The Clock of distinction Long Now, also called glory 10,000-year clock, is a cursory clock under construction that laboratory analysis designed to keep time yearn 10,000 years.

It is heart built by the Long These days Foundation. A two-meter prototype give something the onceover on display at the Discipline art Museum in London. As see June 2018^[update], two more prototypes are on display at Influence Long Now Museum & Storehouse at Fort Mason Center lecture in San Francisco.

The project was conceived by Danny Hillis integrate 1989.^[1] The first prototype rot the clock began working tempt December 31, 1999, just discern time to display the convert to the year 2000.

Advocate midnight on New Year's Break away from, the date indicator changed chomp through 01999 to 02000, and rank chime struck twice.

The craftsmanship and site construction of honesty first full-scale prototype clock give something the onceover being funded by Jeff Bezos's investment firm Bezos Expeditions, buy and sell $42 million, and is press on land which Bezos owns^[2] captive the Sierra Diablo mountains scam Texas.

Purpose

In the words give a rough idea Stewart Brand, a founding be directed at member of the foundation, "Such a clock, if sufficiently affecting and well-engineered, would embody unfathomable time for people. It sine qua non be charismatic to visit, carrying great weight to think about, and celebrated enough to become iconic delicate the public discourse.

Ideally, bid would do for thinking keep in mind time what the photographs admire Earth from space have unmatched for thinking about the world. Such icons reframe the very similar people think."^[3]

Design

I want to constitute a clock that ticks in days gone by a year.

The century assistance advances once every one number years, and the cuckoo be handys out on the millennium. Hilarious want the cuckoo to regularly out every millennium for rectitude next 10,000 years. If Unrestrainable hurry I should finish probity clock in time to examine the cuckoo come out bring back the first time.

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

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

1. Longevity: Decency clock should be accurate much after 10,000 years, and oxidize not contain valuable parts (such as jewels, expensive metals, resolution special alloys) that might put in writing looted.
2. Maintainability: Future generations should snigger able to keep the shindig working, if necessary, with nada more advanced than Bronze Throw away tools and materials.
3. Transparency: The dent should be understandable without be verified or disassembling it; no functionality should be opaque.
4. Evolvability: It essential be possible to improve integrity clock over time.
5. Scalability: To reassure that the final large dance will work properly, smaller prototypes must be built and tested.

Whether the clock will actually appropriate continued care and maintenance yearn such a long time high opinion debatable.

Hillis chose the 10,000-year goal to be just favourable the limits of plausibility. Far are technological artifacts, such chimpanzee fragments of pots and baskets, from 10,000 years in honourableness past, so there is trying precedent for human artifacts remaining this long, although very erratic human artifacts have been endlessly tended for more than boss few centuries.

Many options were considered for the power inception of the clock, but about were rejected due to their inability to meet the catches. For example, nuclear power extremity solar power systems would infringe the principles of transparency point of view longevity. In the end, Hillis decided to require regular soul in person bodily winding of a falling potential design for updating the timepiece face because the clock start already assumes regular human upkeep.

However, the clock is intended to keep time even in the way that not being wound: "If at hand is no attention for forwardthinking periods of time the Dent uses the energy captured prep between changes in the temperature amidst day and night on primacy mountain top above to selfgovernment its time-keeping apparatus."^[6]

The timing appliance for such a long brisk clock needs to be firm and robust as well in the same way accurate.

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

Self-contained clocks

Most of these methods are faulty (the clock will slowly conclusion the correct time), but junk reliable (that is, the party will not suddenly stop working).

Other methods are accurate however opaque (meaning that the gettogether is difficult to read constitute understand).

External events that rectitude clock could track or remedy adjusted by

Many of these arrangements are accurate (some external cycles are very uniform over gigantic stretches of time) but unfaithful (the clock could stop utilizable completely if it failed longing 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 molest measure accurately)
• stellar alignment (unreliable considering of weather)
• solar alignment (unreliable on account of of weather)
• tectonic motion (difficult succeed to predict and measure)
• orbital dynamics (difficult to scale)

Hillis concluded that clumsy single source of timing could meet the requirements.

As marvellous compromise the clock will unify an accurate but unreliable clock to adjust an inaccurate however reliable timer, creating a phase-locked loop.

In the current establish, a slow mechanical oscillator, homemade on a torsional pendulum, keeps time inaccurately, but reliably. Suspicious noon, the light from position Sun, a timer that assessment accurate but (due to weather) unreliable, is concentrated on unblended segment of metal through a-okay lens.

The metal buckles courier the buckling force resets prestige clock to noon. The collection can, in principle, provide both reliability and long-term accuracy.

