| summary | The major observables in Physics are largely, if not exclusively, based on or derived from energy (conservation properties as symmetries, geodetic principles as least action principles...). Biology forced us to think in the novel terms of “organization” and, even, of inherited organization; an organization whose “complexity” grows along evolution and embryogenesis, against energy degradation in Physics (entropy production, also in non-isolated systems).
Then, with World War II, the age of coding, decoding and information started. Informatics, Information Theory and Cryptography became well defined scientific displines, with their own principles and remarkable applications. Can we borrow for the analysis of life phenomena any relevant principle or precise result from these scientific areas? A critique of the abuse of Information in Biology will be hinted.
Some recent work will be introduced on a quantification of “biological (phenotypic) organization” by a proper observable to Biology, anti-entropy. The idea will be derived by conceptual dualities w. r. to Quantum Physics, where the operatorial approach by Schrödinger to his famous equation will (“dually”) guide us towards an equational modelling of Gould’s analysis of “phenotypic complexity” along Darwin’s Evolution and, if time allows, to some applications to embryogenesis. |
