in all seriousness it's very alienating knowing theres Something Wrong With You. like seeing your mental illness come through in your behaviour and thought processes and knowing it's irrational and unhealthy, knowing other people are reading you as weird or stupid, and not being able to do anything about it is such a lonely experience

Random thought of the day:
My fic is not done. Nor is it abandoned. It is rattling around in my brain like a velociraptor testing the fences for weakness.

a little introduction to my newest oc for stripes ...
MEET REBECCA "STONEFACE" MCGEE!
a stubborn, stoic electrician that works on the C-130. known to be meticulous and well, stonefaced, beckie is a hard worker who claims to not have time for everything else. going by she / they pronouns, only a few people, mainly friends, actually refer to her as both, but she doesn't care to be bothered to correct anyone about it. and she certainly isn't bothered with making friends with anyone in other branches of the military. at least, not as of now.
(TW FOR MENTIONS OF DEATH AND ABUSE [PHYSICAL AND VERBAL] !!)
with her mother in the airforce, they were the only girl in the household. the only daughter. with three other brothers, she has to work extra hard to get her father's approval. which means her father them through excruciating work. beckie would wait for the day her mother came home. but she didn't, because she died on the very plane that she flew. which meant beckie had to deal with the abuse on her own, because her brothers were obviously her father's favorites. from glass cuts, to screaming and shouting, he's pretty much said it all. but she would escape by reading manuals. how to build things, how to wire them. this determination and drive got her to the force, but her smile and emotions were sucked out of her.
FUN FACTS !
beckie learned everything from her mother. it was the only thing they had to bond over.
when they first met russell, she thought he was a dork, and she couldn't take him seriously worth shit.
knows how to pilot a plane better than drive a car.
gets carsick, but is fine in the air
she's from the south. has a harsh southern accent.
has an extreme sweet tooth. russell tries to win her over with chocolate. it doesn't work. (yet)
actually really, REALLY awkward. you can't tell, but she will stand there like 🧍🏻♀️
would rather read and drink wine rather than go out.
she likes crossword puzzles !!
really caring deep down, but afraid to open up because of her childhood.
" shut up, man! one wrong move ... one wrong thing and this plane will be a bomb! "

Holy shit, they got Voyager 1 working again!
15 billion miles away and NASA was able to tweak code packages on one of the onboard computers and it worked and Voyager 1 is sending signals back to earth for the first time since November.
Incredible!

Nother reblog. I can and WILL scream about magnets for an hour or more if you let me. I love them so much.
-microphone feedback noises-
So, it has come to my attention that a not insignificant number of people are not aware that railguns aren't some spacefuture scifi weapon.
They're very, very real, and not exactly new by the standard of modern weaponry.
So, I shall infondump in honor of the 104th birthday of the railgun.
I've seen all manner of rail- and coilguns in fiction from Battletech (1986) to The Expanse (2015-2022) and various media in between. So it's not unreasonable that people should think they're some theoretical scifi weapon.
But they most definitely exist, and they're just about as awesome and terrible as they are in scifi, albeit often on a much smaller scale. The first railgun was built in 1917 by André Louis Octave Fauchon-Villeplée of France (yes I copy-pasted that, not gonna lie) and patented the following year. Coilguns predate railguns by another seventy-ish years, although the first functional coilgun was created in 1904 by Kristian Birkeland of Norway, with development starting as early as 1845. So yeah, they've been around for a good long while, if mostly as a sort of novelty.
First off: while railguns and coilguns are both a form of electromagnetic mass driver, the similarities pretty much stop there. A coilgun, often colloquially called Gauss gun (or Gauss rifle, which is a misnomer since the barrel is smooth-bore, not rifled to make the slug spin in flight) in honor of Carl Frederich Gauss, uses a series of coils around a smooth bore barrel that, when energized in sequence, pull the projectile along:
A superconducting variant of the coilgun is possible, and is called a quench gun. As far as I could find, nobody has made a quench gun yet, probably because of the stupid-low temps required for superconducting.
A railgun differs from a coilgun in that it uses two parallel rails - one positive and one negative - energized by a power supply that forms the breech, with the slug (or often the sabot containing the slug) completing the circuit between the magnetized rails:
Railguns and coilguns are both being investigated for military use, though the railgun is being pursued more in the traditional Naval artillery sense, whereas coilgun research seems to be more geared toward mortars, mass drivers for launching products into space, or other material transport systems.
Currently, the US Navy has a railgun in R&D, where's it's been for a few decades, at least.
youtube
The main issue that both rail- and coilguns run into is the absolutely STUPENDOUS amount of power they consume, with the Navy's railgun consuming nine megajoules (aka A Shitload Of Electricity). Railguns have the added difficulty of...well...breaking themselves. They generate so much force that the rails are pushed apart by the magnetic fields, and after a few shots the rails and projectile are no longer in full contact and thus begin to arc, which rapidly corrodes the rails. There's also the problem of heat generated by friction alone damaging the rails each time the gun is fired. So at present, railguns aren't viable as a weapon of war due to the lack of materials that are both electrically conductive and able to withstand the heat and force applied during firing.
There was also a brief period where, thanks to some Bad Maths, it was thought that a railgun could made to be entirely recoiless, but subsequent testing has proven that the magnetic and acceleration forces act on the breech of the railgun in much the same way that gunpowder or other propellants act on the breech of a chemical firearm.
Regardless, the technology is still awe-inspiring (at least for me; electromagnetics makes brain go brrrrrrr) and a few hundred years from now it's very possible that we'll have actual MAC cannons on warships or even tanks. We just have a lot of work to do yet.
Bonus - Here's a couple more really awesome railgun vids for yall:

Reblogging here bc well. It's relevant to the Science Twink
-cracks knuckle- Okay. Before I get into this, please read the tags.
That being said.
Tobias Buckell, I have a huge fossilized bone to pick with you.
In the book Envoy, it's mentioned that a HAVOK thermonuclear device has been repurposed by colonists to power their settlement, and is then repurposed again to power an EMP. I haven't read the book, and the synopsis on the Wiki was sparse, so apologies if I got the details wrong; it won't affect what I'm gonna say.
Things to know: Fission is the splitting of atoms by a neutron. Fusion is when atoms combine. Both release a lot of energy, but fusion is by and far away the more powerful of the two.
Firstly, nuclear weapons emit an emp without being repurposed. It's just what they do.
Secondly, while the fuel of a nuclear device can be used to power a reactor, you CANNOT just crack open a nuke, however carefully, and plonk the uranium or plutonium (or both, depending on the device) into a reactor. It is SO much more complicated than that.
Firstly: Reactor fuel, while enriched, is nowhere NEAR as enriched as weapon fuel. Also, enrichment refers to the concentration if a specific isotope of U or Pu, not how elementally pure it is. ²³⁵U and ²³⁹Pu are the isotopes found in weapons grade fuel, with the uranium being 93% ²³⁵U. Reactor grade fuels are composed mostly of ²³⁸U (about 80%, with approx. 20% being ²³⁵U) and Pu of a variety of mixed isotopes.
And like...I don't think most people know just how ungodly goddamn terrifyingly dangerous weapons-grade fuel is. These metals are ACTIVELY TRYING TO KILL YOU by this point. Plutonium can fucking spontaneously fission or, yknow, just. Catch fire. For no reason. Once a mass of Pu or U gets to a certain point, neutrons can't escape and the fission becomes self sustaining. This is the tipping point, or Critical Mass.
Even the SHAPE of the fuel matters A LOT. Yes, there are Bad Shapes when dealing with weapons-grade fuel, ESPECIALLY Pu. Bar? Billet? Ring? Yes, good. You can have a critical mass in these shapes and not kill yourself. Sphere? Better be a fucking small one. And even then, if you so much as drop something on a softball-sized sphere of Pu, you will die. 3 scientists found this out the hard way while conducting experiments on the infamous Demon Core.
Shit, even Pu IN SOLUTION can and HAS killed simply because some poor sod turned on a mixing kettle, and the vortex created pushed enough Pu solution close enough together that Cecil Kelly died a very, very bad death after only thirty-four hours. By contrast, the victims of the Demon Core lasted days and weeks, and people present at Chernobyl lasted weeks, even YEARS after exposure. These events are called criticalities, or, in a reactor, a power excursion.
On to mechanisms. Weapons first.
A thermonuclear device actually uses two phases, both fission, to set off the fusion reaction.
The implosion type fission explosive puts pressure on another fission device that contains the fusion fuel. Boom. Micro-star.
For reactors, the fuel is compressed into pellets, and then loaded into tubes called fuel rods. These rods are then loaded into a reactor core, where they generate heat that boils water and the steam turns turbines.
As Chernobyl (and SL-1) show, a reactor is capable of a devastating explosion. However, by weapon standards, the explosion is considered a 'fizzle'. This is because of the low enrichment of the fuel pellets compared to weapon fuel. Also, the mechanism of explosion is different in a reactor, depending on the type (Light Water, Pressurized Water, and Liquid Metal reactors). PWR reactors, the most common type, the aformentioned explosions, while differing in some details (core size, condition of the core, and core status at the time of the excursion) were both caused by some, or multiple, jackasses removing control rods from the core. This meant that (and I'm summarizing in the case of the Chernobyl RBMK reactor) the fission became self-sustaining, which flash boiled water, which then caused a steam explosion. (Fun fact: the SL-1 reactor experienced an excursion that peaked at TEN MI L L I O N PERCENT above what the reactor was designed to produce. The wiki article is WILD.)
All down to operator error.
Now, LMFR reactors (Liquid Metal Fast Reactors) use molten metals as the coolant. They have higher power density, are very compact, and actually in use aboard nuclear subs and aircraft carriers. They use the same fuel as a BWR.
Next: Megatons To Megawatts and Breeder Reactors (I see you kinky bastards, you sit the fuck down.)
So, theoretically, yes, weapons fuel can be turned into reactor fuel. If you know what the fuck you're doing and have all the correct, highly specialized equipment. Weapons-grade fuel has to be downblended, or mixed with natural uranium to the 20/80 ratio of ²³⁵U/²³⁸U. And reactor fuel can be used in weapons. This is where breeder reactors come in (SIT. DOWN.) A breeder reactor makes more fuel than it consumes by reacting Uranium into reactor-grade Pu, which is a mixture of isotopes. This can be used in weapons, but the yield is. Paltry, with a high chance of a fizzle.
So. Unless these fucking colonists were a bunch of nuclear goddamn physicists and nuclear engineers who just HAPPENED to have the parts for a LMFR just lying the fuck around, AND the equipment, materials and know-how to downblend AND THE RE-FUCKING ENRICH the original weapon fuel (Both of which, by the way, can take FUCKING MONTHS) there is no way in all seven goddamn circles of H E L L that a HAVOK could be used to power a city.
Tobias Buckell, I am going to put so much pudding in your underwear.
So many legos on your floor.
I am going to haunt the living AND dead shit out of you.
...
The kinky bastards may now stand.
#this is 90% comedic drama#and 10% actual complaint#so like...take this with a grain of salt#its meant to be funny yall#nuclear physics rant#sci fi#sl-1#chernobyl#demon core#cecil kelley criticality

