I must disagree. I suppose it's good for Warren to have an
apologist, but you are simply not getting the facts right. Warren
seems to be unable to deal with constructive criticism.
What you characterize as attacks by "arrogant naysayers" (and as
professional engineers looking down on amateur engineers) has, to my
reading, been a fair attempt by other listmembers to understand
Warren's TPLL implementation so that they can try to ascertain to
what degree it is likely to provide useful results over a broader
range of conditions than those that have been publicly
demonstrated. As we have asked for more details so we can try to do
this, Warren has responded in every case -- every case -- with vague
allusions to details of his implementation and testing he has done,
childish accusations that nobody understands anything and we all must
think he can't add two and two, followed by more and more outlandish
claims about what his device does (for just one example, "the simple
analog TPLL method holds the Phase difference [between the reference
and test oscillators] to zero (with-in 1 femtosecond)" -- Wed, 9 Jun
2010 21:05:57 -0700), which (i) cannot be true and (ii) appear to
demonstrate that Warren not only has not tested at least some of the
things that he is claiming, but seems not to understand much of the
basic subject matter. Warren has had more than ample opportunity to
answer any criticism by saying calmly that he did "a" (with a decent
explanation of what "a" is) and got "x" result, and similarly with
"b" and "y," "c" and "z," etc., but he has not once done so. One
might reasonably conclude after all of the smokescreens and refusals
that he has not, in fact, done any of the things to which he has
vaguely alluded.
I know you have said more than once that we should just ignore "the
femtosecond thing," but why? (Not that anything turns on this one
claim anyway -- there are plenty of others like it.) You yourself
called it into question (Thu, 10 Jun 2010 17:05:26 +1200). It is a
claim Warren made, and very specifically -- not that a femtosecond is
the resolution of the test method stated in units of time (which
others have advanced to try to explain what he meant), but that his
PLL locks two 10 MHz oscillators to within one femtosecond of each
other and that he has verified this in several ways. If Warren
claims this thing (and numerous others that can easily be found in
the voluminous record) that must be mistaken (or worse), what else
that he has claimed can we trust? When you read the posts and make
the inferences that Warren's statements invite (in many cases,
seemingly inescapably), it appears that the only trustworthy
information we have about the operation of Warren's TPLL is what John
published -- which indicates that the method has promise -- perhaps
even considerable promise -- but is far from the proof Warren seems
to think it is that his device fulfills all of his claims or has been
characterized to the point that others can predict under what
conditions they can rely on it.
So, please, don't make Warren out as the poor, well-meaning basement
inventor being bashed by the "professionals." His childish tantrums,
insults, and outlandish claims are his and his alone. Even if we
assume for the sake of argument that he was hard done by (which I do
not believe is true), that would not excuse his responses. It would
have been one thing to say, "Hey, I put this together and it seems to
work pretty well" and leave it at that, but that is not what Warren did.
Best regards,
Charles
