Debate on... Math and Computer Science [Home Thread]

Thanks for sharing the eBook link. I created a thread for the book club reading sessions: パソコンの秘密 (Math and CS book club) and added both links in the intro post.

My suggestion would be ~one chapter per week which would make it seven weeks in total to go through the book. To balance it out with some math topics we can read it bi-weekly as well. How do others think about it?

I think weekly would be better in my opinion, seven weeks is a decent time span I think.

I also think doing some advertising in the Beginner Book Club for this reading might be good, since the book seems to be on a decent level for beginners. That way we might get some more people to join us who maybe aren’t checking this thread.

I’ll be pretty busy for the next four weeks, so I might sit this one out. I’ll try to drop by from time to time in the reading thread though.

Would this thread be interested in learning some more basic concepts? Here is a site that explains elementary and middle school subjects (and a bit of math 1 for high school) made for native Japanese school kids. I’ve watched one video on their elementary school 5th grade math section just to check it out and it seems really easy to understand.


That looks easier to navigate than NHK for School just based on the layout. Thanks for the link!


Thanks for sharing your opinion. I’m happy to go with the one way or the other.

Thanks for suggesting it. Yes, beginner level seems to be suitable. I’ll check in with @Micki senpai and maybe tag a few more durtles who (I think) are interested in CS related topics. → In case you or others have ideas about advertising feel free to go for them :slight_smile:

Thanks for sharing. No worries at all, please take your time.

Thanks for sharing the link. As they have other topics, like kokugo or shakai studies as well, this resource might be interesting to advertise in the The Ultimate Additional Japanese Resources List! thread as well :slight_smile: @Kraits senpai: how do you feel?

Oh yes, I was just looking at this the other day. I’ve just put it in the General practice and tests section. Thanks for the suggestion!


The current reading is going into its last week so it is time to open the votes for what to read next :slight_smile:

Since we read about computers and some of their use case for the last couple of weeks, how do feel about something math related next? Do you like for going something longer again or maybe couple of short articles / exercises instead?

Also, I’d like to propose a small break for maybe a week as I have some high workload coming up for the next two weeks. At least, in case you’d like to go for another book.

How do you guys feel?


Math sounds good to me! Usually I’m in favour of books but I’m trying to save some money (not a fan of ebooks, and constantly ordering books from Japan is quite expensive) so I’d prefer some kind of online resource.

Does anyone know if there are any popular science blogs or magazines in Japanese that also cover math topics? I thought that reading a few articles from something similar to Quanta Magazine would be fun but I’m not that good at googling stuff in Japanese yet so I’m not sure if that’s an option.

A break would definitely be nice, we could also go for a two week break if you want to.


Selectable, copy-pastable text, I guess? (I don’t have any particular resources in mind at the moment though. I wonder if NHK for School has high school level stuff that isn’t hard to understand. I think that would be a good balance between being intellectually stimulating and not too advanced for Japanese learners.)

I was already thinking, maybe it would be a good idea to read a Wikipedia article about certain subjects, e.g. basic calculus or the like?
(Having said that, I haven’t looked at the quality of the maths articles on Japanese wikipedia, but at least the German and English ones are usually amazingly good and detailed.)


42 is absolute thruth answer checkmate everyone.


I like that idea! From the few I’ve looked at so far, they seem to be on a similar level as German/English ones


That sounds really nice. I feel that reading books without hearing it might ‘cement’ bad pronunciation. It has Japanese CC (not only generated). So it would be win win.

Reading a wiki sounds also good. Would be fun to refresh my memory on basic combinatorics or probability…

I like the different ideas as well and I am thinking if we might can combine them…

I looked into the first couple of videos and I agree, they might provide a nice vocab introduction. They do have Japanese subtitles so we could do a combination of listening practice and “reading” the Japanese subtitles.

