look, I know I've talked about this essay (?) before but like,

If you ever needed a good demonstration of the quote "Any sufficiently advanced technology is indistinguishable from magic", have I got an exercise for you.

Somebody made a small article explaining the basics of atomic theory but it's written in Anglish. Anglish is basically a made-up version of English where they remove any elements (words, prefixes, etc) that were originally borrowed from romance languages like french and latin, as well as greek and other foreign loanwords, keeping only those of germanic origin.

What happens is an english which is for the most part intelligible, but since a lot everyday english, and especially the scientific vocabulary, has has heavy latin and greek influence, they have to make up new words from the existing germanic-english vocabulary. For me it kind of reads super viking-ey.

Anyway when you read this article on atomic theory, in Anglish called Uncleftish Beholding, you get this text which kind of reads like a fantasy novel. Like in my mind it feels like it recontextualizes advanced scientific concepts to explain it to a viking audience from ancient times.

Even though you're familiar with the scientific ideas, because it bypasses the normal language we use for these concepts, you get a chance to examine these ideas as if you were a visitor from another civilization - and guess what, it does feel like it's about magic. It has a mythical quality to it, like it feels like a book about magic written during viking times. For me this has the same vibe as reading deep magic lore from a Robert Jordan book.

Yeah I was right and there was no way I was getting the rest of this done without making you all wait another month or two, so I just went to the next good break point. We're officially past the halfway point with Astarion though, so not too much longer before you actually get to see Rolan again!

Part 1 • Previous Part • Next Part

Full page format under the cut:

#baldur's gate 3 #bg3 #bg3 comic #I just really love Ember and Astarion's dynamic as well ok #He's who she canonly ends up with but the Rolan timeline is if Astarion had decided he wasn't ready for a physical relationship after all #in which case his relationship with Ember doesn't really change they just end up platonic life partners instead of romantic ones #that duo who everyone assumes are a couple because they might as well be but nah #hopefully gonna get to show off how Ember and Rolan work together once I get back to him cause I love their chemistry just as much #rolan x tav #tav x rolan #rolan x ember #bg3 astarion #astarion #my tav #sharky's tav #tav: ember #oc: ember #sharky art

The Chemical Structure of Redstone

So I was curious about what the chemical structure of Redstone looks like, and Minecraft Education Edition, albeit unintentionally, gives us a canon look into what Redstone is made of:

In Minecraft Education Edition, putting a Redstone Block into a Material Reducer shows that it's composed of 31 Carbon, 31 Uranium, and 38 Unobtanium, which we can assume to be measured in grams

Dividing the Redstone Block into Redstone Dust, each Redstone Dust is then composed of approximately 3.4 Carbon, 3.4 Uranium, and 4.2 Unobtanium

Again assuming that's measured in grams, that's 0.17 cm³ of Uranium, 1.496 cm³ of Carbon, and ???³ of Unobtanium per Redstone Dust

So what does this tell us about the chemical structure of Redstone? Basing this on Redstone Dust's composition, we can estimate that each Redstone molecule is composed of 3 Carbon atoms, 3 Uranium atoms, 4 Unobtanium atoms, a little under half of the time it binds to an extra Uranium and/or Carbon, and 20% of the time it binds to an extra Unobtanium

This also has some horrifying implications for how Redstone works:

Redstone would be extremely volatile as the radioactive decay from Unobtanium and Uranium would occasionally release Helium ions through alpha radiation, sometimes breaking apart Carbon into two Beryllium atoms (as it absorbs the extra proton and neutron from the Uranium) or merging into Oxygen

So Redstone should, in theory, be extremely flammable and potentially explosive, which implies that cave static, or the player mining Redstone with an Iron Pickaxe, could lead to a spark that causes an explosive cave-in

As Unobtanium is just a placeholder for unobtainable elements (hence the name), I'm going to estimate Unobtanium in this case as Unbinilium, the placeholder name for element 120

Why?

I'm estimating the Unobtanium as Redstone as being larger than the largest man-made element, Oganesson, which holds an impressive 118 protons

Each valence electron shell, from innermost to outermost, can bind with 2, 8, 18, 32, 32, 18, and 8 shells respectively, so I'd like Unobtanium to be an element we haven't discovered yet, and consequently I'd like to jump up to the next shell

While I could estimate with element 119's placeholder, Ununennium, it would have one electron in the next shell, so Unbinilium allows for easier chemical binding

So what does this molecule look like then? Well, horrifyingly...

