I Relativity Theory: General & Special Contexts

[MoradLemans]

I want to know in which context should i take relativity with both general and special .

I'm sorry, I don't understand your question, and I suspect nobody else will, either. Can you explain it further?

I certainly don't.

What do you mean by "context"?

 

[MoradLemans]

Is it classified in Quantum Mechanics or Classical Mechanics ?

 

[ZapperZ]

Is it classified in Quantum Mechanics or Classical Mechanics ?

Why does this matter so much?

BTW, it is not Quantum Mechanics.

Zz.

Relativity is its own field. It is neither classical mechanics nor quantum mechanics.

 

[MoradLemans]

Relativity is its own field. It is neither classical mechanics nor quantum mechanics.

Why relativity is an independant field ?

 

[mfb]

Because it is neither classical mechanics nor quantum mechanics...

Hm. This post seems to have been edited such that it appears to be a response to mfg, which is was not. I'm going to delete the content to avoid confusion.

i think you wish to know whether 'quantum' ideas can be incorporated in relativity whether its STR or GTR- i think till the quantization of 'graviton'
or discovery of a particle which can mediate /connect the action of 'gravity field' or say 'quantization of gravitation' does not come up -it can not be said to be a part of quantum physics.
so its a classical theory encompassing the four dimensional space-time.-where time has been given a special status of coordinates and forces are derived from the curvature of space-time fabric.

 

[phinds]

so its a classical theory ...

but you need to be clear that you are not telling him that it is classical mechanics.

How are you defining "Classical Mechanics"? Some people define it as "everything that isn't Quantum Mechanics", in which case SR and GR would both be "Classical". But that's not a very informative definition.

The more common definition, which is the one the other posters are using, defines "Classical Mechanics" to mean Newtonian mechanics: Newton's three laws of motion and his law of gravity. SR and GR are not "Classical Mechanics" by this definition; they are "Relativistic Mechanics", which is a separate field of its own.

well sorry -i should have said that
its a classical theory but not 'classical mechanics' as its a development based on space-time description of events so its treated outside mechanics- but relativistic dynamics is 'classical'..

Thank you very much !

This I don't understand either. Relativity is an unfortunate name for "space-time model". So it's comprehensive for all of physics, classical and quantum. The special theory is an approximation to the general in neglecting gravity.
