99 Mental Model Entropy is the highest law of all the laws of nature

I'm sure many of you have heard of the law of entropy increase, which is a law that makes scientists feel hopeless. Why? What exactly does this law mean? What can be done to combat this law?

Let's give some examples from life to help us understand this law.

In short, water can only flow from high to low; Hot food will slowly get colder; Mobile phones and computers will be more and more stuck; The room will become more and more chaotic, and the garbage will be piled up with nowhere to stay; Your clothes will be more and more worn; Your days will also get more and more chaotic ......

It reveals the ultimate law of the evolution of the universe and includes the laws of evolution of all non-living and living organisms.

Doesn't that sound hopeless? Because everything is predestined and cannot be changed.

Then the only way we can make our lives better is to fight entropy.

The process of a person's growth collapses, and it is a process of negative entropy.

Refuse to think firmly, uphold an open mind, insist on lifelong learning, understand and absorb new things;

At the same time, break the path of dependency, have the courage to try, use new methods to challenge new projects, and fight burnout;

Insist on exercising in life, go to bed early and get up early, overcome the weaknesses of human nature, and stay awake at all times;

Clean your desk and living room frequently to keep them tidy and hygienic.

Every tiny act of self-indulgence follows the law of entropy increase, and the self-discipline and filial piety that have been built up with great difficulty fall short.

The process of combating entropy increase, while anti-human, is the only way we can lead to a better life.

Many people say that the law of entropy increase is the most terrible law in physics, and it affects our lives all the timeThe phenomenon of the law of entropy increase happens all the time in our livesFrom cosmic stars to particle quarksThere is no escape from himClaws. <>

The definition of the entropy increase theorem is:Heat flows from a hot object to a cold object。Most people may be discouraged when they see this sentence, and they don't understand the meaning, but in fact, a common particle in life can help you understand the meaning, for example, on a hot summer day, you just finished playing basketball, it's hot, and you think that it would be nice if you could eat a popsicle, and in the time you think, you came to the commissary to buy a popsicle, but before you have eaten a few bites, the popsicle turned into a puddle of water, and then you will complain, this sun is too poisonous, right? But have you ever wondered why this is happening?

In fact, this is a manifestation of the law of entropy increase. We all know that it is very high, and the calorie of the popsicle is very small, and this is when the law of entropy increase occurs. <>

To the above example is just a manifestation of it, we must first understand what entropy is to understand the law of entropy increase, it is one of the parameters that characterize the state of matter in thermodynamics, proposed by the German physicist Clausius in 1865, and Chinese physicists in 1923 according to the meaning of heat and temperature quotient for the first time translated him as "entropy", which is defined as heat is proportional to the amount of matterHis physical meaning is a measure of the degree of chaos in the systemNothing can fight the law of entropy, and we all know that the sun has a lifespan, although it is nowIn the prime of life,But there will always be a day when it goes out, and the phenomenon of the law of entropy increase has been happening all the time as the sun goes out. <>

So, the law of entropy increase actually happens all around usAny corner, encompassing everything in the world, and there is no means to counter it, no wonder many people say that this is the most terrible law in physics, because it affects us all the time.

Because things are always moving in the direction of entropy increase, everything that conforms to entropy increase is very easy and comfortable, such as laziness. The law of entropy increase tells us that everything is moving towards irregularity, towards disorder and chaos, and if you want to become self-disciplined, you have to work against entropy increase, and the process will be very painful.

When the player's foot is injured, the ambulance staff will take an ice pack to apply it as soon as possible, which can make the heat on the foot quickly transfer to the ice, and this energy transfer is spontaneous. The condition for this transfer to be established is that the energy must spontaneously transfer from high temperature to low temperature, which is the spontaneous state of energy. This is one of the laws of entropy increase.

For example, the washing machine in modern family life, in order to be more convenient in life, this machine was invented. Looking at things from the surface is mainly to improve the efficiency of the laundry and save time. But many people ignore that washing machines will consume during the cleaning process.

It can affect the probability of something happening, such as a rainy day. The weather forecast says that it may rain tomorrow, but the chance of rain is uncertain, and we don't know if we want to bring an umbrella

Entropy increase is a spontaneous process that develops from order to disorder. If a room is left uncleaned for a long time, it will become more and more messy, which is the result of increasing entropy. If there are no rules in a school, the students will get worse and worse.

