Ask Slashdot: Permanent Preservation of Human Knowledge?

Soulskill posted 1 year,27 days | from the you-mean-facebook-won't-survive-the-apocalypse? dept.

Data Storage 277

Wayne2 writes "While there have been many attempts to preserve human knowledge in electronic format, it occurred to me that these attempts all assume that human civilization remains more or less intact. Given humanity's history of growth and collapse with knowledge repeatedly gained then lost, has anyone considered a more permanent solution? I realize that this could be very difficult and/or expensive depending on how long we want to preserve the information and what assumptions we make regarding posterity's ability to access it. Alternatively, are we, as a species, willing to start over if we experience a catastrophe, pandemic, etc. of significant magnitude on a global scale that derails our progress and sends us back to the dark ages or worse?"

Z00L00K (682162) | 1 year,27 days | (#44181773)

Most of the information we have is actually not very significant. If there comes a time when we need to get back to where we had a decent civilization and knowledge it shall be on printed form, not electronic. There are too many examples already where electronic data is unreadable because the hardware to read it no longer exists and has been replaced by more efficient means. Of course - it's not very hard to re-create punched card readers and punched tape readers, but how many have the means to read 8" floppies today?

When I refer to information that isn't significant - then I think of all the tax records and statistics accumulated. It's numbers, but you can't really do much from them. Engineering handbooks on the other hand are very useful when rebuilding. Metallurgy, chemistry, mechanics, physics are all things that are good to know in order to be able to rebuild. Medicine is of course also useful. It is probably enough with information to fill a few bookshelves. Historic records can be added as a secondary set of items, but they are harder to use if you lack the references, and how can we know what is real and what is fiction?

Just beware us from religious extremists like Nehemiah Scudder [] .

And if you create printed material that shall survive a cataclysm - use the Rosetta Stone technique - same message in multiple languages/writings. And lock it up into vaults spread over the world that requires skill rather than brute force to open and access. Place them in geological stable and dry places that are rarely accessed by humans today. Punch it on stainless steel sheets or something.

There is one form of information that is very significant for future generations - the locations and contents of Nuclear burial sites. The film 'Into Eternity' about the Finnish sites documents this issue - how do we make sure humans, perhaps 100,000 years hence, understand the nature and toxicity of the contents, without making them curious about discovering what lies within. The Egyptians tried this 4,000 years ago - writing messages warding off potential interlopers to their sacred burial sites. That outcome is perhaps an indication of how a future civilization would perceive our messages.

Re:Already Been Invented: Fired Ceramic Tablets (4, Interesting)

K. S. Kyosuke (729550) | 1 year,27 days | (#44181665)

Please note that they weren't fired, originally. They didn't have that much fuel in Mesopotamia to fire everything they wanted. Ironically, many of the preserved tablets come from libraries that burned down in random fires. These events stopped being celebrated by archaeologists after Middle Easterners switched to other writing materials around 100 CE.

Re:Already Been Invented: Fired Ceramic Tablets (2)

MozeeToby (1163751) | 1 year,27 days | (#44181851)

I think that's a good place to start, but more detail is always interesting:

I would start with a Rosetta Stone, specifically designed to explain as much of the language and text as possible. Included in those would be directions, both in terms of location and recovery procedures, to a much larger collection of paper documents stored in sealed casks of an inert gas to prevent degradation. From there it would be possible to at least describe the basic procedures and formats needed to read much, much denser long term storage options, I thought I remember reading about modified DVDs that would be stable across centuries.

You can either assume that the discoverers will reinvent basic electronics, or, if you have the capacity in your paper archive, lay out a plan that would get them there. If you assume say early 1800's level tech for example, would it be possible to bootstrap them to reading data from a DVD using only printed word? Could you describe the materials, designs, manufacturing techniques necessary? Would they even care enough to try to follow the directions? If you can get them that far you could have petabytes of data stored and ready for use... but that's a big if.

Re:Already Been Invented: Fired Ceramic Tablets (1)

Darinbob (1142669) | 1 year,27 days | (#44182067)

You also need the method to decode the tablets. Ie, a Rosetta Stone type of mechanism. Provide multiple languages, hints on the algorithms used, diagrams on how to interpret the data, and so on.

useless without infrastructure (1)

Gothmolly (148874) | 1 year,27 days | (#44181473)

Say a cataclysm wipes out major cities, centers of learning, large chunks of the population, etc. but that you managed to preserve the exact DNA and RNA sequences of a lab rat. Without the machinery to use the data, and indeed without the entire medical industry to provide materiel for research using that knowledge, what does it really buy you? Or you preserve the technical schematics of the Tokamak reactor. When you're burning firewood for heat because the entire fossil fuel delivery aparatus is destroyed, who cares?

