An elegy thought over the carrion of a nighthawk

This was really such a startling picture to come across. The F-117 Nighthawk was certainly for me, and I think at least for many boys growing up around the collapse of the Soviet Union, the quintisential icon of the infinite possibility of American military technology. It was The Stealth Fighter, invisible, invincible, built of a super high tech material that would absorb radar and make the whole plane look no bigger than a sparrow upon an enemy’s screen. It was super top secret, and even knowing about it gave one the sense of some how being included in all of that intrigue and magic. But, if WE know about THIS, can you just imagine all the things they are not telling us? They must even more fantastic things, maybe even X-Files and secret UFO technology. They did, after all, develop and test it at Area 51.

But now here it is. Torn apart by an ordinary Caterpillar excavator, reduced to a formless tangle of industrial material, like one saw in the pictures dispatched from New Orleans, or South Ossetia. Giving up the ghost, the spell is broke, the charm is flown. There was so much promise in you, oh Nighthawk. Yours was a special place, a harbinger from the coast, signaling the floods would soon recede and Eden would be reclaimed. But as they have stripped you of your feathers, we too must go naked for a season.

The bottom of the barrel, or a brief anatomy of an oil well

It was not until the fantastic rise in energy prices of the last several years (remember: a decade ago a barrel of crude was less than $15) that companies that do oil exploration and production (E&P) began a serious consideration of extracting the very low grade bitumen (essentially the most expensive part of a barrel of oil to refine, and directly the stuff that holds the stones together in asphalt). When prices looked as if they were heading straight for $100, and even more so when it looked like they were heading straight for $200, companies began investing heavily in the Canadian province of Alberta, which is estimated to hold 1.7 trillion barrels of oil, according to government sources. However, the recent turn around in the direction of oil prices, combined with the banking crisis which is (1) making it difficult to put together financing for exploration projects and (2) creating concerns that the slowing economy will push oil below $70, the price that determines profitability for these projects, has cast the future in doubt. All of that said, the physical process by which oil is extracted from the ground is quite interesting and something that is as mysterious as the magic smoke inside an ipod to most people. So for your edification, take a look at the diagram below:

The above image, taken from an investor presentation given by Petrobank, an E&P company working in Alberta, shows the basic anatomy of a well site.

  • The vertical well sections are drilled about 1.5km on average, although they could get as deep as 3-4km
  • Once the drill reaches the oil sand deposits, the direction will be changed so that the well will continue horizontally. This is done because the seam containing the oil sand is relatively shallow and the more surface the well can make contact with, the more production that will follow.
  • Once the actual hole of the well is drilled, it is shored up with a high pressure casing that maintains the structural stability of the well.
  • Following this, the casing is fractured in many places using explosives. This has the double effect of loosening up the surrounding sand formations, allowing the oil to flow more easily, as well as providing more entry points for oil to flow into the casing.
  • On the surface, the pump jack helps create the pressure required to extract the heavy bitumen from the ground

Biomolecularists develop sewer system for Liliputians, Entomologists promptly crash party

In a new bit of biomimicry (those instances where sciences takes its cue from the structure of systems in the natural world), researchers at Cornell have developed a synthetic system for transpiration.

Scientists theorize that as evaporation occurs on the surface of a tree’s leaves, the resulting drop in water pressure propels water from the earth and through their bodies. The same principle pulls oil through the wick of a candle.

Cornell University researchers modeled the water-transporting tissue, called “xylem,” with fine networks of hydrogel-embedded capillaries. The hydrogel itself had nanometer-scale pores — the same material is used in contact lenses — that allowed water to evaporate, creating the necessary pressure differential.

The artificial tree proved capable of transporting water, raising the possibility of applying transpiration mechanisms to the heating systems of buildings or the cooling systems of computers. [via] [paper published in nature]

The Cornell experiment, however, is not the first time that such reverse engineering of nature has been put to good effect. In 2004, Project TERMES ventured off to Namibia in Southern Africa to map out the structure of the Macrotermes michaelseni termite’s mound. From the press release announcing the expedition, the team stated:

The termite-built towers, standing as high as five metres, epitomise structures that have been optimised for the harsh surroundings they are located in, displaying incredible feats of self-regulation to provide a constant living environment in which the termites can thrive. These wind driven machines, that ventilate the termites’ colony, breathe at about the same rate as a cow and need to be large to continually refresh the air to the subterranean nests.
Understanding how the minuscule termites build these complex mounds may enable engineers and architects to develop new kinds of self-sufficient human habitats, which are able to tap environmental energy like wind and solar power to control their own climate. The biologists also hope that clues to fundamental questions about the evolution of organisms will emerge from this work.

