A constant and a possible Nobel of Physics

28 Aug

Constantino Tsallis (1943-), of the Santa Fe Institute is a Greek who is in Brazil, AentropiaMaxBoltzand is a candidate for the Nobel Prize in Physics this year, he also has brazilian and arngetine nationalities, as he likes to say: “he and the fans of Flamengo (big soccer club in Brazil) hope for this Nobel of Physics “.
He reworked Boltzmann’s constant to the point of making it more generic, more applicable, and about to change its name (or create a more general constant) called Tsallis.
The Boltzmann constant (k or kB) is the physical constant that relates temperature and energy to molecules, kMols as we have learned (or not) in physics classes.
The name is due to the Austrian physicist Ludwig Boltzmann (1844-1906), who made the most important contributions to statistical mechanics (even being considered its founder), in which its constant has a fundamental role. Its experimental value, in SI units, determined in 2002, is:
K = 1.3806503. 10 ^ -23 J / K
The simplest way to arrive at the Boltzmann constant is to divide the constant of the perfect gases by the constant of Avogadro.
But the contribution does not stop there, the most important concept that comes from physics is that of entropy, and together with Maxwell (although they have never worked together), they constituted what is called the Maxwell-Boltzmann distribution to visualize the particle velocity distribution At different temperatures.
Constantine Tsallis, a Greek-American physicist who currently works in Brazil, in reviewing Boltzmann’s constant, he says only for the beauty of the equations,
Formulated in 1988 by Constantine Tsallis as a basis for generalizing standard statistical mechanics, it can be said almost to refound, it is a generalization of the Boltzmann-Gibbs Entropy, since Gibbs’s Particullah has recently been confirmed experimentally and is also a fundamental result For Standard Physics.
The physical relevance of Tsallis ‘theory is already widely debated in the world of physical literature, but it has been only in the past decade that researchers have shown that Tsallis’ mathematics more accurately describes power law behaviors in a wide range of phenomena, The turbulence of fluids to the fragments created in the collisions of high-energy particles.
Constantino Tsallis is a candidate for the Nobel of Physics and will attend the EBICC on EBICC da USP-SP-Brazil.
