Localization, interaction and the modern interpretation(s) of quantum mechanics
... In recent years, our continued lack of progress in finding a convincing theory beyond the standard model, one which would unify gravity and quantum physics, has led many physicists to speculate that it may be precisely an incomplete understanding of quantum physics which is a root cause of the probl ...

Brief introduction to quantum mechanics
... „There was a time when newspapers said that only twelve men understood the theory of relativity. I do not believe that there ever was such a time... On the other hand, I think it is safe to say that no one understands quantum mechanics“ R.P. Feynman The Character of Physical Law (1967) ...

Under suitable conditions, she turned out to be visible to the naked eye.. It used to be claimed that no-one could ever see an atom with their naked eye ...
