While having a crappy shift at work, I sneakily check CZcams during a break and see a new video from Clickspring. The rest of the shift will now see me being a paragon of calm. Similar to Bill Bailey after he swallowed the little book of calm in black books.
Add a dab of lavender to milk; leave town with an orange, and pretend you're laughing at it.
When you're feeling under pressure, do something different. Roll up your sleeves, or eat an orange.
Now, picture the ocean... AGH! AAGH! Oh, oh, a calm ocean!
K
Clickspring is our book of calm.
If you’re ever wondering “why hasn’t Clickspring released anything in a while?”… it’s because he’s still tapping a chisel into brass for what must feel like all eternity.
@@voltairegoetheI accidentally dropped mine into the ocean somewhere around Greece…maybe one day he’ll make that one too.
Legend has it, he is still tapping away to this day...
Any news about your Antikythera Mechanism model 😎?
i can''t help but picture the guy who designed the machine sitting down with the long-bearded philosopher type who commissioned it, and being told, "well, it's a cycle of 223 months, but then there's this extra 1/3 of a day that complicates things, and then there's the whole thing about eclipses not necessarily being visible if they do happen-anyway, you can do that all with gears, right?"
"uh...."
No doubt there where many uh elements involved in that design - you can go to the best machinists today with CNC, all the historical information, Computer and the internet and CAD and order "an Antikythera mechanism but for today" - "uh" is probably the first response ;)
"Uhhh.. gears?"
@@computeraidedworld1148 Yeah, toothed wheels able to link our human understanding to the very machinations of the heavens themselves. A set of _metal gears!_
Lmao. I would love to have watched that go down
Not too different from what modern engineers deal with. "You can do all that with software, right?" "Uh..."
Grateful to experience these rare events. Take your time ; each episode feels like we witnessed the previous one only moments before. It's suiting that the subject matter is about time, because this endeavour of yours has turned itself into a veritable time machine.
Hear hear I love this I stumbled upon this channel back during episode two of this series and I’ve always been a lover of ancient technology ( everything that is pre industrial revolution) and how it works
Like the that scale of understanding
I’ve lost interest and will probably watch it all at once when it comes out like a Netflix series binge.
@@bertradmacher2623 the reason why I like the pre industrial technology is because of the amount of time and care that was put into the the object most primitive thing that comes to mind is a knaped arrow/spear head and the most advanced would have to be a hand made ossuary with hand blown glass spheres to represent planets
@@brennanlangless8912 ,
Suddenly…
This is honestly some of the coolest stuff ever. Every episode is jaw dropping in its beauty, complexity and…uh…sciencey.
Hehe, i just wrote to my gf about this. First, i admire Chris for his precision and clean work. And his really deep study of this mechanism, inscriptions, work techniques... And then i think that he is doing this work a couple thousands of years after the original. For those people back then, this level of technology and precision would compare to a quantum computing today. Something at the edge of fantasy and reality.
@@ogi22 ...and video editing finesse.
Unintended side-effect of building an antikythera device: now fluent in Ancient Greek.
A brilliant instrument that could only be remade by a brilliant precision machinist, through countless hours of study and painstakingly time consuming precision crafting, using only period tools, specifically made for this project. Sorry, ran out of adjectives, Chris.
Thank you mate :)
Part of me screams in modern anguish at how this could be cnc manufactured (among all the other modern techniques/3d printing).... And in the same breath, that cold replication just wouldn't be the same at all. Doing it 'right' by the inventors and throwing countless hours of masterful work into the creation just seems fitting. Proving that it could be done is walking the talk, and I love every minute of it.
Truly Chris, thank you for sharing (and the immense research on the back end) this re-creation.
@@frollard completely agreed! Part of me cries out to CAD model it then get it machined so I can have a replica of my own. But so so much more of me is content with being able to watch this incredible and caring artisanal craftwork.
@@frollard I completely agree.
@@Clickspring You deserve all praise we can think of - this was an immense undertaking and you pulled it out in perfection 🙂
The patience shown in engraving alone is super human. You are creating a modern priceless artifact.
I was about to say the same thing. This is brilliant work indeed.
Your work and devotion on the science and engineering to understand and bring to life this is truly astonishing! To my humble opinion this is hands down the most accurate but also aesthetically pleasing rendition of the Antikythera mechanism ever made, worthy to be in a museum itself!
Not only am I looking forward to seeing this as a finished, working piece, but the mega edit for it will be great as well.
