Constructor Theory, Module 2: Irreversibility

As we saw in Module One, all dynamical laws of motion are time-reversal symmetric: if the trajectory of a system from state A to state B is allowed by particular laws of motion, then the trajectory of that system from state B to state A is also allowed by those same laws.   Yet this fundamental reversibility sits in stark tension with the one-way processes we observe all around us.   Since 1870, a number of attempted solutions to this conflict have been offered that can’t quite solve the problem. But, as is often the case in science, understanding the reasons why they fail shed light on what attributes the actual solution must have.   Read: https://conjectureinstitute.org/courses/constructor-theory/Constructor%20Theory%20Module%202.pdf   Visit Conjecture Institute: https://www.conjectureinstitute.org/   Donate to Conjecture Institute: https://www.every.org/conjecture-institute-inc#/donate/card   Follow Conjecture Institute on X: https://x.com/ConjectureInst
