<div>Hi Chip & all:</div>
<div> </div>
<div>Abandoning alchemie and similar efforts to do the impossible are not equivalent to "giving up." Of course, observe what can be observed. But then do not attribute to what has in fact been observed to imaginary entities erroniously attributed to what was observed. Here, one thing is certain, E&M waves, photon streams, and the like have not been and cannot be observed. Just charged particle motion has benn observed. All the rest is concocted dogma.</div>

<p class="MsoNormal"><span style="color: black;">Yes. But we can find out a tremendous amount by observing what we can. The specific behaviors caused by various circumstances tell us much more than just the fact that charges move masses. What we can observe yields many clues because it discloses certain rules and patterns to the reactions. No need to give up just because our ability to sense these things is limited. </span></p>

Be definition a two-gender charateristic of particles with mass to be attacted given similar genders, and repelled given dissimilar genders. (Note: gender is determined in terms of what they do.) Thus, the attraction or repelling is defined in terms of the motion of the charge-carrying masses. In other words there is nothing to be said about the whole matter except what the "charged" masses do dynamically. This is exactly what happens in practice. Currents are manipulated in sending antennes and measured as photocurrents in receiving antennas. This means that, nothing can be said about the interaction (attracting or repelling) but only about the motion of the masses; all the rest is inferance. Including waves, photons, magic bullets, whatever! Logically this inference is indeterminable separate from the motion of the only observable, the masses. Might as well say: "God does it; basta!" Maybe God is a photon!!</span></p>

<p class="MsoNormal" style="background: white;"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">In this paper is presented a simple alternative model of the dual nature of light, based on the deliberate inversion of the original statement from P.

</blockquote>
<p class="MsoNormal" style="background: white;"><span style="font-size: 9.0pt;font-family: Verdana , sans-serif;">While it makes what I feel is a needed refinement of Chandra/s Non-Interference of Waves position, it perhaps still misses something that Dirac might not have been aware of - the existence of identical photons. Your use of "different" <u>could</u> preclude "identical"; however, the language is ambiguous and it could also include separate, but identical, photons.<br/>
<br/>
I would contend that identical photons (and perhaps the recently-produced, single-wavelength, photons) could interact with one another.</span></p>

<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">Hello Everybody: Here is a potentially new “thread” for debate for our community.</span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">“Can a single indivisible photon interfere?”</span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">My answer is a strong “No”.</span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;"> </span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">I just presented this paper at the OSA Annual meeting last week, held at Washington, DC. It was well accepted by many.</span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">It is only an 11-slide presentation. However, it experimentally demonstrates that, for Superposition Effect to emerge, we must have the simultaneous presence of two physical signals carrying two physically different phase information incident on the opposite sides of the beam-combiner of a two-beam Mach-Zehnder interferometer. The superposition effect emerges as purely a classical effect facilitated by the dielectric boundary of the beam combiner (classical light-matter interaction; no QM). The energies in the two superposed beams can have any value, no lower limit like “h-nu”. Thus, single photon interference is causally and physically an untenable logic, in my view point.</span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;"> </span></p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">The experiment also underscores that the postulate of the “Wave-particle duality”, is completely unnecessary for EM waves. In fact, the Copenhagen Interpretation becomes more logical and causal without this postulate. The QM formulation is essentially correct. We do not need to degrade it by imposing non-causal postulates.</span></p>
<p class="MsoNormal" style="background: white;"> </p>
<p class="MsoNormal" style="background: white;"><span style="font-size: 14.0pt;">In the past, I have also proposed an experiment to validate that for “particle interference”, we also need pairs of out-of-phase particles to nullify the stimulation of the detector molecule to generate “dark fringes”.</span></p>