After filling the mound with a type of plaster and then dissolving the exterior walls, the researchers were able to create a 3D model of the internal structure. It is rather amazing that the collective action of these termites has evolved in such a way as to generate this amazingly balanced and harmonious artifact, while our own civilization seems to extrude quite a different, self destructive set of artifacts. Curious.

To much fanfare a few years ago, the Eastgate building was built in Zimbabwe using techniques learned from the study of the termite mounds, yielding 90% higher energy efficiency than buildings of similar size:

This is a terrific example of sustainable architecture that is biomimetic, indigenous, and economically viable on its face. Yet the Eastgate story also demonstrates an important aspect of the sustainability/biomimicry trend – that incrementally greater value may be found by studying solutions from those niches (ecological and economic) where resources are more constrained than the ones you inhabit. Don’t study the oasis – study the desert. More on the Eastgate building is available here and here.

You can see it in the eyes, phantom planet syndrome it is

Brainloop is an interactive performance platform that utilizes a Brain Computer Interface (BCI) system which allows a subject to operate devices merely by imagining specific motor commands. These mentally visualized commands may be seen as the rehearsal of a motor act without the overt motor output; a neural synapse occurs but the actual movement is blocked at the corticospinal level. Motor imagery such as “move left hand”, “move right hand” or “move feet” become non-muscular communication and control signals that convey messages and commands to the external world. In Brainloop the performer is able – without physically moving – to investigate urban areas and rural landscapes as he globe-trots around virtual Google Earth. Through motor imagery, he selects locations, camera angles and positions and records these image sequences in a virtual world. In the second half of the performance, he plays back the sequence and uses Brainloop to compose a custom soundtrack by selecting, manipulating and re-locating audio recordings in real time into the physical space.

If it is true that the devil is in the details…

then god must be in the nanoparticles:

Stained glass windows that are painted with gold purify the air when they are lit up by sunlight, a team of Queensland University of Technology experts have discovered.

Associate Professor Zhu huai yong, from QUT’s School of Physical and Chemical Sciences said that glaziers in medieval forges were the first nanotechnologists who produced colours with gold nanoparticles of different sizes.

Professor Zhu said numerous church windows across Europe were decorated with glass coloured in gold nanoparticles.

“For centuries people appreciated only the beautiful works of art, and long life of the colours, but little did they realise that these works of art are also, in modern language, photocatalytic air purifier with nanostructured gold catalyst,” Professor Zhu said. [link]

An upright and locked position: early aviation

In an old brief case, I came across a map of Western Europe published by National Geographic in 1929. One of the plates published in the margin included a map of the passenger airline service as it existed at the time.

[Link to full map ~1MB]

I imagine that the Budapest –> Vienna flight must have featured a rather marvelous bevy of passengers… Most of the flights in Europe at this point were conducted in re-purposed WWI planes, with rather rough conditions that were, apparently, best endured for less than two hours at a stretch.

Commercial aviation in France was not a serious prospect until after World War I. Because of widespread damage to railroads all over Europe, air travel offered a convenient alternative means of transportation. The cross-channel route from London to Paris also offered a tempting opportunity for enterprising entrepreneurs. Near the end of the war, on February 8, 1919, a group of French businessmen had remodeled the Farman Company’s twin-engine Goliath biplane and began flying routes across the English Channel between Paris and London. By August 1919, Farman was offering daily service on this route for as many as 14 passengers. To attract passengers, the interior of the fuselage was arranged much like a railway coach. The early burgeoning private services, however, proved not to be financially viable because of high operating costs, high fares, and low passenger turnout. French commercial aviation, like aviation in Britain and Germany, would not have survived without strong support from the government.

The French government took an active role in fostering a domestic commercial aviation industry. French officials believed that aviation would be an important part of the country’s economic growth. They also believed that a strong air presence would extend French political and diplomatic influence to the new postwar world. Passenger comfort was not high on many of these services. As one aviation official noted in a report from 1922, “In some airplanes, the passenger cannot stand conditions for more than two hours.”

The Ford Trimotor 5-AT, nicknamed “The Tin Goose,” was used by almost all the U.S. airlines. Introduced in 1928, these planes could carry 14 or 15 passengers in its corrugated fuselage. It was produced through 1932, but these planes stayed in use much longer. One Trimotor 5-AT, built in 1929, was still being used in Las Vegas for sightseeing in 1991.

