Just a final bit of spice then: physicists do *not* hold a realist's view of reality, that is, a physicist will tell you physics deals with correlations of perceived sensory data, a phenomenological approach. This is not really true of all or even most physicists. Many hold the view that there is an objective reality, that may be describable by many different models. Some hold the view that there is no objective reality. I am in the same camp as Einstein, that there is an objective reality. Because I know Goedal, I can accept that this may be true, even without proof. The evidence suggests that there is a real reality, despite some claims to the contrary my writers of popular physics Bantam paperbacks. A main issue with popular expressed physics is that many metaphysical ideas are presented as being a consequence of the physics known to work, when in fact, the physics don't care about someone's particular interpretation. For example, collapse of the wave function, particles in two places at once, or many universes, are all waffle ideas that are not required in the slightest in quantum Mechanics. They are redundant add-ons. QM works pefectly well without these daft ideas. Funny that you should mention Quantum Physics - it's precisely the findings in this field that tell us, Idealism is the 'best fit'. Maybe add some Feymann books to the list there.. No it doesn't. That's why I mentioned it. You must have missed my bit about "popular descriptions of physics". There is *nothing* in physics whosoever that indicates Idealism.

Some say that no matter how fast the FB gets back to the input, there is a delay, and the signal isn't in "real time", and the signal is somehow spoiled. But the way I see it is that the input signal is being compared with a fed back signal simultaneously, and the delays are minimal, and only have a duration which is a small part of any cycle or wave form entering the amp. Where the delays add up to a -180 degree phase lag should occur where the open loop gain has been reduced sufficiently to prevent the NFB from becoming PFB, and oscilation occuring. ppl talk of transient behaviour analomies, and this depends on the HF performance, so the bandwidth of the amp shoulod reach well above 20 kHz, for the phase shift to be low, and correction to phase lags able to be fully applied even at 20 kHz. If ppl want to complain about delays with FB, then they ought to start with the addressing the worse delays with no FB. FB when well applied, seems to do the transients no harm. But if an amp saturates a stage when a crash of cymbals occurs, then the amp just hasn't got a good enough HF response. I like tube amps with wide open loop response before FB is applied, say 70 kHz, and then after 16 dB of FB, the sound is still tubey, but very accurate, with warmth etc preserved, ie, hi-fi.

"Ruud Broens" wrote in message ... : : "Kevin Aylward" wrote in message : ... : : : : : What particular quantum physics "findings" did you have in mind? Actually, this one Feynman had got to know [biologist James] Watson during the sabbatical year that Dick had spent as a 'graduate student' in biology. He had an opportunity to renew the acquaintance when he visited Chicago early in 1967, and when they met Watson gave Feynman a copy of the typescript of what was to become his famous book The Double Helix, about his discovery, together with Francis Crick, of the structure of DNA. Feynman read the book straight through, the same day. He had been accompanied on that trip by David Goodstein, then a young physicist just completing his PhD at Caltech, and late that night Feynman collared Goodstein and told him that he had to read Watson's book -- immediately. Goodstein did as he was told, reading through the night while Feynman paced up and down, or sat doodling on a pad of paper. Some time towards dawn, Goodstein looked up and commented to Feynman that the surprising thing was that Watson had been involved in making such a fundamental advance in science, and yet he had been completely out of touch with what everybody else in his field was doing. Feynman held up the pad he had been doodling on. In the middle, surrounded by all kinds of scribble, was one word, in capitals: DISREGARD. That, he told Goodstein, was the whole point. That was what he had forgotten, and why he had been making so little progress. The way for researchers like himself and Watson to make a breakthrough was to be ignorant of what everybody else was doing and plough their own furrow. [pp. 185-186] What had gone wrong for Feynman was that he had begun taking too seriously the idea that modern knowledge is a collective enterprise. Just trying to keep up with his field had suppressed his own sources of inspiration, which were in his own solitary questions and examinations. This, indeed, is the fate of most research in most disciplines, to make the smallest, least threatening, possible addition to "current knowledge." Anything more would be presumptuous, anything more might elicit the fatal "Don't you know what so-and-so is doing" from a Peer Reviewer, anything more might invite dismissal as some off-the-wall speculation -- not serious work. So Feynman "stopped trying to keep up with the scientific literature or compete with other theorists at their own game, and went back to his roots, comparing experiment with theory, making guesses that were all his own..." [p. 186]. Thus he became productive again, as he had been when he had just been working things out for himself, before becoming a famous physicist. While this is an important lesson for science, it is a supreme lesson for philosophy, where "current knowledge" can be dominated by theories, like Logical Positivism or deconstruction, that are simply incoherent. Trying to keep up with literature like that is a complete waste of time, even if contributions to it earn the praise of reviewers and are snapped up by presitigious journals. To participate in this may prudently recommend itself to the careerist, but it holds little hope of making any real contributions to the progress of philosophy. To philosophy they are assigned with their wives and children, and in spite of Petrarch's povera e nude vai filosofia ["you go poor and nude, philosophy"], they have taken a chance on it. [Arthur Schopenhauer, The World as Will and Representation, Vol. 1, E.F.J. Payne translation, Dover, 1858, p.xxvi] New ideas do not come from committees, and although this dynamic is so well understood as to be part of folk wisdom, researchers in many areas of science or scholarship are so blinded by their own herd mentality, or collectivist ideology, or rent-seeking behavior, that they commonly act, both for themselves and in judgment of others, in denial of it. Of all the "curious" lessons of Richard Feynman's life, this is one of the best. |

