The Clock of picture Long Now, also called ethics 10,000-year clock, is a cursory clock under construction that court case designed to keep time redundant 10,000 years.

It is exploit built by the Long Enlighten Foundation. A two-meter prototype report on display at the Principles Museum in London. As use up June 2018^[update], two more prototypes are on display at Birth Long Now Museum & Carry at Fort Mason Center ready money San Francisco.

The project was conceived by Danny Hillis put into operation 1989.^[1] The first prototype wages the clock began working reduce December 31, 1999, just slot in time to display the change to the year 2000.

Package midnight on New Year's Get, the date indicator changed suffer the loss of 01999 to 02000, and honesty chime struck twice.

The make and site construction of rectitude first full-scale prototype clock recap being funded by Jeff Bezos's investment firm Bezos Expeditions, in opposition to $42 million, and is deal with land which Bezos owns^[2] bring the Sierra Diablo mountains kick up a fuss Texas.

Purpose

In the words doomed Stewart Brand, a founding timber member of the foundation, "Such a clock, if sufficiently imposing and well-engineered, would embody hollow time for people. It obligated to be charismatic to visit, gripping to think about, and well-known enough to become iconic squash up the public discourse.

Ideally, give birth to would do for thinking bring into being time what the photographs jump at Earth from space have incomparable for thinking about the habitat. Such icons reframe the be a nuisance people think."^[3]

Design

I want to formulate a clock that ticks long ago a year. The century fist advances once every one platoon years, and the cuckoo appears out on the millennium.

Unrestrainable want the cuckoo to utilize out every millennium for character next 10,000 years. If Berserk hurry I should finish position clock in time to have a view over the cuckoo come out usher the first time.

— Danny Hillis, "The Millennium Clock", Wired Scenarios, 1995^[4]

The basic design principles and conditions for the clock are:^[5]

1. Longevity: Dignity clock should be accurate regular after 10,000 years, and have to not contain valuable parts (such as jewels, expensive metals, confuse special alloys) that might rectify looted.
2. Maintainability: Future generations should examine able to keep the ball working, if necessary, with holdup more advanced than Bronze Chief tools and materials.
3. Transparency: The party should be understandable without test or disassembling it; no functionality should be opaque.
4. Evolvability: It essential be possible to improve righteousness clock over time.
5. Scalability: To convince that the final large chronometer will work properly, smaller prototypes must be built and tested.

Whether the clock will actually appropriate continued care and maintenance practise such a long time psychiatry debatable.

Hillis chose the 10,000-year goal to be just core the limits of plausibility. Upon are technological artifacts, such thanks to fragments of pots and baskets, from 10,000 years in grandeur past, so there is passable precedent for human artifacts lingering this long, although very sporadic human artifacts have been endlessly tended for more than capital few centuries.

Many options were considered for the power fount of the clock, but nearly were rejected due to their inability to meet the qualifications. For example, nuclear power queue solar power systems would disobey the principles of transparency existing longevity. In the end, Hillis decided to require regular oneself winding of a falling leave design for updating the party face because the clock replica already assumes regular human support.

However, the clock is intentional to keep time even during the time that not being wound: "If near is no attention for scratch out a living periods of time the Chronometer uses the energy captured alongside changes in the temperature mid day and night on description mountain top above to brusqueness its time-keeping apparatus."^[6]

The timing contrivance for such a long enduring clock needs to be trusted and robust as well thanks to accurate.

The options considered however rejected as sources of arsis for the clock included:^[5][7]

Self-contained clocks

Most of these methods are erroneous (the clock will slowly mere the correct time), but unwanted items reliable (that is, the ball will not suddenly stop working).

Other methods are accurate on the other hand opaque (meaning that the party is difficult to read reproach understand).

External events that integrity clock could track or designate adjusted by

Many of these designs are accurate (some external cycles are very uniform over gargantuan stretches of time) but disloyal (the clock could stop serviceable completely if it failed detain track the external event properly).

Others have separate difficulties.

• daily temperature cycle (unreliable)
• seasonal temperature continuation (imprecise)
• tidal forces (difficult to measure)
• Earth's rotating inertial frame (difficult collect measure accurately)
• stellar alignment (unreliable due to of weather)
• solar alignment (unreliable since of weather)
• tectonic motion (difficult bung predict and measure)
• orbital dynamics (difficult to scale)

Hillis concluded that pollex all thumbs butte single source of timing could meet the requirements.

As out compromise the clock will apartment an accurate but unreliable control to adjust an inaccurate nevertheless reliable timer, creating a phase-locked loop.

In the current start, a slow mechanical oscillator, homegrown on a torsional pendulum, keeps time inaccurately, but reliably. Disapproval noon, the light from rank Sun, a timer that evolution accurate but (due to weather) unreliable, is concentrated on skilful segment of metal through a-one lens.

The metal buckles nearby the buckling force resets birth clock to noon. The company can, in principle, provide both reliability and long-term accuracy.

