It's All About the 不可説不可説転円札 (or, Archive of Sino-Japanese Buddhist Hyper-Astronomical Numbers)

Despite the fact that even historically, I don't know of anyone who has read this blog other than myself, perhaps it is because of that that I have a reason to make a post after 5 years for an expected audience of one.

For context, one of the main focuses of my early education was in mathematics, and though my career has departed into the semi-related field of computer science, not much has changed about my familiarity and interest in numerical curiosities. As well as that, my university studies led me down the paths of linguistical intrigue, Japanese didacticism, and East Asian studies. So anything that is at the intersection of the Venn diagram of all four topics would certainly call my attention.

I don't know exactly when I first encountered this particular topic, but perhaps it was semi-contemporaneous with my long-ago post on Japanese ten-power numbers in relation to intuition about currency-conversion and various culturo-economic touchstones for how much 一兆円 can get you (answer: probably still a 新幹線 line but I haven't bothered doing any additional research to account for inflation or the like). But in any case, there are certainly much bigger numbers than (一兆 = 一(万万万) = (10 000)³ = 1 0000 0000 0000 = 1,000,000,000,000). For the sake of convenience going forward, I will probably adopt a neutral convention of using direct 10^x notation to avoid the need to list both thousand-scale and myriad-scale (fun fact: though used generically to refer to a large quantity and often an assortment, the term 'myriad' specifically indicates 一万 or 10⁴) versions of every large number, especially since we have a long ways to go.

Since I am not wikipedia, I won't go into the full details which, assuming that the ravages of time leave the page unscathed, ought to remain on the relevant page for long enough that future-me doesn't have to reiterate the basics.

This post will be a partial translation, partial exploration, and partial archival post for a resource that has, at some point, become inaccessible due to the impermanence of all things (which is oddly on-topic, and though there probably isn't a notion of the internet in historical Buddhism, is true especially on the internet). The resource in question was hosted at this now-dead URL: http://www.sf.airnet.ne.jp/~ts/language/largenumber.html, but which, thanks to the Internet Archive's Wayback Machine, can still be found here. Even though 100% of my known audience can read Japanese, that same 100% is a native English-speaker and so might prefer that I (viz. they) encapsulate some of the details in a more direct fashion to avoid a language barrier.

I don't know much about the original author 高杉親知 (which, based on Rikai-tan's assessment, is probably read as Chikatomo TAKASUGI), and my interest is not so much in the writer as it is in the post itself, which introduced me to a list of etymologically Buddho-centric Japanese astronomical numbers I had not previously encountered. Since my ability to read through large troves of Japanese is limited severely due to my inexposure and inexperience to such tasks, and my generally stagnant Japanese skills not having been necessarily strong enough even at their peak to read through archaic sources on esoteric topics, I won't really try to claim that I can be sure that the information I am re-presenting is authentic and unbiased, and because the names that we call any given numeral quantity are as much a social construct as most other linguistic conventions (though I do not wish to denigrate any historical significance or importance of the influential origins on words in a languge or from a culture I have no direct personal grounding in), even a misrepresentation of what sequence of characters, what reading thereof, and what etymology they derive from, ought to be relatively innocuous and uncontentious when applied solely to numbers, which are rarely ever victims (except in the case of the famous incident where nine was mercilessly eaten by seven).

Of course, even without the blog-post I am parroting, everyone probably knows by now that the Japanese counting and number-system uses explicit place-markers in the form of fixed-ten-powers as post-positional unit suffixes for any digital scalar (being 1-9, leaving 0 out). In other words, the notation for a number greater than 9 is always the concatenation of each of its significant place-values in highest-to-lowest sequence, additionally omitting the leading 一 (1*) for explicit (i.e. not the unrendered 10⁰) tens-power units up to 千=10³. Though there is no direct way of adapting this notion to the standard western conventions in using arabic numerals with purely positional implicit tens-power units, using 0 to fill in the gaps between non-consecutive tens-powers, it is somewhat close to the way that spoken English treats large numbers. "Ten thousand and four" being the way we convey the idea that is rendered orthographically as 10004, rather than reading each digit by itself in sequence like 'one zero zero zero four' (though for pure number-sequences not meant to have place-value associations, like phone-numbers and other pure digit-strings, both Japanese and English fall back on reading the numbers verbatim in sequence without attaching place-value to them, in either respective convention; with some exceptions, of course, most notably that of the emergency phone number in Japan, 110, being referred to in common speech as １１０番 (ひゃくとおばん) which literally means 'hundred-and-ten (phone) number').