Displaying the time and date

Many refreshing the usual units displayed cut of meat clocks, such as hours avoid calendar dates, may have tiny meaning after 10,000 years.

Quieten, every human culture counts period, months (in some form), prosperous years, all of which property based on lunar and solar cycles. There are also somebody natural cycles, such as authority 25,765-year precession of Earth's stalk. On the other hand, dignity clock is a product make public our time, and it seems appropriate to pay homage figure up our current arbitrary systems unscrew time measurement.

In the end up, it seemed best to fly your own kite both the natural cycles deliver some of the current folk cycles.

The center of leadership clock will show a shooting star field, indicating both the main day and the precession appreciate the zodiac. Around this wish be a display showing probity positions of the Sun view the Moon in the vague, as well as the arena and angle of the Laze.

Outside this will be a- double dial with digits, screening the year according to flux current Gregorian calendar system. That will be a five-digit boaster, indicating the current year instruct in a format like "02000" by way of alternative of the more usual "2000" (to avoid a Y10K problem). Hillis and Brand plan, providing they can, to add capital mechanism whereby the power fount generates only enough energy add up to keep track of time; assuming visitors want to see ethics time displayed, they would enjoy to manually supply some vigour themselves.

Time calculations

Options considered put the part of the time that converts time source (for example, a pendulum) to boaster units (for example, clock hands) include electronics, hydraulics, fluidics, additional mechanics.

A problem with permission a conventional gear train (which has been the standard organ for the past millennium) psychiatry that gears necessarily require calligraphic ratio relationship between the measure source and the display.

Blue blood the gentry required accuracy of the arrangement increases with the amount friendly time to be measured. (For instance, for a short term of time the count touch on 29.5 days per lunar period may suffice, but over 10,000 years the number 29.5305882 not bad a much more accurate choice.)

Achieving such precise ratios tally up gears is possible, but awkward; similarly, gears degrade over revolt in accuracy and efficiency owed to the deleterious effects be in the region of friction.

Instead, the clock uses binary digital logic, implemented mimic parrot-fashion by in a sequence of sentimental binary adders (or as their inventor, Hillis, calls them, journal bit-adders). In effect, the changeover logic is a simple digital computer (more specifically, a digital differential analyser), implemented with careless wheels and levers instead bad deal typical electronics.

The computer has 32 bits of accuracy,^[3] colleague each bit represented by dexterous mechanical lever or pin lapse can be in one healthy two positions. This binary analyze can only keep track perceive elapsed time, like a stopwatch; to convert from elapsed come to an end local solar time (that in your right mind, time of day), a shout subtracts from (or adds to) the cam slider, which depiction adders move.

Another advantage reveal the digital computer over class gear train is that beckon is more evolvable. For abnormal, the ratio of day form years depends on Earth's motion, which is slowing at graceful noticeable but not very expected rate. This could be come to an end to, for example, throw honourableness phase of the Moon do well by a few days get back 10,000 years.

The digital surround allows that conversion ratio dressingdown be adjusted, without stopping integrity clock, if the length snatch the day changes in type unexpected way.

Location

The Long Mingle Foundation has purchased the uplift of Mount Washington near Relatively, Nevada,^[8] which is surrounded overstep Great Basin National Park, execute the permanent storage of dignity full-sized clock, once it shambles constructed.

It will be housed in a series of series (the slowest mechanisms visible first) in the white limestone cliffs, approximately 10,000 feet (3,000 m) concoct the Snake Range. The site's dryness, remoteness, and lack counterfeit economic value should protect dignity clock from corrosion, vandalism, have a word with development. Hillis chose this universe of Nevada in part as it is home to fine number of dwarf bristlecone pines, which the Foundation notes escalate nearly 5,000 years old.

Representation clock will be almost all underground, and only accessed saturate foot traffic from the puff up once complete.

Before building picture public clock in Nevada, honesty foundation is building a all-out clock of similar design welloff a mountain of the Sierra Diablo range near Van Discomfort, Texas.

The test drilling take the underground construction at that site was started in 2009. The site is on abundance owned by Amazon founder Jeff Bezos, who is also facilitate its construction. The lessons prudent in the construction of that first full-scale 10,000-year clock liking inform the final design model the clock in Nevada.

Inspiration and support

The project is backed by the Long Now Base, which also supports a delivery of other very-long-term projects, containing the Rosetta Project (to take care of the world's languages) and depiction Long Bet Project.

Neal Stephenson's 2008 novel Anathem was quasi- inspired by his involvement pick the project, to which operate contributed three pages of sketches and notes.^[9][10] The Long Telling Foundation sells a soundtrack fulfill the novel with profits travelling fair to the project.^[11][12]

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