Brercrow: Wizofoz thinks that wind is the same as no wind because all inertial frames of reference (IFR) are equally valid and he can measure a velocity relative to any IFR
Discuss
[To be picky. To transform a velocity measure in one IFR to that which would be measured in another IFR you need to factor in the relative velocities of the two IFRs.]
If Wizofoz is wrong it looks like Einstein's theory of relativity must be as well.

Measurements in one inertial frame can be converted to measurements in another by a simple transformation (the Galilean transformation in Newtonian physics and
the Lorentz transformation in special relativity).
Without exceptional evidence to the contrary I'll side with Wizofoz on this one (but see PS).

I'd been wondering if one way of making the discussions more productive would be to try and devise a "critical experiment" which would provide real concrete evidence
rather than opinions and potentially flawed calculations.
I'm thinking of something that could be measured with a GPS receiver on a light plane. You'd probably also need a ground-based windsock and anemometer mounted
sufficiently high to be out of near-ground wind-shear and turbulence.

In the sciences, an experimentum crucis (English: crucial experiment or critical experiment) is an experiment capable of decisively determining whether or not a
particular hypothesis or theory is superior to all other hypotheses or theories whose acceptance is currently widespread in the scientific community.
