Few human inventions are meant to last hundreds of years, much less thousands. But the 10,000 Year Clock is designed to keep accurate time for millennia. First proposed in 1989, the long-lasting timepiece is finally being installed inside a mountain in western Texas, according to CNET.

The organization building the clock, the Long Now Foundation, wanted to create a tribute to thinking about the future. Founded by computer scientist Danny Hillis and Whole Earth Catalog publisher Stewart Brand, the group boasts famous members like musician Brian Eno and numerous Silicon Valley heavyweights. Amazon founder Jeff Bezos is putting up the $42 million necessary to complete the project, writing that “it's a special Clock, designed to be a symbol, an icon for long-term thinking."

Measuring 500 feet tall when it's completed, the clock will run on thermal power and synchronize each day at solar noon. Every day, a “chime generator” will come up with a different sequence of rings, never repeating a sequence day to day. On specific anniversaries—one year, 10 years, 100 years, 1000 years, 10,000 years—it will animate a mechanical system within one of five rooms carved into the mountain. On the first anniversary, for instance, the clock will animate an orrery, a model of the solar system. Since they don’t expect to be alive for many of the future anniversaries, the clock’s creators won't determine animations for 100, 1000, or 10,000 years—that'll be left up to future generations. (To give you an idea of just how far away 10,000 years is, in 8000 B.C.E., humans had just started to domesticate cows for the first time.)

Though you can sign up to be notified when the clock is finished, it won’t be easy to see it up close. The nearest airport is several hours’ drive away, and the mountain is 2000 feet above the valley floor. So you may have to be content with seeing it virtually in the video below.

10 Electrifying Facts About Michael Faraday

This world-changing genius was born into poverty on September 22, 1791. Fortunately for us, Michael Faraday refused to let his background stand in his way.

1. HE WAS LARGELY SELF-EDUCATED.

In Faraday's boyhood home, money was always tight. His father, James, was a sickly blacksmith who struggled to support a wife and four children in one of London's poorer outskirts. At age 13, young Faraday started helping the family make ends meet. Bookseller George Ribeau (sometimes spelled Riebau) took him on as an errand boy in 1804, with the teen's primary job being the delivery and recovery of loaned-out newspapers.

Shortly after Faraday's 14th birthday, Ribeau offered him a free apprenticeship. Over the next seven years, he mastered the trade of bookbinding. After hours, Faraday remained in Ribeau's store, hungrily reading many of the same volumes he'd bound together.

Like most lower-class boys, Faraday's formal schooling was very limited. Between those bookshelves, however, he taught himself a great deal—especially about chemistry, physics, and a mysterious force called "electricity."

2. A 300-PAGE NOTEBOOK LAUNCHED HIS SCIENTIFIC CAREER.

Sir Humphry Davy (above) left a huge mark on science. In the year 1808 alone, the man discovered no less than five elements, including calcium and boron. An excellent public speaker, Davy's lectures at the Royal Institution consistently drew huge crowds. 

Twenty-year-old Faraday attended four of these presentations in 1812, having received tickets from a customer. As Davy spoke, Faraday jotted down detailed notes, which he then compiled and bound into a little book. Faraday sent his 300-page transcript to Davy. Duly impressed, the seasoned scientist eventually hired him as a lab assistant. Later in life, Davy was asked to name the greatest discovery he'd ever made. His answer: "Michael Faraday."

Tension would nevertheless erupt between mentor and protégé. As Faraday's accomplishments began to eclipse his own, Davy accused the younger man of plagiarizing another scientist's work (this rumor was swiftly discredited) and tried to block his admission to the Royal Society.

3. IF IT WEREN'T FOR FARADAY, WE MIGHT NOT HAVE ELECTRIC POWER.

On September 3, 1821, Faraday built a device that ushered technology into the modern era. One year earlier, Danish physicist Hans Christian Ørsted had demonstrated that when an electric current flows through a wire, a magnetic field is created around it. Faraday capitalized on this revelation. Inside the Royal Society basement, he began what was arguably his most groundbreaking experiment by placing a magnet in the bottom of a mercury-filled glass container. Dangling overhead was a wire, which Faraday connected to a battery. Once an electric current was conducted through the wire, it began rotating around the magnet.

Faraday had just built the world's first electric motor. How could he possibly top himself? By building the world's first electric generator. His first experiment was comprised of a simple ring of wires and cotton through which he passed a magnet. By doing so, he found that a current was generated. To this day, most electricity is made using the same principles.

4. FARADAY INVENTED THE RUBBER BALLOON.

By today's standards, his early models would look shabby. Made via pressing two sheets of rubber together, Faraday's balloons were used to contain hydrogen during his experiments. Faraday created his first in 1824 and was quick to praise the bag's “considerable ascending power.” Toy manufacturers started distributing these the following year.

5. HE'S ALSO THE GRANDFATHER OF MODERN REFRIGERATORS.

In 1823, Faraday sealed a sample of chlorine hydrate inside a V-shaped tube. As he heated one end and cooled the other simultaneously, the scientist noticed that a peculiar yellow liquid was starting to form. Curious, he broke open the tube. Without warning, a sudden, violent explosion sent glass shards flying everywhere. Mercifully uninjured, he smelled a strong scent of chlorine in the air.

