what is your POV about Newtonian mechanics?

[sethman]

what is your point of view about Newtonian mechanics? and what about quantum mechanics?

is Quantum mechanics override the Newtonian mechanics? isn't newtonia mechanics necessary for quantum mechanics to exist and for the future?

The transition away from Newtonian mechanics (NM) into General Relativity and Quantum Mechanics (GR and QM) is a lesson in relativity. The descriptions provided by NM are only useful relative to a certain scale of measurement. 

When you go to the very big or the very small, the models that you are able to use to describe the world changes, and it happens that NM is very anthropocentric (it only works within very human conditions; energy levels, speeds, distances etc.).

The nature of things like energy, motion, time, particles, waves; all of that changes depending on your level of analysis. In that sense, QM and GR don't necessarily override NM, because there are cases where NM is sufficient to solve problems (like some basic engineering calculations).

There's not much here to work off, write something more to explain what you already know, what you currently think. Unless people know what you're really after in answering this question, as well as your level of knowledge and seeing your thought process, it's less likely for this question to go somewhere

 

Newtonian mechanics isn't defunct, newton's laws still work all the way from tiny particles (in the right context) to massive planets in orbit {relativity is newtonian paradigm + a few modifications, some added terms. Not trying to insult relativity though, relativity is very cool, it changes some intuitions about space and time. But just commenting on a bigger picture, whilst also telling you how vital Newtonian Mechanics is. } 

If science is about modelling and predicting behaviour of the outside world, newton's laws still work for that.

Newton's laws of motion are an approximation of the general relativity. You can derive Newton's laws starting from general relativity assuming bounded parameters and approximation. https://dev.relativitycalculator.com/password_protected_files/newton_laws_from_general_relativity.shtml
