Archiving “Geomagnetic Spikes” in Everyday Objects

[Image: One of the pots; photo by Oded Lipschits, courtesy NPR].

Ancient clay pottery in the Middle East has inadvertently recorded the Earth’s magnetic field, including evidence of an “astonishing geomagnetic spike.”

“All those years ago,” NPR reported earlier this week, “as potters continued to throw clay, the molten iron that was rotating deep below them tugged at tiny bits of magnetic minerals embedded in the potters’ clay. As the jars were heated in the kiln and then subsequently cooled, those minerals swiveled and froze into place like tiny compasses, responding to the direction and strength of the Earth’s magnetic field at that very moment.”

Archaeologist Erez Ben-Yosef, one of the researchers on the project, has compared the process to a terrestrial “tape recorder,” and a particularly sensitive one at that: the resulting jars “provide an unprecedented look at the planet’s magnetic field over those six centuries, one that’s much harder to get from rocks.”

These accidental indices also indicate that the Earth’s magnetic field at the time was much stronger than expected; ominously, this “astonishing geomagnetic spike,” as mentioned above, could happen again. Indeed, the jars have “given scientists a glimpse of how intense the magnetic field can get—and the news isn’t good for a world that depends on electrical grids and high-tech devices,” Annalee Newitz writes for Ars Technica.

“The researchers note that this geomagnetic spike is similar to another that occurred in the 10th century BCE,” Newitz adds. “Data from the 10th century spike and this 8th century one indicate that such events were probably localized, not global. That said, they write that ‘the exact geographic expanse of this phenomenon has yet to be investigated, and the fact that these are very short-lived features that can be easily missed suggests that there is much more to discover.’”

This vision—of highly localized, mysterious geomagnetic storms frying electronics from below—is not only a great plot device for some burgeoning scifi novelist, it could also almost undoubtedly be weaponized: subterranean geomagnetic warfare against an entire region of the planet, short-circuiting every electrical device in sight.

Of course, it’s also worth noting that this would still be happening: that is, today’s ceramics should still be “recording” the Earth’s magnetic field, even without any corresponding spike in that field’s strength. An invisible terrestrial forcefield is thus still inscribing itself inside objects in your kitchen cabinet or standing on your breakfast table. Everyday knick-knacks in retail stores around the world are still archives of planetary magnetism.

This also makes me wonder what other types of artifacts—clay figurines from nomadic Arctic tribes, mud bricks from central Africa—might also house geomagnetic records yet to be analyzed by modern technology. So what else might be discovered someday?

I’m reminded of the possibility that space weather—or “fossils of spacetime”—might be frozen into the built environment in the form of GPS glitches: hidden inside minute structural errors in large building projects, such as freeways, dams, and bridges, there might be evidence that our solar system is passing through “cosmic kinks” of dark matter.

In any case, read the original paper in PNAS; see also The New Yorker.

The Season of Burning Trucks

Stories of GPS directions run amok are a dime a dozen these days: gullible travelers led astray by their iPhones or dashboard navigation systems, driving for hours into the desert night, straight into mountain lakes, up unpaved rural roads that are clearly no more than footpaths, or even halfway across Iceland before they realize something’s wrong.

But there is still something remarkable and almost Raymond Carver-esque about this story of a small town in Arkansas being visited—over and over again—by runaway trucks, their drivers misled by GPS, their vehicles mechanically unprepared for the town’s sharp curves and steep terrain. “Several of them go through here with their brakes smoking or on fire,” a local resident tells ArkansasOnline.

This vision of a town—population a mere 100—now seeing the blazing and violent side-effects of digital navigation technology is both hilarious and beautifully symbolic of the larger phenomenon, of people becoming over-reliant upon algorithmic systems and finding their journeys no longer proceeding as planned.

Like freak weather caused by atmospheric events halfway across the country—bringing unexpected local snow or unseasonably heavy rain hundreds of miles away—intangible changes in route-mapping software send burning trucks roaring through a remote mountain town.

It is both a macabre spectacle and a symptom of bigger technological shifts—before, of course, those same algorithms receive slights tweaks and all those trucks, as mysteriously as they first arrived one night, halo’d in oily flames, now cease to appear.

Imagine being five or six years old in a town like that, not knowing what GPS is, looking out from the darkness of your bedroom over several weeks of late nights, and living through this season of burning trucks, those infernal visitors from further up the mountainside, tumbling down past houses, trailed by smoke, their fiery wheels reflecting bright red in the windows of parked cars. It’s like the visions of Ezekiel, updated for an age of car accidents and Google Maps.

