We moved from the subatomic realm to the atomic world, representing our physical environment, known as the macrocosmic world.
The periodic table:
We are well-versed in these elements, so there is no need for further elaboration, as they are part of our everyday lives.
We have gained insights into interpreting certain peculiarities, such as the Lanthanides, and the range of elements extends to over 100. It seems that heavier nuclei have difficulty maintaining their integrity when subjected to high rotation in three axes. The Lanthanides may provide reinforcement by adding extra neutrons, while the other heavy elements require relatively few neutrons to trigger degradation.
There is much more to study, provided there is scientific interest in pursuing it.
