Here is an unconventional approach if via logical variables in stochastic concurrent logic programming: Timeless Histories <https://codicalist.wordpress.com/2019/10/15/timeless-histories/> 0. Given a single source S, a set of possible destinations Dj, j∈J, a set of possible histories historyi, i∈I (pictured as spacetime trajectories) from S to one of the Dj. 1. Each history has an evolving phase e*i*·θ(t), *i*=√(-1), where t runs from time leaving source to time arriving at destination. 2. Each history has a hidden (logical) variable* _W (for “weight”): historyi(_Wi,e*i*·θi(t)) 3. Each history is a “timeless” entity though (cf. *Timeless Reality*, Victor J. Stenger). There is no “preferred” time direction. 4. At each destination Dj, the phases of the histories historyi terminating at Dj are summed, the norm is taken, and the result is unified with _Wi. 5. At the source S, the weights _Wi determine a probability distribution on I: a single history is selected at the source. Conclusion: With timeless histories, the choice is made in the present (the time the histories leave the source) probabilistically from weights determined in the future (the times the histories reach their destinations). * Logical variables are distinguished here by a “_” prefix. Not only do they play a “hidden variable role, they introduce nonlocality into logical processes. cf. A histories perspective on characterizing quantum non-locality <https://iopscience.iop.org/article/10.1088/1367-2630/16/3/033033/pdf> ~~~~~~~~~~~ *The limits of my language mean the limits of my world.* ― Ludwig Wittgenstein <https://www.goodreads.com/quotes/8835123-the-limits-of-my-language-mean-the-limits-of-my> CLP (concurrent logic programming) and SCLP (stochastic CLP) might provide a new language of logical processes for physics — nature as written as “billions and billions” of (stochastic) processes. The logical variable would play a role as a hidden variable (a term mentioned in some quantum theory references) because its binding could allow one process to instantly “update” another process separated from it by either space or time (i.e., a program-linguistic analog of spacial or temporal nonlocality). There is no reason physics has to continue to be written in the mathematical language of a century ago when there are new languages today from the domain of programming. *Underneath the surface of the classical world lies the hidden births and deaths of quantal histories.* @philipthrift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
