Chapter 2 of the book The Earth System is dedicated to the Systems. It defines its part, the relations between its parts, and the status. In order to have further understanding on each topic of the Chapter, the main part of it is dedicated to explain each of these, using an imaginary world called Daisyworld. System, Components and State In definition a system, each one of them, is an entity composed of diverse but interrelated parts that function as a complex whole. For example a well know system, is the solar system, which is a collection of eight planets and their moon, that orbit around the sun, together with smaller bodies, such as asteroids, meteoroids and comets. The name of each of these bodies, these individual parts are called components. The state of the system is the ser of important attributes that characterize the system at a particular time, for example in the cardiovascular system of the human body, attributes, like body temperature, level of nutrition and blood pressure, are among the many that designate the state of the system. 2

Couplings Couplings are the links that allow the flow of information between the interrelated components that conform the system. Below there is an example of the two types of couplings that exist in the relation that body temperature has with an electric blanket. Positive Coupling: occurs when both components have the same effect. Example of Positive Coupling: blanket temperature increases, body temperature increases. Negative Coupling: occurs when the components have opposite effects. Negative Feeling: body temperature increases, blanket temperature decreases. (An arrow with a circular arrowhead represents a Negative coupling.) Feedback Loop A feedback loop is a “roundtrip” between couplings, it is a self-perpetuating mechanism of change and response to that change. The denotation of an action changes from being an action to a reaction, by a following action. For instance someone has been judged for some behavior, this would be the reaction of the action 3

the person judged took. This reaction would become an action when it is followed by a reaction to the judgment by the person who has been judged. There are two types of feedback loops: Positive Feedback Loop: the coupling found must be all negative, or all
