Professor Kenneth Libbrecht at Caltech University is very interested in crystal growth and pattern formation in ice. So interested in fact, he went ahead and created this lovely website (last reviewed in the November 27, 2002 Scout Report) that documents the very wide, and very interesting world, of "snowflakes, snow crystals, and other ice phenomena.� First-time visitors should look over the "Snowflake Physics" section, which includes a snowflake primer, crystal faceting, and of course, a set of musings on that much-discussed question: "Is it really true that no two snowflakes are alike?� The site also contains a section on "Historic Snowflakes", which contains the thoughts and insights of Johannes Kepler, Rene Descartes and Robert Hooke (among others) on mysteries of snowflakes and snow crystals. The site is rounded out by clutch of snow activities, snowflake "hot spots", and a snowflake image for users" desktops.