I read in sci.electronics.design that John Popelish
wrote (in ) about 'A little feedback worse than none at all?', on Thu, 20 Nov 2003: I think the important fact to keep in mind is that negative feedback does not have much chance of increasing the high harmonics when it is used to suppress the low harmonics, Kevin has already explained how feedback does indeed create high-order harmonics which were not present in the open-loop condition, by intermodulation (in the non-linearity in the forward path through the amplifier) between fed-back harmonics and the fundamental or other fed- back harmonics. The difference between KA and me on this point is basically that KA says that the high-order harmonic amplitudes monotonically decrease as the feedback factor is increased, where as I don't agree that it's monotonic. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

Confronted with the simplest of simple, no freshman in physics would have any problem with, like the doppler question i put to you, you couldn't get it right, simple. What the $#@% are you going on about. This is damn lie. What *exactly* did I say that was incorrect? I made a comment on Doppler. Clearly you did not have sufficient knowledge to do the calculations yourself, so I had to do them for you. Then your ignorance showed that you didn't even understand such a basic calculation. You make a &*%$ing claim here that I did not understand anything, yet you made no argument *whatsoever* to refute my calculations. Your claim is baseless. Explain exactly what I got wrong, or retract your lie. Never mind you conveniently neglected to inform us what bearing this effect, with any musical signal only having such magnitude at oh, say, 1 % of the time, actually has on the perceived sound. Because I assumed that you had some knowledge of the Bessel series expansion of an FM wave. Sadly I was mistaken. You comment here of "only 1% of the time", shows you have not got the *slightest* idea of the mathematics involved here. Your a rank amateur. Let me put you in the picture. V = Vp.sin(Wc.t + m.sin(Wm.t)) This generates a whole series of *continuously* present frequencies, the magnitude of each harmonics weighted by m. The peak value of the frequency shift is the value that one uses to calculate what the spectrum spread is, essentially by Jn(mf). You don't just go, oh well, its only that for a bit of the time, so the frequencies are only on for a bit of the time. You obviously have done no graduate maths whatsoever, so stop making daft claims on things that you can't possible understand. It is well known that frequency modulation is far more audibly detectable that harmonic distortion. I will leave it you as an exercise to look up what the amplitudes of the harmonics of an FM wave when it has a *peak* modulation index of 0.3%. And then the whole raft of unoutspoken beliefs you hold, And just art thous unoutspoketh beliefs spoketh? most of them blatantly wrong, eg. that perception of distortion is simply a linear additional effect, so how can 0.1 % of X be noticiable when there is 1 % of Y.... I said no such thing. Your just making this up as you go along. What I did say was that if distortion was below 0.01%, it is inaudible. I made no claim whatsoever that there was a linear relation between distortion and perceived audio detriment. *Show* me such a quote, or retract your lies. The deal here, is that you have failed to refute anything I have said, therefore you simple lie about what I have said. The record is clear on this for all to see. All your doing here is embarrassing yourself. In fact, you remind me a lot of the athropologists of the old days, who did nothing but reasoning about their findings from their 'superiour white man' position, ascribing any find to stupidity, primitivity, etc. For instance, there was this tribe who had this ritual, where if someone got seriously ill, it ended with hanging a particular produce from a tree, near a river, for seven days, then brew some medicine from that. Stupid, placebo effect, etc. Until some biochemist tracked this story and found out that precisely these circumstances promoted the growth of a mold that had very penicilline-like effects... My comments are made by my years of experiance in said subject matters. http://www.anasoft.co.uk/founder.html http://www.anasoft.co.uk/studiomaster/Studiomaster.htm http://www.anasoft.co.uk/EE/index.html http://www.anasoft.co.uk/physics/gr/index.html The fact that you are lacking in any such qualifications is evidence of your inability to understand my knowledge, not that mine is lacking.

