"'Can you make this mechanism?' they asked. I started laughing
'Accurately,' they continued. I stopped laughing."
"Have you heard of Clickspring?"
Yes these were lines in the video thank you for transcribing them
I came, I snorted laughter, I stayed for the whole video.
Gold statement by Uri
You know you're a master artisan when people can ask you to do museum level reconstructions, and you can do it flawlessly, without actually knowing what it does beyond make lines lmao. Seriously though great work and glad you are getting the renown you deserve
Thank you my friend!
So what does it do??
"the mathematical universe... which is ...
...the actual universe"
Best line!
I agree, right up there with "Have you heard of Clickspring?" Haha
Yes,I agree.. and in a long Winternight after a long Summerday
I see, you have fun to work with materiel like this. That's great.👍
the universe neither knows of or cares about maths, it's a tool invented by man to incompletely describe and model some aspects of it.
@@axeman2638 ok grandpa
"Get me Clickspring! Wait, he takes how long to finish a project? Damn, if only there were some kind of.. Budget Clickspring".
*Uri Tuchman bursts through the wall, into the wrong room*
Lmao. Isn't he hilarious
The main differense is that Uri could achieve the same things without any of all those expensive machining tools.
(And The machines he are using fit's the theme very well, i realy love the old late for example.)
@@sheep1ewe That seems a little unfair on Clickspring. He certainly has the machine tools and knows how to use them, but given that he also not only hand files gears but makes the files for it, it's certainly not that he "couldn't" do it without the machine tools.
@@fnordfnordsson4385 Yes, maybe my joke was a bit too far, i hawe the deepest respect for Cris and i watch every single video he made public.
Antikythera year 5... "This year we make the worlds not perfect screw by hand filing a 40kg block of forged steel down to a 2mm screw"
I’m pretty sure you’re supposed to stain the wheel thingie with ink, that’s why it’s removable.
That makes sense. Good catch.
Laughed out loud at “have you heard of Clickspring”
Love this channel and Clickspring.
Sundays with Uri - perfect day
I live literally 20min away of this museum, already visited it 3 times and its really cool ! I'm pretty excited to go see your builds when they will be on display ^^
“It’s not perfect, but it’s me.”….
That is what makes it perfect.
I love the perfect fit of the frame inside the two rails and how smoothly it glides over the wooden surface. Wonderful reconstruction
"Have you heard of Clickspring?"
I chortled.
We all chortled.
I laughed
Some of us guffawed.
I sniggered
I giggled. It made me doubt my masculinity, but there it is.
A beautiful reconstruction Uri. Now if we only had a tame mathematician... Oh wait! Matt Parker or Hannah Fry would be able to explain this.
If he made it not quite accurately but very nice looking, would that be a Parker Curve?
I think this is the curve where if you drop a ball on each side they connect in the middle regardless where on the curve you drop them and even if you drop them from different heights.
It probably has a name but I can't remember.
the homage to clickspring was genius! haha
I don’t know why it’s taking me so long to say this but here it goes. You are by far my favorite TH-cam channel. PS I love you.
He's definitely one of my favorites as well. I love the goofiness, makes him real and not pretending to be someone else.
We all make mistakes. it’s when we learn from them, thats what matters the most, not the mistakes themselves.
😳
My channel is built on mistakes!!
I think it's because you typed "I don’t know why it’s taking me so long to say this but here it goes". That's why it took so long
Uri, I love your ability to make complicated machines with simple hand tools. And that you don't take yourself too seriously! Thanks
Same
"Have you heard of clickspring"
"We have but we are short on time and funds"
"Say no more I Wil build you a stunning beautiful and accurate-ish reconstruction"
Great build! No idea why mathematicians would get all googly over drawing a curve, but if they're happy with it....
I think its the "golden ratio"
@@jonpierce8342 they want to draw eyebrows?
@studer1679 no, I have a feeling the next one will be a tractrix. This one is a logarithm, Im not sure but I have a feeling choosing the length determines the base of the log you draw. They were used to solve equations graphically.
