A Silver Microscope made for a King

A beautiful microscope made in the 1700s by the master mathematical instrument maker George Adams. It is made from a combination of brass, ebony, glass, tin, steel and (most prominently) silver!

The microscope is thought to have been made for the Prince of Wales, later George IV; it was presented to the Science Museum in 1949 by George VI. A similar example held by the Museum of the History of Science, Oxford is supposed to have been made for George III

George Adams was appointed mathematical instrument maker to the Prince of Wales (later George III) around 1756 and his family firm was one of the most prominent of those at work in London during the 1700s.

dr ratio x top male reader

this idea came to me in a dream..... dr ratio it seems i've grown quite fond of you. nsfw, gets wholesome at the end

"see, dear, if you insert your cock in me at exactly 67 degrees to the right, we'll both feel the maximum amount of pleasure." dr ratio says confidently as he precisely adjusts your tip at his entrance to his desired position. "are... are you sure?" you can't help but stare incredulously as he treats your cock like it's a mathematical instrument. "don't be silly. i'm always right." lying beneath you, he finally finishes calibrating the angle he wants you to fuck him in. "okay. put it in me now!" he declares triumphantly, clearly proud of his own work. you can't help but shake your head fondly at his antics, his dedication to using his intelligence to "optimise" every situation was rather.... silly sometimes. nevertheless, you push into him slowly, enjoying the sound of him trying the stifle his moan at the feeling of your cock stretching his tight walls. "s-see. i told you so- mmph." his pride meant he'd completely deny this in front of anyone else, the way you'd fucked him like a whore, thrusting in and out of him at "the optimal speed" (according to him), but in private, you were the only one who he wanted to please. increasing your speed of your thrusts without warning, you can't help but smirk at the way he bucks his hips into you, legs shaking and hole clenching even tighter. "you idiot! i told you to follow the speed-" he starts to protest, but he's quickly quietened by your hand over his mouth as you lean forward and whisper lowly to his ear. "you talk too much, baby." he shudders at your words. "need some....stern teaching?" despite the intimacy of the situation, you have to try not to laugh as you repurpose the conversation you had a few days ago to rile him up. hearing you use his own words to tease him, he glares at you, but can't get any words out as his mind is so focused on being pummelled by your cock. it's so pathetic, he thinks to himself. usually his brain is so busy, endlessly pondering, but now he can't think of anything but the way you're fucking him. "shit...i'm gonna cum..." you breathe out as you hold his hips, almost reaching your limit. "do it in me." he says sharply, his attitude coming back in an instant. you have no choice but to oblige, pumping him full as the both of you climax. the two of you collapse onto the bed, a heap of sweaty bodies and unspoken affections. you lie on his chest as he strokes your hair, trying to catch your breath. "well done. plus 10 points." "what the fuck are you saying??" you laugh as you throw the pillow at him. "nothing... just talking to myself." "weirdo."

︵‿︵‿୨♡୧‿︵‿︵

"you know, you might be an idiot, but you're my idiot." he suddenly says, looking back as you soap his hair in your shared bath, cleaning up from your intense session earlier. his words carry a level of warmth to them despite their bluntness, a warmth he'd never give to anyone else. "stop calling me an idiot." you pout, leaning forward to smack him on the head playfully. "i'm serious! don't worry your pretty head about anything, i can do more than enough thinking for the both of us." you place your arms around him and hug him from the back in a tight embrace, the warm water surrounding you only adding to the romantic atmopshere. "whatever you say, veritas." ♡

omg i based his personality completely off his leaked voicelines and tried to incorporate some of them here hfgdhgd

LaRue Burbank, mathematician and computer, is just one of the many women who were instrumental to NASA missions.

4 Little Known Women Who Made Huge Contributions to NASA

Women have always played a significant role at NASA and its predecessor NACA, although for much of the agency’s history, they received neither the praise nor recognition that their contributions deserved. To celebrate Women’s History Month – and properly highlight some of the little-known women-led accomplishments of NASA’s early history – our archivists gathered the stories of four women whose work was critical to NASA’s success and paved the way for future generations.

LaRue Burbank: One of the Women Who Helped Land a Man on the Moon

LaRue Burbank was a trailblazing mathematician at NASA. Hired in 1954 at Langley Memorial Aeronautical Laboratory (now NASA’s Langley Research Center), she, like many other young women at NACA, the predecessor to NASA, had a bachelor's degree in mathematics. But unlike most, she also had a physics degree. For the next four years, she worked as a "human computer," conducting complex data analyses for engineers using calculators, slide rules, and other instruments. After NASA's founding, she continued this vital work for Project Mercury.

In 1962, she transferred to the newly established Manned Spacecraft Center (now NASA’s Johnson Space Center) in Houston, becoming one of the few female professionals and managers there.  Her expertise in electronics engineering led her to develop critical display systems used by flight controllers in Mission Control to monitor spacecraft during missions. Her work on the Apollo missions was vital to achieving President Kennedy's goal of landing a man on the Moon.

Eilene Galloway: How NASA became… NASA

Eilene Galloway wasn't a NASA employee, but she played a huge role in its very creation. In 1957, after the Soviet Union launched Sputnik, Senator Richard Russell Jr. called on Galloway, an expert on the Atomic Energy Act, to write a report on the U.S. response to the space race. Initially, legislators aimed to essentially re-write the Atomic Energy Act to handle the U.S. space goals. However, Galloway argued that the existing military framework wouldn't suffice – a new agency was needed to oversee both military and civilian aspects of space exploration. This included not just defense, but also meteorology, communications, and international cooperation.

Her work on the National Aeronautics and Space Act ensured NASA had the power to accomplish all these goals, without limitations from the Department of Defense or restrictions on international agreements. Galloway is even to thank for the name "National Aeronautics and Space Administration", as initially NASA was to be called “National Aeronautics and Space Agency” which was deemed to not carry enough weight and status for the wide-ranging role that NASA was to fill.

Barbara Scott: The “Star Trek Nerd” Who Led Our Understanding of the Stars

A self-described "Star Trek nerd," Barbara Scott's passion for space wasn't steered toward engineering by her guidance counselor. But that didn't stop her!  Fueled by her love of math and computer science, she landed at Goddard Spaceflight Center in 1977.  One of the first women working on flight software, Barbara's coding skills became instrumental on missions like the International Ultraviolet Explorer (IUE) and the Thermal Canister Experiment on the Space Shuttle's STS-3.  For the final decade of her impressive career, Scott managed the flight software for the iconic Hubble Space Telescope, a testament to her dedication to space exploration.

Dr. Claire Parkinson: An Early Pioneer in Climate Science Whose Work is Still Saving Lives

Dr. Claire Parkinson's love of math blossomed into a passion for climate science. Inspired by the Moon landing, and the fight for civil rights, she pursued a graduate degree in climatology.  In 1978, her talents landed her at Goddard, where she continued her research on sea ice modeling. But Parkinson's impact goes beyond theory.  She began analyzing satellite data, leading to a groundbreaking discovery: a decline in Arctic sea ice coverage between 1973 and 1987. This critical finding caught the attention of Senator Al Gore, highlighting the urgency of climate change.

Parkinson's leadership extended beyond research.  As Project Scientist for the Aqua satellite, she championed making its data freely available. This real-time information has benefitted countless projects, from wildfire management to weather forecasting, even aiding in monitoring the COVID-19 pandemic. Parkinson's dedication to understanding sea ice patterns and the impact of climate change continues to be a valuable resource for our planet.

