It is to-day a widespread opinion that entropy (in its thermodynamical sense) and information (in Shannon’s one) are closely related notions (or quantities). As is known, the idea was first initiated by L. Szilard[l] as early as 1929, resumed in 1931 by J. Von Neumann[2] in his treatise about Quantum Mechanics, and it was resumed again and more broadly developed by L. Bri11ouin[3] in 1956 after the publication of the work of C.E. Shannon[4].
