Quick takeaways
- Computation is defined by the application of rules governing system operations, encompassing both human-directed and natural processes that yield observable outputs.
- The principle of computational equivalence reveals that simple systems can perform complex computations, challenging the notion that complexity requires intricate rules.

Understanding Computation
Computation is defined as the application of definite rules that govern how a system operates. It occurs both in human-directed scenarios, where we seek specific answers, and in natural processes that operate independently of human intent. The distinction between mechanism and purpose in computation is nuanced, as any observable output can be construed as fulfilling a purpose defined by the governing rules. This suggests that anytime a system adheres to defined rules and generates outputs, it can be considered as engaging in computation.
