What is ENTROPY Explained: The Game Of Energy Disorder
There is such a mysterious and uncatchable quantity in physics, which is not directly measurable and it doesn’t even have a single definition because it changes depending on the framework in which appears. We’re talking about Entropy ( from ancient greek: inner transformation).
What is entropy? What about some examples of entropy? Here is the game of entropy explained.

Physicists and engineers soon clashed with difficulties and experimental limits, which turned out to be sides of the same coin: different aspects straight related to the concept of Entropy.
Hopes were nipped in the bud by British physicist William Thompson, also known as Lord Kelvin, who claimed an experimental principle, based on his studies on heat. This is now called the 2nd principle of thermodynamic:
“In every real termodynamic process, the entropy of an isolated system, can only increase”.
Here the 3rd law of thermodynamics joins the game.
It was formulated for the first time between 1906 and 1912 by the German chemist Walther Nernst, and for this reason, it is also often called Nernst’s Theorem. It states that to reach absolute zero in a thermodynamic process involving a finite number of operations is not possible.
What is the deep reason why entropy spontaneously increases? Why nature behaves this way? The great theoretical physicist Ludwig Boltzmann answered the question in 1871 giving a probabilistic insight based on the microscopic behaviour of the particles.
