Snowflakes-Cold beauty
Ken Libbrect, the chairman of the Caltech physics department says watching snowflakes can be a most rewarding winter pastime.
He recently put his accumulated snowflake science and lore into a coffee-table size guidebook, "The Snowflake:Winter's Secret Beauty." He hopes this will produce legions of new snowflake watchers.
"I should hardly admire them more if real stars fell and lodged on my coat." -Henry David Thoreau 1856
