Congratulations on finishing the research for this! What a wonderful honor it must be :) I'm curious, have you and the authors of this paper been in contact with the previous scholars (Tony Freeth, Derek de Solla Price, etc.) at all? If not, do you know if they've commented about the new analysis? As always, thank you for your great effort.

It's quite amazing that a YouTube home machine shop clock making project could lead to this. Absolutely awesome, Chris.

CommanderTomalak

You can be incredibly proud about this. You have contributed something that has been overlooked for one hundred years. You are a proper scientist now :D I am a scientist myself, albeit in a whole different field, and I do understand very well that going through the rigorous process of getting your findings actually approved and published is extremely time consuming and frustrating at times. Congrats for putting up with it and succeeding! I am now very happy to hear that the building will continue and I am looking forward to upcoming videos!

Soooo glad to see you back. Your first series (Skeleton clock) was awesome. This one is even better. Good to hear the research continues as well. Good for you. Can't wait for the next one because I'm learning so much about close tolerance machining (I'm an aerospace welder) and I've been fascinated by it for a long time.

Very much looking forward to seeing build videos again! This research may not have been as immediately engaging to follow for us, but the potential impact of the findings more than make up for that.

Leonard Solomon

Awesome work; you will be in the history books, mate. On a minor note, I love the taper pin attachment that you use for those little brackets. I have been using taper reamers and pins in my own projects for a few years, since I first learned about them from your videos.

Chris, will there be changes to some of the previous build videos because of your findings, or just additions the the build. In other words will there be some gears removed, holes filled. gears teeth changed? Stay safe thanks Ralph

makovette

Exceptionally good work (and most enjoyable video to document it). I agree that putting the discrepancy down to "builder error" in an otherwise remarkably well planned and executed to the highest standard machine is very unlikely. Thanks for defending the unknown creators and builders reputation of the device. One thing that hasn't changed is the makers of the world are quick to take heat and slow to be given proper credit, even after 2 millennia have passed. Cheers!

Clayton Firth

Amazing work Chris. Glad to see the build series back on. Hope that your in good health.

Congrats! It's interesting that it has taken a hobbyist clock maker who wants to build it from the original evidence to discover this discrepancy! Very excited to see the rest of the build. Are you going to try to recreate the missing gearing?

No changes to the existing built components, I took this into account from the beginning once I noticed the discrepency. However it will have significant effects on what happens from here - Cheers :)

Great video as always and a wonderful paper. Great just great .

I loved reading the paper! College statistics was a struggle for me. But like many struggles the result was the retention of sufficient understanding to be able to follow the conversation without the ability to add to it. One question. Did Figure 4. Inter-hole residuals by hole number, not fully render in the frame? Section 6 is missing in the pdf I down loaded. Lastly, am very pleased to have what would be coffee money do far more good! And really hope the health issues are resolving!

Luther

Have you thought about putting all of the information about the build into a book when you're are finish. I think it would be very interesting

Welcome back. Good to see that the magnificent production values are intact. A note after reading the article: Whenever I see a row (or circle) of even graduations considered along with the idea of adjustment, the word that springs to mind is "vernier". Could there have been a series of holes, slightly differently spaced, somewhere in the missing parts of the zodiac or calendar rings?

Gday chris, firstly, glad you finally got your paper published so a big congratulations there, this is really more to do with your skeleton clock build. I’m really keen to have a go at something like the clock but that’s way above my skill level right now, what would you recommend project wise to get started in the right direction? Cheers

Well Done Chris. Its amazing how much of a game changer your research is, and all because you wanted an authentic model of the mechanism.

Thank you Peter - I've not seen anything to suggest that, but its an interesting thought. Certainly there is still much to glean from the wreckage that we do have - Cheers :)

>>49085251

Thank you Iain - I'd suggest make a start on some of the tools that you will eventually need, for example the depthing tool. You might also find that simply diving into the deep end on a clock is not a bad way to start too. It all looks a bit overwhelming at the start, but you can make a start on the bits that are friendlier to begin with, and you'll be amazed at how quickly you start to feel confident about the rest - Cheers :)

O my gosh! I just put the video on our Watch Later list, thinking it was another short. Then I'm quietly scrolling down my Patreon feed and I read this wonderful news! I'm so excited! I think we'll rewatch episodes 1 through 9 first, do a recap. Looking forward to tomorrow! So good to have you back!

