Trivia nitpick: The distress code is not SOS. SOS would be ".../_ _ _/..." However, the distress code is "... _ _ _ ..." -- that is, there are no pauses between sections! This is usually represented by placing an overbar above the letters, to indicate that the operator should not insert pauses.

First time Derek gives his own opinion about something in the most Gen Z way possible (at least for a middle-aged man). Also, I always thought SOS was "Save Our Souls".
It's so great to see that the evolution of humanity and science itself only gained efficiency and robustness through the communication being efficient and robust. Transfering information was the reason we, as a species, turned out to be more evolved than other species and now it's the reason we can have such advances in knowledge that a computer can create paintings and communicate in natural language using artificial inteligence. I wonder what's the end of it... will we ever create a supermassive inteligence?
1, I have always loved QR codes. I even practiced how to read them. 2, One of my favorite games ever is an extremely underrated, philosophically-driven story, puzzle game called The Talos Principle. That game uses QR codes as messages on walls for AI to speak to each other. It's an amazing game. I highly recommend it for everyone who enjoys puzzle games. It is similar to Portal 2 and other great puzzle games.
The Talos Principle is one of the best games ever. Playing through the 2nd one now. If you liked TTP, I can't recommend Outer Wilds enough. Don't google it, every little bit of information is a major spoiler. You'll have to trust a random stranger on this one
12:25 people keep sending me this 😅 probably should've mentioned MattKC so that people won't confuse this with my snake-in-a-QR implementation (and also because credit is due)
I like them because they're mostly more up-to-date and often include photos of the dishes. Additionally, you don't need to wait for the watier to bring the menu, and they also don't take the menu away, which they do in my country after you ordered.
It was fine idea during the pandemic when you wouldn't touch the menu. Also if you travel, in restaurants they usually have a menu in their local language plus one in English maybe. But imagine there's like 6 billions of people in the world that can't speak or read English. With QR codes You can have your menu in all the languages. Isn't that neat?
In my country, Kazakhstan, QR codes are used extensively, especially in banking, and we take great pride in having developed such advanced infrastructure. I believe we were one of the first countries to implement QR codes on such a large scale for everyday transactions.
13:00 is he not using the go board wrong? I thought pieces were placed at the intersections of lines. The guy literally said that earlier. Now hes putting them in between squares
He's probably doing that because that makes it into a 25 x 25 grid, exactly the right size for a version 2 QR code. He must have also had to find a somewhat unusual Go board for that, since most of them are 19 x 19, not 26 x 26 like that one.
It's unsafe in the way any text instructing you to do something on your phone is unsafe. They are just easier to use. When people see a sketchy shortened link in public they won't visit it. Not because they are smart but mostly because it's just to much effort to exactly copy these random characters. Qr codes remove that barrier. So if you don't know what you are doing its best not to scan random codes. But if you do know then it's mostly safe.
33:28 as soon as the black and white barcode and qr code was mentioned. I thought; 'why not add colour). Humans can detct red blue and green colours via cone cells. As well as gradients between black and white. Light and dark via rod cells. Other animals like pigeons can see yellow. If you can implement this, you can have a functioning eye. This can also affect information density and biorganic/cybernetic computers. Sensors being cone and rod cells and wires being nerve cells or slime mold. Maybe even carbon nano tubes or spheres. Maybe muscles or organic mercury as it is a metal and therefore could pass electrical signals easier. Batteries could come from electric eels. Elctrical sensors could come from sharks although it would only work in salt and brackish environments. As per my understanding of this area. This is mainly my mix of engineering, computing, mathematics and science fiction (mainly Frankenstein and Warhammer 40k) merging.
11:28 ASCII is a 7-bit encoding, 8-bit is known as extended ASCII and there are many variants of it like windows-1252 etc. Btw, URLs are also case-insensitive, so you could probably went with 5-bit encoding)
If you had the qr code encoded as bytes and made a custom app to decode it, yeah. But the utility of a qr code in the vast majority of cases comes from your phone camera being able to scan it and decode it and send you to a url, so you have to use the typical ascii encoding for that.
@@JazzyMaxine there is alphanumeric encoding - 11 bits per 2 characters, as mentioned 3 minutes later. Also, I'm pretty sure I saw non ASCII chars in qr-codes, UTF-8 probably would work just fine.
30:18 Correction: He said Tokkyo (特許 patent), not Tokyo. The entire sentence is: We made the patent open to everyone, which made the QR code so popular.
0:35 yes, in India we have been using UPI to process transactions through QR code since 2016. It hardly takes 2 seconds for the transaction. And, it's free too.
