Consider some entity A. It is made of entities B and C. A has properties which come from the properties of B and C plus some influence from the relationship between B and C. For example the mass of A might be the sum of the masses of B and C plus the binding energy of the pair. As you go down the scale, eventually you come to something fundamental which is not composed of other things, and yet it must have some properties of its own. I think you just enjoy arguing, George. Probably, but what I said is still valid. I expected you to reply that an electron is a fundamental particle yet string theory says it has structure - a ring of energy. My reply would be that "ring-like" is a property rather than indicative of construction from lesser items. Quite often I feel words can be ambiguous and exploring alternative meanings for, in this case, "structure" can be useful in clarifying what we mean. Theories, theories....nobody really knows.... I see you still haven't learned what the word theory means in science. However, if single ONE bullet is fired at the target, it has zero probability of landing anywhere other than at the point where the gun was aimed. (please don't mention wind shear) No, it has exactly the same probability of landing at any location as each of the thousand. No it doesn't!!!!!! Yes it does, that is basic probability theory. Probability is not a cause of anything. It's a result. Nobody said anything about probability being causal. George, like many others, you are completely misinterpreting the role of statistics, which is a science dealing with the outcome of multiple events. Henry, I'm not talking about statistics, I'm talking about probability. There is a subtle distinction. Mathematics, on the other hand, is designed to analyse or predict single events. Maybe you should study probability a bit before trying to discuss it. All those bullets that were normally distributed around the bull landed exactly where they did for purely physical reasons. Where the bullet will strike is precisely determined BEFORE it is fired. Even factors like the nerve movements of the shooter and the wind movements are precisely predetermined. There is no way anyone could produce a mathematical model to predict the outcome but it is still theoretically possible. Statistics is the most misinterpreted science of all.... Indeed, though your mistake above is less common than others. The key here is that the pprobability for each bullet is unaffected by the existence of any preceding shot. That is not related to my statement. You said that a thosand bullets would be spread but a single bullet would not, hence the implication is that the first bullet always goes where it is aimed and subsequent bullets go elsewhere because of the previous one(s). That is not the case, the first bullet has as much chance of landing at some off-centre point as any other. You can say that BEFORE the bullet is fired...because the conditions that cause the bullet to land where it does are random. However, that does not alter the fact that each bullet hits where it does for specific physical reasons that are theoretically capable of being mathematically analysed and explained. Whether or not true randomicity exists is a big question. No, it's not a question at all, it is proven beyond any doubt. It is similar to tossing an unbiassed coin, the probability is 50:50 regardless of the outcome of preceding tosses, only the variable is 2D real (location on the target) rather than binary (heads or tails). Yes I know that George. Then why did you say "No it doesn't!!!!!!" ? The bullet is destined to hit exactly where it does from the moment it is fired. Chance doesn't enter into it... Not true I'm afraid, but it doesn't alter the fact that you said "No it doesn't" in one case and "Yes I know that" a few lines later. It's hard to discuss anything when you can't even express a consistent view in a single post. If you drop a thousand ball bearings on the floor they will end up normally distributed around the centre....BUT that does not alter the fact thta there was a precise physical reason why every one came to rest right where it did. Mostly, the scatter is dominated by slight variations at the macroscopic level, but a small amount of uncertainty is also an intrinsic property of any individual particle so if you repeat that with electrons there is a lower limit of spread beyond that from the lack of perfect knowledge. Einstein didn't like that but it has been proven experimentally beyond any doubt. Newton's clockwork and fully deterministic universe isn't ours. Nobody has demonstrated that true randomicty exists, at any level. Sorry Henry, your decades out of date again. Just the aggregate, The way I see it is that a monochromatic beam is just a large number of identical photons with that particular 'wavelength'. Yes. A grating deflects an individual photon depending on the colour of that beam, not the rate at which photons arrive. I'm thinking of say a dim red laser with a flux of a few photons per minute. Like the coin tosses, each one is deflected purely on its intrinsic properties. If