“The hardest thing to hide is something that is not there”*…

 

An ancient city made of intricately carved stone sits silent at the bottom of a lake, a replica of Paris complete with an Eiffel Tower is eerily empty, and a city leveled by disaster has been cordoned off indefinitely as a memorial to those who were lost. China might just be home to more ghost cities than any other nation on earth, and most of them are of the modern variety, as the push for economic progress has led developers to get a bit ahead of themselves constructing vast communities, malls and amusement parks that never caught on with the public…

As we listen for an echo, we might recall that it was on this date in 960 that Zhao Kuangyin became Emperor Taizu of Song– the first ruler of the Song Dynasty, a period of Chinese history that lasted more than three centuries.  A distinguished military leader under the Later Zhou Dynasty, Zhao came to power via a coup d’état that forced the young Emperor Gong to abdicate.  During his reign, Zhao reunified most of China proper, effectively ending the chaotic Five Dynasties and Ten Kingdoms period.

Leggo my Lego…

Readers will recall The Antikythera Mechanism (“A Connecticut Yankee in King Agamemnon’s Court?…“), the oldest known scientific computer, which was built in Greece probably around 100 BCE.   It was recovered from a shipwreck in 1900; but its purpose remained a mystery for over a century, until archeologists and scientists realized its ingenious intent: it’s an extraordinarily-accurate astronomical clock that determines the positions of celestial bodies– an analog computer with over 100 gears and 7 differential gearboxes– accurate to a day or two over its range.

Andrew Carol has rebuilt the device…  in Lego:

Read the story and see photos here.   And for extra fun, check out Carol’s Lego homage to Charles Babbage’s Difference Engine.  As he says of his work,

Having always loved complex mechanical devices, and never having fully outgrown LEGO, I decided to explore where computational mechanics and LEGO meet. This is not LEGO as toy, art, or even the MindStorms® fusion of LEGO and digital electronics. This is almost where Steampunk and LEGO meet. Hand cranked devices that perform complex mechanical tasks.

As we revel in the satisfaction of making round pegs fit, we might recall that it was on this date in 1271 that Genghis Khan’s grandson and Coleridge’s celebratee Kublai Khan renamed his empire “Yuan,” officially marking the start of the Yuan Dynasty of Mongolia and China.  By 1279, the Yuan army had defeated the last resistance forces of the Song Dynasty, which it succeeded.
