A Clock That Runs for 10,000 Years

ScuttleMonkey posted more than 9 years ago | from the that-is-quite-a-marathon dept.

Technology 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.'"

The clock requires maintenance (1, Informative)

Anonymous Coward | more than 9 years ago | (#13825419)

The article i slashdotted, but if it's the clock I am thinking of, they made it deliberately so it requires regular winding (not sure how often). That is, it's not a "set it and forget it" type thing.

http://en.wikipedia.org/wiki/Clock_of_the_Long_Now [wikipedia.org]

the article seems slashdotted.

Seems a bit silly to me for them to require that, given that we as a species get bored of things .. the should account for that. I suppose if someone finds the clock after 10,000 years they'll be able to crank it up .. that should be awesome to do. It should be placed in a hollow large chamber of obvious intelligent design, so that if the place is ever buried .. a future archaeologist will be able to detect it and recognize that it's not a natural cavity etc. Also I hope we're around and it's not the descendant of a mutant penguin who ends up cranking it back up rather than a human.

The timekeeping mechanism is self winding, but the display requires winding. The idea is that it will keep time regardless, but someone (or something) is required to read it, so "reward" them for being there by updating the display.

Still, no mechanical clock, however cleverly crafted, can keep perfect time for 10,000 years. So Hillis added solar synchronization: A sunbeam striking a precisely angled lens at noon triggers a reset by heating, expanding, and buckling a captive band of metal.

Star field accurate? Why no modern tech.? (-1, Troll)

Anonymous Coward | more than 9 years ago | (#13825537)

Why doesnt the clock have an LCD display? It seems like they used lame tech. Sure they demonstrate some knowledge of analog mechanical computing ability .. but this ability has been around since the forties .. before the space age. We want humans of the future to know that we understood that the stars themselves are moving (ie, certain stars would no longer have the same relative positions in the sky ..example: Barnard's star is moving at 10.3 arcseconds per year against the background. We want to show we have that knowledge .. also the textures of the planets in the model including that of Saturn, triton, Mars etc. should be as detailed as possible. Evidence that we sent probes there. The moon should have a marking where Neil Armstrong landed. Heck even include a copy of Wikipedia on HD DVD in a simplified binary format without any complicated enoding scheme. Ok that may be a bit extreme. But I think that minimally the design of the clock should demonstrate the peak of the builder's knowledge and aspect of culture (ie, the use of the LCD display even though mechanical may be more easily understood). There is no reason we can't have both a mechanical display and an LCD display.

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.

Actually, the current NIST atomic clock is accurate to 1 second in 60 million years, which somewhat trumps the one in the article. There's nothing this one can do that the atomic clock and a good computer couldn't do a lot better. What's special is that it manages to do all this mechanically, and with a degree of accuracy beyond most mechanical clocks.

Re:enough? (1)

vidnet (580068) | more than 9 years ago | (#13825499)

While the mechanicality is the greatest feature (the article mentions maintainability for any future civilisation, and insight into inner workings without disassembly), the clock isn't comparable to atomic clocks in that it keeps astronomical time, similar to UT1 [wikipedia.org] . Atomic clocks can only keep the equivalent of UTC (or more fitting, GPS time).

Of course, many slashdotters would probably value atomic time over astronomical time, but that's besides the point :P

Re:enough? (3, Insightful)

bpowell423 (208542) | more than 9 years ago | (#13825624)

The thing that most impresses me about this clock is that it will run by itself with no required interaction for 10,000 years. It requires no external power, no attention at all. It is self-winding (he mentions barometric pressure change as a power source). As far as accuracy goes, it synchronizes to the sun when sunlight through a peep-hole heats a bimetal strip. That should re-sync the time every sunny day, so it should be accurate until it quits working. Imagine a future, several thousand years from now... maybe there's been another "dark ages" and people are just rediscovering bits of technology. Some explorer notices this cave in the side of this mountain, climbs up there, and discovers this massive clock. That's what this guy is after. He's trying to create something on the scale of a "wonder of the world" that will exist (and continue running) for millenia and cause future generations to marvel at the technology that these ancient people had.

Sure, an atomic clock is more accurate, and more useful, but it requires electricity, and I'm sure some attention to keep things running smoothly.

Although, I wonder if this mechanical clock will need to be lubricated every now and again... 5000 years from now there'll probably be some wierd religion where the priest pours holy oil over the sacred time keeper, or some such...