Where are they coming from? And why? Then it all stops and the mystery deepens.

Global Positioning Shift

Australia, it turns out, is not quite where maps think it is. Thanks to plate tectonics, the island nation is moving north by 1.5 centimeters a year, which means that the entire country is now nearly five feet further north than existing cartography suggests it should be.

As a result, Australia’s lat/long coordinates are going “to shift,” the BBC reports.

Interestingly, “the body responsible for the change said it would help the development of self-driving cars, which need accurate location data to navigate.” In other words, the navigational capabilities of autonomous vehicles and other self-driving robots are, at least indirectly, affected by plate tectonics—by the ground literally moving beneath their wheels.

“If the lines [of latitude and longitude] are fixed, you can put a mark in the ground, measure its co-ordinate, and it will be the same co-ordinate in 20 years,” explained Dan Jaksa of Geoscience Australia. “It’s the classical way of doing it.”
Because of the movement of the Earth’s tectonic plates, these local co-ordinates drift apart from the Earth’s global co-ordinates over time.
“If you want to start using driverless cars, accurate map information is fundamental,” said Mr Jaksa.
“We have tractors in Australia starting to go around farms without a driver, and if the information about the farm doesn’t line up with the co-ordinates coming out of the navigation system there will be problems.”

Put another way, gaps have been opening up between the world of robotic navigation and the actual, physical barriers those machines seek to navigate.

You could perhaps argue that there is our Australia—that is, a human Australia of streets, walls, and buildings—and then there is the machines’ Australia, a parallel yet intersecting world of skewed reference points and offset walls, a kind of ghost nation, inhabited only by robots, departing further and further from the limits of human geographic experience every day.

Of course, this would not be the first time that the accuracy of geographic information has a measurable effect on precision agriculture. However, it is also not the first time that geographers have realized that they don’t know precisely where a country really is.

In his recent book about GPS, Pinpoint, author Greg Milner writes about “the geopolitical importance of geodesy,” or the study of the Earth’s exact geometric shape (it is an “oblate spheroid”).

“The geopolitical significance of geodesy increased with the onset of the Cold War,” Milner writes. “In a very real sense, the West did not know the exact location of the USSR”—and, thus, did not know exactly how or where to target its missiles. “‘Missiles were the big drivers in getting the datums tied down,’ Gaylord Green remembers. ‘If I wanted to hit a target in Russia, I couldn’t hit squat if I didn’t have their datum tied down to mine.’”

Briefly, it’s worth pointing out a fascinating side-note from Milner’s book: “The trajectory a missile follows is influenced by the gravity field where it is launched, and its aim can be disrupted by the gravity at the target, so countries often kept their gravity data classified.” I love the John le Carré-like implications of classified gravity data, including what it might take to smuggle such info out of an enemy nation.

But let’s go back to the missile thing: in addition to the question of how farm equipment and other self-driving vehicles can successfully navigate the landscape when they don’t, in fact, have the correct terrestrial coordinates, Australia’s strange misplacement on global maps implies that every potential military target in the country would also have been roughly five feet away from where existing charts say they are.

An old, uncorrected missile system in a decaying military base somewhere mistakenly fires sixty years from now, rockets off toward Australia… and plummets into the sea, missing its coastal target by several feet. Plate tectonics as a slow national defense mechanism.

Books Received

Somewhere, despite the weather here, it’s spring. If you’re like me, that means you’re looking for something new to read. Here is a selection of books that have crossed my desk over the past few months—though, as always, I have not read every book listed here. I have, however, included only books that have caught my eye or seem particularly well-fit for BLDGBLOG readers due to their focus on questions of landscape, design, architecture, urbanism, and more.

For previous book round-ups, meanwhile, don’t miss the back-links at the bottom of this post.


1) The Strait Gate: Thresholds and Power in Western History by Daniel Jütte (Yale University Press)

Daniel Jütte’s The Strait Gate seems largely to have slipped under the radar, but it’s my pick for the most interesting architectural book of the last year (it came out in 2015). It has a deceptively simple premise. In it, Jütte tells the story of the door in European history: the door’s ritual symbolism, its legal power, its artistic possibilities, even its betrayal through basic crimes such as trespassing and burglary. He calls it “a study of doors, gates, and keys and a history of the hopes and anxieties that Western culture has attached to them”; it is a way of “looking at history through doors.”

