#frame dragging

[whats-in-a-sentence]

The effect is called frame dragging because from the point of view of the asteroid – from its frame of reference – it isn't being whipped around at all. Instead, it's falling straight down along the spatial grid, but because space is swirling (as in Figure 14.1) the grid gets twisted, so the meaning of "straight down" differs from what you'd expect based on a distant, nonswirling perspective.

If the experiment is successful, it will be one of the most precise confirmations of general relativity ever achieved, and will provide the first evidence of Machian effect.²

2. In the four decades since the initial proposal of Schiff and Pugh, other tests of frame dragging have been undertaken. These experiments (carried out by, among others, Bruno Bertotti, Ignazio Ciufolini, and Peter Bender; and I. I. Shapiro, R. D. Reasenberg, J. F. Chandler, and R. W. Babcock) have studied the motion of the moon as well as satellites orbiting the earth, and found some evidence for frame dragging effects. One major advantage of Gravity Probe B is that it is the first fully contained experiment, one that is under complete control of the experimenters, and so should give the most precise and most direct evidence for frame dragging.

SAVE ME YOU, SOMEBODY SAVE ME YOU — I’M YOU’RE SCREAMING FOR A LIFE THAT I YOU CANNOT HAVE

I really wanted to redraw the part of s01e14 where Starscream grabs Knock Out’s face but in reverse… And since I posted fluff for day 13, I thought an edgier illust would be a fun contrast! I think they do love and care for each other despite being bad (SS) or weird (KO) at showing it, but both of them are still Horrible people with Problems so there’s also a lot of uncertainty and resentment between them.

Given their interactions in canon I feel like Knock Out has more to seethe about than Starscream (who rarely got mad at KO directly and more just doesn’t know how to not take his stress out on other people), but I don’t think all of KO’s grievances are valid LMAO It felt to me that he caught feelings (platonic and/or romantic), and when that energy wasn’t clearly reciprocated, his petty and narcissistic ass took it very personally.

sorry let me rant about downton abbey 10 years later

Thomas's conversion therapy plot pisses me off so much. firstly, it's incredibly out of character. he never wanted to change to conform to society, he wanted the world to change to accomodate him. the man who said "it's not against the law to hope is it" and "I'm not foul, Mr Carson, I'm not like you, but I'm not foul" would NEVER

secondly, from a storytelling perspective, the only 'problem' is that he used infected needles. did we forget that Thomas was a sergeant in the RAMC? he knows how to sterilise needles and how to recognise and treat infection. this also shifts the blame to Thomas himself for getting sick and implies that the conversion therapy itself is harmless (Dr Clarkson says it's just saline solution)

thirdly, it's not historically accurate. I'm not an expert but conversion therapy was not at all common in the 1920s, even Sigmund Freud was against it. hormone therapy and chemical castration were barely developing let alone available to the public (I can't imagine what else the 'treatment' was supposed to be). the only practices that I can find evidence of were psychoanalysis and electric shock therapy

Thomas also mentions that he did electric shock treatment - if you really want to make a point about homophobia in the 1920s (and make Thomas suffer as much as possible), show that instead. watching him be literally tortured for his sexuality would have been far more impactful than him just... looking sweaty for a few episodes

suddenly sitting up awake at 12am: i think thedas has a genre of memento mori types of paintings, where they put a skull in with some fancy still life stuff to indicate that the patron/artist is wealthy, but also Pious and thinking about Inevitable Death rather than material things (even though they're lovingly rendering all the silverware and expensive fruits and lace tablecloths or whatever)

BUT. since andraste is associated with fire, this is done by including like a lit candle or an urn of ashes or something in the composition, to show the piety and focus on the impermanence of life! i think this would be common in orlais especially. presumably tevinter is trying not to play up the "whoops we turned the saviour into a burnt kebab :)" angle in their religion, so they'd have... idk. a knife or something? to indicate the sword of mercy as the pious symbol of death rather than the fire itself?

WolShtola Week 2025 - Day Two - Fell first/Fell harder

A gradual acceptance of ones own yearning heart.

A sudden clarity to long harboured, deep affections.

The moment shared across two points of time.

This is known as frame dragging and implies, for example, that an asteroid freely falling toward a rapidly rotating neutron star or black hole will get caught up in a whirlpool of spinning space and be whipped around as it journeys downward.