So far they cover four different parts

  • Basic terms and classification of numbers
  • basic geometry terms
  • basic statistical terms and data visualization
  • basic algebra terms

Thanks for looking into it. I like the idea of reading some WP article.

How about the following: One week we start with going through some of the videos from the recommended “math in Japanese” YT channel (those that belong to the same part) and the following week(s) read up on some related topics in the Japanese WP?

→ The video gives us some basic overview / reminder of some needed vocab items
→ The WP article gives some more in-depth information on the topic itself

I’m not really familiar with NHK for School (yet) but I took a brief look into it earlier today. Looks like the videos are more into applying math to situations / tasks in everyday life.

Again, maybe we can find videos over there that are (somehow) related to one of the WP articles we are reading and then go through the video afterwards.

Could be something like the following:

  • first week: go through one of the parts on the YT channel
  • second (- nth) week: read interesting article(s) on WP
  • n+1st week: go through so examples to apply the previous learned stuff, e.g. video(s) from NHK school or link it to some CS related topics or…
  • in case we like it: repeat but with different topic

Does this make sense? Would you be interested?

Thanks. We can decide depending how you and others will be available as well :slight_smile:

Feel free to join us. I’m quite confident practicing won’t make it worse :upside_down_face:

Should we setup a poll (or decide in any other way) what to continue with.
Even at a slow pace it would be nice to increase knowledge in math/CS japanese vocab. As they say in japan 継続は力なり :slight_smile:


Sure. Thanks for the heads up. I’ll start with a Poll for starting date. And maybe later or tomorrow I can create a Poll with the content-wise options we’ve been discussing. Or in case one of you like to create the other Poll feel free to do so :slight_smile:

When to start with next math related readings?
  • June 16th
  • June 23rd
  • June 30th
  • Just here for polling… please ignore my votes

The poll auto-closes next Monday. In case multiple starting dates are fine with you feel free to click them all. In case you don’t want to read but still want to poll please mark the respective option :innocent:

Here is a proposal for some math related readings:

Week Material
01 Maths in Japanese - Chapters “Math 1.1 - 1.4”
02 自然数 (Japanese Wikipedia article)
03 Maths in Japanese - Chapters “Math 2.1 - 2.2”
04 三角関数 (Japanese Wikipedia article)
05 Maths in Japanese - Chapters “Math 3.1 - 3.2”
06 正規分布⁺ (Japanese Wikipedia article)
07 Maths in Japanese - Chapters “Math 4.1”
08 ベクトル空間 (Japanese Wikipedia article)
09 Bonus: 複素数 (Japanese Wikipedia article)

⁺marked as “citation needed” → I still think it would be a nice fit

As for the Wikipedia articles: some of them tend to be quite long. My suggestion would be to either split them up or only read parts of them. For example: vector space: only read the introduction + definition + some examples sections… or something like that.

I’d like to finish with the article about complex numbers (or parts of it) as it gives us a smooth transition into some CS related topics. But it also depends a little bit on what we decide for going afterwards… :slight_smile:

And finally the Poll but feel free to discuss the proposed schedule first (it has no automatic closing date).

Math reading proposal
  • 1: I’m in and the schedule sounds good to me
  • 2: I’m in but I’d like to split the Wp articles into multiple weeks or only read parts of them
  • 3: I’m in but I’d like to read other (Wp) articles → see my suggestions → in case I did not make any my vote is equivalent to option 1
  • 4: I’m skipping this one
  • 5: Ignore me … I’m just clicking a poll every time I see one :upside_down:

Yeah, the wp articles look scary. I would probably spend a fixed amount of time on
that week on it(like an hour or two), stop and wait for the next week’s content.

Thanks for sharing. In case the majority goes with option 1 we can still make recommendations which parts to prioritize. So people who only have time to read part of the Wp article can focus on these parts.

And to be open from the beginning that’s probably what I will end up doing since the Wp article look quite a bit over my level kanji vise. Don’t want to stop others from reading the full article, though :slight_smile:
