X-Message-Number: 4445 Date: 24 May 95 14:59:29 EDT From: yvan Bozzonetti <> Subject: SCI.CRYONICS: Back to BONZO (BOson New ZOne). Do you recall the flame war some months ago about photons with low interactions and long range tunnel effect ? There has been a private exchange with B. Wowk on the subject until December 94. In it, he accepted to see photons as the convolution product of an infinite sine wave and a door function, limitting it at a finite length ( a shift from its first public position ). Then he requested me about reference on nonlinear systems, I gave him the source book reference for time dependant atom structure and interaction used in fusion device calculation and get no more answer. So, I start again on the subject in the public domain. (I am sorry for some reader to do so, my motive is in the feeling about the sensivity of that domain for brain reader systems : Yes, a forbiden subject on this list ! So, I'll don't report here on my talk to build a first step system-). Back to photons: First, there is a shocking effect with photons : From Special Relativity, their proper time is always zero in duration. In their rest frame, time is infinitely expanded and what can take billions of years for us takes only one instant for the photon. Assume you have a source, a medium to travel in and a detector. In our time, emision at the source comes first, then there is the travel and at the end, a hit on the detector. For photons, all three things come in the same instant : So, if you take some action at the detector level, you can alter the photon behavior in the travel part, a process looking at first as time travel because the photon seems to know in advance (in our time ! ) what it will encounter at the detector. To put that shortly, a "special" (nonlinear) detector must produces special propagation properties, that is what I talked about some months ago, stressing mostly conditions at emission and may be not sufficiently at reception. B. Wowk has accepted the information theory picture of the photon where a wave is convolved with a door function (asquare wave in the simplest picture). If our exchange could have extended, my next argument would have been : There is one sine wave and three, not one, door functions : One at emission, one for the travel and one for the receptor. If you want to see nonlinear effects in the propagation domain, you have to use nonlinear systems at both ends : In the source and the detector. If there is one linear element in the set, it will erase everything and you get back to tooth radiography technology. This is because one linear element turns the single photon proper time instant linear. To understand what can happen, it would be useful to translate mathematical equations into pictures. Not everybody understand a convolution product, least so the effect of two or more such products. Assume a system in a coal mine is loading continuously a set of car with coal. This is the infinite sine wave we start with, each car is put for a wavelength. Now, to move coal at a distant location, the car line must be broken into finite car sets or trains, this is the first convolution product. Now, if you want to know how much coal is in each car, you must take each car separately to weight it. This "linearising" second convolution destroys any memory of the train length. If you are interested in trains, not individual cars, no linear systems must be introduced in the chain of events. This is obvious for trains, why not for photons ? A snail mail physicist said me a long coherence length photon would produce a continuous jump between states in the detector without much effect on absorption coefficients. This is precisely what is pictured in the weighting car process. Another correspondant, a former space program Director, put it on more practical ground : "What is the point to look at long coherence length if there is no detectors able to handle them ? ". ( Yes, as said above, we need nonlinear detectors). To summarize : Special relativity constrains us to use both, nonlinear sources and detectors if we want to se nonlinear propagation effects. If there is one linear process in the chain, B. Wowk arguments are good, if there is a full nonlinear chain of elements, new effects enter into play. I'll get back to them in more details in comming BONZO messages. Yvan Bozzonetti. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=4445