all the photons are identical, should they all be deflected by the same amount? To within the intrinsic uncertainty of the energy property. That means there is a fundamental lower limit to line width. You can think of that either as the (gaussian) spectrum of the line showing the power in each frequency that you get from a Fourier transform of the received sine wave or as a histogram of the photon energies (which will produce a small spread of deflection angles) or by transforming to the time domain as the phase jitter on the RF sine wave. They are all just different coneptual models of the same feature. I would like to think that the diffraction angle depends on the actual phase of the photon's INTRINSIC oscillation when it strikes the grating.. Frequency (or equivalently wavelength), not phase. White light is a mixture. Yes. When it hits a grating each photon deflects depending only on its own properties and not the properties of other photons that arrive some seconds earlier or later. yes. That would have to be right. Excellent. That is a major agreement Henry. A radio signal is a mixture in which groups of individual photons form sine shaped 'bunches' which move along. ..somewhat like a water wave except the photons move back and forth rather than up and down. No, radio is no different to light, it just has much lower energy per photon. I don't agree with this at all...and I don't think many others would either. I'm afraid you are wrong on that, there might be a few cranks around who would dispute it but it has been known in scientific circles for well over a century. Consider microwaves hitting a wire grid. Each photon in the wave is deflected by an angle that depends only on its own properties independent of any others. But there is also a second diffraction based on the microwave 'wavelength'. Same thing. Sure, I expect the formula to be different in BaTh, but the argument still holds, that energy is deposited where the photon lands, not somehwere else. That's probably OK for monochromatic light but you can't deduce that the same will apply to, say, RF. They are both just EM, all the rules must apply to everything from ELF at a few Hz up to gamma rays. Sorry George, I cannot imagine a single photon that is maybe 1 lightsecond in length and expands as a radio signal diverges. Do you think it expands forever? Photons are particles Henry. Look at the example I gave of the sodium doublet. The line width has to be less than 6A while the mean wavelength is 5893A. The Zeeman effect produces individual lines with far smaller spacing. A line of 5893A wavelength and width of 0.003A must contain more than 1.7 million cycles so would be more than 1 light second long in a classical wave model, yet it is absorbed instantly by a single electron in the photo-electric effect. Photons are particles and energy is an intrinsic property. The probability of a single photon being measured at some location after deflection from a grating depends on the energy, and the maths that describes that dependence includes a sine function which is related to energy. Planck's constant allows us to express the energy in the classical "frequency" concept which can then be used in the maths. You see, I believe that eventually EM beams become so weak due to square law divergence that genuine 'nothing' appears between individual photons and their fields. "Field" is just a name for the statistical summed effect of many photons, there is nothing between them. That's why I invented Wilsonian nort-holes. Everyone else calls it the vaccuum through which the photons move. This argument is not about how gratings behave according to BaTh. Of course it is. The BaTh doesn't need gratings to verify it. BaTh needs a version of the grating equation. Working that out will tell you about the rules for dealing with reflection in BaTh which is something you currently don't know. Once you do that you could apply it to Sagnac's experiment without having to assume all the mirrors are at the same radius as you do at present. I believe the sagnac effect is due to an entirely different factor...such as a local EM frame that behaves like an aether. I don't care what you belive, it is a fact that the measued speed is independent of the speed of the source. I'm starting to think that local EM reference frames are everywhere around us, ...inside accelerators, etc.... The BaTh only holds 100% in truly empty space. Even the IGM isn't "truly empty" so basically you are simply back to LET to explain both the MMX and Sagnac. Water waves carry longitudinal energy...but the individual molecules go up and down. Their vertical KE is NOT what is carried with the wave. The wave energy is deposited where the waves lap the shore, not somewhere else. But the energy of the vertically oscillating water molecules is continuously being dampened out and absorbed as heat in the ocean. Yes, and the heat is deposited at the location of the wave, not elsewhere. Underneath a traveling water wave, the individual molecules move in roughly elliptical orbits....which accounts for the macroscopic movement of water and