  1. what does it all mean really?

    • It MAY mean that Canadians like their prime Ministers to have long tenures. (The Joe Clark interlude conceals Trudeau’s.)

      Happy New Year!

    What is the explanation for the almost universal infatuation with years that end in zero (and, a close second, five)?

  3. Pythagoras may have learned in the Underworld that tens and fives are easy to multiply.

    Happy New Year!

    Did the Greeks have a zero?

  5. The Babylonians had a numbering system with a base of 12 (IIRC which is not guaranteed). I am not sure why that translated into circles with 360 degrees, but it did, somehow.

    I wonder if we would do likewise (i.e. prefer dozens to tens) if we all had an extra finger on each hand, à la Anne Boleyn.
