Entropy, Volume 26, Issue 8

August 2024 - 103 articles

Cover Story: Well-designed experiments allow for conceivable alternatives of physical explanation to be distinguished. Experimental answers to physical questions emerge in the form of elementary observations (EO), which are binary pieces of information with a cognitive value of one bit and which become macroscopically observable by the dissipation of particle and instrumental resources of energy. As dynamical entities, EOs emerge through the four phases of initiation, detection, erasure and reset, requiring the input of at least two units of the Landauer minimum energy of ELa = ln(2)kBT per unit of entropy kB generated in the detection process. View this paper