energy. ...but the molecules move laterally far less than the wave crests. CMIIW.. Sure but a wave on the sea moves the sand on the shore, it doesn't deposit its energy a mile inland. Wavelength and/or frequency. Since nobody has a clue what photon 'wavelength' or 'frequency' actually signify, that is a pretty meaningless statement. Speak for yourself. Come on George, you don't have any kind of model for a photon. You think it's just a couple of sinewaves drawn at right angles on paper. No, I think it is a fundamental particle like an electron which has the property of carrying energy (and others). I think when the charge is taken to some destination, the car also arrives at the same place. You can't send the car to Boston and have the charge arrive in Cairo which is what you are suggesting. Beyond that discussions of their length are irrelevant, the length has no analog in the photon. How do you know. Because your suggestion is equivalent to saying the heat produced by friction in an ocean wave can be deposited inland. George, you know how water waves can be diffracted, for instance by a row of vertical bars. Yes, and the energy of the waves is then carried in another direction to be deposited where the waves go. Do you really believe that the water molecules that go up and down near the bars are the ones that end up making the diffraction pattern maybe 100 metres away? No Henry, exactly my point. That is what you are telling me, that the grating angle for the wave is not the same as that for the photons composing the wave. Henry, I think we have maybe got a handle on this, in your grating equation if you have red laser light arriving at a level of one photon per second, would you use the frequency of the red light or the 1Hz rate of one photon per second to work out the deflection angle. I say it is that of the light regardless of the arrival rate, you are telling me the wave energy goes to one place at an angle determined by the 1Hz figure while the photons themselves go to the location given by the red light frequency. the should be another very weak energy build up where the 1 hz is diffracted. How about modifying your experiment to make the 1 Hz sinusoidal. How about you calculate how much energy BaTh says is in this extra mode you have invented. For a fairly bright source with random arrival times (e.g. a sodium lamp where the photons are emitted thermally) there should be a background continuum under the lines. Make your prediction of that level and then research the literature. The concept matches the data very well. It makes no sense though, how can the energy go anywhere other than where the photons go? Strange things happen. Perhaps, but for your bizarre idea to 'match the data very well' requires _all_ the energy to go where the 1Hz deflection predicts and none to go with the photons. As I said, it makes no sense. George |

On Fri, 4 May 2007 14:16:37 +0100, "George Dishman" http://www.hqrd.hitachi.co.jp/em/doubleslit.cfm Yes I'm familiar with that kind of result. De Broglie waves are quite amazing really. It shows that matter and 'fields' are not very far apart in nature. George, there is nothing here that surprises me. Single photons making up a monochromatic beam should have the same wavelength as the beam itself. The beam is just 'lots of them'. Finally, you have cottoned on to what I have been saying. In the experiment they used a current of 10 electrons per second. Obviously the diffraction pattern is not what you would predict using a frequency of 10Hz in your "grating equation". Each electron behaves entirely independently of the others and the pattern that builds up is controlled by the intrinsic properties of an electron. If you use the interference pattern via Huygens to work out a wavelength, it is the wavelength of an electron that you get, not the 29979245.8m wavelength that corresponds to a frequency of 10Hz. Yes George, that isn't surprising. The thing is diffracting the De Broglie waves of the electrons...whatever they might be. Now try diffracting a 30000 hz radio wave. It WILL use the corresponding wavelength. Yep, exactly the same, but in your other post you claim there should be some energy deposuted from the electron beam at the angle corresponding to 10Hz even though all the electrons go where the De Broglie wavelength says they should. Incidentally, did you notice at the top it says "This detector was specially modified for electrons from the photon detector produced by Hamamatsu Photonics (PIAS)." It is just a photomultiplier with the front end photoelectric element removed. It detects single electrons, not single photons... Henry, it_IS_ a PM tube but without the photoelectric emitter on the front which of course ejects one electron per photon. How did you think a PM worked? George |

