"I've used cosmic ray muons as an example in support of special
relativity... but every time I mention it, I fear the logical question
"Oh but how was the muon lifetime measured at rest"... it hasn't come
up yet... but surely one day it will. So how was the muon lifetime
measured at rest? Or more accurately who/when/where first measured the
muon lifetime at rest. Although I do not doubt that SR is valid (for
now), I want to know if people just measured muon decay rates at
different velocities and extrapolated (using SR) the lifetime at
rest... since that would kind of make for a circular argument when it
comes to SR validity."
Tom Roberts, the Albert Einstein of our generation (Stephen Hawking is
no longer the Albert Einstein of our generation) immediately answered:
" http://pdg.lbl.gov/ They surely have numerous references giving
measurements of muon lifetimes (and, of course, other particles and
other properties). While I don't have references, I know there are a
number of muon beamlines in the world in which muons are routinely
brought to rest, and a measurement of their lifetime would naturally
be part of the analysis of other things of interest (e.g. muon
catalyzed fusion, which requires stopped muons). Tom Roberts

Obviously the Albert Einstein of our generation does not want to go
into much detail because he does not have references so here is a
typical measurement of the muon lifetime at rest:
http://web.mit.edu/c_hill/www/muons_paper.pdf "In this experiment, we
measure two of the basic properties of the muon, namely, its mean
lifetime and mass in its rest frame. We measure the decay curve of
cosmic-ray muons that have come to rest in a plastic scintillator by
looking for electrons produced in their decay."
Now Roberts you do have references so there is only one thing you
should do (in your capacity of Albert Einstein of our generation). You
should PROVE that reducing the speed of the muon to zero in the
plastic scintillator does not make muon's life extremely difficult,
with a premature death as a consequence. Your PROOF would be important
wouldn't it Roberts.
Don't forget two more explanations you are to give:

either does not understand, or intentionally misunderstands.