Jonathan Crider

Chris, it's good to see you (proverbially speaking)! It is also good to see/hear that you plan to continue on making videos. But it is absolutely fantastic to hear that all of your research and hard work IS actually bearing fruit! And thank you, genuinely, for taking us along for the ride, so to speak; I know I'm not the only one who enjoyed learning a bit about the peer-review process. (And this is where I hit 'Enter' on my keyboard by accident, which is why this post is edited) Anyway, sorry for the rambling. Final thoughts: welcome back, my good man, as the YouTube Makers community was noticeably incomplete without your contributions. That, and we expect sweat-shop-style video production after the New Year; gotta make up for lost videos! :-) (Yes, that last part was meant as a lighthearted joke; humor is subjective, so it likely gave SOMEONE a bit of a chuckle :P )

My heart skipped a beat when I saw this in my feed a few days ago, and now I finally had the time to watch this video in full. I've been following your finding and publication as closely as you've allowed and am continually shocked at both the quality of the information presented and the sophistication of the defense provided. Though not fully understanding the paper's content, everything I do understand strikes me as being of the same quality as both the videos you are infamous for producing and the work they showcase. Thank you for keeping us involved in this process and I'm proud to be a part of this community of support.

Hello Chris, I just returned from your video being publicly unlocked on YouTube (It warms my heart to read all the wholesome comments), when I once again noticed how the CAD model had changed from the version seen in previous videos. Now I am fairly certain that you simply hid some features from the images of the model to keep the focus on the new day pointer, but just to be sure, you still intend to include planetary pointers on the front dial of the mechanism, right? I'm just wondering because those pointers to my understanding are also speculative.

I have a feeling that the Antikythera mechanism (or one of it's siblings) was at least in part a showpiece for the workshop that made it. Like a fully kitted-out all-extras-included car in a showroom these days. Which leads me to think that (at least on some versions of the machine) the sidepanels could be removed very quickly to show off the complex mechanisms inside.

Anonymous

There is one other thing i'm curious about practical use of the device: If i understand correctly, currently the input handle rotates the mechanisms many days for each turn - i can think of many applications (like for day-to-day use when observing planets and/or using the device similar to a modern wall calendar) where each turn of the handle would advance the display one day, preferebly with the handle resting in the bottom position so it doesn't get accidently bumped. Something like "every morning turn the handle once to see todays sky alignment". Is there any possibility that such a gearing was included in the final mechanism?

Drew

That seems possible and there are several ideas about the actual use of the mechanism. Based on no evidence at all, I favor the scientific/educational use. And, for sure, this isn’t the only or first one made.

Jonathan Crider

Also, WOOT! Congratulations on crossing the 6,000 Patrons mark! Fair evidence that quality > quantity, IMO. I must admit, while re-watching the videos for the Byzantine Sundial Calendar series, I have to chuckle a bit when you mention getting the project wrapped up before the, "big one" (eclipse) of 2017. In my opinion, one can never fault someone for setting high expectations of themselves, even when those expectations aren't met. I mean, hell, you've probably helped to advance human understanding of how time was kept by ancient civilizations! God only knows what other possibilities or lines of thinking you'll unlock. And, to be as clear as possible, none of this comment is meant to be facetious, in any way. Anyway, apologies for rambling like that. I am genuinely thrilled that all of the hard work you put in to researching to ensure that your Youtube videos are as accurate as possible has revealed a hidden gem. Truely, I hope you have the best of luck navigating peer review, getting published, etc. Best wishes to you and yours, - Jonathan

Hey Chris! What do you use to make the digital 3d models of your parts? Like what you see at the 6:46 point in your Antikythera update. I was thinking about getting into 3d modeling to make parts too.

Dilapidus

Anyone else checking here hourly to see if Santa Chris has something for our stockings this year?

Andrew N Dowden

I can't map the Calendar ring (holes) to 254, using my own .SVG render and overlaying both images (holes b/w, 3 months green). Is it possible there is NO 'later calendar' and the ring is "Civil calendar, with NO intercalary days" - so with 360 holes?

clickspring
>>55832474

Hi Andrew, we determined the most likely division candidates to be 354, and then possibly 360. However the key finding of the paper is that the data do not support the previous long-held assumption of it being 365 divisions. If the calendar has 360 divisions without any intercalary days, then by definition it is not an Egyptian 'civil' calendar, since the 5 epagomenal days are a well established feature of that calendar - Cheers :)