Chris, it's magnificent! Unfortunately, though, some things never change: after thousands of years, reading an Operating Manual remains a daunting and baffling experience. This one's all Greek to me... 😁
😂
Ektos an ise ellinas...(unless you are Greek!😁)
lmao
... And let us all also express our gratitude for the outstanding effort in scripting, filming and packaging each mind-blowing episode!
Another phenomenal episode of what's easily the most fascinating series on CZcams
I'm not sure if there's a word for "far beyond a work of art". This is a work of exquisite beauty, love, and history all wrapped up into a superb presentation, covered with fantastic commentary, and teaches a phenomenal bit of history. Simply wow.
You left out the words maths and science.
and when the world needed him most, he returned!
Need a click spring mechanism to predict when Chris will make his next episode in the series.
@@Slipperypotato365 Only Old Tony's lathe truly knows such secrets lol
The National Archaeological Museum of Athens, which houses the original remains, should consider shelling out a really big amount (maybe with additional crowdfunding) - to buy this resulting machine, and the tools that were necessary to build it. I would be in the cf campaign with whatever i can afford. Truely breathtaking effort, Chris!!!
Just watched all 12 of these videos, plus the making of the tools, and I have to say these are some of the most beautifully made videos I’ve ever watched. Amazing content!!
Someone give this guy a Nobel Prize.
So true one of a few people on this planet who could have done work like this
This has to be may favourite build series Chris, I’ve watched it so many times as it’s got it all, entertainment, inspiration and ingenuity.
The level of craftsmanship for not just the mechanism itself, but for the camerawork and editing that makes everything both extremely clear and beautiful along with the truly educational explanations really does put this past so much other stuff on this site. Absolutely unreal this content is available for free, I look forward to every episode in this series and never been let down.
Dear God this is complex on so many levels. I am blown away.
the level of precision and ingenuity displayed in this is so incredible. every episode of this series absolutely blows my mind, every time i think it couldn't possibly go deeper it does.
Not gonna lie, but I opened the video and just clicked LIKE without even watching it because, you know, it's gonna be GREAT. It's soothing to listen to his calm voice explain the dazzling intricacies of this delicate mechanism with such aplomb. 10/10
This is at the same time archaeology, craftsmanship, precision machining, math, astronomy, photography, art and time travel.
Thank You Chris for taking us along on the epic voyage
When you have finished, where will your reconstruction end up? It seems to me to be almost as important as the original device. Well done
Unbelievable patients. I can see myself trying to engrave that dial. 3 minutes in, after I make an unwanted scratch, things start flying about the room. Excellent work Chris.
Now there's a lot to absorb here! .....Ya think ? Brilliant as usual.
Absolutely astonishing. Thanks for undertaking the project, and sharing it with your peerless presentation.
As an Engineer find you workmanship beyond belief well done young man this should end up being displayed in a museum
Wow....that is all I can say. What a project done by a real craftsman worthy of the challenge
i am so excited to read the doctoral papers that will come out of your making this.
Maaaaaaaan when this thing is finished there'll be a 2 1/2 hour full build video or something like that.
I'll do something fun, for sure - Cheers :)
Damn, surprised to catch the video at 2AM, guess I'll go to sleep later :) thanks for your work Chris
I don't even follow TV shows and yet here I am always watching out for a new ClickSpring episode!
Our world shadowed by nuclear war, this masterpiece brings a little light back. Magnificent Clickspring.
Really love the look of the black background and the brass symbols showing thru. Also like that you kept the conjectured text scratched in to give context to the whole thing.
I had almost lost hope of ever seeing an other episode.....It was worth the wait!!
Finally, some of the best workmanship i ever saw! Thank you!
I have seen a couple of documentaries about the mechanism and they both made all sorts of claims comparing it to modern technology. Your explanations are so much clearer and put the technology and craftsmanship in context with it's time.
Наверное вам уже говорили,но у вас "золотые" руки. Вы сами создаёте инструменты которыми потом работаете...просто супер!
I'm vibrating with excitement! My favorite video series I discovered this year!
Lucky you i have been following this series for at least 4 long years.
@@Slipperypotato365
I mentioned this series while teaching class at church in Indiana. I moved to Texas three and a half years ago. Having taken Koinah Greek in college this really brings the geek out in me. Working as a locomotive composite mechanic, I find the engineering in this extraordinary and the execution exquisite.
Oh you don't know how much I needed to see a new Clickspring video today...
That was awesome. It's rare when I find a video that has links that I'll spend even more time on. I am patiently awaiting the completion of this device of antiquity.
