- 12 Days of Curtsmas Chapter 11: Variations & Marketing
This is a Curta Type I, built in 1952. Thanks as always to the person who gave me the Curta.

I am recovering from stomach surgery and your reaction to the furry question caused massive amount of laughter and massive amounts of pain
My wife is also recovering from stomach surgery; I hope your recovery is fast!
@@farpointgamingdirect thanks! just had coffee for the first time since the surgery and that made me feel so much better, hope your wife recovers fully and quickly
I just shared that "I have a good counter" with practically everyone I know. None of them laughed and I don't care, they're wrong.
yeah this one killed me
3:19 This 24-second delayed response is pure cinematic excellence!
It was that short? I went out to the kitchen and made a sandwich while he was pausing.
@@johnsrabe No man!!! Ya gotta sit there and take in the whole of the perfect pregnant pause!
@@Nashvillain10SE (I was just joking about the sandwich. I did sit there and look at him for the whole 24 seconds. It was awesome. But now I’m hungry for a sandwich!)
@@johnsrabe 😂 I assumed you were joking as much as I was using hyperbole
@@Nashvillain10SE Sometimes I need people to hold up a sign saying “hyperbole” or “joking.”
"This is a question worthy of discussion". Ends video.
As if to say, "I'm already on it!" There's one more Curtsmas day remaining.
Best to end before stumbling to the wrong side of the internet
Something else, too ……..
“not a collector of calculators”
but has a
“small collection of staplers”
When does”a bunch of stuff” become “a collection”?
And could we chat about priorities?
@@chriswalford4161 It all comes down to intention
@@Nashvillain10SE For me, the line between collector and hoarder is being able to tell stories about the items. (Not meant as a judgement, it was just a useful distinction for convincing friends that I had not become "a crazy cat lady, but with keyboards" :-)
this Q&A should happen more often. Yes they may get repetitive but still...
That was it, my one moment in the spotlight... And there's a typo in my comment. I have brought shame to my ancestors.
The Furry art OMG
If you ever happen upon one going cheap, would you consider picking up a Vari-Typer (and then making a video about it, and then divesting yourself of its physical burden I guess)? It's an early typewriter for composing justified text, I first read about it a few months ago, when it didn't even have an english-language wikipedia page (I've since thrown one together).
I think it'd fit the channel, since it's performing calculations mechanically, and also that its historical significance has flown under the radar somewhat - they descended directly from the first justifying/composing typewriter developed through patents and company ownership changes, and prior to them, getting some justified text printed meant paying a print shop to typeset a page and run a press for you. I think that's a significant sea-change! I'll probably never see one over on this side of the ocean, but there's a chance you might.
There's a manual on the Internet Archive for a 1940 model ("Care and Operation of the Vari-Typer") which is worth a look, and I'm pretty sure they typeset the document on one of their machines, then had it photoreplicated, as a flex. It is recommended that you use A. B. Dick correction fluid!
Looks interesting!
Curta
Still got it!
Curta translates to like in English.
Why do they all collect curtas? Because what's cooler than a math grenade with KNURLS!
chris has a fursona now
Of course we all know the one about the student who needed to get as many points as possible so they decided to use their slide rule for every calculation, no matter how simple. A teacher standing nearby heard the student muttering: "So two times three is five point nine nine nine nine..."
3:37 😳 …
You are a comedic genius … 😅 thanks for the Seconds Of Silence … 👍
I’m telling you, Vegas Is Calling.
Thumbs up! More mailbags in the future, I hope.
Exactly! Happy New Year to you & yours, amigo! Stay well!
dude i love your channel so much. you got an incredible thing here
Thanks Chris! I love your style (and content). Keep doing what you do. Happy Holidays!!!
Great vid
Hilarity is taking a group of mathematicians and asking them to calculate an 18% tip.
You don't use them bones around the house like when doing the check book?!
@3:55 I went back as a non-traditional student to finish a math undergrad in my early 30s. I found that it oddly made me much worse at mental math, prior to that I was working in the trades so ended up needing to regularly do mental math, but the types of math you end up doing for a degree are normally not focused on precise numerical answers so that is a skill that ended up degrading. Anymore if I end up needing a precise answer, I'll either use a calculator or write a script, but normally I'm not as interested in the numerical answer.
Chris's fursona reveal
About the carry switching in subtraction mode, isn't the real difference not so much the carry itself (since the Curta basically subtracts by adding), as the way it has to advance the least significant digit wheel by an extra 1 in subtraction? I guess you'd have to get into that, regardless.
Well a subtraction needs to borrow instead of carrying.
@@ChrisStaecker Yeah but the Curta is using the method of complements so it's just adding the complementary number plus 1, right? So unlike a pinwheel calculator, it only has to use the adding type of carry, unless there's another wrinkle I'm missing. The carry propagates all the way through the digits and falls off the left edge of the world. The extra thing it does have to do in subtraction, though, is handle that plus 1, and there's some extra machinery for that.
@@MattMcIrvin This is it. The carry drum is independent of the stepped drum’s shift. The stepped drum is solely responsible for the 9’s complement and the +1 in subtraction mode, the carry drum handles carry the same in both modes. It’s basically a lever that is pushed by the result wheel when it reaches 0, and it pushes a gear onto the path of a single carry tooth. The tooth is positioned such as any gear is first engaging the stepped drum, then the carry tooth, but never both at the same time.
@@LarsTheOctopus It seems like most of the complexity of the carry mechanism is just to make the carry ripple through from right to left in an orderly fashion instead of all the carries happening at once (which would jam everything up).
@@LarsTheOctopus ...Someone in the comments on another TH-cam video mentioned that the Curta manual actually tells you to do long division by a method that involves constructing the dividend with repeated addition of the divisor, instead of removing it with repeated subtraction, to reduce wear on the mechanism. I guess that makes sense if every subtraction has to carry through all of the leading zero digits.
A slide rule doesn’t have sufficient precision for many applications.
More generally, a slide rule can't *add* at all, just multiplication-like things (including some trig and exponential functions.) (It might be interesting to compare a slide rule with "a curta+log tables" for precision...)
@@MarkEichin I have 7 place log tables-fun.
@@MarkEichin It's interesting to ponder *why* slide rules can't add. After all, it would be easy to make them add: just put two linear scales on there. Most of them already have one linear scale, for computing logarithms. But nobody bothered to give them an addition feature. Why not?
I think the answer is that, the way you generally used a slide rule, that wouldn't be very useful. It can only give you about three digits and setting up the calculation wouldn't be that much faster than adding three digits on paper--also, doing anything else on the slide rule would destroy your result, so it's not a functional accumulator to remember your total. There were already super simple devices like Addiators that were better at adding than a slide rule would be. Better to just use one of those, or a piece of paper.
Obviously the curta furry should be feline. A curta-cat if you will.
I guess I need to be more like @getjaketospace
