SR Foundations: Parallax Methods? - Reference Request

Click For Summary
SUMMARY

The discussion centers on the foundations of Special Relativity (SR) and critiques the traditional use of "rigid rods" and "rigid scales" for establishing inertial frames. The author recalls a paper proposing an alternative foundation using parallax methods, which involves inferring coordinates for a remote event through two angles and a local baseline scale. Despite attempts to locate this paper, the author has been unsuccessful. The conversation highlights a need for modern approaches to SR foundations, particularly those that avoid outdated methodologies.

PREREQUISITES
  • Understanding of Special Relativity principles
  • Familiarity with the concept of inertial frames
  • Knowledge of parallax methods in physics
  • Basic grasp of light signal propagation and Einstein's theory of invariance
NEXT STEPS
  • Research the use of parallax methods in modern physics
  • Explore alternative foundations of Special Relativity beyond traditional methods
  • Investigate the implications of light signal propagation on inertial frames
  • Look for academic papers discussing non-standard approaches to SR foundations
USEFUL FOR

Physicists, researchers in relativity, and students seeking to understand alternative methodologies in Special Relativity foundations.

Standard treatments (e.g., Rindler) of the foundations of Special Relativity invoke use of a "rigid rod" or "rigid scale" by an observer to construct his inertial frame -- by (somewhat fictionally) transporting the rod (and also cloning copies of a standard clock at every point in the frame). Alternatively, there's also appeals to the radar method of sending and receiving light signals to establish the frame. ISTM, use of such dubious motivations becomes an ever-increasing embarrassment in the modern era.

I vaguely recall a paper that proposed an alternate foundation based on an observer using parallax methods. I.e., inferring coordinates for a remote event in terms of two angles and
a local baseline scale (and of course the Einsteinian invariance of light velocity). I've tried various searches to re-find this work, but failed.

So I'm wondering whether such a parallax method for SR foundations rings a bell with anyone here? Does anyone know references, or perhaps an alternate name for this approach?

TIA.

@strangerep did you have any more insight on this topic?
No, I never found that original paper and eventually moved on to other topics.
