ELI5: How can Newtonian physics be technically "wrong" , but still mathematically explain many natural processes?
gpt
It is less wrong, and more of an incomplete approximation.

For example, you have a farm in Kansas that is 5 miles by 5 miles.  You have exactly 25 square miles, right?  Area = side * side, after all.

That would be wrong.  You have slightly more than 25 square miles, because the earth is roughly a sphere.  That doesn't mean the formula for area is wrong, it just doesn't take into account spherical surfaces.  It is also very accurate over small distances.

Newtonian physics is the same way.  It isn't wrong, it just doesn't take relativity into account.  And for speeds that aren't a significant fraction of the speed of light, it is quite accurate.
