No, they're also wrong in a typical human context.

Most people have a phone with GPS these days. GPS would flat-out fail to work entirely without correcting for time dilation effects in the satellites. Newton had no concept of time dilation (nor should he have, given his context).




Interesting description of “relativistic” effects in the GPS system. http://www.tuks.nl/pdf/Reference_Material/Ronald_Hatch/Hatch....


They are wrong in _that one example_. For most other day to day scenarios, Newton's laws are plenty accurate.

I disagree with the poster about that saying. I think it's a fantastic saying.


I'm not sure I follow your argument, perhaps you can help me understand. If you're saying that Newtonian Gravity breakdown in a specific case but are fairly accurate in other cases does that mean they're still universally correct?


I'm saying that for most everyday situations, Newton's equations provide sufficient accuracy for people to achieve their goals. However, in the case of GPS, the system wouldn't work reliably if it was only using Newton's equations.

Einstein's theory of gravity is much more robust and is highly accurate across a far wider domain. It can be used to implement a reliable GPS system.
