![Lainey Wilson - Out of Oklahoma (From Twisters: The Album) [Official Music Video]](http://i.ytimg.com/vi/1TsZH__etDA/mqdefault.jpg)
When I trade with my homies in Minecraft, we refer to 64 diamonds as a stack, so I guess we are counting in base 64?
Possibly, but that's also 1000000 in binary.
With large trades you also get things like shulker boxes being used as units
Possiblly ya
The interesting thing with minecraft is that it base ten under under 64, base 64 (a stack) for small numbers over 64 and base 1728 (a shulker) or 3456 (a double chest) for larger numbers and maybe even base 3456x1728 for huge numbers. So we have this idea of this Frankenstein number with multiple bases. For example you could in theory use the number 3,34,14,26 to mean 34 and, 3 double chests, of skulkers, 14 stacks and 26 to designate the quantity 339610. What I wonder is, can that a legitimate number? If you have to include the commas for the number to be readable in any practical manner, if the number does not follow the while base^n rule, is it really a number or is it instead a series of numbers?
Thing is that's only for those products, there's also those which stack to 16 and unstackables so it's kinda unstable, but yeah Minecraft economy is kinda base 64

True
He‘s basically giving the first few minutes of an introduction lecture to ethnomathematics, which is a relatively young but fascinating, actual field of study.
The crazy linguistics stuff is those Australian aboriginal languages that don't use relative terms for directions, they only use cardinal directions, so no "it's on the left, no on my left" which makes sense when you're a nomadic people in a country that is mainly desert and is hundreds of kilometres walk between hunting grounds. It's pretty cool, because they carry that over into English.
I don't know how new it is. I learned about this 20+ years ago in high school.
@@Diesel257 Well, if it’s old or new surely is a matter of perspective. Basically, ethnomathematics is the study of „everything about counting or calculating out of anthropology, archeology and sociology“, which means that its precursors are just as old as those disciplines, but as an actual field of study in its own right and involving mathematical analysis (rather than „mathematical laymen‘s hypotheses“ by archeologists et al), it was only introduced in the 1970s, which makes it young in comparison to other branches of the disciplines involved, let alone those disciplines themselves.

1:58 the normal reaction to Danish for a linguist, obviously
At 1. "58" lol what are the odds!
Tom’s explanation is great, but I always thought it was easier to think that you are half a dozen away from sixty.
‘Halv’ meaning half and ‘treds’ meaning sixty.
It is the same with ‘halvfjerds’ that means seventy.
‘Halv’ meaning half and ‘fjerds/firs’ meaning eighty.
@@AxelUldbjerg Dozen is 12, which funnily enough is how many inches there is in a foot.
English uses scores insted of snes for some reason.
I found something really fun that makes Danish counting seem perfectly reasonable. Skokk is 60, or three score. Øll is four score, or 80. Tylft is another word for dozen, or 12. Storhundre is 10 tylft, or dozen, meaning 120. Gross is 12 dozen, or tylft, or 144. Storgross is a dozen gross which is a dozen dozen, or 1728.
Compared to that whole mess, and there's just absolute heaps more names for different numbers used in different settings, eight and three and a half score makes complete sense, or eight and three and a half twenties
@@WlatPziupp I guess, i need the rest of the explanation. Your comparison to danish makes not sense.
I would like to give some more information on the Tongan counting system. While it is true that for brevity people mostly just say each digit of the numbers individually so that 771216 is “fitu fitu taha ua taha ono”, that would be pretty confusing since you would have to remember how many numbers were said to know the size of the number. Tongan has words for 10, 100, 1000, and 10,000 (hongofulu, teau, aafe, mano) and there are variants such as 20 and 30 being uofulu and tolungofulu, but these words for multiples of ten are too formal and are usually not used. 771216 would likely be said as fitu fitu mano tahaafe ua taha ono. (if you want to be formal you would say fitu fitu mano mā tahaafe mā uangeau mā hongofulu mā ono)
The year 2019 is always said as uaafe taha hiva rather than ua noa taha hiva, for example.
Are you Tongan?

A correction and expanding on the Danish counting:
The system of using _half_ in fractional numbers was originally quite prevalent (and can still occasionally be found), but in Modern Danish is generally restricted to 1.5, which _halvanden_ (‘half-second’). The logic behind this isn’t, as Tom says here, that you subtract a half, as much as it is that in order to have ‘half of the second’, _you need to already have all of the first_.