There's a degree of materials and available resources which would be available after a 'cataclysm' - the knowledge you'd need after that probably boils back down to the early industrial revolution.

Re:useless without infrastructure (4, Interesting)

HappyHead (11389) | 1 year,27 days | (#44181903)

While that's true to some extent, it doesn't mean that knowledge shouldn't be preserved in a format that would be accessible by a recovering civilization. Just because they don't have electricity now, doesn't mean they never will, and a handy guidebook telling them how those things work will speed things up later.

It does mean though, that the information should be prioritized - there's a T-shirt/poster floating around the internet full of "things to take credit for discovering if you go back in time". Most of the items it lists are either critical discoveries that led directly to improvements in quality of life, or were the basis for other technologies. Pasteurization, antibiotics, electric generation, radio, flight, and more. (It's here [] by the way.)

A guide like that is a good start - build things up in stages, add in more (useful) detail, never assuming that the reader will already have a tool unless it has already been explained how to make it. Then if you want to go hog-wild, after you've reached the part explaining how to make a computer and digitize information, put the stuff that would require a heavily industrialized civilization into a digitized code format and explain how it's encoded, so they can read it when they're ready/able to use it.

Random data being used for research though, is likely totally useless. Not only is the DNA/RNA sequence from that rat likely to be useless to a recovering civilization, depending on what sort of cataclysm happened, the DNA/RNA of a rat may not even match what was recorded. Leave stuff like that to DNA/Seed banks, unless it's part of an explanation of "what DNA/RNA is", and even then, the whole set is pointless. (Also probably patented.) A Tokamak reactor may not be useful to a low tech civilization, but with the boost provided by being taught how to make hydro-electric generators, lights, heaters, radios, and internal combustion engines (they can run on cheaply made alcohol, they're just less efficient that way, and wear out faster.), they might be able to make use of that information in only a few generations.

The real problem of course, is format, and ensuring that not only does the information survive, but that these future people are able to understand it when they do see it, rather than thinking "Oh, pretty metal plates with squiggles on them. I bet I could melt those down and make a great set of knives out of them."

Re:useless without infrastructure (2)

bonehead (6382) | 1 year,27 days | (#44181943)

The data may not be useful immediately, but presumably society would begin rebuilding at some point.

It may be a long time before the information is useful, but once that time arrived, it would save a great deal of wheel re-invention.

Remember that virtually every nontrivial monument/tomb site that we know about was plundered, often pretty quickly after it was built, sometimes several times. If you want to preserve something, it either has to be so valuable that the succeeding civilization continues coddling it, or so worthless that it doesn't get melted down for scrap(unfortunately, given that people will scrape and reuse parchment [] and use mummies for fuel, the bar for this is pretty low indeed).

SuricouRaven (1897204) | 1 year,27 days | (#44181563)

If you're planning for the fall and rise of civilisation, you need to prepare for the possibility of deliberate destruction - it's possible that a future civilisation might be so sickened by the actions of the past they seek to destroy all their works, or a religion might emerge which considers your documents heretical and in need of destruction, or perhaps a king feels that his people are living in the shadow of legendary greatness and only by destroying the legend will their story be honored.

So you're going to need to mass-produce whatever storage media you choose - make them by the millions and put them all over the world. In museums, in caves, burried or sunk offshore (Add a big chunk of iron, ready for when the metal detector is reinvented), as many as you can. So many it'd be impossible to destroy them all.

As for the actual storage medium? Tiny etchings on iridium would work. It's corrosion-resistant, and very, very hard wearing. It's last for millenia with ease, even in burried in moist soil or scoured by desert sand, and with such a high melting point it'd be untouched even if the containing building burned down. The only issue is the price: That stuff is expensive. Really expensive. It's cheaper than gold, but not by much.