23:22 syndrome. Foes this apply to dna. Could you write out the 4 dna/rna or 6 if you include the x and y or z artifiactial rna scientists created. The using this formula find out if a mutation has occured. If the end result is not what you expected, you have proof that a mutation has occured. Is this also the reason why dna related effects are called syndromes? What about downs syndrome. I know that some dna related problems can be called degenerates or degenerative. Or something similar. (Did A-level biology 3 years ago). I can't be the only one thinking this right?. I know that rna and dna can be treated like codes as there is a code substation or reversible website that changes binary hexcidecimal rna/dna and other codes. It was used for some puzzle games. The website was linked for the game. Can't remeber what game it was.
I dislike qr codes since with modern computers, a high amount of data and data correction could be stored in a small amount of space. It seems totally inefficient. Also they normally just point to a url which seems like cheeting. It would take less space just to write the url in text and scan the text. It is like using more code to download an image. It can be done but it could be done much faster and more efficiently. Just about every technology we use is that way, it's a hangover from past tech. /Endrant
theyre ugly and intrusive. also when they first came around most phones didn't have qr scan built in, so usually trying to read a QR meant taking a picture and doing a reverse image search or something. Or having to download a QR reader. having to use another app to get to a website instead of just reading a website name on a sticker didnt seem to make much sense. when QRs first started going viral, it wasn't usually phone to phone. QRs were stickers posted on subway walls, cafe pinboards, or checkout counters. Just noisy and intrusive.
Me and my freinds use to try to make random qr codes on a Go board and scan them to see what came up, the most random thing we found was a login page to some random german school
Veritasium was the one who made me interested in science since childhood and he keeps doing it to younger ones. Great work Derek btw as always its awesome.
They're just another way to express data just like a barcode. Unfortunately, they're SUPER unsecured. 🚩☠️🚩 I don't recommend them for anything other than what barcodes were initially designed for... convenience in identifying simple information.
Well I would say that some scanner apps are not secure because they open links from qr code without asking. QR code in itself is not insecure. Or am I missing something?
The main problem with QR codes is when a creator puts them in a video, and doesn't provide a link in the description. When I'm watching on my phone. Also, Japan was using QR codes for years before they were widely adopted in the west.
Bit weird to me to use an image to represent an image. It's basically a tool to convert a picture to binary. To then encode that binary into an image sounds wasteful

Maybe muscles or organic mercury as it is a metal and therefore could pass electrical signals easier. Batteries could come from electric eels. Elctrical sensors could come from sharks although it would only work in salt and brackish environments. As per my understanding of this area.
This is mainly my mix of engineering, computing, mathematics and science fiction (mainly Frankenstein and Warhammer 40k) merging.
Scan at 13:00
3:41 sos isn't actually morsed ... --- ... , but ...---... so without any pauses between the o and the s, like it was one letter
11:28 ASCII is a 7-bit encoding, 8-bit is known as extended ASCII and there are many variants of it like windows-1252 etc.
Btw, URLs are also case-insensitive, so you could probably went with 5-bit encoding)
If you had the qr code encoded as bytes and made a custom app to decode it, yeah. But the utility of a qr code in the vast majority of cases comes from your phone camera being able to scan it and decode it and send you to a url, so you have to use the typical ascii encoding for that.
Alphanumeric encoding encodes 2 characters in 11 bits.
@@JazzyMaxine there is alphanumeric encoding - 11 bits per 2 characters, as mentioned 3 minutes later. Also, I'm pretty sure I saw non ASCII chars in qr-codes, UTF-8 probably would work just fine.
@@P1XeLIsNotALittleSquare UTF-8 is 8 bits tho so no gain. Also I wasn't aware alphanumeric included the special characters which can be in URLs.
@@JazzyMaxine utf-8 is a variable length: 1 to 4 bytes per symbol. It can encode pretty much all unicode symbols
30:18 Correction: He said Tokkyo (特許 patent), not Tokyo.
The entire sentence is: We made the patent open to everyone, which made the QR code so popular.
TY, that makes so much more sence
2:00 “…Breese Morse…” what a strange na… OH HE’S THAT ONE
only veritas can make the history of QR codes an interesting watch.
0:35 yes, in India we have been using UPI to process transactions through QR code since 2016. It hardly takes 2 seconds for the transaction. And, it's free too.
0:19 "QR codes are a language for machines, and I am a human. But I was wrong."
Can't imagine what it must have been like to realise you're not human.
23:22 syndrome. Foes this apply to dna. Could you write out the 4 dna/rna or 6 if you include the x and y or z artifiactial rna scientists created. The using this formula find out if a mutation has occured. If the end result is not what you expected, you have proof that a mutation has occured.
Is this also the reason why dna related effects are called syndromes? What about downs syndrome. I know that some dna related problems can be called degenerates or degenerative. Or something similar. (Did A-level biology 3 years ago).
I can't be the only one thinking this right?.
I know that rna and dna can be treated like codes as there is a code substation or reversible website that changes binary hexcidecimal rna/dna and other codes. It was used for some puzzle games. The website was linked for the game. Can't remeber what game it was.