Jütte describes locks (and their absence), city walls (and their destruction), marriage (and the literal threshold a newly joined couple must cross), medicinal rituals (connected “with the idea of passing through a doorway”), even the doorway to Hell (and its miraculous sundering). You know you’re reading a good book, I’d suggest, when something pops up on nearly every page that you need to mark with a note for coming back to later or that gives you some unexpected new historical or conceptual detail you want to write about more yourself. An entire seminar could be based on this one book alone.

2) Witches of America by Alex Mar (Farrar, Straus and Giroux)

Witches of America is simultaneously an introduction to alternative religious practices in the United States—specifically, contemporary paganism, broadly understood—and a first-person immersion in those movements and their cultures. As such, the book is a personal narrative of attraction to—but also ongoing frustration with—the world found outside mainstream beliefs or creeds.

As such, it ostensibly falls beyond the pale of BLDGBLOG, yet the book is worth including here for what it reveals about the spatial settings of these new and, for me, surprisingly vibrant communities. There is the abandoned churchyard in New Orleans, for example, now repurposed—and redecorated—by a group of 21st-century acolytes of Aleister Crowley; there is the remote stone circle built in Northern California by what I would describe as a post-hippie couple with access to land-moving equipment; there is the otherwise indistinguishable collegiate house in central Massachusetts where future “priests” train in the shadow of New England’s peculiar history with witch trials; there is the corporate convention center in downtown San Jose; the overgrown tombs of the Mississippi Delta, where we meet a rather extraordinary—and macabre—burglar; there is even what sounds like an Airbnb rental gone unusually haywire in the hills of New Hampshire.

While descriptions of these settings are certainly not the subject of Alex Mar’s book, it is nonetheless fascinating to see the world of the esoteric, the otherworldly, or, yes, the occult presented in the context of our own everyday surroundings, with all of their often-mundane dimensions and atmosphere. This alone should make this an interesting read, even for those who might not share the author’s curiosity about the “witches of America.”

3) The Work of the Dead: A Cultural History of Mortal Remains by Thomas W. Laqueur (Princeton University Press)

The Work of the Dead looks at the role not just of death but specifically of dead bodies in shaping our cities, our landscapes, our battlefields, and our imaginations. The question of what to do with the human corpse—how to venerate it, but also how to do dispose of it and how to protect ourselves from its perceived pestilence—has led, and continues to lead, to any number of spatial solutions.

Laqueur writes that “there seems to be a universally shared feeling not only that there is something deeply wrong about not caring for the dead body in some fashion, but also that the uncared-for body, no matter the cultural norms, is unbearable. The corpse demands the attention of the living.”

Graveyards, catacombs, monuments, charnel grounds: these are landscapes designed in response to human mortality, reflective of a culture’s attitude to personal disappearance and emotional loss. While author Thomas Laqueur’s approach is often dry (and long-winded), the book’s thorough framing of its subject lends it an appropriate weight for something as universal as the end of life.

If this topic interests you, meanwhile, I also recommend Necropolis: London and Its Dead by Catharine Arnold (Simon & Schuster), as well as Making an Exit: From the Magnificent to the Macabre—How We Dignify the Dead by Sarah Murray (Picador).

4) The Invention of Nature: Alexander von Humboldt’s New World by Andrea Wulf (Alfred A. Knopf)

Andrea Wulf’s biography of Alexander von Humboldt has justifiably won the author a series of literary awards. Its subject matter is by no means light, yet the book has the feel of an adventure tale, pulling double duty as the life-story of a European scientist and explorer but also as a history of scientific ideas, ranging from the origins of color and the nature of speciation to some of the earliest indications of global atmospheric shifts—that is, of the possibility of climate change.

Natural selection, cosmology, volcanoes—even huge South American lakes full of electric eels—the book is a great reminder of the importance of curiosity and travel, not to mention the value of an inhuman world against which we should regularly measure ourselves (and come out lacking). “In a world where we tend to draw a sharp line between the sciences and the arts, between the subjective and the objective,” Wulf writes, “Humboldt’s insight that we can only truly understand nature by using our imagination makes him a visionary.”


5) Sounding the Limits of Life: Essays in the Anthropology of Biology and Beyond by Stefan Helmreich (Princeton University Press)

You might recall seeing Stefan Helmreich’s work described here before—specifically his earlier book, Alien Ocean: Anthropological Voyages in Microbial Seas—but Sounding the Limits of Life is arguably even more relevant to many of the ongoing themes explored here on the blog.

In his new book, Helmreich outlines a kind of acoustic ecology of the oceans, placing deep-sea creatures and shallow reefs alike in a world of immersive sound and ambient noise, now all too often interrupted by the deafening pings of naval sonar. He also uses the seemingly alien environment of the seas, however, to expand the conversation to include speculation about what life might be like elsewhere, using maritime biology as a launching point for discussing SETI, artificial digital lifeforms, Martian fossils (from Martian seas), and much more.

