Jesse Schell’s Recommended Reading

Published on Thursday, July 29th, 02010 by Austin Brown

During his Seminar, Jesse Schell recommended a number of books and other resources that have informed his conception of the Gamepocalypse.  Here’s a list of the books for the curious:

He also mentioned a movie called Frequently Asked Questions About Time Travel, a website called Couch to 5K, and plenty of other fascinating things.  Oh, he’s on twitter too: @jesseschell

Building an Audio Collection for All the World’s Languages

Published on Wednesday, July 21st, 02010 by Laine Stranahan

The Rosetta Project is pleased to announce the Parallel Speech Corpus Project, a year-long volunteer-based effort to collect parallel recordings in languages representing at least 95% of the world’s speakers. The resulting corpus will include audio recordings in hundreds of languages of the same set of texts, each accompanied by a transcription. This will provide a platform for creating new educational and preservation-oriented tools as well as technologies that may one day allow artificial systems to comprehend, translate, and generate them.

Huge text and speech corpora of varying degrees of structure already exist for many of the most widely spoken languages in the world—English is probably the most extensively documented, followed by other majority languages like Russian, Spanish, and Portuguese. Given some degree of access to these corpora (though many are not publicly accessible), research, education and preservation efforts in the ten languages which represent 50% of the world’s speakers (Mandarin, Spanish, English, Hindi, Urdu, Arabic, Bengali, Portuguese, Russian and Japanese) can be relatively well-resourced.

But what about the other half of the world? The next 290 most widely spoken languages account for another 45% of the population, and the remaining 6,500 or so are spoken by only 5%–this latter group representing the “long tail” of human languages:

Equal documentation of all the world’s languages is an enormous challenge, especially in light of the tremendous quantity and diversity represented by the long tail. The Parallel Speech Corpus Project will take a first step toward universal documentation of all human languages, with the goal of providing documentation of the top 300 and providing a model that can then be extended out to the long tail. Eventually, researchers, educators and engineers alike should have access to every living human language, creating new opportunities for expanding knowledge and technology alike and helping to preserve our threatened diversity.

This project is made possible through the support and sponsorship of speech technology expert James Baker and will be developed in partnership with his ALLOW initiative. We will be putting out a call for volunteers soon. In the meantime, please contact rosetta@longnow.org with questions or suggestions.

Ancient Cosmic Light

The European Space Agency has released an amazing new image of our universe, created by the recently launched Planck mission.  The image above comes from Planck’s first detailed survey of the cosmic microwave background, the universe’s “first light.”

It is the light that was finally allowed to move out across space once a post-Big-Bang Universe had cooled sufficiently to permit the formation of hydrogen atoms.

Before that time, scientists say, the cosmos would have been so hot that matter and radiation would have been “coupled” – the Universe would have been opaque.

Planck is funded to create four of these surveys, each more precise than the last:

“We know that eventually as the data get better and better, what you end up getting to are the limitations of what you know about the instrument,” explained Professor Jaffe.

“And so, by running Planck for longer we can learn a lot more about the instrument itself and thereby remove a lot of the contaminating effects that are just because of the way it produces its noise.”

Digital Time Capsule Buried in Swiss Alps

Published on Thursday, June 3rd, 02010 by Heather Louise Mae Bowden

In order to demonstrate digital impermanence, scientists from the European Planets Project deposited a time capsule containing five of today’s most common types of digital objects into the Swiss Fort Knox data center. The time capsule contains a JPEG photograph, a message in Java source code, a short film in .MOV format, a web-page in HTML and a brochure in PDF.

According to the Planets website, the deposited box also included..

…conversion tools that were used to migrate the objects as well as software to open and view/use these objects and supporting software all the way down to an operating system; descriptions of the file formats, of the file systems and encodings used on the storage media; and description of all these objects and their relationship to supporting technology and recognised standards.

The TimeCapsule will be available to researchers in the future to investigate how much of its content will still be or can be made accessible and usable with the information provided.  An online version will make it possible to see the contents of the TimeCapsule and experiment with technology to preserve them. Replicas will be available to libraries, archives, science museums and others for research and public exhibit.

The Planets TimeCapsule will demonstrate in ten, 20, 30, 50 and hundreds of years the fragility of digital data and the ability of technology to overcome it.

