Putnam and others have argued that an examination of structures arising in quantum mechanics can lead to a non-classical propositional logic, quantum logic. In this paper it is argued that the procedure by which quantum logic is said to be discovered, a process called reading off, is ...
Below is a set of truth tables showing the logic operations for Kleene's logic. Lukasiewicz logic真值表略... 简单的解释一下, 在这里Unknown可能是true也可能是false。 因此: 对于Unknown and true 可能是true and true也可能是false and true. 那么结果应该是true或者false. 最终还是不确定. 所以还是Unk...
The Wiki article on Quantum Logic says, “Quantum logic can be formulated either as a modified version of propositional logic or as a noncommutative and non-associative many-valued (MV) logic.” In other words (to me, anyway), itextendsexisting logic (it’s certainly expressed in terms of ...

We have already treated the answering of IF THEN questions in the chain set logic. In sect. 6.4.6, and especially in fig. 6.8, we illustrated cases of drastic differences between answers to IF THEN questions in the chain set logic versus propositional calculus....
Answer to: Prove that if forall x (P(x)wedge Q(x)) and forall x ((P(x)wedge Q(x) ) to R(x) are true, then forall x (R(x) to P(x) ) is also true...
Answer and Explanation:1 The sampled data is: Arranging values of X in increasing order. The general trend suggests that increase in X leads to decrease in Y,...
We formulate a version of the conditional probability of an IF-event considering the Łukasiewicz operations with IF-sets. Also some properties of conditional probability are proved. The results are strengthenings of preceding ones published in [LENDEL
