Complex systems are widespread in many areas of science, and we encounter them every day in the most varied situations. Examples include financial markets, road transportation networks, telecommunications networks, global and national economies, social networks, immune systems, living organisms, ...

Biology and medicine, from molecules to landscapes, are ideally suited to entropy or information approaches, because biological systems are highly variable, with stochastic processes:

• Innovation (mutation, epigenetics, recombination, speciation)
• Transmission of informatio...

In 1948 C. E. Shannon published his paper “A Mathematical Theory of Communication” in the Bell Systems Technical Journal. He showed how information could be quantified with absolute precision, and demonstrated the essential unity of all information media. In brief, he introduced four ...

The field of non-equilibrium phenomena is growing in interest day by day; in fact, one may argue that almost any observable macroscopic phenomenon occurs in non-equilibrium conditions. To make any sense, this statement requires a definition of equilibrium, the status that must be violated for non...

In calling for papers we are guided by two remarkable aspects of the subfield of Quantum Information Science (QIS): (i) Like thermodynamics, motivated and driven by practical concerns, it uncovers new foundational principles, and (ii) it provides a conceptual framework that unifies and changes th...

In 1972, John W. Tukey stated, “Data analysis has to analyze real data. Most real data call for data investigation, while almost all statistical theory is concerned with data processing. This can be borne, in part because large segments of data investigation are, by themselves, data process...

Statistical physics is a branch of modern physics that employs probability theory and statistical tools to inquire about the physical properties of systems formed by many degrees of freedom.

Although its origin can be traced back to the last decades of the 1800s, when a young Ludwig Boltz...

Thermodynamics, a cornerstone of physics, explores energy and its transformations, particularly concerning heat, mechanical work, and the interplay of various energy forms. Its historical journey traces a path from empirical observations to systematic laws, shaping our understanding of physical s...

Time is a perennially challenging subject of physics. This section of Entropy seeks submissions on the subject of physical time, in particular: (i) time in relation to the notions of entropy and the arrow of time; (ii) time considered from a contemporary perspective; (iii) time considere...
