One of the early ideas for the 10,000 Year Clock was to simply endow a family whose job it would be for 400 generations to just shout out the time every day.  I had no idea there was already someone like that… RIP John Votta.

“The Washington Square timekeeper was a link back to a very ancient tradition of people who both tell time and look out for the public good,”

YES Watch Father’s Day Sale

Long Now’s 10,000 Year Clock will tell time not in hours and minutes, but by keeping track of the astronomical cycles underlying those units. We can’t predict how the calendar and timing systems will change over the next 10,000 years, but we know they’re likely to be built on top of the very same things we’ve built our system on: the rotation of the earth, the cycles of the moon, and the ebb and flow of light and dark throughout the years’ seasons. For most of human history, time wasn’t  a matter of digits ticking by, but rather a complex interplay of these overlapping rhythms.

The makers of YES watches seem to similarly appreciate this long-view of time-keeping. Into thoroughly modern digital timepieces with all the standard functionality you’d expect in a digital watch, they’ve incorporated a taste of our deep history with the sky. YES watches feature an analogue hour hand that rotates once each day, indicating along its way the rising and setting of the sun and moon.

It’s because of this resonance that we’ve carried them for years now in our Museum & Store in San Francisco, but between now and Father’s Day, Yes is also giving Long Now a 20% commission on each watch bought online through this link: For Father’s Day, they’ve created a new style of watch with two 24-hour bezels.

Bjorn Kartomten is the brains behind this innovative design. He worked with a global team of manufacturers to realize his idea of making a watch that tells modern time along side the cycles of the sun and moon. The hand movement is made in Switzerland, the sapphire crystal in Germany and the chip is made in Japan. The Yes Watches are used by film directors, photographers, adventurers and more – anyone who would like to to have an accurate understanding of the day and night’s natural cycles.

Time in the 10,000-Year Clock

Keeping time for 10,000 years isn’t tricky just because its hard to build a really durable clock. It also forces us to recognize and account for changes in things we normally think of as immutable, like the length of a day.

Long Now co-founder and lead designer of the 10,000-Year Clock, Danny Hillis, published a paper recently along with Rob Seaman, Steve Allen, and Jon Giorgini, with the American Astronomical Society.  The paper discusses the different kinds of time that the Clock needs to track in order to show accurate time for the next ten millennia, and how these systems interrelate.

The 10,000-Year Clock has both a pendulum (generating an approximation of absolute time) and is also synchronized to the sun at noon. Therefore the Clock must reconcile Universal Time, Terrestrial Time, and Barycentric Dynamical Time and also deal with unpredictable changes in the Earth’s rotation:

“The variation is caused by a variety of effects including tidal drags, shifts in the Earth’s crust, changes in ocean levels, and even weather… This creates an uncertainty in the average length of day of about 10 parts per million, an uncertainty of plus or minus 37 solar days over the design lifetime of the clock.”

So, not accounting for these variations could theoretically leave the Clock over a month off at the end of 10,000 years. Read the paper to see how each system is accounted for.

The paper was presented at a colloquium in October 02011 called Decoupling Civil Timekeeping from Earth Rotation. Attendees, including astrophysicist Neil deGrasse Tyson, discussed the paper and the 10,000-Year Clock. Notes taken during the conversation show that, while the technical success of the Clock’s durability is yet to be determined, its ability to inspire long-term thinking is already taking hold:

Neil deGrasse Tyson jested that the Long Now should put some signage on the 10,000 Year Clock so that a post-apocalyptic Earth will not think that the world will end when the clock stops working.

Clock Project Update from Jeff Bezos

Below is the Clock Project update by Jeff Bezos published at

Quick Update and Video of the Raise Bore Milestone

We just completed the 12½ foot diameter, 500 foot deep vertical shaft for the 10,000 Year Clock. We used a mining technique called raise boring. Take a look at the video – it’s an interesting operation. Instead of drilling down from the top, you pull a large diameter reamer up to the surface from the bottom using a smaller diameter pilot hole – more efficient than a top-down drill because the rubble isn’t fighting gravity. It rains down beneath the advancing bore and gets hauled out a horizontal shaft at the bottom. Our next major step will be cutting the spiral stairway using a robotic stone cutting saw. In parallel, we’re also manufacturing and testing the Clock components.

