How do we know that no snowflakes are the same?
I've nothing to offer on snow flakes. I will forever recall, not accurately, your analogy of a fighter prop planes speed and the photogs camera settings. It left a lasting impression on my simpleton mind. Looking back, thank you for that flashguy.quote:Originally posted by flashguy:

Given an eternity of time, one might suppose that 2 identical snowflakes could occur. (One thinks of the monkeys and typewriters.) Since a single snowflake is not likely to exceed a particular size, there is a finite (but enormous) limit on the number of possibilities how individual water molecules could add to the structure, so "never" the same is probably not provable. I suppose it is possible that 2 humans could randomly be created with the same DNA complement even when unrelated in any way, but that possibility does not impede use of DNA in genetic investigations.

I'm guessing you meant "analysis", not "analogy", but you're welcome in any case.quote:Originally posted by David Lee:I've nothing to offer on snow flakes.