If you go for a run, for example, and you get tired along the way and walk the rest of the way, you might say that you ran half of the third mile, but then you slowed down and walked home. This implies that you ran the first two miles, _plus_ half of the third one. In Ye Olden Times, a Dane might well say, then, that he ran _half-third_ mile: all of the first two, and then half of the third one.
This is exactly how counting in Danish works, except instead of miles, it’s twenties; or rather, it’s _times twenty_’s. The word for fifty, _halvtreds_, is a bastardised and cut-down shorter form of what was originally _halv-tredje sinds tyve_, or ‘half-third times twenty’ (_sinds_ is an old word meaning, essentially, ‘×’, i.e., multiplication; and _tyve_ is ‘twenty’). The same is true of seventy, which is _halvfjerds_ (originally _halv-fjerde sinds tyve_), ‘half-fourth times twenty’; and ninety, which is _halvfems_ (originally _halv-femte sinds tyve_), ‘half-fifth times twenty’.
Those all involve fractional multipliers of twenty (2.5, 3.5, and 4.5), so they use this ‘half-Xth’ method. Sixty and eighty, on the other hand, involve non-fractional multipliers of twenty (3 and 4), and they therefore have no need of the ‘half-Xth’ method-they are simply _tre sinds tyve_ ‘three times twenty’ and _fire sinds tyve_ ‘four times twenty’. (It has been joked that, to continue the trend, the Danish word for a hundred ought to be _fems_, but it’s not, because that would just be odd.)
Or at least, that’s what they all *were*, a long time ago. Some syllables have been chopped off since then-quite understandable, really, given that ‘78’, for instance, would have been _otte og halv-fjerde sinds tyve_ (‘eight and half-fourth times twenty’), which is quite long.
First, the final _‑e_ in all the ordinal numbers (_tredje_, _fjerde_, _femte_) got kicked out (in the case of _femte_, the t got booted along with it). Around this stage, people sort of stopped thinking about the maths behind it and just perceived it all as words for numbers, and they started treating them as single words, rather than phrases-writing them as single words, and pronouncing them with only one stressed syllable. That left us with _halvtredsindstyve_, _tresindstyve_, _halvfjerdsindstyve_, _firsindstyve_, and _halvfemsindstyve_.
Eventually, people realised that-since Danish puts the ‘ones’ (i.e., the numbers under ten) first and multiples of ten are always last-every single number that ends with a number in the 50-99 range was pretty annoyingly long and also ended in _‑sindstyve_. Kind of pointless to have half your numbers end in the same three syllables-that’s just useless crud. So those three syllables gradually got shaved off at the end, too. The only thing that was eventually left behind is the initial s in _sinds_: we now have _halvtreds_, _tres_, _halvfjerds_, _firs_, and _halvfems_, which one might semi-seriously transpose as ‘halfthirdt’, ‘threet’, ‘halffourtht’, ‘fourt’, and ‘halffiftht’. This is of course much simpler and much quicker to say, and you also don’t have to worry about the maths behind it-just learn the words. Most Danes, indeed, are quite unaware of this complex history behind the numbers they use every day.
Ordinal numbers are still a bit of a problem, though. Danish is less consistent in how it creates ordinal numbers than English, which uses _‑th_ for all ordinal numbers above three:
- one to three have their own quirky ones and are irregular;
- four uses _‑de_ and a different root vowel; and the d in _‑de_ is not pronounced anymore
- zero, five, six, eleven, twelve, thirty, and million (plus milliard, billion, billiard, etc.) use _‑te_, though six is quite irregular, too: _seks_ → _sjette_
- hundred and thousand are the same as their cardinal numbers (_hundrede_ and _tusinde_), although the cardinal numbers frequently drop the final _‑e_ in the singular
- seven, eight, nine, ten, and thirteen to twenty use _‑(e)nde_
Back when all the 50-99 words ended in _‑tyve_ ‘twenty’, the ordinals naturally ended in _‑tyvende_, because that’s the ordinal for twenty. In more formal and traditional language (and even in normal, everyday language to some people), they still do. To me, for instance, the ordinal number to go with _halvfjerds_ is _halvfjerdsindstyvende_. That appears ridiculously irregular on the surface, though, and many Danes have come up with simplified ordinals, using the apparently impressionally most common and ‘regular’ ending _‑ende_: _halvtreds_ → _halvtredsende_, etc. I expect in time, these will win out, but to me, they just sound bizarrely wrong, like saying ‘oneth’, ‘twoth’, and ‘threeth’ in English instead of ‘first’, ‘second’, and ‘third’.