The Clock team continues to do an impressive and amazing job – they are organized and ingenious. Extra special thanks to Danny Hillis and Alexander Rose who deserve big kudos for driving to this key milestone. Big thanks as well to Swaggart Brothers, Cementation, and Geomagic, all of which played a crucial role. I encourage and invite you to become a member of The Long Now Foundation, the non-profit that was founded to foster long-term thinking and has focused tremendous energy on the Clock, as well as other noteworthy projects. You can visit their website to learn more and become a member.

Many thanks for your interest in the Clock and in the long view!

Through the Wormhole with Morgan Freeman is a show on Discovery’s Science Channel that features cosmological and metaphysical questions about science and the universe.

Mr. Freeman, as it turns out, is quite the geek.

An  episode from the show’s second season recently asked, “Can We Live Forever?” Well known scientists such as Michio Kaku and Aubrey de Grey provided perspective on the challenges and research underlying the the science of human life extension. (Coincidentally, a newly announced DARPA research initiative on the subject, called Biochronicity, was mentioned on Long Views just last month.)

Also featured in the discussion was Long Now Executive Director Alexander Rose. You can see a clip of his segment below:

Inside Svalbard, the Doomsday Vault Saving the Past and Future of Agriculture

Posted on Monday, July 25th, 02011 by Alexander Rose - Twitter: @zander

The Svalbard Global Seed Vault is an underground repository located at 78 degrees North latitude that currently stores nearly a million seed samples to preserve crop diversity for the future. Many see the vault as a resource for a “doomsday” scenario brought on by severe climate change or other ecological disaster. Long Now has been following the Svalbard vault closely since it was first announced over a decade ago. In 02011, Long Now Executive Director Alexander Rose had the opportunity to visit Svalbard with unprecedented access to the vault through a partnership with the Center for Land Use Interpretation (CLUI).

Rose’s account of the trip follows below, and includes an update on the recent surge in public interest surrounding Svalbard over the past year.

Svalbard February 02011, (most photos, video and sound recordings by Steve Rowell)

The Planning:

Over the last couple years artist Steve Rowell has been planning a project to document the Svalbard Global Seed Vault as part of a larger project about the beginnings and future of agriculture.  The Seed Vault is designed with a 1000 year design life to store back-up samples of every food crop seed in the world.  About a year ago Rowell contacted me to see if Long Now would be interested in participating in his project.  I said that we would as long as I got to come along on one of the trips to Svalbard and meet the creators of the Vault.  The Norwegian government management of the vault required that Rowell also get participation from Scandinavian nations, specifically Norway as part of his project.  Over the last year he was able to secure funding and collaboration with a Norwegian and a Dutch artist, and with it an official invite to visit the Vault.  Long Now would cover our accommodations for this scouting trip, and I would cover my own flight.  The Seed Vault administrators seem to be a bit overwhelmed with the interest in the Vault.  They open the Vault about twice a year to deposit new seed stock and they are apparently inundated with requests to visit.  However the remoteness of the location and their limited time on site means they really don’t have time to give many tours.   But with persistence and the Scandinavian participation Steve was able to secure us the invite.  We quickly booked our complicated flights, and found accommodation in one of the few places to stay in winter.

The Journey:
On February 22nd I boarded a Lufthansa jet bound for Munich out of San Francisco.  I would be meeting Steve in Oslo the following evening as he was traveling from Washington DC.  It took three tries to fly out of Munich due to aircraft difficulties that resulted in me arriving at 1:30 am in Oslo.  After a couple hours of sleep I met Steve the next morning at the airport hotel breakfast area, and we boarded our SAS flight to Tromsø at the northern tip of Norway.  It was a rare clear day, and I was able to see the stunning fjords of Norway as we crossed the 66th Latitude into the Arctic circle.


In Tromsø we were asked to exit the plane and go through an ID check.  I think it has something to do with the unique treaty status of the Spitsbergen Archipelago where Svalbard is.  The Spitsbergen Treaty, ratified almost a century ago, gives Norway sovereignty over the area, but they have to grant completely equal access, immigration, and commercialization to any signing nation with minimal taxation.  This also means that there are a number of refugees on the island, and I suspect they want to keep track of them.

We re-boarded in Tromsø to find the plane completely packed.  Aside from its major coal mining activity and arctic scientific research, Svalbard is a winter tourist destination to see the northern lights and wildlife.  Crammed onto the plane were Swedish grandmothers, Russian coal miners, scientists and even a couple babies.  Everyone had shed the usually fashionable northern European winter-wear for serious expedition wear.  Huge gore-tex parkas with fur lined hoods and patches reading “Antarctic Survey 1996” abounded.  We landed in 30 mph crosswinds and driving snow.  The pilot was clearly used to the airport bringing the plane down fast, but touching down without even a bump.  We caught the local bus to our accommodation – Mary-Ann’s Polarrigg, and even glimpsed the Seed Vault perched just above the airport.

