Pictures of Motion

joinville soldier walking

In 1883, in his studies of the human gait, French physiologist Étienne-Jules Marey asked a soldier to walk past a camera with an open shutter. Before the lens Marey had placed a rotating disk in which he’d cut slots at regular intervals. As the soldier walked, the slots permitted successive images to register on the same photographic plate, producing a “chronophotograph” — a portrait of human movement in time and space.

This opened a new window into the representation of motion — among other things, it helped to inspire Marcel Duchamp’s 1912 Nude Descending a Staircase:

Duchamp said, “The idea of describing the movement of a nude coming downstairs while still retaining static visual means to do this, particularly interested me. … My aim was a static representation of movement, a static composition of indications of various positions taken by a form in movement.”

Engineer Frank Gilbreth, who made a science of optimizing human movement, at one point used a similar technique to study the swing of Connecticut golf champion Roger Hovey. He was surprised to find that the path of Hovey’s upswing varied from that of the downswing by more than 12 inches, and his head moved more than a foot. Intrigued, he studied Gilbert Nicholls, and later Francis Ouimet and Jim Barnes. All varied their swings, and all moved their heads.

When Gilbreth showed these results to a friend in London, “his only comment was to the effect that he had previously suspected that we didn’t know much about golf in America. Which only goes to show.”

Peace and Quiet

Ohio inventor Philip Clover came up with a dramatic way to discourage body snatchers in 1878: a “coffin torpedo.” Basically a live cartridge is attached to the body by hidden wires so that “any attempt to remove the body after burial will cause the … injury or death of the desecrator of the grave”:

The trigger-wires are secured to the arms, legs, or other portion of the body of the corpse in such manner as to induce to the tripping of the trigger should any attempt be made to withdraw the body from the casket. The torpedo is loaded … just prior to the final closing of the casket.

“The torpedo may be placed in variable positions within the casket, and properly concealed by the trimmings of the casket or the apparel of the corpse.” Clover points out that there’s no need to protect the weapon from the elements — by the time it ceases to work, “the body would be of no use to robbers.”

Paint by Number

When Mariner 4 flew past Mars in summer 1965, NASA scientists were eager to get their first close look at another planet. So rather than wait for their computers to render the probe’s data into a proper photograph, the employees in the agency’s telecommunications group mounted printed strips of data in a display panel and colored them by hand to create a rough visualization.

The hand-colored vista became the first image of Mars based on data collected by an interplanetary probe. They framed the finished image and presented it to agency director William H. Pickering.

From Beyond

From the St. Louis Post-Dispatch, via the Ohio Law Reporter, Aug. 17, 1908: During a dispute over a will in Vienna, a phonograph record was introduced into evidence so that the dead woman herself could explain her intentions, which she’d recorded during her lifetime:

Prof. Sulzer stated that he had a phonographic record that would settle beyond question the point in dispute and asked the court’s permission to introduce it as evidence. The permission was granted and Mme. Blaci, the decedent, told in her own voice of her affection for her brother and his family and announced her intention of providing before her death so that her nephew, Heinrich, would be well cared for after she had passed away.

Heinrich testified that the record was made on the twenty-first anniversary of his birth. Mme. Blaci, he told the judge, had said at the time that she wanted the words she had spoken to her brother, Heinrich’s father, put on record as a souvenir of her affection that could be handed down to her nephew.

“After hearing the record, the court immediately awarded Heinrich $120,000 as his share of the estate, which was the full amount claimed by him.”

Parting Words

Inventor Robert Barrows thought up a high-tech memorial in 2005: a hollowed-out headstone equipped with a weatherproofed computer monitor.

“I envision being able to walk through a cemetery using a remote control, clicking on graves and what all the people buried there have to say,” he told the Wall Street Journal. “They can say all the things they didn’t have the opportunity or guts to say when they were alive.”

He estimated that a “video-enhanced grave marker” might add $4,000 to the cost of a high-end $4,000 tombstone. If they really take off we’ll need wireless headsets to keep down the racket at the cemetery:

Tempest-Tost

In 2011 Royal Caribbean introduced a self-leveling pool table on its cruise ship Radiance of the Seas.

