Entropy describes the quantity of ambiguity and disorganization within a system. In physics, it is a measure of a system’s energy diffusion; it is a thermodynamic quantity for the unavailable thermal energy needed to achieve mechanical work. For instance, you bought a good cup of hot coffee and it took an “organized thermal energy” to make it. You then left it on your desk to attend to something else. However, you forgot about it and when you came back to drink it, it was already too cold. Hence, “entropy” happened as the coffee lacked enough thermal energy for you to drink it, for “order” to ensue.
In information technology, entropy happens when there is an unpredictable signal in the cybernetics system. This is manifested as choppy communication, dropping calls, and too much static. In cities where there are sufficient cell towers, there is ample energy to sustain the signals, hence, the entropy is low.
In psychology, entropy refers to sufficient tension for positive change to transpire. For instance, Carl Jung, a Swiss psychiatrist and psychoanalyst, emphasized the importance of psychology entropy by saying, “there is no energy unless there is a tension of opposites”. Such energy dispersal is necessary for the "color" to happen in one’s life. One of Jung’s patients aptly stated, “I don’t know what you are going to do with me, but I hope you are going to give me something that is not gray”. Moreover, in psychotherapy, the client needs to be aware of his entropy, the inner conflicts that he is experiencing, so he can be more in charge of it.
