I Didn’t Learn It on a Blog, but in a Book

Earth’s rotation is slowing, lengthening the day by 2.3 milliseconds “per day per century,” due to “tidal friction.”


  1. I thought the days were getting longer, glad to know I wasn’t just getting older ;)

    Somewhat related, although I’m no expert, is that the Earth’s molten Iron core is gradually getting colder and when it ceases to be molten, we end up like Mars. No magnetic field. I’ll probably be dead by then so no worries there.

    Speaking of reading a book, I’m reading L. Frank Baum’s, “The Wonderful Wizard of Oz”, and am liking it. Seen the movie a zillion times, (including on the big screen), but the book is cool, might well read a few of his sequels.

  2. I have never heard of that. Cool thing to think about. Better than thinking about the news and the newsmakers.

    Wonder how much friction it would cause if we all threw our shoes at the same time? Lots of good targets out there, and few of them would have Bush’s blessedly quick reaction time.

    Would it be called a shoe in? Or a shoe out?