As it is, my computations assuming Newtonia on supernovae suggest that the peak would be very rounded; the photons from the leading edge of the exploding sphere would reach us first, with low but growing luminosity. The maximum would be at the point where the light from the gases from the cross-section of the star perpendicular to our view line -- which is travelling at c relative to us -- reaches us. The brightness would then taper off, in a manner much like the brightness increase, maybe a bit slower since 1.0/.9 - 1.0 1.0 - 1.0/1.1 . Since at least one measurement suggests an explosion speed of 1/10 c, one can perform these calculations without much difficulty, and the results would depend on distance. -- #191, GNU and improved. -- Posted via a free Usenet account from http://www.teranews.com |

To detect a trapped single photon, the mean thermal noise needs to be below the photon energy so that the tank would randomly have zero or one photon in it, and very occasionally more than one. Incidentally would the minimum energy be half the quantum level? I seem to remember from my QM courses many years ago that the levels for a tank are h.nu.(n+1/2) for n=0,1,2,... George |

Henry, why don't you just accept that photons from a laser deflect by an angle determined by the colour of the light and not the time between photon arrivals, you did in a second post and disagreed in a third. I distinguish between waves that are intrinsic to individual photons and waves made from density distributions in large groups of photons. George, when signals are sent through optical fibres, how are they modulated? You should know that the 'carrier light' can have a wide range of wavelengths and still do the job. But we don't agree that the rate within a photon is far greater than the rate BETWEEN photons. The rate is fixed by your speed equalisation factor. The inside of a photon has completely different properties from the space between photons. Why should the two be the same? Space has only one set of properties. Ballistic theory says the speed is c+v tending towards c and that theory applies to all the waves in your photon packet. George, when you talk about the speed of anything you must always provide a reference. You should know that by now. Are you denying ballistic theory says the speed is c+v relative to the source? You didn't mean that, I hope. You meant 'c relative to the source, c+v relative to the observer'. Are you denying it says the speed is asymptotic to c/n relative to a medium where n is the refractive index of that medium? I'm just applying your theory consistently. I'm not denying that.... but strees that light entering such a medium might never get even close to c/n (wrt the medium frame) before it passes right through.. Ballistic theory says the speed of EM is INITIALLY c wrt its source and c+v wrt an object moving at -v wrt the source... Refuted by De Sitter's argument. Not refuted by DeSitters wrong argument. ... what happens to the light during travel is not really part of the basic theory although we now suspect that it experiences speed changes and speed unification.... If it isn't part of your theory, it fails, we should see multiple images. That idea was thrown out years ago. Unification takes care of multiple imagery. No star light seems to ever overtakes other light....but there might be instances where it does. So are many orbit periods. No orbital periods are more stable and don't show the discontinuous phase changes of Cepheids. There are plenty of complex orbit systems that would cause that effect. Nope, you can't gete a nice consistent value for years with step discontinuities. George, our own sun moves in a complex orbit around its barycentre with all the planets. Those small anomalies would show up in its brightness curve 50000 LYs away. Yes, and they would be smooth changes indicative of Keplerian orbits. Cepheids show non-Keplerian changes. they don't. Their curves are quite Keplerian. Even B type Cepheids exhibit brightness curves that are fully in accord with Keplerian binary systems. There can also be a long term Vdoppler shift caused by a whole cepheid system being in a long period orbit around a galactic centre or similar. Sure, proper motion is significant but again it cannot produce phase steps. They are not very common. ... True but they exist falsifying your hypothesis. They don't falsify it at all. The motions are obviously complex. Other bodies and factors are involved. The idea that individual detections "could barely be seen above the noise" is ********, the detectors are far less noisy than you imagine. That is obvious in the stills. They aren't photons. They're electrons.. Yes, and that is how PM tubes work (at least early ones). The stills _are_ a converted PM detector and if there was a high noise level it would be visible in the photographs. The theory says a photon (or several) knocks a single electron out of an atom. The electron is then accelerated, causing an avalanche that is visually recordable. The fact that the principle can be used to detect single photons is an added bonus. http://ophelia.princeton.edu/~page/single_photon.html There is no PM in this experiment. "The Hamamatsu camera is a remarkable device. In essence, it has two successive micro-channel plates followed by a CCD chip." What do you think that is then? It accelerates single electrons, emitting photon bursts. These are what the thing sees. Yes, and