Time dilation of everyday life is so small that it's not detectable to all but atomic clocks, over the course of your entire life. So the differences between 10 miles is so negligible it doesn't even exist as an issue.
- komali2 10y agoWhy would it be relevant, then, for a programmer to know that?
- Bartweiss 10y agoMostly it's not. Charitably, someone writing software for e.g. a particle physics experiment might actually need to account for altitude to produce accurate results. Of course, that's the sort of domain-specific demand that might not belong in a general-use list. People writing sound engineering software have to worry about all kinds of subtleties with sample rates and harmonics, but I wouldn't put that in a guide to basic data I/O - I might not even put it in a basic analog-to-digital guide.
- AckSyn 10y agoThe writer may have been exaggerating their point.
- manarth 10y agoA programmer working on something like the OPERA neutrino experiment would need to account for those factors [1]. GPS devices also have to account for relativity [2], so programmers working on those also have to factor that into the logic.

- ska 10y agoIt doesn't practically exist as a problem for things (like people) for whom a meaningful time scale is around a second, and a lifetime 100yrs. If you are operating on very small time scales, or if you're going to be around a long time, it can matter a lot.
- Piskvorrr 10y agoGood luck with your GPS navigation then. "You are here. (Give or take 10 miles, no biggie, eh?)" There is a surprising number of applications in your everyday life for which Newtonian physics are not precise enough.
