How the fuck do they know what's happening inside of living things? Particularly with neurochemistry. You've got, let's say, a working brain. It's full of juices. You've got a science lab. How do you go about separating which juices are which and determining how they behave in the living brain?

What kind of time traveling technology are we going to have in the future?

200 years ago the best way to view past events was through art, paintings, drawings, or written text.

In the present we all have smartphones that can record audio/video at any given moment giving us an exact copy of the present for viewing in the future. There is also youtube and other major databases of video/audio from the past that is an exact copy of reality at that given time and setting in the video.

What is coming in the future? Is it 10s of thousands of years from now, hundreds? We're clearly going to have something that is just as much of a mind blowing leap as paintings -> recorded video. Are we finally going to be able to communicate and interact with the past in real time?

There's always the possibility that a portal-type time machine will be invented. That's a time machine that allows you to travel back to the time that the machine was turned on. I think that's such an interesting possibility.

The movie Primer is about this type of machine, and I think it's the best time travel movie.


Maybe that's too far away, though.

I don't think a time machine as popular conceived would ever be possible, because of certain implications of Everett-interpretation quantum theory. (But I also think that's why the 'grandfather paradox', even Hawking's radiation version of it, aren't the actual reason time travel is impossible; besides, since when did the universe prevent something just because it would have a destructive consequence? There must be another reason.)

So, you go back in time, to an earlier evolution of spacetime that you previously passed through (nvm how you got there.) The picosecond you arrive, your presence will alter the evolution of dynamical systems on a quantum level, which will propagate to the macro level. Like, just the very first atom of your probe or whatever would cause one photon to veer off in a different direction; that's all it would take for you to suddenly be 'off-course' for the world-line you originally left. But it's not like you wouldn't be in a real world that would still continue to evolve from that point in time under natural laws, but nothing you did would ever affect the wordline you came from, just the evolution of the new universe you had arrived in, because you diverged from that reality the second one single fundamental particle began to evolve in a different way

(i.e. the world where you didn't appear back in time -- say, like our world, where no one showed up to Hawking's time traveler party -- is, from an information theoretic perspective, exactly like the world where some future humans do discover time travel and ultimately travel to that time period, but we will never get to that world; those time travelers just left their home universe, to seemingly disappear and be lost forever, those who sent them out wondering why their history books don't miraculously change, while those who receive them at the party wonder how the time travelers, who are now just a normal part of their universe, can continue to exist, since their arrival should surely disrupt the chain of events that leads to their creation? But in reality, they are just hopping between quantum realities, which are eternally separated from one another by whatev…

Those books are pretty old and a lot of the ingredients lists have either been put on lists or simply become less available/more expensive due to normal market reasons, such as decreased demand and production and industry standards leading to different choices. It's quite possible that where OP is, the specified list of requirements could be 10x what he actually needs for the synth.

First off I'm not a complete noob asking if adding hydrogen peroxide to kratom leaf makes 7-hydroxymitragynine.

I'm basically just wondering if it's even possible to extract 90%+ pure mitragynine from kratom. Would such a thing be possible without chromatography? Simple A/B then chloroform and then maybe specific solvents/PH?

I was gonna reply a week ago but it got deleted so I never did.

Picric acid is unnecessary, it's just for recrystalization which isn't necessary for my purposes.

I'd just evap the mitragynine hexane fraction to get freebase mitragynine or salt it with citric acid.

Maybe this is a dumb question. But I'm going on my annual wikipedia dive on nuclear disasters.

If they built all of these like 500m below the surface and covered in heavy rocks or concrete/steel wouldn't most of the effects of a total melt down be contained by the ground?

It seems like the worst part of a subterainian melt down vs one on the surface is there is probably a mini earth quake in the area.
But in my mind it seems most of the fallout and radiation would be contained, you only have to worry about ejected materials and chuncks i suppose?/
And as long as your reactor isnt near any fault lines i dont see any real danger.


Also after a melt down it seems itwould be much easier to fix the problem if its in a giant hole in the ground vs sitting in the middle of a russian village.

