I dunno that I'd call it three orders - it's close at about 830x - but it's definitely not even close to being one order either.
- colechristensen 6y agoI think it’s an unnecessary nitpick. One statement is general and the other is a specific, extreme example. “usually 10x, sometimes 1000x”, that sort of thing
- m463 6y agoI think it is three orders of magnitude. "An order-of-magnitude difference between two values is a factor of 10. For example, the mass of the planet Saturn is 95 times that of Earth, so Saturn is two orders of magnitude more massive than Earth." https://en.wikipedia.org/wiki/Order_of_magnitude https://en.wikipedia.org/wiki/Order_of_magnitude
- zimpenfish 6y ago> "More precisely, the order of magnitude of a number can be defined in terms of the common logarithm, usually as the integer part of the logarithm, obtained by truncation." $ bc -l l(835)/l(10) 2.92168647548360208478 That would make it 2 orders of magnitude by that method. Happy to accept that it's 3 orders of magnitude by the N=a*10^b method though. Either way, it's definitely not one.
- m463 6y agoI think the whole point of orders of magnitude is to be a back-of-the-napkin estimation of what's what. "a new car is an order of magnitude difference in price compared to a used car" is appropriate even if a new car is 40k and a used car is 5k Electric cars have two orders of magnitude less energy storage than gasoline cars, but newer ones are only one order of magnitude.
- dragonwriter 6y agoSince orders of magnitude are multiplicative, rounded to the nearest whole order of magnitude ~300× to ~3000× is three orders of magnitude.
