Cybernetics is a broad area of study that focuses on self-referential processes like feedback. 

The field was given its name by Norbert Wiener, who was inspired by an example of circular causal feedback: the act of steering a ship, in which the helmsman makes adjustments to the steering according to the effect it is observed as having, allowing the vessel to maintain a constant course despite external forces like crosswinds and the tide.

In addition, Cybernetics has had a significant impact and has been interpreted in various fields due to its multiple branches.

Evolution

The Greek word kybernetes—which might mean rudder, pilot, a device used to direct a boat, or something that aids in human governance—is where we get our modern word "cybernetics." This term, initially employed by Plato in Alcibiades, refers to the administration of a population. French physicist Ampere coined the term in the 1830s to describe the emerging field of political science. What Norbert Wiener called "the study of control and communication in the animal and the machine" is what we now call "cybernetics."

Principles of cybernetics

In recent years, scientists have had a noticeable hesitance to employ the term "cybernetics" due to its extensive scope, including various principles and applications across several domains of human pursuits. However, it is crucial to comprehend the fundamental principles of cybernetics, including the concept of feedback, to grasp the intricacies of complex systems. The system incorporates two feedback loops that facilitate learning and adaptation. The first feedback loop, employed with regularity, facilitates incremental modifications and the learning process. 

On the other hand, the second feedback loop, utilized less frequently, detects the necessity to replace outdated information with fresh information, enabling the system to adapt. As per Ashby's perspective, learning entails a system's ability to discern and replicate patterns of efficacious conduct inside its operational environment while concurrently evading failed activities. Adaptation refers to the process through which a system acquires a novel behavioural pattern after recognizing that the environment has changed, rendering the previous pattern ineffective.

Applications

The core notion of circular causality in cybernetics has broad applicability, resulting in various applications and connections with other disciplines. A significant portion of the early applications of cybernetics mainly centred around engineering and biology and the intersections between the two. These applications encompassed areas such as medical cybernetics, robotics, neural networks, and the study of heterarchy.

Within the social and behavioural sciences, cybernetics has played a significant role in shaping and impacting several disciplines, such as anthropology, sociology, economics, family therapy, cognitive science, and psychology.

Conclusion

The field of cybernetics has seen expansion, encompassing several domains like management, design, teaching, and the creative arts. Additionally, it has established connections with constructivist philosophies, counter-cultural movements, and media studies. The emergence of management cybernetics resulted in a range of practical implementations, most notably in the context of the national economy of Chile during the Allende government's tenure through Project Cybersyn. The field of design has experienced the significant influence of cybernetics in various domains, including interactive architecture, human-computer interaction, and design research, as well as the advancement of systemic design and meta-design methodologies.

Furthermore, the extensive range and inclination of cybernetics to surpass disciplinary conventions have resulted in the continual evolution of its boundaries, rendering them challenging to delineate precisely.
