Objectively, your real psyche is in your head and only in your head. It (your psyche) does not exist anywhere else in reality.

I don't need more. My head is in reality. My psyche is in my head, so my psyche is in reality.

You have gone away from answering what reality is in your view. Physics is a very different science. For example, quantum mechanics is very different from classical mechanics, and hydrodynamics from the kinematics of solids.

That is, in probability theory it is appropriate to say "expectation", and in statistics "mean", and it is undesirable to confuse them, otherwise it becomes bad for specialists from this field? Right?

These are fundamentally different concepts, look at the definitions, the first refers to abstraction (random value), the second - to the processing of empirical data.

Traders do not use probability theory in their practice.
Inaccuracy in terms generates errors in reasoning (I did not invent it).
But if you really want to, you can call an aeroplane an aeroplane and a car a shaitan-machine).

1. What happens to reality if you subtract your psyche from it? Maybe the acceleration of free fall (or other physical constant) will change?

2. Quantum mechanics is not {no different} from classical mechanics. Quantum mechanics has a different object of study) Similarly with fluid dynamics. These are branches of physics, intertwining and diverging...

I came up with a definition: Reality is the totality of material bodies remaining after subtracting your psyche from reality)

So you don't consider yourself endowed with psyche - just a material body?

You are very much mistaken about this. Start with the definition of quantum mechanics in Wikipedia, + thousands of textbooks on quantum mechanics + the works of its founders - Planck, Schrödinger, Heisenberg, Dirac, Pauli, and others.

... In general, are you sure you understand complex numbers correctly?

Enough to know that the square of a complex number is usually not equal to the square of its modulus.

i^2 = -1, but |i|^2 = 1.

(1+i)^2 = 2i, but |1+i|^2= 2

The problem is that the mean can always be calculated, but it is not always an estimate for the expectation.

It doesn't follow from my post.

Saying that quantum mechanics is different from classical mechanics is trivial. Yes, it is different, it is obvious.
These branches of physics have different objects of study, respectively different methods...
A hammer is different from a screwdriver. Yes, well ... ?

(1+i)^2 = 2i, but |1+i|^2= 2

I see. Complex numbers aren't the hard part here.