Re:enough? (1)

polysylabic psudonym (820466) | more than 9 years ago | (#13825595)

The clock is intended to last. Not to be perfectly accurate. It improves its accuracy sufficiently to probably keep on the right day for 10 kiloyears by reseting itself every midday using a mirror and warmth from the overhead sun.

Well his earlier prototypes were so I'd assume so:

"Hillis is in the process of rolling out these and more ideas in a series of increasingly complex prototypes. The first one, now on permanent display at the Science Museum in London, was financed by an anonymous donor who lent it to the museum. "The deal we offer is, if you fund the next stage of the development of the clock, we will give you a prototype," says Hillis. "We have spent millions of dollars so far--I don't know the exact number."

"The nine-foot-tall London clock uses a slowly rotating torsional pendulum, ticks once every 30 seconds, and tracks hours, sidereal and solar years, centuries, phases of the moon, and the zodiac--and happens to be hauntingly beautiful. Incredibly, its three-year-long construction was completed in a mad rush scarcely one hour before midnight on December 31, 1999. That meant there was no time to test it before the switch to the year 2000, the most complex date change in the Gregorian system since the year 1600 because it involved a once-in-400-years leap year exemption."

8tim8 (623968) | more than 9 years ago | (#13825413)

Isn't the whole concept of time a human-centered activity, meaning that concepts relating to time change over time? The clock might be able to tick off the seconds over 10,000 years, but will it be able to reset itself when the switch date of Daylight Savings Time (in the US) changes in a year or so? What about future changes of that sort? TFA is actually pretty fascinating but it sounds like the inventor paid much more attention to engineering problems than to human factors relating to the concept of time.

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!

Re:Great, does it have an alarm? (1)

Flaming Babies (904475) | more than 9 years ago | (#13825546)

The "Dual Alarm" allows a time for radio and a separate time for the buzzer.

Each supports: Every Day, M-F or Sat-Sun and the RADIO alarm lets you set the station to play
when it comes on, which can be different than the station played for 90/60/30/15/ minutes
with a different volume setting.

Turning the alarms on and off is easy (just press the Radio or Buzzer buttom - each time it
turns on or off the alarm). Push and hold the radio or buzzer button to set the alarm time
for the alarm in question (radio or buzzer).

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!).

Since the current season of BSG has ended the answer to that question is yes so you need not bother to wonder.

fantomas (94850) | more than 9 years ago | (#13825565)

indeedy - read the long now website - they are aware that for it to last 10,000 years it will need to be woven into the social/ ritual fabric of culture.

As you rightly point out, it just takes one group of people to trash it, hey in the UK lots of people got upset about the Taleban blowing up the Buddha statues in Afghanistan, but then remembered we also destroyed most of our own religious heritage through a series of political /religious fundamentalist purges - Richard Lionheart [wikipedia.org] (lets sell gold and relics to fund the war and pay for freeing the king) Henry VIII and the dissolution of the monastries [wikipedia.org] (I'm going to start my own flavour of Christianity so I can marry again, this gold will do nicely), and Puritanism [wikipedia.org] (destroy the evil Catholic relics). Seems like humans do a pretty good job of trashing their long term histories every few years :-)

MikeHunt69 (695265) | more than 9 years ago | (#13825528)

The most complicated portable watch ever made is the Patek Philippe Calibre 89 [fortunecity.com] pocket watch. Although it doesn't keep track of the wobble of the earth, it does keep track of things like sunrise/sunset, the position of the stars, moon phases, leap year, etc.

I don't know the price but since their wristwatches start at around USD$8,000 and go up to over $200k, I suspect you could buy a very nice car for the price. Patek make rolex look like cheap crap (which is mostly true).

hywel_ap_ieuan (892599) | more than 9 years ago | (#13825530)

What a beautiful concept. It reminds me of the kinds of things that I sometimes come across in fantasy and sci-fi stories. They don't have to be integral to the plot, but they illustrate the world the author has conceived - think of the statues at the Falls of Rauros in LoTR.

The references in other comments to atomic clocks miss the point entirely. Atomic clocks are about precision and accuracy. This clock is concerned with accuracy, but only at long scales. A mechanism to re-set to local noon, as described in the article, is plenty to catch the daily drift and would probably compensate for running fast/slow for many days if the sky were cloudy. For the kind of astronomical time this clock is concerned with, being a few seconds behind or ahead is irrelevant.

I believe that this is the same clock that was mentioned by Time a few weeks ago in an article on Danny Hillis, the co-founder of Applied Minds [appliedminds.com] .

