this week i'm cheating a little and posting a large portion of the (now published) rewrite of chapter 4 from Cycle of the Serpent! i've posted up to chapter 6's rewrites thus far, and should have 7 and 8 rewritten and updated soon. this chapter features the trio heading to Bleak Falls Barrow, from Emeros' point of view <3

  The road twisted narrowly from the bridge, angled and sloping, lined with strange stones. Some appeared intentionally arranged and stuck in their ways, watching the young elves through every crack in their worn surfaces. Some were more incidental, shrugging off the weather. Some appeared to be severed off from old pillars, smoothed by the many years gone by and wondering where their extra heights had gone. Emeros kept an eye on the greenery, on the land that gradually grew more and more distant, the town that faded from view as the three marched up the pathway.    The gradual drop in temperature intensified itself the further they got from Riverwood, the dusting of snow that cropped up at the tops of new and unfamiliar trees still preserved this far into Last Seed, and by the looks of the powdery texture, had fallen not too long ago. The pathway in its drastic angles took on more danger, as ice collected at the bases of the evergreens. Meticulous with their footing, the three carried themselves up the path to the barrow, careful to examine each stone they pressed their boots against.   Emeros had been in various ruins for any number of purposes over the years. He'd adventured into Ayleid ruins in his earliest days in Cyrodiil, never leaving the first chamber if he could help it, collecting samples of the mosses and fungi that grew within. Sometimes, he'd find an interesting vine, or a plant he hadn't recognized from the surface world. He'd take great pains to preserve them until he could examine them safely, testing new potions and properties, inspiration his guide in every experiment. If he combined this amount of imported trama root with this amount of the unidentified fungi, placed it in an already known potion recipe, how would it change the effects? Would it create something to heal, or to harm?    What new concoctions could he make with the native flora of Skyrim? And maybe, if luck was on his side, would he find something previously unknown in this ancient place?

  The trio trudged onward, the wind whipping at their faces, brushing flakes of snow like tiny spears against their skin. The cold was one factor all of them wished they'd prepared more thoroughly for, but if they were going to explore this place and bring back the claw, then they had to keep going. Day had long since crest the mountains, rising above them in a lustrous sheen of blue, light bleaching the landscape before them a harsh, eye-pulsing white.    As they turned their eyes to the top of the mountain, a strange stone tower came into view. Weathered by the ages and capped with snow, the sight alone sent shivers through the Bosmer. Emeros hissed for the others to get down, snagging the other two by their tunics, hidden behind a massive stone. When Wyndrelis was about to quietly protest, Emeros pressed a finger to his own lips and then gestured to the tower. The other two Mer looked.    A figure marched the slim, dreadful bridge from the tower to the mountain, back and forth at an easy pace. Bandits. And they'd almost walked right into their line of sight.    "What do we do?" Athenath asked in a hushed tone, partially unsheathing their newly acquired sword. Wyndrelis pressed his spine to the rock they huddled behind, with the spare, occasional glance to the figure.   "Emeros, you have a bow. Can you use it?" Wyndrelis asked in a hush, Emeros already nocking an arrow.   "I've been hunting in Valenwood since my childhood," he answered, taking aim. He shut one eye, lined up his shot, and stilled his breaths.   "Not yet!" 

  Emeros startled at Athenath's hard whisper, grip on the arrow tighter. He slid it forward, letting the string go slack. He cursed under his breath as he turned to Athenath, brow quirked and eyes narrow. The Altmer pressed palms to the sides of Emeros' head, and as the alchemist was about to protest, his eyes landed on a detail he'd missed.   Up the incline, pacing back and forth before them, a bandit that no one else had seen.    Two targets, then.   He looked to his companions, then to the bandit. This would come down to timing, by his own analysis. If he took one out without the other noticing at first, it would give him a few seconds to get another arrow and put the last one down. Then, they could safely traverse the mountainside. He gave Athenath one last look, this time the slightest gleam of a grin on his lip, not daring to speak too much. He knelt in the snow, nocked his arrow, and waited.   When the bandit at the fortress had their back turned, he fired. This arrow pierced through a weak spot in the incline-bandit's armor, injuring them, stunning for a moment before Emeros got another arrow through their neck. He shifted his attentions to the fortress-bandit, who dashed to the crumpled body of their companion. He fired, and this shot went clean through the torso, spearing the upper chest, likely a lung, if he guessed from here.   "I think that's all of them." Wyndrelis rose from behind the stone, wiping the snow from his trousers as he grabbed his belongings. The three rushed to the bodies, and as they confirmed that the bandits were dead, Athenath began to rifle through the pockets of the corpses. Emeros sputtered protests, but as the Altmer produced some gold, some new arrows, and a set of leather gauntlets, he found himself complaining much less. They handed the leather gauntlets to Emeros, then stood and stretched.   Wyndrelis thought something over for a moment. Then, he knelt, slowly undoing the fastens and buckles of the much warmer-looking armor the bandits wore.

