A Clock That Runs for 10,000 Years 438

Justin Blanton writes "Discover magazine is running an article about a clock designed to run accurately for 10,000 years. It's essentially a "future-proof" clock that blurs the line between art and functionality through advanced engineering. From the article: 'Everything about this clock is deeply unusual. For example, while nearly every mechanical clock made in the last millennium consists of a series of propelled gears, this one uses a stack of mechanical binary computers capable of singling out one moment in 3.65 million days. Like other clocks, this one can track seconds, hours, days, and years. Unlike any other clock, this one is being constructed to keep track of leap centuries, the orbits of the six innermost planets in our solar system, even the ultraslow wobbles of Earth's axis.'"

    Anyone remember how "some" people get/got all worked up about the Mayan Calendar? How it "ends" at, oh I don't remember exactly, but it was supposed to end sometime around 2005 or 2006 I believe...

    So...

    Who's to say that the Mayan Calendar creators simply didn't do the SAME thing these people did? That is to make a Clock/Calendar which is accurate for 'n' number of years into the future.

    There is NOTHING cosmic, or "End-of-the-world-doom-and-gloom" about the Mayan calendar either... It was probably something as simple as some Mayan's decided to make their Calendar last for a LONG DAMN TIME!!!

    It is probably just THAT Simple!

    Just a thought.

    I am surprised by the questions/comments regarding practicality. Whatever happened to doing something neat simply because "you could"?

    With all this fantastic clock technology, where can I get an alarm clock that has technology that wasn't cutting edge in 1969?

    I'd like

    • Ability to set different alarms for Monday-Friday and Sat-Sun
    • Multiple alarms, so I can get up early and my parter can sleep in until the second alarm for her goes off
    • Digital tuning (AM/FM) and volume control
    • Ability to match a station/volume to a function: i.e. go to sleep with quiet AM radio and wake up to loud FM radio


    Clock radios haven't changed at all since I first got one when I was about 5! Someone out there must be able to package up a glorified palm pilot with some big buttons and red led's and make a killing. These days you could put 802.11 in it and get weather/traffic reports on a led ticker ... I'm sure there is a market!

    Yes, we could spend all day talking about the technicalities of the clock, the politicization of human calendars, and what the odds are of the thing not getting blown up by someone who thinks that only Allah Knows What Time It Is, etc... but the whole point of the project is cultural/philoshopical. It (as the finished project is conceived) is a conversation piece designed to make observers actually think past what they're going to have for lunch, and whether or not Battlestar Galactica is a re-run or not tonight.

    By checking the clock to see what time it is, in the context of a 10,000-year swath of time (still a geological/evolutionary blink of an eye), one is at least encouraged to keep that larger context in mind. It's intended to dimish the long-term weight of petty squabbles, perhaps remind people that 10,000 years back we were in an ice age, that sort of thing. Might even make you think about your 401k contribution (or forget about it!).

    From Wikipedia, another great building destroyed by stupidity:

    In 1687 the Parthenon suffered its greatest blow when the Venetians attacked Athens, and the Ottomans fortified the Acropolis and used the Parthenon as a powder magazine. On September 26 a Venetian shell exploded the magazine and the building was partly destroyed.

    I read the article before it was slashdotted. He intends to build the final version of this clock in a limestone cave, half-way up the side of a 10,000 foot cliff. The entrance will look natural enough, especially after several thousand years, but as you go deeper into the cave, you begin to see the workings of the clock. First, the slowest moving things like the zodiac, then years, months, etc, getting to faster moving pieces as you go deeper into the cave. All the way back, you finally get to where the heart of the clock is ticking. This guy is definitely trying to create a "wonder of the world" and it's not hard to imagine an "Indiana Jones" type of event where some future archaeologist rediscovers this thing. The fact that the display freezes until someone else winds it (he mentioned stepping on a plate to wind the display), is genious. Imagine you're this explorer, sweeping away cobwebs to get a closer look at the machine. The display reads sometime in the 23rd century. As you step closer, you step on a plate in the floor that sinks under your weight. The display begins to move and when things settle down, the current date, maybe in the 57th century, is displayed.

    The gold standard for our new design will be: I must be able to operate the clock's basic features when I wake up in the morning, blurry-headed and without my contacts in. This basic problem -- that they're used by sleepy people -- seems to have escaped current makers of alarm clocks.

    One could also make a point for a design where it is hard to stop the alarm when you are not completely awake. This would reduce your risk of just falling asleep again after cancelling the alarm.

