Antikythera Mechanism SOLVED !

[@TheWirksworthGunroom]

If the question "how did they do this without a lathe?" gives impossible answers, the logical conclusion is that they did have lathes. If they could make the geared wheels for this then they could make dividing heads to produce whatever geared wheels could be desired. It is (in my view) absurd to think that this was the only scientific machine of its kind in the era. It is simply the only one that has been found.

[@denvan3143]

I can sympathize with the researchers concerning their problem of counting gear teeth. It was my job to occasionally produce 2D computer art from original pen and ink technical illustrations of gear clusters. Determining the major and minor diameters of the gears was simple. But counting the number of gear teeth was problematic when one gear was obscured by another or the original board artist, who traced a photograph “fudged“ some of the details. Did that gear have 62 teeth, 63 or 64? Sometimes it was just trial and error to produce a gear that matched with the original illustration.

[@HappyMathDad]

And we happened to find the only one ever made? Maybe, but seems unlikely.

[@mt-qc2qh]

It's difficult for us to imagine how the ancient scientists could have conceived and built such a mechanism, but apparently they had unparalleled focus without the information overload and distractions we have today (i. e. Internet LOL). They would gaze at the night sky and document their observations for generations. These studies would continue to be enhanced with every succeeding generation. I can see the understanding of the math involved, but I'm dazzled my the mechanical abilities to actually build such a mechanism. Pure genius. What else could they have made?

[@spyral00]

It could be the result of the intelligence of one genius man (Archimedes, maybe). Similar to what Mentats are in Dune, without computers the human mind flourishes to its full potential, something that is forgotten today... That's for the design part. The crafting of it is a major mystery though, without lathes or CNCs, what the hell? Must have taken years and years.

@dongraham4760: "The only way I can think of would be to manufacture mandrels made of iron the correct internal diameter of each tube then to fold and beat thin brass sheet around the mandrel and finally solder the joint . " - I concur. A bit like making the carton tube inside toilet paper rolls. I would use pegs from hard wood instead of iron if you want to solder. The sheet metal from the gear wheels is between 1 and 2 mm thick, so that should work just fine.

Creating something can be as straightforward as “this is the problem and these are the resources we have to solve it”; re-creating something has the additional problem of trying to determine what resources were available and exactly what problem was being solved. For example: it wasn’t known for a number of years the Antikythera mechanism originally displayed the varying speeds of Mercury and the moon; researchers didn’t know those were problem the ancient mathematicians/craftsmen knew about and had solved, so they didn’t know the purpose of some of the gears. And some gears are missing, hallsinscriptions that have been discovered are helping solve the mystery.

So, just how did they make such flat non ferrous material? How, exactly did the make all of the cylinders that moved within each other? At that scale?

Irritated by the statement regarding the ancient’s “mistaken belief” that the planets revolve around the Earth. If the purpose of the device is time-keeping and ocean navigation, it is essential that the positions of the planets be shown in relation to an earth-bound observer. There is simply no practical application for a heliocentric model in this content.

[@Lethgar_Smith]

"There is the question of why did they stop with the Antikythera mechanism? Why didnt they go beyond that?"
Because in ancient times knowledge was power, and access to such power was closely guarded.
if those few who hold rare knowledge should die before passing their knowledge and skills on to enough people, then there is a great risk of knowledge being lost.
This is the source of most of our ancient mysteries of technology. The knowledge to do such things DID exist, just only in the hands of the few. Likely a priestly class that guarded their knowledge from being widely disseminated.

Genius work! A Couple questions . The input knob probably needs to be an indexed crank. especially if inputs a specific amount such as one earth day per crank.
The other. did this need to be put on some kind of tripod with a slope such that it matched the plane of the sun [and planets] such that you could sight along its face and site the planets even if obscured by clouds or topography. Maybe a sighting aperture like a sight.

