I don't know what exactly "emergent" means in this context, but doesn't ice appear pretty rapidly? It appears between -1 and 1 degrees, and when cooling down from 100 to 75 to 50 to 25 water you would learn nothing about the freezing point.
- throwaway290 2y agoEvery volume of water IRL will disagree about the rapidity though, go below 0 and first it's water, then it has some ice, then more ice, and only after a while eventually it's all ice (and even then maybe it has some water underneath, who knows). I can't see how it is not common sense. But with LLMs the common sense was until now "they can't then they suddenly can"
- RandomLensman 2y agoThe water usually isn't below 0 in those cases.
- throwaway290 2y agoMy thermometer says it's -5, yet water is liquid. To be more precise, covered with thin ice. And covered with (thicker) ice it shall stay all the way to -20 probably. Whatever technical correctness you throw doesn't matter to common sense logic. And that is even if there is a technical possibility to lower the temperature of every water molecule to -0.0001 simultaneously and demonstrate that it instantly freezes the entire volume in an instant. It'd be irrelevant since none of us live in that lab.
- RandomLensman 2y agoYour water is -5C? Is it salt water?
- throwaway290 2y agoThanks for another example!
- RandomLensman 2y agoFor what - that different liquids have different freezing points? Not sure anyone is doubting that.
- throwaway290 2y agoWhat are you arguing for exactly? That there may in theory exist some abstract spherical volume of perfect water in vacuum that freezes entirely in an instant that none of us will ever encounter in our lives? But that it is exactly what we should imagine when we think of how ice forms-- humanity's mental image should be of water instantly transforming into ice? Please clarify:)
- RandomLensman 2y agoIn a way - yes. Ice in nature forms usually by water cooling heterogeneously, but not by water being below 0 all the time and everywhere and the ice forming slowly in some areas then.
- throwaway290 2y agoNot just in nature, your glass of water in the freezer also has uneven temperature throughout the volume and becomes ice gradually (though faster than a lake)
- maxcoder4 2y agoClear water freezes exactly at 0 degrees. I guess the graduality depends on if you think about this as interpolating the water temperature, or interpolating the energy given/taken from a body of water.
- TeMPOraL 2y agoNot to mention, if water is pure and still enough, you can cool it below freezing point, and it still looks like a liquid, until it is disturbed and then it suddenly doesn't. Same with heating up above boiling point.
- lukan 2y agoAlso with heating? So all the bubbles rising up way before boiling and the visible evaporation does not happen with distilled water? Hard to believe, I have to say. You would have to do perfect even heating of all the water, to stop the movement from different temperate areas. Microwaving it?

- lukan 2y agoThx. And maybe not the best idea, but now I want to try this ..
- hkt 2y ago> maybe not the best idea, but now I want to try this .. I'm going to steal this for my epitaph, thanks
- lukan 2y agoHave fun with it. Mine would currently say: Por tu culpa! (this is all your fault) But depending on the circumstances, I would be also fine with the one above. But very likely I would not care that much anymore ..
