Feedback system

/ˈfiːd.bæk ˈsɪs.təm/noun
ELI5 Mode🧒

A feedback system is a self-regulating mechanism that uses the output of a process to influence or adjust its own input, helping to maintain stability or achieve specific goals. This concept is foundational in fields like engineering and biology, where it can either amplify changes (positive feedback) or dampen them for balance (negative feedback), making it essential for modern technologies that adapt in real-time to dynamic environments.

Feedback systems were key to the Apollo 11 moon landing in 1969, as the spacecraft's guidance computer used continuous feedback loops to make real-time adjustments, preventing errors that could have derailed the mission—proving how a simple concept can enable humanity's greatest feats in space exploration.