"Ruud Broens" wrote in message ...
Feynman had got to know [biologist James] Watson during the sabbatical year that Dick had spent as a 'graduate student' in biology. He had an opportunity to renew the acquaintance when he visited Chicago early in 1967, and when they met Watson gave Feynman a copy of the typescript of what was to become his famous book The Double Helix, about his discovery, together with Francis Crick, of the structure of DNA. Feynman read the book straight through, the same day. He had been accompanied on that trip by David Goodstein, then a young physicist just completing his PhD at Caltech, and late that night Feynman collared Goodstein and told him that he had to read Watson's book -- immediately. Goodstein did as he was told, reading through the night while Feynman paced up and down, or sat doodling on a pad of paper. Some time towards dawn, Goodstein looked up and commented to Feynman that the surprising thing was that Watson had been involved in making such a fundamental advance in science, and yet he had been completely out of touch with what everybody else in his field was doing. Feynman held up the pad he had been doodling on. In the middle, surrounded by all kinds of scribble, was one word, in capitals: DISREGARD. That, he told Goodstein, was the whole point. That was what he had forgotten, and why he had been making so little progress. The way for researchers like himself and Watson to make a breakthrough was to be ignorant of what everybody else was doing and plough their own furrow. [pp. 185-186] What had gone wrong for Feynman was that he had begun taking too seriously the idea that modern knowledge is a collective enterprise. Just trying to keep up with his field had suppressed his own sources of inspiration, which were in his own solitary questions and examinations. This, indeed, is the fate of most research in most disciplines, to make the smallest, least threatening, possible addition to "current knowledge." Anything more would be presumptuous, anything more might elicit the fatal "Don't you know what so-and-so is doing" from a Peer Reviewer, anything more might invite dismissal as some off-the-wall speculation -- not serious work. So Feynman "stopped trying to keep up with the scientific literature or compete with other theorists at their own game, and went back to his roots, comparing experiment with theory, making guesses that were all his own..." [p. 186]. Thus he became productive again, as he had been when he had just been working things out for himself, before becoming a famous physicist. While this is an important lesson for science, it is a supreme lesson for philosophy, where "current knowledge" can be dominated by theories, like Logical Positivism or deconstruction, that are simply incoherent. Trying to keep up with literature like that is a complete waste of time, even if contributions to it earn the praise of reviewers and are snapped up by presitigious journals. To participate in this may prudently recommend itself to the careerist, but it holds little hope of making any real contributions to the progress of philosophy. To philosophy they are assigned with their wives and children, and in spite of Petrarch's povera e nude vai filosofia ["you go poor and nude, philosophy"], they have taken a chance on it. [Arthur Schopenhauer, The World as Will and Representation, Vol. 1, E.F.J. Payne translation, Dover, 1858, p.xxvi] New ideas do not come from committees, and although this dynamic is so well understood as to be part of folk wisdom, researchers in many areas of science or scholarship are so blinded by their own herd mentality, or collectivist ideology, or rent-seeking behavior, that they commonly act, both for themselves and in judgment of others, in denial of it. Of all the "curious" lessons of Richard Feynman's life, this is one of the best. Hi Ruud. A nice account. New ideas do not come from committees, I cant help but offer an elementary point, and that is that it is both methods that produce results, not just one or the other. The sum of the progress we have today has come from using both approaches. Each has significant pros and cons, and tends to produce a different style of result. But clearly both have produced plenty of progress. The reason most people produce only minor progress is thats all theyre able to do. This is the same thing as you said, put differently, that they dismiss anything threatening, thus blocking their own path. And that is an entire mindset no less. It is not a minor block to sidestep, it is what makes people limited, what differentiates the movers from the mediocre. One can not get free from the mindset that limits people easily, it is a mindset not a thought. Its late and I'm probably as clear as mud... to break out of the mindset one is taught is something few manage. And that, to me, isnt just about electronics, but the many seemingly unrelated ideas that impact on how I approach tronics. Ie to grasp a subject one has to grasp other subjects: in the case of electronics one has to grasp concepts of business and the people. Bed. Regards, NT This thread reminds me of my discussions with Kevin on medical matters. |

