Alexander Rose: Designing for Longevity
Building The 10,000 Year Clock
Tuesday October 28, 02014 at 7:30pm
at The Interval (check-in at 6:30)
Advanced Tickets recommended

Late in the last millennium, Danny Hillis told a small group of friends about his idea for building a monument-scale clock that would last for 10,000 years. The group included Stewart Brand, Kevin Kelly, and Brian Eno – and the conversations that followed led to the founding of The Long Now Foundation in 01996. Ever since then, Long Now has worked to bring the Clock into reality.

Alexander Rose has been there almost from the start. The first employee of Long Now, he assisted Danny Hillis in early design work. Now he is the Foundation’s Executive Director and serves as the project manager for the full-sized Clock construction which is now underway in Texas. In his talk at The Interval he will discuss both the beginnings of the Clock project and where we are today.

The Clock has been built slowly, methodically, with a dedication to doing it right for the long term. And without a short-term deadline. The design process has been slow and painstaking. Our prototypes are built from the highest-quality materials and feature hand-crafted custom work. Our durability testing approximates the wear of slow moving mechanisms running for thousands of years.

Tickets are still available but space is limited and this talk will sell out

This talk will also include the lessons that Long Now’s team has learned from studying these previous millennial design projects. Alexander has travelled the world researching other projects designed to last for a thousand years or more. These include the Svalbard Global Seed Vault, the Granite Mountain Records Vault built by the Mormon Church, and most recently Ise Grand Shrine in Japan.

Long Now’s Orrery Prototype For The 10,000 Year Clock

The Long Now's Orrery prototype

One of the first things that visitors see when they walk into The Interval, Long Now’s new public space, is the Orrery–a prototype for part of the 10,000 Year Clock now under construction. The Orrery is a simplified mechanical model of our solar system, a precise and durable computer, and an eight-foot-tall kinetic sculpture.

This is our 21st century interpretation of an ancient device: the first record of a planetary model dates back two millennia. While the modern design, the direct ancestor of Long Now’s Orrery, was first built in England three centuries ago.

The Orrery at The Interval

Our Orrery’s display features the six planets that can be seen with the naked eye (Mercury through Saturn). The “bit adder” gears below the planetary display each drives a planet. The prototype is designed to update each planet’s position twice a day, so this model of the solar system can show their positions in orbit around the Sun accurately.

A kinetic sculpture of the Long Now: Mercury completes one revolution in about 88 days; the Earth takes exactly one solar year; Saturn makes it around the Sun in just under thirty years. So in the time since this prototype was first completed in 02005, Saturn would have traveled only a third of its year.

Each of the Orrery’s planets is ground from a stone that resembles the actual celestial body:

  • Sun: Yellow Calcite
  • Mercury: Meteorite
  • Venus: Lemon Yellow Mexican Calcite
  • Earth: Chilean Lapis
  • Mars: Red Namibian Jasper
  • Jupiter: Banded Sandstone
  • Saturn: Banded Utah Onyx

Because we can look back and see that the way time has been measured throughout history has changed, it’s reasonable to imagine when looking forward that it will continue to change – our current use of hours, minutes, weeks and months may be as obscure and forgotten as the nundina, the akhet, or the gesh several millennia from now. The day, the year, and the movements of the other planets in our solar system, on the other hand, aren’t at the whim of the powers that be or of passing cultural trends. The 10,000 Year Clock, therefore, keeps track of these robust and durable units of time. The Clock’s main dial keeps track of the Sun, Moon and stars while The Orrery models our solar system.

Also robust and durable is The Orrery’s mechanical system for calculating the planets’ movements. A large and complicated gear system could do the job, but would wear down and lose accuracy over the millennia. To avoid this problem, Danny Hillis invented a device called a serial bit adder – a simple mechanical binary computer. The bit adders calculate how much to move the planets in the display based on the known input of two rotations per day by the Orrery’s central shaft. As that shaft rotates it also turns the 6 bit adder disks: one for each planet.

A bit adder consists of a rotating disk and two sets of 27mechanical pins. Each individual pin can be in one of two states and each set of pins taken altogether represents a 27 bit number. One set of pins is immovable – these are set based on the calculation that particular bit adder must perform; they are the program. The other set of pins can move between the two possible states; they represent an accumulator.

As the bit adder’s disk rotates, a portion of the disk reads the program from the unmoving bits and is moved by them. Its movements cause the other set of bits to be flipped as necessary. Each time the adder rotates, it adds the number encoded in the static pins into the number encoded by the moveable ones. That number is a fraction between zero and one. As the outer pins accumulate the value represented by the inner pins, their value grows towards one. When they surpass a value of one, the adder produces an output that adjusts its corresponding planet by way of engaging a 6-sided Geneva wheel. In this way, a precise ratio can be calculated based on the two daily rotations of the central shaft and applied to the planets in the display.

