"danR This nicely puts what has been a problem for me: we've imbedded motion in a static 4-space geometry. Why should particles 'simply start following' the geodesics...? What does 'following' mean? Is it simply a description of the necessary direction of entropy? But isn't entropy in this...

When members post photos for the contests, they sometimes have a small snippet/phrase which helps put their photo in context. I feel when a new voting thread is opened, these snippets might be placed along with the photo, if we voters don't remember what the picture was about when we saw the...