The town of Longyear was founded by an American from Massachusetts of the same name.  He bought the rights to a coal deposit from a Norwegian company and established one of the first permanent outposts on the island.  With the coming of the airport in the 70’s, Longyearbyen changed from a tiny mining town to a University town and adventure tourism destination.  I will not recount the history of Svalbard in any detail, it is well recorded by many sources including Wikipedia.  I do recommend The Future History of the Arctic by Emmerson for anyone interested in the bizarre and increasingly consequential future, present and past of the Arctic region.


Mary-Ann’s Polarrigg (entry shown above) known locally as “The Rigg” is a long row of prefab buildings from various eras, mostly leftover from the mining industry.  Mary-Ann the proprietor is an amazingly sweet lady who has filled the place with the wildest and weirdest eclectica to be found on Svalbard.  Stuffed polar bears and arctic foxes mingle with old mining equipment and incredible historic photos.  She is also the chef, preparing hearty Nordic breakfasts and dinners of local seal, trout, reindeer and of course… whale. (In Norway they have t-shirts with a picture of a whale and the tag line “Smart food for smart people”.

Our first two bone-chilling days on the island we spent touring around in a borrowed car from Mary-Ann as our appointment at the Vault was not until our third day.  There are only a few miles of road there, the longest runs of which service the airport and the coal mines.  We got a tour of the Polar University where every student is taught arctic survival and how to use a rifle.  Everyone on Svalbard is required to own a gun, and be trained in its use, for protection from polar bears.  Svalbard is the first place I have ever seen 20 year old students walking in and out of school with rifles slung over their shoulders.

There is a strange basic irony about Svalbard that we discovered on the University tour.  One of the main research topics and political focuses on the island is climate change and atmospheric pollutants.  While the Norwegian mainland gets all its electricity from clean hydro-electric power, the only coal fired power plant in Norway is actually on Svalbard.  But without this coal power, the island would have to evacuate in less than 48 hours.  On Svalbard coal equals life.

The Seed Vault:
Sunday was the scheduled day to visit the Vault, and that morning it was a white out blizzard.  We had been told that not even the Royalty of Norway were allowed in the actual seed vault, and to expect to only see the entry hallway.  Our guide at the University, a few days before, was shocked that we would even be allowed to see the hallway.  The drive up the switchbacks was a bit perilous in the snowstorm.  We had to stop multiple times as visibility dropped to zero.  We met our hosts Roland von Bothmar and Anders Nilsson of NordGen at the top of the road, and together approached the vault.  Apparently they had spent a lot of time the previous day cracking and melting ice off the door as it had been above freezing allowing water to run down, and then freezing the door shut as the evening temperatures dropped. (Note that there is a lot value to a design that sheds water away from hinges, seems, and especially locks.)  Their work had paid off though as they were able to open the door quickly and we all scrambled in out of the nearly horizontal snow stinging our faces.


The 320 feet of fluorescent lit down sloping entry hallway is separated into three equal sections.  This first section we enter into from the outside door is not completely sealed off from the outside air.  You can see where the permafrost meets the building in a sloping line of hoarfrost built up on the wall.  We move deeper toward the next door.  Roland asks us to watch out for the ice on the floor, apparently the freeze thaw cycle melts the frost on the walls which then runs down the floor and then freezes again, making the ramp treacherous.


On the other side of the door the hallway widens to a 20 foot diameter corrugated metal tube with a concrete floor.  Roland explains that this part of the vault has been shifting as the permafrost around us thaws and freezes.  Indeed the concrete on one side of the floor is cracking as evidence of this.  The wall at the end of this section is a new addition and is still covered in a tyvek like building wrap.


