Entropy theory

Entropy theory, originating from thermodynamics and extended to information theory, measures the level of disorder, randomness, or unpredictability in a system. In simple terms, higher entropy indicates greater chaos or lesser organization, while lower entropy reflects more order and structure. For example, in a sealed room, entropy increases as things become more disorganized over time. In information, entropy quantifies uncertainty—more entropy means less predictability. Overall, entropy provides a way to understand how systems evolve toward states of greater disorganization or unpredictability.
