Need some help guys. So for ???? reasons I'm making a program that models geological systems and mineral formation. Does anyone know of a good source of information on the crustal prevalence of various minerals? I obviously can't simulate every mineral known to science, but I want to get an appropriate swath.

Much appreshes.

NVM. It's still very general, and not really saying what the minerals are. But when you google for "minerals" you pretty much only get exploitable minerals.

I'll stop posting now.

Wow that's a fuckin cool link you found. Unless there's the same data somewhere in table form it's not very useful to me, but I'll probably be dicking around with it anyway, very interesting stuff.

>> You just want to know the total % of minerals, but not the geographical distribution?
Yes, then once I have percentages enough to single out the most significant minerals and soil types (scientifically significant, rather than economically) I will very crudely model what conditions cause the transformations between the different types (elemental composition, heat, pressure, water content, etc.) in order to spit out a world map that is geophysically earth-like but not the actual world If you must know, it's a map generator for a game

>>you pretty much only get exploitable minerals
Yeah that was my frustration which is why I came here in the first place. All lists are either popular/business ones that only list exploitables, or really minor geological papers that go into great minutae about some mineral that only exists in this one crater in BFE. But just by gumshoeing through that I was able to come up with a reasonable middle between the two. 'Rock-forming minerals' was the keyword that seemed to work best for me.

Anywho, thanks for the help guys. I guess we can keep talking about minerals because they are pretty rad, otherwise I will necrobump this thread if it hasn't fallen off by the time my generator is working and show you guys.

Ah thanks but no, those guys are notoriously tight lipped and the complexity of Dwarf Fortress is far beyond the pale of what is necessary or would even be functional for my purposes. Besides, at this point Dwarf Fortress is well studied within the gamedev community and it's easy to get references about how it works without having to bother those two guys.

Definitely though what I am working on has some broad similarities in terms of making a world simulation that leans on emergent properties, but I'm basing it on real world science and chemistry rather than fantasy. Instead of 'mine 5 generic shits and 5 dire poops to craft 1 epic turd' it will be 'collect 75 kg water, 25 kg bacteria, 5 kg protein and 20 kg sugar to make 100 kg of epic turd'

Right after reading your post, I came across this: https://features.weather.com/exodus/about/ . It's about the current/coming mass migrations due to climate change.

>Are there any viable solutions?
We're on the verge of crossing the point where geoengineering is the only viable solution. However, nobody really wants to do this because of how risky it is. There's always unforseen consequences, and if you're trying to engineer the global climate, who the hell knows what could go wrong. https://en.wikipedia.org/wiki/Climate_engineering

You could try being optimistic, like: after Trump is gone, america will come to its senses and take the lead in combatting climate change... But that's obviously not gonna happen. About half our population will fight any action on climate change, no matter what.

>>How fucked are we?
Moderately fucked, but it depends on your definition of fucking. Certainly, the world will change. Almost inevitably, some parts of the earth that are now habitable won't be. There may be food crises, but that might be offset by a greening north (most of earth's land mass is in the northern hemisphere.) There will almost certainly be water crises unless we can improve desalination technology and fast.

However, unless in the process of that we start going crazy (as we are liable to do) nothing about that is an existential threat to our species. We would survive it...however, 90% of animal species probably wouldn't. I imagine the 22nd century will be kinda like the world of Blade Runner...animals and forests are something you read about in books and museums, while almost all available space is converted to high tech farms to eke out enough calories to feed the planet using the few remaining (probably insect) species for food.

Alternatively, the AI may take over during this century and put an end to all this nonsense before that can happen. That's our actual best case scenario.

concerning the synthesis
this is some pretty whack shit. you can even synth superphane but this would be way too much strain on the sp2 carbons of the benzene.

theoretically speaking its an 5-amino anhydride derivative of isophthalic acid, my best guess is that its an exercise aimed at the nomenclature or bicyclocompounds or rather heterocycles.

could you double check if you got that structure right?

  • you can't put an anhydride and an unsubstituted amine in the same molecule
  • you can't link meta-separated benzene substituents unless you make an 8-or-more membered ring, because otherwise you're violating bredt's rule

that said, the compound you've drawn could be called 3-amino-6,8-dioxo-7-oxabicyclo[3.3.1]nona-1,3,9-triene. but it is impossible.

it's been a milltion years since i've done a CWE and there's one question i have in regards to the amoung of water to be used.

i understand that there is always going to be a little Acetaminophen in the final solution. however, codeine phosphate being as soluble in cold water, or just plain water, as it is i was wondering wether you could skip the whole freezing part of the procedure and instead use a small amount of water. where would potential problems be? i can imagine it would take a really long time as the water would have problems penetrating through the sludge of filter and Paracetamol. but apart from that why could this be a bad idea?

Sup /chem/,

There is a fundamental gap in my understanding of the universe. When we look out into the sky and see the sun and stars, measure the Earth orbiting the sun, or see a volcano, it is commonly accepted that eventually, all of these processes will run out of energy and cease to do their thing. However every atom in the universe has positive and negative charges, with the negatively charged particles constantly in motion (and i guess the positive ones too if we count vibration or whatever). How do subatomic particles get a charge in the first place? Will it ever wear off? What makes electrons move? Will an electron ever stop moving and become neutrally charged? Can we apply this seemingly infinite source of subatomic energy to the macro scale to prevent a big freeze or one day generate limitless energy?

Does anyone please know of a general way to determine if there's any local max and min *within a set range of X-coordinates*?

As we can see, there's a local max somwhere around -1 and a local min somwhere around 3 and none whatsoever in the range 1-2.

But how do I prove that there's no local max nor min in that range?

I'm looking for *local* max/min in trig-functions. I know that if the x-range is long enough, there will be *many* local max/min.

For instance this function has local max/min all over the place and repeats itself every 3600 x:

f(x) = sin x(sin (x/10))

I know there's a local max between x(1500) and x(1530). But how do I prove it by doing a f'(x) for only that range?

I think it still works the same way. Take derivative. Set equal to 0. Solve within your range. That's a lot of trig functions to fuckin deal with. Here's wolfram alpha's solutions:


Solutions are at the bottom. Hit the 'exact solutions' to see what kinda algebra is needed for that function. So obviously the way to do this is numerically. Look at the original function

Then look at the approximate solutions in the last page. You can see that the local maximum for that range is at:
For which the function returns: 0.987810970335936684937

Or, in one easy step: https://www.wolframalpha.com/input/?i=maximum+sin(x)(sin(x%2F10)),+1500%3Cx%3C1530

Maybe that's cheating, but fuck trying to analytically solve that.

the fact that youve posted that is further evidence of the genius of the idea to establish a /shill board. naw just kidding.

concerning the analytic component of the question, im kinda ashamed it took me this long to think of, you could take the derivative via product rule (not sure if another approach would deliver something more moldable) and then reason examine the zero points of the derivative and second derivative.

im a bit confused as to what the actual function is, should it - as mentioned before - be y= sin(x) sin(1/10), the derivative itself will be a sum of two periodic products, meaning youd have to evaluate cases where either both terms are zero or one term is the negative of the other. depending on the range the answer should be given in multiples of some fraction of pi (kirt, tex support when)

during my analytics classes giving a numeric answer was a telltale sign of misunderstanding the task

And should your task be to prove that the function has a local min/max on a given closed range you could simply show that the function is continous (as a composition of continous functions) and then a local min/max has to exist.