It’s a book about how our “definition of ‘life’ is becoming unfastened from its familiar grounding in earthly organisms,” Helmreich writes, as well as an attempt to explore “what life is, has been, and may yet become—whether that life is simulated, microbial, extraterrestrial, cetacean, anthozoan, planetary, submarine, oceanic, auditory, or otherwise.”

6) Pinpoint: How GPS Is Changing Technology, Culture, and Our Minds by Greg Milner (W.W. Norton)

I had been looking forward to this book, exploring the relationship between mapping and the world, ever since reading an op-ed by the author, Greg Milner, in The New York Times about “death by GPS.” Milner’s book is specifically about the Global Positioning System and its power over our lives: how GPS shapes our sense of direction and geography, what it has done for navigation on a planetary scale, and even how it has transformed the way we grow our global food supply.

7) The Stack: On Software and Sovereignty by Benjamin Bratton (MIT Press)

Design theorist Benjamin Bratton’s magnum opus is a fever-dream of computational geopolitics, “accidental megastructures,” cloud warfare, predictive mass surveillance, speculative anthropology, digital futurism, infrastructural conspiracy theory—a complete list would be as long as Bratton’s already substantial book, and would also overlap quite well with the utopian/dystopian science fiction it often seems inspired by.

In Bratton’s hands, these abstract topics become, at times, almost incantatory—as if William S. Burroughs had taken a day job with the RAND Corporation. As information technology continues to exhibit geopolitical effects, Bratton writes, “borderlines are rewritten, dashed, curved, erased, automated; algorithms count as continental divides; (…) interfaces upon interfaces accumulate into networks, which accumulate into territories, which accumulate into geoscapes (…); the flat, looping planes of jurisdiction multiply and overlap into towered, interwoven stacks…” He writes of “supercomputational utopias” and the “ambient geopolitics of consumable electrons.”

It’s a mind-bending and utterly unique take on technology’s intersection with—and forced mutation of—governance.

8) You Belong To The Universe: Buckminster Fuller and the Future by Jonathon Keats (Oxford University Press)

Jonathon Keats’s new book simultaneously attempts to debunk and to clarify some of the cultural myths surrounding Buckminster Fuller, a man who described himself, Keats reminds us, as a “comprehensive anticipatory design scientist.” For fans of Fuller’s work, you’ll find the usual suspects here—his jewel-like geodesic domes, his prescient-if-ungainly Dymaxion homes—but also a chapter about Fuller’s work with and influence on the U.S. military in an age of nuclear war games and “domino theories” overshadowing Vietnam.


9) Rome Measured and Imagined: Early Modern Maps of the Eternal City by Jessica Maier (University of Chicago Press)

Art historian Jessica Maier’s book suggests that changes in the way the city of Rome was mapped over the centuries simultaneously reveal larger shifts in European cultural understandings of space and geography. Her argument hinges on a sequence of surveys and maps chosen not just for their visual or cartographic power—which is considerable, as the book has many gorgeous reproductions of old engraved city maps, views, and diagrams—but for their influence on later geographic projects to come.

Broadly speaking, the documents Maier discusses are meant to be seen as passing from being artistic, narrative, or abstractly emblematic of the idea of greater “Rome” to a more rigorous, modern approach based in measurement, not mythology.

This widely accepted historical narrative begins to crumble, however, as Maier puts pressure on it, especially through the example of Giovanni Battista Piranesi’s etching of the Campus Martius. This is an image of Rome that “was neither documentary nor reconstructive,” Maier suggests, and that thus had more in common with those earlier, more folkloristic emblems of the city. In today’s vocabulary, we might even describe Piranesi’s Campus Martius as an example of “design fiction.”

10) Till We Have Built Jerusalem: Architects of the New City by Adina Hoffman (Farrar, Straus and Giroux)

This is a remarkable and often beautifully written history of modern Jerusalem, as told from the point of view of its architecture. Jerusalem is a city, author Adina Hoffman writes, that “has a funny way of burying much of what it builds.” It is a place of “burials, erasures, and attempts to mark political turf by means of culturally symbolic architecture and hastily rewritten maps.” The book, she adds, “is an excavation in search of the traces of three Jerusalems and the singular builders who envisioned them.”