Repeatedly gained and lost knowledge? (3, Insightful)

brit74 (831798) | 1 year,27 days | (#44181587)

I'm not sure that I can really think of good examples of this happening - at least not on a global scale. Sure, there was a regression in Europe after the Greeks and Romans. There were quite a few works lost. And it seems that there was a very early civilization around India that was abandoned (apparently due to crop failures). But the main protection for lost knowledge seems to be to spread knowledge around the world. The world has never simultaneously regressed (the Middle East and China weren't doing so bad during the European dark ages). The works of the Greeks wouldn't have been lost if their writings had larger distribution (instead of being confined to a relatively small area, which makes the fate of those earlier works dependent on the local conditions). As long as people keep writing and reading books, I don't see how much knowledge is going to be lost. There wasn't even much knowledge lost in Europe during the Black Plague - and that killed off 1/3rd of the people in Europe.

Perhaps the concern over "lost knowledge" says a lot about people's perception that some massive apocalyse is going to happen. I think, in general, people tend to grab onto ideas about "apocalypse" (which necessarily results in some massive social rearrangement) because they're not happy with the state of the world. Apocalyptic thinking is a little bit of a fantasy about starting over.

Re:Repeatedly gained and lost knowledge? (1)

The electrical grid is essentially a big pile of copper. Solar storms might knock out transformers and such, but the bulk of the infrastructure would be unaffected. You wouldn't need to rebuild, just repair the delicate parts. It could be time consuming, but not unmanageable. With modern sun monitoring, we would probably know about any really big storms and just shut down the grid, so that we'd only have to worry about what harm comes from inducted currents. Electronic equipment might be a different story.

Probability fail (1)

Okian Warrior (537106) | 1 year,27 days | (#44182025)

As the span of time reaches infinity the probability of a global catastrophic event approaches 1. It *will* happen eventually.

This assumes a fixed probability over all time.

If the probability lowers over time, then the cumulative probability can be bounded to any chosen value.

Consider: is the probability of world-wide plague higher or lower than it was 300 years ago? The probability of large-scale crop failures? Nuclear war?

You could say that the probabilities are higher in each case, yet the historical statistical evidence shows that the number and severity of wars has decreased, plague vectors have been detected and averted (SARS, Bird flu), and crop productivity has skyrocketed beyond all projected yields.

Statistically speaking, we're much more secure in our civilization simply because we are more aware of our surroundings, are smarter, and have more technology to apply to problems.

We're even beginning to discuss and proposing solutions to asteroid impacts.

The probability of a global catastrophic event is decreasing. If it hasn't happened yet, it'll become ever less likely in the future.

Of course it will, but with some luck earth wont be our only place to live by then. He is still right with what he said, spread knowledge as far and wide as possible and it will mostly survive. I do think the only knowledge worth spreading would be real scientific fact. Just think about those small games back when you were young where you had to whisper a sentence from person to person, getting it all distorted in the end. Only things that can be verified would actually survive being passed from person to person, Religion and culture probably will not survive that long, certainly their actual intention may be lost even if the books and so on describing it are not. Just look at how many different groups interpret the bible in different ways. The stories themselves may survive intact but the meaning behind the stories will not. Math will, scientific fact will.

'permenant preservation' (1)

oneiros27 (46144) | 1 year,27 days | (#44182071)

You'd be surprised.

At a meeting a couple of years back, I was talking to someone that I think was the head of the British Library (I remember 'head of' and 'British' even though he was an American) We talked about some of my work in trying to come up with definitions that different communities can agree on, and he said that he had been at a meeting of archivists and they were having trouble defining 'permenant preservation'.

He said they came up with a definition that was effectively 'make sure we can understand it tomorrow, then do the same thing tomorrow'

Collapse of civilization is less not so common (1)

jellomizer (103300) | 1 year,27 days | (#44181667)

Back in the ancient times civilizations had small centers of learning and education, where a good disaster could clear out civilization and they more or less need to start over. However now information is spread across the world. A super volcano kills the US. Europe and Asia still has most of our information and society will continue on, and vice versa.

A major super major disaster would probably send us back 70 years. And would probably take us 30 years to recover.
We as people know about the internal combustion engine, transistors, optics... And could rebuild with our experience. Back in ancient times average joe knew how to make fire, the wheel and farming techniques. So a civilization was killed off, they didn't go have to reinvent the wheel, they already know how to make it. However in ancient times a small number of people understood mathematics, science, and reading, so it could get killed off and needed to be rediscovered. Not so much anymore today.