Some people rush to the law of entropy increase is a law that makes people despair, and call the law of entropy increase the most terrible law in physics. The person who proposed this law shows that he thinks it is in a closed system. The heat is from high temperature to low temperature, from order to disorder, as if I am exposed to new knowledge every day, and as the knowledge continues to increase, one day this knowledge will be chaotic in our minds, which will cause disorder.

The most terrible discovery in physics, the law of entropy increase, is that everything will eventually die.

Because no matter how much it changes, the entropy (disorder) in the universe will increase steadily, which is something that has been decided since the beginning of the universe, and it is also the most scientific law. The universe was originally just a "point", and the interior of the universe at this time was relatively orderly, but after the universe became larger, material energy began to surge out, spreading to all corners of the universe, and the disorder of the universe began to gradually increase, almost in an unstoppable state.

The material energy of the universe gradually gathers into nebulae and forms various galaxies, but from a macroscopic point of view, the universe has not stopped expanding, and the disorder of the entire universe is also increasing.

1. The universe will eventually become a completely disordered "void":

The reason why the universe continues to expand at an accelerated rate is believed by most scientists to be played by dark energy.

Unlike ordinary matter, dark energy does not provide gravitational force in the universe, but provides repulsion, and the vast majority of material energy in the universe is composed of dark matter and dark energy, so the universe as a whole is constantly accelerating its expansion.

The expanding universe and the increasing entropy value make the future of the universe hopeless - as the universe expands, the distance between matter becomes farther and farther away, and the matter in the galaxy will eventually be swallowed by black holes, and eventually the universe is only left with black holes, and the black holes are dissipated by Hawking radiation, and the last universe is only a piece of nothingness.

2. All matter in the universe tends to be disordered

If you drop a drop of paint into water, the pigment will melt and spread, increasing disorder, almost all matter in the universe has the same properties, even us humans, if the room is not cleaned, it will end up being very messy.

This increase in disorder is the law of almost all matter in the universe, and it is very likely that it is the absolute law of the universe in which we live, so the law of entropy increase is also called the most scientific law.

If human beings really understand the law of entropy increase, they may be able to turn it into a reversible phenomenon, just like the end of the expansion of the universe is nothingness, if human beings can reverse the increase in entropy, they may be able to cause the "great collapse" of the universe and return the universe to an orderly state.

The universe we live in has its own physical laws, and if there are other parallel universes, there may be other physical laws.

In the current universe, we see the law of entropy increase, and perhaps in another parallel universe, the whole universe is completely opposite, and the universe has been collapsing and eventually becoming a "point".

According to the parallel universe theory, each universe may have its own independent physical laws, and these physical laws are completely incomprehensible rules for life in other universes

Now cosmology points out that everything in the world today is transformed by energy, and therefore, the quality of energy determines our mass universe. The two basic characteristics of energy are the law of conservation of energy and the law of entropy increase, which basically determine the construction law of the mass-state universe. Among them, the law of entropy increase is the core of the core, Einstein called him the highest law, the law that is least likely to be falsified, and this law is also known as the most desperate law of life.

For example, the air conditioning in our room, the refrigeration process, the heat is transferred from the low temperature room to the high temperature air outside, as long as it is a spontaneous process of reverse energy, there must be an external force to do the work, the air conditioning is to compress the energy from the low temperature room to the high temperature air through the compressor.

The reason why the structure exists is because of the law of entropy increase, that is, because of the decay of energy, even the original non-structure, such as the singularity, it also decays out quarks, leptons, bosons, and then any individual or structure, when the energy decays to a certain extent, it can not exist alone, at this time it must enter the structure to exist, it must evolve.

This state of energy can be seen everywhere in our lives. That is, the spontaneous state of energy, which is always flowing from high temperature to low temperature, which is the most basic definition of entropy. From this definition, our law of entropy increase is derived:

In the system of isolated forces, entropy does not decrease unless there is an external force.

Why does the law of entropy increase make people desperate? Even Einstein did not dare to slack off, calling it the first law!

The stipulator of everything is the law of entropy increase of energy, and the structure presents a process of anti-entropy increase under the law of entropy increase, which is the product of both the law of entropy increase and the product of anti-entropy increase, and if it does not do so, it cannot exist. Therefore, we say that all things are in existence, which is the only purpose for the evolution of all things.