    The pyramids are still standing. Stonehenge is too. This clock [longnow.com] is made out of stainless steel and monel, a "nickel-copper alloy" that is known to be corrosion resistant. The final version is expected to be made of the same, plus some bronze and other long-wearing substances. The overall design principles [longnow.com] of the Long Now clocks will make them physically durable, it seems like mechanical longevity is going to be the least of their problems.

    The anthropologic aspect of this project is going to be the most difficult, simply because society is a factor. The rise and fall of civilizations happens much more often than the rise and fall of material objects. We can still recover bronze-age artifacts (circa 5000 years old), and even some from the stone age (anywhere from 8,000 to 30,000 years old), but we have very little information on what the societies were like. Most of what we have is just a guess.

    The good news is that those same design principles that make it physically longstanding address these problems from a sociologic / anthropologic POV also.

    Maintainability - The clock should be maintainable with bronze-age technology

    Maintainability and transparency:
    • Use familiar materials
    • Allow inspection
    • Rehearse motions
    • Make it easy to build spare parts
    • Expect restarts
    • Include the manual

    (emphasis added)

    You might enineer it well enough to measure a wobble of the earth, but to actually package it so it can survive 10.000 years and still have a meaning is not only an engineering feat, it must be an antropology feat as well, to make people long after this understand what it is and leave it in pieces.

    The last part of that sentence indeed summarizes the chief obstacle to longevity of any monument.

    Incidentally, this is not the first time that such a time-scale has been deliberately studied. A while ago the U.S. Dept. of Energy actually commissioned a study into the problem of marking a long-term nuclear waste repository (WIPP in New Mexico, Yucca Mountain if it ever opens) so as to prevent unintentional intrusion and possible spread of contamination.

    Physicist and SF author Gregory Benford was on the team, and his account appears as the first chapter of his book, Deep Time. The book is, it seems, out of print, but still available on Amazon. There is a slightly garbled copy of that chapter [uci.edu] online, minus the cool illustrations of several marker concepts. Some illustrations appear in the excerpted report [vanderbilt.edu] of the WIPP Marker Panel. Fascinating and slightly unsettling stuff.

    small micro-accumulation will occur in the darndest of places. if a chamber is sealed, bugs and critters are sure to get n there, and if some mice bring in a bunch of twigs and gum up the works -- and you have insects with a few centuries of grit in the device -- does it run as smoothly? the crawlspace under my house has loads of activity from little scurrying creatures -- anything that relies on exact tolerances for anything is sure to be gummed up -- its only a mattter of time. :>

    Newgrange [knowth.com] is a megalithic passage tomb, build in the Boyne valley of county Meath, Ireland.

    Carbon 14 dating has placed the age of the site to be 3200 years old, put into perspective that is around 600 years before the pyramids and 1000 years before Stonehenge.

    The passage grave is so constructed so that light reaches the inner chamber of the 1-acre mound during the winter solstice (for three days around the shortest day of the year).

    Oh and the roof still doesn't leak.

    If you're familiar with Irish weather, that's an achievement on its own.

    Much like Stonehenge no one is sure why it was built. (apart from being a grave)
    Could the designers have had similar intensions as this project has?

    Maybe the machine is too complex, too expensive, too ponderous and big and pointless-- but it's such a beautifully human little thing to build that I can't help but love it. Not only that, but it's human in a way that is perhaps unique to modern times. The retrospection-- the self consciousness of a people that have discovered they are a part of *history*-- that's what I appreciate in this machine.

    Have you ever wondered why we don't find time capsules from two thousand years ago with messages for the future? It, apparently, simply didn't occur to anyone that they might be able to, by leaving a durable message, communicate in a one sided way with the future. That the human race now can think "I wonder what people will think of us when we're gone... we'd better let them know what kind of folks we are so they don't get the wrong impression", is a very hopeful sign. It indicates to me an elevation of consciousness-- the kind of consideration for the future that might make it so we don't *need* to build devices explaining our society to a hypothetical post-apocalyptic people.

      Maybe we can make this whole civilization thing sustainable after all. The big concern is, are there enough people like this?

    Oh, I'm sorry... Slashdot, right. "Yes, but does it store phone numbers?

    IIRC it was a small blurb in Scientific American a few years back (perhaps even pre-Y2K) where I first read of the LongNow Clock [longnow.org], and it got me interested in other long-term projects and ideas as well (which there aren't many).

