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?"

      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too many examples already where electronic data is unreadable because the hardware to read it no longer exists and has been replaced by more efficient means.

        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.

Were it not for the fires, and the accidental firing of the tablets thereby, its doubtful whether the tablets would have survived so well. As any archaeologist can attest, ceramics tend to stick around even as civilizations collapse about them.
    • I think that's a good place to start, but more detail is always interesting:

From there it would be possible to at least describe the basic procedures and formats needed to read much, much denser

      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 [geekologie.com] 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."
    • by bonehead (6382)

      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.

      • Why are we assuming a cataclysm? Yes, there may be one, and we have to prepare for the worst, but we should also make as much available via technology as well. A thousand copies of an encyclopedia on thumb drives perhaps? In that case they'd probably have all the data, but the quaint snapshot of what we knew at the time would be of interest, too.

      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 [wikipedia.org] and use mummies for fuel, the bar for this is pretty low indeed).

    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.

    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.

    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).

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.

    That's going to be hard to beat.

    • 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.

      it won't last at all in the scenario we're discussing here. depending on base, microfilm/microfiche must be kept form 15 to 40 percent (cellulose) or 30 to 40 percent humidity (polyester) or it will crack (too dry) or decompose (too wet). fumes from wood, particle board or paper will destroy it. sulfides, peroxides, and hydroxides like ammonia will destroy it Temperatures greater than 70 degrees F over time will destroy it. More than five percent temperature variation during the day will ruin it.

        Didn't realize 5 degrees. What about in a cave?

        • by iggymanz (596061)

          maybe a "lava cave" in inactive area would be a good place if cool.

          Not the kind of caves we have in central USA which are water formed in limestone. things will get buried in limestone as the stuff is dissolved and precipitates by rainwater.

    I regularly carve pictures and patterns into various rocks around my property. I often wonder what future scientists will think of them. And now I wonder if someone will try to construct something meaningful in the crap I leave around my ranch...

  • Durable, easy to read.

  • Tint printed letters old plates (Holy Joseph Smith!) or some ceramic. This presumes the technology of hand lenses will be remembered or reinvented. 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.

    Most of the books from classical times were passed down by copying them periodically. Very few original texts from that era, save on stone. Generally educational classic or important religious works were worth copying.

    If you're not familiar with The Long Now Foundation [longnow.org] you should check them out. They have a project to build a clock that will last 10,000 years (about as long again as there's been civilization on earth), and are making progress constructing it in a cave in a mountain in Nevada [longnow.org].

    Of course, the next questions are things like "well, who is going to be around to read it?" and "how will they read it?", and "how do we maintain a level of civilization where people can create replacement parts for it?"

    Neal Stephenson consulted with them for his book Anathem [wikipedia.org], which I highly recommend, which is based around these sorts of questions.

  • Any novel "ultra durable" technology will not be ubiquitous. Pre-digital age technology (aka, paper books) will be everywhere. Even though they are slowly deteriorating, just 0.1% preservation of such material will preserve a lot of knowledge because it was so widely disseminated. That's just my guess though. You can't predict the outcome of a dark age any better than you can plan it.

  • These days a lot of information about engineering various things is possessed by companies with availability to a small group of people. When they abandon the product, the internal information may be just nuked instead of publishing it openly. Many inventions, which are useful to the humankind in general, are produced in proprietary manner. I think this is problematic.
  • In the George Pal version of H.G.Wells' "The Time Machine", the intrepid traveller comes upon a flat desk with a series of rings arrayed around. He spins a ring, and the story unfolds... a little hologram appears, with the message

    "Help me, Obi-Wan Kenobi, you're my only hope."

    Or words to that effect.

    The optimists:

    the pessimists:
    http://en.wikipedia.org/wiki/Earth_Abides [wikipedia.org]

    the second kind doesn't need any storage of information I would think.
    Some might not even call them optimists or pessimists.

  • Most of the rest is cool and stuff, but way overrated. Man's quest for knowledge is the irony spelled out in the first few pages of a book despised by those described therein.

    Since the NSA seems hell-bent on collecting every scrap of digital informaiton created, presumably they've worked out how to store and preserve it. I would assume their server room is well hardened.

    So all future archaeologists need to do is to get in there somehow, boot it all up and have the whole of the 21st century fall open at their feet. Of course they'll be horrified at the kind of world we made for ourselves, but at least the reason for the apocalypse will be obvious, so they can avoid making that
