Travelling down the rabbit holes of the internet and ferreting out stories
The (Mostly True) Legend of the Red Ghost
In the 1880's, a mysterious beast called the "Red Ghost" terrorized the people of Arizona. Local legends claim he was a giant red horse, thirty feet tall, with a sun-bleached skeleton riding in his back. Stories of the Red Ghost spread all over Arizona, until one day in 1893 when a local rancher shot and killed the Red Ghost, only to discover he was actually a camel. The pale rider was a human skeleton that had been tied to the camel's back.
Nobody knows how the dead man ended-up tied to a camel's back, but we do have a good idea of how a camel ended up in Arizona in the first place.

Sangaku: Japanese "Sacred Geometry"
Переглядів 3,3 тис.2 роки тому
In Edo-period Japan, shinto shrines were often decorated with small wooden plaques called sangaku which contained challenging geometric puzzles. Whether the purpose was for the gods, or for other congregants is unclear but the math they used was based on Japanese techniques called wasan. At the time, Japan was closed-off from the rest of the world under an isolationist foreign policy called "Sa...
Biomimicry and Burdock

Through creative innovation, humans have found ways to use even pesky plants to their advantage. The briars of the burdock plant can be a nuisance, especially if you have a pet with long fur, but using biomimicry humans used burdock to create better fasteners. Poison ivy is a quick way to ruin a camping trip, but when it was repurposed by Japanese craftsman it led to Japan's chief export in the...
Kaktovic Numerals

In the 1990s, a group of middle school students in the small arctic town of Kaktovic Alaska created their own number system to better reflect their own Inupiaq language which uses Base 20 instead of Base 10. The result was was an elegant writing system that may even improve how we teach mathematics. In just two years Kaktovic test scores went from the 20th percentile to above the national average.

God I wanna visit Japan so bad. I'm too young to have any interest in retro gaming outside of a historical sense, but its great to see you exploring your hobbies!
There's definitely something for everyone here. I've lived here for almost 20 years and still find things to surprise myself all the time. I hope you make it out to Japan one day.

I gotta love unique obscure history. With your video concepts and video production, I would think your channel would have orders of magnitudes more subscribers!
I appreciate that feedback. Maybe we'll get there one day, but for now I am just happy people are watching and enjoying the videos. Especially people like you who take the time to leave kind and considerate comments! Thanks again!
Love it when I get a net gain on my camels.
This isn't directly related to your comment, but I remember as a kid watching a movie where a boat abandoned it's entire cargo of horses into the ocean and watching those poor horses desperately swimming into oblivion sort of traumatized me. It's like watching that famous Artax scene from Neverending Story times 100. I don't know what movie that was and never looked it up because I don't want to see it again!
Gonna be honest, the only thing I ever played on my gameboy color was pokemon yellow and silver, even had the pikachu edition gameboy. Man I envy you for having kept yours...
Believe it or not, I actually have never played any of the pokemon games. My younger brother left one in this Gameboy so maybe I will give it a try.
@@ferretsensei I'll say it aged terribly, but growing with it, with the whole phenomenon surrounding it, it's really an artifact of its time. I'd recommend playing either the remakes of the first two gens or, a controversial opinion, but I think the let's go games on switch removes a lot of the tedium associated with those game. While young me would have hated it, grown up me loved it. I already crunch spread sheets all day long, no need to do it again at home. (funnily enough, I am still obsessed with satisfactory in spite of this, go figure)
Happy to see you back. Its good to see creators making content that speaks to them and makes them feel good. Thanks for sharing your journey with us; looking forward to what comes next!
Thanks for the encouraging words. I feel like there are lots of fun stories to be told through the lens of video games.

Thank you so much for sharing your story! I dont remember how I subscribed to this channel a while back, but I am very interested to see what happens next. If nothing happens, that’s fine too. 🎉
I appreciate that. I've got lots of ideas - hopefully they're entertaining!
Welcome back man, happy to see you got better. Really happy to see, as well, that you do seem to have a good support network around you. Anyways, can't wait to see what you do next! Have a good day everyone and a great week end as well.
Thanks so much. Yeah, a good network is essential, and learning how to actually ask for help from that network is the hardest part for me.
Big love from another retro gamin PowerPoint connoisseur.
I think there is a lot of cross-over between retro gamers and PowerPoint connoisseurs!
So cool to see you back! Looking forward to all the cool things you're gonna talk about
Thanks for the kind words. Hope the videos don't disappoint
Good to see you back man. I have my own experiences with depression, so I'm glad you've managed to break through it. Can't wait to see what you create going forward.
Hey fellow ferret! Thanks for the words of encouragement and sharing your own experience. It's always a pleasant surprise how supportive the UA-cam community can be.
So, a numbering system where you don't even have to understand math to get the correct answer to problems?
At least for very basic operations, yes!
Arabs use a different form of numerals than we do, even if they were both introduced by Arab traders
That's always seemed so strange to me, since the numbers used in the West are called "hindu-arabic" numerals!
Do you have any idea if there could’ve been more to why Weil told this story?
I don't unfortunately, but I'd love to know if it is documented somewhere.
It's simply genius (but it looks really boring)
They do all look really similar, it's like if we counted using only tally-marks.
@@ferretsensei I just realised that it could be a disadvantage when you need to quickly distinguish them from afar, like on a digital clock or a traffic sign. Even though we also have similar symbols that can sometimes get mixed up (3 8; 1 7; 3 5...).