It didn't take him very long to figure out what had happened. Inside the tube, pressure was building, which liquefied the gas. Upon puncturing the glass, he'd released this pressure and, afterwards, the liquid reverted into its gaseous state. This sudden evaporation came with an interesting side-effect: it cooled down the surrounding air. Quite unintentionally, Faraday thus set the stage for the very first ice-making machines and refrigeration units.

6. HE BECAME AN ANTI-POLLUTION CRUSADER.

Britain's industrialization came at a malodorous price. As London grew more crowded during the mid-1800s, garbage and fecal matter were dumped into the River Thames with increasing regularity. Naturally, the area didn't smell like a rose. In 1855, Faraday penned an oft-reproduced open letter about the problem, imploring the authorities to take action. “If we neglect this subject,” he wrote, “we cannot expect to do so with impunity; nor ought we be surprised if, ere many years are over, a hot season give us sad proof for the folly of our carelessness.”

Just as Faraday predicted, a broiling summer forced Londoners of all stripes to hold their noses. Dubbed “the Great Stink,” the warmer months of 1858 sent the Thames' rancid odor wafting all over the city. Parliament hastily responded with a comprehensive sewage reform bill. Gradually, the putrid stench began to dissipate.

7. HE STARTED THE ROYAL SOCIETY'S CHRISTMAS LECTURE TRADITION.

Faraday understood the importance of making science accessible to the public. In 1825, while employed by the Royal Society, he spearheaded an annual series that's still going strong today. That holiday season, engineer John Millington delivered a set of layman-friendly lectures on “natural philosophy.” Every year thereafter (excluding 1939–1942 because of WWII), a prominent scientist has been invited to follow in his footsteps. Well-known Christmas lecturers include David Attenborough (1973), Carl Sagan (1977), and Richard Dawkins (1991). Faraday himself was the presenter on no less than 19 occasions.

8. BRILLIANT AS FARADAY WAS, HE STRUGGLED WITH MATH.

Towards the end of his life, Faraday's lack of formal education finally caught up with him. An underprivileged childhood had rendered him mathematically illiterate, a severe handicap for a professional scientist. In 1846, he hypothesized that light itself is an electromagnetic phenomenon, but because Faraday couldn't support the notion with mathematics, it wasn't taken seriously. Salvation for him came in the form of a young physicist named James Clerk Maxwell. Familial wealth had enabled Maxwell to pursue math and—in 1864—he released equations [PDF] that helped prove Faraday's hunch.

9. AS TIME WORE ON, HE STRUGGLED WITH MEMORY LOSS.

At the age of 48, Faraday's once-sharp memory started faltering. Stricken by an illness that rendered him unable to work for three years, he wrestled with vertigo, unsteadiness, and other symptoms. Following this "extended vacation" [PDF], he returned to the Royal Society, where he experimented away until his early 70s.

However, Faraday was still prone to inexplicable spurts of sudden giddiness, depression, and extreme forgetfulness. “[My] bad memory,” he wrote, “both loses recent things and sometimes suggests old ones as new.” Nobody knows what caused this affliction, though some blame it on overexposure to mercury.

10. EINSTEIN KEPT A PORTRAIT OF FARADAY IN HIS BERLIN HOME.

Fittingly, the father of modern physics regarded Faraday as a personal hero. Once, upon receiving a book about him, Einstein remarked, “This man loved mysterious Nature as a lover loves his distant beloved.”

This Amateur Rocketeer Builds Functioning, Miniature Replicas of SpaceX Rockets

Amateur rocketry is a hobby that predates NASA. Hobbyists have successfully made it to space using rockets built without the massive budgets and resources available to larger organizations. And some of these rockets do more than reach incredible heights: As Motherboard reports, Joe Barnard, a 25-year-old rocketeer from Nashville, Tennessee, is working on making model rockets capable of propulsive landings, the same trick that makes some SpaceX rockets reusable.

Most rocket boosters that propel loads past the Earth's atmosphere are designed to go only one way. In 2015, Elon Musk's space exploration company SpaceX made history when it successfully maneuvered the boosters used to launch its Falcon 9 rocket back onto the landing pad. SpaceX says its latest version of the rocket can be re-flown up to 100 times, saving the company millions of dollars per launch.

Joe Barnard is bringing this same level of innovation to the amateur rocketry world. He first became interested in aerospace engineering after watching early SpaceX videos, and instead of earning a degree in the field, he taught himself the basics. He's since made rocketry into a career, founding Barnard Propulsion Systems (BPS), a small business that sells supplies to other hobbyists, and working on rockets of his own.

Like the rockets at SpaceX, Barnard's creations use thrust vectoring—the technology that makes it possible to navigate and stabilize a rocket after launch—only on a much smaller scale. He's built miniature models of SpaceX's Falcon 9 rockets, and as is the case at SpaceX, his launches don't always run smoothly.

Barnard is still perfecting propulsive landings in amateur rockets, but for now he says each failure is a learning experience. You can watch the progress of his experiments on his YouTube channel.
