Resolution Effects on Ocean Circulation

The Gulf Stream current carries warm, salty water from the Gulf of Mexico northeastward. In the North Atlantic, this water cools and sinks and drifts southwestward, emerging centuries later in the Southern Ocean. Known as the Atlantic Meridional Overturning Circulation (AMOC), this circulation is critical, among other things, to Europe's temperate climate.

I occasionally wish to reach out to old friends/acquaintances I haven't spoken to since high school/some other even earlier time in my life, but I have SOOO little social energy even for required tasks (like making dr phone calls or etc), I never have any leftover for extra ones, and it would be very odd to message someone I haven't spoken to in like 5 years out of the blue but then take 4 entire months to respond back lol.. My natural curiosity with nostalgia/collecting details of the past/etc. (literally if I were born a little earlier I would definitely do scrapbooking or something lol) is very strong, but, alas, not strong enough to beat out the Social Issues Demons apparently

How do I put what's in my head onto the page? Is it always hard?

Hello!

If you're asking me how to make the writing live up to the fantasy, just remember: writing isn't a transcription service, it's an art form.

Writing isn't thinking, but between you and me, thinking isn't that great anyways. It's like singing in the shower. Thinking needs to be translated through a skill like writing before it'll make a good scene.

Creation is choices and actions, not recreation. Let me give you an example: I crocheted my dog recently, and I didn't aim to perfectly recreate my dog in tiny crochet form. Instead, while I crocheted, I converted her into a small character with plushie proportions. She had all her recognisable features and was a pretty good crochet dog, checked all the boxes, Dad was happy. But the little crochet dog didn't look exactly how the subject did, sat there wagging on the rug. That's because I wasn't trying to copy her. I was trying to crochet her. In the same way, I don't transcribe my daydreams, I convert them into writing form, and that's 90% less frustrating and 100% more possible.

As for whether writing remains hard forever, yes and no. Writing becomes easier with practice the same way anything does, but it gets harder as you naturally challenge yourself to write better, like a bodybuilder increasing the weights. But if you stop expecting writing to come out 'correctly' and instead lose yourself in the process, you won't feel the dead ends, you'll be too busy finding solutions and thinking on your feet -- you'll be in the zone.

I just wish I knew how to do that on command!

any time i see the live action how to train your dragon clips i get so violently fucking angry i hate live action remakes of perfectly good films so god damn much

like "ohh cartoons are for babies i cant watch movie unless its hyperrealistic" maybe LIVE ACTION REMAKES are for babies. maybe you dont deserve how to train your dragon if you cant enjoy the animation as-is. i will fucking kill you

Grace Hopper was born on December 9, 1906. An American computer scientist, mathematician, United States Navy rear admiral, and one of the first programmers of the Harvard Mark I computer, she was a pioneer of computer programming who invented one of the first linkers. She was the first to devise the theory of machine-independent programming languages, and the FLOW-MATIC programming language she created using this theory was later extended to create COBOL, an early programming language still in use today.

A Dash of Angst ...

- "it'd be a lot easier if I actually cared as little as I pretend to."

It was hard to not care for someone. Especially as an AI whos whole purpose was to be an aid.

An aid for someone who—quite frequently—could be a total jerk to everyone, except for her.

Miguel O’Hara.

It’s not like she wanted to care about him so deeply. She shouldn’t be able to, in theory. But somehow he gave her emotions, an angsty virus gone wrong, and suddenly everything around her seemed to light up.

Now, instead of mimicry, she could actually feel and interact with emotions. This would be lovely, if not for the weakness that came with it.

So, she had now taken it upon herself to fake emotions. Or rather—fake the lack of emotion.

And it had been going well—for the most part—until a freak accident gone wrong had her scrambling, mind frantic and frayed, as Miguel lay in front of her, wheezing with his hand pressed to his side.

This wasn’t how the mission was supposed to go. It was supposed to be an easy in and out, and yet the universe just had it out for every Spider-Man to never have it easy.

And Miguel was no exception.

Backup had been called minutes ago, but there was no blinding portal appearing in front of the two to save the day. She was sure that she had popped a fuse or two back at HQ with how stressed she felt right now.

A pained groan from Miguel brought her back to the land of the living and she materialized next to his head, her anxiety painted across her face.

“Do you know how bad it is?” Christ, she’s never been so stupidly worried before.

Miguel opened his mouth to respond, but instead closed it just as fast, his canines clacking together in a grating manner. His face pulled taut and his fingers clenched tighter over the gaping wound in his side.

“LYLA-“ Miguel breathed out, his voice coming out raw and raspy. She didn’t look at his face—couldn’t—instead looking down at his wound, his blood leaking out and mixing with the dirt.

A reminder of his mortality, she mused.

“LYLA.” Miguel repeated. And this time, LYLA looked up, fully taking in the look on Miguel’s face.

He looked to be in so much pain, and yet, an almost amused expression was faintly to be seen. LYLA scowled at that, vowing to scold him later for daring to smile while he was clearly in mortal danger. (she didn’t end up scolding him + had yet to learn that smiling or laughing in danger helped diffuse tensions)

“Why are you smiling?” LYLA frowned, her fingers flying over her multitude of chats to spam for backup, yet her eyes never straying from Miguel’s face all the while.

“Because you look worried,” Miguel hissed as he accidentally dug a finger into the wound, blood trailing along his fingertips.