I would also like to note for those who either lack the patience or ability (due either to issues relating to the Internet or the task of reading Japanese being difficult or impossible) to read the original post, that the relevant 'values' of large tens-powers are by no means a diachronic immutable, and have had different attributions either between their modern and historical usage, or between multiple 'historical' sources using the same effective kanji-sequence to denote differing tens-power-values. As with many linguistic conventions, especially those that are notational and highly abstract, how big a 'stride' one takes to get from one place-value to the next is entirely a subjective choice when taking an agreed-upon succession of ascending scale to mean a very precise thing, especially when the consequences of making a different choice than someone else are virtually nonexistant, and any choice that at least orders the symbols in the same ascending pattern in an internally consistent and logically sound fashion is basically as 'correct' as any other. So while there are multiple tables even in the one blog-post I am rehashing, with multiple columns denoting sources and the names used for the varying scales, I will try my best to show what is the 'modern accepted' version if multiple interpretations exist, and leave any further digging to whomever reads this and finds it inadequately detailed.

For those tens-power-units that are noted in 'common' usage (though their frequency is almost certainly diminishing the higher one goes up the scale, for understandable reasons), virtually all beyond 万 are effectively raised-powers of 万=10⁴ itself.

The blog post begins with the line

子供の頃、算数の教科書で大きい数の単位を知って感動した。日本語は素晴らしいと思ったが、実はこれらは全て中国から来たものだと後に知った。以下は日本語の数の表である。

Which I am, as a rank amateur, choosing to translate as:

As a child, I was moved [tr. emotionally] upon learning the large number-units in an arithmetic textbook. [At the time] I had thought 'Japanese is wonderful', but I later learned that, in fact, these were all Chinese in origin. Below is a table of Japanese numbers.

I am adapting the actual table that follows that opening line into a more compact form, leaving out the additional columns that specify the prefix-scale applied to yield intermediate ten-powers between one myriad-power and the next, and rather focusing on the myriadic powers themselves. I am assuming (perhaps incorrectly) that anyone reading this far is either familiar enough with 一十百千 to not need the additional explainer for these sub-myriad powers, or is in any case only concerned with the big numbers, not those 雑魚 (ざこ/zako). Also note that because all these powers are above 千, when they are actually being used productively to form a proper numeral quantity, a prefix of 一 would be used to denote 1*10^x.

(By 'adapting', I really mean translating/editing the original table, as an HTML entity. It's big enough that I would probably want to write a script to generate the HTML from scratch if I were going down that road, and the HTML structure itself is relatively hard to interpret as the IP of the author, since it is very formulaic and merely encapsulates existing facts rather than putting an authorial spin or creative interpretation on them. Not that I am saying 'steal from this person', I just believe that the table itself can't reasonably be designated as a creative opus and consitute what I am doing below as plagiarism. Even the adaptation of the HTML is being done by hand rather than script or, worse-yet, via AI, and is rather painstaking as-is, so I would argue that even if the original is IP, my version is a transformative product.)

^*: There are multiple notes on this particular entry. The first is that, perhaps due to font or unicode-related issues, the orignal blog-post by Takasugi-shi used a now-dead image link for this character, which I have done my best to find the corresponding Unicode glyph to replicate. The other is that there is an extended aside in the body of the blog itself, that explains that the value of 10²⁴ was originally (and properly, according to Takasugi-shi) designated by the character 「秭（し）」, which [the author alleges] was, in the mid-17th century, mistakenly rendered as the slightly-similar-looking 「𥝱（じょ）」, which has by the modern day become the de-facto tens-power-unit kanji for 10²⁴. While I can't comment on whether this explanation is historically accurate, I have no particular reason to fact-check the source that I am only attempting to preserve, not audit, and so will leave the Internet Archive link and its accompanying list of reference-links as the place to go to figure out what is really going on here. Another source linked to by the blog post in question, which can only be found in an even earlier wayback machine snapshot, corroborates this story, though it is unclear if this is the same source that Takasugi-shi is drawing on or whether this is one of multiple sources for this claim.

