Zelfconsistentie

Zelfconsistentie is a term that describes a state where a system or theory is internally consistent, meaning its various parts do not contradict each other. In simpler terms, a self-consistent system adheres to its own rules and logic without producing any paradoxes or logical impossibilities.

The concept of self-consistency is particularly important in fields like mathematics, physics, and computer science. In mathematics, a proof is considered self-consistent if it logically follows from its axioms and previously established theorems without any internal contradictions. In physics, a theory is self-consistent if its predictions and postulates do not violate fundamental physical laws or lead to paradoxical outcomes. For instance, in quantum mechanics, certain interpretations aim to be self-consistent to explain observed phenomena.

In computer science, self-consistency is crucial for databases and algorithms. A database is self-consistent if all data entries adhere to predefined constraints and relationships, ensuring data integrity. Similarly, an algorithm's logic must be self-consistent to produce predictable and reliable results. The absence of self-consistency can lead to errors, failures, and unpredictable behavior in complex systems. Ensuring self-consistency often involves rigorous testing, logical analysis, and adherence to established principles within a given domain.
