A simple definition of entrophy and how it relates to chaos theory?
Entropy is the amount of Energy that is not available for work during a certain process and in other words the energy form of a system that relates to its internal state of disorder, (high entropy levels are disordered states, low entropy levels are characteristic of ordered states).Entropy in general is based on the SECOND LAW OF THERMODYNAMICS.As far as entropy and the chaos theory is concerned there is a very simple connection.Nothing happens without making the universe a bit more disorganised, in general there is a tendency of available energy to dwindle (it is true that in some billion of billion of years there will not be any more energy in a form that we can use) and entropy is a measure of the systems-universe disorder.Have a nice day.