Indeed, the book is structured around the lives of three architects. The story of German Jewish designer Erich Mendelsohn—probably most well-known today for his futurist “Einstein Tower” in Potsdam—looms large, as do the lives of Austen St. Barbe Harrison, “Palestine’s chief government architect,” and the “possibly Greek, possibly Arab” Spyro Houris.

Hoffman’s work is a mix of the archaeological, the biographical, and even the geopolitical, as individual building sites—even specific businesses and kilns—become microcosms of territorial significance, embedded in and misused by nationalistic narratives that continue to reach far beyond the boundaries of the city.

11) City of Demons: Violence, Ritual, and Christian Power in Late Antiquity by Dayna S. Kalleres (University of California Press)

City of Demons looks at three cities—Antioch, Jerusalem, and Milan—in the context of early Christianity, when the streets and back alleys of each metropolis were still lined with temples dedicated to older gods and when alleged opportunities for spiritual corruption seemed to lie around every corner. Historian Dayna Kalleres writes that the cities of late antiquity were all but contaminated with demons: imagined malignant forces that had to be repelled by Christian ritual and belief. Cities, in other words, had to be literally exorcized by a practice of “urban demonology,” driven out of the metropolis by such things as church-building schemes and public processions.

While the book is, of course, an academic history, it is also evocative of something much more literary and thrilling, which is a nearly-forgotten phase of Western urban history when forces of black magic lurked in nearly every doorway and civilians faced security threats not from terrorists but from “the marginal, ambiguous, and protean,” from these hidden demonological influences that the righteous were compelled to expunge.

12) City of Thorns: Nine Lives in the World’s Largest Refugee Camp by Ben Rawlence (Picador)

City of Thorns looks at the Dadaab refugee camp in northern Kenya through various lenses: economic, political, and humanitarian, to be sure, but also ethical and anthropological, even to a certain extent architectural.

While author Ben Rawlence’s goal is not, thankfully, to discuss the camp in terms of its design, he does nevertheless offer a crisp descriptive introduction to life in a sprawling settlement such as this, from its cinemas and police patrols to its health facilities and homes. “Our myths and religions are steeped in the lore of exile,” he writes, “and yet we fail to treat the living examples of that condition as fully human.” The camp, we might say in this context, is the urbanism of exile.


13) Ghettoside: A True Story of Murder in America by Jill Leovy (Spiegel & Grau)

I went through a nearly three-year spate of reading law-enforcement memoirs and books about urban policing while researching my own book, A Burglar’s Guide to the City. The excellent Ghettoside by Jill Leovy came out at the very end of that peculiar literary diet—but it also showed up the rest of those books quite handily.

Ghettoside is bracing, sympathetic, and emotionally nuanced in its week-by-week portrayal of LAPD homicide detectives investigating the murder of a fellow detective’s teenage son. Much larger than this, however, is Leovy’s dedication throughout the book to sorting through the overlapping mazes of media disinformation that have turned “black-on-black” crime into nothing more than a dismissive explanation of something genuinely horrific, a way to paper-over “racist interpretations of homicide statistics,” in reviewer Hari Kunzru’s words. More damningly, Ghettoside insists, this ongoing wave of murders and revenge-killings is not some new urban state of nature, but is entirely capable of being stopped.

Indeed, Leovy clearly and soberly shows through years of L.A. homicide reporting that today’s epidemic of violence primarily targeting African-American males is due to a failure of law enforcement—or, in her words, “where the criminal justice system fails to respond vigorously to violent injury and death, homicide becomes endemic.” Yet the answer, she explains, is more policing, not less. As an endorsement of effective, community-centered police work, the book is unparalleled.

No matter what side you think you might be on in the growing—and entirely unnecessary—divide between police and the populace they are hired to serve, this is a superb guide to the complexities of law enforcement in contemporary Los Angeles and, by extension, in every American metropolis.

14) The City That Never Was by Christopher Marcinkoski (Princeton Architectural Press)

Christopher Marcinkoski’s book is a fascinating exploration of the relationships between “volatile fiscal events” and “speculative urbanization,” with a specific focus on a cluster of failed urban projects in Spain. Marcincoski defines speculative urbanization as “the construction of new urban infrastructure or settlement for primarily political or economic purposes, rather than to meet real (as opposed to artificially projected) demographic or market demand.”

Although the author jokes that his book is actually quite late to the conversation—discussing the spatial fallout of a global financial crisis that was already five years old by the time he began writing—it is actually a remarkably timely study, as well as a sad assessment of how easily architectural production can become ensnared in economic forces far more powerful than humanism or design.