We are currently looking at our petty issues of today such as Bad economy and not having enough money for Food, Housing, BlueRay Player and an iPad, and having to pay for Cable too. So we are a bit depressed, people are protesting the government about stuff that governments tend to always do. And global warming creates more weather disasters that hit small areas. What is the East Coast compared to the rest of the world.

So if you want to be prepared for a collapse in civilization, think what they had in the 1940's

Not an obviously tractable problem: (2)

fuzzyfuzzyfungus (1223518) | 1 year,27 days | (#44181671)

Barring the development of a strong-AI level pedagogical expert system that can be stashed away somewhere, the task of actually preserving the present state of human knowledge in the absence of the background is pretty difficult.

Mere storage is actually the easy part: Even clay tablets have a modest survival rate when you burn the civilization that inscribed them down on top of them, and with modern materials and machine tools, we could mass produce something better(or really, really, really mass produce something cheaper, and distribute it all over the world).

The trouble comes once you start dealing with knowledge that exists largely in the form of continually-refreshed human capital, and with tools that exist largely in the form of a long chain of worse tools building better tools building better tools, etc. The amount of pure written knowledge you would need to restart/rebuild all the supporting industry to refill, say, a totally undistinguished hardware store, would be considerable, quite probably more than actually is written down(rather than learned on the job by the new guy from the old guy, and fabricated on tools that were built with parts fabricated with tools that go back to the early 20th century if not earlier).

You also run into encoding problems. "Graecum est; non legitur", and that was the allegedly educated class in a civilization that probably had some greek speakers available(and it'd hardly been a global thermonuclear holocaust that ended classical civilization). You'd need to choose some human languages, and god help you with the digital file formats...

Batman and Long Now (1)

Hotawa Hawk-eye (976755) | 1 year,27 days | (#44181677)

In one of the episodes of the animated series The Batman, future archaeologists unearth the Batcave and find information etched in binary on the titanium support pillars. []

Alternately, I wonder what projects the Long Now Foundation [] has in the works to do something like this. The Wikipedia page lists the Rosetta project but there may be something else for general knowledge.

In our DNA (0)

Anonymous Coward | 1 year,27 days | (#44181687)

The most secure way to preserve information is inside ourselves.

So, find a way to create "trash DNA" that don't generate proteins or any other changes, do it with huge redundancy (the same information in parts repeated sometimes, so mutations could be tolerated in a great degree), and we carry this information by generations, without risk of destroy the recipient of information, because it'd be on us.

Impossible (1)

Going_Digital (1485615) | 1 year,27 days | (#44181691)

It is quite simply impossible to preserve something for ever. What ever format you use to store the information assumes that the people in the future will be able to read it. Lets for example imagine that in the event of a catastrophic event that some civilisation other than America are the ones that service. Perhaps for example it is an obscure eskimo tribe that survives and it takes them two centuries to re-colonise the world to the point where they will discover your data left in America. How will they understand the English that has been written and even if they can translate it, what meaning will it have to them, the world might be a very different place by then. language changes so fast just try reading some Olde English from the 17th Century and see how you get on. We largely have translations of old languages like Ancient Greek and Hebrew used in the Bible as there has been an evolution of the language and so it has been possible to study the way the language has changed and work backwards, but translation is not an exact science hence why there are still disagreements over the exact translation of the bible to this day, hence the essence of you message may be lost. The best we can hope for is for institutions such as archives and libraries will continue to preserve information for the future and that enough of our civilisation survives to pass the information into the future. Hoping of corse that some religious nutters don't don't destroy it all like the Christians did with the library in Alexandria because the material didn't fit with their ideals.

Deadman switch courier ships (5, Interesting)

Intrepid imaginaut (1970940) | 1 year,27 days | (#44181703)

Periodically send up long distance spacecraft loaded with not just data but the means to view it and the means to rebuild from first principles, assuming a child was viewing it - here is how you find iron deposits, mine and refine them, this is how you forge ploughs, these are the basics of algebra. Have them programmed to circle around somewhere just inside Jupiter's orbit, and have multiple stations here on earth sending out a deadman signal - when they stop broadcasting, the vessels begin to return in waves seperated by ten years or so, with the last waves arriving once a century.

