Inside the Camera Obscura You can either imagine yourself very small, or the camera obscura very large. Whatever suits you. You are standing with your...

That is the whole issue right here. Cosmology is metaphysics for scientists. But then again, another general objection, a show of loyalty and no attem...

Certainly. And I am curious about how you look at it.

Not interested in double slit experiment? Newton rings? Interference? Optics? Other problems in Physics? No problem. Just don't waste my time and I wo...

I would kindly suggest you stop reading my threads since they only seem to aggravate you.

I know what is said about polarization. It just does not convince me.

I see you fall back on the same general strategy I have been facing until now. Let us say I am wrong about my views considering Relativity and Quantum...

Posty McCarthy?

who u callin' kids, girl? Dobe to you too!

I'll keep my eyes open and my lips ready. edit: my ears too.

guy says to hero de Niro: it is not bribery, I am now free and give you this money belt freely. - how much is in there? - in the neighborhood of $100....

nice talent.

I heard mine about 40 years ago. Your version must be much younger?

Where is Poisson when you need him? Poisson, an ardent supporter of Newton's corpuscular theory, had calculated that Fresnel's theory implied that the...

I pulled the door ajar to this snake pit, so I should not be surprised if somebody pulled it all open. Here is what I have to say in a nutshell. 1) I ...

yeah, I know what you mean. Maybe it should go like this: Camus: to be is to do. Sartre: to do is to be Sinatra: do be do be do

Sartre: to be is to do. Camus: to do is to be Sinatra: do be do be do

good answer. I don't feel like going into that snake pit either.

Yes, that is certainly a real danger. The problem is that scientists are usually worse philosophers than philosophers are bad scientists. That's what ...

A Real Life Approach (2) There is something very interesting in the preceding, but also in the following images. Objects seem to react differently fro...

Of course, if it were merely a technical question. But then, how would scientists make the distinction between those "sound" waves and other kinds of ...

A Real Life Approach Double slit experiments are usually presented in a very abstract manner. The light source must be monochromatic, and it is at the...

I do not mean sound specifically. I assume that we would not hear anything. But would something like the LIGO detector notice anything going on in spa...

but before that, nothing?

The point is that two objects collide in space where there is no medium to propagate sound waves to our ears. Maybe your are right, and only heat and ...

Wave length, Distance and Interference The principle of interference, and wave length, depends on the actual distance a wave or a ray is supposed to t...

Vertical Slice I have used a simple application any Windows user have at his/her disposition, Paint. What I have done is take one of the pictures of t...

Finally! The Real Double Slit Experiment! I am sorry it took so long, but I just got the slide in the mail this afternoon. It concerns a slide (50mm/5...

good luck and so be it.

I couldn't agree with you more. But you should do something about it if you really believe that the forum is in any danger of being perverted.

I am curious as to how you intend to counter my malevolent influence.

I would be, to name but a few themes, very interested in your views about the double slit effect, interference and Newton rings. I am not inviting you...

I suggest you open threads where you disassemble "wrong" ideas about scientific issues. That would be a positive contribution to this forum, much more...

I think T Clark, that you belong with the so-called philosophers of the middle ages that considered everything that Aristotle said a word of truth. Ma...

You mean: "Stop trying to hit me and hit me!"?

Distance, Object Size and Light I have already discussed of the singular fact that objects become smaller with distance. For that I got treated to an ...

White Light and Interference (2) This is how the same picture looks like when a red (dark orange) filter is placed in front of the torch. Except for t...

White Light and Interference I find the following picture quite intriguing, especially when you consider how the camera reacted. Instead of a laser pe...

Interference and Newton Rings Allow me to start with an image already displayed, an open camera body, no lens, and a laser pen directed at the center,...

Thank you for the tip. I will try and put it into practice all the time.

A Youtube clip, and there are many, shows how much the use of an interferometer depends on the beliefs of the observer. It is like pointing at a Santa...

Please understand my reaction. I consider my threads as a work in progress, but only if I can find my own posts back and relevant comments and objecti...

Maybe you guys could start a thread about probability and determinism. It won't be the first, and it doesn't need to be the last.

Please remember that this thread is about a light phenomenon, and not about consciousness. That would also be my plea to Rich, not to drown this threa...

I would be inclined to agree with you with the following distinction: there is nothing probabilistic about material processes, only about our knowledg...

Let us say that, if there is something like a photon, I am convinced it goes either through one slit or the other. https://philpapers.org/post/23274

I remain firmly deterministic. Call it a metaphysical prejudice.