15) Slow Manifesto: Lebbeus Woods Blog edited by Clare Jacobson (Princeton Architectural Press)

Lebbeus Woods was both a friend and a personal hero of mine; his blog, which lasted from 2007 to shortly before his death in 2012, has now been collated, edited, and preserved by Princeton Architectural Press, with more than 300 individual entries. While primarily text, the books also includes several black-and-white images, including pages from his otherworldly sketchbooks. Thoughts on “wild buildings,” war, borders, September 11th, the now also deceased designer Zaha Hadid, and Woods’s own intriguing mix of cinematic/fictional and analytic/documentary modes of writing abound.


16) Almost Nature by Gerco de Ruijter (Timmer Art Books)

I’ve written about Dutch photographer Gerco de Ruijter fairly extensively in the past—most recently in a piece about “grid corrections”—so I was thrilled to see that some of his aerial work has been collected in a new, beautifully realized edition. It collects photos of stabilized coastlines and tree farms, grids and borders.

“Is the wilderness wild?” an accompanying text by Dirk van Weelden asks. “Cities and industrial farming make it seem man is in perfect control,” van Weelden continues later in the essay. “The reality is far more interesting. (…) The truly uncontrollable forces of nature are mutation, chance, hybridity, and contamination,” all subjects de Ruijter’s photos document at various scales, in every season.

17) Niche Tactics: Generative Relationships Between Architecture and Site by Caroline O’Donnell (Routledge)

In the guise of what looks—and even, to some extent, physically feels—like a textbook there is hidden a fantastic study of how buildings relate to their surroundings.

More precisely, Caroline O’Donnell’s investigation of “architecture and site” hopes to reveal how, during the design process, the context of a building affects that building’s final form. Questions of autonomy (do buildings need to reflect or refer to their settings at all?) and generation (can the essence of a site be “extracted” to give shape to the final building?) are woven through a series of essays about ugliness, architectural history, colonialism, monstrosity, and more.

18) How to Thrive in the Next Economy: Designing Tomorrow’s World Today by John Thackara (Thames & Hudson)

John Thackara is already widely known for his advocacy of “sustainability” in design—a word I deliberately put in scare-quotes because Thackara himself would prefer, I presume, a term more like transformative or even revolutionary design. That is, design that can flip the world on its head, not through violence, but through unexpected and strategic solutions to problems that often remain undiagnosed or overlooked. This new, short book looks at everything from mass transit to internet access, clothing manufacture to desertification, aging to fresh water, seeking nothing less than “a new concept of the world.” “The core value of this emerging economy is stewardship,” he writes, “rather than extraction.”

19) Design and Violence edited by Paola Antonelli and Jamer Hunt (Museum of Modern Art)

This book, crisply designed by Shaz Madani, documents an exhibition and debate series of the same name hosted by the Museum of Modern Art. Presented here as a combination of short essays by various authors—myself included—and provocative design objects, products, and public events, the aim is both to startle and to moderate. That is, the book seeks to bring together conflicting sides of often quite fierce arguments about the role of design, including how design can be used to mitigate or even, on occasion, to perpetuate violence. There are 3D-printed guns and a short history of the AK-47 alongside examples of prison architecture, classified surveillance aircraft, slaughterhouse diagrams, and border walls, to name but a few.

Finally, although I have mentioned it many times before, I do also have a new book of my own that just came out last week, called A Burglar’s Guide to the City; if you’d prefer to sample the goods before purchasing, however, you can check out an excerpt in The New York Times Magazine. But please consider supporting BLDGBLOG by ordering a copy—not least because then we can talk about burglary, architecture, and heists…

shanghaishift[Image: The same point in Shanghai, shifted between its map and satellite view; via Google Maps].

The slippage between map and territory is made unsettlingly clear by a mandatory geographic offset introduced into digital cartography products operating in China.

Variously known as “_applyChinaLocationShift,” eviltransform, the “China GPS Offset Problem,” and, most interestingly, as “Mars Coordinates,” this algorithmic shifting of GPS coordinates is related to China’s official mapping and survey rules, devised for national and economic security.

I’ve written much more about this in a new article for Travel + Leisure, where everything from trap streets to Jorge Luis Borges gets involved, as well as questions of technology, international borders, and geopolitics. Check it out, and let me know if you’ve had any experience with the issue yourself.

Subterranean Lightning Brigade

[Image: “Riggers install a lightning rod” atop the Empire State Building “in preparation for an investigation into lightning by scientists of the General Electric Company” (1947), via the Library of Congress].

This is hardly news, but I wanted to post about the use of artificial lightning as a navigational aid for subterranean military operations.

