“No process can result in a net gain of information” underlies 2LoT
Further to Granville Sewell‘s work on the 2nd Law in an open system, here is Duncan & Semura profound insight into how loss of information is the foundation for the 2nd Law of Thermodynamics. This appears foundational to the understanding and development and testing of origin theories and consequent change in physical and biotic systems. ———————
The key insight here is that when one attempts to derive the second law without any reference to information, a step which can be described as information loss always makes its way into the derivation by some sleight of hand. An information-losing approximation is necessary, and adds essentially new physics into the model which is outside the realm of energy dynamics.