Congratulations, by the way, if you managed to read all this. You now know more about Danish numbers than you ever cared to. ;-)
kokoshneta Ooh thanks for explaining all of that! :D Also the half-second thing reminded me that that's how it works in Finnish too... at least for 1.5. I imagine it was probably so for higher ones too back in the day. And the old way of counting beyond ten here worked a bit like that too. 11 is yksitoista ("one-of-second" roughly) short for yksitoistakymmentä ("one-of-the-second-ten"). For 11-19 that system is still in use but it used to work for any number between 10 and 100 at least. Yksikolmatta ("one-of-third) = 21, kaksikolmatta ("two-of-third") = 22... and so on. It fell out of use though.
Tuuliska
Interesting! I had always just assumed that _puolitoista_ was a loan from Swedish (before they got rid of that construction themselves). Never knew there used to be an _yksikolmatta_ as well!
It might still be a loan? Tbh I don't know where the system came from.
_Puolitoista_ could possibly still be a loan, but _yksi[kaksi…]kolmatta_ and even _yksi[…]toista_ can’t, because that never existed in Scandinavian.
This is superb, explaining not only how the number system works, but how (and why) it came to be the way it is, and how it continues to change. Thank you!

That's not the part Tom was complaining about xD
you lost me at "half thrice times 20"
A lot of us Danes would find it just as weird as you do. To us, “halvtreds” is just a word that means 50. We don’t contemplate its etymology every time we use it.
I'm not Danish, but I speak German (similar enough). So half thrice means a half befor three. Like in German we dont say half past six or slmething. We say half (to) six with the "to" bekng omitted for simplicity.
A more accurate translation would be "half third", as in "half of the third one". But in order to have half of the third one, you must already have the first one and the second one. So you have two wholes and one half. That's why "half third" means 2.5.
And obviously, 2.5 times 20 equals 50.
Same
@@hopseshopsidis Yea, I'm Norwegian and we do the same with time (hour of the day). We say "halv tre" for half past two. That's our shared germanic heritage. The Swedes don't though, they get as confused by "halv tre" as I get by "halvtreds". (Edit: Apparently they don't get confused, see two comments below.)
I'm an anthropologist, so I really REALLY appreciate this linguistic content on this channel. Just so you know, not only Papua New Guinea (which is really the holy grail when it comes to linguistic and cultural isolates) but also Amazonia has some interesting counting and number systems. They also use the body count system where you go around your body. There is a graduate student doing his thesis on this subject of counting systems in Amazonia at the London School of Economics!

Speaking of fiction: the elves in LotR and Tolkien's other fiction use base six and twelve. The word "Menegroth" (an important city/palace in the Silmarillion) is translated as "Thousand Caves", but probably means (12 times 12 times 12) "1728 Caves" (or, more likely, the word just means a generic very large number to get the point across that it's a big underground palace/city).
Well, Tolkien was a linguist.
I came here to say just that
base 12 was already used by humans, just look at your clock :)
Just goes to show that Tolkein was a Linguist first and foremost.
Yup, and that's why it's so rare in fiction. Because Tolkien was a linguist and most authors aren't (or aren't dedicated enough to do a whole new language for every universe they create).

@ Star Trek, one of the old pc games they had a Mission involving two ancient races with different numeric systems, base 3 and base 4 and you had to solve a riddle involving 'translating' information between the systems.

And it was base 2 and 3
I remember that puzzle being my first introduction to different bases. I was in elementary school at the time so it was years before I encountered it in math classes.
Some of the Cyan games involved base puzzles as well. Riven used a child's game (involving prisoners being fed to a whale shark, which says its own story about the setting) and other clues in a classroom to teach their base 5/25 system and later used it in other puzzles. Obduction used a base 4 system that was relatively simple once you got it but it was displayed graphically on machines that had autocorrect and an odd layout, so if you started down the wrong path figuring it out it was easy to get lost.
I remember when my brother and I played Riven we got to that part and then went what we thought was far beyond what they required, just being math nerds and seeing what we could figure out with the number logic. Puzzles in the moment were just "can you count to 5" so the rest was superfluous world building. Until the very end of the game, when a code is written in the more complex system we'd figured out already.

I would argue the one making the silly points around the words knows very little about cultural linguistics.
I'm not Danish. I understand some Danish sure, but I've never heard these. Nonetheless it's obvious these words have implicit meanings that are intuitively understood by the culture expressing them, and that they are not literal instructions for math as seemingly suggested.
