If Quantum Mechanics Hasnt Profoundly Shocked

This statement is attributed to Niels Bohr in various paraphrased forms from his lectures and conversations, though no single definitive primary source has been identified. Bohr made the profoundly counter-intuitive nature of quantum mechanics a central theme of his lectures and writings, particularly in Atomic Physics and Human Knowledge (1958). Quantum mechanics violated classical intuitions about particles, waves, causality, and measurement in ways that Bohr believed required entirely new conceptual frameworks.