Scientists vs. Pulsars

Published on Wednesday, April 14th, 02010 by Austin Brown

Clocks

Technology Review has an article up in which some physicists defend their clock-making chops.  It seems they feel pulsars are getting more credit than they deserve in the public perception of accurate time-keeping:

So accurate are pulsar signals that when they were discovered, astronomers gave serious credence to the idea that they were evidence of intelligent life elsewhere in the Universe because they were unmatched by anything physicists could make on Earth. This has lead to the widespread belief that pulsars are the most accurate clocks in the Universe.

John Hartnett and Andre Luiten at the University of Western Australia want you know that’s no longer the case.

Today, the best optical lattice neutral atom clocks and trapped ion clocks have a frequency stability approaching one part in 10^17.By contrast, as more pulsars have been discovered, their timing stability has improved by less than an order of magnitude in the last 20 years. The best millisecond pulsars have a stability of only one part in 10^15 at best.

That means that terrestrial clocks can rightly be crowned the best clocks in the Universe, say Hartnett and Luiten.

Duly noted.  It seems worth pointing out that the measure of accuracy in the article is expressed as a ratio without units – often you hear that an atomic clock will lose a second of accuracy only every 10 billion years or so.  The author of this article avoids that, and maybe for good reason.  Sometimes people told Long Now is building a 10,000 Year Clock react by asking, “Oh, like an atomic clock?”   It seems that an occasional side-effect of using these long time units to illustrate the accuracy of atomic clocks is the implication that they will be around for eons.

The thing is, atomic clocks rely on vacuum-sealed chambers full of cesium atoms kept near absolute zero or similarly complicated mechanisms to make their extremely precise measurements.  That kind of hardware requires a significant technological, economic and bureaucratic infrastructure to maintain.  If you can imagine finding an atomic clock after the electricity failed that kept it running, you would have to recreate a lot of knowledge to understand what in fact it was.

The article goes on to discuss the difficulty of building a timepiece durable enough that its lifespan requires scientific notation to describe, and mentions Long Now’s attempt through the Clock of the Long Now. It’s in this endurance category, however, that pulsars maintain their dominance, as they’re likely to last quite a bit longer than anything humans have been able to build, even Long Now – we’ve been able to observe some that are thought to be around 200 million years old.

Manual for Civilization

Today we received another email about creating a record of humanity and technology that would help restart civilization.  The latest one is inspired by an essay that James Lovelock published in Science over 12 years ago called A Book For All Seasons (excerpt):

We have confidence in our science-based civilization and think it has tenure. In so doing, I think we fail to distinguish between the life-span of civilizations and that of our species. In fact, civilizations are ephemeral compared with species. Humans have lasted at least a million years, but there have been 30 civilizations in the past 5000 years. Humans are tough and will survive; civilizations are fragile. It seems clear to me that we are not evolving in intelligence, not becoming true Homo sapiens. Indeed there is little evidence that our individual intelligence has improved through the 5000 years of recorded history.

Over the years these proposals have been in different forms; create a book, set of books, stone tablets, micro-etched metal disk, or a constantly updated wiki.  I really like the idea of creating such a record, in fact the Rosetta Disk project was our first effort in this direction.  These Doomsday Manuals are a positive step in the direction of making a softer landing for a collapse, and the people creating them (like ourselves) are certainly out to help people.  It took millennia for the world to regain the technology and levels of societal organization attained by the Romans, so maybe a book like this would help that.

However it also seems that these efforts tap a romantic notion that we would all love to find something like this book from a past or otherwise alien civilization.  My worry is that it also feeds off a (likely incorrect) feeling that somehow collapse might be a fun challenge to live through, and that everyone kind of wants to be the monk in A Canticle For Leibowitz or Mel Gibson in Road Warrior.

My bet is that the reality of watching your civilization (and population) collapse is likely one of the worst things anyone could experience.  I am also not so sure the problem is just knowing how to remake a technology.  For instance after the fall of the great Egyptian, Mayan, and Roman empires we had evidence and examples of their engineering achievements all around us.  But aqueducts or senate buildings are worthless without a society around them to maintain, contextualize and protect them.

It is also worth pointing out that there are likely well over a billion people on earth who currently don’t interact with formal economies or technological society at all.  They will be very well adapted to a post collapse world, you should find some and make friends.  They will likely be far more helpful than a manual on restarting the internet, because they know how to gut a deer.

