Entropy DOES NOT EQUAL Complexity
This is a question I had too – how do we see order in the world around us if entropy is supposed to be increasing? But what is important to understand is the difference between order and complexity.
If we look at a human, what does it do – fundamentally, we try survive. But surviving involves turning food into energy and using that energy to generate heat, to move, to cause disorder. These all involve complex processes, that may seem ordered, but are actually creating disorder.
Similarly, the sun compresses hydrogen to form helium and releases vast amounts of energy, increasing entropy. There may be several types of coordinated fusion happening but it is all complexity, not entropy.
So why does it happen at all? It is a positive feedback loop. Provide energy to a system and it can do complex things to generate more energy – give a human food and they will think of ways to build tools that help them cause more disorder – it is just a way of speeding up the conversion of order to disorder.
