Sorry if this is a stupid question, I don't fully understand entropy. Snow flakes are highly structured, they form from water vapor which has very little structure. I must be misunderstanding entropy, my interpretation of it is that isolated system must evolve into more chaotic less structured states, which is not what happens with snow flakes. Can someone explain? Also another question. Mods if you feel this is pseudoscience please just delete this paragraph instead of my whole thread. Does free will necessarily violate law of entropy? Because when I decide to raise my arm, something to switch on by itself in my brain and send electric signal to my arm, seemingly with no external influence. Again this must be my misunderstanding of entropy.
