Some quotes (mostly mine) from the discussion on the everything list http://groups.google.com/group/everything-list/t/aea1a68dd8286d97 13.03.2012 01:43 Russell Standish: http://www.nature.com/news/the-unavoidable-cost-of-computation-revealed-1.10186 This about experimentally testing Landauer’s principle that computation has thermodynamic constraints. 13.03.2012 16:29 Evgenii Rudnyi: Thanks for the link. Yet, it is unclear to me what is exactly information and computation in this experiment. To be more precise, […]

From discussion on embryophysics http://groups.google.com/group/embryophysics/t/419d3c1fec30e3b5 29.02.2012 22:34 Steve McGrew: If the whole drive is filled with a maximally compressed portion of the Library of Congress, it would contain a collection of 0’s and 1’s with no detectable internal correlations. That is, it would be random according to all statistical measures. In order to describe the […]

In the modern scientific culture, the statement that the entropy and information are the same things is ubiquitous. For example the famous paper of Edwin T. Jaynes [1] according to Google Scholar [2] has been cited more than 5000 times. The list of books from Prof Gordon [3] about the deep relationship between entropy and […]

A list of books from Prof Gordon http://groups.google.com/group/embryophysics/msg/e9229530251b7d58 While I might agree with you on the misuse of “entropy” in biology, many people would disagree with you, as evidenced by the list of books below. Adami, C. & N.J. Cerf (1999). What information theory can tell us about quantum reality. In: Quantum Computing and Quantum […]

There was a thermodynamics related question on the everything-list http://groups.google.com/group/everything-list/msg/a7abc464f7392055 and my answer is below. I used to work in chemical thermodynamics for awhile and I give you the answer from such a viewpoint. As this is the area that I know, then my message will be a bit long and I guess it differs […]