This was reported at the time as a project whose goal was “to let troops navigate about inside huge underground enemy tunnel complexes by measuring energy pulses given off by lightning bolts,” where those lightning bolts could potentially be generated on-demand by aboveground tactical strike teams.

Such a system would replace the use of GPS—whose signals cannot penetrate into deep subterranean spaces—and it would operate by way of sferics, or radio atmospheric signals generated by electrical activity in the sky.

The proposed underground navigational system—known as “Sferics-Based Underground Geolocation” or S-BUG—would be capable of picking up these signals even from “hundreds of miles away. Receiving signals from lighting strikes in multiple directions, along with minimal information from a surface base station also at a distance, could allow operators to accurately pinpoint their position.” They could thus maneuver underground, even in hundreds—thousands—of feet below the earth’s surface in enemy caves or bunkers.

Hundreds of miles is a very wide range, of course—but what if there is no natural lightning in the area?

Enter artificial military storm generators, or the charge of the lightning brigade.

Back in 2009, DARPA also put out of a request for proposals as part of something called Project Nimbus. NIMBUS is “a fundamental science program focused on obtaining a comprehensive understanding of the lightning process.” However, it included a specific interest in developing machines for “triggering lightning”:

Experimental Set-up for Triggering Lightning: Bidders should fully describe how they would attempt to trigger lightning and list all potential pieces of equipment necessary to trigger lightning, as well as the equipment necessary to measure and characterize the processes governing lightning initiation, propagation, and attachment.

While it’s easy enough to wax conspiratorial here about future lightning weapons or militarized storm cells—after all, DARPA themselves write that they want to understand “how [lightning] ties into the global charging circuit,” as if “the global charging circuit” is something that could be instrumentalized or controlled—I actually find it more interesting to speculate that generating lightning would be not for offensive purposes at all, but for guiding underground navigation.

[Image: Lightning storm over Boston; via Wikimedia/NOAA].

Something akin to a strobe light begins pulsing atop a small camp of unmarked military vehicles parked far outside a desert city known for its insurgent activities. These flashes gradual lengthen, both temporally and physically, lasting longer and stretching upward into the sky; the clouds above are beginning to thicken, grumbling with quiet rolls of thunder.

Then the lightning strikes begin—but they’re unlike any natural lightning you’ve ever seen. They’re more like pops of static electricity—a pulsing halo or toroidal crown of light centered on the caravan of trucks below—and they seem carefully timed.

To defensive spotters watching them through binoculars in the city, it’s obvious what this means: there must be a team of soldiers underground somewhere, using artificial sferics to navigate. They must be pushing forward relentlessly through the sewers and smuggling tunnels, crawling around the roots of buildings and maneuvering through the mazework of infrastructure that constitutes the city’s underside, locating themselves by way of these rhythmic flashes of false lightning.

Of course, this equipment would eventually be de-militarized and handed down to the civilian sector, in which case you can imagine four friends leaving REI on a Friday afternoon after work with an artificial lightning generator split between them; no larger than a camp stove, it would eventually be set up with their other weekend caving equipment, used to help navigate through deep, stream-slick caves an hour and a half outside town, beneath tall mountains where GPS can’t always be trusted.

Or, perhaps fifty years from now, salvage teams are sent deep into the flooded cities of the eastern seaboard to look for and retrieve valuable industrial equipment. They install an artificial lightning unit on the salt-bleached roof of a crumbling Brooklyn warehouse before heading off in a small armada of marsh boats, looking for entrances to old maintenance facilities whose basement storage rooms might have survived rapid sea-level rise.

Disappearing down into these lost rooms—like explorers of Egyptian tombs—they are guided by bolts of artificial lightning that spark upward above the ruins, reflected by tides.

Or—why not?—perhaps we’ll send a DARPA-funded lightning unit to one of the moons of Jupiter and let it flash and strobe there for as long as it needs. Called Project Miller-Urey, its aim is to catalyze life from the prebiotic, primordial soup of chemistry swirling around there in the Cthulhoid shadow of eternal ice mountains.

Millions and millions of years hence, proto-intelligent lifeforms emerge, never once guessing that they are, in fact, indirect descendants of artificial lightning technology. Their spark is not divine but military, the electrical equipment that sparked their ancestral line long since fallen into oblivion.

In any case, keep your eyes—and cameras—posted for artificial lightning strikes coming to a future military theater near you…

Ghosts of Home Geography

Noted scam artist and “Facebook fugitive” Paul Ceglia, hoping to escape from a recently imposed state of house-arrest, “sliced off his GPS ankle monitor and affixed it to a crudely built contraption in his rural New York residence,” Ars Technica reports.

