Nuclear Physics works by the laws of ethics
According to current Nuclear Physics, the radioactive nuclei should have to emit two deuterons 1H2. By this way it would obey to the principle of least action.
However the nuclei emit one particle 2He4, instead of two particles 1H2. So, the current Nuclear Physics is wrong, because as it violates the principle of least action of course something is wrong with the theory.
By emitting two 1H2, energetically the result would be the same compared with the emission of one 2He4. And the emission of two 1H2 is according to the principle of least action, because it's easier to emit two 1H2 than to emit one 2He4.
What say Eisberg and Resnick ?
They claim that a radioactive nucleus emits one 2He4 because it's more favorable for the nucleus, from the energetic viewpoint.
This is not true, because from the emission of two 1H2 the profit in energy is the same, and the emission of two 1H2 is easier.
But from what say Eisberg and Resnick we conclude that the nuclei work by the laws of ethics.
Indeed, according to Nuclear Physics, the decay occurs as the nucleus should be thinking, and saying to himself:
"Oh, I know that by emitting one 2He4 I am violation a fundamental principle of Nature: the principle of least action.
However, I prefer to violate such principle of Nature, because the emission of one particle 2He4 is more favorable for the nucleus. After all, I must to cooperate with the nucleus".
Therefore, instead of working by the physical laws of Nature, actually Nuclear Physics works by the laws of ethics.