I might b getting a cold tht is making me tired but I have a single idea I wanted to send in before I succumb

O!Steve is the God of Children & Protection, his temples r often safe havens for orphans or run aways, first time mothers pray both to O!Joyce the Goddess of Parenthood & War AND Steve the God of Children & Protection for an easy delivery & a healthy child

Steve loves walking hidden behind a glamor among mortals, especially on his festival days, he takes many forms but enjoys running with other young children as if he is one of them, his statues & mosaics & paintings depict him most often as a youthful omega with broad shoulders & eyes like stars wearing a type of clothing tht is worn by children till they come of age

It is on one of his festival days tht he meanders into the city of Hawkins from the woods as if he is a traveler come to give offerings to his own temple, he walks the streets enjoying the sounds of children laughing as they receive free treats & new toys from the priests & priestesses of every temple but especially his, one child runs into him & he stops them from apologizing by pulling out from seemingly thin air something the child had wanted but wasn't being offered among the toys, a book of mathematics. The child is gleeful & when he looks up from the book to thank the stranger (Steve) he is gone. Several more children end up getting gifts directly from Steve throughout the day, an older brother gets a slingshot while his little sister gets a sweet treat not offered at any of the stalls, a red headed girl is given a board of wood crafted w 4 wheels to replace the one she'd broken by accident (she never told this traveler abt her broken board) & her friend who's a resident of Steve's temple is gifted a necklace of finest carved wooden beads after Steve winks at her when she almost blows his cover after immediately seeing beyond his glamor. A timid boy w an unfortunate haircut is given drawing tools & materials. A snarky boy who reminds Steve of a huntress he once loved is gifted a book of various stories from around the land while his much younger sister clutches the cat doll Steve gives her tht she promptly names Cheese.

There's great fanfare as the festival reaches its main event, Steve is curious since every village/town/city does something different for this event. The city of Hawkins puts on a story contest each year tht is judged by the children's response. This year someone steps up last to tell their tale who Steve instantly recognizes as not mortal. This person's tale is decidedly dark & scary & it details some sort of future wherein the God of Children & Protection is to submit to the God of Darkness & Monsters who oversees the world of the monsters & shadows & forced to become his wife. The temple objects loudly to this tale, shouting tht Steve is a virgin God who swore off marriage & courtship & mating when a foolish mortal huntress played w his heart hundreds of years ago, to which the stranger responds he is merely telling the tale of what he wanted, a tale he will make true no matter what it'll take & when the ppl try to get the stranger to leave the stage the stranger suddenly begins to morph & change shape till he towers above the crowd with horns like a crown, claws instead of fingers & alpha fangs larger than is possible.

This is Vecna the God of Darkness & Monsters who is said to never leave his domain of shadows. He proclaims he will lay low the temple tht houses the orphans & run aways of the city & nearby villages tht he will even slaughter the children if he must till Steve appears to him & comes w him as his bride

Steve is abt to reveal himself & jump to protect the children the God is aiming to swipe his claws at when a man runs forward from the crowd brandishing a string instrument tht he uses to knock away the attempted attack, this man then also morphs & changes. The man is now crowned w a wreath upon his head tht reveals him to b a God tht had newly arrived to their land whose cult was still growing without any temples or altars, he has no name tht the humans or others in the Pantheon know, simply taking up the epitaph of the God of Indulgence & Storytelling. This new God bares his own Alpha fangs & declares he would not sit idly by while such a God of Monsters told a tale only meant to scare another into submission.

Then it is pandemonium as a clash btwn Deities begins. The ppl r evacuating the area, many adults prioritizing the children while Steve's temple is also cleared of ppl & Steve feels an anger simmering in his stomach tht boils over when he sees the boy tht he'd given the mathematics book to trip over a rock & begin calling desperately for his mother as she's swept away by the tide of panicking bodies. It explodes when he sees the boy with the slingshot carrying his sister on his back trying to help the mathematics boy up & away. Then Steve cannot contain himself as the little girl who he gave a doll is clutching it & crying as she has also clearly lost her family in the chaos & is does not know where to go.

Steve is charging forward shedding his glamor & pulling from within his clothes a long metal weapon w sharp spikes at the tip. He cuts short an attempted swipe from Vecna aimed at the stomach of the other Deity tht jumped to the children's defense. The alpha God snarls & finds himself out numbered. He continues to fight on two fronts for four days & four nights till Steve calls upon the leader of the Pantheon to intervene in Vecnas disregard for his banishment. Vecna tries to grab Steve around the wrist as he begins to retreat to his world of shadows & monsters but the new God intervenes again as the sky rumbles w the approach of Hopper the God of Justice & Storms, essentially breaking Vecnas own wrist. Then Vecna has retreated & Steve's ire is cooling as he turns to see the destruction wrought by a clash of Deities.

The mortals seem to all b safe, especially the children. The temples r untouched but other buildings have been felled. Steve turns to thank the other God for interfering when he did, but he finds this new God sunk to the ground clutching at a wound on his stomach. Steve is at his side as a grim faced Hopper descends with a furious Joyce at his side, Steve is afraid to touch in case the wound is made worse. This new God's condition begins to worsen till Murray the God of Politics & Love appears with little fanfare telling Steve to simply hold him & let this alpha God scent him.

Steve feels a deep pull within him at Murray's words & as he gathers this new God within his arms he feels a warm light blooming wherever they touch. As Steve cradles his head near his neck the scent he exudes causes a response from the other & when they pull apart to look at eachother without the threat of battle all wounds r healed. Without thought the God of Indulgence & Storytelling then tells Steve his name, Eddie.

Eddie asks to court Steve without a thought to the Deities & gathering mortals around them. Steve heartily agrees.

Hundreds of years from tht battle art depicts Steve the God of Children & Protection embracing his husband & consort Eddie the God of Indulgence & Storytelling

OH YES DELIGHTFUL🥰🥰🥰

𝐖𝐈𝐋𝐃 𝐓𝐇𝐈𝐍𝐆𝐒 𝐍𝐄𝐕𝐄𝐑 𝐋𝐀𝐒𝐓

𝐬𝐮𝐦𝐦𝐚𝐫𝐲: all his life, zoro had been dragging you away from danger. but sometimes, you just slip through his fingers.

𝐩𝐚𝐢𝐫𝐢𝐧𝐠: roronoa zoro x sister!reader

𝐰𝐨𝐫𝐝 𝐜𝐨𝐮𝐧𝐭: 6.8k

𝐜𝐨𝐧𝐭𝐞𝐧𝐭: swearing, use of Y/N, reader is zoro's sister, fluff before the angst, canon typical violence, death, can be interpreted as both anime and live action zoro, apparently all i do is angst now 🥰

𝐭𝐫𝐚𝐜𝐤𝐥𝐢𝐬𝐭: fine line, instrumental

For as long as Zoro could remember, he’d been the one looking after you. Day and night, he watched your every move, ensuring you didn’t do anything stupid. Doing stupid stuff just happened to your favorite hobby. It was taxing keeping you out of trouble, sure, but Zoro was all you had left, so despite only being a year your elder, he took it upon himself to care for you.

But he was so young, and you were so… unhelpful.

Reckless. Wild. Unthinking. A menace, that’s what you were. Zoro could barely even blink before he was dragging you away from a cliff’s watery edge by your ear. 

“But Zoro!” you whined. 

“But nothing,” he gritted.

You grew more restless by the hour, it seemed, always trying to tug him along on an adventure you swore would be worth his time. Zoro relented most days, if only to keep you alive (Because he’d never admit your adventures were actually fun).

Zoro supposed your habit of wandering off wasn’t so bad. You were the whole reason he’d found the dojo in Shimotsuki Village, after all, having wandered so far you reached another end of the island for him to chase you to. Besides, he was in no place to talk; he got lost just as easily, if not more.

Difficult didn’t do the feeling of trying to keep up with you justice, and it only grew harder the older the pair of you got. 

“Come on, Zoro!” you pleaded, gripping his hand.

“I’m busy,” he muttered, shrugging you off.

He spent his days studying the blade, and you were left to your own devices until an old tutor got her hands on you, teaching you mathematics and literature day in and day out. Every night before bed you complained and complained, whining that you’d much rather be running around the pastures or, better yet, training with Zoro.

But there was an ever-widening gap between you and your brother, even if you didn’t see it just yet. In your eyes, things were just the same as always, but your brother was headed on a very different path. 

He would go down in history, no doubt. Your tutor and most of the village agreed. And you… well, no one knew what to make of you. You were simply there most days. 

And as days came and went, Zoro paid less and less attention to you. It used to be easy to distract him into playing make believe, pretending to be pirates battling over treasure, but then he and Kuina made their vow, and Zoro threw himself further into his training.

And you, more interested in pretending than actually fighting, fell behind.

All you’d wanted to do was play with him and Kuina, but Zoro seemed adamant on being mean that day.

