UPDATES FROM THE COMMENTS
The most important update comes from a comment by Rosie Fay, who spotted that cipher 1 is just a cycle on 90 symbols.
What does that mean? We often write codes in two-row notation like this
Plaintext: ABCDE
Ciphertext: DAEBC
But we can write that as two chains: A becomes D becomes B becomes A, and C becomes E becomes C.
Or more compactly we write (ADB)(CE).
Barbie cipher 1, is just one long chain, using 90 symbols, like this:
mjvgxdlbcorneaithsfpuqkyzw;¢+%:,W.MZBFCA (right angle bracket) RSETHONILDUGYPQKJV (left angle bracket) X1234056789-¨§£€='_)(*#@?/^!&"
RUclips doesn't allow the angled brackets in the description so I wrote them out, but that is meant to be one chain of 90 symbols.
Rosie Fay then also spotted that cipher 2 is cipher 1 applied twice (we call that the second power).
Cipher 3 is cipher 1 applied three times (third power).
And cipher 4 is cipher 1 applied four times (fourth power).
So there are some fun things we can discover from this.
1. We can apply the ciphers in any order, and order does not matter (they are commutative).
For example, cipher 2 followed by cipher 4 is the same as cipher 4 followed by cipher 2. In fact they are both equal to cipher 1 applied six times.
2. If you applied cipher 1 90 times, you would get back to the original message.
3. The decryption cipher for cipher 1 is cipher 1 to the 89th power.
The decryption cipher for cipher 2 is cipher 1 to the 88th power.
The decryption cipher for cipher 3 is cipher 1 to the 87th power.
The decryption cipher for cipher 4 is cipher 1 to the 86th power.
And you could think of these as eight different ciphers. But they work in pairs to code and decode.
So glad to see you back more active on RUclips. You are one of my favourite educators and communicators on this platform.
True. And that smile :D
I would have KILLED for this as a kid. Just think of the times I would have secretly typed "ASS" and given it to my sisters....
It's a pretty great toy, isn't it!
Awww, that's cute! Like a pink enigma machine, but for monoalphabetic cipher.
It is! That would have been a good video title.
Come on, Barbie, let's go crack ciphers!
Ah, e, nig, ma
I feel like secret ciphers are exactly the sort of thing that kids would want. Or at least, the kind of kids that would be interested in typewriters in the first place. That whole "sending secret messages to friends" thing was part of marketing for other toys/devices for kids when I was growing up, at least. I think the Barbie people missed an advertising opportunity.
Turing Barbie is my favorite doll!
Now I want a Barbie Enigma Machine too! 😀
I enjoyed hearing about the Barbie typewriter, even though it isn't my ken.
GCHQ is absolutely furious that their technology secrets have been revealed. All those banks of Barbie typewriters are now useless.
I love that you coordinated a pink shirt with this episode :)
What a fun secret! I never had one of these as a kid, but I did learn to type old-school on the machines with physical type bar keys that would jam up if you typed too fast. Thanks for introducing us to Sarah--I'll check out her channel and relive pieces of my far distant youth. Also, nice touch wearing pink and using a pink note card--excellent theming.
The speak-n-spell I had as a kid had a cypher mode as well, it was in the instructions.
You win James. The _nerdiest_ message ever encrypted: "typewriters are cool". Thank you!
Thank you soo much! The course is definitely for me :)
I never got to have one of these as a kid, but the Raspberry Pi 400 is pink and kid-friendly
How fitting I was in the middle of listening to "Enigma" on The Imitation Game soundtrack when I clicked on this video!
Shouldn't this kind of code be symmetrical? So 5 to 8 would be encodings as well, and 1 to 4 would be the corresponding decodings.
Typewriters survived in offices because it's the easiest way to make a one-off envelope. You can type the address directly on the envelope, rather than figure out how to make a document and print it properly, and feed the envelope through the printer.
Ha. I didn't know that. I like it.
Very interesting. Great Job, Jim.
i would love you to make a video on how to help people conceptualize large exponential numbers. For instance, there is a Wikipedia artice on the ultimate fate of the universe. But the numbers are so insanely vast, it's hard to draw any real meaning from them.
It is the Barbie version of the Enigma machine.
I want someone to come up with firmware for one of these where you type in all of the necessary key information and then it will emulate an enigma machine.
Nice!
