420chan is Getting Overhauled - Changelog/Bug Report/Request Thread (Updated March 22)

I started a thread on /spooky/ asking for any evidence of the paranormal or supernatural.

Instead all I got was a bunch of personal attack and people babbling nonsense and presenting it as truth. Then when shown they are incorrect with verifiable data rather than pseudoscience they resort to personal attacks again. They and pretty much all other magical thinkers take any sort of challenge to their beliefs as a personal attack.

I was at a party a few months back and some girl was talking about how she went to some yoga guy who does "laying on of hands". Which involves doing yoga while a dude puts his hands on your body and makes weird noises. Supposedly doing this achieves any number of effects from healing wounds, curing depression and other supposed boons.
not arguing the therapeutic effects of yoga just the laying on of hands part
I tried to understand what she was explaining to me by asking questions. Like asking her what was actually happening because it made 0 sense to me. Instead she started insulting me for being closed minded and shit.

Also in real life I live in the US south. Where people who think the world is 6000 years old is the norm.

Needless to say I deal with people who use magical thinking on a regular basis.
They are 100% willing to reap the benefits of science and the technology that comes with it until it conflicts with some myth or story about ghosts or some shit some one told them. Then all reason and logic go out the window.

Why do so many people especially in the us reject verifiable facts over what feels good? I went to the same public schools as them, I was also raised in a religious household (jewish, although I'm no longer religious). The only difference is that I chose the rational answer.

>>Its more appropriate to just say "indicates" or "we hypothesize".
Didn't read the thread so don't know if anyone has already mentioned this, but you should look into something called 'English Prime.'

Basically it takes the concept of the Sapir-Whorf hypothesis (that language creates mental state, that ideas possible to be expressed within a language are the borders of the space in which speakers of that language can have ideas at all) and uses it to attempt to fix English by making it more explicitly scientific.

For example, it removes almost all constructions of 'to be' including 'is' and 'are.' Nothing is good, or bad, or blue, or fast, but can seem, or appear, or correlate to those properties. It basically forces people to remove the unscientific and unprovable but completely common habit of claiming things 'are' things, reducing it to the simple truth; that they seem to be things, and deliberately denying the power to speculate beyond to 'the thing in itself.'

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?

Yes, but all are much more complicated than a reagent kit and if you can't buy or use a reagent kit you won't be able to do those. Things like melting point measurement, x-ray diffraction, GC/MS, MS/MS, HPLC/MS, IR spectroscopy, UV-VIS spectroscopy, NMR spectroscopy, conductometrics, gel-electrophoresis, etc. Just buy a fuggin reagent, or make it yourself: 4% of concentrated formaldehide, 96% of concentrated sulfuric acid. I heard in USA you can buy cc. H2SO4 as drain cleaner/declogger. Formaldehide is sold in the pharmacy. Mix it slowly while cooling, allow it to sit a few hours than drop a drop on a little piece of your X, if it turns purple it's something containing the methylenedioxy moeity, and since almost all possible drugs containing it are illegal now, why would someone bother making something like MBDB or Methylone or etc when he can make MDMA easier, cheaper and just as illegally.

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?

Graphene is very interesting nanomaterial for me. I heard that grapheneis widespread and used in electronic. It has next characteristics Carbon > 99, 6%, Thickness (nm): < 3.0 , MB surface area (m2/g): ~80, Density (kg/m3): 2,2, Bulk density (kg/m3): 120, Electrical resistivity (Q.cm-1): < 0.15. I think you need to find graphene in special laboratories like it http://mstnano.com/products/graphene/

>>How do you go about separating which juices are which and determining how they behave in the living brain?
It takes a really long time and a lot of work and most of the time you will be wrong or overly simplistic in your interpretation of what is going on. Serotonin for example was so named because they believed at first its primary function was modulating the consistency of blood serum.
For the specifics though, the way they tell which neurotransmitters affect what is by looking for ligand receptors at the synapse. The neurotransmitter works by being a 'key' for a specific molecular lock on the receiving cell, which initiates its action potential to propagate a shifting ion gradient through the dendrite. Then, they follow the trail of that neuron chain's axons until they get to something that's a muscle or sensory cluster (or backwards, to a specific region of the brain) and then end up saying something like 'these neurons are part of a pathway connecting this behavior/sensation to control from this brain region, modulated by this neurotransmitter.' If you noticed this is not much different than the room of blind men describing an elephant by grabbing different parts, grats, you've been paying attention.

Any way to extract mitragynine from kratom? by Reuben Pandermedge - Tue, 13 Nov 2018 17:24:30 EST ID:pv6fN59z No.79275 Ignore Report Reply Quick Reply

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.

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.

It's a method of slowing the collapse of the housing bubble. This significantly raises the cost of constructing new homes, in a way that the scales are entirely fucked against cheaper homes. It's a means of market manipulation.

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.

>>Why isn't it used everywhere?
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.

so i was thinking of making some chloral hydrate but i would prefer to avoid fucking with chlorine gas then i had this idea basically use the same same method as for chobutanol but replacing the acetone with formaldehyde then either just use the tricholroethanol as is or oxidize it with probably dichromate and sulphuric acid to chloral. dose anyone know a reason why the reaction used to make chloral hydrate would not work with an aldehyde as well as it whould work with a ketone?