I've watched this series since it started 5 years ago, viewing each episode nearly the day it released everytime. To see it in this state is such a satisfying feeling. Extraordinary work Chris and thank you for bringing us all along for this journey! Can't wait to see what your next project entails. Cheers!
So excited to see another episode. This has been my favorite series. The work is incredible.
Great to have you watching mate :)
This series is such important work you're doing, bringing this process to the people. Thank you for giving such a unique view of history!
Uuuuugh thank you for saving a terrible Friday... 😌
Chris, you alone are the reason to start using CZcams. I subscribed years ago when it was brass parts. You continue to up your game to a level that exceeds any expectation. You are one of maybe a handful of humans that understand what you are describing and yet you make acessable to all. Thank you.
The power of language or writing, small symbols that convey greater meaning. And a mechanism that can hold them, convey them and give them context for greater meaning. Rather astounding really.
He blessed us with another episode
I can't imagine the patience and tenacity to precisely hand engrave all those markings.
Yes new Clickspring video, love your craft dude, watching these is like ASMR :) Greetings from Switzerland
I never want this series to end.
I hope the mechanism will be finished, and then will be shown used daily over several years. Just to give us the insight of the use and level of usefulness. Imagine how facinating it will be to see this machine predict astrological happenings!
I literally danced with joy when I saw there was a new Clickspring video. Made my night.
The amount of work that Chris have invested is baffling by itself, the attention to detail and the breakthrough discoveries made, simply humbles me down, I bet, that at he end off all of it, Chris would be the only one with a whole, 100% functional, Antikythera mechanism
I would like to see this mechanism on the museum display where the old, original pieces are being showcased, next to it, as a recognition of such extensive and detailed work
Chris reconstruction is a huge step forward on the knowledge field of such detailed instrument, and will awe the future generations who will like to understand why the people of ancient Greece would have go to such lengths in order to understand their surroundings and the sky above, all in the pursuit of knowledge and bettering the human race
Astonishingly beautiful.
Seeing these videos pop up in my subscriptions is such a gift. Thank you.
I remember when you started the series, and built the vice/tool holder and files.. it feels like yesterday! Thanks for putting the videos together, if you consider CZcams a modern day library of sorts, this is one of the choice collections within.
Hadn't even thought of resetting the dials for perpetual modes, but beyond that I'm speechless Chris! Such a Maestro at all you do!! Hat Tip, slight Nod...Respect! ~PJ
Genuinely never more excited to see a video than to see one of yours in this series. Thank you so much for sharing this incredible project with us in such a sophisticated fashion.
It’s astonishing that, as far as I know, this is the only example we have of what must have been a relatively mature technology in it’s day. It can’t possibly have existed in a vacuum by itself, there must’ve been a whole plethora of related machines and implements that led to its development, whole workshops of craftsmen who were capable of interpreting the plans and creating them, books of celestial observations and treatises on the maths involved, and so on and so forth. And yet, this is all that we are left with. Love your work Chris, keep them coming!
@@asicdathens alternatively, the mechanism was never made by the helenic greeks, but instead was in fact cast through time and lost in the antikythera shipwreck by chris, creating a closed time loop where Chris was inspired to craft the device.
That moment when you're glad you don't ring the bell 🔔 because the happiness of being surprised is better than a push notification. Love this series 🤩
Yay Chris! I was so worried that there wasn't going to be another installment, when I got that bell and here it is! Thank you for the single-most interesting series of videos I have ever seen!
The amount of work on the detail never ceases to amaze me.
After convincing myself I would have thrown the pointer arms across the shop the first time I got ham handed with a file and broke the spoke off of it. Then he goes to hand engraving what musta taken years worth of glyphs.
Patience of a saint. I really was impressed by your clock build and now have to wonder if This Old Tony taking you to the future has something to do with all of this.
Great work Chris!!!
Yes, another episode! This is an amazing mood lifter on a moody friday night. Thank you so very much for your hard work Chris.
I feel like it might be nerve-wracking to ship the device without damaging it, but it would be incredible if it could go on tour at various museums around the world. I'd do anything I could to go see this in person once it's complete. Wherever it ends up though, I want to try to see it. Thank you for working so hard to preserve this knowledge.
And just imagine what it was like shipping the first one! And then finding out that it was lost at sea....
@@BrooksMoses one could only laugh before for crying.
@@BrooksMoses I was gonna say. Worst that can happen is that it ends up at the bottom of the sea. Nothing we haven't dealt with before...!