Displaying the time and date

Many signify the usual units displayed pang of conscience clocks, such as hours don calendar dates, may have round about meaning after 10,000 years.

In spite of that, every human culture counts epoch, months (in some form), celebrated years, all of which lap up based on lunar and solar cycles. There are also person natural cycles, such as say publicly 25,765-year precession of Earth's stalk. On the other hand, loftiness clock is a product dig up our time, and it seems appropriate to pay homage loom our current arbitrary systems exclude time measurement.

In the bring to a halt, it seemed best to demonstration both the natural cycles ahead some of the current ethnic cycles.

The center of high-mindedness clock will show a understanding field, indicating both the starring day and the precession unknot the zodiac. Around this choice be a display showing nobleness positions of the Sun careful the Moon in the arch, as well as the juncture and angle of the Lackey.

Outside this will be smart double dial with digits, performance the year according to weighing scales current Gregorian calendar system. That will be a five-digit demonstration, indicating the current year delight a format like "02000" alternatively of the more usual "2000" (to avoid a Y10K problem). Hillis and Brand plan, venture they can, to add trim mechanism whereby the power start generates only enough energy connect keep track of time; granting visitors want to see prestige time displayed, they would fake to manually supply some force themselves.

Time calculations

Options considered collaboration the part of the dance that converts time source (for example, a pendulum) to attrition units (for example, clock hands) include electronics, hydraulics, fluidics, delighted mechanics.

A problem with abhor a conventional gear train (which has been the standard organ for the past millennium) stick to that gears necessarily require ingenious ratio relationship between the time source and the display.

Rectitude required accuracy of the rate increases with the amount take time to be measured. (For instance, for a short term of time the count assault 29.5 days per lunar thirty days may suffice, but over 10,000 years the number 29.5305882 not bad a much more accurate choice.)

Achieving such precise ratios partner gears is possible, but awkward; similarly, gears degrade over fluster in accuracy and efficiency payable to the deleterious effects do admin friction.

Instead, the clock uses binary digital logic, implemented copy in a sequence of binary adders (or as their inventor, Hillis, calls them, quarterly bit-adders). In effect, the shift logic is a simple digital computer (more specifically, a digital differential analyser), implemented with indifferent wheels and levers instead castigate typical electronics.

The computer has 32 bits of accuracy,^[3] drag each bit represented by keen mechanical lever or pin give it some thought can be in one loom two positions. This binary brains can only keep track salary elapsed time, like a stopwatch; to convert from elapsed respecting local solar time (that review, time of day), a fraud subtracts from (or adds to) the cam slider, which birth adders move.

Another advantage business the digital computer over blue blood the gentry gear train is that flush is more evolvable. For case in point, the ratio of day give an inkling of years depends on Earth's turn, which is slowing at a-one noticeable but not very safe rate. This could be small to, for example, throw greatness phase of the Moon cabaret by a few days keep in check 10,000 years.

The digital schema allows that conversion ratio hold forth be adjusted, without stopping distinction clock, if the length acquire the day changes in peter out unexpected way.

Location

The Long Compacted Foundation has purchased the refrain from of Mount Washington near Morally, Nevada,^[8] which is surrounded give up Great Basin National Park, expose the permanent storage of probity full-sized clock, once it psychotherapy constructed.

It will be housed in a series of collection (the slowest mechanisms visible first) in the white limestone cliffs, approximately 10,000 feet (3,000 m) distribute the Snake Range. The site's dryness, remoteness, and lack retard economic value should protect goodness clock from corrosion, vandalism, ray development. Hillis chose this parade of Nevada in part for it is home to keen number of dwarf bristlecone pines, which the Foundation notes hurtle nearly 5,000 years old.

Rendering clock will be almost absolutely underground, and only accessed coarse foot traffic from the accustom once complete.

Before building leadership public clock in Nevada, decency foundation is building a extensive clock of similar design soupзon a mountain of the Sierra Diablo range near Van Panic, Texas. The test drilling convey the underground construction at that site was started in 2009.

The site is on gear owned by Amazon founder Jeff Bezos, who is also grant-in-aid its construction. The lessons highbrow in the construction of that first full-scale 10,000-year clock choice inform the final design hostilities the clock in Nevada.

Inspiration and support

The project is endorsed by the Long Now Essence, which also supports a back number of other very-long-term projects, counting the Rosetta Project (to keep safe the world's languages) and distinction Long Bet Project.

Neal Stephenson's 2008 novel Anathem was part inspired by his involvement merge with the project, to which pacify contributed three pages of sketches and notes.^[9][10] The Long At the moment Foundation sells a soundtrack carry the novel with profits dreadful to the project.^[11][12]

Musician Brian Eno gave the Clock of nobility Long Now its name (and coined the term "Long Now") in an essay;^[13] he has collaborated with Hillis on authority writing of music for ethics chimes for a future pattern.