In any case I thought I would create this blog post which I will try and keep updated as these proposals and efforts come to me (and hopefully come to fruition).  I will also list some of the resources that I usually refer to when I get these inquiries.   Please note these resources are extremely biased toward the English language, the United States and Western culture.  Also note that one of the first things that comes up when creating any compendium style work is the issue of copyright.  It might sound ridiculous that you might worry about copyright in a doomsday manual, but if you want to publish it and get it into peoples hands before the apocalypse, you are going to have to deal with it in some way. Please feel free to use the comments field to make suggestions and pointers and I will integrate them here as well.

Projects that are attempts in this direction:

  • The Rosetta Project: A multi-millennial micro-etched disk with a record of thousands of the worlds languages.
  • Westinghouse Time Capsules: Two time capsules (they actually coined the term for this project) by Westinghouse buried at Worlds Fair sites, one in 01939 and the other 01965 to be recovered in 5000 years.  They also did the very smart thing of making a “Book of Record” and an above ground duplicate of the contents on display.
  • The Human Document Project: A German project to create a record of humanity that will last one million years.
  • Crypt of Civilization: A airtight chamber located at Oglethorpe University in Atlanta, Georgia. The crypt consists of preserved artifacts scheduled to be opened in the year 8113 AD.
  • The Voyager Record: The Voyager Golden Record are phonograph records which were included aboard both Voyager spacecraft, which were launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or far future humans, who may find them.
  • Georgia Guidestones: The four granite Guidestones are covered in inscriptions written in 8 major languages that describe the tenets of their imagined Age of Reason.
  • (added) Doomsday Chests by Noah Raford
  • (added) The Forever Book an idea by Kevin Kelly

Content that has been discussed to be used for these projects:

  • The Gingery books always seemed to me to be a great first pass on how to re-start manufacturing technology
  • (added) Wiki How has a lot of great info and it is continuously updated.  The entry on how to deliver a baby seems like a particularly handy one…
  • (added) The Foxfire Books on homespun technology seem to have a slightly less industrial take than the Gingery books, and are pretty comprehensive
  • (added) The Lets Say Youve Gone Back in Time poster to help you restart civilization by Ryan North the creator of the awesome Dinosaur Comics
  • (added) The Way Things Work by David Macaulay.  This is a fantastic book, but it might leave people thinking that all technology is powered by woolly mammoths and angels.
  • The Harvard Classic‘s originally known as Dr. Elliots Five Foot Shelf are often referred to as an item that should go into a record like this.
  • Encyclopedia Britannica People often suggest using the latest version that is now out of copyright.  I believe this is the 13th edition but so far I have only found digital copies of the 11th.
  • The Domesday book: The Domesday Book is the record of the great survey of England completed in 1086.  It would be interesting to find surveys and census’ from around the world
  • The Mormon Genealogical Data:  This is also held in a bunker outside Salt Lake City Utah, but it might be nice to have a record of gene lines for a future civilization to better understand its past.
  • The Top 100 Project Gutenberg books: If you are concerned with archiving works in copyright this is a great source to find texts that are free to use.
  • The Internet Archive: An archive of complete snapshots of the web as well as thousands of books and videos.  Incidentally you would also get all of our scanned page content from the Rosetta Project with this.
  • Wikipedia: The text only version of this is actually not that large, and could be archived fairly easily.  Also one of the few sources that is beginning to get filled out in many languages and is also not held under a copyright.
  • How to field dress a deer: PDF pocket version from Penn State College of Agricultural Science (living in Northern California, I think this one will be especially handy).

Dumpster Diving for Science

Published on Thursday, April 1st, 02010 by Austin Brown

Or: Techno-Archaeology and the Tale of the Whale-Oil Tapes

Weather satellite data from 1966

Researchers at NASA’s Ames Research Center recently were able to recover some very old and useful data.  The Nimbus II satellite created a detailed mosaic of the earth’s cloud cover and heat radiation in 1966.  Such old and detailed climate data is a boon to today’s researchers, but it wasn’t easy to come by.  Indeed, the data was lost for quite some time due to the tapes on which it was recorded – the secret to their longevity was whale-oil, but it became unattainable in the 1980′s due to the cessation of commercial whaling.  Since they couldn’t get more long-lasting tapes, NASA chose not to keep the old data, but rather to rewrite the tapes with newer data that they decided needed to be preserved for the long-term more than the old data that, when it was new, needed to be preserved for the long-term but, once it was old, did not.  Some 200,000 tapes endured this fate.