It's clear these words have far more to do with linguistic style rather than numbering or numerals. It's a shame to see a mathematician treating them with such literal meaning.

I like this new guy!
TheFifaHawk And he's actually mentioned on his facebook page of the video that this'll be his last numberphile video, since as he said, is a linguist. But check out his youtube channel! He's got heaps of videos on a wide range of topics and they're all pretty great!
Yeah Okeay

Derek Schwalenberg SuperbowlL does look funny though!
I have a friend from Norway and when he visited I said I would meet him at 'half 3' - he turned up at 14:30 i.e half of 3 o'clock. I turned up at 15:30 - he was a bit grumpy.
Half OF three would be half past 1. You mean half TO three. Which is also how they do it in Germany, if I remember from school correctly.
PiousMoltar Yes Germans use half to the hour where we use half past the hour. Safer to use 3:30 or even 15:30
@@PiousMoltar Chris never said 'half of three', he said 'half three'. As Tom explained in the video, 'half-X' in Danish means 'X minus 0.5', not 'X times 0.5'. I assume Chris is saying that the same is true of Norwegian (which is nice to know, if hardly surprising).
Catalan has a similar thing with time - it gets to one o'clock, then it's one quarter of two (un quart de dos), two quarters of two, three quarters of two, two. And, yes, in German 'half three' (3:30) would be 'halb vier' (= 'half four')
Also Afrikaans (South Africa): "half drie" directly translates to "half three" in English, but means half past two. Imagine the confusion for our poor schoolkids, for whom English and Afrikaans are the two major official languages (of 11 total), and for most of them neither is their home language.
Så fint!
I have been a numberphile subscriber for over 6 years this is the most intriguing video I've ever seen. Word people doing numbers is amazing. I love this. Thank you.
I've just gone full circle. I was watching Tom Scott's channel. Something interesting popped up in the suggestions, from The Map Men. This led me to a Numberphile video. And that led me back to Tom Scott.
What you have done there sir, is called “falling down the RUclips rabbit hole” 😅
So happy to see Tom Scott!!
Samyak us too!
There are some videos on RUclips I just can't stop watching over and over.
And Tom Scott is in most of them.
Awesome video. Love the energy and the genuinity that is transmitted, also how the admiration for the things you explain come across... If that makes sense.... :)
Me: _sees Tom Scott in the thumbnail_
Also me: :O
-hey dude
-what?
-58
-w-wait, did you said 58? It c-can't be... I'm... I'M SO CONFUSED GAAAAH!!!
oh ok
WTF, I thought you were the programmer/encryption guy. Stop switching majors on me!
Computer has it's own languages. Java, C, Python and all those are computer languages. And they count in base 2, with 0 and 1.
+GotEide not necessarily, even though computers do stuff in base 2, you never type 1s and 0s when coding. Programming languages are more or less lots of words and brackets xD
+j0h00 Gotta check your assembly buddy xD Not that many words and brackets, and a considerable amount of 1s and 0s.
I think most assemblers support hexadecimal, decimal and binary, but disassemblers usually show hexadecimal.
there are 58 likes ahhhhhhhhh!!!!!!!
I developed my own way of counting on my hands. Right fingers are 1, right thumb is 5. Left fingers/thumb are 10/50. So I can count up to 99 on two hands. I've been doing it that way for years, and it's just second nature/muscle memory for me now.
haven't thought of that as well
"The truth, as always, will be far stranger" - Arthur C Clarke
You can also count with your fingers in base two- it's hillariously confusing to people who don't know what you are doing.
Wyrd80 1023 potential numbers! Or 1048575 if you use your toes
4 can be a little problematic in North America, or 2 if you counting a byte.
P.S. Base 16 is the superior counting system.
Binary is base 2. Using binary code with your fingers will probably make people think you have some sort of mental condition lol.
saying 4 in binary with your fingers can really insult someone :D
I showed a friend to count in binary starting with index and ending with thumb so 2 is the bird and now as an inside joke we say 2 as an insult and people get really confused.
the "og" in otteoghalvtreds means "and"
Yeah he said that.
Tryo The Pyro he did not. he said it was just to link it together and to ignore it. so i just explained what it meant
what he sayd was he thinked the o in og was part of the word for 8 and the g linked it together

Great video content but forget that, this is possibly Tom's best ever performance
I’m learning Japanese and came across this quite a lot! They use a combination of Arabic numerals and their own script (same as China) and their hand symbols are sometimes different too, a closed hand represents 5 and an open one represents zero, so you count how many fingers are DOWN rather than up (however this is purely for counting, not to show one particular number)
Also similar to comma separators, they have a word for 10 thousand so instead of saying million you say hundred ten thousand so some maths is required to just translate the words for numbers.
