"'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
@@thewolfin
They bear repeating.
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"
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.
Laughed out loud at “have you heard of Clickspring”
Love this channel and Clickspring.
Me too!
“It’s not perfect, but it’s me.”….
That is what makes it perfect.
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.
Yeah, I was gonna recommend running it across a stamp pad a few times to load it up.
Sundays with Uri - perfect day
"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"
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
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 ^^
I love the perfect fit of the frame inside the two rails and how smoothly it glides over the wooden surface. Wonderful reconstruction
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.
@@chrissibersky4617 It's a tractrix.
Finding a house broken and trained mathematician is hard these days; they’re all running wild and feral on the prairies.
the homage to clickspring was genius! haha
"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.
I don’t know why it’s taking me so long to say this but here it goes. You are by far my favorite UA-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
Acoustic horns following this tractix contour have smoothest impedance matching! It is a beautiful curve indeed.
Nicely done!
Whoever built this in the 17th century must have used approximately the same tools and techniques.
Uri is asked to build some beautiful doohickey thing and at the end is like "hm, so that's what it does."
Extremely entertaining to watch an old world craftsman. Truly a Renaissance man in every sense…
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"
You just KNOW there was 1 dude who watches your videos in that museum staff, who suggested Uri Tuchman immediately when they got the chance
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"... :)
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.
This intro almost sounds like an alien pretending to be human writing a memoir.
Yes, or AI
Oh it _does_
I live in Brest !! Can’t wait to see your beautiful piece of art.
Beautiful work, as usual.
Your sense of "ha ha" is always appreciated, as well.
“A long time ago on a cold winter night after a long summer day”
Me: oh this is gonna be good.
Can't wait for the Uri Tuchman "Antikythera mechanism done right" series.
Uri Tuchman deserves to be preserved for posterity
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.
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. 😁
The uncrowned king of brass Uri always a pleasure to see you tinker. 👍
Of course I like the video. Watching you make things out of wood and brass makes my day.
Finally he returns. So much to love, as ever.
I love the caption at 4:59 and at 7:37
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.
Those are the prettiest wing nuts I have ever seen. Seriously. Lovely AND functional!
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.
Most excellent. Thank You Uri Tuchman.
Fantastic Uri. I really enjoyed seeing you create this piece.
Uri, I love your ability to make complicated machines with simple hand tools. And that you don't take yourself too seriously! Thanks
Same
Thanks for another great video Uri. And as always, looking forward to the next one. Cheers from Norway.
Thank you Uri! Wonderful craftsmanship here. Great video. Hilarious opener.
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
Bro your picture will be in a museum one day.
How nice to see someone using proper brass drill!
I'm glad you agreed to make this !!
Great to see you making things again
You just made my day. A long time ago, on a cold WINTERS night after a long SUMMERS day......I suppose Europe does have funny weather
Thank you, just beautiful.
Thank you, Uri.
I like the new workshop Uri. You should be able to produce some wonderful things now !!
Amazing craftsmanship, a pleasure to watch. Many thanks wonderful Video
you are really a underappreciated youtuber
A beautiful machine. So they ONLY wanted 'Uri Tuchman level accuracy'? Fortunate they bumped into you when they did 😉
Always a Pleasure Uri.
thank you .👍🏻
Good to see you back in action Uri 💪🏻
Cool project. All that hand work is amazing.
Great to see you working in your new shop! :)
God bless useing Gods gift and sharing it. Its great to see great work and to feel good after watching. Thank you
Perfect, Uri, perfect.
Intro was godly, i LOL'ed few times! Espeacialy in shadow part.
Uri, Your work is truly exquisite. The craftsmanship is simply wonderful. Do not under estimate how good you are. Your work is breath-taking.
Nice work. You are a Modern-day Master Craftsman
you made a great ingenious, eeeh thing .
that line is really amazing...
thank you mr. Tuchman it was a pleasure as always....
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 best part of your work is just being done manually and small parts with a machine, and that's what values and differentiates your projects, very good to watch.
Awesome work! Given the way this mechanism work, I'm pretty sure it's designed to draw a “simple” asymptotic function (pretty sure it's 1/x) depending on the angle you start off at different points of the function's curve and the difference of the carriage to the swiveling center scales the size of the drawn function.
Thank sir, I was waiting since long time for your video.
A small hole for a lead to make the mark on the paper seems necessary. Congratulations on the interesting commission Uri.✌
I think that looks wonderful!
The Clickspring comment was great!
Thanks for sharing 🇨🇦
Great video Uri. I love your new shop.
Fantastic job on this project
I ❤️ed it!!! Great story too. You should start all your videos like that!!💪🏼❤️🙏🏻🤣🤣
One fine morning in the middle of the night...! Gorgeous contraption!
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.
Beautiful work
Couldn't figure out what I was missing until your videos were put up. Thank you, URI.
“That looks horrible, but it looks pretty good” is my new life motto.
Not the sort of video I would normally watch. However WOW you are a very talented guy and the device works and looks beautiful too
A reconstruction of a line drawing thingamajig. Probably the best line drawing thingamajig on UA-cam... for now. 🧡
Oh god he was using a wing divider to hold the rivets. Truly the work of a master craftsman 😂
Love this channel. Keep it up Uri
This is a delightful video! 👍
I love it. ❤️
Thank you.
What an exciting project!!
Beautiful. I love your humor. It's good to see you working in your new shop. Congratulations 🎉👏
Thanks for another finely crafted mechanism done with wit and humility.
Wonderful video, yet again
your level of detail and use of mostly hand tools to create your creations is truly amazing!
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..😆
Beautiful work!
Even your toilet seat is made of brass, I put money on that!
Be bloody cold in the winter
Amazing work and skill. Well done
Truly only a master craftsman and artist could create something that beautiful. Bravo URI you're the best!
Beautiful.
Excellent skills.
✨👽✨
I see by the rubbish on the floor that your new shop is treating you well. Great video as always sir.
He's having a collaboration with HTR on the rubbish project.
fantastic Uri, a great video.