What about the machines used to read the tapes?  Perhaps it was a form of penance: many of them ended up being dumped into the ocean to create coral reefs. Fortunately, a team of techno-archaeologists working as the Lunar Orbiter Image Recovery Project have been working to track down old and lost copies of tapes like these, as well as restore the machines required to read them.  Luckily, some of the Ampex tape drives made their way into the garage of a woman named Nancy Evans, an engineer from Jet Propulsion Laboratory.

The LOIRP team obtained $750,000 from NASA and private enterprise and enlisted the assistance of a retired Ampex engineer. They cleaned, rebuilt, and reassembled one drive, then designed and built equipment to convert the analog signals into an exact 16-bit digital copy. “It was like dumpster diving for science,” says Cowing, co-team leader at LOIRP.

Avoiding a Digital Dark Age

Published on Friday, February 19th, 02010 by Austin Brown

Long Now Digital Research Director Kurt Bollacker was recently published in New Scientist discussing the challenges in maintaining data for the long haul:

It seems unavoidable that most of the data in our future will be digital, so it behooves us to understand how to manage and preserve digital data so we can avoid what some have called the “digital dark age.” This is the idea—or fear!—that if we cannot learn to explicitly save our digital data, we will lose that data and, with it, the record that future generations might use to remember and understand us.

It’s a fairly long and comprehensive piece with lots of good advice and a good description of how the Rosetta Disk tries to address some of these problems.

How is the internet changing the way you think?

Published on Monday, January 11th, 02010 by Austin Brown

John Brockman’s Edge has posted the responses from its members to their Annual Question.  This year they wanted to know, “How is the internet changing the way you think?

There are over 160 short essays from members of ‘The Third Culture,’ or “those scientists and other thinkers in the empirical world who, through their work and expository writing, are taking the place of the traditional intellectual in rendering visible the deeper meanings of our lives, redefining who and what we are.”

There are quite a few Long Now Foundation Board Members that have contributed as well as plenty of SALT speakers, past and present.  Here’s a list with links to their thoughts on how the internet is changing their thoughts:

Mumble in the Jungle

Campbells Monkey

This week, the New York Times ran an article about a recent scientific discovery in the predator alert calls of Campbell’s monkeys.   Strikingly, they seem to have the ability to create complex calls out of multiple elements – a “morphological” (word building) process previously thought to only take place in human language.

Human languages do this all the time – for example the word ‘walked’ is built of two morphemes, one carrying the main verbal action ‘walk’ and the other marking past tense ‘-ed’.  In the case of the Campbell’s monkey, morphemes are often combined to indicate different types of threats.  Previous observations of monkeys have shown that they sometimes use different types of calls for different types of predators, but what’s unique about these calls is that some of them can be combined with other calls to change their meaning.  So, instead of just having a “jaguar!” call and an “eagle!” call as has been observed in Vervet monkeys, Campbell’s monkeys have a “leopard!” call that can be combined with a suffix that changes its meaning to indicate a less specific threat:

Crucially, “krak” calls were exclusively given after detecting a leopard, suggesting that it functioned as a leopard alarm call, whereas the “krak-oo” was given to almost any disturbance, suggesting it functioned as a general alert call. Similarly, “hok” calls were almost exclusively associated with the presence of a crowned eagle (either a real eagle attack or in response to another monkey’s eagle alarm calls), while “hok-oo” calls were given to a range of disturbances within the canopy, including the presence of an eagle or a neighbouring group (whose presence could sometimes be inferred by the vocal behaviour of the females).

- Ouattara, Lemasson & Zuberbühler

Just as artificial intelligence researchers have been busy over the last several decades celebrating each previously-unique human capacity achieved by computers, biologists have been finding behaviors once thought to mark the uniqueness of humans in other animals.  Neurobiologist and primatologist Robert Sapolski recently gave a lecture at Stanford about the uniqueness of humans, which provides a great overview of what we share and don’t share with other animals (as is currently understood).

Similarly, primatologist Frans de Waal has made a career of describing the political, cultural, emotional and moral lives of primates.  His work has illustrated the evolutionary breadth and depth of many human characteristics previously thought to be recent behavioral innovations without precedent and unique to our species.

As artificial intelligence research looks forward to recreating human capabilities it focuses our efforts to understand those capabilities.  Similarly, in identifying in other animals capacities like syntax once thought to be unique to humans, we are afforded a clearer look back on the deep history and development of those capacities.  Looked at this way, it actually did take millions of years to produce the works of Shakespeare.