IDK, educate me internet.

Only way this happens is if the government requires it or specifically pays for one to be built underground. They aren't interested enough in the environment to spend extra money on that.

Also the other dude raises a good point that it really should not explode if you implement decent inspections/regulations and keep Homer Simpson out.

Still, they really should be built underground or something because when it does fuck up it's really bad

It's a more advanced technology that isn't as fully developed, so everything about it costs more. And, even if it were at the same economy of scale, an individual unit of fuel costs more, since it must be transmuted from thorium to uranium first. The only savings are in safety and waste concerns, and those are long term costs which people like to ignore in favor of short term ones.

This is just my understanding, I could be wrong. It seems mainly because were stuck with the old reactors because they cost so much to build that we more or less have to use the old ones for a long time until they've paid for them selves or outlived their usefullness or economic sustainability.

Then also the whole industry is standardized around the old technology. So to switch to a new one would be like a major format shift that the entire industry would need to adapt to, and it just costs too much money.
Also you would need to train a whole new generation of nuclear power plant operators on a new type of reacor. Where I imagine that most of the work is still on old reactors, why train for the new ones?

Power generation can't occur solely in one specific place. It's decentralized for a reason: power transmission is not an efficient process over massive amounts of distance. It's the same reason the old "why don't we just build massive solar arrays in the Sahara to power the world" trick won't work. It's not enough to generate the power, you have to wire it to the locations that consume power. Resistance, even for highly efficient conductors like copper wire, plays a big role in determining the power grid and its constituents.

I was looking up how to extract DMT and apparently it's most commonly done with Mimosa Hostilis root bark. Looking at the guides it's very MacGyver tier. I'm saying I'm wondering if there is a more professional way of doing it. Essentially I'm asking, if you ever looked into extracting DMT and if you have the chemistry background, what methods of extraction do you prefer/recommend and do you have any advice regarding it? Perhaps a mistake that commonly diminishes the quality of the extraction or some deviation from the existing guides to end up with something more pure.

Rotovaps make chemistry much, much, much easier. That's a device that evaporates solvents very quickly.

Solvent choice is also very helpful. The amateur has to choose between a few commonly available solvents meant for shit like paint-stripping. Professionals can choose a solvent that has analytical standards, and is harder to obtain (can't get at the hardware store).

Pros also have better filtration systems. This is less expensive than the rotovap, and not as much as a time save, but still very helpful.

TLC plates help keep track of whether or not product is there (so you can be more efficient when pulling).

Better ventilation is nice.

Lab freezers are better than home freezers, and usually have safeguards to prevent blowing up.

In the end, if you have white crystals, it's a reasonably pure product. Crystallization is cool like that. However, a well-stocked lab will get higher yields in less time.

TLC is most often distribution chromatography ( with a smidgeon of absorption chromatography) , meaning its more about polarity of the substances than about their weight itself (though there often is an indirect relation between weight to affinity). you basically have a solvation hull on your substrate and the mobile phase flows above that, depending on the polarity of a substance it moves between the stationary and the mobile phase, thus seperating from other substances. ive made a nice animation for that shit but im too paranoid, ill see if i find a comparable animation

in theory you should get one band per compound of your mixture but high concentrations or an unsuitable eluent may lead to streaking and improper seperation depending on the number of theoretical seperation stages.

in the OP scenario TLC would only serve as an analytic tool, even column chromatography couldnt really yield a lot of DMT doses

youd be seperating by molecular weight if the different compounds had no intrinsic dipoles. i used to hate chromatography since its such a bitch ass compromising bullshit way of seperation... wait theyre all based on equilibrium

you can do TLC on a large enough plate after plating it on glass and then chisel the silica or alumina off it to extract it back out

you can do that up to like 2g of a sample depending how many silica coats you do and how patient you are. works for analytic and organic chemistry. definitely not for others. but then again, if you're operating with fucking oxymorphone or dmt or cocaine for personal usage, this may be viable.