In Greenland we have a very wierd counting system: ataaseq (one), marluk (two), pingasut (three), sisamat (four), tallimat (five), arfinillit (six), arfineq-marluk (second six), arfineq-pingasut (third six), arfineq-sisamat (fourth six), qulit (ten), aqqanillit (eleven), aqqaneq-marluk (second eleven), aqqaneq-pingasut (third eleven), aqqaneq-sisamat (fourth eleven), aqqaneq-tallimat (fifth eleven), arfersanillit (sixteen), arfersaneq-marluk (second sixteen), arfersaneq-pingasut (third sixteen), arfersaneq-sisamat (fourth sixteen), inuk naallugu (twenty, which literaly means 'the whole body' (fingers and toes)). I think it is in base 5, idk.
Seems like they wanted it to be base 5 but couldn't stop using base 10.
Really, what a weird system.
Yes, this system seems to be essentially base five. Also, you seem to think the numbers six, eleven and sixteen are very significant since you use them to form other numbers. That jibes with using "the whole body" as the word for 20, since when finger counting six is the number when you move to your other hand and sixteen is when you move to your other foot. Eleven is when you jump from your hands to your feet. Base five system with origins in finger-counting. Fairly normal on the whole, actually.
Sophie Jones The six feels like the “infinity” in children’s play for who can think of a bigger number: A: “infinity”, B: “infinity plus 1”... A: “omega”, B: “omega plus 1”...
I can't like this video enough
Oskar Kylvåg well hope you share it around then!
Numberphile will do!
+Oskar Kylvåg In danish that would mean you don't like it. ''I can't like it'' = ''I don't like it''
That doesn't surprise me. The scandinavian languages *are* pretty similar. :)
+Bison Ware No it wouldn't. "I can't like this enough" = "Jeg kan ikke lide dette nok". The "enough" = "nok" at the end makes the difference in both English and Danish. Just realized this is an old comment; I don't care.
Great video, thanks for putting it together. It was my understanding that Klingon was base 3 until they met other species. They switch to base 10 to keep interactions easy. I think I got that from a Michael Okuda book
I think it is mentioned in The Klingon Dictionary, it was basically One, Two, Three, more than three (I even think Three and More than three were the same word)
6:07 As someone who grew up there, absolute not. The lakh-crore system gets really annoying, especially at higher numbers
"Keep Calm and Kling On"
Glorious.
Congratulations, you've got all the hand gestures from 1 to 10 correctly!
Yes, but only in certain part of China. In Hong Kong, the hand gesture for 1 to 10 is not the same as in the video, in particular, 7 and 8 are different.
Thanks, @Numberphile. Big fan of @Tom Scott.
I'm from South Asia and grew up with the Lakh-Crore system. In school I thought we used to put two digits in each group in the past, but made the last group three digits long because of the British influence from colonial times. But then I learned it had actually been like that long before the Brits came along.
In Japan, they have a word for ten thousand, which means that one million is spoken as 100 ten thousands.
Mandarin does the same thing I believe
Same with Chinese.
It's because they use groups of 10^4, rather than 10^3, so there are unique words for 10, 100, 1000, 10000 and then it wraps to 10 * 10^4, 100 * 10^4, 1000 * 10^4 then a new word for 10^8.
So that's why the Japanese version of the Pokémon move Thunderbolt is 10,000 volts.
***** In the original Japanese Ash actually says 100,000 volts (十万ボルト), I guess they thought 10,000 sounded better in English.
I enjoyed this video way more than I should have...
Because of the linguistics or because of the math? 😂
I'm not sure... I was expecting to get mind melted because of either... but pleasantly, was not.
Thank you random video popup at 2AM the morning, I am NOW FULLY awake after this amazing and thought provoking video.
Thanks for sharing. I just found your videos and have enjoyed many of them since yesterday.
Oh yeah, Danish numbers, the second biggest _"why haven't they changed yet to something more sane yet"_ I encountered while learning Danish.
The biggest is that spoken language is nowhere near the written language.
