I recently wrote on the subject of entropy here, and set off a maelstrom of comments. Some people just have that gift, and other people don’t. That appears to be just the way it is for me, and I try to be humble about it. Sometimes I think my comments section is a good example of entropy.
If I might, I would like to supplement my initial observations with a few quick follow up jabs, and see if it happens again. These are just quick responses to a couple of basic questions that were raised, and which I would like answer outside the thread.
Since I speak English, let us go with a dictionary:
Entropy is “a thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.”
Now I don’t see anything in my argument or illustrations that would constitute a howler when it comes to that definition. Assuming that this is a reasonable English expression of what entropy means, it also means that applications to the question of evolution are entirely reasonable. Entropy increases over time, meaning that disorder and randomness are also increasing. But evolution requires us to believe that the disorder and randomness are decreasing.
In order for that disorder and randomness to decrease, it is necessary to have a transfer mechanism that can utilize available energy (in a closed system) or newly imported energy (in an open system) into mechanical work that is productive.
Otherwise, any energy, new or old, will simply dissipate. The energy will get tired and take a nap. The energy will go bye-bye. We might exhort that energy not to take it lying down, and we might urge the energy to “not go gentle into that good night.” “Old age should burn and rave at close of day; Rage, rage against the dying of the light.” Sure, rage all you want. Rage against the heat death of the light, for all the good it is going to do you.
Now the point of my illustration in the previous post is that the transfer mechanism that can make energy useful is itself an example of decreased randomness, and hence it is also something that must be accounted for.
