"Why do mirrors flip text to be right-to-left, and not top-to-bottom?"


in reply to Ben Weinstein-Raun

Honestly, the part where I see myself as being left-right switched rather than up-down switched still feels confusing to me in this frame.
in reply to Ben Weinstein-Raun

Like, if I think it through all the way, I can see why I am actually mentally privileging the vertical axis, but it's hard to get my system 1 to understand this.

Ultimately I think the biggest thing is that humans are roughly bilaterally symmetrical but not top-bottom symmetrical, and my guess is that this is sufficient to do the symmetry breaking. Like, if you parity-flip me, I still visually "make sense" as a left-right-swapped person, but I don't "make sense" as a top-bottom-swapped person; people don't have their heads on the bottom.

in reply to Ben Weinstein-Raun

So there are at least two interesting thought experiments about putative zero-g humans:

  1. What if humans were radially symmetrical? and
  2. What if humans had no visual symmetries at all?
in reply to Ben Weinstein-Raun

I think non-symmetric people in an environment that has gravity might still perceive mirrors as flipping things left-to-right. As we've established, it isn't that the mirror flips things, it's that you flip things when you turn them to face the mirror (or you imagine them having flipped when they face you in the mirror), and so the question is "what is the default way to flip things?". And I think in the presence of gravity, it's most natural to use the direction of gravity as your rotation axis, so that e.g. your mirror self's feet are still on the ground.
in reply to Ben Weinstein-Raun

Yeah, I was about to say the same thing about bilateral symmetry.

Another thing I just realized is that if I look at a mirror on a ceiling it intuitively feels like it's reflecting across the mirror and not switching left/right.



Plasma lighters are neat


Recently I was thinking a bit about updating my "bug out bag", especially thinking about including more ways to start a fire on top of just having a bic lighter. I looked around online for other fire starting tools, and learned about electric plasma arc lighters, which I had never heard of before.

Naively, it seems like a really great alternative to a traditional lighter:

  • no expendable fuel; any source of electricity can serve as fuel
  • about as easy to use as a regular lighter: slightly less hot surface area, but in exchange you get push-button activation and no difficulty positioning the flame to avoid burning yourself
  • very resistant to wind
  • iiuc, should work even in very cold temperatures where butane lighters struggle

I tentatively think these things are great. I don't know:

  • how long one full charge lasts
  • the operating life of the battery
  • whether the arc contacts wear down over time

If those considerations compare favorably with bics, I think these lighters might strictly dominate traditional lighters for a primary emergency fire source, excluding cost. Plus they look really cool.

@Ben Weinstein-Raun some combo of "our mathematical universe", fractals, string theory, and sabine hossenfelder. Basically just making fun of theoretical physics popularization.


Tired of all the little dishonesties


in reply to kip

I strongly agree with this.

Also, if you happen to be wanting to give me feedback, I highly encourage this, of course including having an anonymous feedback form (link in profile).

A thing that helps me with a million communication annoyances, at least when both people are used to using it, is the idea of generalized happy prices: to express the magnitude of a preference, just say how much money you'd be happy to pay for that preference to be satisfied, or what amount you could be paid in order to feel overall happy about the trade, even if the preference isn't satisfied. Sometimes money can actually change hands to make everyone happy; sometimes not; but at least it helps to get across preference strengths.

Paying bounties for links to AI-related evidence

not serious evidence for any of the claims but I figured you'd appreciate it. Humans are apparently very easy to use as actuators.


It's weird that candidates' use of alcohol isn't more of a campaign issue. I mean I guess it's not weird because most people drink alcohol and don't like the idea of implicitly being judged for doing so. But all else equal, it really seems like it would probably be better if the leader of the free world largely refrained from intoxication.
in reply to Daniel Filan

I feel like this probably wouldn't affect my vote in a Presidential election, but I could totally imagine it affecting who I would vote for in a primary.
in reply to Daniel Filan

I wonder if it's just a thing that Republicans are more likely to abstain. Seems so based on Presidential candidates since 2000 but that's a small sample size.


I find this first Gumby TV episode way more strangely compelling than most things I've seen from its era (1956). It's very unpolished; some frames even have visible hands in them. I wonder how they made the spacey soundtrack.