This video was shot during a storm in the Pacific — gyroscopes inside the table keep the playing surface level so a game can continue even as the ship rolls.

Tech Talk

In 1944 British graduate student John Hellins Quick published a description of the “turbo-encabulator,” a marvelously sophisticated device whose workings are understandable only by engineers:

The original machine had a base-plate of prefabulated aluminite, surmounted by a malleable logarithmic casing in such a way that the two main spurving bearings were in a direct line with the pentametric fan. The latter consisted simply of six hydrocoptic marzelvanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-delta type placed in panendermic semi-bovoid slots in the stator, every seventh conductor being connected by a nonreversible tremie pipe to the differential girdle spring on the ‘up’ end of the grammeters.

General Electric, Chrysler, and Rockwell Automation have all sung the device’s praises, even if no one can quite explain what it does. Actor Bud Haggart shot the video above in 1977 after completing an industrial training film for General Motors.

The rest of us will just have to take its wonders on faith. When Time magazine published the description in 1946, one reader wrote, “My husband says it sounds like a new motor; I say it sounds like a dictionary that has been struck by lightning.”

Overheard

On May 10, 1857, the Indian troops of the East India Company’s army started an uprising against the British soldiers in the garrison town of Meerut.

Lord Canning, the Governor-General, first heard of the Mutiny in a curious fashion. The Lieutenant-Governor of Agra passed on to him a copy of a private telegram which had been sent by the British postmaster at Meerut before the line was cut. The postmaster’s aunt was in Agra and had planned to visit him. He wired that the cavalry had risen, houses were on fire and Europeans were being killed. ‘If aunt intend starting tomorrow evening please detain her.’ It was several days before the Governor-General of India could learn more than this of what had taken place in Meerut. Only gradually did the news of what had happened and what was happening in northern India seep out to the rest of the world.

That’s from Byron Farwell, Queen Victoria’s Little Wars, 1973. Related: On Sept. 1, 1939, English journalist Clare Hollingworth called the British embassy in Warsaw to report that Germany had invaded Poland. The secretary told her this was impossible, as Britain and Germany were still negotiating. “So I hung the telephone receiver out of the window,” she later recalled, “so he could listen to the Germans invading.” Hers was the first report that the British Foreign Office received of the invasion — later described as “the scoop of the century.”

The Disintegration Loops

In 2001 avant-garde composer William Basinski was trying to transfer some old tape loops to digital format, but he found that the original recordings had deteriorated so badly that the ferrite simply fell off the plastic backing as it passed the tape head. Intrigued, Basinski let the loops continue to cycle: the sounds grew more and more indistinct with each pass as the tape literally fell apart.

As it happened, the 9/11 attacks occurred on the morning he finished the project, and the devastation he videotaped from his rooftop seemed to sync with the new recordings. “I felt, with my experience being in New York at that time, and what I went through and what I saw my friends go through, I wanted to create an elegy,” he told NPR. “Yes, there’s that tie to 9/11. But the thing that moved me so profoundly in my studio right after this music happened was the redemptive quality. The music isn’t just decaying — it does, it dies — but the entire life and death of each of these unique melodies was recorded to another medium for eternity.”

Related: In 1969 composer Alvin Lucier recorded a paragraph of speech, then repeatedly played it back and re-recorded it, so that his voice merged gradually into a portrait of the room’s resonant frequencies.

Here’s a modern homage to Lucier using YouTube, showing the effects of ripping and uploading the same file 1,000 times:

Scoop

In February 1966, the Soviet Union’s Luna 9 landed safely on the moon and became the first spacecraft to transmit photographs of the moon seen from surface level.

The Soviets didn’t release the photos immediately, but scientists at England’s Jodrell Bank Observatory, who were observing the mission, realized that the signal format was the same as the Radiofax system that newspapers used to transmit pictures. So they just borrowed a receiver from the Daily Express, decoded the images, and published them.

The BBC observes, “It is thought that Russian scientists had deliberately fitted the probe with the standard television equipment, either to ensure that they would get the higher-quality pictures from Jodrell Bank without having the political embarrassment of asking for them, or to prevent the Soviet authorities from making political capital out of the achievement.”