  "What in Oblivion are you doing?" Emeros hissed, Wyndrelis looking up at the other momentarily before returning to his task. Athenath joined in, helping Wyndrelis lift the fur-lined piece from the first body before they descended on the second.   "It's not like they need it, and we can't run around looking like soldiers forever," Athenath retorted.    Wyndrelis agreed, pulling the first set of armor to himself. He shifted his gaze to Athenath, brow knit. "Tell me, why did he get the gauntlets?"   Athenath shrugged as they looked up to Emeros momentarily, before handing over a soul gem they'd dug out of a bandits pack Dunmer, who tucked it into his pocket. "Archers usually need them, right? Something about the string?"    Emeros gave a small, apprehensive nod, and even though his features were marred with the shock of the pair descending upon the dead like carrion birds, he figured that they had a point. It wasn't like any of them could afford to buy armor right now, and none of them needed to run around dressed as Imperial soldiers in potentially-hostile land.   He donned the gauntlets. The leather fit well over his fingers, and most importantly, they were warm. The other two bundled up fur and leather armors, before they stepped into the tower, nudging their steps with extra caution over the frail bridge. Rifling through drawers gave them more gold and a place to toss the Imperial armor without much worry. They'd have to hurry, though. Taking too much time here meant that they were both wasting time they could be using to get in and out of the barrow, and meant that it gave the bandits more time to come find them, and the bodies of their compatriots.    Once Athenath and Wyndrelis had donned the bandit armor - "Well, you didn't seem to want it," Wyndrelis shuffled the explanation awkwardly out - the three inched back to the stability of the mountain, the wind whipping furiously around them. The steep pathway lead further upwards, to the enormous stone arches and sharp angles of the ancient ruins. Stairs slick with ice rose up to a gigantic platform, the air thick with worry. Something innate gnawed at Emeros, the warnings of old friends from northern High Rock not to head into similar structures rumored to line the furthest reaches of the province murmuring in the back of his mind. He shook them away. This was not the same. This was something he'd said he'd do, and he would bloody do it. 

  "We should be on our guard. Two bandits means there's probably more, and if we're not careful, we'll walk right into a trap."   "Or another ambush." Wyndrelis joked dryly. Emeros rolled his eyes, but still, he laughed.   "Or another ambush." He repeated, grinning.   The dark, snow-covered stone gathered in points towards the sky. They made a calculated approach, the three in a line as they focused on any potential movement from the structure. When bandits emerged from the shadows of the ancient, high-arched ruins, the caution came in handy. One of them fired arrows down at the three, barking at them to leave with their lives or they'd gut them like a purse. Athenath flinched and dodged the barrage, Wyndrelis holding up a ward, magicka pouring into his fingertips, collected in arching light. He pushed forward, Emeros using the ward's cover as a shield to fire his own arrows behind. This time, it took several shots, moving as he fired at a simultaneously moving target. He cursed and hissed as he fired at the figure until he saw them kneel, then another, then down.    A second bandit charged with a war axe, Wyndrelis using his other hand to fire a bolt of lightning that struck through the middle, jarring the bandit enough to give Athenath an opening. The Altmer charged, bashing the hilt of their sword into the back of the bandits head, hoping they'd only knocked them out.    The final bandit rushed Emeros, nearly swiping their blade into him. The Bosmer ducked down by an inch, bringing his own sword from its hilt and striking them through the chest, pushing it as deep as he could muster in the moment. The armor gave way as the bandit struggled to block, a fight that lasted mere seconds and ended just as quickly. The three caught their breaths, snow now pelting down at them from the pale clouds above their heads. Whatever world they'd just ambled into gave them one hell of a welcome.   Better than the one they'd all received at the border, Emeros thought as he tugged his cowl tighter, thefurious winds knocking the fabric off his head every time he attempted to right it. Grumbling, he left it around his neck as a scarf, and trudged up the final stairs to the doorway of Bleak Falls Barrow.    Adrenaline throttled their veins. The Mer looked between one another. Then, Emeros slowly pushed open the door to the barrow, into the dim chamber that would seal their decision. No going back from here, the decision decreed. No turning back.