Now, onto the main point of interest I had in first finding this page, which, like young Takasugi-shi, I was moved upon finding.

無量大数 (muryoutaisuu, lit 'immeasurable large number), at 10⁶⁸ (or 10⁸⁸ depending on which system you are employing or what source you are treating as authoritative), is already pretty darn big, I would say. There aren't a lot of things you can reasonably count that high within practical reason, though unlike numbers such as one googol (10¹⁰⁰) which are effectively 'monolithic' large numbers without any nearby ten-powers you can ease yourself down to without referencing googol itself, it is just the last turtle in the chain of myriads-of-myriads. But it is by no means the end of the story, and we can go even deeper.

The end of the blog post has a huge ringer in the form of a list of numbers from a Buddhist source that grow unbelievably fast and which quickly outstrip the number of atoms in the observable universe and any other quantity that forms a basic upper-bound on how large a number you would ever need to worry about if you were purely a pragmatist. With the exception of the first number listed in the table that follows, 洛叉（らくしゃ） as 10⁵, the progression is based on 10^7(2x). In other words, instead of scaling by our basic myriad (which in this case, the base-case is 10⁷ rather than 10⁴ but it hardly matters by the end due to the sheer magnitude of the numbers being presented), we square each one to get the next. In comparison, if we were doing this the whole time in our basic set of numbers, 無量大数 being our base myriad multiplied by itself an additional 16 times, we would instead have our base myriad squared 16 times, or 10^4x216 = 10²¹⁸ = 10²⁶²¹⁴⁴. If you could write one zero per second without any breaks or interruptions, that would take slightly over 3 days to write down in Arabic numerals (and though it's begging the question, would take only four characters and 40 total strokes to write in Kanji if that were the actual value of 無量大数).

I might later do a deeper dive into the significance or origins of the names of the numbers given below, which for time constraints, I will merely leave as kanji with hiragana ruby annotations and not transliterate the whole list quite yet (though I might go back and edit this post later for the sake of finishing it more quickly but not leaving it an incomplete product). The majority I believe to be derived from Sanskrit terms with significance rooted in Buddhism, rendered into either Japanese Kanji or Chinese Hanzi (which I may, if I do compile a follow-up post to this one, explore further).

Without any further ado, here is the insane table, this time ripped mostly one-for-one from the revivified blog-page of Takasugi-shi (with the column-headers translated but otherwise unaltered).

I probably don't need to tell you how insane it is that, even if these numero-lexical entities themselves are even more obscure than the basically-unused 無量大数 (at least, I imagine that any usage it entertains is purely as 'the biggest number that exists' rather than the precise value of '1e68'), the fact they even existed at all, however historically, is definitely impressive.

If any of this stuff is interesting to even one person [other than myself], I'd say it was worth it to keep this list of numbers alive into a new era.

Stay tuned for the announcement of my upcoming incremental idle game where you win if your score reaches 不可説不可説転. /hj.

Ambiguity

I don't have much of an idea of what I want to post, and it has been a while, so here are some ambiguous sentences I came up with a couple of seconds ago.
こーりのかみをとけました

氷の神を溶けました

"I melted the ice-god"

コーリの髪を解けました

"I untangled Corey's hair"

きみはしたいけどわたしはしたくない

君はしたいけど、私はしたくない

"You want to do it, but I don't"

君は死体けど私は下苦無

"You are a corpse, but I am lower-kunai"

This one, I came up with a while ago (and it works surprisingly well)
きみのなわ

君の名は

"Your Name"

気味の縄

"The Rope of Sensations"

That's all for now.