Lithographic inscriptions, old and new

May we first start with a passage from Wilhelm von Humboldt’s “The limits of state action” (1810):

Now man never regards that which he possesses as so much his own, as that which he does; and the labourer who tends a garden is perhaps in a truer sense its owner, than the listless voluptuary who enjoys its fruits…

In view of this consideration, it seems as if all peasants and craftsmen might be elevated into artists; that is, into men who love their labour for its own sake, improve it by their own plastic genius and inventive skill, and thereby cultivate their intellect, ennoble their character, and exalt and refine their enjoyments.

It does seem to be, in a most tragic way, this very idea of the human as a beautiful and nearly impossible consequence of a mysterious cosmic chemistry that is concealed and denied so very profoundly in modern life. It is therefore always a sincere pleasure to see instances of workers surreptitiously inserting an expression of themselves into work that is otherwise supposed to conform to a contractually predetermined sterility.

I came across two examples presented here: that of concealed sculptural ornamentation on New York City highrises built during the 1920s-1930s and that of chipart, or invisible icons included by semiconductor engineers on the various chips that they worked on. Both of these examples seemed to fit nicely under the heading of lithography, although under rather different usages of the word. (Lithography as “stone writing” and as the chemical process by which semiconductors are fabricated).

Part 1. Skyscrapers

This first set of images comes from an October 1933 issue of Modern Mechanix [PDF] which was sourced from the very marvelous Modern Mechanix blog.

The above picture, described in the magazine as a janitor who is “in his natural state, sound asleep”. Despite this rather snarky reading of the image by the article’s author, does it not rather seem that the bespectacled janitor, with a book on his lap, and a finger perched upon his chin, is privately considering some story or poem he may have just read?

Left: “The modern girl, with a cigarette and a cane is found perched on the fourth floor of a New York building in a niche where no one was told to place her”((((how scandalous))) Right: “The man may be the grasping landlord, for he has a big bag of money which he is putting away in a safe” ((((excellent deduction Watson!)))

Left: “On one of New York City’s most modern skyscrapers, appears a carved figure of a lone fisherman. No one seems to know the meaning of it nor why its there” Right: “Directly opposite the figure of this boy with a pea shooter is a grouchy old man”

Part 2: Chipscrapers

Chip art, or chip graffiti, refers to the practice by semiconductor designers of including personalized tags or iconography on the chips that they design. To get a sense of where this happens, see the zoom in below:

The microprocessor chip (left) as it appears on the screen should appear roughly the same size as it would in real life. If you have ever seen a circuit board, this chip would be one of the squares or rectangles covered in black plastic.

The practice of including art in chip designs experienced its golden age in the 1970s and 1980s. During this time, in contrast to the contemporary practice and ethos of semic design, the entire design cycle was managed by a single team of engineers who became very invested in the integrated design of a chip (now modular design practices split the development across different groups of engineers and library’s of preexisting schematics). This change has led to a deemphasis of a certain engineer or group of engineers being motivated to tag their chips because it feels, in some ways, less so their own. Coupling with this almost Fordist change of events, increased pressure for tight time lines and rapid turn around has further braked, but by no means silenced, the practice of chip art.

”We all did it,” said Dan Zuras, a chip designer at Hewlett-Packard. ”Eighteen or 20 years ago, they were all over the place.”

Designs were usually etched into the upper metallic layers of the chip, creating the impression of an image in relief on the surface. The cartoons grew out of the ritual of having chip designers sign or initial chips they had worked on. For example, Mr. Zuras drew a Roadrunner on a then-fast Hewlett-Packard 1AK9 chip in 1982. ”Back in those days, I knew where every one of the 153,000 transistors were on the chip,” he said. ”I knew it so well that I signed it, like writing your name in wet concrete after you’ve poured a driveway.” [via 1999 NYT article]

For the most part, up until the 1990s, these doodles fell beneath the radar of semiconductor corporate management and therefore did not invite too much scrutiny. However, after a few mishaps occurred–flaking from one caused a short circuit in a design, a very expensive accident–much stricter controls were imposed on designers including more intensive error checking programs. Even so, if a group of engineers can get their design past the checking programs, then for the most part companies will not make too much of a stink. However, there is a bit of cultural variation on this account: no one has found examples of chip art on Japanese chips, but it seems to be reasonably common on European and most American designs.

