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

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.

Rock Music

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.”

Red Flag Laws

In 1865, shortly after the first steam-powered horseless carriage appeared on English highways, Parliament ordered that a man must precede it on foot, carrying a red flag by day or a lantern by night, to warn others of the impending noise:

Firstly, at least three persons shall be employed to drive or conduct such locomotive, and if more than two waggons or carriages be attached thereto, an additional person shall be employed, who shall take charge of such waggons or carriages;
Secondly, one of such persons, while any locomotive is in motion, shall precede such locomotive on foot by not less than sixty yards, and shall carry a red flag constantly displayed, and shall warn the riders and drivers of horses of the approach of such locomotives, and shall signal the driver thereof when it shall be necessary to stop, and shall assist horses, and carriages drawn by horses, passing the same.

Vermont passed a similar law in 1894, requiring the owner of a steam-propelled vehicle to have a “person of mature age … at least one-eighth of a mile in advance of” the vehicle, to warn those with livestock of its approach. At night this person was required to carry a red light.

Both measures were repealed in 1896 — by which time the internal combustion engine was already being developed.

Getting There

Designed by architects in Amsterdam and Beijing, the Lucky Knot Bridge in Changsha, China, combines three bridges in one. Inspired by both the Möbius strip and the Chinese knotting art, the 185-meter pedestrian bridge spans Dragon King Harbor River, connecting multiple levels at varying heights (the river banks, the road, and a park at a higher level) while permitting pedestrians to pass from one route to another using “moon gates.”

“Bridges … have a highly metaphorical quality,” Michel Schreinemachers, a partner at Next Architects, told Wired. “They connect not only in a physical sense, but also people, places, needs, and experiences.”
