“Lives are snowflakes – unique in detail, forming patterns we have seen before, but as like one another as peas in a pod (and have you ever looked at peas in a pod? I mean, really looked at them? There’s not a chance you’d mistake one for another, after a minute’s close inspection.)” -Neil Gaiman
From a scientific perspective, is that true? What gives snowflakes their intricate structures, and what does it truly mean for a snowflake to be unique? Do we require the exact same branching structure? Can we obtain that if we create them artificially? Do we require identical-ness down to a molecular or atomic level? And how much snow would we need for that to happen?
