1.0.: My answer to Feynman's question

Dr. R. P. Feynman (one of the founders of quantum electrodynamics) said the following wise words: $( \sharp_1 )$ and $( \sharp_2 )$.

 $(\sharp_1)$: There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time. There might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot of people understood the theory of relativity in some way or other, certainly more than twelve. On the other hand, I think I can safely say that nobody understands quantum mechanics. $(\sharp_2)$: We have always had a great deal of difficulty understanding the world view that quantum mechanics represents.$\cdots \cdots$ I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem.
In this lecture, I will answer Feynman's question ($\sharp_1$) and ($\sharp_2$) as follows.
 $(\flat)$: I am sure there's no real problem. Therefore, since there is no problem that should be understood, it is a matter of course that nobody understands quantum mechanics. That is, since there's no problem, what we can do is only "Shut up and calculate!" .

This answer may not be uniquely determined, however, I am convinced that the above ($\flat$) is one of the best answers to Feynman's question ($\sharp_1$) and ($\sharp_2$).

The purpose of this lecture is to explain the answer ($\flat$). That is, I show:
If we start from the answer ($\flat$), we can double the scope of quantum mechanics.
And further, I assert that
Metaphysics ( called "quantum language") is located at the center of science.
That is, \begin{align} & \mbox{To do science} \\ \doteqdot & \mbox{To describe phenomena by quantum language} \end{align} In this lecture, I will show the above.
