| About the photon spreading ... In QED they talk about the probability
| wave pattern. I am trying to find for certain by means of an
| experiment if the single photon spreads out in space. What do I mean
| by spread out in space? Imagine a balloon collapsing under water in
| the ocean or an explosion. This causes waves in the 3D space. In
| radio waves, we can measure the waves by electromagnetic forces. In
| electronics they call this induced voltage. Anyhow, the radio wave
| also spreads out in space. The beamwidth depends on the antenna shape.
| So radio waves also spread out in space. So take a simple radio
| station dipole tower. I walk around the tower, 360 degrees, and pick
| up the radio waves with my radio. Now QM claims that even radio waves
| consist of many photons. What if the radio stations signal was so weak
| that only one photon per second was emitted? Are you saying that each
| photon would be emitted from the tower like bullets in a random
| direction each time? So a photon could be emitted at 10 degrees, then
| the next at possibly 140 degrees, then 87 degrees, etc. Am I
| describing this correctly? So then me and my hand radio would not
| always be in the path of the photon, correct?

| Doesn't that suggest that the x-ray photon is wider and/or taller than
| the grid spacing? I mean, if the grid spacing / air-space is say 10mm,
| and the wire diameter was 1mm and if the x-ray photon is much smaller,
| then wouldn't the x-ray fly right through the grid without hitting the
| wire most of the time? I don't know ... this is one of my major
| questions. Presently I agree with you, that in such a test the x-ray
| would hit the wire grid most of the time. If the width and height of a
| single x-ray photon remained at its length, the wavelength, then the
| x-ray photon would miss the wire grid almost every time. I think
| professor Richard A. Muller at Berkeley made it clear to me that a
| single photon spreads out as it traverses. I don't think the single
| photon's width is the same as a wavelength. I would like to do this
| test one day but surely someone has already performed this test. What
| I am suggesting is not the interference experiments.
|
| Here is another example ->
| Take a sensitive photon detector. Place a photon emitter roughly 1
| meter away from the photon detector. Emit a photon. Record if the
| detector saw the photon. Repeat the test several times. Assuming our
| detector is fully capable of detecting the photon nearly 100% of the
| time, then how often will the detector see the photon?
|
| Perhaps this is what I am being told here. The photon has a
| probability wave pattern. In other words, until the photon is
| detected, it is assumed to be in all possible locations within a
| distance region relative to the time it left. Therefore, the photon
| would hit the wire regardless of the spacing and wire diameter. Then,
| once the photon hit and was absorbed by the wire, then the entire wave
| would collapse, and therefore only one part of the wire grid dish would
| get hit by the x-ray photon.

In an article New scientist 15 march 2005 a new double slit experiment is
described (not all of the interpretation I agree with BTW) but the article
describes an ultra short Laser Pulses as electric fields and talks about
negative and positive peak's. My picture of photons is as similar to the
electric field produced by an AM radio transmitter producing a constant
tone. The modulation envelope being the size wavelength of a photon and the
carrier wave the frequency of the photon. My web site has a bit more detail
and I am trying to assemble more factual data not based on the quantum and
the EB field mantra.

Maybe updates. The turnips and leeks are coming up nicely. Ooh ah.{:-)