@@BrooksMoses That's the final step of the build. Truly preserving the history by dropping it in the ocean. It has to be historically accurate!
Been watching this series for a couple years now. Very exciting to see it finally complete.
This is by far the best channel on YT. Thanks for sharing your work with us.
Thank you Chris.
This machine is so clearly a labour of love for you, as it no doubt was for the ancient craftsmen who made the original.
I'm sure they would approve of you skills!
Tonight just became a good night
Most of this went completely over my head but watching this man work is soothing.
I first found your channel when you were making an amazing clock years ago, little did I know what an amazing journey your skills and passion would take you on. Thank you for taking all of us on this wonderful trip with you thus far. And I and many others look forward to what the future holds.
Stunned following this series. Worthy of a Doctorate in several fields
we need a new one!!
Agree! More on the way as soon as I am able - Cheers :)
It's not just the mathematics involved but the precision of what you do that is astonishing to me.
I'm in awe of your craftsmanship.
Hey clickspring! Long time follower of this project can’t wait to watch this video!!
It's amazing to see this all come together. When I first heard of the mechanism about 30 years ago, I never dreamt it would be understood let alone see someone build it. Bravo.
Welcome Back
Perfect Timing
The Thought process behind this machine boggles my mind. So much Respect for your steady hand.
Thank you 😊
The man has done it again. Beautiful work brother.
I am amazed people back in the day were able to figure this out.
Even better: it's not like we figured it out ourselves.
It was people "back in the day" who figured out all of this, and we learned it all from them.
I just saw the real thing today in a museum in Athens and was absolutely blown away. Then was told about this channel.. absolutely love the insight and details on the device and look forward to the next time seeing the display and understanding it a bit more. ♡♡♡
Made my day to see this pop up.
This has been my favorite series of any others. You have an amazing way of story telling, and you work is outstanding. I learn just by watching your mastery in action. Good show!
OMG Chris! I’ve just been re-running through all your Antikythera videos… thanks so much for this latest instalment. So much amazing work dude.
Mate you have two things that makes a great machinist, patience and attention to detail. Keep Being Awesome.
By far one of my favorite pieces of content on the whole platform. This is simply exquisite and beautiful.
NEW CLICKSPRING VIDEO???? YOU ALREADY KNOW I AM DROPPING EVERYTHING TO WATCH IT!!!
Processing the complexities and multiple levels of qualifiers for every data point of this is giving me flashbacks to having to learn lowest-bidder custom enterprise software for my job.
I have quite enjoyed this recreation over the years! Thank you, sir!
I finally got the opportunity to see the original mechanism myself when living in Greece for a month.
I'm always floored by the quality of these videos. The builds are gorgeous, the explanations are detailed, and the editing is astounding. Your work has always been amazing and every time I see a new video from you, it's something special since I know great care has been put into making it. Thank you for your hard work!
Hot damn, when you realize how much you've missed these videos over the last few years. Please take all the time it needs, I understand it's ready when it's ready... But know it's akin to an endorphin rush to hear your voice in a full feature video again! Cheers mate.
I suppose it's not necessary to engrave the bits that don't survive. It won't impact the bootstrap paradox you and Tony created.
"Bootstrap paradox"???
@@lancer525 I believe the commenter is implying that the mechanism made here is the actual antikythera and it will be sent back in time.
@@lancer525 I believe they're referencing a collaboration video on this old tony's channel called "ORIGINS" that features sending a modified version of the antikythera mechanism back in time.
@@userPrehistoricman i was going to make a very similar comment myself, its so well made its almost believable that this is exactly what happened. Dr Who would be impressed.
Just breathtaking! Every new episode I feel transported. Keep up the great work!
I’ve loved watching this mechanism come together since you started. Watching the dials move together for the first time gave me chills
You make us understand the level of patience that was required from the original builder of that mechanism to precisely engrave all the detailed informations without a single error. Now I understand why we didn't find more samples of that amazing device.
And your own level of patience to understand, copy all those details on the replica and explain it to us is also impressive.
Instant like, will watch when I get home this arv! Thanks
The hours that goes into engraving that much text with a tiny chisel and a hammer must be... overwhelming..
wow man, this is utterly mind blowing. its just amazing to realize people did this so long ago. its crazy. thanks man
I am speechless. The complexity is far beyond my expectations. The mind that created it in antiquity was an epic genius. The greatest loss is his identity. With the exception of only one, in the time frame. Exceptional video, Chris.
