The principles of neopositivism and the laws of thermodynamics

Didier Lairez

The second law of thermodynamics, which deals with irreversibility and makes the theory so special, is usually considered empirical. The definition of equilibrium as an attractor,…

Disentangling Brillouin's negentropy law of information and Landauer's law on data erasure

Didier Lairez

The link between information and energy introduces the observer and their knowledge into the understanding of a fundamental quantity of physics. Two approaches compete to account f…

Energy and information: a chronicle of hesitations on the role of the observer in physics

Didier Lairez

Energy has no definition, except that given by a conservation principle which essentially amounts to defining it as the elements of an open list of unknown cardinality. Entropy, id…

The fundamental difference between logical and thermodynamic irreversibilities, or, Why Landauer's result cannot be a physical principle

Didier Lairez

Landauer's "principle" claims that erasing one bit of information necessarily dissipates at least Tln2 of heat into the surroundings, making a possibly logically irreversible opera…

On the supposed mass of entropy and that of information

D. Lairez

In the theory of special relativity, energy can be found in two forms: kinetic energy and rest mass. Potential energy of a body is actually stored under the form of rest mass, inte…

Thermostatistics, information, subjectivity, why is this association so disturbing?

D. Lairez

Although information theory resolves inconsistencies (known under the form of famous enigmas) of the traditional approach of thermostatistics, its place in the corresponding litera…
