From November 7 to 9 of this year, the National Association of Watch and Clock Collectors will hold a symposium and special exhibition at the California Institute of Technology in Pasadena, CA. Entitled “Time for Everyone: The Origins, Evolution, and Future of Public Time,” the event will examine the myriad ways in which we experience, measure, and use time:

“From its natural cycles in astronomy, to its biological evolution, to how the brain processes it differently at various stages of life and under different circumstances, to how we find it, how we measure it, and how we keep it, this symposium will explore many facets of this fascinating subject of unfathomable depth.”

Speakers include author Dava Sobel, as well as Long Now Board member David Eagleman, who will discuss the way our brains perceive and process time.

Coupled with a special exhibit of mechanical clocks, watches, and sundials built by 17th century clock maker Thomas Tompion, the symposium is sure to offer a rich perspective on the way our civilization has engaged with time throughout history. For more information about the program, speakers, and clock exhibit, please visit the symposium website.

Disruptive Technology

We are social animals: it’s by connecting and communicating with others that we’ve managed to survive, thrive, and become “as gods” on planet Earth.

The development of communications technologies has dramatically expanded our ability to connect with the world around us. Wireless networks now allow us to communicate in real-time with people on the other side of the globe; and with the portability of tablets and smart phones, global connectedness has become integral to even the most mundane aspects of our daily lives. It’s no surprise, then, that we’re always on the lookout for new ways and places to log in to the world wide web.

Nevertheless, new research suggests that the use of technology does not always facilitate greater connectedness. In fact, it may occasionally be experienced as quite disruptive.

Several recent studies have shown that people consider the experience of overhearing a person talk on a cell phone far more annoying than listening to two people converse; more so, even, than being surrounded by white noise. These wireless “halfalogues” are so disruptive, researchers argue, because they awaken our innate tendency to make sense of communicative stimuli. Faced with a one-sided conversation, our brain is co-opted by the instinct to fill in the conversational gaps, and can no longer focus on anything else.

These findings recently led The Atlantic Cities to question whether we really want to expand wireless coverage on subways and other forms of public transportation. Though it may be nice to have access to an app that tells you when to expect the next train, we may not want to encourage our fellow passengers to disturb our commute with their cellular halfalogues.

This thought echoes some early skepticism about Google Glass, the tiny wearable computer that is currently being tested by developers. Worried that it will create dangerous distractions and eliminate the last remnants of our public privacy, the New York Times reports, several establishments and even states have sought to pre-emptively ban the device. These concerns suggest that there is a time and place for online communications – and that our pursuit of innovative communicative technology should perhaps involve a debate about whether, and where, we might impose boundaries on its use.

The Economist hosts online debate about the future of driverless cars

The Economist asks:

Are completely self-driving cars feasible in the foreseeable future?

Debating this proposition are Long Now board member Paul Saffo and automotive R&D executive Andrew Bergbaum. Saffo is “for the proposition” – he argues that self-driving cars will be commercially available, and maybe even common, by 02030 – while Bergbaum is against, arguing that legislation and existing business models will hamper roll-out of the technology.

The debate is ongoing on The Economist’s site: opening arguments were posted on Tuesday 4/30, rebuttals will go up Friday 5/3 and closing remarks are to be made on Wednesday 5/8.

Readers are encouraged to participate as well, in comment-form or through voting. Results of the vote are tallied daily and there’s a clear trend over the first 3 days in the direction of Paul Saffo’s stance. Will it hold when the rebuttals are posted? Check in over the next week to see.

A Voice From the Past

If you’ve ever wondered what the inventor of the telephone might have sounded like from the other end of a landline, you may finally have your answer: researchers have discovered and managed to restore a brief recording of Alexander Graham Bell’s own voice.

Famously – if controversially – credited for patenting the acoustic telegraph, Bell (01847-01922) dedicated his life to the science of creating, recording, and transmitting sound waves. He co-founded the Volta Laboratory in Washington, DC, where his team experimented with magnetic sound recording and worked on improvements to Edison’s phonograph. The Smithsonian Magazine writes:

Inside the lab, Bell and his associates bent over their pioneering audio apparatus, testing the potential of a variety of materials, including metal, wax, glass, paper, plaster, foil and cardboard, for recording sound, and then listening to what they had embedded on discs or cylinders.

The laboratory produced a considerable collection of recordings, and kept meticulous records of their proceedings. In the late 19th century, Bell donated a large amount of this to the Smithsonian Institution, where they have been carefully preserved. Sadly, however, Bell’s documentation included little information about the instruments he used to play his own recordings, and so the passing of time and evolution of technology reduced his discs to “mute artifacts.”

