Coupled

== Coupled ==

Coupled refers to the state of being connected, linked, or associated with another entity. This term is widely used across various fields such as physics, chemistry, biology, engineering, and social sciences to describe systems, processes, or entities that interact with each other.

Physics

In physics, coupled systems are those in which two or more components interact with each other. This interaction can be through various forces such as gravitational, electromagnetic, or nuclear forces. Examples include coupled oscillators, where two or more oscillating systems are linked, and coupled pendulums, where the motion of one pendulum affects the motion of another.

Chemistry

In chemistry, coupling refers to the process where two chemical species are joined together. This is often seen in organic chemistry with reactions such as cross-coupling reactions, where two different organic molecules are joined together with the help of a catalyst. Another example is coupled reactions, where an energetically unfavorable reaction is driven by a favorable one.

Biology

In biology, coupling can refer to various processes where biological entities interact. For instance, in cell biology, signal transduction pathways often involve coupled reactions where the activation of one molecule leads to the activation of another. In genetics, gene coupling refers to the phenomenon where two genes are inherited together more frequently than would be expected by chance.

Engineering

In engineering, coupled systems are those where different components or subsystems interact with each other. This is common in mechanical engineering with systems like coupled gears or in electrical engineering with coupled circuits. The study of these interactions is crucial for the design and analysis of complex systems.

Social Sciences

In the social sciences, coupling can refer to the relationship between different social entities. For example, in sociology, coupled relationships refer to the interactions between individuals in a social network. In economics, coupled markets are those where the behavior of one market affects another.