Cool ~linguistics fact (maybe this could be my brand)


This is adapted from Wikipedia.

In 2011, the Welsh author Roger Bryan discovered this poem written at the bottom of a page of saints' days within a Latin manuscript in the British Library's Harleian manuscripts. He dated the entry to 1425 ±20 years.

Thirti dayes hath Novembir
April June and Septembir.
Of xxviij is but oon
And alle the remenaunt xxx and j

Seems like they're rhyming the word 'one' with itself ('j').

Note that November is taking the place that September does in the modern rhyme. The early versions tended to favour November and as late as 1891 it was being given as the more common form of the rhyme in some parts of the United States.

The unhelpfulness of such an involved mnemonic has been mocked, as in the early-20th-century parody "Thirty days hath September / But all the rest I can't remember."

Overrated:
- Marcus Aurelius
- "Saint" Augustine of Hippo (are the haters Eastern Orthodox or atheist?)
- Cleopatra

Underrated
- Justinian I (who dislikes that guy?)
- Cicero

in reply to Daniel Filan

Cicero adapted the arguments of the chief schools of Hellenistic philosophy in Latin and created a large amount of Latin philosophical vocabulary via lexical innovation (e.g. neologisms such as evidentia, generator, humanitas, infinitio, qualitas, quantitas), almost 150 of which were the result of translating Greek philosophical terms.


In this house we respect lexical innovators (except for my irrational (?) dislike of the Lightcone Hyphen).



So the UK progress people have put out a new report about how it would be good if investment and building things were legal. And it's all good, and it makes sense that they're writing it, but I don't feel super hopeful. Maybe this is one of those things like Sonja Trauss founding SFBARF and hopefully 5 years later something comes of it?


If I got to choose one thing to change about American public schools, my first thought would be to introduce basic economic concepts as a subject with the same weight as civics.

The near-universal lack of econ understanding seems to me to underlie many of the worst aspects of current political discourse.

This stuff seems much more important for most people to understand than trigonometry or chemistry.

in reply to Ben Weinstein-Raun

I would also change this about UK state schools, for whatever that's worth


Camino Day 12


A good grade in pilgrimage is both normal to want and possible to achieve.

As planned, this was a short day. The final 15km to Santiago de Compostela are unremarkable except that you can feel the excitement of the other pilgrims.

I only spent a little time in Obradoiro Square before I was occupied with other concerns: getting breakfast, charging my phone, getting out of the encroaching rain, checking into my hostel, submitting my Credential.

I'm not a spiritual person but the past twelve days have been challenging and beautiful and intense. I've tried to reflect on how I connect with people, how I meet challenges and how I use my gifts. None of that has solidified into any great revelations; just a collection of moments.

I'm going to get a real hotel room for the rest of the trip though, as a treat.

Epilogue: ran into both of the women that I walked with earlier in the Camino in the square tonight


Of course I knew that Greenland belongs to Denmark, but TIL that there's also a small archipelago called Saint Pierre and Miquelon, that looks like it ought to be part of Canada, but is actually part of France.

Here's a pedantic remark to make my first contribution on this website: These appear to be arthropods, rather than fish. The first appears to depict a lobster or crayfish, the second and third pictures appear to depict horseshoe crabs, and the fourth picture is unrecognizable to my eye. Fish are considered to constitute all vertebrates minus the tetrapods, whereas arthropods are invertebrates, and a type of protostome.




Made an image that looks like a bunny or a bird depending on the orientation, with AI, based on this: youtube.com/watch?v=FMRi6pNAoa… It's not perfect, and there are better examples in the video, but it was fun!


Doctrine of the Mean trutherism


Doctrine of the Mean is a Confucian text. It's pretty cool IMO. Anyway Wikipedia claims that "The authorship of The Doctrine of the Mean is controversial." But I think I've figured it out, and the implications are immense.

Camino Day 10 & 11


Yesterday I woke up to the smell of smoke. There are several wildfires now I'm Northern the and the smoke has been blowing into Galicia for the past two days, creating a haze in the atmosphere. It feels awful to know that the beautiful country I just walked through is being damaged.

