- This is a super-edit of my "12 Days of Curtsmas" series, cut into a single episode. No new content here. I suppose this is episode 79 of my video series about old calculating devices.
This is a Curta Type I, built in 1952. Eternal thanks to the person who gave me the Curta.

I'd use that for calculating how many miles a long road trip was so I don't have to try to remember to look at the odometer the whole time.
This ties all the videos so neatly together! Nice compendium of knowledge on the device, really one of the best works on the subject on this website!
This was truly excellent and I learned so much. Thanks Professor Chris.
Prof. Chris This was such a deep and touching story, more comprehensive and mathy and human than I could have imagined. Wishing you joy and success in 2024
Curta
Curta 👍
killin' it brother
I NEED one of these things dude! I go into antique stores that sell all kinds of random old trinkets (and trash) and dream about coming across one of these for like $100 or something 😂
I wish.
I dont know why, but I MUST have one.
Your series is fun and full of good, sensible reflections.
At 1:02:25 for the Curta during an expedition to Greenland, those not-so-smart marketing folks added an image of... a penguin from Antartica! There are no penguins in the Arctic. Doh!
-1 being 9 repeating means the curta is p-adic approved.
well 10 isn't exactly a prime number
I thought this was related to digital logic turning a negative number into a positive by finding its 2 compliments then adding the numbers
Amazing!!! That’s content that truly deserves attention. What a value.
This was so amazing and well researched! I agree that this makes more sense to me than the ET hypothesis.
I really loved this "documentary". I learned almost nothing since I read so much on Curta already. But I'll need to get this novel I discovered in your video. I'm also the lucky owner of a Type II one, and I'm still amazed by the mechanical engineering ideas that have been implemented in this tiny device. I spent hours to play with and understand why it has become such a searched objet for collectors.
Nice. Happy new year to you.
it's all adding
You bring people to curta world
Great job!
Amazing explanation and storytelling, what a ride.
Thanks a lot!
This was amazing; thank you. I just purchased a Curta (for which I absolutely blame William Gibson) and this was the best intro I’ve seen. Definitely subbed; which probably means more impulse purchases 🤣
Wait wait wait. Are your 12 videos about the Curta all combined into this one easily-digestable 76-minute video??
Curta 🇧🇷
A Curta should be gifted to the first aliens to visit Earth.
"this little boink:
lmao
Doink
I was searching a video about the gerber graphanalogue but there is none. Did I miss it?
Not yet- someday!
Have you tried dividing by ZERO with it?
all twelve videos were 1h 16min ? A shame, too short! Hopefully there will be 12 more in 2024.
It most definitely is not the greatest mechanical calculator ever made, there are many, many better mechanical calculators, but none as compact. Curtas have a huge cult following, which has pushed their market value way beyond what they are worth for the facilities. The biggest failing of the Curta is the lack of back-transfer facility, something that is necessary for chain calculations, and the lack of reset facility on input.
What's your pick for greatest? Top 5 maybe?
I mentioned the lack of back-transfer is significant. Input reset doesn't seem like a big deal to me- but an underflow bell would also be nice. To me "greatest" isn't just about how useful it was at the time- I am judging it by my own modern standards, which naturally has very little to do with actually using it for important calculations.
@@ChrisStaecker Well you’re asking something there. The Hamaan Manus ‘R’ must rank very high for ability, but I also rate the Facit CM2-16 for usability. As a modern collectable the Curta is definitely a widely regarded device, if not for its abilities, for the sheer ingenuity of getting it into such a small package. That took real 3-dimensional thinking long before 3D CAD was a thing
I haven't been so disappointed since I bought the latest *Teenage Navigator* album only to realize it was a compilation album with no new material.
