How did Norbert Wiener's 1948 book help establish cybernetics as an independent science?

Norbert Wiener’s 1948 book, Cybernetics; or, Control and Communication in the Animal and the Machine, is widely recognized as the foundational text that established cybernetics as an independent science.1

The book helped formalize the discipline in several key ways:

• Defining the Scope: Wiener defined cybernetics as the science of control and communications in both animals and machines. By bridging the gap between physiology—specifically the nervous system—and control theory, he provided a unified framework for understanding complex systems.1
• Conceptualizing Feedback: The work highlighted the role of feedback, where a controller adjusts a system's behavior based on information received from a monitor. This concept became central to the study of how both biological organisms and artificial systems achieve desired outcomes.1
• Historical Context: By tracing the etymology of "cybernetics" to the Greek word for "steersman" and linking it to the history of governors, Wiener provided the field with a clear intellectual lineage.1

This publication transformed these interdisciplinary ideas into a distinct field of study, influencing automation theory and computer science for decades to follow.12