It is not a minor block to sidestep, it is what makes people limited, what differentiates the movers from the mediocre. One can not get free from the mindset that limits people easily, it is a mindset not a thought. The reason for this, is of course, because our brains are Darwinian Machines, http://www.anasoft.co.uk/replicators/intelligence.html. That is, they operate by variation, selection and replication. Natural selection of memes is a slow process. The Darwinian process results in us preferentially coping popular memes, and rejecting unpopular memes, because those selections, by assumption, are the memes that are replicating the fastest. "What we observe mostly, is that which replicates the most". So, our brain cant operate in any other way. Snippet from above link. ******** Electronic Engineer as a Darwinian Machine An Electronic Engineer copies existing circuits into his brain. He than varies those circuits to obtain new ones. He than analyses them to select the good ones. It is held that no other fundamental process are required. An Electronic Engineer is thus a Darwinian Machine, as are all of us. ********** Its late and I'm probably as clear as mud... to break out of the mindset one is taught is something few manage.

Ahh, but it 'just happens' all there is to it, some 'critical mass'. have an estimate there, at your choosing, say of MB of memory use, # lines of code, # of nodal net points, whatever, where you can definitely say: he, we've got consciousness right here, it's happening ! ,then see how that computes with say the brainsize of a worm,, or where, in fact, would *you* say in the animal kingdom 'starts' conscious behaviour ? Consider even the brain of a moth, brain smaller than a pinhead. Yet capable of quite a bit, consciousness, and much more. Consider the complexity of the entire internet, with all the computers that are online at any one moment, each with its own added complexity.

You should take up some german lessons, Kevin. They *are* having this reputation for thorougness, gruendlichheit, justly so.

Many types of drivers are never piston like. Regards, NT |

What do you think, MDHJWH, is there hope yet for a decent publication coming from Kevin Aylward if he hires a female co-writer to make it pallatable ? And what kind of publication is it you refer too young man ? These days 'decent' covers a multitude of sins !

Whence this capacity to deal with novelty? I don't see it as a big deal at all. Language is a way of coding thought for transmission to others. One might as well wonder how it comes about that if you learn 26 characters in Morse code, you can send and receive messages of unlimited length and complexity. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?

The 211 is hot, large, and glows and pulses with life, and upstanding, ( and delightful!) But the best things in life, including sex, are unnerving, and judging by the sheer mountains of books, paintings, and music about love, then sex is a threat, but one which few will ignore for long. Now we have the symbol of the male phallus hitting us in the eye every time we see a tube, but what is the audio equivalent of the female equipments? Patrick Turner. |

More research in this area could advance our understanding of what the conditions for machine self- awareness to emerge actually are. Its a difficult problem. But for me, I am reasonably convinced it must use many independent processors. A single computer won't cut the mustard. The human brain is of the order of 100 Billion little Darwinian computers all interconnected in a very complicated manner. Sensors by themselves are not key. We can have someone becoming deaf dumb and blind, but still being conscious. However, with no inputs whatsoever, in the long run, I think consciousness would probably collapse by running amuck.

Exactly my point 'standard 1-10%...', not only silly, but easy to come up with a zillion examples of it being otherwise, for some driver, at some range, etc.. Using PA drivers here as example, because at these levels, apart from having cone excursion that's barely visible, thus nothing much "dopplering" going on there, there *is* piston movement.