The mechanism somewhat dupcates the Logrithmic or Exponental curve which have a unique relationship betwenn X and Y which no other method of free hand drawing or tracing can duplicate. It may sound irrelevant now, however consider the time in which it was designed. No one had ever seen a true Log or Exponential curve at this point, they were approximated however no accurate representation was ever demonstrated. We take a lot for granted in our digital time, just look at a slide rule demonstration video. It is likely that anye reading this has a parent, grandparent, or relative that had to use them in school/life
"In 1728 the Italian scholar Poleni took up the theme again. He designed a tractional instrument (see Plate 10 [this mechanism]) and sent copies of it to three colleagues. In his covering letter he argued, again, that by means of his instrument the problem of the *quadrature [area] of the hyperbola* was now for the first time solved in a geometrically acceptable manner" www.gewina.nl/journals/tractrix/bos89.pdf
It seems the context of this device is the ancient topic of Euclidean geometry, about whether things can be constructed with the most basic physical tools, (straightedge and compass) rather than by arithmetic. These devices construct transcendental curves without arithmetic, but they're still not a straightedge and compass, so some 18th century controversy perhaps. Or as that article so nearly puts it, "The motif of tractional motion as mechanical legitimation of transcendental curves"
One of the best video intro's i've heard :D
"on a cold winter night, after a long summer day"... "have you heard of Clickspring?", LOL
Reminds me of my love of Vaucanson’s lathe in the Paris arts and sciences museum. 1751 first lathe to feature angled ways and solid frame. I hope to eventually visit and see it in person. The video from Machine Learning called ‘The Machine that made everything’ is amazing.
Oh that was a great video, I come back to see it every now and then
I believe you meant "Machine Thinking"... :)
This intro almost sounds like an alien pretending to be human writing a memoir.
Yes, or AI
Oh it _does_
Uri is asked to build some beautiful doohickey thing and at the end is like "hm, so that's what it does."
I live in Brest !! Can’t wait to see your beautiful piece of art.
Couldn't figure out what I was missing until your videos were put up. Thank you, URI.
The most impressive thing about Uri is that he compresses days, weeks of work even, down to 14 minutes and has yet to cut his ear off.
“A long time ago on a cold winter night after a long summer day”
Me: oh this is gonna be good.
Beautiful work, as usual.
Your sense of "ha ha" is always appreciated, as well.
Whenever I watch you work, I have to resist the urge to buy brass and engrave something.
Then do it
@@andyb7963 I did it! I found a Buck 110 with brass bolsters and i did some terrible engraving with a dremel, but i did it. 😁
It's always a pleasure to watch you work Uri! Keep up the great work and may you continue to hone your skills as a master craftsman for many years to come.
Uri Tuchman deserves to be preserved for posterity
One fine morning in the middle of the night...! Gorgeous contraption!
Those are the prettiest wing nuts I have ever seen. Seriously. Lovely AND functional!
Poleni was a venitian mathemathician, astronomer, physicist,... genious. This contraption is to draw a logarithmic curve.
That's what I was looking for
What is that?
@@timsmith1589 it is a curve representing a logarithmic progression, reverse of an exponential progression.
Finally he returns. So much to love, as ever.
Absolutely beautiful Uri.
At first I thought the device was an overly elaborate method of tracing one quadrant of an ellipse. I'm glad I read the paper now. It is in fact a logarithmic curve. Fascinating.
Oh, and that intro was captivating, and just too funny. Thanks.
Was wondering wich one it was. Thanks.
Great intro -raised a few smiles.
Your videos always delight Uri. I listened to a podcaster interviewing you a few years back and have ended up listening a few more times and sharing with sons- both subscribers - as well as some friends. You're, without doubt, one of the most interesting and talented people on TH-cam.
your level of detail and use of mostly hand tools to create your creations is truly amazing!
Fantastic Uri. I really enjoyed seeing you create this piece.
Great video Uri. I love your new shop.
I am learning a lot from your videos, and this video may well be the most useful I've watched on your channel so far. Thanks, Uri. Amazing work.
Beautiful work as always, Uri. Thanks for the video!
I love your videos so much, your creativity, humour, passion for oldies make it perfect for me !
I'm very glad your talent is recognized my friend !
Cheers from France :)
The uncrowned king of brass Uri always a pleasure to see you tinker. 👍
Most excellent. Thank You Uri Tuchman.
