How can they say that no two snowflakes are identical?
Something to consider is what is the definition of identical. Is it they look alike, they are identical to the molecular level, to the quantum level. As many snowflakes that have fallen, it may seem like there must be some identical flakes, but remember that they is a nuclease that is composed of a bit of windborne debris in each snowflake – an ash, smoke or dust particle. For every bit of this to be identical to the quantum level probably has never happened nor will it.