Proba-3 will constantly measure Sun's energy output

Proba-3 is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3's Coronagraph spacecraft observe the sun's faint surrounding atmosphere, its disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3's Occulter ends up facing the sun continuously, making it a valuable platform for science in its own right.

The sunward side of the Occulter therefore hosts a dedicated instrument that will maintain a continuous measurement of the sun's total energy output, known as the total solar irradiance, which is a essential variable for climate studies.

The shoebox-sized Davos Absolute Radiometer, DARA, has been supplied to the mission by the Physical Meteorological Observatory Davos, PMOD, in Switzerland.

"Researchers used to talk about the 'solar constant' but in fact it is always changing slightly," explains Wolfgang Finsterle, DARA Principal Investigator at PMOD. "And it's essential to keep track of the total solar irradiance, because it is the dominant energy input to the surface of the Earth.

"It amounts to something like 99.978% of the energy available on Earth, including the conserved solar energy stored in coal and oil. It drives all the dynamic processes of Earth's climate, so even the tiniest variations are hugely significant."

The mountain-based PMOD has been studying total solar irradiance for more than a century, initially with ground-based instruments and then from the 1970s deploying space-based radiometers to acquire a continuous dataset. The World Meteorological Organization has mandated PMOD as the World Radiation Centre to calibrate radiation measurements across global UN monitoring programs.

Wolfgang adds, "Total solar irradiance varies along with the 11-year cycle of solar activity, and one of the most obvious ways to look for long-term energy drift is to compare total solar irradiance between consecutive solar minimia.

"This requires a long time-series of data, ideally coming from multiple instruments because single radiometers will undergo degradation in sensitivity from the hard ultraviolet in the sun's rays they are continuously exposed to. That said any degradation is very gradual: the radiometer aboard the ESA-NASA SOHO solar observatory for instance, which was launched in back 1995, is still working satisfactorily."

DARA's basic operating principle is simple. The radiometer possesses a 5-mm diameter cavity made from black-painted silver, possessing low temperature emissivity. For 15 seconds at a time, sunlight warms the interior of the cavity, then a shutter blade automatically closes at its entrance.

For the next 15 seconds, electric heat maintains the cavity's previous temperature—and the energy needed to maintain this temperature is extrapolated to the unit of total solar irradiance, which is watts per meter squared.

This process continues for the entire lifetime of the instrument—the actuated shutter design employed in DARA has been tested for millions of openings and closings in PMOD's vacuum chamber.

"DARA is an improvement on previous radiometer designs with an optimized cavity design to minimize unwanted straylight and a multi-channel measuring system for self-calibration," adds Wolfgang. "This generation of instrument also possesses a fully digital control loop, allowing the possibility of experimenting with higher frequency observations.

Two versions of this radiometer design have already flown, notes Werner Schmutz of PMOD, who oversaw its development: "A compact version called CLARA flew on Noway's NorSat-1 CubeSat in 2017, remaining operational to this day, while a previous DARA is serving aboard the Chinese FY-3E weather satellite, launched in 2021. So we have high confidence in the design, which can operate whenever the Proba-3 Occulter is pointed at the sun within half a degree of accuracy."

The main difference between Proba-3's DARA and previous radiometers will be its very elongated orbit, which will carry it 60 000 km above Earth's surface. DARA can automatically adjust to slight changes in the size of the solar disk based on how far it is away—which are also due to Earth's yearly elliptical orbit around the sun. All the radiometer needs to know is its position in space and its data gathering compensates for the shift.

who: @meredythrowan​ where: one of the many maesters chambers within a wing of dedicated care and treatment in the castle of highgarden

the echoing footsteps of the lady of the arbor bounced off the towering marble walls, bathed in the colours of the illuminating stained glass windows. the sun was sinking beneath the currents of the mander outside, and she was based in hues of orange and red alongside the new princess of the westerlands - whilst they painted her golden, she only saw meredyth as blue. her footsteps paced and paced back and forth the end of a bed; a part of her wishing she had just summoned a maester to the florent apartments and yet during their evening walk in the gardens, the very same thing had occurred.

the spreading of numbness in her knees, feeling as she suddenly could hardly see the world around her for the way it blurred and smoothed so quickly. this time she had managed to sit herself amongst a bed of roses, no doubt looking somewhat peculiar to the guests that walked through the sunset that illuminated the gardens of highgarden. the maester's wing was closer than returning to the florent apartments, and whilst lucrezia insisted she would return there and call upon a maester, meredyth rowan had insisted on them going directly to the wing and seeing a maester immediately. 

