THE Entropy is a widely studied concept in physics and even philosophy.. It is a way of explaining how events occur around us that represent the degree of disorder in a system. This idea was first proposed by German physicist Rudolf Clausius while studying the principles of thermodynamics in the mid-1850s.

The fact that entropy can be defined in different ways leads some to question its scientific validity. However, many scientists argue that this perception is wrong and that its existence can be revealed even with scientific measurements. After all, almost everything in the universe is subject to spontaneous changes that occur in an irregular manner.

For example, some experts suggest that life itself is linked to entropy. All living things face moments of disorder during their life journey and will inevitably become ill and perish. The same seems to be true of the universe, which is heading towards final collapse; When that happens we probably won’t be here anymore.

some physicists To state that entropy, one of the basic principles of nature, is inevitable. It is not surprising that this term is also used in the second law of thermodynamics, which states that the entropy of an isolated system tends to increase with time.

This means that the available energy is distributed more and more homogeneously, reducing the system’s ability to “do work”. Although organized processes can occur in open systems, the tendency is for energy to dissipate, making ‘organization’ more complex and distant over time.

In other words, everything can start out neatly and steadily. but over time it will result in disorder and unpredictability.

“Entropy is the measure of the thermal energy of a system that cannot be converted into useful work per unit temperature. Because work is obtained from the orderly motion of molecules, entropy also represents the degree of molecular disorder or randomness of a system. This concept offers a deep understanding of the direction of spontaneous changes in various daily events,” explains the encyclopedia Britannica.

What is entropy?

Although German physicist Rudolf Clausius coined the term entropy, the study of this concept began with French engineer Sadi Carnot. In 1824 he published a book on the motive power of fire. It paved the way for new advances in thermodynamics and explained some of this proposed disorder in entropy.

In his work “Reflections on the Propellant Force of Fire”, Sadi investigated the operation of thermal machines and showed that their efficiency depends solely on the temperature difference between hot and cold sources, regardless of the fuel used.

Decades later, German physicist Rudolf Clausius developed these ideas and formulated the Second Law of Thermodynamics in 1865, introducing the concept of entropy.

Scientist showed that energy tends to dissipate and become less available, and the total entropy of an isolated system never decreasesbringing natural processes into an irreversible state of thermal equilibrium.

There are four laws of thermodynamics in total:

  • Zero law: describes temperature and thermal equilibrium;
  • First law: Energy is conserved and can be transformed;
  • Second Law: Entropy always increases in isolated systems;
  • Third Law: Entropy is minimum at absolute zero.

The concept of entropy was introduced by Clausius to describe the irreversibility of thermal processes and formalize the Second Law of Thermodynamics.

Over time, this idea has been applied to various fields of knowledge. An example of this is the work of American physicist ET Jaynes. He used the concept of entropy in information theory and the statistical formulation of thermodynamics to enable a probabilistic approach.

In practice, entropy explains why objects naturally tend to wear out, spread out, or lose organization over time. Imagine an ice cube outside the refrigerator: It melts as heat from the environment radiates, making the energy more dissipated and less available.

This behavior is closely linked to the Second Law of Thermodynamics, which states that the entropy of an isolated system always increases. In other words, over time everything tends towards disorder and thermal equilibrium, as in dissipated heat or a car that does not repair itself.

“The idea of ​​entropy provides a mathematical way to represent the intuitive notion of what processes are impossible even without violating the fundamental law of conservation of energy. For example, a block of ice placed on a hot stove will necessarily melt when the stove cools. The encyclopedia Britannica adds: The process is called irreversible because the slightest change will not cause the melted water to turn back into ice as the stove heats up again.

Entropy is associated with disorder and irreversibility of processes in physics, mathematics, information theory, and even as a metaphor in studies of sociology and philosophy. In a social context, the term is used to describe the tendency towards instability and collapse of organized systems. Perhaps the possible collapse of society due to climate change has something to do with the entropy of the universe.

Although it emerged in thermodynamics to explain heat transfer and energy conversion, over time the concept began to be studied in other fields and became fundamental in many fields of science.

Energy spreads, organization disappears, and everything moves towards disorder. Could this process of natural entropy reveal the fate of the cosmos? So, take the opportunity to find out how the ‘Mirror Universe’ hypothesis can explain cosmic inflation. Until next time!