I had to find a Louis/Janine image more *uncomfortable ahem* tamed for the second one. Just image searching for Louis and Janine almost made me want to back out asap. But I just had to get meme-crazy for these two (Yes, of course, I mean Egon and Janine).

AAAAAA OOOAAAEEEEIIIIOIUUGGGHB MEHS I LOVE THISSSSSS
Can. Can I get 2 for Egon and Victoria. 👉👈 If not that's cool I can choose someone else.
there’s technically two beds available, but it’s freezing cold and everybody knows body heat works best
Look, logically it made sense. They were in upstate New York, there were two beds, and he was SURE that they would be fine. However, with Victoria sitting there, looking at the two beds and the nonfunctional radiator, it was hard to argue the facts.
"Seriously?" He asked, running a hand nervously through his wet curly hair, "We could uh, uh, run the shower and let it heat up the entire room."
"Right," She said hesitantly, then paused and closed her eyes, "You're right. We have a plan we should stick with it."
"And, and, I snore."
"I hog the blankets. Not. Ideal in our situation." She tutted as she gathered the blankets around her.
There was an awkward silence between the two of them as Egon sat across from Victoria. She didn't really meet his eyes, but at the same time, didn't not meet them. There was a coy glance every once and a while- almost.
Nah.
Not. Inviting.
He made a show of trying to get comfortable, pulling up his too-thin blankets and even putting on dirty socks. She contributed to the madness of tossing and turning, occasionally letting out a shiver. Finally, she was the one that broke the tension.
"Egon, I'm cold. It sucks. Now, come over here. We can be adults for one night."
He rolled over, trying not to seem too glad about the prospect of throwing off his blanket.
"Statistically, the chances of us getting sick would be high." He reasoned with himself, even as she grabbed his arm and pulled him into the bed.
"Sure, whatever you need to tell yourself."
"Vic."
"Egon," she took a beat, "Also, now you want to test out nicknames?"
"Sorry."
"Apologize to me with your warmth."
He closed his eyes as he wrapped himself in her warmth and enjoyed the feeling of her warm back against his. He would never admit it to her, but it was the best damn night's rest he had had in a long time.
#SCREAMING#you captured them so well holy shit#-incoherent noises-#im so glad i saved this work was trash i needed to read something cute#ty so so so much