These guys are geniuses, the kind you see in movies. Danny Hillis himself thought up the idea of parallel processing for his doctaral thesis while he was a grad student. They don't specialize in any fields, they apply their creativity to R&Ds in almost any field, be it medical, defence or engineering.

They are the ones who created that voicebox [prnewswire.com] which replies incomprehensible snippets of your voice to prevent eavesdropping, a human-size Dino [wikipedia.org] robot walking around Hong Kong Disneyland that can mingle with the tourist without any danger because it is able to shift its weight such that if its foot encounters an eggshell, it can back off without breaking it. (that's in the middle of a step) and the company also created a tabletop display that can show a 3D view of any location on earth by using thousands of pins to replicate the actual reliefs.

standards (461431) | more than 9 years ago | (#13825615)

This clock is designed to be more of a monument than a useful timepiece - something that will help people understand their short time on earth, versus a science instrument.

However the engineering effort to make this clock as accurate and as long-lasting as promised is truly impressive. Few things built today are designed to last that long (exception: perhaps long-term nuclear waste storage?) The materials : stone, steel, tungsten - and the size of the parts, and the mechanics of the thing that allows for 10,000 years of wear, along with easy maintenance - man, these are not things that even your top-notch mechanical engineer does.

Interestingly enough, this guy is working on a long term clock, while others can't even get little clocks to work right. Some public clocks [blogspot.com] can be grossly imprecise. It's funny how someone running a time service can't get their own time right. Hopefully the telcos will hook up their time services to this clock - or NTP services. Whichever is easier.

How do you win at tic-tac-toe? (1)

From TFA:

``As an MIT undergrad in 1975, Hillis and his friends built a binary computer out of 10,000 Tinkertoy pieces. It could beat all comers at tic-tac-toe.''

Okay, I _must_ know this secret --- I've taught my kids to play, and while I can still beat my son (age 5), my daughter and I _always_ wind up with a tie. I even saw a movie once where this nifty supercomputer called Joshua couldn't win a game....


firmware upgrades will be needed (1)

tota (139982) | more than 9 years ago | (#13825626)

Whenever someone decides to add another leap day (every 400 years or something) or take one out (every ~2000)

or when a disaster has a big enough impact to make the earth wobble (tsunami 2004 anyone?)

How do you upgrade your watch?

Materials (0)

Anonymous Coward | more than 9 years ago | (#13825632)

It's almost a footnote in TFA, but it seems like the materials questions pose the greatest obsticles here. The clock is largely mechanical in it's action. So this would involve building a mechanical system that needs to run smoothly (read: without stiction ANYWHERE in the main stack) for 10,000 years. Obviously, anything that will corrode is probably not the best idea. Not only that, but the parts need NOT to bend under their own weight in 10,000 years--no way to seal out gravity. Finally, since there are a lot of moving pieces, this needs somehow to be lubricated in such a way that 10,000 years of dust and grit can't clog the mechanism. Even if you seal the mechanism in some kind of dustproof inert gas chamber, now you've got to ensure your seal holds for 10,000 years...

This is an interesting concept, but it seems like there's a LOT of cleverness that needs to come out in the choice of materials if this is going to go from something that in theory could possibly run for 10,000 years to something that we'd actually EXPECT to have run for 10,000 years.

Cesium? (1)

pvera (250260) | more than 9 years ago | (#13825649)

Is this more precise than a Cesium atomic clock? When it comes down to it, all the leap calculations, etc. are programmatic and are not related to super-accurate timekeeping. What you really want is a really stable timing signal, which is pretty much what you get out of a Cesium atomic clock.

I don't know if this is done in the civilian industry, but back in my military satellite communication days, we used to keep no less than two Cesium clocks on site at all time. These produced insanely accurate 10 MHZ and 1 Pulse per second signals which were then distributed to all our other electronics equipment in-house. All our up/down converters, multiplexers, modems, etc. relied on this centralized clock. If one of the clocks got out of sync we were not even allowed to fix it ourselves, instead these were shipped over to the US Naval Observatory, which was in charge of dealing with these.

FishandChips (695645) | more than 9 years ago | (#13825672)

I guess that clocks are literally "future proof" since they can only tell the time today, right now. Bit of a limitation really.

Maybe some billionaire will end up with it. Good luck to the makers! But I suspect the builders of Stonehenge might have scoffed a little. Their clock is still going and it has no moving parts.