This is the power of the law of increasing energy entropy, everything evolves under its regulations, and the evolution expressed by life is also the process of having to evolve under its drive.

According to modern cosmology, from the energy singularity 13.7 billion years ago, that is, the highest point of energy, and then the energy decays all the way, if we deduce the decay of energy to the extreme, eventually the universe will reach the lowest point of energy, and at that time, the energy will no longer flow, reaching the end of the great silence of the universe, which is the so-called heat death.

Then, at that point, no structure will be able to gain energy anymore, which is why the law of increasing entropy is called the most desperate law of life, a law so universal that Einstein called it the most of all the laws of science, the law that is least likely to be falsified.

Why does the law of entropy increase make people desperate? Even Einstein did not dare to slack off, calling it the first law!

The law of entropy increase means that the conversion and transfer of energy is directional, and the heat of the low-temperature heat source will not be spontaneously transferred to the high-temperature heat source, and the heat cannot be spontaneously converted into work. The value of entropy only gets bigger and bigger, and it is irreversible. This law foreshadows the inevitable irreversible destruction of the universe, which means that sooner or later humanity will disappear.

The entropy reduction of life has no effect, after all, in the vast universe, human beings and other life are simply negligible. The inevitability and irreversibility of entropy increase doom life to develop from order to disorder, and eventually to aging and death. So the entropy increase principle is also known by many people:

The most desperate laws of physics. (According to the principle of entropy increase, all life on earth will go from order to disorder, that is, to death!) ）

The law of entropy increase must be embodied in the living system, and we human beings can be described as very small existence in the universe, which can be completely ignored. When people feel that everything they are destined and cannot be changed, they will feel "hopeless".

Because this law must be embodied in the system of life, but in the universe, human beings are almost negligible, so it is very desperate and makes people feel that human beings are very small.

Why does the law of entropy increase make people desperate? Even Einstein did not dare to slack off, calling it the first law!

The law of entropy increase can make the energy and heat of the universe reach higher and higher, until the energy and heat of the universe can no longer be exchanged, and the energy and heat of the universe begin to change from order to disorder, and when the universe reaches thermal equilibrium, time has no meaning.

From a physical point of view, we can think of entropy as a physical quantity that measures the degree of energy chaos in a system. The system with the bottom of entropy has a high degree of order, and the system with high entropy is more chaotic. From the perspective of energy, it can be understood that energy cannot be utilized by 100% in the process of conversion, and there is always part of the energy that is consumed and turned into chaotic and disordered heat energy.

This part of the energy leads to an increase in entropy, and the law of entropy increase can be derived in many natural phenomena. Because this is the natural direction of development in nature, which is the transition from order to disorder.

The law of entropy increase also has a very intuitive explanation in physical molecules, that is, due to the exchange of energy such as collision between molecules, all molecules will have a variable layer, irregular chaos and disorderly relative motion with the lowest tendency, and there will be no huge difference between the local molecular velocity and the surrounding molecular velocity. On the macro level, the energy of matter has a tendency to convert to thermal energy, just like the conversion from high temperature to low temperature, because temperature is the disordered movement of molecules, which is a physical property.

s w This is the Boltzmann transport equation, and a classic example of the system described by this equation is a fluid with a temperature gradient in space. The particles that make up this fluid flow heat from hotter to cooler regions through a random and biased flow. The other thing is that we also need to understand the concept of entropy.

Order and disorder are just easy to understand, in fact disorder is the meaning of high probability, and order is small probability. Things always develop in the direction of high probability, which is to increase entropy.

The law of entropy increase is also a law of despair, if the whole universe is imagined as an isolated system, then the entropy of the universe will increase more and more, until the universe no longer exchanges energy, and if there is no exchange of energy, the universe will stop functioning. This is the "heat death theory". When the entropy reaches its maximum and no longer increases, and the whole universe reaches thermodynamic equilibrium, it is uniform everywhere, and time loses its meaning.

In general, more and more entropy in the universe will make the universe have no energy and will stop running, it will also make the universe change from ordered to disordered, so that the universe will reach thermodynamic equilibrium, and then time will be meaningless in the universe.
