| Feb 2, 2020 at 21:03 | comment | added | GiorgioP-DoomsdayClockIsAt-90 | @sanaris Yes I know. But where is the connection with Shannon's definition which is a definition based on probabilities, not on individual configurations? | |
| Feb 2, 2020 at 20:22 | comment | added | sanaris | We can have information as single record about exact coordinates of every atom of some body, written in memory of some virtual logical machine which does not consume energy (what is also impossible because as all machines it must consume energy to retrieve and change information according to Carnot theory). | |
| Feb 2, 2020 at 19:33 | comment | added | GiorgioP-DoomsdayClockIsAt-90 | @sanaris Still, it is difficult to make physics without relating things to an even partial definition. If one takes Shannon's definition of information and information entropy, it is not obvious the exact meaning of statements like "information is physical" or "information is conserved". I am not saying that they are false. Simply that they are not trivial consequences of Shannon's definition. If I am wrong, please give me a reference. | |
| Feb 2, 2020 at 19:24 | comment | added | sanaris | @GiorgioP if physics would get a single solvable definition, there would be no physics after it gets solved | |
| Feb 2, 2020 at 19:23 | comment | added | GiorgioP-DoomsdayClockIsAt-90 | Without an explicit definition of information any statement about it is void and unverifiable. | |
| Feb 2, 2020 at 19:09 | comment | added | PhyEnthusiast | how does entropy relate to information? Is entropy proportional to information? If so, where does excess information go, given that entropy increases for a closed system for irreversible processes? | |