It's very similar to abacus.

Coming from Dog People podcast, loved the video!
absolutely ingenious. soon enough this will be taught in schools.
I didn't get how the urushi example ties in with the burdock/velcro story Still learned something new, so gave you a sub.
This is all really cool, but one question. How do you write pie in this numeral system. I wanted to write this to see what cool mathematical arcane scroll of Inuit magic I could make, but due to the number system eventually going right to left when going rather than how we go left to right and add another number to the end. I just want to know if they have solved this problem as well as how they tackle decimal numbers.
Pi in base 20 is: 3.2GCEG9GBHJ9D2... So in Kaktovic it would be 𝋃.𝋂𝋐𝋌𝋎𝋐𝋉𝋐𝋋𝋑𝋓𝋉𝋍𝋂... (You will need a font that can display Kaktovic unicode characters.)
Jerry Lawson did not create the cartridge. Why spread lies?
bro its not that serious lol
Very cool. Question: wouldn't it kind of destroy the whole system to be turning the south pointing chariot off on straightaways? Thereby it can't compensate for small curves on a road, that looks straigt to the human eye? Was this actually used as navigation, or was it just a cool trinket owned for prestige? Anyways very cool device, I should go read about it. Great video.
Fortunately Japan had ababus calculator. Even multiplication and division are surely possible.