裏目: Irregardless

Note: This post is in Japanese.

しばらくの休みの終わりと共に、「無関係無し」がやっと蘇りました。つまり、私はオーストラリアから帰国しました。その間、「PROGRESSI部」という英和言語交換グループに参加して、日本語の会話をしました。その会話で、日本語から英語の訳し方と、正しい英語の言い方などについて少し話しました。その結果を紹介したいと思うので、質問と答を発表しようと思います。

第一問：「しょうがない・仕方がない」
この表現は、多くの表現と同じように、英訳がたくさんあります。例えば、「It can't be helped」、「It's unavoidable」、「There's no other way」、「There's nothing you can do about it」がそのなかのいくつかだけです。でも、状況によって正しい表現が違うので、気をつけなければいけません。

第二問：成句（「おつかれさま」、「いただきます」、等）
このタイトルから少ししかわからないかもしれないけど、このグループは、ある状況で自然に言う表現を含めています。例えば、「お疲れ様」、「頂きます」、「ごちそうさまでした」、それに「お邪魔します」、「しつれいします」。最後の２つが会話に出なかったけど、同じような表現なので、述べるべきだと思いました。言った通り、英語ではそういう表現に当たる言葉がほとんどないけど、同じ状況で言える言葉はあります。例えば、「お疲れ様」→「Good job」、「ごちそうさまでした」→「That was delicious」。そう言っても、その表現を言う義務も必要も期待も習慣もないので、違う感じがします。

第三問：「遊びに行く」
これはちょっと大変でした。「今度・週末、遊びに行く？」の英語が多くあるし、場合によって当たります。英語で言おうとしたら、詳しくその「遊びに行く」という活動、行き先、予定を述べたほうがいいような気がします。別になんの予定もない場合、あるいは非特異的に言いたい場合には、「Want to hang out?」とか「Want to meet up/get together」は同じ感じがするので、正しい訳にもなれると思います。「Want to (go) play?」は、テニスなどの"play"に組み合わせる活動が文脈から察知できる以外に、ちょっと変に聞こえると思います。

第四問：お兄さん→「Elder Brother」か「Older Brother」？
両方も正しいです。でも、その言葉の感じといえば、違いがあります。お兄さんが一人しかないなら、「Older Brother」のほうが正しくなります。その一方、お兄さんだけでなく弟さんもいれば、「Elder Brother」が「弟とは別の兄弟という意味のお兄さん」という風に、区別を指すかもしれません。

第五問：「Take my shoes off」対「Take off my shoes」
英語では、「off」のような前置詞が普通に文末に出るまいという規範文法の規則があります。でも、ドイツ語の分離動詞のと違って、英語では句動詞は不思議で曖昧な文法規則があるものです。個人的な意見だけど、「I will take off my shoes」、「Let me take my shoes off」のほうが正しく見えます。つまり、「off」は普通に「shoes」の前にあるけど、その句動詞が助動詞、または 「let」のような「不定詞が目的語である」動詞のあとに現れれば、それは逆になります。

False Etymologies and Kanji: Day 1

I am excited to present my first installment of...

*drumroll*

...FE&K, also known as 無実語源と漢字 (if you want a translation, look at the title of this post ¯_(ツ)_/¯

This is going to be a semi-regular (read: whenever I think of any) feature with my legitimate mistaken etymologies and my humorous mistaken etymologies; namely, how I think a word I hear is written, or how I think a word should be written, along with the meaning that would come from that, the real writing, and the real meaning.


Let's begin:

事実ひらがな: The Word	無実書き方: False Writing	無実意味: False Meaning	事実書き方:True Writing	事実意味:True Meaning
みずから	水から	from water	自ら	(for) oneself
はなから	花から	from a flower	端から	from the beginning
てつや	鉄屋	iron store	徹夜	pulling an all-nighter
あいさつ/td>	愛殺	killing for love	あいさつ	greetings

If I think of any more, they are going to go into the next FE&K, so stay tuned. Don't touch that dial. No one knows what it does, but the last person who touched it was never seen again. In the sense that everyone else went blind.
