I took a quick look at a newstand copy of "American Scientist," the current issue. A good article on variations in the cosmic background and how this might be able to give some indications about very early "forks" taken in the evolution of the universe we are in.
In other news, am reading Graham Priest's "An Introduction to Non-Classical Logic," 2001. A good survey of various kinds of modal logic, multi-valued logic, intuitionistic logic, etc. I also found an interesting book by Robert Goldblatt, "Mathematics of Modality," 1993, which contains a paper "Diodorean Modality in Minkowski Spacetime." He points out that Arthur Prior, in books from the late 60s, early 70s, demonstrated that the lattice of partially-ordered events in Minkowski spacetime corresponds to a modal logic system called "S4.2." (Sidenote: Bruno uses these names for axiom systems more comfortably than I can at this point. Just citing a name for some system is not very convincing to me, without having the background to know what the names imply.) The point is that apparently my hunch about time being viewed as a poset, which I wrote about several weeks ago, is already known to people like Goldblatt and Prior. This remains my focus. --Tim is a Democrat, as he is always looking for a handout" --Unknown Usenet Poster