I dislike qr codes since with modern computers, a high amount of data and data correction could be stored in a small amount of space. It seems totally inefficient. Also they normally just point to a url which seems like cheeting. It would take less space just to write the url in text and scan the text. It is like using more code to download an image. It can be done but it could be done much faster and more efficiently. Just about every technology we use is that way, it's a hangover from past tech. /Endrant
31:54 That could be a good use for the last unused bit. If it's black, unencrypted. If it's white, encrypted.
new record, got a headace after a whopping 22:50 minutes!! lets go!! aiming for 30 minutes next video
Right there with you brother 🙌🏽
When are we gonna get an information theory video?
Especially if he can work in the relation between that and black holes!
am i the only one who scanned every QR code in this video ?
The Snake QR code guy is named MattKC and he has a has a RUclips channel. I’m sad you didn’t shout him out he has a lot of really cool stuff on there.
So, what will happen if I scan the stripes of zebra through a bar code reader?
😂😂
23:43 37 spotted
Indeed
Why would a science enthusiast like you hate QR codes for absolutely no reason ;)
He literally gave you the reason.
Hey you gotta shout out MattKC. It's cool that you mention his stuff but he makes his money from his videos, and you gotta credit him.
I have to be honest, about 20 minutes in I started hearing Flight Of The Conchord-Robots with all the zeros and ones 😂
I'm going to make a t-shirt that has a QR code that goes to a ransomware site.
DO IT
That type of quishing has already been done.....
Why would you hate QR codes in the first place?
theyre ugly and intrusive. also when they first came around most phones didn't have qr scan built in, so usually trying to read a QR meant taking a picture and doing a reverse image search or something. Or having to download a QR reader. having to use another app to get to a website instead of just reading a website name on a sticker didnt seem to make much sense.
when QRs first started going viral, it wasn't usually phone to phone. QRs were stickers posted on subway walls, cafe pinboards, or checkout counters. Just noisy and intrusive.
ignorance
Scammers
Intrusive? @@maxonmendel5757
35:12 bro wtf
Me and my freinds use to try to make random qr codes on a Go board and scan them to see what came up, the most random thing we found was a login page to some random german school
So 2 Japanese engineers gave birth to 2 greatest inventions in the 20th century: QR codes and white LEDs
Fun fact: the vibration pattern in an "old" phone when receiving a text (br br br brrrrr brrrrr br br br or ... -- ...) is morse code for SMS
12:20 "one programmer" sad MattKC noises.
Morse code at 3:12 is " what hath god wrought"
Veritasium was the one who made me interested in science since childhood and he keeps doing it to younger ones. Great work Derek btw as always its awesome.
I thought I already understood QR codes as a techie. Boy, was I wrong! The error correction is insane!
12:23 I knew he was gonna mention MattKC! But he should have given more credit.
Great video! I learned more about QR codes and other coding methods than I thought I would ever need to know 😁
My smooth brain began to slowly implode from 18:16 onwards
yeah dude too much math
33:22 they are making qr codes woke
Absolutely great Japanese invention.
I hate them on restaurants, though. They should have physical menus or at least Tablets.
3:05 The Morse code for the comma is incorrect. It should be dash dash dot dot dash dash.
I don't know why, but "SOS" not being an abbreviation of something really annoys me :/
He is wrong. It stands for "save our souls"
@@AlanBarker he isn't technically wrong, It's a backronym
12:50 MattKC mentioned? Let's goooo!
Imagine with QR code we can use toilet paper for data storage!!!
Annnnnnnd Rick Rolled....classic
They're just another way to express data just like a barcode. Unfortunately, they're SUPER unsecured. 🚩☠️🚩 I don't recommend them for anything other than what barcodes were initially designed for... convenience in identifying simple information.
Well I would say that some scanner apps are not secure because they open links from qr code without asking. QR code in itself is not insecure. Or am I missing something?
The main problem with QR codes is when a creator puts them in a video, and doesn't provide a link in the description. When I'm watching on my phone.
Also, Japan was using QR codes for years before they were widely adopted in the west.
"And now we have a working QE code. Try it out!" He says to me while I'm watching on my phone, and thus can't turn the camera on the screen...ffs
Who all tried to scan each and every QR Code in the video? 😅
I'd always assumed they were somehow related to QR decompositions
didn't bud few minutes a go changed the thumbnail?
Bit weird to me to use an image to represent an image. It's basically a tool to convert a picture to binary. To then encode that binary into an image sounds wasteful
Was looking for this. Also, can't medical images of patients simply be transferred to radiologists as image files (DICOM perhaps)?
I bet you that someone will scan every qr code in this video😂
I'm pretty sure 99% of viewers watched that math segment without understanding a thing but kept watching
Wow man you're so cool
Only ogs will know the thumbnail was changed
