Tribus

Jayne's paper was of considerable influence to American engineer Myron Tribus who had spent the previous ten years attempting a similar derivation that when in 1948 he was told about Jaynes' paper he took an overnight train from LA to Stanford to visit Jaynes in his office. [5]

Economic thermodynamics

In 1991, Jaynes initiated a foray into economic thermodynamics with his article “How Should we Use Entropy in Economics: Some Half-baked Ideas in Need of Criticism”, the subtitle a pun on Paul Samuelson’s 1972 “half-baked” comment, in which is he introduces some tentative outlines of how an economic system can be modeled as a thermodynamic system, such as how Willard Gibbs' 1873

where (X,Y,Z ...) are some type of macroeconomic variables, which he doesn't really go into, and W is the multiplicity factor of the macroeconomic state, which he describes as the "number of different microeconomic ways in which it can be realized", whatever that means, and tries to connected in some way to French mathematician

Education

Jaynes received his BA in physics from the University of Iowa in 1942 and PhD on ferroelectricity at Princeton in 1950 under the direction of Eugene Wigner. [3]

**Edwin Jaynes**(1922-1998) (CR:40) was an American physicist noted, in information thermodynamics, for his maximum entropy (MaxEnt) interpretation of thermodynamics, as found in his two part 1957 paper “Information Theory and Statistical Thermodynamics”, in which he attempted to derive a statistical thermodynamics interpretation of information theory. [1] Jaynes’ approach, in terms of schools of thermodynamics, soon came to be known as the MaxEnt school of thermodynamics also sometimes called the Jaynes school. Into the 2000s, Jaynes' MaxEnt formulation of nonequilibrium statistical thermodynamics, however, has generally failed to be accepted by the majority of scientists. [2] In about 1965, Jaynes wrote the outline of a thermodynamics textbook, that was never published. [4]Tribus