The crucial mathematical logic for the bit adders is represented in the positions of the pins, which can only ever be in one of two states even if they become significantly worn. This is a digital representation. Most traditional clocks, on the other hand, perform their mathematics in the orientation of gears around an axis. A gear measured this way can be in an infinite number of states. This is an analog representation. As the gear’s teeth become worn, its position can shift and slip, allowing inaccuracy to build up within the system over long periods of time.

The Orrery was conceptualized by Danny Hillis, with project management and additional design by Alexander Rose. Lead engineer was Paolo Salvagione, and lead machinist and fabricator was Christopher Rand. Other machinists include Erio Brown, Brian Roe, Mark Ribaud, Reason Bradley, General Precision, Oakland Machine Works, Jim Johnson, Brian Ford, Ebin Stromquist, and the base was fabricated by Seattle Solstice.

Almost a decade after its completion, the Orrery has become an iconic image for Long Now and a fixture of our public space. Many first visit The Interval because they notice the unusual 8-foot tall structure through our window, and they have to know more. For Long Now members and staff it’s an inspiring reminder of the full-scale Clock, whose Orrery will be four times the size of our prototype. In the future the Sun and six planets may be the first clue to a visitor to the Clock site as to the nature of the device they’ve just discovered.

And others are inspired to reproduce the Orrery themselves:

In October 02008 Edward Burtynsky spoke for Long Now on The 10,000-year Gallery. Burtynsky, an internationally-recognized photographer, presented his ideas for a gallery of images to accompany the Clock of the Long Now.

Twice a month we highlight a Seminar About Long-term Thinking (SALT) from our archives. Long Now members can watch this Seminar video here, and this talk is even better with the visuals.

SALT audio is free for everyone on our Seminar pages and via podcast. Long Now members can see all Seminar videos in HD. Video of the 12 most recent Seminars is also free for all to view.

Burtynsky’s The 10,000-year Gallery talk includes a formal proposal for a permanent art gallery in the chamber that encloses the 10,000-year Clock as well as the results of his research into methods of capturing images that might have the best chance to survive in the long-term.

Photographer Edward Burtynsky

From Stewart Brand’s summary of this Seminar (in full here):

On the stage Burtynsky showed a large carbon transfer print of one of his ultra-high resolution photographs. The color and detail were perfect. Accelerated studies show that the print could hang in someone’s living room for 500 years and show no loss of quality. Kept in the Clock’s mountain in archival conditions it would remain unchanged for 10,000 years. He said that making one print takes five days of work, costs $2,000, and only ten artisans in the world have the skill, at locations in Toronto, Seattle, and Cornwall.

Edward Burtynsky‘s photographs are collected in museums all over the world. He is known for his large-format photographs of industrial landscapes which include mining locations around the globe and the building of Three Gorges Dam in China. His work has been noted for beautiful images which are often at odds with their subject’s negative environmental impacts. In recent years his work has focused on water including oil spills around the world.

The Seminars About Long-term Thinking series began in 02003 and is presented each month live in San Francisco. The series is curated and hosted by Long Now’s President Stewart Brand. Seminar audio is available to all via podcast.

Long Now members can watch the full video of this Seminar here—you must be logged in to the site. Membership levels start at $8/month and include lots of benefits. Join Long Now today.

Long Now intro – sound by Brian Eno

Today we’re debuting a 10-second animated Long Now intro that will soon be seen at the start of all Long Now videos and clips. It’s a brief glimpse into parts of The 10,000 Year Clock in virtual form as you watch 20,000 years tick by. Sometimes the long-term can be contemplated in small increments…

It features sound by Brian Eno that uses recordings of the 10,000 Year Clock (in progress) and visuals taken directly from the clock design as well.

This intro video was conceived by Alexander Rose, James Anderson and Chris Baldwin. The sound is by Brian Eno with additional recordings and arrangement by Chris Baldwin which includes sounds from the workings of the 10,000 Year Clock. The animation was created by James Anderson using actual model geometry of parts used in the Clock. The animation is © The Long Now Foundation 02013 and the sound is © Opal Ltd., London 02013.

We hope it is enjoyed by everyone who already knows about the Clock and will be a compelling clue for others to want to learn more. Thanks to James, Chris, Brian and everyone else who contributed to making this well-crafted representation of The Long Now Foundation.

Last week we announced that Brian Eno is designing the ambient sound for the Long Now Salon as well as a dedicated light-painting installation for the space.

Brian is a founding member of Long Now’s Board of Directors.

ThePresent from m ss ng p eces on Vimeo.

The Present is a clock with an annual dial that was funded originally through Kickstarter by design collective m ss ng p eces. The inspiration for this clock seems to come from a similar place as the Clock of the Long Now.

This was one of those early blockbuster Kickstarter projects that reached 4x its fund raising goal. After a couple years figuring out how to produce these as a product, it has finally shipped and we just received ours. It has excellent build quality from what I can tell and auto-magically sets itself as soon as you put batteries into it.  Since we are only a few days away from the March Equinox ours moved directly to nearly the “3 o’clock” position in the middle of the green section (see pic below).  As we approach summer the hand will move into yellow, then reds for autumn etc.

