intuitionistic math can help in quantum physics?

I made a potentially-related observation in connection with "proofs of 
life": classical reasoning is too permissive for reductionist subject 

Reductionist here means that two distinct languages are used on each 
their side of the consequence relation, and that the language of 
premises ("on the left") pertains to more fundamental concepts than the 
language of consequences ("on the right").

Classical logic admits excluded middle (specifically, stability, i.e. 
"excluded middle on variables"), meaning that higher-level conclusions 
can be reached that are not anchored in specific lower-level facts.

NB1 The above seems to point to minimal logic as the proper setting for 
reductionist science. However, intuitionistic logic can be obtained by 
admitting the law of weak excluded middle (and, specifically, weak 
stability), which can be seen to amount logically to the open-system 
assumption. From that perspective, the use of classical logic admits a 
closed-system perspective.

NB2 "Proofs of life" contains a reductionist reasoning system that 
admits the cut rule, meaning considerations at the higher level can be 
used to circumvent the need to consider lower-level facts.
