    So, I was supposed to be a twin, but my twin was absorbed in the womb, which is known as "Vanishing Twin Syndrome", but i have a couple questions about this

    Jump

  • Why would OP’s mother bring up the ultrasound in the first place if she were deliberately trying to conceal anything?

    I could see the twin being stillborn and the doctors thinking it was easier to tell the mother it had “vanished”, though.

  • What if we got Ea-Nasir wrong?

    Jump

  • Maybe it was the equivalent of a competitor making a bunch of fake one-star Yelp reviews.

  • Denmark Rejects Trump’s Plan to Send Hospital Boat to Greenland

    Jump

  • Has Trump considered making the ship look like a big horse?

  • Westerners, what's your impression on the Chinese Diaspora? And what does the people around your area of residence think of the Chinese Diaspora?

    Jump

  • I live on the edge of my city’s Chinatown (Oakland, California) and it’s an important part of the local culture. I’ve lived, worked, and studied with Chinese/Taiwanese nationals, and if they weren’t there I’d feel like something was missing.

  • The U.S. spent $30 billion to ditch textbooks for laptops and tablets: The result is the first generation less cognitively capable than their parents

    Jump

  • I suspect that if Gen Z designed their own cognitive tests, their tests would determine that we older generations were less cognitively capable than them.

    The reality is that every generation adapts in different ways to fit their own cognitive circumstances, and one generation’s metric is at best an imperfect match for another—“cognitive capacity” can’t be objectively measured.

  • Why does cats (and similar animals) can live with the exact same food every day, but we (humans) need a variety of food to survive?

    Jump

  • Cats and similar animals are adapted to specific environmental niches, but humans are generalists. One of the drawbacks of being generalists is that we’re not specialized enough to fully subsist on any single food source.

  • What books have a lot of useful information should I get? (I mean like a Wikipedia thing with vast knowledge, but non-electronic.)

    Jump

  • Reading is a kind of trance. A state of modified consciousness as powerful as any drug. And we all know what drugs can do.

    Jump

  • Reading is a direct extension of oral storytelling, which is a defining human activity. So a better parallel would be to eating—and non-readers are the ones in an abnormal state, like being chronically malnourished.

    Marjorie Taylor Greene: "Americans want rich powerful pedos and rapists strung up on gallows, even if it collapses our government"

    Jump

  • She says that like collapsing the government wasn’t her goal all along.

  • Why is #FFFFFF white, but mixing red green and blue paint is black?

    Jump

  • I’m not sure I’m accurately visualizing exactly what you’re describing, but I know from experience working with a two-color offset press that the results are quite different if you print two colors in two passes vs one pass (in which the inks are combined on a “blanket” where they effectively mix together before being transferred to the paper all at once).

    In the first case, the result is exactly what you’d expect from a subtractive color model; but in the latter case, the mixed ink that ends up on the paper is no darker than the component inks. The hue is similar whether overprinted or mixed, but the saturation is reduced in the mixed example.

  • When boomers said they wanted to "protect children" from the media, they created MPAA ratings and the Parental Advisory stickers. When Gen X said they wanted to "protect children" from the media...

    Jump

  • Big tech CEOs aren’t creating the surveillance state, they’re just profiting off the demand for it.

    Also—politicians and cultural figures generally reflect the values of the groups they come from, but CEOs of all backgrounds just reflect the values of capitalism.

  • Why is #FFFFFF white, but mixing red green and blue paint is black?

    Jump

  • In theory mixing a bunch of those 3 colors together, you can eventually get down to black, in practice your pigments aren’t perfect

    This is a common misconception, but it has nothing to do with imperfections in the pigments. The real issue is that you don’t want each of your primaries to block a full third of the visible spectrum—you want each to block a narrow band of frequencies that overlaps as little as possible with the sensitivity curves of the other cone cells in your eyes, in order to produce fully-saturated colors. The tradeoff is that intermediate frequencies aren’t blocked by any of the primaries, which is why we need to add black.

  • Why is #FFFFFF white, but mixing red green and blue paint is black?

    Jump

  • Other comments are discussing additive vs subtractive colors, but that’s not accurate if you’re talking about mixing paints. Subtractive printing (CMYK) works by overprinting transparent inks, where each ink removes a different part of the spectrum. But mixed paints differ in two critical ways:

    • Paints are opaque, not transparent. Unlike subtractive inks, paint doesn’t invariably darken the color it’s painted over—instead it completely or partially replaces the underlying color.
    • Subtractive inks are applied to the substrate one at a time—they’re not pre-mixed and applied in one pass. If you mix paints before appying them, you get more of an averaging than subtraction or addition (so mixing primary colors gets you a medium brownish-gray instead of black or white).

    What are theory-consequences of probabilitywaves having 3 states: future=gas, present=liquid, & past=solid, in infoprobability-field?

    Jump

  • probabilitywaves have to exist IN something, therefore there IS a probability-field

    Probability amplitudes are directly derived (via the Born rule) from wave functions in quantum fields (electron field, proton field, etc.) That’s the medium probability propagates through—not a separate probability field.

    The phases of matter (solid, liquid, and gas) are derived from the relative strengths of kinetic energy vs various types of electromagnetic interactions, on a much larger scale.

    Time and information are derived from coarse-graining microstates into macrostates on a larger scale yet. Those are all pretty distinct processes.

  • Drinking 2-3 cups of coffee a day tied to lower dementia risk

    Jump

  • The primary outcome was dementia, which was identified via death records and physician diagnoses.

    If caffeine has enough of an effect to change a diagnosis or death record, that seems worth reporting in any case.

    And while it might be worthwhile to see if other stimulants have a similar effect, does it affect these results one way or the other?

  • Is the threadiverse abusing Likes and Dislikes?

    Jump

  • You express your like or dislike toward the sentiment expressed by the post, not the thing(s) mentioned in the post.

  • Is the threadiverse abusing Likes and Dislikes?

    Jump

  • As an example, imagine a post with a title like “AI is awful” (I’m sure many here has seen posts like that). A Friendica user could reasonably agree with the post and thus “Dislike” it. As in, they also find AI awful and they dislike AI, so they dislike the post, to show their disapproval of AI.

    I don’t believe dislikes are meant to function like that on any platform.

  • The Japanese flag is a to-scale map of the solar system.

    Jump

  • So the Japanese empire was just an attempt to fit the rest of the solar system on their flag?

    Maybe "CAESAR STABBED IN BACK BY BRUTUS AND CASSIUS" was just an ancient clickbait headline, and the actual event was a minor policy dispute instead of a literal assassination.

    Emerging niche clustering results from both competition and predation. (My takeaway: more species can coexist in an ecological niche if they have distinct predators.)
