Ed,
..Are they actually trying to aim a single photon at the slit? ..
That is what I want to ascertain. that in itself shouldn't be a problem. But if they are firing at the area between the two slits, which will be orders of magnitude wider than a photon, the question becomes 'why does any photon go through either slit ?' Surely they should all hit the area in between the slits.'
Here is another for you.
If you look through a glass sphere at a scene, you see the scene, but inverted.
No problem with that.
But this implies that right at the centre of the sphere is a very small area where the image inverts, and that at that point it is neither up or down. (a bit like the Grand Old Duke of York's men.)
Also, all the information contained in the image is in there in that microscopic point. And it is somehow inverted.
Makes the old brain ache a bit.

INT21 Hal, I'm not sure they are aiming single photons. How would they do that? You can do the slit experiment at home using a laser pointer and CD (look it up). The sphere thing I think you are looking at the tree and not the forest. Are you saying the resultant view could be either inverted or not? I doubt there have ever been any observations supporting that. I generally don't think about such things so I could be wrong.

No, I'm not going all quantum on you.
The image is always inverted. It has to be. Basic optics.
My point was that, when you look at a scene you are taking in a lot of data. If you look at the same scene through a glass sphere the image is inverted. But you are seeing the same image and thus processing the same date.
But in the process of inverting the image in the sphere all the incoming data changes orientation in the very centre of the sphere. Where it will be a very small point.
As for the double slit.
Yes, they do fire single photons at the screen. There are a few documentaries out there about it. I don't know how they generate the single photon pulse.
If a wave of light is shone on the screen the interference pattern is obviously similar to water passing through the slits. But a single photon ?
Is a single photon classed as a particle or a wave ? or both.
Using a laser is interesting. Have you tried using one as a very high power microscope ?
Maybe Cliff can jump in here.

Maybe cliff should, but I thought he was more Astro than Quantum. HAL Is it "this or is it that"
what is under our hat sorry could not help myself giggle
Is it possible our observations
have electromagnetic influence ? Light can be bent from magnetic force, YES?
case in point how did this thread move from prox B to the light photon?
IT WAS THOUGHT AND OBSERVATION Maybe the Bonehead should speak now. MKW

MOKSHA, You've invoked Bonehead. Now we are in for it. HAL
