Ernst Chladni

Klangfiguren, 1787

One of Chladni’s best-known achievements was inventing a technique to show the various modes of vibration of a rigid surface. First published in 1787 in his book Entdeckungen über die Theorie des Klanges, the technique consists of drawing a bow over a (circular, square, or rectangular) plate or membrane whose surface is lightly covered with sand. When stroked, a given plate will resonate at one of its natural frequencies. The sand bounces about on the plate until settling at nodal points (areas of zero movement) thereby producing intricate patterns. These patterns are now called Chladni figures.

Die Akustic, 1802

Nodal lines of vibrating circular or polygonal  plates, acording to Chladni and Savart. The breakthrough work acquired a status of foundational work of a new scientific field and earned him a title of “father of acoustics”. It was the first systematic description of the vibrations of elastic bodies.

The Unlikely Confidant

Once Shax took his leave, Teal deflated, stumbling till he was leaning back to rest against the nearest wall. The discomfort in his ember lingered and he was sure now that it was something either emotional or in his mind as nothing was erroring in his systems. Along with that discomfort was also the lingering cold that crept in and settled under one’s plating that simply came from exposer from the void.

Peeling himself from the wall, Teal navigated to the washracks, standing under the stream of hot water, letting it slowly chase away the chill. He thought about what Shax said. He really wished he could speak to Shax directly but the thought of having 1408, ever present, ever leaning over Shax’s shoulder, always listening in, it turned him away from the idea. 1408 was a distraction he didn’t want right now.

He had questions he’d like answered. There were four beings he knew of that could give him answers. Shax and 1408 were, for the moment, out. He briefly thought of Tallulah but she was a wild and free spirit, a bit of a loose cannon. That left Tike, who had been encouraging of Teal’s questions and fairly straightforward.

He turned off the hot water, drying himself, feeling a bit more relax. Which was good because what he was about to do next was utter foolishness and he might as well be relaxed in the midst of playing a fool. He relocated to the commons room to a comfy couch with a cube of high grade because if you’re going down these paths, you might as well do so in comfort with a warm glow in your lines.

After taking a generous drink, he cleared his throat and tried to clear his mind as he thought of Tike’s name as well as spoke it several times, secretly grateful there were no witnesses to this.

GOM+ Imayoshi + Kagami's gf is super scared of thunder and lightning; both of them were already out on a date initially but there's a sudden thunderstorm and their gfs' freak out

Kuroko: Her knee bumps the table, causing the dishes to rattle in place, as the sudden boom of thunder reverberates through the room. Kuroko is quick to settle the plates and cups, assuring they wouldn’t tip over before he makes his way to her side. Inwardly, he’s thanking every higher power he can think of that he had decided to have a dinner date in the comfort of his home. It made it much easier for him to hold his girlfriend close and whisper soothing words into her ear.

Kagami: The short shriek that leaves her lips as lightning flashes outside, followed by the sudden black out in the movie theater, is enough to make Kagami tense. The two of them could practically hear the thunder bellowing outside—that’s how close the storm was. Beside him, his girlfriend has started trembling in fear. Feeling horrible about the situation, he hesitantly wraps his arms around her, trying his best to talk loudly over the sound of thunder.

Kise: A small yelp leaves his lips as he’s startled by his girlfriend’s sudden cry. Mind going into overdrive, Kise starts stumbling over his words as he tries to ask her what was wrong. Did something happen to her? Was she hurt? Did he do something bad on their date? It isn’t until a flash of lightning closely followed by a clap of thunder interrupts his questioning spout that he realizes the problem. Holding her face, hands over her ears, he promises to bring her back home to safety.

Aomine: The sudden appearance of a storm is annoying and Aomine is quick to grumbling about it as he and his girlfriend walk home hand in hand. When a flash of lightning crosses the sky and her grip tightens around his fingers, he turns to her in confusion, wondering why she’d stopped walking. The tears in her eyes are enough to shock him and he’s quickly throwing his hooded jacket over her, telling her to pull the hood over her eyes to shield herself from the lightning flashes.

Imayoshi: She’d wrung out her napkin completely, making it resemble a wrinkly mess sitting on the dinner table. Despite the lighthearted conversation he had been trying to keep going, Imayoshi could hear his girlfriend’s subtle whimpers. The storm outside was far, but it was coming their way and fast. Claps of thunder could already be heard. Calling the waiter over, he’d ask for the dinner bill and escort his girlfriend home, promising to stay with her during the storm for as long as she needed him.