When they make it home, have them attempt to locate likely inhabited areas whether by thermal imaging looking for fires at night or just vegetation profiling for fields, then drop down nearby, broadcasting light and sound, even radio, until someone comes to investigate.

It's relatively easy to permanently preserve all of mankind's knowledge, just pack it in a rocket and send it Oort-cloud bound. Well permanently as in astronomical timescales. The trick is to preserve all of humanity's knowledge in a way that's useful to humanity in the future.

Alternatively, are we, as a species, willing to start over if we experience a catastrophe, pandemic, etc. of significant magnitude on a global scale that derails our progress and sends us back to the dark ages or worse?

Willing? Like we have control over the cosmos and would choose to hit ourselves with an asteroid, or get decimated by a plague? First thing is to set expectations on "permanent", because in reality...there is no such thing. The Earth, the Sun, even the universe has an expiration date. In order to even begin to narrow the types of materials needed you would need to define the duration of "permanent" before you went anywhere. I couldn't dig it up but I seem to remember an article online about something like this. Using thin diamond sheets to encode information into or the like that would be able to survive hundreds if not thousands of years intact if locked away like the seed vault [] . If I find it I will reply to this if someone else hasn't posted it elsewhere in the thread.

It's very simple. Anything you want to preserve forever, publish it in National Geographic. It will be printed 30 million times, distributed across the world, and stored permanently in people's basements. Losing it permanently requires losing all of those basements.

Equivalent question & Corollary (1)

NEDHead (1651195) | 1 year,27 days | (#44181835)

This is the same as asking what information & how to preserve it for a generational starship. While en route there would be limited need for much of the accumulated knowledge, but once established as a distant colony, that would change.

Corollary would be: what is the minimum population required to maintain the diverse productive capacity that feeds our standard of living (both #'s of diverse producers and consumers to achieve satisfactory economies of scale) ( acknowledging that on demand production is coming) and product development improvements.

Microfiche lasts about 5x as long as paper and is 98x more efficient space wise. It can be read with a magnifying glass and a light source.

That's going to be hard to beat.

kannibal_klown (531544) | 1 year,27 days | (#44181963)

I always loved microfiche... I thought it was cool. Back when my middle school wasn't very big on PC's we had loads and loads of microfiche that we could print out and stuff.

But, it does have some disadvantages. Heat and humidity can distort the image, and eventually damage the film by either distortion or fungus.

However I don't know what the threshold temperatures are.

After we're done with our resources, with what dou you want to rebuild ?

We're already facing major shortages of non-renewable metals and ores in the next 50 years.

After we're done with this planet, there won't be enough left to rebuild a civilization.

I've seen a number of essays on this topic, especially since the invention of computers. this was commonly suggested. we've learned to decode the lost scripts of forgotten languages, e.g. Egyption, cuneifomr, assuming we have enough text.

It depends a bit on the question you ask. (0)

Anonymous Coward | 1 year,27 days | (#44182077)

Preserve stuff for a long time? If long enough, either there'll be nobody left to read, or they can't read at all, or they now speak some other language and it's all academic anyway. Possibly. So not that interesting.

As to whether we want to start over after a catastrophe, well, either we do, or we get to live like, nay, we'll be like cavemen again. That or we simply die off. Take your pick.

There's been various projects, like long information storage, or the basic few machines to start a farm, or whatnot. You can also look at what the Amish do, or other subsistence farmers. Another interesting thing is what's called the "appropriate technology" idea and movement. An euphemism to patronise the developing world again, so it's ultimately not going to work, no matter how good the technological ideas or the intentions. Meanwhile, the ideas are interesting in and of themselves.

There's also the "living history" and bushcraft people. They have some interesting tricks to share.

My angle was that of the following question: You're left with any knowledge you've cared to've gathered beforehand. No limit on how much you can take (as a first approximation). But you can't have anything else.

Nothing. No clothes, no guns, not even knives. Anything beyond the knowledge you must make, and that includes making the tools to make the tools to make the tools. Now build up the tech base again, to at least, arbitrarily, 19th century.

What knowledge do you need for that? Go and work it out and maybe make a dependency chart. You're allowed to take shortcuts from what history did, but it has to be doable from scratch.

How you'd preserve that knowledge is another project entirely. But you need a base line to inform just what you need to store and how to store it--if your intended audience can't read it, it's useless. So I'd take a relative short term view and update as time moves on.