in a photo-multiplier the first electron is emitted by the photo-electric effect. The whole amplification and detection process is identical. It is in fact an actual PM camera with just the front end removed so you can see the noise level for yourself. In any case, you aren't 'seeing' a single photon. You are merely verifying that an electron can be released by one. George, you keep telling me I have to match observed data. A theory is required to be self-consistent as well as matching the data. If I assume K is 1, nothing matches. The velocities do. The luminosity is then seen to be intrinsic in eclipsing binaries and Cepheids. A small value of 'extinction' distance is required for EF Dra and the pulsars which is entirely consistent. Your theory survives all these tests but in every case where we can tell (there's no phase reference for Cepheids) only VDoppler can be seen. George, if it weren't for the fact that a great many brightness curves can be matched with BaTh, I would take the easy way out and probably agree with you. However, since logic tells us that there is no mechanism outside of fairyland which would cause all starlight in the universe to travel towards little planet Earth at precisely c, and since I CAN match brightness curves very nicely, I will prefer to continue along my present very interesting and fruitful path. If I assume it has a value of maybe 10000, then everything falls into place, I can match hundreds of brightness curves in phase and magnitude with velocity curves. But it is then self-contradictory so fails to be a theory in the first place. It isn't. It can have a value of 10000 and not dominate VDoppler. ..but ADoppler will still dominate as far as brightness is concerned becasue the 10000 is not instrumental in the bunching procedure. George, this is how exepriment physics operates. If K is not = 1, then all data is matched. What is the logical conclusion? Without K=1 you cannot match simple Doppler measurements in the lab and K1 conflicts with c+v for the speed, it is self-contradictory so proves itself wrong. I now consider that Labs create and constitute their own strong EM FoRs. that uses frequency can equally well be written using speed and wavelength. You really need to find out what your equation is before you make a bigger fool of yourself. George, I can say whatever I like and you can't prove me wrong. Yes I can if what you say conflicts with what you say, one or the other is wrong. Either you know frequency is the independent variable in the equation or you don't know what the equation is, both cannot be true. Nobody has moved a grating in remote space ... Itrrelevant, what equation for aa grating deflection angle is derived from the BaTh basic equations by pure maths? I will soon produce the relevant diagram for htis. It should be pretty obvious. THE BLOODY BRIGHTNESS PEAK IS EXACTLY IN PHASE WITH THE CENTRE OF THE ECLIPSE. Yes, but the observed velocity peak is exactly between the eclipses, and the period of the orbit is double the period of the eclipses giving a 45 degree error. Oh, Ok. I wasn't looking at that. OK, you need to have a more detailed look. It isn't trivial. No, it certainly isn't. I just hadn't gotten around to it. Yes that's interesting...and backs up my theory that unification is pretty quick near short period binaries and also that K 1. It means there is still enough ADoppler to account for the brightness variation although the individual photons are essentially VDoppler shifted. I doubt it, but remember the eclipses will fully explain the luminosity anyway so you don't need to worry about matching that curve at all, only the velocity curves. The spectral shift is the same no matter if part of the star is hidden as long as there is enough light to measure. The curves don't really tell us much because there are only a few points to go on. Which is the BaTh prediction. Wrong. If you had used you program instead of faking your results, you would have found that yourself. Well you can see a better curve now. http://www.users.bigpond.com/hewn/efdra.jpg As I write it still matches the luminosity instead of the velocities. Yes. K is obviously large for close binaries...but not so large for cepheids. Right, the 'wavelength' of the photons is what determines the grating deflection angle. ...and that 'wavelength' cannot possibly change just because the GRATING moves. I have explained several times why BaTh says it _can_ change. You need to do the derivation to find out if it predicts that it does. BaTh says the difraction angles are sensitive to 'wavecrest arrival rate'. I will illustrate the principle today if I get a chance. The FREQUENCY of wavecrest arrival is what the BaTh uses. You can't seriously be trying to tell me you would put 1Hz into the BaTh equation for the grating deflection, are you? I certainly gave you credit for more understanding than that. The grating angle depends on the colour of the light, not how many photons per second arrive. That's OK for light....but not for generated radio waves. Both are EM, any theory must be equally aplplicable to both. But