So when researchers at the Smithsonian discovered a piece of paper in a collection of the earliest audio recordings ever made that transcribed an 1885 recording ostensibly made by Bell, then matched that to an actual wax-on-cardboard disc sporting the initials “AGB” and the same date, April 15, 1885, they couldn’t just drop it into an old-school player and crank away. (Time)

Now, researchers at the Lawrence Berkeley National Laboratory have managed to bridge this technological divide: they have developed a way to “extract” sound from 19th century recordings. A high-resolution 3D camera allows them to create a topographical map of an audio disc without damaging its surface; a computer can then convert this map into sound waves. Using this technology, the Library of Congress brought the 1885 recording back to life, and found, indeed, a snippet of A.G. Bell’s own voice.


It is “a new invention in the service of invention,” says National Museum of American History curator Carlene Stephens. The Berkeley lab’s new disc-reading  technology has succeeded in restoring a piece of its very own origins: it has revived the legacy – and the voice – of a pioneer in the science of audio transmission.

The Digital Public Library of America

A digital library that makes published material available to anyone with an internet connection, free of charge: a realistic possibility, or a utopian fantasy?

Last April, a contributor to the MIT Technology review questioned whether it could be done: if Google Books had become mired in legal battles with US copyright law, would anyone else be able to figure out how to make published matter publicly available?

But this past week, the Digital Public Library of America celebrated its official launch at a library in Boston. As Harvard University librarian Robert Darnton explains, the Library is a nonprofit “project to make the holdings of America’s research libraries, archives, and museums available to all Americans – and eventually to everyone in the world – online and free of charge.”

Partnering with institutions such as the Smithsonian, the New York Public Library, and ARTstor, the Digital Public Library of America is not a database but a “distributed system of electronic content.” Rather than reinvent the wheel of digitization, it embraces what existing libraries and other organizations have already scanned in, and simply works to bring these resources together on a single, openly accessible, and nation-wide platform.

Unlike Google Books, the DPLA doesn’t hoover up institutions’ documents to be stored on its own servers. Its primary goal is to support coordinate scanning efforts by each of its partner institutions, and to act as a central search engine and metadata repository. Most of these libraries and museums have been slowly scanning and cataloguing their collections for years; the DPLA helps make those materials aggregatable and interoperable. (

In efforts to contribute to a truly universal spread of knowledge, the Digital Public Library of America offers a user-friendly interface and a searchable collection of materials under a Creative Commons license: “We are really fighting for a maximally usable and transferrable knowledge base,” says executive director Dan Cohen. Though the Library will – for the moment – refrain from offering anything that is currently under US copyright protection, part of its mission is to explore alternatives to existing copyright laws. As The Verge explains,

[Cohen] wants to create a platform where academic scholarship, whether in journals or monographs, can be disseminated and preserved in open formats for current and future generations. He wants to find ways for public libraries to engage in collective action with book publishers to make e-books as available as possible to US citizens. He wants the DPLA to explore alternative approaches to copyright that preserve authors’ and publishers’ chief profit window but also maximizing a work’s circulation, including the “library license” that would allow public, noncommercial entities (like the DPLA) to have digital access to certain works in copyright after five years, or Knowledge Unlatched, a consortium that purchases in-copyright books for open access. The DPLA also wants to work directly with authors to donate their books to the commons.

Princeton philosopher Peter Singer writes that “scholars have long dreamed of a universal library containing everything that has ever been written.” He calls this a “Library of Utopia” – but agrees with the Digital Public Library of America that a utopia is more than idle fantasy. It is an idea worth striving for; perhaps even a moral imperative.

“If we can put a man on the moon and sequence the human genome, we should be able to devise something close to a universal digital public library. At that point, we will face another moral imperative, one that will be even more difficult to fulfill: expanding internet access beyond the less than 30% of the world’s population that currently has it.”

Our Digital Afterlives

In 02006, Long Now Board Member David Eagleman wrote in Nature:

There is no afterlife, but a version of us lives on nonetheless.

At the beginning of the computer era, people died with passwords in their heads and no one could access their files. When access to these files was critical, companies could grind to a halt. That’s when programmers invented death switches.

With a death switch, the computer prompts you for your password once a week to make sure you are still alive. When you don’t enter your password for some period of time, the computer deduces you are dead, and your passwords are automatically e-mailed to the second-in-command. Individuals began to use death switches to reveal Swiss bank account numbers to their heirs, to get the last word in an argument, and to confess secrets that were unspeakable during a lifetime.

In other words, a “death switch” is a way for us to pre-program an afterlife for our digital selves. Despite the relatively short lifespan of software platforms, it is likely that the data we post on the internet will live on – somewhere – after we ourselves expire.