Once through this next doorway the floor curiously transitions to asphalt, possibly to allow more flexibility and water permeability.  There is a pump system and grating newly installed in the floor to deal with the water from the thawing frost.   All of these water and freeze-thaw issues have been discovered since the vault was finished in 02008. The walls and ceiling of this section are about 25 feet wide and tall.  The very rough surface is a product of the drilling and blasting into the loose local shist.  The rock has been stabilized with large bolts roughly every 4′, covered in shot-crete, and then a white paint.  This wall, ceiling and floor finish is the same for the rest of the vault, including the seed chambers.  This hallway terminates in a large concrete wall with a metal door in it, and there are a few other doors on the right hand side at the end of the hall.  Above are cable racks and the ever present ventilation tubes.  One set of the tubes has frost building up on each joint section, these are the cooling pipes for the seed vault bringing them down from today’s ambient -5C to the desired -18C.  We enter the doors on the right into a control room.  This area has desks and a PC and a sign in book.  The list of people who have signed in is impressive,  Everyone from UN president Ban Ki-moon to President Jimmy Carter, and… us.  I had assumed this was as far as we were going to get, but then Roland says that he is turning the lights on in the next section for us, and warns that camera lenses brought into the colder areas will fog up.  We leave a selection of lenses here, and pass through the third lock. (Sound recording in the last hallway section)


Through the doors the asphalt starts sloping back upward and we enter into a lateral access hall where you can see each of the three seed vault doors.  The doors are embedded in concrete walls blocking off each rough blasted chamber.  The central chamber, vault 2, is covered in a thick layer of frost, cracked away around the door from the recent depositing of this years seed stock.  The cooling pipes above are fully covered in thick frost here as well.  The only adornment in the whole space is a spear-like metal shape on the wall, a seed sculpture by a Japanese artist who donates these pieces to seed banks all over the world.

There is a shelf here with some plastic bins and seed samples of the types found in the vault.  Glass jars, vials and bags each containing labeled seeds from different seed banks around the world.  Now they use a standardized mylar zip lock bag and plastic bin.  However Roland points out the USDA submissions always use their own box, a cardboard one.  It turns out that this seed vault is the second one on Svalbard.  There was one created in the 01980s for just Scandinavian species which is inside a shipping container in one of the old coal mines.  It was sealed 30 years ago and Roland hasn’t even been there.  Roland explains that all the seeds arrive by cargo plane a week ahead of each deposit, upon arrival they use the airport x-ray machine to make sure there are only seeds being deposited (e.g. no bombs).  In the last 3 years since the vault opened they now have over 637,000 varieties in the vault, and they have not even filled up one chamber yet.  Roland also confirms what we learned from the University, that all the seeds here are edible crop seeds with one exception.  Through a partnership with the University at Svalbard they have stored about 60 varieties of plants from the Spitsbergen Archipelago, none of which are edible.


Roland also mentioned all the crackpot theories and stories people have about the vault – like the one where it is really all the big bio-tech companies trying to control the world food supply. These of course are not true in the least. It is a Norwegian government project run by a consortium of academic, government and non-profit scientific entities. The seeds remain the property of each donating country, and the manifest is public (you can go to the website and download it now if you like). Depositors can pull their seeds at anytime for any reason. So far no company has submitted GMO seeds, likely because of how much disclosure they would have to do around them as part of the process.  The really interesting question though is what happens if a country ceases to be a country, who then owns the seeds and the rights to access them? (Sound recording in the transverse tunnel)

Roland opens one of the empty vaults for us.  We shuffle into the air lock area and after the outer door is closed, the next door is opened.  This vault, number three, has no seeds or cooling system.  It is about 100 feet deep and 30 feet wide and tall.  Some of the same shelving used in the active vault is in here, along with the plastic bins ready for more seeds to be delivered.  Amazingly the thick stone wall shared with the active vault two is covered in frost.  Wires dangle from sensor equipment on each wall, and there is one spot you can see the fractured native shist where the shot-crete doesn’t quite meet the floor.  We also go into the other empty vault, number one, and it is similar, except it is completely empty.  We ask if the spaces were sterilized or treated in any way before the seeds go in.  Roland says that they are not, and that the mylar bags and the cold are all the seeds need.


Then to our surprise, Roland offers to open the active vault.  Jimmy Carter wasn’t even allowed into that vault.   We crowd close to the ice covered door, we need to let as little cold air out as possible.  Roland unlocks the door with one of only four keys in the world, and we hear the frost crack at the hinges.


We rush into the airlock, and the next door is opened.  This vault is COLD.  The difference between -5c and -18c (0F) is palpable.  The inside of my nostrils hurts and the skin on my face tightens.  Most of the space near the door is taken up by the cooling equipment.  Apparently this equipment was installed just 6 months ago to replace the original equipment that was less efficient, loud and blustery.  Ten feet in front of us is a locked gate, and ten feet beyond that are the shelves and shelves of boxes.  Each box is marked with the logo of a seed bank from a different nation, the USDA cardboard boxes are front and center in the second row of shelves.  We are allowed a few photos and video and are ushered quickly back out again.