George, you are not distinguishing between a beam of light made from a large number of identical photons, all moving at the same speed, and a generated radio signal made up of intelligently bunched groupings of any old photons. I'm saying the radio waves use 'photon density' variations, whereas light rays use intrinsic photon properties. You can't realy believe that a constant RF signal lasting ten years is made of one single photon. No, nor do I believe a mono-mode laser running for ten years emits a single photon. Well what's you model for this? So what's the difference George? Are you going to offer any suggestions? None, both consist of a flux of many photons. What's wrong with my above model? Tell me, what is the relationship between an constant RF sine wave and a photon? Same as for a mono-mode laser, bz has told you already so I won't repeat it. BZ knows nothing....but he tries.... Yep, it also mean ADoppler is non-existent for binaries, the light changes to speed c within 4.6 microns of leaving the star's surface ;-) That's c wrt the star George. It is c wrt to the material with which it is interacting to cause the speed change Henry, otherwise you cannot transfer the energy and momentum to maintain conservation. You can't assume it is 'material'. Just call it a 'local EM FoR'. For contact binaries, it appears that such a frame is defined by the barycentre of the pair. However, I agree, it also appears to quite rapidly approach 'c' wrt the BARYCENTRE of the pair in the case of pulsars and short period binaries. This again raises the question, "how and why does unification rate depend on period?" I have answered that before in some detail twice but it is a subtle point and you didn't really follow it. Basically it shows the theory is unlikely to be true because it requires a remarkable coincidence between your pitch factor and the peak orbital acceleration. I don't have a definite view on this yet. De Sitter was wrong.. face it George. He was right, or you wouldn't need extinction. I can live with extinction. De Sitter couldn't. He didn't have to, it had to be invented as a result of his falsification of Ritz's theory. ...and no other experiment refutes the BaTh. Sagnac and Shapiro do. Other factors are involved. As with De Sitter, they falsify BaTh as it stands. If you want to come up with a new alternative then maybe will have other problems, but as it stands at the moment Sagnac and Shapiro both independently falsify BaTh. I have already suggested that BaTh applies 100% only in genuinely empty space. I am also of the opinion that local EM FoRs are present wherever matter or fields exist. It is quite possible that there may be a compromise theory that might explain the intricacies of starlight movement and still accommodate some aspects of Einstein's modified aether theory. I sense that you may be thinking along similar lines. George www.users.bigpond.com/hewn/index.htm Einstein's Relativity - the greatest HOAX since jesus christ's virgin mother. |

On Fri, 4 May 2007 14:16:37 +0100, "George Dishman" http://www.hqrd.hitachi.co.jp/em/doubleslit.cfm Yes I'm familiar with that kind of result. De Broglie waves are quite amazing really. It shows that matter and 'fields' are not very far apart in nature. George, there is nothing here that surprises me. Single photons making up a monochromatic beam should have the same wavelength as the beam itself. The beam is just 'lots of them'. Finally, you have cottoned on to what I have been saying. In the experiment they used a current of 10 electrons per second. Obviously the diffraction pattern is not what you would predict using a frequency of 10Hz in your "grating equation". Each electron behaves entirely independently of the others and the pattern that builds up is controlled by the intrinsic properties of an electron. If you use the interference pattern via Huygens to work out a wavelength, it is the wavelength of an electron that you get, not the 29979245.8m wavelength that corresponds to a frequency of 10Hz. Yes George, that isn't surprising. The thing is diffracting the De Broglie waves of the electrons...whatever they might be. Now try diffracting a 30000 hz radio wave. It WILL use the corresponding wavelength. Yep, exactly the same, but in your other post you claim there should be some energy deposuted from the electron beam at the angle corresponding to 10Hz even though all the electrons go where the De Broglie wavelength says they should. It's all about probability George. You know...you have been teaching me about probability for weeks... Incidentally, did you notice at the top it says "This detector was specially modified for electrons from the photon detector produced by Hamamatsu Photonics (PIAS)." It is just a photomultiplier with the front end photoelectric element removed. It detects single electrons, not single photons... Henry, it_IS_ a PM tube but without the photoelectric emitter on the front which of course ejects one electron per photon. How did you think a PM worked? that's the ultimate aim...not easy to achieve. Most PMs are used simply to amplify very weak light signals.

