cyberspittle sends this excerpt from Scientific American: Tentative new work ... suggests that perhaps the arrow of time doesn't really require a fine-tuned, low-entropy initial state at all but is instead the inevitable product of the fundamental laws of physics. Barbour and his colleagues argue that it is gravity, rather than thermodynamics, that draws the bowstring to let time's arrow fly. Their findings were published in October in Physical Review Letters.

    For those interested in time travel, the inaugural meeting of the International Time Travel Association will be held at the Perimeter Institute last Tuesday at 20:00.
    The meeting location will be posted next Wednesday.

      Boring. I might head there next week-end if I can bother, or maybe the one after. Time travel means I can procrastinate indefinitely.

      The guest speaker was half dead from temporal lag and the symposium got over scheduled, twice!
      Don't even ask about the Parallelers. Ack!

    I *refuse* to read science articles unless they are dumbed down, explained with barely-relevant images, and posted on medium.com!