I love your "projects" and look forward to each new one like a child waiting anxiously to get his hands on a new toy. You are in a class all your own. One of the most talented persons I have ever seen. I thought I was a most talented fabricator leaning on 60 years of learning and making "things" with my hands. But I bow before you. I am but a tinkerer in comparison. Your hands and mind have been blessed and yet you are most humble and simple. God bless you and thank you for sharing with us all.
Beautiful, very nice job as always.
Love this channel. Keep it up Uri
Beautiful. I love your humor. It's good to see you working in your new shop. Congratulations 🎉👏
Thank you, Uri.
Thanks for another great video Uri. And as always, looking forward to the next one. Cheers from Norway.
Perfect, Uri, perfect.
Thank you, just beautiful.
Thank you Uri! Wonderful craftsmanship here. Great video. Hilarious opener.
Oh, how I have missed you! Glad to see you are well and creating content! Thank you, Uri!
Your workshop is beautiful it is so organized and tidy. This machine is very interesting.You made this difficult build look easy.Thank you for the video
Amazing craftsmanship, a pleasure to watch. Many thanks wonderful Video
Always a Pleasure Uri.
thank you .👍🏻
More beautiful machines, thank you for sharing your work.
Amazing device you made there! Really amazing craftsmanship - and quite a lot of effort - the result is a really elegant piece of equipment as always! Thank you for sharing this!
Fantastic job on this project
Great to see you working in your new shop! :)
Beautiful work
you made a great ingenious, eeeh thing .
that line is really amazing...
thank you mr. Tuchman it was a pleasure as always....
Wonderful job and great that your work is now in a museum!
Great to see you making things again
Beautiful work!
Man this just continues to impress. Thank you so much!
Cool project. All that hand work is amazing.
Oh! How ingenious! And your rendition of it looks pretty classy in my opinion! I enjoy seeing your craftsmanship.
fantastic Uri, a great video.
Of course I like the video. Watching you make things out of wood and brass makes my day.
Amazing work and skill. Well done
Gorgeous work. thank you for all the effort.
I love the new shop. Keep doing this awesome work. Greetings from Brazil!
TA-DA!!! Beautiful! Great work Uri and if I ever get to that museum I'll look for it!
Uri, Your work is truly exquisite. The craftsmanship is simply wonderful. Do not under estimate how good you are. Your work is breath-taking.
What a absolute pleasure it is to watch a craftsman at his work. Just beautI fully and detailed work. U are a true craftsman and artist. Thanku so much for sharing your amazing talent..😆
A beautiful machine. So they ONLY wanted 'Uri Tuchman level accuracy'? Fortunate they bumped into you when they did 😉
That is a beautiful piece made by a marvellous craftsman. Thank you for your videos, you are a true inspiration.
Wonderful video, yet again
Nicely done!
Whoever built this in the 17th century must have used approximately the same tools and techniques.
Amazing work love to see your creations
Loved the video, thanks for sharing!
As always incredibly inspiring and skilful work. Thanks for sharing and, as far as I know, being you.
Thanks for another finely crafted mechanism done with wit and humility.
You are one of a kind, and I loved the video! What an honor to make a museum piece!
I was glad to see your lathe in use. I will be building one similar to it at some point and can't wait to do so.
Thanks for the wonderful video, and all those to come!
Good to see you back in action Uri 💪🏻
Truly only a master craftsman and artist could create something that beautiful. Bravo URI you're the best!
Exquisite work, as always.
Amazing work.
This is a delightful video! 👍
I love it. ❤️
Thank you.
What an amazing thing to be asked to do! Im so happy for you. Also i love how shinny that is
I like the new workshop Uri. You should be able to produce some wonderful things now !!
Love you videos, thanks for sharing!
Uri, That's is fantastic as always.
Fantastic! I just checked out your website as well, your art is incredible. This is my first time seeing your videos, and won't be the last. I appreciate the time you put into the absurd, it fills my heart. Thank you.
Thank sir, I was waiting since long time for your video.
Amazing job.
Congratulations! I'm not surprised that the museum came to you. Looking forward to the next one.
Very beautifully executed, Mr Tuchman 👍
I love this, as always it is a great joy to see your talented work unfold. 😍🤗👍
