Watch an Accurate Reconstruction of the World’s Oldest Computer, the 2,200 Year-Old Antikythera Mechanism, from Start to Finish

There’s nothing like an ancient mystery, especially one as seemingly insoluble as the origins of “the world’s first computer,” the Antikythera mechanism. Discovered off the coast of the Greek island of Antikythera in 1901, the corroded collection of gears and dials seemed fake to scientists at first because of its ingeniousness. It has since been dated to 100 to 150 BC and has inspired decades of research and speculative reconstruction. Yet, no one knows who made it, and more importantly, no one knows how it was made.

“The distance between this device’s complexity and others made at the same time is infinite,” says Adam Wojcik, a materials scientist at the University College of London. “Frankly, there is nothing like it that has ever been found. It’s out of this world.”

The expression should not make us think of ancient aliens — the Antikythera mechanism contains more than enough evidence of human limitation, showing a geocentric model of the cosmos with the only five planets its maker would have known.

The 2,000-plus year-old device continues to reveal its secrets, including hidden inscriptions found during CT scans of the object, as Smithsonian reported in 2015. The mechanism is “similar in size to a mantel clock, and bits of wood found on the fragments suggest it was housed in a wooden case. Like a clock, the case would’ve had a large circular face with rotating hands. There was a knob or handle on the side, for winding the mechanism forward or backward. And as the knob turned, trains of interlocking gearwheels drove at least seven hands at various speeds. Instead of hours and minutes, the hands displayed celestial time.”

If the Antikythera mechanism is a “celestial clock,” who better to design and build its reconstruction than a clockmaker? That is exactly what we see in the videos above, created for the clockmaking YouTube channel Clickspring. Using the best scientific model of the mechanism to date — published this year by Dr. Tony Freeth and colleagues of the Antikythera Mechanism Research Project — Clickspring shows how the device might have fit together and makes educated guesses about the right placement of its dozens of small parts.

You can see a preview of the Antikythera reconstruction project at the top, watch the full project above, and see individual episodes showcasing different phases of construction on YouTube. The model “conforms to all the physical evidence,” Freeth writes, “and matches the descriptions in the scientific inscriptions engraved on the mechanism itself.” What no one can figure out, however, is just how the ancient Greek artisans who made it shaped precision metal parts without lathes and other modern tools of the machine-makers trade. Researchers, and clockmakers, may have pieced together the Antikythera puzzle, but the mystery of how it came into existence at all remains unsolved.

When Albert Einstein & Charlie Chaplin Met and Became Fast Famous Friends (1930)

Photo via Wikimedia Commons “You do not really understand something unless you can explain it to your grandmother,” goes a well-known quote attributed variously to Albert Einstein, Richard Feynman, and Ernest Rutherford. No matter who said it, “the sentiment… rings true,” writes Michelle Lavery , “for researchers in all disciplines from particle physics to ecopsychology.” As Feynman discovered during his many years of teaching , it could be “the motto of all professional communicators,” The Guardian ’s Russell Grossman writes , “and especially those who earn a living communicating the tricky business of science.” Einstein became one of the world’s great science communicators by choice, not necessity, and found ways to explain his complex theories to children and the elderly alike. But perhaps, if he’d had his way, he would rather have avoided words altogether, and preferred acrobatic feats of silent daring to get his message across. We might at least conclude so from his reverence f...

What Voltaire Meant When He Said That “We Must Cultivate Our Garden”: An Animated Introduction

“Voltaire’s goal in writing [his 1759 satire Candide ] was to destroy the optimism of his times,” says Alain de Botton in the School of Life video above, “an optimism that centered around science, love, technical progress, and a faith in reason.” These beliefs were folly, Voltaire thought: the transfer of faith from a providential God to a perfect, clockwork universe. Candide satirizes this happy rationalism in Doctor Pangloss, whose belief that ours is the best of possible worlds comes directly from the philosophical optimism of Gottfried Leibniz . The preponderance of the evidence, Voltaire made abundantly clear in the novel’s series of increasingly horrific episodes, points toward a blind, indifferent universe full of needless cruelty and chaos. “Hope was, he felt, a disease,” de Botton says, and “it was Voltaire’s generous goal to try and cure us of it.” But as everyone who has read Candide (or read a summary or brief notes on Candide ) knows, the novel does not end with ...

1,100 Delicate Drawings of Root Systems Reveals the Hidden World of Plants

We know that plants can inspire art. If you, personally, still require convincing on that point, just have a look at Elizabeth Twining’s Illustrations of the Natural Orders of Plants , the drawings of Ernst Heinrich Haeckel , Elizabeth Blackwell’s  A Curious Herbal , and Nancy Anne Kingsbury Wollstonecraft’s Specimens of the Plants and Fruits of the Island of Cuba — not to mention the paintings of Georgia O’ Keeffe — all previously featured here on Open Culture. But those works concern themselves only with plant life as it exists above ground. What goes on down below, underneath the soil? That you can see for yourself — and without having to pull up one of our fine flowering (or non-flowering) friends to do so — at Wageningen University’s online archive of root system drawings . “The outcome of 40 years of  root system excavations in Europe,” says that site, the collection contains 1,180 diagrams of species from  Abies alba (best known today as a kind of Christmas t...
