
