It is important to take note that most of the knowledge about chip art is fundamentally coincidentally and may in fact largely slip away into oblivion. There are two main sources who have been systematically discovering and publishing examples of chip art. Without their efforts, the stories of these artifacts would be largely forgotten as the engineering cliques that they helped cement die off, leaving only the archeologists to wonder over them in the future.

Skimming like Google Terra-nauts across the surface of integrated circuits are Chipworks, a company that does reverse engineering on integrated circuits for intellectual property disputes and the Molecular Expression Lab, run by Mike Davidson, who spend lots of time aiming high powered microscopes at all sorts of things from metorites to Ben and Jerry’s ice cream.

This sailboat, from a 1970s Texas Instrument chip, is the earliest example of chip artwork found so far.

A chip used in Digital Equipment’s MicroVax 3000 and 6200 minicomputers carries a message in Russia’s Cyrillic alphabet: “VAX–when you care enough to steal the very best.” The message was intended for technicians on the other side of the Cold War who might try to reverse-engineer the VAX designs by looking closely at the originals.

Appearing as an opposed duet of helmeted gladiators, these angry silicon soldiers were discovered on the surface of an image sensor used by the Spirit and Opportunity rovers sent to probe the Red planet.

From Mike Davidson at the Molecular Expression Lab: “We caught this silicon version of Waldo (that is about 30 microns in size) hiding among caches, buses, and registers while searching through many thousands of square microns of complex circuitry with a high-power optical microscope. Waldo is the first Silicon Creature that we discovered, and this led to an exhaustive search for more creatures and construction of the Silicon Zoo gallery.”

Mercenary optics come to a blog post near you

Attributor, a silicon valley start up a few years and 32-million dollars in the making, provides an impressive panorama of cyberspace. Employing similar techniques to Google’s search indexing process, Attributor dispatches spiders across the web that search all new content published in the blogosphere and social networks. Its objective in this exploration is to monitor the usage and propagation of copyrighted material and to use this information either to intervene or to study the pathology of viral content.

As might be expected, this business model has quite a bit of traction in the market today. Indeed, Attributor has scored some large contracts for their wide-net surveillance system including Reuters, The Associated Press and the Conde Nast Group.

But what does this type of system foretell about the relationship between the producers of media and those who comment upon and critique it? The arguments posed on the web run rather simply: A. Surveillance technologies like Attributor impede the flow of information by creating circumstances of a de facto, abusive restriction of fair use OR B. Content management technologies like Attributor allow content creators to benefit from their work by having total knowledge of its online uses and either (1) being able to collect credit\revenue from it or (2) to better appreciate the reception of their own work by the public.

Both sides certainly have some points in their favor, but regardless of the synthetic arguments that can be eloquently presented on the issue, there are some underlying creepy forces at play. Marketing materials for Attributor proclaim a near real time awareness of content across 19 Billion pages throughout the web. What are the implications of such a vast, mercenary optics? What do the designators private and public mean when one is applying them to discourse on the web? Certainly everything published and accessible by means of an open hyper text transfer protocol is offered up to the public, but what about an industrial-automated surveillance robot? Is such an entity entitled to interface with the public? Does it have rights? An old world analogue of what Attributor does would involve, let us say, an author writing about new airship technology who quotes a Boeing press release. Consequent to this, Boeing dispatches a van to sit in front of said author’s house and photograph it for a few minutes before driving off.

One must ask, is this a reasonable research initiative on the part of Boeing so that they may understand the architectural and design environments of those people that write about them, or a a type of coercive invasion? How do things change when the case becomes one computer connecting to another instead of men in vans with cameras? Is it more seemly because it is simply a relationship of two machines? Or is something of the first moment preserved? Since it is an actor upon the stage, who is this virtually unknown visitor, what is Attributor?

When does one capitalize “Never”?

In a bizarre twist brought about by the 11 September 2001 terrorist attacks, Pripyat (((1985: population 50,000))) is getting a new lease on life. People will never move back into the deteriorating Soviet-era apartments. Instead, scientists are planning to use the radioactive ghost town as a unique laboratory for modeling the dispersal of radionuclides by the detonation of a dirty bomb. [Article from Science: PDF]

Will people never live there again? 24,000 years from now – if the zone’s keepers are right, and if the reactor’s extra-human carcinogenic hell raising center is safely interred, not having leaked into the River Dneiper, then half of the plutonium 239 buried at Chernobyl will still be there. If this does not inspire the journalist to capitalize the designation never, can it ever in good grammar suffer such aggrandizement? To capitalize a letter out of turn, what is this act of writing? The shortest answer would be for emphasis. But to do so to a common word is to possibly conflate it with a Proper noun (if this is the case, then what the hell is an iPhone?). Is such a conflation desirable under any circumstance? What would the proper noun Never refer to? Is it a collective will of humanity? A hope for a collective will expressed by an author? But who except the most depraved amongst the humans would contradict a foreclosure of such disaster? Is this not a natural position of the human? An indelible position that suffers no history and knows no abberation?