“We’re not playing,” he snarled back at you. “We’re training. Go play with someone else.”

You huffed and tried to stomp on his foot, missing by an inch. “Nobody here likes me! And I can train too!”

“Really?” Zoro scoffed. “You can barely even walk without tripping.”

Kuina stood off to the side, waiting for her friend to join her again, when she’d had enough of his sour tone. “Zoro, don’t be cruel.” Her sharp eyes roamed to you. “If you go find a training sword, we’ll let you come with us.”

Your whole face lit up, nodding quickly as you set off at a sprint to the dojo. Zoro groaned and turned to glare at her. “Why would you say that?”

“Because,” Kuina snapped, gripping his wrist and dragging him back down the path. “Now we have a head start.”

A few minutes later, you rushed back to where you’d left Kuina and Zoro, a training sword in hand, and briefly tripped over a raised stone. When you lifted your head, smiling brightly, they were gone, far off into the forest to train alone.

Some of the other kids from the dojo walked past, heading inside, when they spotted her. One leaned into the other, whispering just loud enough for you to hear: “Pathetic. Does she not have a life?”

Your lips curled into a frown and you threw down the sword, gritting your teeth.

Zoro apologized later, of course, eventually feeling bad when he came home to find you sulking in the corner. He promised he’d teach you how to wield a sword someday, which did wind up dragging a little smile out of you. Yet, that day never came. Weeks and months went by and Zoro drifted further and farther away. 

But you just couldn’t let him go, nagging and nagging and nagging.

“Can I train with you and Kuina today?” you asked, meeker than usual. You figured you knew the answer, but still, you had the nerve to hope. 

But then Zoro shifted awkwardly, hesitating to answer, and you just wanted to go back to your books. You’d gotten a new one recently, about the ocean and its mystery. 

“Listen,” he started. “I’ll play with you when we get back, okay?”

Your jaw set. Usually, you backed down pretty quick. You respected yourself enough to not chase after him all day. Today was different, though. Today was your birthday. “I don’t want to play. I want to train to be strong like you and Kuina.”

“Then I’ll train with you later.” 

He was gone the next moment, kicking up dust as he left you all alone. You wanted to hate him, since hating was usually so easy for you, but you couldn’t. 

Zoro was all you had left.

But he had someone else besides you, someone he much preferred to spend his time with: Kuina.

You found it was much easier to hate Kuina.

You weren’t at all subtle either. From little jabs to plain glaring, Kuina got the message. To your great disdain, she found it funny, cute even.

It was your obvious dislike of her that eventually brought her to give you the time of day, approaching you whilst you were reading.

“Good book?” came the voice of your arch nemesis. 

Glaring up at her, you pushed your reading glasses up your nose and shifted away from her, refusing to respond.

Her breathy laugh only spoiled your evening further. “I take that as a no…?”

“Leave me alone, Kuina.” 

Instead, she sat down beside you, leering over your shoulder to see what you were reading. “History? Sounds… fun.” You shifted away from her, and she followed. “Do those glasses really help?”

You snapped your book shut just as she reached to touch the page, nearly getting her finger. “I don’t know why Zoro likes you so much. You’re annoying.”

She grinned at you like you’d fallen right into her trap. “Is that why you don’t like me? ‘Cause Zoro won’t hang out with you anymore?”

As if she wasn’t infuriating enough, she was also very right. You jumped to your feet and glowered down at her. “You know what your problem is?”

She was standing in an instant, towering over you with that damn smile. “You gonna tell me, Roronoa?”

“Yeah!” You clenched your fists and grit your teeth. “You’re—You’re a brother stealer!”

“A brother stealer?” She had the nerve to laugh. “Please. We’re training to be the greatest swordsman or swordswoman in the world.”

You exasperated, “So?”

“So,” she said, “I’m not trying to steal your brother. But I can help you steal him back.”

Breathing heavily, you slowly lost your fire, confusion washing over your face. “What?”

Kuina shrugged. “I’ll train with you.”

Sputtering, “And why would I wanna train with you?”

“Because I’m the only one here who can beat Zoro.” She leveled her gaze with yours, something evil in that smirk of hers. “You wanna impress him? Train with me.”

“I…” She was serious. You’d seen the hard look in her eyes before; it’s how she looked right before she kicked somebody’s ass. You swallowed thickly. “Okay.”

That was how it started. An hour before Zoro was up, early before the sun, you and Kuina got to work. You were a tough student, with a spitfire attitude akin to your brother’s and all the clumsiness he lacked. 

When you tried to quit, Kuina advanced with her sword two times as fast, forcing you to block and parry like she knew you could. 

Months went by, and Zoro was all too unaware. You and Kuina had done a good job of keeping up pretenses, sharing secretive grins when Zoro’s back was turned. The one time he nearly found you out was when Kuina’s sword nicked your arm, and Zoro found you haphazardly trying to bandage it up. His line of questioning was rapid fire, panicked in every sense of the word as he did it for you.

Then, Kuina caught you by surprise; she said you were ready, and no amount of frantic head shaking would make her think otherwise. 

You didn’t have a real sword, you said, showing her your wooden practice weapon as if to prove it.

She’d simply given you that damn smirk and swapped the wood for her own sword. All breath left you as she closed your hand around her family sword. 

That was all the encouragement you needed, and she left you standing outside your little home to get ready for her training session with Zoro. The sun was barely peeking up over the horizon. You could barely hear the sound of Zoro rustling around inside the house behind you, and your fist tightened around the hilt of Kuina’s prized sword.

Zoro briefly wondered why you’d gotten out of bed so early when he noticed your blanket tossed aside, you nowhere in sight. You must be playing somewhere else, he decided, finally ready as he headed outside.

You were certainly not what he expected to find waiting for him. Your hands were held behind your back, your eyes ever like a does. A sigh dragged out of him as he approached you, meaning to walk right by you like he usually did.

“I’ll play with you later—”

In a blink, the shining edge of a blade was in his path. Stumbling back he followed the blade to that familiar hilt, now held by his little sister. The doe eyes were gone, replaced by a serious gaze he was unaccustomed to.

“What about now?” You retracted the sword and took a battle position, arcing the blade around before placing both hands on the hilt. 

He backed away from you, crossing his arms, not wanting his hands to be anywhere near the hilts of his blades. “I’m not fighting you.”

That only spurred you on. “You don’t have a choice.”

There was a wary look in his eyes before you surged forth to begin the duel. Kuina stood off to the side, eyes alight, and helped you dust off your clothes when Zoro inevitably knocked you to the dirt in a matter of minutes.

Your chest heaved as you leaned on Kuina, eyes dangerously narrow. You refused to look at Zoro.

“You’ve been training her?” Zoro guessed, not sounding angry or frustrated… just confused, and maybe sad.

Kuina nodded. “We’ve been working, yeah. She’s good, right?”

The compliment meant nothing. Humiliation coursed through your veins, the Wado Ichimonji burning through your skin. 

“Whatever,” you murmured, shoving Kuina’s sword back into her hands before stomping off into the woods.

Zoro watched you go, unable to ignore when Kuina bumped his shoulder and said, “She admires you. It’s about time you give her the time of day.”

So he trudged after you, wondering what the hell he was supposed to say.

Zoro wouldn’t say it out loud, but you were good. Far better than he remembered you being. Kuina was probably a better teacher. More patient, most likely.

But… he couldn’t help but wish it’d been him to train you up to be able to wear him out like you did. Zoro swallowed that thought and settled on finding you first, and having regrets later.

He found you sitting on a patch of grass, wiping at your damp face. Zoro made you cry. and he had the sense this wasn’t the first time.

Some brother he was.

So he ditched his hesitation and settled down on the grass beside you, testing the waters. You didn’t sprint off into the brush, so he took that as a good sign.

“What do you want?” you said first.

“I… You did well. Really well.” He pulled at some grass, ripping it apart. “I’m sorry I’ve been…”

“An asshole?” you supplied. “A major dick? A stick in the mud?” 

Zoro huffed a laugh. “All of the above?”

“It doesn’t matter,” you said, turning away, going serious again. “I didn’t beat you.”

“Did you expect to?” Your huffy silence was answer enough. “Y/N, I’ve been training for years.”

