Pi and the size of the Universe – Numberphile

Our Pi Playlist (more videos):
Pi is famously calculated to trillions of digits – but Dr James Grime says 39 is probably enough.

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.”
