Molecules, people, machines, planets, cities, and markets all become chaotic over time. In fact, entropy turns out to be a very powerful tool for understanding and predicting all sorts of physical and even social phenomena. However, it does not explain everything. For instance, it does not explain why life is so darn constructive. Bodies, communities, economies etc, all go from formless to form as well as from form to formless.
Life seems to be the ultimate entropic contradiction.
In the 20th century several groups of theorists began exploring new disciplines to help answer these questions. Such disciplines included Chaos Theory, Fractal Mathematics, Quantum Mechanics, and eventually the study of Complexity. These theorists were interested in figuring out what was missing with entropic theory as well as what was wrong with other foundational scientific paradigms such as Newtonian Mechanics and Darwinian Evolution. Deeply complex and living networks of endless feedback loops were the result of entropy, not the cold, dead of space. At first, self-organization seems counter intuitive.