[@mancamiatipoola]

Yes, one turn on the crank is one Earth day. As for the rest we simply do not know. Nothing of the outer case survived except bits of the front and rear cover. However since it does have two faces, unlike a regular clock, then we can assume that the device was meant to sit upright in a vertical position so one can observe both sides with ease.
I can imagine that there were many practical applications for such a device. Agriculture, astronomy, mathematics even an oracle could make use of it.
What fascinates me is how they made such intricate machined tools. I really think the arians (people from the Age of Aries when it was built) had a form of electricity, advanced machinery and metallurgy industry. As the clock maker said, there was no way he could make the nested tubes without an electric lathe, which makes you wonder what kind of tech the arians had in their day... Fascinating stuff!

[@dennisjohnson6371]

How can they be so sure that the device was a Greek device. Its well known that a lot of tech stuff was taken from Egypt.

[@willsomething5305]

Just so you know, Sergei Ponomarenko took your finished model and dropped it in Greece thousands of years ago and all the scientist types are rebuilding their own model. Check Sergei's camera!!

[@davepowell7168]

10:42 world of wonder, l expect the text to read 'made in Greece', or the makers/owners name. Handle with care ?
It's an instruction manual to inform the user, fascinating artifact.

[@albertswift1490]

The problem is not the machine, but How they did it ...

[@yw1971]

If they could find a 400 years priod, this mean they had acceess to some significant records. Probably the Library of Alexandria. When it burned so that knoledge burned

[@arkangeln910c8]

The dramatic question at the end of this documentary: "why did they stopped at the antichythera mechanism", meaning, why there was nothing further, given the amazing mathematical achievement of modelling the planets´ mouvement with respect to a point on earth? The possible answer is that the amazing brilliant mind (or minds) who conceived this mechanism, might have sunk with the invention into the bottom of the sea. This possibility could explain why the author(s) of this invention did not produce other similar inventions nor had time to publish his (their) work in a book. There is not even evidence that other copies of this mechanism existed, so this one could be unique. Whether he/they were greeks is a mistery, even though the inscription clearly says it was greek spoken. If this mechanism was even older, perhaps it was not of greek origin, but was discovered in Babylon, for instance, during the conquest and expansion of the greek empire by Alexander the Great, and the greek savants reproduced this one, only tragically lost.

If the question "how did they do this without a lathe?" - Lathe1. / (leɪð) / noun. a machine for shaping, boring, facing, or cutting a screw thread in metal, wood, etc,
in which the workpiece is turned about a horizontal axis against a fixed tool.

From which year is this film?

[@amorscientiae]

Just this year.

[@michaelfranklinwhibley2935]

Absolutely this and absolutely that actually actually

[@peterwalls-qf7ii]

What do you mean why did they stop? Do you even know how much it cost in raw materials?
IDk who paid for this , but he was loaded. You think this was the work of one man only?
FEH! How long do you reckon it took to make it, a couple of days? This is the work of years ! Research, trial and error , miscast components, failed moulds, lack of materials, holy days he could not work.
How like a scientist, you assume perfect conditions , disregard all that went wrong and voice foolish questions!
It is a miracle even one was made. We are talking pre-industrial society , not the world you are used to.
Everything made was bespoke. There was no excess energy, for extras.

that is a 25 hour clock where the hour hand is Mercury not the Sun that is why it doesnt align properly if you follow the Sun on 24h

[@ephemerabluetit335]

What is UCL?

[@DL6UK]

To be honest I didn´t know that the mystery of the Antikythera-Mechanism was solved though I have learned about it at school.

[@williamburdon6993]

Its amazing that they saved it.

[@spyral00]

So... why don't we find Greek mechanical clocks and watches everywhere? If they can make this, they can make a clock.

[@55ATA3]

We find so little of the past, if this was one of one that may be because who made it also was lost on the boat..... If it were being sent to Rome or were ever it was going to be sold or given to some one, I would think that the person that made it would be going with it to show how it worked and to receive payment or acknowledgement for their work. Sad that we can only guess at what was or could have been.

