In 1871, in this book called ''Theory of Heat'', Maxwell speculated the idea of ''a being, who can see the individual molecules'' and who has enough reactive intelligence to open and close a unique small hole existing between two communicating vessels (called 'A' and 'B'). An ideal gas filled both vessels, so that starting at uniform temperature the intelligent being could observe the molecules and close and open the hole accordingly to a mission: ''to allow only the swifter molecules to pass from A to B, and only the slower ones pass from B to A.'' The being, ''without expenditure of work raise the temperature of B and lower that of A in contradiction to the second law of thermodynamics.'' The ability of the ''being'' to use observable information about the system to lower the thermodynamical entropy has motivated many articles in physics and fuelled the imagination of many since it was originally introduced by Mawell, and named as ''demon'' by Thomson three years later [622] . An excellent collection of articles until 1990 [634, 635, 636, 637, 638, 639, 640, 641, 642, 643, 644] was edited by Leff and Rex [645] . The Maxwell ''demon'', far from being ''exorcised'' from Physics, still inspires interesting new perspectives [634,635,636,637,638,639,640,641,642,643,644,646,647 ].
