I do not substitute arguments by distrust.

I don't have any idea who Scotty is. Ohm lectured Seebeck in a similar manner. Seebeck proved correct more that a hundred years later. I say: Do not consider your careless application of the uncertainty principle a law of physics.

Simply by providing delta f as small as you like since there is no arbitrary time window to chose. Delta t is given by the sample rate of the input.

What did you read?

Those who are aware of not knowing all might be more prudent.

What about me, I do not have command over time. Perhaps, you feel like god. At least you are a believer no matter in what.
> The conclusion > that the direction of time makes any difference here for the result, > IMHO, is wrong.
I consider your opinion not humble but perhaps a bit stupid in that case. I feel myself in the same position as my ears. They cannot analyse future data. I am not speaking of fictitious theoretical time and its manipulation at will applied on already recorded data. You are correct if you restrict your thinking to Laplace's deterministic position. You are more than a century too late. Eckard
This all sounds very interesting.  Do you have a journal paper, 
conference paper or patent describing the approach?  I'd like to read 
more about it.  Usenet is not the best or most reliable place for this 
kind of information.

Many thanks,

Paul
If you read German, you might look into the CD of DAGA'03. Do not expect 
too much, since my two papers in it were written more than a year ago.

What about Usenet, I appreciate the possibility to get diverse valuable 
critical replies. Initially, I did not exclude being wrong at least in 
part. Meanwhile, I feel largely correct.

However, I am sure: I would rather have the chance to win in a lottery 
than to get immediately accepted with all my ideas and findings by a 
pair of cautious anonymous referees before I carefully checked every of 
my arguments and anticipated any stupid suspicion against it.

Some marginal mathematical questions are highly controversial.
While I could ignore this, I am not satisfied until I found out the 
truth. In particular, Buridan's donkey and Cantor's paradise are not yet 
completely overcome by Robinson's non-standard analysis.

I am suggesting a unilateral notion of Dirac-delta impulse for IR+.

It took me 18 months of fierce discussion until Hendrik van Hees 
apologized for wrongly blaming me wrong. He is a quantum physicist, and 
the standard model is based on assumed symmetries in complex plane. I do 
not exclude that there is an alternative interpretation.

While nobody found an error in my reasoning so far, I got aware of an 
elusive symmetry in a PRL paper.

There is a long standing quarrel between Peter Cariani and Christian 
K�rnbach. My idea of joint autocorrelation would completely agree with 
the experimental work of both, and it also tallies to work by Lutz 
Wiegrebe. Unfortunately Christian prefers to reject my attempt to 
reconcile them without factual dispute just because he fears damage to 
his reputation based on a JASA paper. Such things happen, he wrote.

Once more again...whre can I find any papers describing this approache???

In other words, I am still looking for serious description with more
mathematics and significantly less intricately understandable sentences.

Maybe, I found out why both the natural spectrogram and function of cochlea are seemingly not bound to the uncertainty principle. Frequency of the response chirps up. In other words, while one gets a very early response, the initial value of frequency deviates from the stationary one. It takes about the theoretically necessary time until frequency approaches the stationary value. Perhaps, this phenomenon is similar to the superluminal propagation found by Nimtz. Eckard

Superluminal propagation of what? Surely not of energy or information! Superluminal phase velocity is unremarkable. For one, it happens in every electromagnetic waveguide.

Of course. Nonetheless, superluminal propagation of evanescent modes in a waveguide caused a lot of confusion. Faster than theoretically possible frequency analysis within the inner ear and in particular with the natural spectrogram caused a lot of avoidable distrust. Eckard

When a phenomenon is faster (shorter, longer, stronger, ...) than theoretically possible, it's time to revise the theory. When aerodynamic theory "proved" that bumblebees can't fly, aerodynamicists knew that a new and better was called for. "Not theoretically possible" is one kind of reductio ad absurdam.

...or it's time to double check the numbers... :-)

I agree. However, in Eckards case, we have yet to observe the phenomenon! ;-) --smb

This was the claim of Nimtz. However, he just misinterpreted the preconditions and assumptions of his strange measurement. Before demanding a revision of theory one should check whether or not it is correctly applied. The same confusion was with causality. If I recall correctly, someone famous called it a relic of bygone time. Laws of nature are tricky sometimes. Eckard