[@ryanvogel9610]

Reminds me of the episode of Avatar when they go to the library

[@HavenDee28]

Question and comment.
So how did the AM create motion once the gears were in place? A wind-up key like a toy or watch? A crank?
Of all the vids I've seen on this subject, this has the best explanatory graphics I have ever seen. Thanks for that!

[@steb430]

Watch it again!

[@nicktecky55]

You've clearly not heard of Chris Ramsay, he's a clockmaker. search YT: Clickspring.

[@truthonly7699]

at 12 minutes, how can smart people who study and observe think that all the stars and planets are moving, spinning and hurling through space but we see consistent constilations but the North star does not move at all? The top of the earth is flat and all oceans are flat and at same sea level. Water always finds its level.

[@garyrose9805]

This is a process of people building an accurate dinosaur from a single leg bone.
It’s a demonstration of how creative we can be with a couple of bits of gears to build something there is no evidence anywhere else it existed!

[@wmgthilgen]

The device was found over a hundred year's ago on the bottom of the sea. It was there due to a storm that sunk a ship two thousand plus or minus a few year's prior to it being found. Meaning in part that there were those more than two thousand year's ago, that had knowledge of the cosmos we didn't know until nearly the middle of the 19 century. How was it possible for a society so old to come up with the knowledge that we our selves using the newest and most expensive telescope's we have available today. And there's the actual manufacturing of it. They didn't have the machine's we would be mandated to reproduce it. And in the year's since meaning more than two thousand years. It would seem to be the one and only of it's kind.

There where many.

Cela à l'air de t'ennuyer fortement que des gens il y a 18000 ans aient usinés chaque pièces par de la micro ingénierie ...tu reviens avec ton 19ieme siècle alors que cela te choque que des travaux inimaginables ont déjà été faits 5000 ans avant la naissance du Christ ...pourtant ...le Christ lui-même va bien dit que des choses qui dépassaient l'imagination de beaucoup de gens avaient existés très longtemps avant sa venue sur terre .....// Les Romains étaient ingénieux mais ils n'ont pas été les précurseurs dans les constructions et l'ingénierie...d'autres peuples très longtemps avant eux faisaient des choses des millions de fois plus modernes ...que nous hommes de 2023 avons difficultés a imaginer'..les cataclysmes ont renversés le terres l'eau le réchauffement la fonte des Glaces ont eus raison du niveau des côtes maritimes et beaucoup de lieux ont été engloutis sous la terre a plus de 120m ....car il y a eu 2 Cataclysmes sur la terre (( 2 au minimum))....de temps en temps des archéologues déterrent des artefacts dont ils sont totallement incapables d'expliquer l'origine. Car trop dérangeants... ...le fait de penser qu'il y a eu une autre civilisation ultra moderne avant la nôtre nous ennuie...et nous énerve...

[@freedomforthebrave]

So in the 2000s we need x-ray machines to see inside it and the German guy back then with nothing knew more about it then we do today how does that work then

[@larrysnowdon7212]

This the supreme conspiracy! Who the hell made this. No one knows .

[@Amanda-cd6dm]

I knew it was his face found in that ship wreck. The statue

[@trevorkoonce5497]

To question whether a part could be made without a lathe when you ate holding a complicated piece of genius in your hands that probably predates the flood? This question makes you look and sound ignorant in which you are in your beliefs!

[@CottonInDerTube]

I dont even ... damn voodoo.

[@Degenhardt450]

It is amazing. The amount of time and effort calculation is gone into this mechanism all based on a theory that is wrong.😂

[@emmanuelfiolakis9297]

I still believe that there are people that are capable to see what will happen in the future!

[@HappyMathDad]

Here is a video of a lathe made by two metal pins and a bow. I'm sure this method could be adapted to make those tubes. On occasion we give ourselves too much credit.
