"ad" wrote in message ... Bill Hobba wrote: Tom it is usually not difficult to see when an argument turns away from science and ventures into philosophy. Take for example the notion of time. To do physics you simply need to assume time is what is read by clocks. It is a fact that one can do science with such a simple notion - that this is true is beyond question. But such is not satisfying to philosophers and they mount all sorts of arguments such as there must be some underlying reality where time exists independent of clocks or that reality is what instruments tell us and that is all there is or similar philosophical stuff. But such is irrelevant to science as can be seen by looking at exactly how each philosophical position will affect experimental results. Since there is none is not relevant to science. Thus if something is bad philosophy it does not follow it is bad physics because providing it has no experimental consequences then it is irrelevant to physics. Eg some consider that Euclidan geomtry exists a-priori (I belive Kant held that view). Others like Russell claim this is bad philosphy because it is "a theory of mathematical reasoning according to which the inference is never strictly logical, but always requires...'intuition'. The whole trend of modern mathematics...has been against this Kantian theory." But physics does not really care if it is bad philosphy or not. A theories correspondence with expriment is all that coutns. Bill If you really believe that then it's very sad. Is physics still really stuck in the dark ages like that? Don't they teach how to think in physics courses? I am self taught in physics but am formally trained in mathematics to masters level. That it is how you are taught in applied mathematics I can vouch for. And no one who has any acquaintance with mathematics can doubt it requires thought, that its practitioners are trained in how to think, and that it has made considerable progress well beyond the dark ages - with that progress underpinning much of the advancement mankind as whole has made. Actually no one who has any acquaintance with physics can doubt the same applies to it - but since I have no formal qualifications I will not push the point. I think it is sad that people who hold the view I espoused above make progress and those that bemoan it as sad seldom seem to. For example what progress has philosophy made other than to understand the issues better? - philosophers never seem to actually agree on anything - science at least agrees on the results of experiment and in broad terms on the scientific method. Or do you think that Bertrand Russell, who wrote the quote I gave and held similar views (not the same but similar) was unable to think and stuck in the dark ages? Pull the other one - it plays jingle bells. Bill |

That is one obvious consequence of 'A theories correspondence with experiment is all that counts'; but reasoning is not your strong suit. Actually in your case I would settle for simple coherency. Time, Mr. Hobba, is duration, whether you and your clock exists. And duration match some movement in space, which is measured by the length of the path of movement, it is the so-called distance, while movement itself is measured by the speed of movement, it is the so-called velocity. All of it without the presence of you and your clock, and even without your observation at all. Make a prediction at variance with current theories with your gibberish. Can't do that? - then it is scientifically of zero value. If, however you want to do physics, which I doubt, you have to consider whether your clock is too fast or too slow. If it is moving, or if it is at rest. If some external forces may effect your clock, which is made of a good many massive parts effected to expansion or contraction by their temperature, as also by the viscosity of the lubrication of the working parts, and - first and foremost - by the (variable?) force(s?) driving your clock, that constantly interacts with the physical fields and forces mediated by the space-time- energy continuum of the aether, and do so by enduring exchange of radiant energy between your clock and the aether. You mean this aether that has never been detected? Wake up from your delusions. All that philosophical mumbo jumbo should be basic knowledge to you Mr. Hobba, so when do you begin speak physics of the space-time-energy continuum which is The Aether, as it has been in countless æons of time, - for the old Greeks as for us meaning from eternity by duration of concept, implicating that it be so also for ever, independent of any human definition or description? So tell us now, what is physics about? See a dicitonary - The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics. And what should aether physics be about? Beats me. Before deciding that it might be a good idea to actually detect it. Will you please get to physics Bill, if this is some physics news group, and not about your private and, as it seems, very primitive philosophy, which you probably have less idea about than about physics and the history of physics? Sure - as soon as crackpots like yourself stop deluding us with rubbish about an aether that has never been detected. Bill |

It is definitely not "empty space in which the Universe sits". You will never detect it because you believe you are deluded. Hence you deny solid logic and scientific facts asking for predictions from crackpots you stubbornly assert are worse morons than yourself. This is your philosophy and creed of some weired religion in which you hope to find your salvation. Therefore you will never get to physics, and as regards your primitive line of thoughts, you will probably never be able to understand how science works and why civilized manners are preferred in scientific discussions. - I predict that! That is quite O.K. Don't worry, be happy! But please do not pretend that you have anything worth to say about science. When you make postings "to learn science", as you coin it, please do not waste other peoples' time with your funny and wrong ideas about their personallity and qualifications or with your experiencies about remedies and drugs, you think may help them as it has helped yourself. Don't do that, because it is simply irrelevant noise, which has nothing to say in science. If you do not agree in some statement, simply show why you believe it is false or wrong. If you agree to something and see further aspects that may develop the idea and further discussion, give your opinion without your personal values about those with whom you interlope. Otherwise, keep happily silent. Be good, and have a nice day! Ole |

