Even though it’s been warm here in the Southeast, winter is not yet over.  To remind us, NPR has a fascinating video on the growth of snowflakes available as their Valentine’s Day gift to us.  It is about two minutes long and features the slow growth of dendrites, which are the typical snowflakes you see drawn by kids and in Christmas displays.  You can view it at https://www.npr.org/sections/13.7/2017/02/14/515154626/video-making-snowflakes-in-slo-mo.