Breaking news: local ferret reinvents the brochure industry
Very enjoyable video
I think this video is a good intro to what Sangaku is. Would be awesome if you could discuss Wa-san (Japanese mathematics) and how it evolved out of Zhong-suan (Chinese mathematics) during the Edo period. Many of the research areas and formulas known by the Japanese began with the direct transmission of Chinese mathematics texts from Korea into Japan. As mathematics declined in China during the Ming dynasty (1368 - 1644 AD), it gained popularity in Japan due to the peacetime economy and "demilitarization" of the Samurai class. In fact, many Japanese mathematicians of the Edo period were Samurai.
I would like to correct that Wasan (Japanese mathematics) did independently discover Descartes' Four Circle Formula, but the three circle problem was likely an exercise of the Pythagorean theorem. The formula was explained in Hashimoto Masataka's book Sanpo Tenzan Shogakusho (筭法點竄初學抄) in 1830.
I was listening to this in the background and thinking to myself, "this is would make an amazing comic book." And then I hear your advertisement and was like, "touche, narrator. Touche."
Around 5:30, you don't have to know what number is represented no matter the system(as long as it's a positional number system) to calculate with them, just know what are the digits and the table for all of the digits for each operation. I tried to understand better binary numbers and those were my conclusions, as long as you stay in one number system then you don't have to worry about what is this number in another, like do you think what 10231391 is? It's 10231391 but only in base 10, so as long as we stay in base 10 then it's just it, just 10231391 you know that 1 less is 10231390, and 1 more is 10231392, etc etc One thing, it's best if you have a word system for naming those numbers, so if they are base 20, then naming them in base 10 is switching systems all the time which would be a problem, I used base 10 names in base 2 as going down doesn't make many problems, just is a little confusing
Im stealing someone elses comment from another video and would genuinely love to know how this is solved in Kaktovic "I tried 100 divided by 11 couldnt figure out how to do it.. unless I got something wrong.. the symbols for 11 just never appear in the symbols for a hundred.. heres what I did: so the symbols for a hundred is 2 symbols. the symbol for 5 (one line on top) followed by the symbol for 0 because we are in base 20 so 5x20 + 0x1 = 100 the symbols for 11 is 1 symbol, 2 on top to make 10 and 1 now trying to fit the symbols for 11 into 100 and counting how many times it appears give you 0, it never matches.. it seems to me the examples in the video are cherry picked so they work.. or I messed up pretty badly.. heres another one: 6 divided by 3 6 is one on top + 1 on bottom (5+1) 3 is 3 on bottom they also never match.. theres only 2 lines in 6 so you can never match 3 line in it. you would have to break the 5 (top line) of 6 into bottom lines to make a match, something like: \/\/\/ divided by \/\ to make it work visually it's like if someone showed you how easy it is to divide in base 10 saying you just remove zeros ! and they show you example : 20 / 10 = 2, 300 / 100 = 3, 36 000 / 100 = 360 like that's cool but it really only works for specific cases, again unless I messed up somewhere... (please point it out to me if I did)" it seems whenever you have a zero in the dividend, you have to divide like normal
Yeah sometimes you have to mentally break one or more of the “five” lines in order to get something to appear.
For 100/11… let’s see… (Note: I’ll use - for 5, > for 10, ≤ for 15, and ȣ for 0, as well as \ for 1, V for 2, V\ for 3, and W for 4. Also, sorry for the wall of text.) 100/11 would be - ȣ ÷ >\ . Mentally breaking the -, we get (W ≤W + \) ÷ >\. Let’s split this into (W ≤W ÷ >\) + (\ ÷ >\). Let’s look at the first part first. We can see >\ once in W ≤W, so (W ≤W ÷ >\) becomes ((W -V\ ÷ >\) + \). Next, let’s mentally break the next \ ȣ into two copies of >. We then get ((V\ >>-V\ ÷ >\) + \) (yes, I know KI numerals don’t actually have more than 3 horizontal lines at a time, but please bear with me here). We can see >\ twice in the “ones” place, so we get ((V\ -\ ÷ >\) + V\). Next, let’s break the -\ into VVV and one of the \ ȣ s into >>. We then get ((V >>VVV ÷ >\) + V\). Again, we can see >\ twice in the “ones” place, so we get ((V VV ÷ >\) + -). Next, let’s break another one of the \ ȣ s into >>. We then get ((\ >>VV ÷ >\) + -). Again, we can see >\ twice in the “ones” place, so we get ((\ V ÷ >\) + -V). Breaking the final \ ȣ into >> gives us ((>>V ÷ >\) + -V), which simplified, results in (-W). Adding the second part, \ ÷ >\, and noting that this second part is less than one, we get -W R \. So - ȣ ÷ >\ = -W R \. Yes, it’s complicated, but it can be done 😊
The multiplication table for this is remarkably simplified! You don't need to memorize a 20x20 grid like a base-20 Arabic numeral system would require. Instead, the sub-base 5 system can be taken advantage of and reduce the table to just 37 total products to memorize: 4x4 for each base (vertical numbers), 4x3 for each base x sub-base (vertical * horizontal), and 3x3 for each sub-base x sub-base (horizontal numbers). Multiplication requires you to break up the vertical and horizontal parts of each number and FOIL the now single digits. 6 * 3 would breakup into a 5 * 3 + 1 * 3 = 3 5's (horizontals) and 3 1's (verticals) which is visually the character for 18! 6 * 6 -> 5 * 5 + 5 * 1 + 1 * 5 + 1 * 1 = 1 vertical in the 20's place and 3 horizontals and 1 vertical in the 1's place = 1 (16) in base-20 = 36 in Arabic numerals!
@@dannyshahlestari6679 I can't type Kaktovik numerals, so this will be limited to Arabic numerals for simplicity (either write it yourself or visit the Wikipedia page for a better visual). You only need to memorize 3 VERY small multiplication tables: The ones x ones: | 0 | 1 | 2 | 3 | 4 | ---------------------------- | 1 | 1 | 2 | 3 | 4 | | 2 | 2 | 4 | 6 | 8 | | 3 | 3 | 6 | 9 | 12 | | 4 | 4 | 8 | 12 | 16 | The fives x ones: | 0 | 1 | 2 | 3 | 4 | ---------------------------------- | 5 | 5 | 10 | 15 | 20 | | 10 | 10 | 20 | 30 | 40 | | 15 | 15 | 30 | 45 | 60 | The fives x fives: | 0 | 5 | 10 | 15 | -------------------------------- | 5 | 25 | 50 | 65 | | 10 | 50 | 100 | 150 | | 15 | 65 | 150 | 225 | Again, these will be at most 2 digit numbers because Kaktovik is in base-20. The Wikipedia page at the end of the Computation section gives a MUCH better visual of these tables than what I can do in a UA-cam comment. The reason this works is due to the sub-base of 5. It effectively acts as if the number has been rewritten in a factored form. An easy example to see this would be doing 6 * 6 yourself with the Kaktovik numerals. You'll use the FOIL method to compute (5 + 1) * (5 + 1) to build the value for 36 (in Kaktovik numerals obviously). There's no actual need to memorize that 6 * 6 = 36 (or any other multiplication greater than 5!), and that advantage is only really useful for children still learning their first numeral system. It reduces the amount of rote memorization needed for multiplication, which is certainly easier for children. The fact that it's been reduced by 63% is amazing! Memorizing more multiplication pairs to shortcut some work just becomes extracurricular at that point.
