FRAGMENT FROM NATURE deals with snowflakes. A snowflake is not a glacier, but both are made of ice. Yesterday evening I stood on the magnificent Charles Bridge in Prague, where Kepler in 1610 (a mere 406 years ago) on this very bridge had a snowflake alight on his coat and launched him into a treatise on the six-fold symmetry of snowflakes published a year later. A salute across time to this magnificent thinker.
