My favorite part of winter is a gentle snowstorm! I love to stand very still and watch the flakes fall around me. My black wool coat makes a great backdrop against which to observe the delicate symmetry of the flakes. While each flake IS unique, their formation does follow a very specific and scientific pattern. A snowflake is just one of many fractals found in nature. A fractal is a complex geometric pattern in which small details of its structure, viewed at any scale, repeat elements of the overall pattern. This video is a great verbal and visual depiction of the science behind snow! Here's hoping we can make many scientifc observaiton of snow this winter. Let it snow, let it snow, oh please let it snow.
