Module 4: Propositional Logic Proofs
... • We can build a combinational circuit matching any truth table. • We can build any combinational logic circuit using only 2-input NOR gates. • The maximum number of swaps we need to order n students is n(n-1)/2. • No general algorithm exists to sort n values using fewer than n log2n comparisons ...

A Brief Introduction to the Intuitionistic Propositional Calculus
... In the effort to pin the intuitionists down, a number of formal semantics for various intuitionistic calculi have been proposed. These semantics have been proposed in the attempt to pin the intuitionists down to a particular logical system, and in consequence typically attempt to formalize some intu ...

No; he claimed to be in the right, to have reason on his side, to be pointing pout to us where the truth lay. But how could this b ...