Your eyes found him then, all slits and sadness. “And I haven’t, yeah, I know. Why’s that, ya think?”

He ruffled slightly. “You could have joined us in the dojo.”

“Like hell I could have. I’ve said it before—those kids don’t like me. Besides, it’s your thing. You would have found some reason I should quit.” 

Did he really make you feel that way? Zoro felt it was fair, all the times he’d brushed you off coming to mind, and he grimaced. Then, he started to think. “Why do you want to learn to fight? I didn’t think that was your thing.”

You took your time to answer, tugging at your own grass and tossing it into the wind. “I hate being left behind. I thought if I could impress you, you’d… you’d play with me again.”

Hearing that made Zoro feel so much worse. The pair of you might be getting older, but at the end of the day, you just wanted to be around him. Zoro let the silence hang in space between you for a few moments, before he rolled to the side and swiped a long stick on the ground.

Your confused eyes followed him, widening when he pointed the stick at you. Zoro grinned and started to poke at you, causing you to scramble back on the grass. 

“Stand and fight, pirate!” he bellowed. 

Immediately, you jumped to your feet, an exhilarated smile popping onto your face. You dodged left and took up your own stick sword, holding it in front of your face as you circled your brother.

Who were you today? A fellow pirate? A pirate confronting a marine admiral? Perhaps you were brother and sister pirates, crossing paths after years of pursuing the other for vengeance. Whatever make believe you and Zoro were in today, you relished in it, knowing someday you’d have to accept the fate of growing up.

So for now, you fought your brother in the only way you were equals: pretending, your imagination spinning circles around his as his skill spun around yours.

Zoro had missed you, he realized. Being so caught up in being better for you, in being the one to make you proud, he forgot how fun simply existing alongside you could be. 

So he followed you deep into the woods, tripping over his own feet and grunting at your lofty laughter. You led him up hills and through brush, up trees and back down, and all around the island till Zoro couldn’t help but wonder what exactly you saw in the forest that he didn’t.

“That girl is wild,” your tutor said once. “It’s like she’s more at home in the trees.”

She said it in some kind of scornful way that mothers do, when they’re half upset and half in reluctant wonderment. He had to agree with the old woman, for if Zoro couldn’t find you, chances were he’d discover you in the forest, atop a rock or up in a tree.

Oftentimes, if it wasn’t Zoro clinging to the lower branches while you laughed at him, Kuina was with you. Neither of you had ever wanted for a sister, but neither of you were exactly complaining either. 

Zoro stood with his hands planted on his hips, head tilted back and still not exactly able to see where you and Kuina sat giggling amidst the branches of the ancient oak tree. 

“Y/N!” he shouted, hoping his voice would at least reach you. “Come down!”

“No!” you laughed back down. A few leaves trickled down, and a pang jerked Zoro’s heart around. How high up were you?

“It’s not safe!”

Kuina rolled her eyes. “Says you! We’re fine!”

He hardly believed her, his nails starting to dig into his palms. “C’mon! It’s gettin’ dark!”

You looked toward the horizon line, spotting the sun just as she dipped behind the mountains. Instantly, you were entranced, aching to join her. The wind whistled in your ears, as it often did, and you leaned forward just a bit. 

“He’s right,” Kuina huffed. “My dad will be mad if I get home after dark.” When you didn’t reply, she tried to catch your faraway gaze. “Y/N?”

Despite your hummed acknowledgment, your eyes were shut, a pleasant grin pulling at your face. Air tickled your cheeks, ruffling your hair, sending you the scent of miles away cherry blossoms.

You could have sat in that tree all night and into the next, but Kuina was tugging on your arm, dragging you out of the moment. You blinked like you were awakening from a deep slumber. “Sorry, what?”

“It’s time to go home,” said Kuina. 

“Oh. Right.”

You descended the tree without much thought, finding purchase for your feet and hands to grip as if the tree was reaching out to catch you, whereas Kuina very nearly fell to the ground more than once. Zoro awaited at the bottom of the tree, arms crossed and brows taut.

He watched as you grinned, eyes somewhere else entirely, and trotted back to the village all merry-like. Kuina plopped to the grass beside him, teetering on her feet before he caught her arm. 

“Thanks,” she sighed. “I don’t know how she does it so naturally.”

Zoro thought back to what the old tutor once told him. It’s like she’s more at home in the trees. “I dunno. It’s… cool, though.”

You were cool, he meant to say, but wouldn’t ever say it out loud. His little sister, who could catch fish with her bare hands and find four leaf clovers like they were nothing, was very much cool in his eyes.

He thought it again that night, when Kuina joined them for dinner with food her father had prepared, and you lurched forward to tuck a forget-me-not behind Kuina’s ear. 

“These don’t grow on the island,” Kuina pointed out. You simply grinned, like you had some secret nobody else could understand.

Kuina became just as important to you as she was to Zoro. Which is why her accident was such a travesty.

Out of the whole entire village, it hit Zoro the hardest. You would know his look of pure, unadulterated shock till the end of your days. Zoro was beside himself, and you were no better. With your only other friend gone, you had no one to lean on.

Zoro only thought of the blade—of his vow to Kuina—leaving you to mourn and dwell and be all alone. You tried to be bitter, you really did, even going to the lengths of hiding all his clean clothes just so he would talk to you, but you were still terrible at being angry with Zoro. (When all Zoro did was exist in his dirtier-by-the-day clothes, you didn’t know whether to be angry or just plain sorry for him. You settled on both).

You tried to confront him, talk to him, anything, but all he’d done was sigh and say, “Just… go read, or something. It’s good for you.”

Like you’d listen to a word he said… but reading was all you could do. It was how you winded up back on your tutor’s door step with a ducked chin and folded arms. She pursed her lips, setting a hand under your chin, cupping your face as she beckoned you inside. Each day you poured over texts and tomes till Shimotsuki Village was completely dry of new literature.

The old woman taught you till she died. Despite how life had fled your eyes, she called you Wild till her last day. “You can’t stay,” she said in her dying breath. “Wild things never last here.”

Like you’d ever think of leaving Zoro. 

But soon came the day when Zoro, like you, could learn no more from that village. You assumed the pair of you would set out together now that your paths led you away from home. Zoro had other plans.

Three swords rested at Zoro’s hip, one heartachingly familiar with its white hilt and glimmering blade. He was hunched over a bag, collecting supplies from your little home. 

“So that’s it?” you spoke into the tense silence. “You’re leaving?”

“I have to fulfill my promise to…” He didn’t finish, her name hanging in the air. “We always knew I’d leave one day.”

“And what about me?” you demanded, daring him to admit he was abandoning you. 

Instead, he closed his satchel and stood, back still facing you. “Sensei promised he’d look after you.”

“Even if I wasn’t already an adult,” you snarled. “I don’t want your sensei. I want my brother.”

Your eyes glistened with tears behind your readers, still sat on the bridge of your nose from where you’d been annotating the last of your tutor’s dusty books. He glanced up, catching your eye, and immediately returned his gaze to the floor. 

“I need to become the world’s greatest swordsman,” Zoro said as he walked past you, brushing shoulders with you before he stopped just at the door. “For Kuina. And I need to do it alone.”

Catching your breath, you shook your head at him. “No. All my life I’ve been so patient with you. I’ve forgotten every time you forgot me, everytime you were mean to me—I let it all go! You—You don’t get to let me go. That’s not how this works, Zoro!” 

You felt hysterical, tears streaming down your face. And all Zoro could do was stare at the ground.

“You’ll understand someday.”

Hot anger boiled beneath your skin, making you warm all over. Your cheeks burnt and your hands balled into fists. You folded your arms over your chest to keep from lashing out at him with the fury of a sister scorned. 

You would never understand. 

He breathed shakily. “I… love you, Y/N.”

It was like a bullet to your heart. You peered over your shoulder to find his back just over the threshold of the door, one hand on his three swords and the other rested on the doorframe. You hadn’t stood up to Zoro in many years, mostly because he hadn’t given you reason to. Until now.

“You really are stupid.”

“Y/N—”

“Don’t waste your breath,” you snarled, sweeping over to your desk and grabbing your ready-and-packed satchel. Wiping your nose and eyes on your sleeve, you steeled yourself and swallowed up all your cries. “Where are we headed?”