    There's a HUGE time capsule at Oglethorpe University [oglethorpe.edu] called "The Crypt of Civilization". Most time capsules you may have read about are small things about the size of a shoebox meant to be opened 50 to 100 years after they are sealed. The "Crypt" was a (indoor, apparently) swimming pool (emptied of water, of course) loaded up with many artifacts and sealed in 1930, and scheduled to be opened in about 6,000 years.

    Oglethorpe is also the home of The International Time Capsule Society [oglethorpe.edu]. Notable pages on the website are Tips on Building a Time Capsule [oglethorpe.edu] and The Nine Most Wanted Time Capsules [oglethorpe.edu].

    As I discussed on the forum at that site, it would be interesting to couple one or more time capsules to such a clock, to have each capsule be opened at a pre-programmed time.

    Disclaimer: I have no connection to Oglethorpe, just a fan of the site, and the "most prolific" contributor to the site's time capsule forum (three of the six posts).

    The clock is certainly a "Next-Generation" design, bring the very first Y10K-compliant device.

    The last country to use the Julian calendar was Imperial Russia. I'm pretty sure it will use the gregorian.

    Personally, all I can think of when I read that quote is the Gods come back and say, "You FAIL!!!" LOL!!!

    Well, what I didn't mention is that the Mayans thought that this was the fifth attempt - each time the Gods made people from different things (the elements and then flesh and bone, I think) and the first four times said exactly that and scrapped it all to start again. So the outlook isn't good, but it's nice that they thought there was SOME chance of getting it right!

    Ah, people, eh?

    Since the clock is binary, getting "gummed up" wont actually slow the clock down. Even if the parts show signs of wear the binary functions will still work. They even built an auto reset function that uses sunlight to heat a piece of metal when the sun reaches noon for example.

    The article also mentions finding material that will last for 10K years, maybe titanium? they havent decided yet. The functioning prototypes use stainless steel.
  • by khallow ( 566160 ) on Wednesday October 19, 2005 @12:56PM (#13827866)
    They probably won't use titanium. One of the requirements is that the clock not be made of anything valuable enough to make it worth tearing up the clock.

    The Maya believe that time is circular.

    The end and rebirth of the world is not a matter of failure or victory, it's just what happens. Every Long Count (52,000 years), the world is "reborn" - this one comes to an end and another one begins. This date range is actually based on stellar movement, although as I recall there are a lot of amazing "coincidences" about such stellar movement too - the Mayans based it off of planetary positions, as everything in the solar system should be in the same place at two dates exactly 52,000 years apart, but also the Milankovitch (sp?) cycle, the wobble of the Earth's axis, lasts 26,000 years, so two of them is a single Long Count, and IIRC either 26,000 or 52,000 years is also something like the amount of time it takes for the galaxy to rotate once or some such. It's been a while since I researched it but it's all just stellar movement, nothing mystical about it.

    The date is December 21, 2012, by the way. We've got two months and two days until the End Times begin. (Yes yes, I'm crossing mythologies now, so sue me, it's an old hobby).

    Putting it in the desert is fine - there's less humidity so maintenance will not be as bad as putting it near the sea or in a humid city. It's just that hiding it far up some inaccessible gulch defeats the point of the machine. For 99.99999999% of the population, it may as well not exist. Unless of course, it's only being built for the .000000001% then hell and gone is a dandy location.

    There's another drawback you're missing. If civilisation collapses, there isn't going to be a caretaker for projects that only 1 in a 100 million people have seen. Whereas if it's a place where you take your kids so they can see a place that their great^200-grandfolks left them a big hello in the guest book, society as a whole might ensures it survives whatever comes down the pike. My sons' mother descends from the family that built the oldest standing house in the United States. The boys' names are in a guest book waiting for them to come see the house some day and sign the spot in the book that's waiting for them. Chances are they'll do it when they have kids of their own and can put their kid's names into the book. This has been going on since the house was built some 400 years ago. Granted, that's only 4% of 10,000 years, but I suspect that as long as the house endures, so will the tradition. The house endures, not because of the descendants, but because lots of people are interested in old houses and are willing to see to their upkeep.

    The Great Pyramid of Giza is a clock that tells time by the stars. It's about 5,000 years old. It still tells the time, if you know how to read it. We don't really know how to read it. Clearly, the problem is keeping the knowledge of reading it alive. Stonehenge is another example. There are many others, like Chichen Itza, probably Angkor Wat. And therefore probably many others where the device still exists, but we no longer recognize it as a clock, because we don't know how to read it. Why is that so hard for you to understand?

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.

Working...
