I am afraid I do not share the metaphysics of the Copenhagen school. I do not believe the particle is in anyway affected by mere observation, and I ce...

Agreed. There is always a matter of interpretation. The question is whether the phenomenon in question is defined by the instrument or the other way a...

Constructive and Destructive Interference 1) One of the main arguments in favor of constructive and destructive interference is presented in a very un...

Multiple Pinhole Cameras If you google this expression, or search it on Youtube, you will find and see many examples of such an original device. I wou...

Thank you for your advice.

Well, I suppose we have come to what really separates us. Different metaphysical models. See, I do not believe that photons, whatever they are, go on ...

We seem to have left the realm of Physics altogether.

I will ignore my mistake for now, and plod further. This is a moment of great mystery for me, photons that go on indefinitely unless they are stopped....

That is the explanation I expected. There are some things which I would like you to explain to me. I know it sounds rather simple, but we are trying t...

I meant simply an electric torch to light the way through the dark wood.

You are walking with a friend at night through a wood, she is holding a torch and you follow her a little from behind. She is directing the torch forw...

I should have used the term wave instead of beam. After all, a beam is something we perceive, but the wave is what is supposed to explain the mechanic...

I will make another effort, but this time I will refrain from any controversial claim and simply express what I understood from the objections. 1) pho...

I've had it with you. I am not responding to anymore of your posts. You are just too dishonest. Read again what I said about the speed of light. End o...

The fact that we see a light beam that is directed away from us , should be a hint that we need something else but photons to explain vision. Unless y...

It is funny that suddenly the number of photons has become insurmountable, when all scientific experiments concerning photons, among those the photoel...

You are now being dishonest. A handful of photons is not a scientific term because the post is not a scientific formula but expressing a concept. Take...

The problem with such a picture is that even those weak photons are visible from all directions. Allow me this link to something I wrote almost a year...

This is of course not entirely correct. Within the same distance I will become visible to you at some point if the intensity of the light is raised hi...

The point is that however much light falls on you, it just never seems to be enough to make me visible to you, while you remain visible to me however ...

You are a real live textbook. So, let me take advantage of it. You reflect enough light back to me that I can see you, but not enough that you can see...

very nice drawings. That is why it took you so long to answer. The distinction between visible and invisible light is a nice touch. But tell me, when ...

I am glad you are back, let me understand it straight. If I am standing in darkness while you are standing somewhere illuminated, I cannot see you bec...

Why is everybody so afraid? I find it really curious that some issues are systematically ignored when it comes to the theory of light, while at the sa...

can't win'em all edit: I would like to thank you though for the opportunity you offered me to clarify some points. You did not make me change my mind,...

I am afraid we cannot convince each other.

What you do not seem to accept is that those differences are based on observations. In other words on the fact that observers (or devices) are able to...

I find it curious that you do not see the contradiction. Don't you find it strange that one moment Io is there and the other it is not? Isn't that wha...

Simulations are very often, as in this case a pedagogical instrument. Once again, I do not doubt that the speed of light is finite, even though I doub...

It is in fact quite simple. If you see it happening, then it is not a matter of "snapshot". Let us say you are looking at Jupiter and you see the moon...

I have no interest in explaining my position over and over again anytime someone new comes in.

I am sorry. I am out of patience. Nothing personal.

How are lasers made? Look at this image and tell me what it reminds you of. https://youtu.be/qkQo6gig3tQ?t=55

Destructive Interference? Look at the image on the screen that the M.I.T professor uses as a proof of destructive interference. https://youtu.be/RRi4d...

Yes, that is right. His argument is, as far as I can see, wrong. That does not mean that he is wrong about the idea of light speed being finite. I hop...

I expect people to read carefully before they comment. And you are not doing that.

Why is everybody so keen in making me say that the speed of light is infinite? Did you even read what I wrote? It is about perception times!

I am afraid you are wrong. Romer's calculations were based on the average of observations made over 10 years! So it was a matter or seconds, or even l...

Here is an intermediary phase. This picture has been taken with 1/500s /uploads/resized/files/kw/n6d6ui5ljar20phx.jpg And this one with 1/2000s. /uplo...

Faster than the speed of light? My theory, or rather my raw intuition, will be easily falsifiable. Imagine two observers, one near Earth, the other on...

3. We disagree on the differences and similarities between resolution and parallax, but we agree on the fact that resolution is involved when looking ...

You interpret "snap shot" as meaning a discontinuous flow of photons. I agree with you that it is highly unlikely. But then I do not think we see obje...

This is a photograph taken with the bare body of a digital camera on a tripod. A red laser pen is directed into the camera, very close to the center, ...

This has also been asked by VagabondSpectre. Maybe it seems obvious only to me, but greater distance blur objects, or points together. A simple exampl...

Thank you for making the effort of stating more clearly your objections. 1. You might be right concerning the fact that with current telescopes we can...

that is exactly what my pictures also show. Regarding my arguments, no I will not repeat them. I will wait for your objections that have to be about w...

I will clarify that nowhere do I claim that the speed of light is infinite. In fact I do not believe that is the case. if you had read what I wrote on...

The setting is exactly as I described it. A camera body to which were attached extension rings, empty tubes, usually to allow getting closer to the ob...

1. The pinhole lens has a Nikon fitting but is not made by Nikon. 2. Your assumption of diffraction is not reasonable, Why should a collimated beam di...

You seem to agree with me, so I am not sure what I should say. maybe you are right and what the admiral sees is such a tiny speck on his officer's ret...
