Happy 11-11-11!  I bought a science-based book on calendrics back when the whole Y2K thing caught the public imagination. (Stephen Jay Gould’s ‘Questioning The Millennium‘)  And now with people being silly about the Rapture, the end of the world. and the Mayan calendar, I’m surprised that no one thought that something nasty would be happening today, what with the date being all ones (at least, the way it’s generally written… in this culture… at the moment.) Of course, that leads to lots of issues about whether the calendar we’ve chosen for ourselves has numbers on it that mean anything to the stars and planets of the rest of the universe, and whether Australia is gonna catch the &%$#  before we do, ’cause it’s tomorrow there already, isn’t it?
