It seems that periodically there is evidence showing that the universe is this or that and yet nothing is and it will never be concrete because it's impossible to find the root of the universe. I see it as a more philosophical question. I think we should be more focused on exploring the universe, not understanding it.
Really enjoyed the read! Two minor things I found: downgrade(&self) should be downgrade(self), and rw2 and rw3 have TCell parameters, should these not be QCells?
Maybe it's time for a global reform on schools' approach. I see more and more that children aren't willing to attend school. And I think that's because the approach is the same in the past 30-40 years, at least in my country, Nothing changes, the literature is the same, the teaching methods are the same. I feel that there's a need of change.
