Security

In the Middle Ages, before the advent of street lighting or organized police forces, fortified cities and towns used to discourage vandals by closing their gates and laying chains across their roads, “as if it were in tyme of warr.” Historian A. Roger Ekirch writes that Nuremberg “maintained more than four hundred sets [of chains]. Unwound each evening from large drums, they were strung at waist height, sometimes in two or three bands, from one side of a street to the other … [and] Paris officials in 1405 set all the city’s farriers to forging chains to cordon off not just streets but also the Seine.”

In some cities, residents who’d returned home for the night were required to give their keys to the authorities. A Paris decree of 1380 reads, “At night all houses … are to be locked and the keyes deposited with a magistrate. Nobody may then enter or leave a house unless he can give the magistrate a good reason for doing so.”

Waste Not, Want Not

In 1929, Indiana Bell bought the Central Union Telephone Company of Indianapolis. Central Union’s headquarters building at that time was more than 20 years old and inadequate to the new company’s needs, but rather than demolish it, architect Kurt Vonnegut Sr. (father of the novelist) proposed moving it out of the way.

Over the course of a month, the 10,000-ton building was shifted 52 feet south, rotated 90 degrees, then shifted another 100 feet west. Amazingly, this was all accomplished while the building was open and operating — customer telephone service was never interrupted, and the building’s gas, heat, electricity, and water operated continuously throughout the move.

A new headquarters was built on the old site, and the shifted building stood in its new position until 1963.

Brave New World

In 1921 Charles Steinmetz, “the electrical wizard of Schenectady,” described the conveniences of 2021:

When heating is all done electrically, and I want 70 degrees in my home, I shall set the thermostat at 70 and the temperature will not rise above that point. This temperature will be maintained uniformly regardless of the weather outside.

This will also hold true on the warm day when the temperature outside may be 90 or 100 degrees. The same electrical apparatus will cool the air, and what’s more it will also keep the humidity normal at all times.

“Look back 100 years and it is like jumping into the Dark Ages,” he wrote. “The electrical development is still in its infancy.”

Out of the Way

Thomas Heatherwick designed this “rolling bridge” in 2002 as part of a redevelopment of London’s Paddington Basin. When not in use it curls into an octagon half the width of the waterway, and when extended the eight sections form a 12-meter footbridge.

It won the 2005 British Structural Steel Design Award in 2005.

First Contact

Moving beyond attempts at merely contacting the dead, artist Attila von Szalay claimed to be the first researcher to actually record the discarnate voices of the spirit world. Von Szalay’s quest began in 1936, while he worked in his darkroom. He claimed to hear in this darkened chamber the voice of his deceased brother calling his name. A subsequent interest in Yoga, meditation, and Eastern philosophy made him better able to hear such voices, and in 1941 he attempted for the first time to record the spirits on a 78 rpm record (with disappointing results). It wasn’t until 1956 that von Szalay ‘successfully’ recorded such phenomena, this time using a reel-to-reel tape recorder. Perhaps unaware of their importance in the history of telecommunications, the first recorded spirit voices offered such banal messages as ‘This is G!,’ ‘Hot dog, Art!,’ and ‘Merry Christmas and Happy New Year to you all.’ These pioneering sessions were reported by noted psychic researcher Raymond Baylass in a letter to the Journal of the American Society for Psychical Research in 1959.

Storm Warning

When a truck ignores repeated alerts that it’s too tall to enter the Sydney Harbour Tunnel, an automated system projects a giant stop sign onto a curtain of water at the tunnel entrance. This presents the boldest possible message without causing damage to a heedless truck — and authorized vehicles can still pass safely through the curtain.

The Endless House

In 1924 architect Frederick Kiesler proposed a house fashioned as a continuous shell rather than an assembly of columns and beams:

The house is not a dome, but an enclosure which rises along the floor uninterrupted into walls and ceilings. Thus the safety of the house does not depend on underground footings but on a strict coordination of all enclosures of the house into one structural unit. Even the window areas are not standardized in size or shape, but are, rather, large and varied in their transparency and translucency, and form part of the continuous flow of the shell.

Storage space is provided between double shells in the walls, radiant heating is built into the floor, and there are no separate bathrooms, as bathing is done in the individual living quarters.

“While the concept of the house does not advocate a ‘return to nature’, it certainly does encourage a more natural way of living, and a greater independence from our constantly increasing automative way of life.”

Podcast Episode 335: Transporting Obelisks

https://commons.wikimedia.org/wiki/File:Cleopatra%27s_needle_being_brought_to_England,_1877_RMG_BHC0641.tiff

In the 19th century, France, England, and the United States each set out to bring home an Egyptian obelisk. But each obelisk weighed hundreds of tons, and the techniques of moving them had long been forgotten. In this week’s episode of the Futility Closet podcast we’ll follow the struggles of each nation to transport these massive monoliths using the technology of the 1800s.

We’ll also go on an Australian quest and puzzle over a cooling fire.

Easy Does It

South of Brusio, in the Swiss Canton of Graubünden, the Bernina railway must change elevation without exceeding its specified maximum gradient of 7 percent. So engineers adopted the appealing expedient of a spiral viaduct, an arch bridge of nine spans that carries a train through 360 degrees with a grade gentle enough to ensure safety.

Opened in 1908, it was recognized as a UNESCO World Heritage Site in 2008.

The Blackbird is a full-size playable stone violin crafted by Swedish sculptor Lars Widenfalk. The instrument incorporates diabase from his grandfather’s tombstone, with a backplate of porphyritic diabase, both materials more than a billion years old. The design is based on drawings by Stradivarius, but Widenfalk made some modifications to allow it to be played.

The fingerboard, pegs, tailpiece, and chinrest are of black ebony, and the bridge is of mammoth ivory. “What drove me on was the desire to discover the limits to which this stone can be pushed as an artistic material,” Widenfalk said. “At two kilos it is heavier than wooden violins, but it gives you the feel that you are carrying Mother Earth.”