apparently her face had gone strikingly white, all too suddenly; whilst coloured had returned to her cheeks now, there was sudden moments where she felt as though she could not feel anything below the soles of her feet.

the maester had asked her multiple questions, inspected her condition and her temperature; sending a septa to inspect her bust and her hips, asking questions that were more personal in details. questions regarding her cycle, when she had last bled. the questions made it clear what was being suggested, though she were surprised; perhaps as a result of seeing her mother's struggle with pregnancies, carrying and becoming, she did not think such a thing would happen so soon. still, it could only be confirmed should the test carried out upon bags of wheat and barley show any evidence, something the maester was overseeing and inspecting now.

she was thankful meredyth was here, looking over at the woman who sat on the edge of her bed. as lucrezia did her buisness on the opposite side of the divide, meredyth was there to help provide her some relief during the tense moment where she felt her hands were clammy. and now, she waited for what the maesters would determine, looking over at mimi whilst she paced back and forth. "do you think this will take long?" she asked, moving a strand of her chestnut coloured hair from her face.

Man, I am 2 for 2 on fun conversations with ~randos in my neighborhood.

Waiting in line to get an afternoon coffee, I overheard two men, a beared white guy and a goateed Asian-American guy, talking about neurodivergence and then military IQ tests.

Usually, when I hear people discussing IQ tests in public, at least if they're dicussing their own IQ scores, I tentatively bin them as weird dick-measurers. But...this felt different, and so I broke into their conversation.

I mentioned that Bobby McNamara, our secretary of defense under LBJ, expanded military induction to low AFQT scorers during the Vietnam War, which resulted in many of those low scorers getting killed on the battlefield due to inability to understand battle conditions and difficulty following complex directions, and how this was widely regarded as awful public policy by those who understood it.

One of the men I was speaking to said this didn't surprise him; he and his conversational partner had been in a program where "NUKEs" (Naval nuclear technicians, who were drafted from the top echelon of AFQT scorers) were trained alongside low test performers, and the on-the-job differences between the two cohorts were really obvious. Everyone who works on a US Navy submarine, all of which are nuclear-powered, is a high AFQT scorer because there's lots of technical material to absorb in training, delicate chemical tests need to be carried out, complex safety protocols need to be followed, etc., and AFQT scores statistically predict competence in such roles well.

The mention of nuclear technical programs piqued my interest, so I asked him more. He said he received some training on reactor operation but was never stationed on a sub. Then I asked him if he was familiar with the Air Force's nuclear-powered aircraft program. That got him visibly excited, which got me excited. We talked about the molten salt coolant and the fuel dissolved in it.

The Asian guy asked how the reactor was used to propel the plane. Racking my brain, I said the reactor creates a heat gradient, which has to drive a propeller housed in an engine cowling. I was missing a vital detail that the hot coolant runs though a heat exchanger positioned in the compression chamber; this raises pressure, and a turbine uses the pressure to drive a shaft to compress the incoming air (which, I presume, raises efficiency). Whenever you have a temperature gradient, I said, you can harness it to do mechanical work—at once true and a punt.

I was gonna bring up reprocessing when the Asian guy asked if damage to the aircraft reactor would turn the aircraft into a dirty bomb. The white guy said the molten salt reactor is inherently safer than widely-used light water reactors because it's kept at atmospheric pressure and is already liquid so cannot melt down. There's nothing to disperse the material. Plus, said the white dude, there's far less waste (mid-long lived radionuclides, all of which are actinides, are burned off during operation).

Very excited now, I brought up the suitability of molten salt reactors for use with the thorium fuel cycle that breeds thorium-232 into uranium-233 for fissile material, making better use of a more abundant material with less proliferation risk. The white guy looked very happy.

He asked if I knew all this because I was interested in a military career. "Not particularly," I said, "I'm just a technology enthusiast. I've been on a nuclear engineering kick for the past couple of months." I had a brief flash of fear that I came across as a foreign intelligence agent.

They said they needed to head out. I asked them if they lived in the area. "Yeah, we live around here. We come by in the afternoon every so often for coffee."

Though I'm happy I'll be moving soon, I realize I'm going to miss this area. Why didn't I start meeting these people three years ago, damn it? Also, moral of the story: talking to people talking about IQ tests may lead to nuke conversations, which are fun.