A theories correspondence with expriment is all that coutns. Is this Billy Hobba talking a kind of "philosophical mumbo jumbo"? And what has that with the aether and aether-physics to do? So sorry your reasoning ability is so impaired that you consider the fact the aether has never been detected is not relevant to its existence. That is one obvious consequence of 'A theories correspondence with experiment is all that counts'; but reasoning is not your strong suit. Actually in your case I would settle for simple coherency. Time, Mr. Hobba, is duration, whether you and your clock exists. And duration match some movement in space, which is measured by the length of the path of movement, it is the so-called distance, while movement itself is measured by the speed of movement, it is the so-called velocity. All of it without the presence of you and your clock, and even without your observation at all. Make a prediction at variance with current theories with your gibberish. Can't do that? - then it is scientifically of zero value. If, however you want to do physics, which I doubt, you have to consider whether your clock is too fast or too slow. If it is moving, or if it is at rest. If some external forces may effect your clock, which is made of a good many massive parts effected to expansion or contraction by their temperature, as also by the viscosity of the lubrication of the working parts, and - first and foremost - by the (variable?) force(s?) driving your clock, that constantly interacts with the physical fields and forces mediated by the space-time- energy continuum of the aether, and do so by enduring exchange of radiant energy between your clock and the aether. You mean this aether that has never been detected? Wake up from your delusions. All that philosophical mumbo jumbo should be basic knowledge to you Mr. Hobba, so when do you begin speak physics of the space-time-energy continuum which is The Aether, as it has been in countless æons of time, - for the old Greeks as for us meaning from eternity by duration of concept, implicating that it be so also for ever, independent of any human definition or description? So tell us now, what is physics about? See a dicitonary - The science of matter and energy and of interactions between the two, grouped in traditional fields such as acoustics, optics, mechanics, thermodynamics, and electromagnetism, as well as in modern extensions including atomic and nuclear physics, cryogenics, solid-state physics, particle physics, and plasma physics. And what should aether physics be about? Beats me. Before deciding that it might be a good idea to actually detect it. Will you please get to physics Bill, if this is some physics news group, and not about your private and, as it seems, very primitive philosophy, which you probably have less idea about than about physics and the history of physics? Sure - as soon as crackpots like yourself stop deluding us with rubbish about an aether that has never been detected. Dear Bill, You have been told what the aether is and where to find it. It is definitely not "empty space in which the Universe sits". Please, carefully read this quote, and if you disgree with Bohm, be kind enough to explain why. -- Laurent ------------------------- "Well, perhaps we should finish with this business about empty space. If you follow through the mathematics of the present Quantum Theory, it treats the particle as what is called the quantized state of the field, that is, as a field spread over space but in some mysterious way with a quantum of energy. Now each wave in the field has a certain quantum of energy proportional to its frequency. And if you take the electromagnetic field, for example,in empty space, every wave has what is called a zero point energy below which it cannot go, even when there is no energy available. If you were to add up all the waves in any region of empty space you would find that they have an infinite amount of energy because an infinite number of waves are possible. Now, however, you may have reason to suppose that the energy may not be infinite, that maybe you cannot keep on adding waves that are shorter and shorter, each contributing to the energy. There may be some shortest possible wave, and then the total number of waves would be finite and the energy would also be finite. Now, you have to ask what would be the shortest length and there seems to be reason to suspect that the gravitational theory may provide us with some shortest length, for according to general relativity, the gravitational field also determines what is meant by "length" and metric. If you said the gravitational field was made up of waves which were quantized in this way, you would find that there was a certain length below which the gravitational field would become undefinable because of this zero point movement and you wouldn't be able to define length. Therefore, you could say the property of measurement, length, fades out at very short distance and you'd find the place at which it fades out would be about 10^ -33 cm. That is a very short distance because the shortest distances that physicist have ever probed so far might be 10^ -16 cm. or so, and that's a long way to go. If you then compute the amount of energy that would be in space, with that shortest possible wave length, then it turns out that the energy in one cubic centimeter would be immensely beyond the total energy of all the known matter in the universe. Present theory says that the vacuum contains all this energy which is then ignored because it cannot be measured by an instrument. The philosophy being that only what could be measured by an instrument could be considered to be real, because the only point about the reality of physics is the result of instruments, except that it is also said that there are particles there that cannot be seen in instruments at all. What you can say is that the present state of theoretical physics implies that empty space has all this energy, and matter is a slight increase of the energy, and therefore matter is like a small ripple on this tremendous ocean of energy, having some relative stability, and being manifest. Now, therefore, my suggestion is that this implicate order implies a reality immensely beyond what we call matter. Matter itself is merely a ripple in this background. If you take a crystal which is at absolute zero it does not scatter electrons. They go through it as if it were empty. And as soon as you raise the temperature and (produce) inhomogenities, they scatter. Now, if you used those electrons to observe the crystal (e.g., by focusing them with an electron lens to make an image), all you would see would be these little inhomogeneities and you would say they are what exists and the crystal is what does not exist. Right? I think this is a familiar idea, namely to say that what we see immediately is really a very superficial affair. However, the positivist used to say that what we see immediately is all there is or all that counts, and that our ideas must simply correlate what we see immediately. So now, with this vast reserve of energy and empty space, saying that matter itself is that small wave on empty space, then we could better say that the space as a whole (and we start from the general space) is the ground of existence, and we are in it. So the space doesn't separate us, it unites us. Therefore it's like saying that there are two separate points and a certain dotted line connects them, which shows how we think they are related, or to say there is a real line and that the points are abstractions from that.The line is the reality and the points are abstractions. In that sense we say that there are no separate people, you see, but that 'that' is an abstraction which comes by taking certain features as abstracted and self-existent." --- David Bohm |