"Henri Wilson" HW@.... wrote in message Yes it does, that is basic probability theory. Probability is not a cause of anything. It's a result. Nobody said anything about probability being causal. George, like many others, you are completely misinterpreting the role of statistics, which is a science dealing with the outcome of multiple events. Henry, I'm not talking about statistics, I'm talking about probability. There is a subtle distinction. there is. Mathematics, on the other hand, is designed to analyse or predict single events. Maybe you should study probability a bit before trying to discuss it. I have already studied it George. You can say that BEFORE the bullet is fired...because the conditions that cause the bullet to land where it does are random. However, that does not alter the fact that each bullet hits where it does for specific physical reasons that are theoretically capable of being mathematically analysed and explained. Whether or not true randomicity exists is a big question. No, it's not a question at all, it is proven beyond any doubt. You are jumping in too early again George. It IS a big question that includes things like 'free will' if human action is involved.. If I fire a bullet that misses the target, PROBABILITY says, 'that's OK, it is a statistical fact that no matter how good the shooter, occasionally one WILL miss'. However, I say, it missed simply because I didn't aim in the right direction. It is similar to tossing an unbiassed coin, the probability is 50:50 regardless of the outcome of preceding tosses, only the variable is 2D real (location on the target) rather than binary (heads or tails). Yes I know that George. Then why did you say "No it doesn't!!!!!!" ? The bullet is destined to hit exactly where it does from the moment it is fired. Chance doesn't enter into it... Not true I'm afraid, but it doesn't alter the fact that you said "No it doesn't" in one case and "Yes I know that" a few lines later. It's hard to discuss anything when you can't even express a consistent view in a single post. I wasn't refering to the same thing. Mostly, the scatter is dominated by slight variations at the macroscopic level, but a small amount of uncertainty is also an intrinsic property of any individual particle so if you repeat that with electrons there is a lower limit of spread beyond that from the lack of perfect knowledge. Einstein didn't like that but it has been proven experimentally beyond any doubt. Newton's clockwork and fully deterministic universe isn't ours. Nobody has demonstrated that true randomicty exists, at any level. Sorry Henry, your decades out of date again. No. even at the atomic level, this has never been completely resolved. For instance, consider radioactive decay. We know all about its exponential rate. ..but we don't know why each event occurs exactly when it does. Is there a unique physical explanation for each one. Likewise, we don't know why emitted particles move in the directions they do even though the angular distibution is statistical predictable. Yes. A grating deflects an individual photon depending on the colour of that beam, not the rate at which photons arrive. I'm thinking of say a dim red laser with a flux of a few photons per minute. Like the coin tosses, each one is deflected purely on its intrinsic properties. If all the photons are identical, should they all be deflected by the same amount? To within the intrinsic uncertainty of the energy property. That means there is a fundamental lower limit to line width. You can think of that either as the (gaussian) spectrum of the line showing the power in each frequency that you get from a Fourier transform of the received sine wave or as a histogram of the photon energies (which will produce a small spread of deflection angles) or by transforming to the time domain as the phase jitter on the RF sine wave. They are all just different coneptual models of the same feature. If E=h.nu there is no distribution at all. I would like to think that the diffraction angle depends on the actual phase of the photon's INTRINSIC oscillation when it strikes the grating.. Frequency (or equivalently wavelength), not phase. In the case of monochromatic light, the theory says energy is relfected equally at all angles but is reinforced only at one angle. Destructive interference occurs at all other angles thus nullifying energy transfer at those angles. Try to explain THAT with the particle model George. How actually do photon 'particles' cancel each other out? Yes. When it hits a grating each photon deflects depending only on its own properties and not the properties of other photons that arrive some seconds earlier or later. yes. That would have to be right. Excellent. That is a major agreement Henry. not really... Consider microwaves hitting a wire grid. Each photon in the wave is deflected by an angle that depends only on its own properties independent of any others. But there is also a second diffraction based on the microwave 'wavelength'. Same thing. No it isn't. If you modulate a laser beam with a 100000hz signal, you get two entirely different diffraction patterns. Sorry George, I cannot imagine a single photon that is maybe 1 lightsecond in length and expands as a radio signal diverges. Do you think it expands forever? Photons are particles Henry. Look at the example I gave of the sodium doublet. The line width has to be less than 6A while the mean wavelength is 5893A. The