`Thanks for the answer. My question was due to the fact that comp`

`presumably can simulate more than we observe. Let me check if I have`

`understood your answer correctly. I will cite a paragraph from my text`

`We bring a glass of hot water in the room and leave it there. Eventually`

`the temperature of the water will be equal to the ambient temperature.`

`In classical thermodynamics, this process is considered as irreversible,`

`that is, the Second Law forbids that the temperature in the glass will`

`be hot again spontaneously. It is in complete agreement with our`

`experience, so one would expect the same from statistical mechanics.`

`However there the entropy has some statistical meaning and there is a`

`nonzero chance that the water will be hot again. Moreover, there is a`

`theorem (PoincarĂ© recurrence) that states that if we wait long enough`

`then the temperature of the glass must be hot again. No doubt, the`

`chances are very small and time to wait is very long, in a way this is`

`negligible. Some people are happy with such statistical explanation,`

`some not.`

`Have you meant that the Universal Dovetailer will act for such a`

`situation according to PoincarĂ© recurrence?`

You can simulate it. But you cannot program it. It uses a huge amount of information that it is hard to extract from the environment. I would say. In a larger sense, in which we are ourself Maxwell demon, you can filter it from long computation. They will transform selective information into energy. they will economize. The Universal Dovetailer does generate all possible Maxwell daemons, but I guess they are typically distributed sparsely in the set of all computations. Quantum Maxwell demon? That might explains the origin of life, but that might be a too cheap explanation. I should revised quantum information theory, but I have already hardly the time to do the real thing, which is to extract the quantum information from classical information + self-duplication and other self-perturbation (or to convince others to do the work, or that such a work has to be done to get both the qualia and the quanta). Interesting but hard question. Bruno On 15 Jan 2011, at 18:22, Evgenii Rudnyi wrote:I am trying to understand what the hypothesis comp is about. It would be interesting to understand whether the Maxwell demon could be simulated or not. Any idea?
