Confirmation of Aether drift direction from COBE CMBR data/DaytonMiller experiments

So it is a mathematical concept that knocks electrons out in the photoelectric effect? .... So what I am saying is: EM radiation hitting a material will _only_ knock loose and electron when the De Broglie frequency of the electron in its orbit matches the frequency of the incoming radiation. That would produce a resonance, a spectral line. The whole point of the photoelectric effect is that the kinetic energy of the released electron is proportional to the frequency of the photon minus the work function, the energy needed to free the electron from the surface, over a wide range of frequencies.

wrote in : http://groups.google.com/group/sci.p...025a064f e7cd We see a _minimum_ frequency required as is observed with photo electric effect. So in short, the _emission_ is quantisized, and that is about all. Of course QM explains the photoelectric effect and in QM the photon is a QM state which is neither particle or wave. However the point is sometimes is acts like a particle (and the fact the photoelectric effect is explained by a simple particle model proves this) and sometimes like a wave and may from some recent evidence even both at the same time. But saying it is just a mathematical concept is going way too far IMHO. I am not sure. It was Planck himself who suggested to Einstein that:" 'Look more at the 'photon' in the context of EM waves interacting with matter.', In that sense it _is_ a mathematical concept, you can assign some energy to 'photon', or simply say: energy of photon if frequency x Planck's constant. As 'f' can be freely chosen, that makes 'photon' just that product. You can assign mass to 'a particle', but not to photon. In no other context than at the border of (heaven and hell or) EM waves and matter _should_ that idea of photon be used or even be of any significance. (I was just kidding about that heaven and hell part). You often read 'this new detector detects a single photon', well, maybe maybe not, but without specifying in a lot more detail it makes no sense whatsoever. I have heard (not read) scientist make claims 'hey, this detector just detected a photon', while from an electronic POV I was 100% sure it just happened to trigger on a sufficient amount of EM waves to release that electron, that then in the photo-multiplier was accelerated and knocked out more electrons, so it resulted in a big current after x dynodes so it could be amplified and that signal was enough above noise and threshold to 'count'. If you look a bit closer at that first target in the photo-multiplier (where the light hits the metal) then there are plenty other factors, thermal motion for example, that will make some atoms more 'ready to give up an electron' then others. The EM energy however works on all these atoms, the one that actually gave up the electron causes the 'detection', you know little about the energy part landing on all the other atoms. In fact the detector sensitivity changes of very short time intervals... You cannot state _any_ energy level that _will_ be a minimum, and at lower levels you will not be able to tell 'photon' from 'noise' if it was truly a single event, and not some synchronous experiment. If fact this predicts one should be able to improve detection efficiency by pre-lighting the detector with a sine wave of a frequency close to the frequency of the EM waves received, as that will make electron orbits more unstable, and make it easier for incoming EM radiation to trigger the release of an electron (as in link I have mentioned above). Since the EM 'bias' wave is a known, this could be processed out. It is an old technique to get linearity form a non-linear medium, In fact the 'RF bias' was used in analog (audio) magnetic tape recording to allow audio to be distortion free recorded on non-linear media (non linear because of the BH curve of the magnetic material used). Best noise performance is obtained by a bias as symmetrical as possible.... With those things in mind any quantisation in a 'photon' detector goes out of the window. And so does the last straw of 'photon particle'. |

To make the matter worse, Cahill "forgets" that the experiment he's suggesting has already been run about 30 yeras ago. Then, Consoli quotes Cahill, what a commedy. Thanks Rambus. In fact I wasn't aware of the Consoli work either. Do you know of a good reference for describing correctly the speed of light in a moving refractive medium, in terms of the MMX and related? I haven't seen a recent one and was thinking of writing it up as a review in light of recent Cahill / Consoli publicity. No, I don't know of any but it is easy to write. |

Sure there is: any real signal would have a sinusoidal variation with orientation with period 1/2 turn. A quick glance at the MMX data clearly shows such a sinusoidal variation. Without an error analysis one does not know if it is significant or not; it isn't -- see Appendix I of http://arxiv.org/abs/physics/0608238 . Tom Roberts |

Cahill botched his equations (so did Consoli) 2. Yes, you are right, the effect is insinificant in the case of MMX because L1-L2 is nearly zero and the runs are short , so delta_v is insignificant 3. The effect is no longer insignificant in the case of Kennedy Thorndike because L1-L20 and delta_v is no longer negligible due to the long run (190 days): http://qom.physik.hu-berlin.de/research_kt.htm. So, all three of us are correct, we are just talking about different issues. |