It looks like this. As Redstone forms in crystal lattices, and only two Carbon atoms are free to bind, I can absolutely see why it's so brittle that it breaks into powder.

This makes the structure of Redstone:

C3U3Uno4 (55% of molecules) C4U3Uno4 (13% of molecules) C3U4Uno4 (13% of molecules) C4U4Uno4 (7% of molecules) C3U3Uno5 (5% of molecules) C4U3Uno5 (3% of molecules) C3U4Uno5 (3% of molecules) C4U4Uno5 (1% of molecules)

An extremely radioactive, flammable, and explosive compound.

OKAY THIS ARTICLE IS SO COOL

I'm going to try to explain this in a comprehensible way, because honestly it's wild to wrap your head around even for me, who has a degree in chemistry. But bear with me.

Okay, so. Solids, right? They are rigid enough to hold their shape, but aside from that they are quite variable. Some solids are hard, others are soft, some are brittle or rubbery or malleable. So what determines these qualities? And what creates the rigid structure that makes a solid a solid? Most people would tell you that it depends on the atoms that make up the solid, and the bonds between those atoms. Rubber is flexible because of the polymers it's made of, steel is strong because of the metallic bonds between its atoms. And this applies to all solids. Or so everybody thought.

A paper published in the journal Nature has discovered that biological materials such as wood, fungi, cotton, hair, and anything else that can respond to the humidity in the environment may be composed of a new class of matter dubbed "hydration solids". That's because the rigidity and solidness of the materials doesn't actually come from the atoms and bonds, but from the water molecules hanging out in between.

So basically, try to imagine a hydration solid as a bunch of balloons taped together to form a giant cube, with the actual balloon part representing the atoms and bonds of the material, and the air filling the balloons as the water in the pores of the solid. What makes this "solid" cube shaped? It's not because of the rubber at all, but the air inside. If you took out all the air from inside the balloons, the structure wouldn't be able to hold its shape.

Ozger Sahin, one of the paper's authors, said

"When we take a walk in the woods, we think of the trees and plants around us as typical solids. This research shows that we should really think of those trees and plants as towers of water holding sugars and proteins in place. It's really water's world."

And the great thing about this discovery (and one of the reasons to support its validity) is that thinking about hydration solids this way makes the math so so so much easier. Before this, if you wanted to calculate how water interacts with organic matter, you would need advanced computer simulations. Now, there are simple equations that you can do in your head. Being able to calculate a material's properties using basic physics principles is a really big deal, because so far we have only been able to do that with gasses (PV=nRT anyone?). Expanding that to a group that encompasses 50-90% of the biological world around us is huge.

The whole “scientists use big words on purpose to be exclusive” is such a bunch of anti-intellectual bullshit. Specific and concise language exists for a reason; you need the right words to convey the right meaning, and explaining stuff right is a hugely important part of science. Cultures that live around loads of snow have loads of words to describe different types of snow; cultures that live in deserts have loads of words to describe different types of sand. Complex language is needed for complex meaning.

The Victor Ninov situation is one of my favourite cases of scientific fraud because it's rare to see so straightforward an example of someone being brought low by their own hubris.

Like, okay, faking the synthesis of a previously unobserved element: it's one of the few varieties of scientific fraud that actually has a clear gameplan for getting away with it. The physical properties of unobserved elements are, in principle, predictable, and there are only so many ways to go about synthesising them. If you do your homework, it's not outside the realm of possibility that your claimed results will end up being at least mostly consistent with the results of subsequent legitimate efforts to synthesise that element, and any minor discrepancies will end up being dismissed as statistical anomalies and/or the product of sloppy experimental design. It's by no means an easy game to play, but it's a game you can conceivably win.

And Victor Ninov did it. He rolled the dice and he won – twice. His fabricated results for elements 110 and 112 were corroborated by later work, and nobody noticed that his actual data was a crock of shit. He got away with it as cleanly as he could have hoped. It was only the third time he tried it, with element 118, that he biffed it and claimed results which nobody could replicate, and this is the only reason his earlier frauds were discovered. If he'd quit while he was ahead, it's likely the first two incidents never would have come to light.

Like, they say the third time's the charm, and buddy here learned the hard way that sometimes, the opposite also holds true.

i find it so unfair that i cant do all the science. like what do you MEAN I can't study bio and chem and biochem and atrophysics and physics and geology and climate science. what do you MEAN i have a limited lifespan and need to get out of school at some point to get a job. i want to collect the science fields like pokemon, this isn't fair
