This article says that NASA uses 15 digits after the decimal point, which I’m counting as 16 in total, since that’s how we count significant digits in scientific notation. If you round pi to 3, that’s one significant digit, and if you round it to 1, that’s zero digits.
I know that 22/7 is an extremely good approximation for pi, since it’s written with 3 digits, but is accurate to almost 4 digits. Another good one is √10, which is accurate to a little over 2 digits.
I’ve heard that ‘field engineers’ used to use these approximations to save time when doing math by hand. But what field, exactly? Can anyone give examples of fields that use fewer than 16 digits? In the spirit of something like xkcd: Purity, could you rank different sciences by how many digits of pi they require?
If it’s anything like the little island off it’s east coast it will be steak and black pepper of a chicken korma pie
Steak and black pepper pie, now that’s what I’m talking about!
Peppersteak and Tomato ftw.
Chilli beef and cheese from a servo or gtfo.
I often find chilli beef on the dry side, I guess that it would mean that that pie may need only 5 digits and not the full 10 of a juicy steak pie
With cheese inside its a sloppy mess and often requires the full 10. Though tbh I haven’t lived in Australia for 10 years or eaten meat in 20, so I wouldn’t listen to anything I have to say about pies.
Fraser Island? Or Tasmania?
The ones slightly larger that tasmania…
Sacrilege!
Firstly 1, 500 km away is not coastal (if it was then the UK is an island off the coast of Iceland).
Secondly if anyone is off anyone else’s coast it’s the west island which is off our coast, not the other way round.
true enough
You’re right about the pies but.