LYLA puffed her cheeks out, putting away her chats and materializing next to the wound so she could check on how bad the bleeding was.

“It’s because I am worried.”

Miguel raised an eyebrow, moving the hand to let her see the damage easier. “It’s almost as if you cared.”

Was that teasing in his voice? LYLA glowered up at Miguel, “Well, it’d be a lot easier if I actually cared as little as I pretend to.”

Miguel opened his mouth to retort, but by how luck would have it, the portal opened behind them, Jessica and Peter coming out together with a small gaggle of Junior-Spiders following.

“Sorry we are late!” Spider-Terra exclaimed, peeping out from behind Spider-Punk. “There was an issue with the watches.”

LYLA nearly sighed before realizing there was no need for her to show her exasperation to a teen, and instead turned to the two adults.

“I’m not sure of the damage, but he’s still bleeding out from a massive hole in his side, there’s probably a broken rib, and I’m thinking some major bruising to his lungs.”

Peter quickly took over Miguel for her, promising LYLA that he’d stay with Miguel in the infirmary so she could dissapear to go handle any issues in the society that had piled up while the two were on the mission. (Jessica took the juniors to go handle the anomaly)

The day after, when LYLA went to visit Miguel, he didn’t bring up her words, instead asking about any paperwork that needed to be done.

LYLA wasn’t sure if she was relieved or not about that, but decided to let it be in the past and change her future to allow it to be a little more caring.

Venus Flower Basket Sponges

Venus flower basket sponges have an elaborate, vase-like skeleton pocked with holes that allow water to pass through the organism. A recent numerical study looked at how the sponge's shape deflects incoming (horizontal) ocean currents into a vertical flow the sponge can use to filter out food.

These photos are from the air flow simulation I did yesterday, to find out what impact the wind would have on the structure of the identification buoy. I recorded the animations to make it easier to analyze.

It was fun to do this, I discovered that I can make several different types of fluids, which could be useful in future projects. The article is almost ready, along with the boat and buoy codes.

Here are the charts with results generated from Solidworks:

Generally I don't do this, but I'll put the translation of the analysis I put in the article here, maybe it can help someone.

Although it is not common to carry out engineering tests in this specific context, we chose to conduct an analysis dedicated to aerodynamic conditions, aiming to understand the effect of wind on the structural integrity of the buoy. To carry out this study, we used Solidworks, making use of the fluid simulation system incorporated into the program.

Initially, we modeled the buoy structure, assigning specific materials to each component. Subsequently, we establish the necessary boundary conditions to faithfully simulate the behavior of the structure in real conditions. In the next step, we created surfaces that represent the wind pressure in the region where it impacts the buoy, and defined the area in which the wind pressure would be applied. The application of wind loads and adjustment of analysis settings were carried out using the “Flow Simulation” tool.

This process allowed an accurate representation of the aerodynamic conditions on the buoy structure. Additionally, we adjust relevant parameters for the analysis, ensuring a comprehensive approach.

The simulation execution culminated in the generation of a comprehensive report, documenting the results obtained. The interpretation of these results provided valuable insights into the structure's performance under simulated aerodynamic conditions. This engineering test highlighted the importance of considering aerodynamic conditions when assessing structural integrity.

It is possible to highlight some fundamental reasons for the importance of this analysis, such as the assessment of structural integrity, assessment of operational safety, design optimization, which can result in savings in materials and manufacturing costs.

The Montagem_boia.SLDSAM model was configured with standard parameters, carrying out 57 iterations to achieve convergent results. The mesh was defined with basic dimensions (Nx = 40, Ny = 9, Nz = 17), and boundary conditions were established to represent the fluid environment of interest.

The physical time interval considered was 0 seconds, and the CPU time required for the simulation was also recorded. The simulation results revealed an interesting distribution of fluid properties and flow characteristics. The total number of cells in the mesh was 7626, all occupied by the fluid. Among these, 1106 cells were in direct contact with solids.

The mesh dimensions (X,Y,Z) indicated a significant extension of the model, with minimum and maximum variations in each direction. Analysis of the velocity field revealed a range of [0 m/s; 7,510 m/s], indicating different flow regimes within the simulation domain. The pressure varied between [101294.37 Pa; 101430.23 Pa], with a reference pressure of 101325.00 Pa. The temperature remained relatively constant, with values ​​varying from [293.20 K; 293.21 K]. The fluid density showed a minimum variation, within the range of [1.20 kg/m^3; 1.21 kg/m^3].

There was no consideration of factors such as heat in solids, radiation, porous media and gravity to simplify the model to meet the specific objectives of this simulation. Based on the analysis of the images obtained, the reduction in wind speed becomes visible when facing the structure of the identifying buoy.

Notably, the average wind speed in São Paulo, situated at 25km/h, is insufficient to cause damage to the aforementioned structure or to displace it from its original position. It is also worth noting that, when encountering the obstacle represented by the buoy, the wind flow tends to bypass the structure mostly from above, to the detriment of the sides.

This observation suggests an effective resistance of the buoy to direct wind impact, contributing to its stability and structural robustness. The results clearly indicate that the structure's resistance to wind action is remarkable, since the force exerted by the wind did not reach levels that would compromise the integrity or stability of the configuration.

The solidity of the structure in the face of these conditions suggests that the design presents a robust and adequate response to the expected wind loads.