Leo Wattenberg In Norway we (well, they, since I wasn't born yet) switched from saying numbers like 21 as "en-og-tyve" or "en-og-tjue" to saying "tjue-en" in 1951. The decision was mostly made to reduce errors in phone numbers, but it has made the number system much more coherent. (Mainly getting rid of the "unit in the middle" problem with the hundreds, because a sensible number system need to have the digits spoken in strict ascending or descending order of significance.)
My friends and I often joke that Dansk Sprognævn must be permanently drunk because the way they have decided Danish should be spelled is so inconsistently that we've managed to make it harder to learn than Mandarin Chinese for foreign speakers, and we spend 10 years educating our children in spelling and even then we have a hard time getting it right.
How did we manage this with Latin characters? Mind blowing.
IshayuG By creating three more, that's how. x)
Nillie Which language? Bokmål or Nynorsk, or both?
Leo Wattenberg Both, though "tyve" was mostly bokmål/riksmål from what I understand.
I thought he might also mention how the British used to use the long scale billion (10^12) while America uses the short scale billion (10^9), which is now normal usage in both countries.
MrID36 That's already been discussed in another Numberphile video.
Nillie Thanks. It's possible that I've seen it, but it didn't come to mind while I was commenting.
MrID36 How big is a billion? if u wanna see ;)
I still use long scale outside of official things. It just seems more natural, a thousand thousand is a million so a million million is a billion.
Well, in German it goes from million to milliarde to billion. And from there to billiarde to trillion to trilliarde. See the problem when translating large numbers to English?
The thousands separator often confused me because where I'm from, we simply do not use any thousands separator. Sure in textbooks the groups of three will maybe be slightly separated by a little space, but that isn't universal. And when writing by hand or typing on a computer, we leave no spaces, we put no separators, one million is simply 1000000 and that's it. So in fact, not even the very existence of the separators are universal, some don't use any :)
Edit: grammar :P
Tom Scott meets Numberphile. Best crossover in years!
8:27 "keep calm and kling on" 😂
In switzerland soixante-dix is septante,
quatre-vingt-dix is nonante and in some areas of switzerland (not all) there's even a huitante which is quatre-vingt
Septante comes from old french setante.
Huitante comes from old french uitante.
Nonante comes from old french nonante. The spelling of this number hasn't changed.
Damn, never thought of it that way, I think I'm gonna start confusing my French friends by using these...
Again, same in Belgium
And what exactly is a septante, a nonante and whatever that other one was?
@@RajA-jw7dd can you confirm this? I'm Canadian and we never learned about this in French class, but then again it's sort of a more general take on French(often times we learn the same word used in France and Québec)
@@THEPELADOMASTER septante = 70
octante = 80
nonante = 90
One of the most mind blowing videos I have seen since ages.
This is fascinating. I think this is my favorite numberphile video
I count my fingers in binary. Since I have 10 fingers with two possible states (down and up), I can count to 1023 on both hands. You could say it's pretty... handy.
Note: I can count to 31 on one hand. Just so you don't have to do the math.
I consider the states 'down' and 'up' as 0 and 1 respectively, the first finger is 1, the second is 2, third is 4, fourth is 8, etc., and you just have to add up the values.
You can get up to 4 bits per finger (maybe more?) if you fold them in weird ways
*****
I've managed three definite positions with my fingers: Fully down, bent, and up. The rest seems like it would have the same problem as actual electronics where it would be hard to define the difference between, for example, 3 and 4 in base 10. It would also probably be hard to accomplish without external support (For example your other hand, reducing the fingers you can use by 5 and therefore nullifying the additional numbers achieved by the positions.)
Based on that my son came up with the notion that "4" is an obscene number when he was about 13...
So if you use your toes, you can count to 1048575

Theoretically.
That was a wonderful blend between language and numbers.... nice... this guy is kinda funny
His channel is great, you should check it out. Tom Scott.

Of all Numberphile videos, this was one of the most interesting for me.
Yeah man, love Tom Scott. Even after all these years, his style is on point.
Base 12 is easily counted on one hand using the thumb to count the joints of the remaining four fingers.
They have that in the base 12 video.
also you can use your other hand to talley dussins
you can count binary if you say finger stretched out = 1 and finger tucked in = 0
I know this comment is a year late but in Vietnam we do count this way. Not so much for the young people but my parent generation does this still. This is how my mum counts.
Use the base of the fingers as well and you get base 16
Watch the words:
English:
Million: 1,000,000
Billion: 1,000,000,000
Trillion: 1,000,000,000,000
Quadrillion: 1,000,000,000,000,000
German:
Millionen: 1.000.000
Milliarden: 1.000.000.000
Billionen: 1.000.000.000.000
Billiarden: 1.000.000.000.000.000
...and only THEN comes the german trillion (Trillionen).