Zeeman effect produces individual lines with far smaller spacing. A line of 5893A wavelength and width of 0.003A must contain more than 1.7 million cycles so would be more than 1 light second long in a classical wave model, yet it is absorbed instantly by a single electron in the photo-electric effect. You have never seen zeeman lines from ONE transition. there are always millions involved. Photons are particles and energy is an intrinsic property. The probability of a single photon being measured at some location after deflection from a grating depends on the energy, and the maths that describes that dependence includes a sine function which is related to energy. Planck's constant allows us to express the energy in the classical "frequency" concept which can then be used in the maths. I'm not even going to comment on this type of speculation. I believe the sagnac effect is due to an entirely different factor...such as a local EM frame that behaves like an aether. I don't care what you belive, it is a fact that the measued speed is independent of the speed of the source. Nobody has ever measured OWLS at all George, let alone from a moving source. So don't preach nonsense to me please... I'm starting to think that local EM reference frames are everywhere around us, ...inside accelerators, etc.... The BaTh only holds 100% in truly empty space. Even the IGM isn't "truly empty" so basically you are simply back to LET to explain both the MMX and Sagnac. Indeed it isn't empty, that's why unificatoin occurs....but most of it lies below the WDT, at which level the BaTh operates almost entirely. Come on George, you don't have any kind of model for a photon. You think it's just a couple of sinewaves drawn at right angles on paper. No, I think it is a fundamental particle like an electron which has the property of carrying energy (and others). 'the property of carrying energy' That doesn't really tell us much does it George...hardly a model... I think when the charge is taken to some destination, the car also arrives at the same place. You can't send the car to Boston and have the charge arrive in Cairo which is what you are suggesting. Beyond that discussions of their length are irrelevant, the length has no analog in the photon. How do you know. Because your suggestion is equivalent to saying the heat produced by friction in an ocean wave can be deposited inland. George, you know how water waves can be diffracted, for instance by a row of vertical bars. Yes, and the energy of the waves is then carried in another direction to be deposited where the waves go. If photon are particles that are reflected over 360 degrees from each line, how do you explain all that destructive interference over the 359.9 degrees. Do you really believe that the water molecules that go up and down near the bars are the ones that end up making the diffraction pattern maybe 100 metres away? No Henry, exactly my point. That is what you are telling me, that the grating angle for the wave is not the same as that for the photons composing the wave. Your theory has to rely 100% on the wave model of light to expain gratings. ...and then it fails. My model of photons as independent vibrating quanta explains it all. Henry, I think we have maybe got a handle on this, in your grating equation if you have red laser light arriving at a level of one photon per second, would you use the frequency of the red light or the 1Hz rate of one photon per second to work out the deflection angle. I say it is that of the light regardless of the arrival rate, you are telling me the wave energy goes to one place at an angle determined by the 1Hz figure while the photons themselves go to the location given by the red light frequency. the should be another very weak energy build up where the 1 hz is diffracted. How about modifying your experiment to make the 1 Hz sinusoidal. How about you calculate how much energy BaTh says is in this extra mode you have invented. For a fairly bright source with random arrival times (e.g. a sodium lamp where the photons are emitted thermally) there should be a background continuum under the lines. Make your prediction of that level and then research the literature. I'm too busy...how about YOU do it. The concept matches the data very well. It makes no sense though, how can the energy go anywhere other than where the photons go? Strange things happen. Perhaps, but for your bizarre idea to 'match the data very well' requires _all_ the energy to go where the 1Hz deflection predicts and none to go with the photons. As I said, it makes no sense. How do you explain destructive interference with the particle model George? George www.users.bigpond.com/hewn/index.htm Einstein's Relativity - the greatest HOAX since jesus christ's virgin mother. |

The luminosity variations are purely due to the eclipses so match the velocity knowing your zero phase corresponds to the eclipse centres and then alter the distance. For a small value you will get a match. As you increase the distance and ADoppler starts to contribute, the first consequence will be a shift of phase away from the match. As I said before, you can try changing yaw and eccentricity but I think you'll find it distorts the sine curve too quickly to allow a significant amount of ADoppler. It's OK. It all fits. For contact binaries, K is large enough to make VDoppler dominant for individual photons. The brightness curves are still determined by ADoppler.