Well let US meditate on the matter, recalling the facts at hand:

Nobody has to twist the facts of Chernobyl. One by one the Ukrainian, Belarus and Russian health chiefs recite their litanies of loss. The figures are on an unimaginable scale. Some 23 per cent of the land of Belarus is contaminated, and on that land live 20 per cent of the population. More than 250,000 hectares of farmland have been closed down; 130,000 have had to be resettled.

Childhood thyroid cancer is 90 times the levels before 1986. There will be 140 cases of thyroid cancer every year. Breast cancer is on the increase; so are disorders of the blood circulation. Almost 2 million people in 3,331 towns and villages need “special attention”. The republic needs “clean” food, diagnostic equipment, radiation instruments and rehabilitation centres, and will need to spend $400-500m between now and 1995.

The Ukrainians tell a similar story: 190 people have acute radiation sickness; 20,000 have lost the capacity to work; there are 130,000 evacuees; there are 1.5 million children whose thyroid glands received radiation doses. There are people with respiratory disease, heart troubles and nervous system disorders. There are increased digestive problems, tonsilitis, anaemia and stress. There is an increase in suicide. There are children with “Chernobyl syndrome”.

The Russians, too, tell of 2.6 million people in 7,608 contaminated towns; of a 25 per cent increase in tumours; of a 50 per cent increase in cardiovascular disorders; of locomotor apparatus diseases.

Scientists refer to the zone as a “unique laboratory” and scientists from 28 nations have worked there. But it is difficult to feel objective about it. Here is a landscape so contaminated by its only heavy industry that it has been turned inside out: used as its own graveyard, buried within itself. Most of the iodine 131 disappeared long ago. In another 20 years, the strontium 90 will have fallen to half its original burden. In another 20 years, half of the caesium 137 will have disintegrated.

But 24,000 years from now – if the zone’s keepers are right, and the stuff is safely interred, and hasn’t leaked into the River Dneiper – half of the plutonium 239 buried in it will still be there. [link]

An abandoned village house near Chernobyl

There are even tantalising footprints of a bear, an animal that has not trodden this part of Ukraine for centuries.

“Animals don’t seem to sense radiation and will occupy an area regardless of the radiation condition,” says radioecologist Sergey Gaschak.

“A lot of birds are nesting inside the sarcophagus,” he adds, referring to the steel and concrete shield erected over the reactor that exploded in 1986. [link]

The Red Forest is located in the “zone of alienation”: this area received the highest doses of radiation from the Chernobyl accident and the resulting clouds of smoke and dust. The name ‘Red Forest’ comes from the ginger-brown colour of the pine trees after they died following the absorption of high levels of radiation from the Chernobyl accident on April 26, 1986. In the post-disaster cleanup operations, the Red Forest was bulldozed and buried into ‘waste graveyards’. The explosion and fire at the Chernobyl No. 4 reactor contaminated the soil, water and atmosphere with the radiation equivalent to 20 of the atomic bombings of Hiroshima and Nagasaki.

Liquid crystal dreams of an asphalt frontier

The “Digifiz” add-on, pictured above, was first introduced in the Volkswagen Golf in 1985 and was continually offered as a feature until 1992. Such product design emerged from the days when the future was being reborn, when electronic synthesizers pumped out 8-bit staccato and glistening liquid crystal offered the masculine promise of evading any nuclear nastiness that might arise (see Corvette ad below) all while simultaneously pushing forward a cutting edge, revealing the futures to come. It seems that immediately after LCD technology became commercially scalable a huge proliferation of it spread across all forms of consumer products, bringing with it an amulet of mystique and promise to the consumer device adorning it. A mystique and promise, mind you, unavailable to those lousy Soviets.

For your consideration, Motive Magazine has pulled together videos of 12 examples of 1980′s digital car instrumentation panels. Take note of the 1987 Buick Rivera, which was the first production car to include a touchscreen monitor.