If anybody is old enough to remember "Speak and Spell", that also had a very simple "secret code" function; again, it was a monoalphabetic substitution cipher.
I used to be able to break Speak and Spell code messages in my head, probably as quick as you could enter them into the S+S machine with its slightly awkward membrane keyboard and 8-character display!
We used to be so easily amused! 😂
Oh I didn't know about this. i didn't have a speak and spell. I've just done a google, and it was one button for coding and decoding - so a self inverse code. Very enigma.
I've paused the video at 7:45 before she decodes the message, and I believe the message is "typewriters are cool". I'm just quickly eyeballing it, so haven't confirmed everything fits, but that is my guess. Now to see if I am right...
Well played?
I was not going to watch this, then I saw it was Singing Banana, so I had to.
I envy you, mate. That typewriter is somethin' else. Also, very cool video!
I fascinated that it has a section sign "§" key. Is it a commonly used key in the UK?
All you need is a pilcrow "¶" and you could write legal code on a Barbie Keyboard
No, not common at all.
Oh man, thank you. I was confused by that symbol.
Nice catch. The section (paragraph I'd call it) is shift+3 on German (and probably some other) keyboard layouts, where the pound sign would be on an English one. Not really useful for anybody but lawyers. But what else to put there? The Euro € was not yet introduced, when this layout was established.
So I guess it was included out of principle to serve the German market. Even if nobody needs that as a designated key.
Imagine the disappointment of Nazi cryptographers who invented Enigma seeing their machine designed to help genocide turn into a pink toy.
What I wonder is, if you have one of these typrwriters and the decoding is somehow not functioning, could you enter the coded massage and reenter the output iteratively, would you eventually get the original message?
I like this question. We've discovered in the comments that if you did the code 90 times, you would get back to original message.
It will be even cooler if there is a function of messenger between Barbie typewriters.
Well, there is the im-me, loved by hackers for doing all kinds of weird radio stuff
Barbie telex
James please do a video about your Felt and Tarrant (or Sumlock) Comptometers (old mechanical calculators) that I've seen in the background of older Numberphile vids you've done.
No you not age? Haha Also thank you for promoting education free or paid. You are brilliant and we are fortunate to have your content
The tiles in the background are arranged differently from the last video- is there a secret code here?
So this is what you meant by "secret" in the last video. Should've guessed it was about cryptography!
Haha! What a sneaky clue.
So, the arrangement of the grey tiles in the sound baffling has changed from the previous video... These are the first and second arrangement. Who can guess the next one?

I was really hoping the special guest would be Barbie
Why am I not surprised that the "B" key on the Barbie typewriter is marked with her trademark initial?
Great video and wonderful guest. One thing that shocked me is that Sarah is a hunt and pecker! Or maybe she types like this on camera as not to obscure the keyboard while typing?
(no, I'm definitely a hunt and peck typer on typewriters..... I can't seem to break the habit!)
@@JustMyTypewriter I never learned to properly type, don't feel badly. I am a software engineer, and started with computers in the 1970s, and somewhere in my life, of constantly typing, I learned some "type without looking" method of my own, and I am not going to change it now. I use both hands of course, and my brain simply knows what to do, after decades of typing programs and emails and documents and online stuff.
I wonder if the codes are commutative. If you did code 1 followed by code 3, could you decode them in either order?
Good question. After a bit of investigation in the comments, we've discovered they are.
@@singingbanana upon further reflection, that makes sense since they appear to be simple substitution ciphers, even if they do involve more of the keyboard.
Substitution don't commute in general, so you do have to check.
@@singingbanana you’re right. I wasn’t thinking.
I paused at 8:04 and try to find any pattern
Then I found that code 4 for the character : is wrong. It should be M instead of N
Like me, there are many high school and university students following you from Turkey. I know that they are also fond of mathematics like me, so I would be very happy if you add Turkish subtitles to your videos. I am writing this comment in translation.
"I've made a short online course about crypto-"
Oh?
"-graphy"
Oh. Well that's good too.
How to set back default mode again?
Shift lock 12
I thought the name Barbie was going to refer to Klaus Barbie
That's actually 8 cyphers ;)
True!
I love how you say "children" and not specifically "boys" or "girls". This is a cool toy for all Genders!
Please change the name of channel to " doosie banana ", it sounds more catchy... and funky.... in today's standards
on a completely different subject, your 56th birthday falls on the same day of the week as your birth. why? thanks