You turned, adjusting the satchel on your shoulder, and lifted your gaze to your brother, who had turned to stare at you. Faltering, you tried to gauge what Zoro was thinking, what had always been an impossible task. Zoro had never looked at you like this before, his eyes void of any hostility or pity or annoyance. For a moment, he wasn’t an apprentice or a swordsman, nor was he Kuina’s legacy.

He was Zoro, the brother who could have hung the stars with how much you believed in him. 

And for a moment, Zoro wasn’t looking at his baby sister, helpless in every sense of the word, desperate to prove herself—Zoro saw what Kuina had, once upon a time; a warrior more mind and spirit than strength, the force of a thousand soldiers behind her puffy red eyes.

It was terrifying, to say the least. You weren’t so little anymore, and he didn’t feel so big anymore. 

“First,” he grumbled. “We’re getting you a sword.”

Your eyes shined, not from tears (he was glad you still had your wonder intact). “And second?”

“We’re going after Dracule Mihawk, the greatest swordsman in the world.”

Standing at the docks a while later, preparing to depart, you nudged his shoulder to catch his fleeting attention. The silence had been tense all evening. Your grin was soft and unsure as you mumbled, “I love you too, by the way.” Zoro ruffled, nodding, and you pressed on with a smirk. “You’ve never said that to me before.”

“Sure I have,” he countered, but you shook your head.

“Nope. Never. But that’s okay.” You turned to stare at the ground, the captain of the ship taking you away starting toward the pair of you. “I’ve never said it either.”

And in the underbelly of that big merchant ship, sitting on the small cots allotted to you for the journey, you lifted your gaze to lock him in place. “Let’s make a promise.”

Zoro stilled, setting his swords beside him as he met your gaze. He wasn’t opposing the idea, so you pressed on, presenting your pinky to him. Zoro had the nerve to scoff. “Don’t laugh. This is a sacred ritual.”

Rolling his eyes, Zoro rested his arms on his knees, reaching to interlock his pinky with yours. A smile tugged at your face. “What’s our promise?”

You hummed, not having thought that far ahead, before getting excited again. “I promise to stay by your side. No matter how much of an idiot you are.”

For a while, he said nothing, staring at your hands in the space between you. He started to speak, thought better of it, before pressing on. “That’s a big promise. Sure you won’t change your mind?”

“Maybe,” you shrugged. “If I do, I’ll just break my pinky.”

He blinked, trying hard not to let his smirk through, and he laughed despite himself. “Fine. I promise I won’t abandon you. Ever. No matter how much a menace you are.”

Satisfied, you retracted your pinky, letting your eyes flutter shut. You yawned and laid on the less than comfy cot, and were out like a light in minutes. Zoro stayed awake at your side all night, hyper aware of every motion all around, threatening each thing that creeped in the dark recesses with a single glare. 

For you, this was a dream. The world was your playground, an adventure just like the ones you’d read about. On the contrary, Zoro was stressing. You had this penchant for getting into trouble, always finding danger wherever you went. 

Tiffs between you and your brother were never far away, but unlike when you were younger, these fights lacked a certain fire, almost as if neither of you cared to pick at the other anymore. That realization was odd, to say the least. It was almost like the pair of you were growing up.

Word quickly spread across the East Blue about the Pirate Hunter Zoro, so deadly they took to calling him a demon… and then there was you. People tended to ignore girls, looking over your head and not caring to lower their voices when you lurked nearby. You were Zoro’s main informant, picking up on locations and secrets before your targets had any clue they were being hunted.

And as weeks flew by, you and Zoro found a new kind of camaraderie; respect. After years, it looked like Zoro was finally respecting you as an equal. As a friend.

You had quite the temper, never backing away from a threat, mostly because you knew your big brother was behind you. You don’t like the price for those apples? The vendor isn’t willing to barter? You're cursing their mother and demanding a fair price, and just as the vendor is reaching for a knife there appears this giant of a man, arms crossed, eyes narrowed. You always get the price you want.

Zoro liked to shine and sharpen and clean his swords himself, but one day he was so tired he fell asleep while doing the first one. He woke up to all three glittering up at him. You said it was no problem, and went out of your way to get to the task before he did each time. 

Your habit of climbing trees returned, and with it a newfound love for scaling buildings as well. Zoro’s not sure how he doesn’t have a head full of gray hairs, but he feels for sure it's coming.

Still, despite your insistence on remaining a menace (he’s certain it’s on purpose), Zoro was happy you’re with him. Things nearly reached a new kind of normal; he hunted the pirates, you helped him, you both got paid. 

But he saw how restless you became, always itching for the next adrenaline hit. Somewhere inside, Zoro feared the day you’d get so restless you turned back to recklessness. Mostly, he feared he wouldn’t be there to save you in time. 

Zoro’s footsteps were ghostly, not a sound coming from him as he slinked up the gangway of the little pirate ship. His bandana was tight around his head, two of his swords brandished and at the ready. On his left, a pirate stood guard and was swiftly knocked out by a blow to his skull.

A routine operation, sure to bring in enough beri to get you and Zoro to the next island over. Maybe you’d even have enough left over for some decent food, he pondered, turning and laying eyes on the door to the lower decks. 

It should have been a routine operation, but the moment he stepped into the winding halls of that ship, the pirates were all over him, coming at him left and right. They drove him back up to the main deck, landing blows against his three swords yet never getting through his defenses. 

But if he stayed on the defense, he doubted he’d actually find an opening to get the hell outta there. Zoro swiped his swords in an arc to drive the horde of them away just long enough to make a break for the docks, but a gunshot rang true, whizzing past his head before he could take a step.

He whipped around and found the man he’d intended to murder in his sleep, and drag his body back without ever alerting the crew. The captain reloaded his pistol, a maniacal grin splitting his face. 

“Roronoa Zoro,” the man drawled, stepping down from the stern of the ship. “Your reputation precedes you.”

He blinked up at him, readjusting his hold on his swords. “Sorry, who the fuck are you?”

The smile dropped instantly. “Only the man who will end your sorry life, pirate hunter.”

Zoro scoffed. “I’d like to see you try.”

He heard it, but it was so soft he tried to convince himself he was delusional; but then it got louder, till he heard the sound of feet bounding up the gangway as his blood ran cold, and there you were, shouting his name, your sword held before you.

“Zoro,” you gasped, ignoring everything else as you gazed upon him with wild eyes. “It’s—It’s a trap.”

The captain’s laugh was like a ringing in his ear. Zoro’s stare was zeroed in on you, begging you to run away, horror flooding his senses. No. No. No.

“A little too late, kid,” the captain bellowed, slinging around his pistol and eyeing you predatorily. “Here to die with the hunter?”

Zoro’s heart dropped when you spat at the ground, shooting the captain a glare. The man growled, nodding at his awaiting crew. “Take care of her. I’ll take Roronoa.”

You had lunged before Zoro could do a thing, clashing your blade against your opponents and dodging each strike with ease. Zoro made to run to you when a sword swiped through the air and caught his arm, forcing him to face the captain of the ship.

A routine. This was meant to be a routine. You were meant to be safe at the little inn, awaiting his return with a gripy comment about having woken you up, despite knowing fully well you’d been up the whole time. 

But you were here, fighting for your life against ten or so men twice your size. You could only hold them off for so long. Zoro set his jaw and set his third sword between his teeth, taking on the slimy excuse for a captain. 

“Y/N!” He shouted, muffled around the hilt of his blade. “Get out of here!”

“No!” you shouted right before wincing as you took a wrong step and twisted your ankle, attempting to walk it off as you evaded being skewered. 

His eyes followed you, spying a pirate jumping down from the stern. Zoro sprinted away from his own fight, vaulting over you and decapitating the pirate, landing on the deck in a roll. You heaved, awestruck, and giggled despite it all.

Zoro stood, eyes dark as a demon’s, and looked right at you. It was as if the sun was held captive in your eyes, even now. A spot of blood seeped into your shirt, and he parried three men’s attacks to reach you. “You’re hurt.”

“I’m fine,” you snapped, your back to Zoro’s as you drove back another blow. “I’m sorry. I should’ve known something was up.”