After the visit I read some of the material we received.  It doesn’t go too much into the “why” of things, just what happened in the building process.  But what was apparent was that they had a very tight deadline, and I am not sure why.  Most of the decisions, location, contractors, and material choices were made solely for this expediency.  While it will likely be okay if people are there to maintain it, it seems some of the issues like the shist rock site, ferrous metal reinforced concrete, permafrost shifting and flooding, may require a lot of intervention to maintain the integrity of the vault.

I certainly learned a lot being here.  Mainly that even if you put your site in the hardest to reach place in the world, people will still want to come and visit it – in droves.  They did not design it for visiting, and are having to deal with this fact now.

We ended the day with a dinner up at Huset, the most northerly restaurant with a Michelin star.  We ate scallops and reindeer with Roland and Anders as well as a seed scientist from University of Arizona who was in town to deposit their collection of desert legume seeds from around the world.  What an amazing day.

Other Travel Notes:
Our last day here we finally got an opening in the weather.  We arranged a guided “skooter” (snowmobile) tour and our original plan was to visit the Russian coal outpost of Barentsburg, but after talking to some folks we switched it over to Temple Fjord.  I cannot recommend touring Svalbard this way enough.  We even saw the direct sun for the first time since our arrival when out on the fjord.  Be prepared for cold unlike anything you have ever experienced. Under the thick “skooter suit,” boots and helmet loaned to me by the guide I wore: expedition weight base layers, a complete down suit, a fleece, two pairs of thick socks, a neck gator and a balaclava.  I still got chilled to the point of numbness.  Any small chink in your armor, and the wind augmented by 50km/hr on the scooter cuts right to your bones.  We encountered a dutch two masted sail boat that purposefully traps itself in the sea ice each year there.  They operate it as a kind of outback adventure hotel.  Do not miss touring these outer areas, they are spectacular.


Some notes about clothing.  The Norwegian tradition of removing your “outside shoes” is honored almost everywhere on Svalbard.  Bring snow boots that are easily removable, and carry some slippers or flip flops around with you so you don’t end up in your socks everywhere.  The other pro-tip is to bring a pair of ski goggles with clear lenses (not dark tinted as you wont be able to see).  Even if you are walking 500 yards, you will be glad you did in a snow storm.  As you might expect bring lots of down, fleece and gore-tex layers.  Neck gators, balaclavas, mittens and glove liners are also a must.  It can rain, snow, blow 40 mph, and then turn to sunshine all within an hour.  Headlamp and even a little red flashing jogging light is also a great idea for walking around after dark (eg. after 3pm).


There are some excellent eating and drinking establishments on Svalbard.  The Michelin starred Huset up high in the valley is astonishingly good, (but pricey) and includes a wine list of over 1100 titles.  Also the pub in town next to the market has one of the largest single malt whiskey collections in all of Europe, not to be missed.  You should also stop by the Svalbard Museum, it has won several well earned exhibit design awards.  Likely one of the most interesting and informative small museums I have ever been to.


A general note that if coming in winter (which I do recommend) that you put at least a day or two of float in your schedule.  While you can do most things even in the worst weather here, it seems a bit silly to tour the fjords when you have 20 feet of visibility.  Also note that there are 4 months of the year where there it basically as dark as night.  We had plenty of indirect light on our trip at the end of February.


Living and travel costs in Scandinavia are expensive, but Svalbard is even more so.  Pretty much everything aside from water, reindeer, and polar bears has to be imported by air to Svalbard.  A personal pizza and drink can easily run $20-30, a simple dinner for two and a couple beers can come in well over a $100.  Simple accommodations even in the slow season are hard to book and expect to pay over $150-300/night.  The Polarrigg was nice as they have a full kitchen for guest use, and Mary-Anne let us use her vehicle several times at no charge.  There is a Radisson which is very central, a huge benefit as its a very short walk to most local services (you can walk from the Rig as well but it’s about 1/4 mile in often bad weather).  The funny thing though is some things cost less than on the mainland because of the unique tax status of Svalbard.  Alcohol is much cheaper here, basically US prices.


Like many Scandinavian and northern areas where alcoholism is rampant, the state controls the liquor stores here.  However Svalbard has the most control I have ever seen.  There is one liquor store, and each citizen’s purchases are allocated and recorded.  In addition visitors must present their plane ticket on which they write what you have bought to be sure you do not go above your personal allocation while there.  You can fly in with liquor though…


An Update (August 02017)

Public interest in Svalbard has surged recent months. An incident from October 02016, in which the entrance to the “fail-safe” vault was breached by water brought on by unseasonably warm weather, passed with little notice at the time, but went viral in May 02017 as it became apparent that the United States would pull out of the Paris climate agreement.

