At some point I learnt pi as 3.1415926535897 (I have had a couple of wines and I am not going to check this) | |

Does anyone know what the highest precision actually used in any application on Earth might be? For my uses, 3.1415926 is as close as I use, and that's probably way beyond what's really needed.
I do understand that the 62.8 trillion digits was done for bragging rights. To show that they could, basically. | |

I also vaguely remember that about 10 digits of pi is fairly accurate - within a couple of centimetres of calculating the circumference of the universe. | |

39 is enough to compute it to the width of an atom.
Which, considering that spacetime is not uniformly Euclidean, is not exactly a useful or reliable calculation if you need that kind of precision and could provide a measurement of radius that is remotely as precise. (Now I'm having flashbacks to HS science and significant figures)

I did check this after posting - it was correct. It is kind of like peaking into the box with the cat without collapsing the wavefunction. | |

For me, studying (or more precisely not studying) physics at university was about discovering the most neat and finished part of physics - classical mechanics with Lagrangians and Hamiltonians. The opposite of quantum where care needs to be taken in studying it for risk of changing what is being learnt. I didn't take the risk :) | |

I think I meant peeking.
Just staying ahead of quantum - or behind.
Keeping my distance from how much I weigh when I know my electricity bill.
Or what time it is if I remember I have left my phone in the other room. | |
