He has a Ph.D. in Physics.
There are more contradictions in physics than in religion.
You wrote quite a lot in response to the first question, but you still didn't answer it.
What about the other 4 questions:
2) The lift force, within an acceptable margin of error, corresponds to theoretical calculations. I have done such calculations myself, I know.
3) It took me a long time to understand what "Hydro-phonics" was. What do you think Google search gave me? That's right, a podium. Finally, I realized: "hydroponics"! But in hydroponics, the plant receives minerals from the water, which is specially saturated with these minerals. Everything else, as you know, it takes from the air. What do the elements' nuclei have to do with it? Nothing, gentlemen, nothing. And in general, this is not physics, but agriculture.
4) Give an example of at least one such mollusk that definitely receives calcium and everything else it needs, not from the environment. And for now, let's, like Stanislavsky, shout "I don't believe it!"
5) It's possible. It was explained to everyone in school.
