Joe Hanson takes a look at the science of snowflakes. The origin of no two snowflakes being alike comes from Wilson Bentley in 1885. He's right (but for the wrong reasons).
Snowflakes are symmetrical but they're not perfect. They are ordered but they are created in disorder. Every random branch retells their history, that singular journey they took to get here. And most of all they are fleeting and temporary. Even if sometimes they don't look so unique on the outside, if we look within we can see that they are truly unique after all.