We also use quad and quint but way later because we have 2 "stages" for each of them.
Except you forgot billion so they're all off. Would be nice actually if they did line up and billion was used for 1,000,000.
French also does the million milliard thing. I believe the UK did/does as well.
+Kyle Kafka Woops, human error at its best. Corrected it.
But hey, you messed up too! ;)
1,000,000 isn't billion. It's million.
+TKay no I was saying that it would be nice if we got rid of million and started with billion in its place. That way there's two groups of 000's in 1,000,000 and bi means two. And then trillion (tri means 3) would be 1,000,000,000.
Kyle Kafka Gotcha. Yeah that would be logical but...it developed that way for a reason.
Now don't ask me what the reason is. ;)
BigBen Hebdomadarius ( his :) ) Thanks, will do. Do you really think it's complicated?
Great Scott! Tom's on numberphile.
This is definitely not as complicated as the number systems mentioned here, but I find it fascinating that Filipinos--or at least, Tagalogs--rarely use Tagalog words for numbers. We might when talking about things fewer than ten, but more than that, we often switch to either English or Spanish. We use English in casual conversation, but when talking about money, or time, we often use Spanish until we reach a hundred. At a hundred or more, we often use English.
YES TOM SCOTT
Ily man you're awesome
I can grasp only lakh and crore. even when I read million and Billion, I convert in my mind to get the scale of the number
The cool thing is, they all derive from Indo European.
dekm > Sanskrit daśa, Greek deka, Latin decem
kmtom > Sanskrit śatam, Greek (he)katon, Latin centum
(sm)gheslom > Sanskrit sahasra, Greek khilioi, Latin mille
Indo Europeans could apparently count up to a 9999. In India, the system was expanded with laksha, koti etc., in Greek with myrias (10,000) and in modern Europe with million etc. (from Latin mille). But they all originate in the same system.
Same here, it just flows naturally from ten thousands to lakh to ten lakhs to crore. It feels like an extension of the metric system, while million and billion feel like completely arbitrary numbers.
@@aoarashi3025 Yeah I have always been wondering that, why is it thousand? why not ten hundred. then I learned that Americans actually do that, only to learn that they then go from ten hundred to ten thousand, which makes absolutely no sense (but then imperial system, what'd you expect)
But then lakh is just as weird, because it's not 10000.
@@patrickkeller2193 yeah, the ten hundred - ten thousand switch in American English is a bit confusing sometimes. It seems sensible to me to have a different term for 10^4, rather than ten thousand or hypothetically hundred hundred, but that doesn't seem to be a thing.
Ten hundred is mostly a verbal thing here, I think. When I see 1200, I think "one thousand, two hundred," but I _say_ "twelve hundred." It's shorter and flows easier. Once you hit 2000, it goes back to thousands - people won't say "twenty hundred".
It is the first video I found on numberphile as much as I watched it that signifies/talks about the concepts from India and Southeast Asia .... And I'm really proud to use the number notation system we use in hindi (because I'm really used to it )... Though I like the sanskrit counting much because it feels a lot easier than hindi as you don't have to learn that much about it...
P.S. correct me if I'm wrong at any point ...
"We have weirder systems that sscience fiction has ever come up with"
There is a series of video games, that shaped pretty much the whole genre of puzzle games, called Myst
In it there is a language called the D'ni that comes from a people of the same name, and I think they're fascinating
Where Klingon is basically a 1 to 1 from english, D'ni has just nothing to do with it on every scale
On the langage side, words aren't just 1 to 1, there is a totally different grammar and syntax system
and the alphabet is actually phonetic with 35 different symbols that are a combination of 13 unique line paterns
But most interesting of all is their number system that is what I'd call a double base 5
There are 25 symbols that you would use as a standard base 25, which in itself is already pretty unique
But the 25 symbols themselves are constructed on a base 5 system :
There are 5 base symbols from 0 to 4, and (excluding 0) if you rotate them by 90°, it's like multiplying them by 5
and if you take that multiple of 5 and superimpose it with the symbols from 1 to 4, it acts as an adition
So to write 87, you first get 3 * 25 + 12, the first symbol is 3 in 25's place, and the second in the 1's place is 12, written as 2 * 5 + 2
This is hillarious to watch as a dane :D
And yes while we mock the US for their imperial outdated measuring, we silently ignore our horrible number system
Yep. In Denmark it got to the point where our banks went "screw this shit!" and decided to change the number system - so they will say femti instead of halvtreds, because it consists of fem and ti, literally five-ten, so 58 would then be femtiotte, which makes a ton more sense. The Swedes already use this in every day speech as well.
