  • With regard to arts and culture, what would you call the view, whether you agree with it or not, that "everything's been done?"

    Jump

  • If I had to coin a term, I’d call it “aesthetic ergodicity”.

    As in, a culture that keeps revisiting every combination of aesthetic parameters over and over with no long-term trend.

  • More Than This Many Hours of Sleep Is Linked to Early Death, Scientists Find

    Jump

  • scientists narrowed down a “sweet spot” of between 6.4 and 7.8 hours of sleep per night

    If you sleep less than that on weekdays and more on weekends, does it average out?

  • What's the biggest misconception you think many people have?

    Jump

  • Or that refusing to understand is a valid counterargument.

    What would you do if you found out your dad changed his name and went no-contact with his family years ago, before you were even born?

    Jump

  • It seems like you really want someone to tell you there’s a set protocol for all these highly specific scenarios you keep presenting, but they’re all contingent on the human factors you leave out.

    In practice it depends more on your relationship with the people involved than on a generic description of their actions.

  • Seems like the obvious next step would be to combine this with variable layer height to get a continuous range of intermediate tones.

  • California judges are testing a new AI clerk. You won't know if it's looking at your case

    Jump

  • Even if it worked perfectly... isn’t clerking the way future attorneys and judges are supposed to get experience?

  • Has/is there ever been a creature that reproduces with creatures of another species?

    Jump

  • Viruses, in a sense.

  • Having consumed some science fiction over the years, I thought of what if faster-than-light travel is invented and the consequences that could happen.

    Jump

  • Even moving with 10 times the speed of light, you still take “forward time” to move to your end point.

    There’s no such thing as speeds faster than light—the worldlines of objects with such trajectories are called “spacelike” instead of “timelike” for a reason. “Forward” and “backward” time is only defined for events within your light-cone, and trajectories “faster than light” are outside it. Whether events outside your light-cone are in your future or your past are dependent on your current reference frame, which you can change at will by accelerating—so spacelike trajectories have no intrinsic direction with respect to time.

    The thing about “moving with FTL from A to B” is that if B is far away, the event at B simultaneous with your departure from A will be highly dependent on A’s reference frame—a shift in A’s velocity will correspond to a shift in B’s timeline equal to (vx/c2)/√(1-v2/c2) (where v is the change in A’s velocity and x is the distance to B). And things are changing velocities with respect to each other all the time (e.g., for objects on earth due to the planet’s revolution and rotation around the sun), so the point in B’s timeline at which you’d arrive would be constantly swinging backward and forward in time.

    And the same is true for the return trip: a minor change in B’s reference frame can put your arrival back in A’s timeline at a point before your original departure.

  • Having consumed some science fiction over the years, I thought of what if faster-than-light travel is invented and the consequences that could happen.

    Jump

  • Anytime you move at a different speed, the definition of what time matches your current time shifts throughout the universe by an interval proportional to the distance—even if you’re just driving down the street, the time that matches “now” in your reference frame in a distant galaxy could change by years relative to what it was when you were stationary. Of course, you can’t actually see that happening, so the difference is just theoretical... as long as you can’t teleport to that galaxy faster than light.

    But as soon as you have any kind of FTL travel, it’s trivially easy to go back in time by warping back and forth between two moving endpoints.

    What are your thoughts on people who are against pacifism?

    Jump

  • I.e., “What are your thoughts on people who are against people who are against people who are violently against people?”

  • Lawmakers Advance Bill to Make Daylight Saving Time Permanent

    Jump

  • There’s nothing preventing businesses from changing their hours over time as well (and in the long run, I suspect they’ll eventually settle on the same physical hours regardless of whether we choose standard time or permanent DST).

  • Trump’s pick for surgeon general sells supplement with ingredient banned by Pentagon

    Jump

  • I agree—I’m drinking tea with some kava in it right now.

    On the other hand, from people I know who worked in Army medical I get the impression that soldiers will find ways to abuse anything they possibly can.

  • Trump’s pick for surgeon general sells supplement with ingredient banned by Pentagon

    Jump

  • For anyone who doesn’t want to read the whole article, the ingredient is kava root.

  • Lawmakers Advance Bill to Make Daylight Saving Time Permanent

    Jump

  • Permanent DST is equivalent to permanent standard time with business hours moved an hour earlier. I assume that standard business hours were originally set by businesses to maximize profits—so if permanent earlier hours are better for business than permanent standard hours, why didn’t businesses set earlier hours to begin with?

  • What is a "Paradigm Shift"? Are they even real or just marketing speak? If they're real, are they possible to predict?

    Jump

  • Yeah—Kuhn describes reading Aristotle’s Physics and being shocked at how nonsensical it was. Then he spent months going through it term by term, until everything finally clicked: Aristotle’s world has a fundamentally different ontology and causal structure that’s perfectly internally consistent, and in that world post-Galilean physics is wrong—as nonsensical as Aristotle’s physics initially seemed to Kuhn. And there’s no way to get from that world to this one without abandoning the former in toto.

    In Kuhn’s view, paradigms are like parallel, mutually-incompatible worlds that happen to share the same surface-level phenomena.

  • what country do you live in and what language was taught in your school?

    Jump

  • USA, too—Spanish and French.

    If we’d had a third language it probably would have been Chinese instead of German—the cultural influence of German was minimal in the part of California where I grew up.

  • Why does it feel like most art museums are for adults and most science museums are for kids?

    Jump

  • Most art reflects on cultural and historical contexts that kids might not be aware of yet.Most science museums are geared toward teaching scientific principles that kids are also less likely to be aware of.

    So art museums depend on existing knowledge, while science museums supply knowledge to those who don’t yet have it.

    When a judge tells the jury to ‘forget XYZ,’ how can the jury possibly do that?

    Jump

  • As individuals, they can’t. But as a group making a decision through verbal discussion, they can exclude the information from the deliberative process. At least to their own satisfaction, they need to construct a justification for their verdict that doesn’t rely on the forbidden evidence.

    The Lord of the Rings spinoff the world needs right now isn’t Rings of Power or Hunt for Gollum—it’s a feature-length version of the Scouring of the Shire.

    Turing speculated that the ability to act human would be the best indication of humanlike thought, but a better indication would be the inability to act otherwise.

    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.

    What would be the drawbacks of a genetic code with 6 nucleotides instead of 4, but each amino acid could be coded with 2 base pairs instead of 3 (so the genome could be 33% shorter)?

    Is it possible to conceive of a universe macroscopically similar to ours in which matter is NOT fundamentally composed of oscillating waves, or would any such universe be logically contradictory?

    Maybe prehistoric cave paintings were actually the worst paintings of their time, because bad artists were forced to practice in caves where no one could see them.

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

    If whales are ignorant of conditions on land, they probably think humans are an endangered species.