I continued traveling with the woman I met at the monastery. We walked from the monastery at Armenteira down along a gorgeous wild-looking river and through vineyards to Villanova de Arousa (23km). We had hoped to catch the boat that afternoon but instead we watched it pull away from the dock just as we came into view of the harbor so we checked into the municipal albergue in the local albergue.

Today we caught the boat at 1:30 and traveled up the Arousa river to Pontecesures. I left my companion at the monastery in Hebron and continued another 15km to O Faramello so that I would have less to walk tomorrow.

Everything feels more intense now that's I'm so close to finishing. Tomorrow I will walk the remaining 15km to Santiago de Compostela.

(Pictures aren't uploading, will try adding tomorrow)

Apt indeed! The writing I thought of in this vein is the 1909 short story "The Machine Stops" by E. M. Forster, which describes things like the internet.


Hello world!


Obligatory "I'm new here" post. I'll post some other things soon; posting on Facebook has been feeling aversive and it's the only social media I ever use.

Meanwhile, in what may be news to those of you who know me: I have a child now! Interested in talking to other child-havers. She's two months old. This part is honestly kind of boring - babies start out _extremely_ limited in their abilities. Her most recent milestone is that she can now somewhat consistently move her hand to her mouth. I expect it to get more interesting later. She's cute though!

I'm also interested in programming languages (I'm one of three editors of the JavaScript specification), math, language, and reasoning about the world in general. I have a draft of a long essay about reading the news I need to get around to finishing someday and if that sounds interesting to you feel free to poke me about it. I might end up using this instance for that kind of somewhat-less-polished-but-therefore-actually-existing writing.

in reply to Kevin Gibbons

I hope y'all can successfully make it up to East Bay this weekend, I am interested in meeting this small new friend of yours. (Weirdly, I had a dream the other day where I met Sage, and she was already a toddler)
in reply to kip

Also interested in reading your essay about reading the news

Still planning on trying! It'll be the longest car trip she's been on by a factor of two.


Translate things


Sometimes people are like "noooooooo I can't just translate Tian as Heaven or Dao as Way or junzi as gentleman, the terms have slightly different connotations and are used by this writer in a sort of distinct way". Nah. Writers in English use common terms idiosyncratically all the time. If you're worried we'll misunderstand, put an asterisk the first place the terms are used and refer us to a glossary. In the meantime, the reader will have a better understanding of what the terms mean.

In general I think we should translate more things so that you can understand what people are saying. E.g. "Hamas" is just short for "the Islamic Resistance Movement", call them that or the IRM if you want to save space. Most English speakers don't speak foreign languages, and it's important to be comprehensible!

in reply to Daniel Filan

I disagree...? Why not just include more foreign words in our vocab? It works pretty well, and English is already known for doing it.
in reply to renshin

In these cases I don't think they meaningfully add richness to the vocab, they're just covering space for which we already have words. Or if they are meant to mean something importantly different, I'm not getting that anyway.
in reply to Daniel Filan

i dont know words like junzi or Tian. With Dao I think we should use Dao. But shrug.

If this were about Buddhist terms I'd have more specific things to say.

But my sense of English is that it just doesn't even act like these other languages in very relevant ways. Pali/Sanskrit is super different as a language, for instance, and so you just can't translate the words into English without losing ~70% of the background meaning and connotation.

in reply to renshin

Yeah I think it depends on the topic for sure. And probably people who are specialists should use the original term. At the same time, one thing I worry about is: there's some instinct that like 70% of the meaning/connotation gets lost in translation. But do you really retain that meaning when you don't translate? Like presumably you're going to use some Pali/Sanskrit term that I won't immediately understand and tell me what it means, right? If so, couldn't you also just use an English term and tell me what it means? I think this doesn't work for terms that cross concepts in English (like 'dharma' kind of does), but does work for words that are close enough to an English equivalent.
in reply to Daniel Filan

oh i see.

yes i agree that context is important.

if you're just a casual audience, then i should use an English phrase in the conversation so you know what i'm saying at all.

in reply to Daniel Filan

So you're saying people should write more like official subs and not fan subs youtube.com/watch?v=YvNxgHTWIl…

(I have never watched a fan sub but I have observed the urge of people who are really into a hobby using obscure language because they care too much about capturing nuances)
