- TL;DR Summary
- Reference frame vs coordinate system (or coordinate chart) in the context of SR and GR

Hello,

here on PF I've seen many threads about the concepts of 'reference frame' and 'coordinate system'.

In the context of SR my 'envision' about the concept of 'frame of reference' is basically the 'rods & clocks latticework' as introduced in the book

As far as I can tell this way we have actually defined: (1) a frame of reference -- the latticework -- and (2) a coordinate system for it (aka a coordinate chart).

Next step is to take in account the conditions for which (1) + (2) actually define an 'inertial frame'.

Do you think it could be a reasonable way to introduce both the concepts of frame of reference and coordinate system (coordinate chart) for SR flat spacetime ? Thanks.

*Spacetime physics*(Taylor, Wheeler). Clocks attached on rods run at a whatsoever rate and employing a whatsoever procedure we can assign three numbers to each rod in order to identify their spatial position in the 'grid'. The only requirement for this 'assignment procedure' is to be smooth.As far as I can tell this way we have actually defined: (1) a frame of reference -- the latticework -- and (2) a coordinate system for it (aka a coordinate chart).