Midorima: The shattering of her glass cup as she drops it to the floor causes everyone’s gaze to turn in their direction. Midorima can feel the tips of his ears turning red in embarrassment as he crouches down to help the waitress clean up the broken mess. Glancing up to his girlfriend, he notices her distant gaze on the clouds outside. She was pale and afraid. Forgetting about the glass mess on the floor, he goes to her side, offering to take her home before the storm could get worse.

Murasakibara: Flinching as the thunder rolls on outside, Murasakibara takes the final bite out if his side of the shared dessert. Normally, he’d start stealing bites off his girlfriend’s side since she often ate slower than him, but as he glanced up to gauge her reaction, he notices her tightly shut eyes and fearful whimpers. Asking their waitress for a takeout box, he’s quick to pack up the rest of their dessert before taking her home. The entire way there, she’s engulfed in his oversized jacket.

Akashi: Guilt started to eat at Akashi the moment he heard his girlfriend shriek in fear of the thunder and lightning. He had known a storm would be on its way, but had been too blindsided by upcoming events of their date that he had overlooked her fear. Calling his driver, he’s quick to usher her into the limo once it arrives. The silence inside is welcoming and he simply instructs his driver to go around the block a few times until he eventually lulls her to sleep.

Chanyeol tapped his fingers against his wooden work desk. Things were getting more and more complicated ever since and all he wanted to do is get it over and done with. Get over and done with you. He knows very well that you were a huge part of his past and present but he couldn’t get a full grasp of it. After that night, he was restless, way restless than he had expected himself to. True, he wanted that to happen but his heart was still aching after a week and he needed clarity and closure., Period.

“You look a little restless today, my dear brother.” Chanyeol’s sister comments as she settles a plate of spaghetti in front of him.

“Oh,” He snaps from his thoughts and pushes his chair further into the table. “I was just thinking about work.”

She arches her eyebrow, amused.

“You never think about work, at home.” She adds. “Come on, spill the beans kid.”

“I broke up with (Y/N).”

“You did what?!” Chanyeol flinched at the sudden rise in her tone.

“Geez, I came for supper and I feel so attacked right now.” He laughs.

“Believe me, I am one muscle away from hitting you.” She replies. “Why did you do that?”

“I didn’t get the final say, she did.”

“I’m pretty sure you did something.” She rests her elbows onto the table and gazes at him.

“I made Baekhyun talk to her.”

“Of all people? You know how Baekhyun is with words, Chan!” Indeed, Baekhyun was terrible in putting his words in nicely (or sometimes politely) to people but Baekhyun was the only friend at that point of crucial moment he needed.

“Well, whatever, it’s over anyway.” He gives up on speaking another word to his sister and digs his fork into the strands of his spaghetti.

“You know, Chanyeol, I know you don’t remember but,” She pauses as she wipes her lips with a piece of thin napkin. “When you were with (Y/N), you had always try your best in whatever you do, anything for her you would kill to get, cut the chase, I’m just saying that maybe you should give your relationship with her a second chance?”

     The table was set, a centrepiece of candles in the middle, tealights strung along the room to add to the already romantic glow. Rose petals were settled all along the table, scattered on the floor, anywhere she could get them to add to atmosphere.

     She worked on getting the dinner to the table, trying not to trip over herself while carrying the multiple trays and plates, testing her abilities in balance and grace all at the same time. Virgo was not necessarily the most graceful of demons, but for what she lacked in that department she made up for with her charm and humour. 

     Settling the trays and plates down on the table, she adjusted herself, brushing long blonde curls over one shoulder and making sure she at least looked somewhat presentable when she heard the door open.

Just after 10 the next morning Link let himself into the apartment. Knowing that Jude’s fridge was practically empty he’d came armed with supplies and spent the next 20 minutes making breakfast. He wasn’t the best at cooking but the bacon, sausage, eggs and toast looked somewhat edible. After feeding Spike and getting him settled he put the plate on a tray with some coffee and made his way into the bedroom. Resisting the urge to kiss Jude awake he gently shook him. “Comeon, Wake up sleepy head. It’s breakfast time.”
