# The second law of thermodynamics -> increase in successful projects

Hello, residents of the Habr.

I want to tell you how to increase personal efficiency using the knowledge of simple physics and simple theoretical / logical conclusions.
So, Wikipedia says that the second law of thermodynamics is not a law, but formulated postulates that were first put forward and voiced by two scientists:
• Rudolf Clausius postulate - “A process is impossible, the only result of which would be the transfer of heat from a colder body to a hotter one.”
• the postulate of William Thomson (Kelvin) - “A circular process is impossible, the only result of which would be the production of work by cooling the heat reservoir.”

In the context of self-development, we are more interested in the first Clausius formulation. Whence comes up that if you put a hot body and a cold one nearby, the first one will start to cool, and the second will heat up and over time they will both compare in temperature. It seems like this is another obvious conclusion, but the German scientist saw this as a natural law, which formed in this way: "The entropy of isolated systems tends to the maximum ."

Why is this law so important in personal development, self-realization, in business, startups, any business? The English writer Charles Snow compared ignorance of the second law of thermodynamics with a lag in overall development and demanded that this be equated with ignorance of Shakespeare's plays. This wording will say little to us, I think not many experts read Shakespeare from the IT field, but I think everyone has heard about the second law of thermodynamics.
So Entropy- This term indicates a trace of energy dissipation. The word entropy can be replaced by the word mess, or chaos. Chaos is the opposite of order. Turning to Dahl’s dictionary, we understand that order - “This is a collection of objects standing in a row, side by side, side by side, it is unlikely to be scattered, not vskid, but one after the other; row, line, rank, order; each side of the street, a row of houses, forms an order. ” From this we can conclude that entropy is the opposite of order. The order can be understood literally, as the arrangement of objects "in rows" and it seems to me best to explain this with the example of the sea. There are always waves on the sea, there is never 100% calm, because the sea is not an isolated system. But if theoretically, imagine it isolated and exclude everything that affects the appearance of waves - wind, earthquakes, living creatures,
S = 1. In the real world, entropy always tends to 1, but less than it. If we add the wind to our imagined sea, we will see that it caused waves that build up and go to the shore with a ridge, or nearby. The stronger the wind, the stronger the waves it causes, it can even cause a storm, in these cases there is a certain order when the sea is divided into rows-ridges, and they all rush to the shore with wind speed. But each wave, no matter how tall and long it is, first and foremost seeks to fall into the sea and fill the gap between the rows as soon as the wind ceases to influence it.

###### Let's draw the first conclusions:

1) Order does not tend to the maximum like entropy. Order is the effect on something, as a result of spending a certain amount of energy.
Each house built is also a peculiar series, any mountain, rock, and all this does not strive for order, everything strives for destruction, any house will fall apart, mountains will turn into plains, trees will die off, rocks will crumble.
2) Entropy is also a degree of equilibrium. Its order tends to 0.
3) The formulation of the Clausius postulate tells us that increasing entropy is a natural process. She is always growing.
4) Sometimes we can observe a decrease in entropy. But this is possible only due to the fact that in another part of the Universe it will increase more. A new skyscraper in your city is the emergence of a new series, and temporarily it definitely reduces entropy, but only temporarily because any house will once collapse, and this will make entropy even stronger.

##### We draw important conclusions:

First conclusion: Any system lives due to the destruction of other systems.
We all live thanks to the sun, which burns down -> water, what we drink -> vegetation -> air -> animals. We use their energy.
The second conclusion: Any system lives by receiving energy from outside.
The third conclusion:The more foreign energy the system uses, the less its own entropy. This is the most important conclusion that leads us to what I want to say. The more you spend your own energy on routine work, when your dedication is at its limit, but you, like a brave horse, rush into a team, think, maybe you should hire another horse for yourself? When we spend energy, we run out of breath, and until our energy is restored again, little is needed from us. But if we spend other people's energy, even using other resources, ours remains intact.

I think I will not make a mistake if I say that the second law of thermodynamics is much more important than Shakespeare’s plays for modern people. You see, it often happens that you take up work and put yourself in the framework, “I'll do it myself, I know / learn everything” as a result, either the project is delayed, or even possible -> break. Therefore, for personal effectiveness and success, you need to use other people's energy / knowledge / skills / products for your own purposes, use their mistakes, work, libraries and modules, not create a bicycle for the thirty-third time, and of course remember the second law of thermodynamics. For in modern life, not the strongest, fastest, smartest becomes successful, but the one who remembers this beginning and uses it on time and skillfully.
