Except geometric means the exponent is fixed, i.e.

f(x) = x^2

f(x) = x^3

...

f(x) = x^n

where n is a constant, while exponential means the exponent is the variable, like

f(x) = 3^x

Conversely, I do amphetamines (legally, prescription) and still occasionally drink. At the height of my drinking I'd have 3 drinks in a night (usually more like 1-2), maybe 4-5 nights a week, but the rule has always been that I would only drink if I felt safe to do so, had something else to do (while drinking), and most importantly, am not in any negative mood or depressed. These days I only really drink for celebrations, and looking around there isn't much left to celebrate. I still drink occasionally, but it's been down to like 1 drink every other week, with company (and only mead, my body can't handle beer or even wine anymore).

Not the same person, but to me there's a different feel to the lingering fingerprint of a recent working memory and the memory of longer-term storage. It's enough to matter.

I think that's why this sort of phrase never made much sense to me, because in the same sense that the broken clock is right, a working clock with an offset (technically all of them) is almost never right (as you mention). Maybe it extends the metaphor, though, because while the working clock is never completely accurate, it's much more useful by being closer to the truth the vast majority of the time.

And fewer moving parts means less expensive maintenance, generally. Granted, replacing a battery can get expensive, but if you're not going all that far anyway, the battery's range dropping from 400km to 200km after 12 years or so might not be a big deal. That said, the boots theory of socioeconomic unfairness might mean you're stuck with ICE vehicles for a while if you can't get a loan for a comparable amount of time.

Edit: after looking it up, that's also assuming a worst case loss, average range is now roughly 460km, getting better, and it's still at ~78% capacity 10 years later.

And the fruit's name is different from other countries' names for it because "a naranj" was misheard as "an orange" and it stuck. Yellow-red wasn't much adopted, though it did exist. Such is language, what a fun collective hallucination.

An EMP could be thought of as a big powerful radio wave, right? Could someone create something like a radio laser to direct a pulse towards a target?

You're probably old-ish (late 30s to early 50s maybe?), and you're absolutely still ok (in this way at least, maybe not your joints or gut though).

It absolutely starts before that (as possibly the most heritable disorder), but parenting can definitely exacerbate the disorder. For more context, the set of genes responsible for ADHD are those responsible for producing various collagens (there are many types, they all do something slightly different, but there's enough overlap that losing one or two will still allow a viable embryo). Collagen does a lot in the body (like holding ligaments to bones, which is why there's such overlap between hypermobility disorders and ADHD), but one of the main things it affects is the interstitium. The interstitium is the recently classified organ responsible for channeling and distributing the various signaling/growth/immune system molecules throughout the body. When a collagen missense gene fails to create or changes the shape of a collagen subtype, the shape of the interstitium's grooves and its distribution changes throughout the body; in development, that changes how the brain grows, and what it has access to in its regions (usually leading to deficits in the prefrontal cortex). ADHD and autism are absolutely baked in from the start and impossible to reverse.

I think it's because we've "solved boredom". Sometimes with heavy, hectic, stressful events that come one after the other, sometimes with passive media, or algorithmically generated media, or doomscrolling: shows, clips, or posts designed to engage or entertain, other times with little clicker, distraction-style games; all of it seems to just drain every last drop of dopamine anyone can muster until there's no room for anyone to have volition of their own. It tends to put a damper on the amount of time and energy one has for more longer meaningful interactions, and you end up almost, but not quite, completely content to microdose human interaction with single-serving friends by making comments on posts like this one (or the various parasocial interactions with internet micro-celebrities, or much worse, hallucinating a meaningful conversation with a statistically probable paragraph generator like the ones in the post).

And new neurons are being made all the time, just more slowly and in specific places that then migrate to where they're needed, so as not to disrupt too much of the neural mesh (and thus completely derail memories or other models).

on Paul Erdős · c/wikipedia · 6 pts · 62d

I tend to be a bit tongue in cheek, but for more background he started in the 1970s, only a few years after stimulants were researched for ADHD treatment in children. He undoubtedly had connections in that area (the Erdós number is a thing, after all), and in the prior 30 years was known for drinking copious amounts of coffee, so better stimulants weren't exactly a difficult jump to make regardless, but it wasn't necessarily that he knew he had the condition now known as ADHD, just that they were what worked best for him.

on Paul Erdős · c/wikipedia · 11 pts · 62d

Ah, so he likely had ADHD and self-medicated with the substance that just happened to be the most effective treatment for it, allowing him to actually be productive. And he "solved" the other issues of ADHD by trading his services for room and board at colleagues' living spaces.

If you consider Przewalski's horse as being closer to the original lineage than what we've bred them to be, I'd imagine they didn't have as many issues, in the same way Przewalski's horse doesn't. They're smaller but stockier, so they can hold themselves up on three limbs, their skin isn't as tight so it can heal from wounds better, and their soles are thicker so they can run on rough terrain without as much risk of injury. We bred horses to work, to carry us, and to be shiny, and I think that ruined much of their resilience.
