WCFSGS' Version: Generalized Second Law of Thermodynamics

We have known that there has been some generalization to the second law of thermodynamics.

We like to present here the Version of WCFSGS about this generalization. At this moment, we are not quite sure if our version is different from the version presented by western scientists.

Generalized Second Law of Thermodynamics

Regardless of being OPEN or Closed as the systems are, the Tendency of Equally Extending Everywhere will make the decrease of the system entropy as small as possible under any type of constraints. For the closed systems, the minimal decrease of the system entropy is negative which means that the systems will tend to be with a maximal increase of the system entropy.

For us, an open system's decrease of the system entropy can always be considered as a result of some constraints. However, under any type of constraints, there is a maximal Tendency of Equally Extending Everywhere causing the decrease of the system entropy as small as possible.

For example, imagine that a group of employees go to the conference hall to have a business meeting. In the extreme case, if the boss does not say anything, each of the employees will randomly pick a position to sit down. If the boss says that "You can only sit down within the rows of 31-35, each of the employees will randomly pick a position to sit down within the rows of 31-35. When the boss says that "You must sit down according to the number assigned exclusively for you", the employees will sit down according the the numbers which they got. However, their heads will still move around......

It is obvious that the constraint from the boss is the root-cause for the system entropy to decrease. However there is always a Tendency of Equally Extending Everywhere which makes the decrease of the system entropy as small as possible.

WCFSGS thinks that our version may be a solution to the "contradiction" between the second law and the increase of the complexity and the order in Mother Nature.

There is no contradiction between the second law and the increase in complexity ("decrease in entropy") in nature. The earth is not a closed system, so the second law does not apply to it. The entropy decrease on Earth is compensated for by the entropy increase of the whole universe. Essentially, the Earth takes in low-entropy radiation from the sun, uses it to create "complexity" (decrease entropy) and then radiates away higher-entropy radiation. This higher-entropy radiation is what compensates for the decrease in entropy on Earth.

Agree. " " means that the "Contradiction" is NOT True.

Here, we like to present our version of the Generalized Second Law to cover the cases for Open Systems.

Instead of always using the special Second Law to explain everything thing, we can use the Generalized Second Law for open systems allowing a decrease of the entropy being to the possible minimal extent.

In reality, except for the WHOLE OF THE UNIVERSE as you can imagine, there is actually NO 100% closed system. We thus think that a generalization to the Second Law is necessary to cover the cases for the open systems in reality.
