Intellectual Foundations
Development of the theoretical building blocks that would inform Exodology.
Norbert Wiener publishes "Cybernetics," establishing feedback as central to understanding system behavior.
Ludwig von Bertalanffy formally proposes General Systems Theory, arguing for studying wholes rather than parts.
