Can many-valued logic help to comprehend quantum phenomena?
... The first attempts to explain numerous paradoxes of quantum mechanics on the basis of many-valued logic were made by Polish logician Zygmunt Zawirski in the early Thirties of the XX Century. Zawirski in his papers published in 1931 [24] and in 1932 [25] argued that Bohr’s complementarity could be co ...