Eagleman, along with several others, is urging us to think about what will happen to our digital legacy after death: to decide where we want our data to live, and who will have the privilege to engage with it. Do we want to place our legacy in the hands of an heir, or do we want our online presence to be erased? Alternatively, do we perhaps want to designate our own computers as executors of our estate, and have it send out friendly messages to our descendants every once in a while?

Over the past two years, a series of Digital Death Day “unconferences” has brought people together to talk about these kinds of questions. Evan Carroll and John Romano published a book and host an accompanying blog about ways to shape our digital afterlives. And most recently, Google introduced its Inactive Account Manager: a new tool that allows you to decide what will happen to your emails, photo albums, posted videos and personal profiles when your account becomes inactive.

Planning for our digital beyond is a way to save our own lives from receding into a digital dark age – and as such, it may be a way to keep something of ourselves alive after our bodies die. Eagleman muses:

This situation allows us to forever revisit shared jokes, to remedy lost opportunities for a kind word, to recall stories about delightfully earthly experiences that can no longer be felt. Memories now live on their own, and no one forgets them or grows tired of telling them. We are quite satisfied with this arrangement, because reminiscing about our glory days of existence is perhaps all that would have happened in an afterlife anyway.

Danny Hillis: We need a backup internet

Speaking at TED earlier this year, Long Now co-founder Danny Hillis described the early days of networked computing – a time when one could register “” on a whim and everyone with an email address or a domain could be listed in a single book.

He explained that the design of the Internet Protocol and the early community using it were infused with communistic values - ironic, he notes, as the tech grew out of Cold War militarism.

Since then, of course, the internet, its users and its uses have expanded far beyond the wildest dreams of its creators. In so doing, it has become an essential societal infrastructure – without having been designed as such. As another Long Now Board Member, David Eagleman, points out, the internet is not invulnerable. Emergency communications and other high-priority services must be possible without the internet, but increasingly depend on it.

Hillis says a separate backup internet would not be hard to build and would dramatically increase our resilience to disaster and malfeasance.

This year’s TED conference has two of Long Now’s board members presenting, Stewart Brand and Danny Hillis. Although the videos will not be published on the TED site until later this year, some attendees graciously summarized and illustrated the talks for the rest of us. The cartoons below come from Fever Pitch, a group of artists that put information in illustrated form. You can find the rest of their TED illustrations on their Facebook page.


Stewart’s talk introduces the concept of de-extinction to the TED community. First giving an overview of the technology and previous research, he goes on to explain how the newly launched Revive & Restore project is working on bringing back other extinct species, starting with the passenger pigeon. Revive & Restore will be hosting TEDxDeExtinction in Washington DC on March 15th to further explore this project.


The Internet Needs a Plan B

Danny’s talk calls for the creation for a plan B in the case of internet failure. Michael Copeland from Wired also gives a good summary of the key points of the talk for those that were not physically present.

Researchers theorize new method of highly precise atomic timekeeping

Posted on Wednesday, February 6th, 02013 by Charlotte Hajer

Albert Einstein discovered that time is woven into the fabric of space. Now, Berkeley researcher Holger Müller suggests that time is woven into matter, as well.

Interested in determining the simplest possible way of measuring time, Müller has discovered a way to turn matter into a natural clock.

“When I was very young and reading science books, I always wondered why there was so little explanation of what time is,” said Müller, who is also a guest scientist at Lawrence Berkeley National Laboratory. “Since then, I’ve often asked myself, ‘What is the simplest thing that can measure time, the simplest system that feels the passage of time?’ Now we have an upper limit: one single massive particle is enough.”

This is not an atomic clock in the traditional sense; rather than measuring the energy emissions of electrons, Müller’s timekeeper looks at atoms as a whole by making use of a particular feature of matter: its building blocks behave like both particles and waves.

Quantum mechanics was born when physicists decided that light was neither a wave (as argued by Huygens) nor a beam of particles (as Newton thought), but both. In 1924, De Broglie discovered that this duality was true for all forms of matter, and developed a formula to calculate the wavelength of different particles.

Müller theorized that if you can find a way to measure these wavelengths experimentally – if you can construct a clockwork to count an atom’s oscillations – you have a very fundamental unit of time. Unfortunately, these atomic frequencies (also known as Compton frequencies) still outpace our best instruments of detection. But Müller has found a possible solution in yet another one of Einstein’s discoveries. Because motion slows the passage of time, a moving atom oscillates at a slower pace than a stationary one. The difference between the two frequencies may be measurable, and thereby give us a unit of time.

Though Müller’s mechanism is not yet as precise as an atomic clock, improvement of the design will increase its accuracy. Either way, the implications are far-reaching. If matter can be used to count time, the reverse is also true: time can become a unit of measurement for matter. In other words: Müller’s work shows that time is woven into the most fundamental building blocks of our world. One might even say it’s what we’re made of.
