To demonstrate how computers work, [Alex Gorischek] has made a physical example of how binary logic gates work using pulleys and weights.

Logical formalisms necessarily discount paradoxes as anomalies open to more advanced understanding, worked around by restrictions to logic or ignored as nonsensical. The 1-D geometric model takes an ...

A mathematical proof is irrefutably true, a manifestation of pure logic. But an increasing number of mathematical proofs are now impossible to verify with absolute certainty, according to experts ...
