Uniqueness[edit]
Almost all snowflakes are unique. This snowflake shows typical asymmetries that make snowflakes so diverse in form.
Snowflakes form in a wide variety of intricate shapes, leading to the popular expression that "no two are alike". Although nearly-identical snowflakes can exist, they are very unlikely to be found in nature.[7][12][13] Initial attempts to find identical snowflakes by photographing thousands of them with a microscope from 1885 onward by Wilson Alwyn Bentley found the wide variety of snowflakes we know about today. In 1988, Nancy Knight was documenting snowflakes for the National Center for Atmospheric Research and found two identical snowflakes of the hollow column type. It can have many sides from 5-(a number on beyond)[14