“Suddenly the tidings from Svalbard were everywhere, in multiple languages, with headlines like ‘World’s ‘Doomsday’ Seed Vault Has Been Breached by Climate Change,’” wrote Mallia Wollen of The New York Times in a photo essay published last month profiling Svalbard and other “doomsday vaults”that are “racing to preserve a natural order that is fast disappearing” in the epoch of the Anthropocene.

It didn’t matter that the flood happened seven months earlier, or that the seeds remained safe and dry. We had just lived through the third consecutive year of the highest global temperatures on record and the lowest levels of Arctic ice; vast swaths of permafrost were melting; scientists had recently announced that some 60 percent of primate species were threatened with extinction. All these facts felt like signposts to an increasingly hopeless future for the planet. And now, here was a minifable suggesting that our attempts to preserve even mere traces of the bounty around us might fall apart, too.

Outlets such as the Washington Post followed with articles that attempted to calm the hysteria, with headlines like “Don’t Panic: Humanity’s ‘Doomsday’ Seed Vault is Probably Still Safe.” As Alexander Rose notes in his trip report above, scientists have known about the water-and-freeze thaw issues at Svalbard since it opened in 02008. Cary Fowler, one of the creators of the vault, told Popular Science that “the tunnel was never meant to be watertight at the front, because we didn’t think we would need that. What happens is, in the summer the permafrost melts, and some water comes in, and when it comes in, it freezes. It doesn’t typically go very far.” Fowler followed with an interview on NPR’s Fresh Air last month. While he didn’t discuss the breach, he explored many of the “conspiracy theories” and public misperceptions surrounding the vault.

  • Cary Fowler’s book, Seeds On Ice, was published in September 02016.

Clock site in Texas

The Long Now Foundation has started excavations for our first 10,000 Year Clock in west Texas.

Though the date of completion of the 10,000 Year Clock has not been set, and it is still many years into the future, we’re very pleased to let you know that you can now sign up on our waiting list to visit the Clock!

Long Now Members will have priority to visit the Clock when it is completed and should check the Visit the Clock box in the Notifications tab in Member Settings when signed in as a member on the Long Now website.  We will also continue to post project updates on the members only Clock Blog.

Jeff Bezos’ team at Amazon have also created a new website at with information for the public about the project as well as a public sign up page for learning about the eventual visiting opportunities there.

We’ve also updated the Clock section of our website; you can read Kevin Kelly’s new piece on the 10,000 Year Clock project, with diagrams of how the Clock will work.

Long Now remains committed to developing our site in Nevada as a 10,000 year installation in parallel with The 10,000 Year Clock in Texas.

All of us at Long Now who are working on the Clock project, the Board, Clock team and Foundation staff are very excited to see the work of the last two decades coming to fruition.  Thank you all for your support.

The Lego Antikythera Mechanism

Posted on Thursday, December 9th, 02010 by Simone Davalos

The Antikythera Mechanism, pulled from the depths of a 1st or 2nd century wreck off the coast of the Greek island of Antikythera, is the oldest known complex scientific calculator. From the moment it was discovered it baffled scientists and historians who wonders what the provenance and purpose of such a machine could have been, especially since a machine of that complexity didn’t enter into the historical record for another thousand years.

Hypotheses abounded: it was an orrery, it was a navigational device, it was a method of contact with extraterrestrial beings that left it as a gift for the human race. It has only been over the last fifty years that any headway at all on what the device did has been made, and, to the great disappointment of the alien conspiracists, what it actually does is probably way cooler for such an ancient culture than anything the aliens might have left.

The machine tracks complicated interactions between heavenly bodies, such as eclipses, and does it all with gears and cams and a healthy helping of deep-fried awesome. Sound familiar?

These guys have taken interest in the mechanism to a beautiful, meticulous extreme, and have constructed one out of Lego.

Here is a time lapse of how the video was made, which is just as neat as the actual video:

The Clock of the Long Now is right up there in elegance of design with the Antikythera mechanism, although of course this author is biased. The Greeks, however, have the sheer engineering bad-ass advantage, as they made their machine without PTC Pro Engineer.

For more information about the history of and research on the Antikythera Mechanism, please see the very fine Antikythera Mechanism Research Project, a multi-national collaboration of scientists and historians, which drops mad science from a huge variety of fields.