“Don’t—” he kicked a guy to the side “—Don’t be. Just—”

He whirled on you as you let out a whimper, now clutching your shoulder. In a flash, Zoro severed the arm of the man who’d hurt you, letting you lean against him for a moment. Maybe four men were still standing, yet the captain had gone out of sight. The coward. 

His heart raced, the sound of it blaring in his ears and making it hard to gather his wits up off the ground. Zoro could barely breathe, but he managed to berate you still. “Stay down. I’ll handle this.”

You glared up at him, your eyes going wide a moment later. Your hands landed on his shoulders and pushed him down with all your might, and he keeled over, not expecting it. He rolled to the side and stood, taking out another pirate by his leg in the process, and whipped back around to yell at you.

But… something was wrong. You teetered precariously on your feet, and your face was all scrunched up, and why were you clutching your chest like that? Was there that much blood on your shirt before? 

Even when he saw the captain standing behind you with a bloodied sword, Zoro couldn’t believe what he was seeing. If anyone had seen what happened next, they would understand precisely why Roronoa Zoro was compared to a demon; the three remaining men and their captain were dead before you ever hit the deck.

Zoro fell to his knees, his swords clattering to the ground as he scooped up your head and held you to him. Your name fell from his trembling lips, his wide eyes pleading with yours to stay open. You were fading before his very eyes, the sun behind them setting fast. 

“Hey,” he stammered. “Hey, don’t go—you can’t. Remember? You don’t get to leave. That’s not how this works. That’s what you said.” You smiled up at him, and it all got infinitely worse. “Stop being—stop being stupid. You’re not dying. Get up.”

“It’s okay,” you whispered as black fuzz clouded your vision. “I’m… okay…”

You went limp in his arms. His tears didn’t make a sound, nor did he as he carried your body back to the inn, passing the innkeeper solemnly, and laid you down on the bed. He stood guard at your side till morning, and he went back for the body of the pirate captain, cashed in the bounty, and made preparations to go back home.

Your grave sat beside Kuina’s, on a nice ridge overlooking the village. The sunset in beautiful from up there.

The demon pirate hunter roamed the East Blue without an ounce of mercy, earning himself his title and reputation once and for all. No one ever dared to trap him again, not after they heard what happened to the last guys who tried. The whole crew died in twenty minutes, is what they said.

He barely spoke to anyone besides a bartender, becoming more specter than man. His eyes always had this dark tint to them, a haunting behind them that struck fear into the very soul of anyone who looked into them. 

And he liked it that way. He didn’t need anyone getting a closer look at him, not when everyone he ever cares about winds up—gone. He swore he’d never let anyone get close ever again. It was safer that way.

No one touched his swords. No one so much as brushed past them without getting an earful. Only he ever cleaned, shined, or sharpened his blades. He claimed no one ever did it right.

In truth, the demon pirate was getting sloppy, as much as he hated to admit it. He had a mission to complete, yet each day grew more difficult than the last. He took on bounties without much thought, fought anyone who spared him a glance. 

Reckless. He’d grown reckless.

It’s what led him to Shell Town. What led him to that restaurant. What led him to defending that little girl and her mother (he sees you in every child with just an ounce of wonder). It’s what brought him here, tied to this post under the blazing sun, starving and thirsty, and he felt deserving of it.

But he couldn’t die here. He’d let one promise be broken. The other would be fulfilled. He just had ten more days left, then he’d be on his way. Surely, Hawkeye Mihawk can’t hide forever. Then, after… he could rest. Only then. Only then.

“They say you’re a bad guy.”

Zoro frowned, lifting his eyes from the dirt, squinting through the blinding sun to make out who stood before him. Their outline came first, a boy, with something on his head. He blinked a few times and took in this kid who dared to step into this yard. 

He looked him up and down, took in the straw hat on his head, shielding the kid’s eyes from the sun. Yet, somehow… despite the shade being cast on his face, there was a bright glow in his complexion, but Zoro couldn’t decide where it was coming from (he refused to admit it was coming from his eyes).

This kid had the nerve to smile at Zoro, giving him the sense that maybe they had met before. Why else would that unrestrained, recklessly true smile make Zoro’s heart stop? 

(Zoro would only let himself think it some weeks later, when he’d long since accepted the offer of first mate, and long since the Straw Hat pirates found a ship of their own—Luffy reminded him of you, as terrifying as that was).

(Maybe he would let one, or two, or however many people were on that ship get close. Just maybe, it wouldn’t hurt to try).

“Zoro!” Luffy called, racing toward the afterdeck in search of the mossheaded swordsman. He jumped to a stop, finding Zoro sitting under the tangerine trees, slowly peeling one in his hand. “There you are! What’re you doing?”

He barely cast him a glance. “Trying to be alone.”

Luffy laughed at that, plopping himself down next to Zoro. “Me too.” He reached up a rubber hand and swiped a tangerine, only thinking how odd it was a moment later. “Hmm, Nami would normally skin us for eating her fruit.”

Zoro stilled before popping a slice into his mouth. “She said it’s fine. As long as I’m alone.”

The captain tilted his head, skeptical as he slowly chewed a piece of his tangerine. “Why?”

Luffy received no answer, not right away, not until Zoro finished his tangerine and set the peel in front of him to dispose of later. And Luffy waited, shredding his peel into lots of pieces just for the fun of it. 

“I had a sister,” Zoro finally confessed, causing Luffy to freeze up. “It’s her birthday.”

So many questions bubbled under the surface. Why hadn't he mentioned her? Why hadn’t Luffy met her? What’s her name? Does she have green hair too? But… Zoro’s solemn expression had Luffy falling silent, watching his face carefully.

No explanation came, but Luffy gathered the gist of it. Whoever this sister was, she wasn’t around anymore. “Do you… still want to be alone?”

Zoro hesitated, hands squeezing his knees tightly, his throat gone dry. “No.”

“Okay,” Luffy smiled softly, plucking his hat from his head and setting it on Zoro’s, slightly missing the mark and pushing it down over his eyes.

The swordsman huffed a laugh, peeking out from under the hat. “What’s that for?”

Luffy shrugged. “Dunno. The hat makes me feel better.”

Zoro shook his head, gazing softly upon his captain before adjusting the straw hat on his head and shifting to stare at the sea. “Thank you, Luffy. For everything.”

“No problem, Zoro. Hey, do you when dinner's ready?"

April 14, Xi'an, China, Shaanxi History Museum, Qin and Han Dynasties Branch (Part 3 – Innovations and Philosophies):

(Edit: sorry this post came out so late, I got hit by the truck named life and had to get some rest, and this post in itself took some effort to research. But anyway it's finally up, please enjoy!)

A little background first, because this naming might lead to some confusions.....when you see location adjectives like "eastern", "western", "northern", "southern" added to the front of Zhou dynasty, Han dynasty, Song dynasty, and Jin/晋 dynasty, it just means the location of the capital city has changed. For example Han dynasty had its capital at Chang'an (Xi'an today) in the beginning, but after the very brief but not officially recognized "Xin dynasty" (9 - 23 AD; not officially recognized in traditional Chinese historiography, it's usually seen as a part of Han dynasty), Luoyang became the new capital. Because Chang'an is geographically to the west of Luoyang, the Han dynasty pre-Xin is called Western Han dynasty (202 BC - 8 AD), and the Han dynasty post-Xin is called Eastern Han dynasty (25 - 220 AD). As you can see here, in these cases this sort of adjective is simply used to indicate different time periods in the same dynasty.

Model of a dragonbone water lift/龙骨水车, Eastern Han dynasty. This is mainly used to push water up to higher elevations for the purpose of irrigation:

Model of a water-powered bellows/冶铁水排, Eastern Han dynasty. Just as the name implies, as flowing water pushes the water wheel around, the parts connected to the axle will pull and push on the bellows alternately, delivering more air to the furnace for the purpose of casting iron.

