Snowflakes are a good example of the fact that thermodynamic entropy isn't the same as "order" as perceived by humans. The snowflake has higher entropy (2nd law) than the water + air system that formed it, even though it looks far more organized. https://twitter.com/ZonePhysics/status/1160843941857648640 …

the total system of snowflake + environment has higher entropy, but the snowflake and its particles, seen as a system, are in a lower entropy state as the snowflake than not

think about it: there are way more ways to throw around H20 in general than to arrange them into a snowflake ==> snowflakes have lower entropy than fluids.

The 2nd law assumes equilibrium conditions. It can be violated in far from equilibrium conditions. Incidentally, these conditions is where order arises.

Local micro violation of 2nd law ... possible! Something I learned from