One of the early ideas for the 10,000 Year Clock was to simply endow a family whose job it would be for 400 generations to just shout out the time every day.  I had no idea there was already someone like that… RIP John Votta.

“The Washington Square timekeeper was a link back to a very ancient tradition of people who both tell time and look out for the public good,”

YES Watch Father’s Day Sale

Long Now’s 10,000 Year Clock will tell time not in hours and minutes, but by keeping track of the astronomical cycles underlying those units. We can’t predict how the calendar and timing systems will change over the next 10,000 years, but we know they’re likely to be built on top of the very same things we’ve built our system on: the rotation of the earth, the cycles of the moon, and the ebb and flow of light and dark throughout the years’ seasons. For most of human history, time wasn’t  a matter of digits ticking by, but rather a complex interplay of these overlapping rhythms.

The makers of YES watches seem to similarly appreciate this long-view of time-keeping. Into thoroughly modern digital timepieces with all the standard functionality you’d expect in a digital watch, they’ve incorporated a taste of our deep history with the sky. YES watches feature an analogue hour hand that rotates once each day, indicating along its way the rising and setting of the sun and moon.

It’s because of this resonance that we’ve carried them for years now in our Museum & Store in San Francisco, but between now and Father’s Day, Yes is also giving Long Now a 20% commission on each watch bought online through this link: www.yeswatch.com/longnow For Father’s Day, they’ve created a new style of watch with two 24-hour bezels.

Bjorn Kartomten is the brains behind this innovative design. He worked with a global team of manufacturers to realize his idea of making a watch that tells modern time along side the cycles of the sun and moon. The hand movement is made in Switzerland, the sapphire crystal in Germany and the chip is made in Japan. The Yes Watches are used by film directors, photographers, adventurers and more – anyone who would like to to have an accurate understanding of the day and night’s natural cycles.

Time in the 10,000-Year Clock

Keeping time for 10,000 years isn’t tricky just because its hard to build a really durable clock. It also forces us to recognize and account for changes in things we normally think of as immutable, like the length of a day.

Long Now co-founder and lead designer of the 10,000-Year Clock, Danny Hillis, published a paper recently along with Rob Seaman, Steve Allen, and Jon Giorgini, with the American Astronomical Society.  The paper discusses the different kinds of time that the Clock needs to track in order to show accurate time for the next ten millennia, and how these systems interrelate.

The 10,000-Year Clock has both a pendulum (generating an approximation of absolute time) and is also synchronized to the sun at noon. Therefore the Clock must reconcile Universal Time, Terrestrial Time, and Barycentric Dynamical Time and also deal with unpredictable changes in the Earth’s rotation:

“The variation is caused by a variety of effects including tidal drags, shifts in the Earth’s crust, changes in ocean levels, and even weather… This creates an uncertainty in the average length of day of about 10 parts per million, an uncertainty of plus or minus 37 solar days over the design lifetime of the clock.”

So, not accounting for these variations could theoretically leave the Clock over a month off at the end of 10,000 years. Read the paper to see how each system is accounted for.

The paper was presented at a colloquium in October 02011 called Decoupling Civil Timekeeping from Earth Rotation. Attendees, including astrophysicist Neil deGrasse Tyson, discussed the paper and the 10,000-Year Clock. Notes taken during the conversation show that, while the technical success of the Clock’s durability is yet to be determined, its ability to inspire long-term thinking is already taking hold:

Neil deGrasse Tyson jested that the Long Now should put some signage on the 10,000 Year Clock so that a post-apocalyptic Earth will not think that the world will end when the clock stops working.

Clock Project Update from Jeff Bezos

Below is the Clock Project update by Jeff Bezos published at http://www.10000yearclock.net

Quick Update and Video of the Raise Bore Milestone

We just completed the 12½ foot diameter, 500 foot deep vertical shaft for the 10,000 Year Clock. We used a mining technique called raise boring. Take a look at the video – it’s an interesting operation. Instead of drilling down from the top, you pull a large diameter reamer up to the surface from the bottom using a smaller diameter pilot hole – more efficient than a top-down drill because the rubble isn’t fighting gravity. It rains down beneath the advancing bore and gets hauled out a horizontal shaft at the bottom. Our next major step will be cutting the spiral stairway using a robotic stone cutting saw. In parallel, we’re also manufacturing and testing the Clock components.

The Clock team continues to do an impressive and amazing job – they are organized and ingenious. Extra special thanks to Danny Hillis and Alexander Rose who deserve big kudos for driving to this key milestone. Big thanks as well to Swaggart Brothers, Cementation, and Geomagic, all of which played a crucial role. I encourage and invite you to become a member of The Long Now Foundation, the non-profit that was founded to foster long-term thinking and has focused tremendous energy on the Clock, as well as other noteworthy projects. You can visit their website to learn more and become a member.

Many thanks for your interest in the Clock and in the long view!
