Undecidability in quantum mechanics
The logical structure of quantum mechanics is investigated. After some remarks on formal systems and interpretations, it is shown that Bohr’s complementarity can be seen as an undecidable proposition. The flowing of the time prevents the birth of contradictions in nature, because it poses a cut between two different, but complementary aspects of the reality.
