I hate to see Cecil and others criticizing Tom's (W8JI) measurements,
although I've certainly learned to expect this sort of response whenever
his theory is shown to be lacking. Tom does a careful job of making
measurements and he has good equipment. Most importantly, he's honest.
If someone finds an error with this measurement methodology or results,
he'll be the first one to correct it. But "finding an error" doesn't
mean just saying that his measurements fail to support a wild theory. It
means making careful measurements with good equipment and methodology
which give different results. I'm sure we'll never see this from Cecil.

Like I did some time ago, Tom has taken the time and trouble to make
measurements which simply confirm what established theory tell us. Then
Cecil and others respond by stating they're in error but haven't
presented any evidence to the contrary. (Sorry, hot air doesn't count as
evidence.) Any readers not astute enough to see the problem here
probably feel at home with astrology, homeopathy, and other alternative
disciplines that elicit belief without evidence.

That is his "obvious" explanation. He should remove that from his

W8JI made a gross error in his measurement and
then tried to rationalize the impossible result.



Cecil:

How would you have like to be working at NASA, with this group; And,
you were the one responsible for not coverting kilometers to miles and
SMACKING that spacecraft we lost into Mars? ;-)



It wasn't km and miles, it was pounds and newtons AND
the error was that Lockheed Martin supplied the thrust data in pounds,
unlike the contractual requirement to supply it in Newtons (which is
what we at JPL have used for decades). The error wasn't caught because
the absolute magnitude of the force is very small, so the differences
from predict to observation were on the order of the measurement
uncertainty. (We're talking measuring the velocity to mm/sec and range
to mm, when its at Mars.)
I'd venture that anyone would find measuring distances to 1 part in 1E12
challenging...





Crud, I've volunteered on serving on those soup-lines, would hate to
have seen ya' there. chuckle
