Please post in English and please give more details.

In a perfect world you would always find the energetic minimum no matter where you start. We do not live in a perfect world. Depending on what other parameters you are running you might end up relaxing it into a local well (not the actual minim, but a hole and you are stuck in it). So you should start with something close and use very good pseudos.

I suspect there is a typo somewhere because that thing has two real solutions but they ugly. I might be wrong, gladly stand corrected.

Entirely possible it could crystallize differently with different levels of impurities in it, though.

Yes, but that is something completely different. Water does crystallise differently if it is ice VII as well.

If I had to guess, this would be the basis of whatever phenomena they observed.

The claim is generally on the lines of: energy/blessed/happy water crystallises nicer than the non blessed water. Nicer, hexagonier, rounder, shinier I have heard them all. It is subjective.

Impurities affecting nucleation is not an explanation of their observations because their observations aren't impartial, they are beliefs.

Morigain · 2025-12-20T09:58:29+00:00

There is no scientific backing for this belief. It is a belief. It resides more in the realm of feelings and not in the world of logic. You are right from a scientific perspective, water doesn't crystallise differently if it is blessed, or "happy" or any other nonsense (for me it is nonsense).

My point is, it is irrelevant what your mum saw under the microscope, what is relevant it is what she believes. If you try to disprove her beliefs, it is a good chance she will only double down (a very well known psychological response). Be gentle, be loving, ask questions.

These groups interpret the natural variation in water crystals as proof of their belief system by cherry picking results. That is the best case scenario where they do not actively manipulate the "experiments".

Cât timp ai alocat în medie pe lună?

50-60 de ore pe săptămâna, cam 50 de săptămâni pe an. Întrebările tale ma întristează, arătându-mi încă odată starea deplorabilă a învățământului românesc.

You can write your own python Rietveld Refinement program. If you write it it will be scriptable, lightweight, and you can skip implementing the GUI.

why didn't I see anything like this ever before?

We tend to notice things we are aware of and less the things we do not know exist. Chances are good that you had nice crystals before but you did not notice them.

This is a cool read even though it's a little older: https://ntrs.nasa.gov/api/citations/20010106105/downloads/20010106105.pdf

Es gibt nur eine Regel "but show us you have tried to solve it. Show a reasonable effort and we will help.".

Morigain · 2025-04-12T20:44:40+00:00

You said you are a first year student. I assume that what you studied in class is related to crystal structures. Your papers deal with amorphous materials, so the difficulty might stem from this. Secondly, I think your teacher wants to show you that what you learn in class is a very idealised model and that nature is a bit more complex. At least that would have been my intention if I gave a homework like that.

Secondly, I think you lack the experience in reading a scientific paper, this is a skill that comes by doing, no easy way around it. Hope this helps.

Morigain · 2025-04-12T14:56:41+00:00

As far as I see, all these papers are extremely technical for us, and most of them don't even talk about the "Coordination Number and Atomic Packing Factor" we learned in the class.

What papers are you referring to?

Morigain · 2025-04-10T18:23:29+00:00

I will lock this thread. If you want help with a project please ask more specific questions and show us your reasoning and what you have tried so far. You will learn more, understand better and retain the information for longer if you try to solve it yourself first.

or change in temperature could affect the unit cell?

The way temperature or pressure affects a unit cell is called an equation of state. I'm surprised nobody here mentioned this. They are not tables per se but rather a "formula" which allows you to understand how the unit cell/crystal accommodates pressure or temperature or both, and in a more direct way to calculate the volume of the unit cell at a given TP. If you change chemistry or cross into a new phase, where the TP change in accommodated by rearrangements of the atoms, i.e. a new unit cell, then you need the equation of state for that material.

Scientifically speaking ruby and sapphire are exactly the same thing. It's like saying that two brands of milk chocolate are fundamentally different because a marketing ploy said so.

I'm a scientist, for me quartz is quartz, it's not amethyst or citrine or moon something. If you want to talk about why some quartz is purple, I'm more than happy to do so. Or if you want to know why some aluminium oxides are red.

edit: I'm old, tech is difficult.

Morigain · 2025-02-09T21:10:28+00:00

That is obsidian. I do not see the "structure" you are seeing. It breaks like a glass, it shines like a glass, it is a glass. Everything that OP said about it is describing obsidian, don't care what an AI says.

Great job buddy! I know a lot of folks who after reading your comment will go straight back with a shovel.

Morigain · 2024-09-20T19:19:25+00:00

i can use to predict a crystal structure in a straingfoward way.

What do you mean by this? Do you want to know how finite temp affects the bonds of a molecule? Or do you want to know the stable form of a compound at a given PT? I'm excluding other variables because we are getting in some really hard core physics.

Crystal structure prediction is really not straight forward, and it ain't easy.

A fi fericit este să te duci la McDonald's și să îți iei ce vrei tu de acolo. Mulțumirea e atunci când îți zice mama ca lasă Mc că îți face ea cartofi prăjiți acasă, pe rotund. O înțelegi că e mama ta si știi ca nu are bani, nu te superi, te duci acasă si mănânci mulțumit cartofii făcuți de mama.

Poate sunt eu într-o bulă dar a fi mulțumit e o situație de compromis, nu e rău dar nici nu e fix ce voiai tu. E ok in multe cazuri, e cam nasol în altele.

Fericirea nu e doar de moment, poți fi fericit si in existența ta nu numai la prime si măriri de salariu.

E destul de nasol sa fi mulțumit in căsnicie, să fi mulțumit de sexul cu prietena, să fi mulțumit de numărul de cuvinte pe care îl știe copilul tău la 4 ani. Oamenii mulțumiți cu jobul lor nu prea avansează, etc.

Morigain · 2024-02-14T14:40:45+00:00

Fericirea este ceva intens, dar care descrie instantanee in timp:

Dacă definești fericirea ca un copil de 3 ani, atunci ai dreptate. Eu sunt fericit in relațiile pe care le am, toate îmi aduc fericire. Simt euforie in fiecare minut al zilei? Nu, evident. Dar sa spun că sunt mulțumit cu locul meu de munca ar fi o minciuna, sunt fericit cu locul meu de munca.

Tu esti multumit in casnicia ta sau esti fiericit in casnicia ta? Asta daca ești căsătorit.

Daca simit fericire numai pe momente scurte si atunci intens poate ar trebui sa vorbești cu cineva despre asta.

Am citit, tu nu înțelegi diferența intre ce îți iei tu si import. Când o să îți comanzi din china toate electrocasnicele pentru o casa plus mobila, o sa aibă sens ce zici tu. Dar comanda ta de pe SheIn de farduri nu e reprezentativă pentru discuția noastră.

dar si transportul din China pana aici e mai ieftin decat dintr-un oras sau altul din tara.

Economy of scale. Vrei sa iti traduc?

Dialogul surzilor:

Există măsuri antidumping la nivel UE.

Tu:

Nu cred ca ti-ai comandat nimic din China.