The Nine Chapters on the Mathematical Art/《九章算术》, Fangcheng/方程 chapter. It’s a compilation of the work of many scholars from 10 th century BC until 2 nd century AD, and while the earliest authors are unknown, it has been edited and supplemented by known scholars during Western Han dynasty (also when the final version of this book was compiled), then commented on by scholars during Three Kingdoms period (Kingdom of Wei) and Tang dynasty. The final version contains 246 example problems and solutions that focus on practical applications, for example measuring land, surveying land, construction, trading, and distributing taxes. This focus on practicality is because it has been used as a textbook to train civil servants. Note that during Han dynasty, fangcheng means the method of solving systems of linear equations; today, fangcheng simply means equation. For anyone who wants to know a little more about this book and math in ancient China, here’s an article about it. (link goes to pdf)

Diagram of a circle in a right triangle (called “勾股容圆” in Chinese), from the book Ceyuan Haijing/《测圆海镜》 by Yuan-era mathematician Li Ye/李冶 (his name was originally Li Zhi/李治) in 1248.  Note that Pythagorean Theorem was known by the name Gougu Theorem/勾股定理 in ancient China, where gou/勾 and gu/股 mean the shorter and longer legs of the right triangle respectively, and the hypotenuse is named xian/弦 (unlike what the above linked article suggests, this naming has more to do with the ancient Chinese percussion instrument qing/磬, which is shaped similar to a right triangle).  Gougu Theorem was recorded in the ancient Chinese mathematical work Zhoubi Suanjing/《周髀算经》, and the name Gougu Theorem is still used in China today.

Diagram of the proof for Gougu Theorem in Zhoubi Suanjing. The sentence on the left translates to "gou (shorter leg) squared and gu (longer leg) squared makes up xian (hypotenuse) squared", which is basically the equation a² + b² = c². Note that the character for "squared" here (mi/幂) means "power" today.

This is a diagram of Zhang Heng’s seismoscope, called houfeng didong yi/候风地动仪 (lit. “instrument that measures the winds and the movements of the earth”).  It was invented during Eastern Han dynasty, but no artifact of houfeng didong yi has been discovered yet, this is presumably due to constant wars at the end of Eastern Han dynasty.  All models and diagrams that exist right now are what historians and seismologists think it should look like based on descriptions from Eastern Han dynasty. This diagram is based on the most popular model by Wang Zhenduo that has an inverted column at the center, but this model has been widely criticized for its ability to actually detect earthquakes. A newer model that came out in 2005 with a swinging column pendulum in the center has shown the ability to detect earthquakes, but has yet to demonstrate ability to reliably detect the direction where the waves originate, and is also inconsistent with the descriptions recorded in ancient texts. What houfeng didong yi really looks like and how it really works remains a mystery.

Xin dynasty bronze calipers, the earliest sliding caliper found as of now (not the earliest caliper btw). This diagram is the line drawing of the actual artifact (right).

Ancient Chinese "Jacquard" loom (called 提花机 or simply 花机 in Chinese, lit. "raise pattern machine"), which first appeared no later than 1st century BC. The illustration here is from the Ming-era (1368 - 1644) encyclopedia Tiangong Kaiwu/《天工开物》. Basically it's a giant loom operated by two people, the person below is the weaver, and the person sitting atop is the one who controls which warp threads should be lifted at what time (all already determined at the designing stage before any weaving begins), which creates patterns woven into the fabric. Here is a video that briefly shows how this type of loom works (start from around 1:00). For Hanfu lovers, this is how zhuanghua/妆花 fabric used to be woven, and how traditional silk fabrics like yunjin/云锦 continue to be woven. Because it is so labor intensive, real jacquard silk brocade woven this way are extremely expensive, so the vast majority of zhuanghua hanfu on the market are made from machine woven synthetic materials.

Chinese purple is a synthetic pigment with the chemical formula BaCuSi2O6. There's also a Chinese blue pigment. If anyone is interested in the chemistry of these two compounds, here's a paper on the topic. (link goes to pdf)

A list of common colors used in Qin and Han dynasties and the pigments involved. White pigment comes from chalk, lead compounds, and powdered sea shells; green pigment comes from malachite mineral; blue pigment usually comes from azurite mineral; black comes from pine soot and graphite; red comes from cinnabar; ochre comes from hematite; and yellow comes from realgar and orpiment minerals.

Also here are names of different colors and shades during Han dynasty. It's worth noting that qing/青 can mean green (ex: 青草, "green grass"), blue (ex: 青天, "blue sky"), any shade between green and blue, or even black (ex: 青丝, "black hair") in ancient Chinese depending on the context. Today 青 can mean green, blue, and everything in between.

Western Han-era bronze lamp shaped like a goose holding a fish in its beak. This lamp is interesting as the whole thing is hollow, so the smoke from the fire in the lamp (the fish shaped part) will go up into the neck of the goose, then go down into the body of the goose where there's water to catch the smoke, this way the smoke will not be released to the surrounding environment. There are also other lamps from around the same time designed like this, for example the famous gilt bronze lamp that's shaped like a kneeling person holding a lamp.

Part of a Qin-era (?) clay drainage pipe system:

A list of canals that was dug during Warring States period, Qin dynasty, and pre-Emperor Wu of Han Han dynasty (475 - 141 BC). Their purposes vary from transportation to irrigation. The name of the first canal on the list, Hong Gou/鸿沟, has already become a word in Chinese language, a metaphor for a clear separation that cannot be crossed (ex: 不可逾越的鸿沟, meaning "a gulf that cannot be crossed").

Han-era wooden boat. This boat is special in that its construction has clear inspirations from the ancient Romans, another indication of the amount of information exchange that took place along the Silk Road:

A model that shows how the Great Wall was constructed in Qin dynasty. Laborers would use bamboo to construct a scaffold (bamboo scaffolding is still used in construction today btw, though it's being gradually phased out) so people and materials (stone bricks and dirt) can get up onto the wall. Then the dirt in the middle of the wall would be compressed into rammed earth, called hangtu/夯土. A layer of stone bricks may be added to the outside of the hangtu wall to protect it from the elements. This was also the method of construction for many city walls in ancient China.

A list of the schools of thought that existed during Warring States period, their most influential figures, their scholars, and their most famous works. These include Confucianism (called Ru Jia/儒家 in Chinese; usually the suffix "家" at the end denotes a school of thought, not a religion; the suffix "教" is that one that denotes a religion), Daoism/道家, Legalism (Fa Jia/法家), Mohism/墨家, etc.

The "Five Classics" (五经) in the "Four Books and Five Classics" (四书五经) associated with the Confucian tradition, they are Shijing/《诗经》 (Classic of Poetry), Yijing/《易经》 (also known as I Ching), Shangshu/《尚书》 (Classic of History), Liji/《礼记》 (Book of Rites), and Chunqiu/《春秋》 (Spring and Autumn Annals). The "Four Books" (四书) are Daxue/《大学》 (Great Learning), Zhongyong/《中庸》 (Doctrine of the Mean), Lunyu/《论语》 (Analects), and Mengzi/《孟子》 (known as Mencius).

And finally the souvenir shop! Here's a Chinese chess (xiangqi/象棋) set where the pieces are fashioned like Western chess, in that they actually look like the things they are supposed to represent, compared to traditional Chinese chess pieces where each one is just a round wooden piece with the Chinese character for the piece on top:

A blind box set of small figurines that are supposed to mimic Shang and Zhou era animal-shaped bronze vessels. Fun fact, in Shang dynasty people revered owls, and there was a female general named Fu Hao/妇好 who was buried with an owl-shaped bronze vessel, so that's why this set has three different owls (top left, top right, and middle). I got one of these owls (I love birds so yay!)

And that concludes the museums I visited while in Xi'an!

Stanford Pines was in the mindscape, a void of space containing distant stars and galaxies. Floating journals, books and scrolls filled the immediate area, along with other items familiar to Ford. This place existed in his head, after all.

Ford would have been all alone here, if it hadn't been for the company of his muse, Bill Cipher.

The two were working on equations and mathematical formulas together, pertaining to the portal that Ford was currently building, under Bill’s direction. The portal was nearing completion, and would soon be ready for testing.

Bill carefully observed the calculations projected in the space, searching for any errors or possible areas of improvement. Ford, standing near the dream demon, was scribbling furiously on a piece of parchment with an old-fashioned feather quill.

“Everything looks fine to me, Sixer. Are you sure you need to alter the blueprints?” Bill inquired, still scanning over their handiwork.

