The submersible is either on the surface or on the bottom. If it is on the bottom, it will perhaps never be found. The search efforts will quickly stop after the rescue will turn to recovery. (MHO.)

This is interesting question.

The OP did not say anything about object/image distance. Rather about mirror/reflection size.

This is what I've found so far on this question: (What are submersibles, how do they communicate? (rte.ie))

You do not read it right. And I am tired of trying to explain it. You should focus on the reasoning rather than on the words. It is a matter of energy conservation, not of interpretation of the words. Good luck!

Only a very small slice of reality is around us in daily life.

I understand that you in fact mean "arbitrary."

Potential? It is used in engineering all the time! What conditions?

Units need to be compatible. They don't need to be the same. Compatible does not mean equal.

How do you know that this mathematical equation does not represent physical properties?

Ever heard of F=ma? m is in kg, a is in m/s2. Different units multiply just fine.

It looks as I misused the term "flow regime". Let's see what we agree on. When a fluid freely flows in a tube, its pressure on the tube walls in areas with a larger cross-section is higher and its velocity there is slower than its pressure and velocity in areas with a smaller cross-section. However, the statement, "when there is movement of a fluid within a solid body there is less pressure on every point of the surface of the solid body from the fluid" is incorrect. Less than what? Where is a tube with different cross-sections?

Any ideas on how to do this?

What makes you think that Turing Machine cannot be applied to real world, cannot learn from data, adapt and improve?

Yes, they are so stupid now that it is not difficult to make them smarter.

This is correct. This does not follow from the preceding paragraph. In the preceding paragraph, the pressure in two points of the same flow is compared. In the latter, two different flow regimes are compared.

AFAIK, the fine structure constant is one of about two dozen numbers that need to be measured experimentally and plugged in the SM by hand because there is no known way to derive them from first principles. When the founders of QM called it "the most fundamental unsolved problem in physics," about 100 years ago, there were not that many of such numbers and many other unsolved problems, e.g., quantum gravity, dark energy, etc., were not yet known or formulated. I don't think it is generally considered as such today.

Why compare everyday language with math. What we discuss in above is to compare math with logic. OK, compare with logic. What does it mean in logic?

And the answer is....

Here is a mathematical statement: It has a profound meaning in math. What does it mean in English or Chinese?

Singularity is a consequence of GR. Gravitational wave is a consequence of GR. In GR, singularity is NOT a gravitational wave. If you want to consider a singularity as a gravitational wave, then either the singularity or the gravitational wave (or both) should be NOT what they are in GR, but something else. What are they?

It's not even why they think what they think. We don't know what they think. We only might discuss why they said what they said.

OK, this looks like the Fourier series I've mentioned. Any wave can be decomposed into a sum of weighted sinusoidal waves. Each component wave behaves independently, and the resulting wave behaves as their sum. The component waves do not affect each other.

No, you didn't upset me. By vague I mean that answers depend on what you refer to as wave and as wave carrying wave.

It doesn't make sense to go on with this vague language. The only way to ask and to answer meaningfully is to use mathematics. Check, e.g., Fourier series.