We also have halvfjerds, which is 70 and halvfems, which is 90. Same idea as with 50.
And let's not forget we of course swap around the two rightmost digits in the number, and we use the long system (so we have milliards and billiards and so on)
It is so funny.
i have a set of jokes for it (norwegian here).
tres = 60.
Now divide that by 2, and you get half a tres which is 50.
firs = 80.
divide by 2 and now you have hald a firs which is 70.
I know it really isn't like that as Tom scott explained, but i cant stop laughing at this!
oaaserud By the same logic, two "halvannenlitersflasker" (common Norwegian phrase that literally means "half-second-litre bottles", i.e. bottles of volume 1.5l) should have a total volume of two litres. It may not be *quite* as strange as Danish, but please don't pretend Norwegian is a particularly logical language- it's a nice language, sure, but not a logical one.
The half-to-the-next terminology doesn't stop there, though: a similar terminology is used in a wide variety of languages when talking about time. For instance, in English, "half-five" in reference to the time of day means half and hour past the five hour mark in that particular 12- or 24- hour cycle, i.e. 5:30; not halfway between the starting point of said cycle and five o' clock. By contrast, a near identical phrase exists in Norwegian, but there "halv fem" would mean halfway to five o' clock from the last hour before that, i.e. 4:30. Sure, there is a logic behind both phrases, but both are based on widely understood subtext and only really logical in terms of modular arithmetic.
John Smith almost the same, "halvannen" is short for half and another pretty much. one half, and then a whole.
Norwegian is stolen from the danish language, and danish from german/english i believe?
I'm not saying every other language on the planet is genius and perfect.
I merely said that i find the danish counting system particulary funny :-)
I wouldn't say that Danish (or other complex numbering systems) are horrible; they're simply made under linguistic pretenses instead of molded to ease of context.
I'm not saying this is the answer, but sometimes a language is made complex in order to dissuade foreigners from learning the intricacies so a native can note a difference between a local and a foreigner. Could be for war purposes (to make it harder to decipher) or simply to create a form of elitism.
I grew up learning English, took classes in high school to learn a fair amount of Spanish, and dabbled in Japanese in college...after looking at Dutch, I laughed and said, "no thanks."
I'm seriously shaking my head at "Keep Calm and Kling On."
a language-based twist on numbers that focuses on how amazingly different perspectives can be all over. This was the best.
Great combination to see Tom Scott on Numberphile
58 in Danish: otteoghalvtreds - eight*and*half-third
68 - otteogtreds
78 - otteoghalvfjerds (half-fourth)
88 - otteogfirs
98 - otteoghalvfems (half-fifth)
+Kim Philipp Möllgaard jeg hater maydayer, det verste jeg vet er maydayer!
I'm danish, and must admit that I still get confused by the reverse order of the digits once in a while. Like, the number 1234 is "ettusindetohundredefireogtredive" which is essentially like saying "one thousand two hundred four and thirty". The germans and dutch do this too.
Fun fact: Chinese and japanese people don't use a 1000 separator but rather a 10000 separator, so you'll see very large numbers written as "123 0000 0000 0000".
Det er ikke helt rigtigt, 60 staves uden 'd' (altså 'tres' i stedet for 'treds' som man gør i 'halvtreds), da det jo blot er tre snes, mens halvtreds er halv tredje snes.
Thanks. I don't know why I keep forgetting that.
Danish spelling is generally a nightmare.
And another comment of correction as well: The second 'o' isnt part of the 'eight' but with the g spelling the danish word 'og' which means 'and'. So it becomes 'eight-and-half....'.
The 'Chinese hand gestures' can vary quite a bit depending where you go and who you ask (btw he did them quite well). I believe those originated from accountants and merchants who didn't want competitors overhearing their conversation, so naturally there was no nation wide standards.
This is one of my favorite videos on RUclips. I am compelled to observe that if you count by the phalanges (the bones of your fingers), you can count to 12 on the fingers of one hand, using the thumb to mark your place. This would also mean that it's much easier to represent thirds and sixths in your number system without repeating duodecimals past the duodecimal point, although fifths become problematic.
Mind blowing, dude! TFS.✨👍🏾