Ford continued to scrawl away, determined to improve the device.

“I think there’s a way to make the gateway more stable. I just have to figure out the right equation.”

“Whatever gets you there, Fordsy.” Bill commented, his eye still trained on the projections.

A moment of silence passed between the two, before being broken by Ford, who finally came up with a solid equation.

“Aha!” He cried out. “I think I’ve done it! Bill, take a look at-”

As Ford began to move toward Bill, eager to show off his work, a journal happened to float directly in the path of his legs. As Ford stepped forwards, he tripped on the object, losing his balance and lurching forwards.

Bill turned just in time to see Ford fall. As Ford did so, however, his arms flailed outwards, the one holding the quill being extended towards Bill. The feather made contact, swiftly brushing down the length of Bill’s side as Ford went down.

As the soft object glided across Bill, he felt an internal ‘shock’ of sorts run through the area of contact. Seemingly automatically, he jerked back, a small chuckle escaping.

“Hah!”

“Bill! Are you alright?” Ford asked, pushing up his glasses as he reorientated himself.

Bill, confused about what had just happened, shook the event from his mind momentarily to address Ford.

“‘Course I am! You can’t get hurt in the mindscape, remember?”

Ford was still concerned.

“I know,” He began, “but you seemed to recoil when the quill…”

Ford trailed off, eyeing the feathery instrument in his hand. He looked back at Bill, who was floating indifferently.

No, it can’t be…

“Bill, are you… ticklish?” Ford questioned.

Bill squinted, unfamiliar with the term.

“T… tick…?”

“Ticklish. You know… knismesis and gargalesis?”

Bill stared blankly.

“It’s this thing where if someone makes contact with you in a certain way, it makes you laugh, and your body sort of… spasms.” Ford explained.

Bill chuckled in response. “Humans sure do have the most useless reflexes! It's hilarious!”

“That’s why I’m wondering how you experienced it.” Ford stated. “Could it be an effect of my dream on the mindscape? Or something else?”

As Ford pondered, Bill leaned back, crossing his legs and placing his hands behind his top point as he bobbed up and down in the air.

“Bill, would you mind if I tested a few things? Just to collect some data. I promise it won’t take that long.”

Bill stopped. He was hesitant to relive the event that had just occurred moments prior, but this was probably the closest he’d ever gotten to having someone fully construct his portal. Getting on Ford’s bad side at this stage in the game would result in a lot of wasted progress. Besides, Bill found pain to be hilarious! This couldn’t be all that different.

“Sure thing! Knock yourself out, Sixer. Just as long as you get back to work on the portal right after.”

“Great!” Ford exclaimed, beaming. He let go of the parchment, which floated off into the distance.

Bill’s ankle was suddenly seized, with Ford then pulling the triangle closer to his body. Bill dangled upside-down as Ford secured his grasp around the ankle.

Still clutching the quill, Ford positioned the feather-end so that it was hovering just above Bill’s foot.

“Test one, commencing… now.” Ford made contact, gently swirling the feather in circles over the small, black surface.

There it was again! Bill, almost instinctively, started kicking his free leg as the same sensation from before now radiated over his foot. Light giggles bubbled up.

“I see that you’re struggling.” Ford noted. “Does that mean you’re feeling something?”

“Nohot on puhurpose.” Bill giggled. “Ihit’s the sahame feelihing from befohore, but lehess intehense.”

“Are you giggling voluntarily?” Ford asked, continuing to swirl the feather.

“Noho I’m nohot! Thihis isn’t vehery fuhunny!” Bill lightly pulled at his ankle, but Ford’s grip was firm. His other leg continued to kick freely.

Ford couldn’t help but smirk to himself.

Maybe not to you.

“Alright, let’s try somewhere else.”

Ford pulled back the feather, giving Bill time to calm down. He then moved it to Bill’s side, against which he began to glide the feather up and down at a steady pace.

Bill’s eye widened as he got a brief glimpse of the intensity of the feeling at his side, this time being deliberately produced. He quickly grabbed onto the feather with his hands, moving it out and away from his body.

Ford chucked.

“Bihill, I’m trying to run an experiment here. I can’t complete it and get back to work on the portal if you’re going to resist.”

Bill could sense a slight hint of tease in Ford’s tone. He imagined all of the monstrosities that he could unleash onto Ford for putting him through this. However, he didn’t want to do anything that could jeopardize the portal’s production. Narrowing his eye at Ford, Bill slowly released the feather.

Once free, Ford returned the object to Bill’s side, continuing the same motion as before.

Bill burst out laughing.

“Hah ha hah! Ahahaha! Whyhy ihis thihis eheven a thihing?” He questioned, drawing his three free limbs in towards himself.

“Well, the most popular theory is that it was developed as a means of learning self-defense. Hence, why more vulnerable areas of the body tend to be more sensitive.” Ford explained, keeping up his motions with the feather.

“Yohou’re, ha, enjohoying yohourself, hah ha, too muhuch, Sihixer!” Bill managed to comment through his laughter.

Ford chuckled.

“Bill, tell me, which is worse? Here~…” Ford slowly dragged the feather down Bill’s side, “or here~?” Ford used his sixth (pinky) finger to lift up Bill’s elbow, effectively raising his arm and allowing the feather access to his underarm. Ford swiftly moved the feather into the area, swiping it repeatedly against the surface.

Bill’s laughter became more frantic.

“HaH! AhAHah! TheHEre! ThAHats muhUHUch woHOrse!”

“Good to know.” Ford said, grinning. He pulled back the quill, tossing it aside to float off into the distance, and dug into Bill’s side and underarm with his six-fingered hand.

Bill was overcome with hysterics, as he quickly learned that fingers tickle a lot more than feathers do.

“AHAHAHA! SIHIHIXEHER! HAHAHA!”

Bill noted through his haze that Ford showed no signs of stopping anytime soon, and at this point was clearly just having fun torturing the dream demon. Bill recognized that he wouldn’t be able to endure it for much longer.

“ENOHOHOUGH!” Bill yelled out, his yellow surface turning red and the colours of his limbs, hat and eye inverting.

Ford, taking Bill’s outburst as a sign that he was reaching his limit, removed his hand and released Bill’s ankle.

Bill spun himself upside-right, moving backwards and out of arm's reach from Ford. He hovered for a moment, recovering, before his colours faded back to normal.

Ford smiled weakly at Bill as he spoke.

“Bill, I’d like to test just one more-”

“No.”

“I promise it’s just one last small thing.”

“I’m warning you, Sixer. You better watch it.”

“I’ll get straight to work on the portal right after! You can hold me to that.”

Bill narrowed his eye at Ford, who flashed an innocent look in return.

“Fine.” Bill conceded, crossing his arms.

He floated closer to Ford, who grabbed hold of him before propping him up on one arm. With the other, Ford directed his hand to the brick in Bill’s pattern directly below his bowtie. He then wiggled his six fingers up against the area, being careful to support Bill with his other arm.

Bill curled in towards himself as the action elicited a steady stream of giggles from the triangle. He uncrossed his arms, lightly grabbing onto Ford’s sleeve as his legs fluttered.

Ford continued for a minute or two before slowing his hand to a stop. Bill remained on his arm for a moment, in a fuzzy daze, before shaking his mind clear and floating up and off to the side.

Bill adjusted his bowtie before speaking.

“Did you get your data, Sixer?” Staring Ford in the face, his expression and tone were dripping with sarcasm.

Ford averted his eyes, smiling sheepishly.

“Uh, yeah, yeah I did. Thanks for participating. Though I may have gotten a bit carried away…” He mumbled his last sentence.

Ford glanced around before becoming visibly concerned.

“No! My equation! The paper must have floated away! I’ll never find it now.”

“Hey, I’ve got a question.”

Ford looked over at Bill, who completely disregarded his statement and was now slowly floating in his direction.

“Do you experience the spasm reflex, Fordsy?”

Ford’s eyes widened. He began moving backwards.

“You know what, it’s been great here Bill, but I think that I should head back to my reality and finish up the portal.”

Bill stopped moving.

“Attaboy, Sixer. Attaboy.”

Ford then woke up with a start. He placed his hand on his head and gave a sigh of relief.

That was a close one.