The GPS sensor’s subsequent movements were then meant to maintain the illusion that he was still at home.

[Image: The GPS contraption; photo via Ars Technica].

According to the U.S. Marshals, “While conducting a security sweep of the home, the Task Force Officers observed, among other things, a hand-made contraption connected to the ceiling, from which Ceglia’s GPS bracelet was hanging. The purpose of the contraption appeared to be to keep the bracelet in motion using a stick connected to a motor that would rotate or swing the bracelet.”

The “contraption” appears to have been almost laughably basic, but it’s not hard to imagine something more ambitious, complete with tracks wandering from room to room to make it appear that someone is truly inside the residence.

In fact, the idea of faking your own location through attaching your GPS anklet to a Roomba, for example, and letting it wander around the house all day is perversely brilliant, like something from a 21st-century Alfred Hitchcock film. Of course, it wouldn’t take very long to deduce from the algorithmically perfect straight lines and zig-zag edge geometry of your Roomba’s movements that it is not, in fact, a real person walking around in there—or perhaps it would just look like you’ve taken up some bizarre new form of home exercise.

But a much more believable algorithm for faking the movements of a real, living resident could be part of some dark-market firmware update—new algorithms for the becoming-criminal of everyday machines.

A whole new class of products could be devised: part burglar deterrent, part anti-police-tracking device, they would meander and bump their way through a home’s interior, creating the geographic illusion that someone is moving around in there, passing room to room at certain moments.

It would be a GPS surrogate or implied resident, a locational ghost built from satellite signals and semi-autonomous robotic machines.

The Electromagnetic Fortification of the Suburbs

[Image: A drone from DJI].

It’s hardly surprising to read that drones can be repurposed as burglars’ tools; at this point, take any activity, add a drone, and you, too, can have a news story (or Kickstarter) dedicated to the result.

“Why not send an inexpensive drone, snoop in your windows, see if you have any pets, see if you have any expensive electronics, maybe find out if you have any jewelry hanging around,” a security expert wonders aloud to Hawaii’s KITV, describing what he sees as the future of burglary. Burglars “can do all that with a drone without ever stepping a foot on your property line.”

“So what’s a homeowner to do?” the TV station asks.

They suggest following the drone back to its owner, who, due both to battery life and signal range, will be nearby; or even installing “new expensive high-tech drone detection systems that claim to detect the sounds of a drone’s propellers.” This is absurd—suggesting that some sort of drone alarm will go off at 3am, driving you out of bed—but it’s such a perfectly surreal vision of the suburbs of tomorrow.

Fortifying our homes against drone incursion will be the next bull market in security: whole subdivisions designed to thwart drone flights, marketed to potential homeowners specifically for that very reason.

You go home for the weekend to visit your parents where, rather than being enlisted to mow the lawn or clean the gutters, you’re sent you out on drone duty, installing perimeter defenses or some sort of jamming blanket, an electromagnetically-active geotextile disguised beneath the mulch. Complex nets and spiderweb-like antennas go on sale at Home Depot, perfect for snaring drone rotors and leading to an explosion in suburban bird deaths.

[Image: A drone from DJI].

This news comes simultaneously with a story in Forbes, where we read that drone manufacturer DJI is implementing a GPS block on its products: they will no longer be able to fly within 15.5 miles of the White House.

The company is issuing “a mandatory firmware update to all Phantom drones that will restrict flight within a 15.5 mile radius centered around downtown Washington D.C. Pilots looking to operate their Phantom drone will not be able to take off or fly within the no-fly-zone.”

Based off a drone’s GPS coordinates, the technology to geo-fence drones from entering a particular airspace, especially around major airports, has been around in Phantoms since early last year. The new update will add more airports to its no-fly-zone database as the 709 no-fly-zones already in the Phantom’s flight controller software will expand to more than 10,000, with additional restrictions added to prevent flight across national borders.

This is remarkable for a number of reasons, not the least of which is the fact that firmware updates and geography now work together to disable entire classes of products within a given zone or GPS range. Put another way, drones today—but what tomorrow?

Geofencing or “locationized” firearms have already been discussed as a possible future form of gun control, for example, and it would not be at all surprising to see “locationized” smartphones or geofenced cameras becoming a thing in the next few years.

All a government (or criminal syndicate) would have to do is release a (malicious) firmware update, temporarily shutting down certain types of electronics within range of, say, a presidential inauguration (or a bank heist).

[Image: A drone from DJI].

More to the point of this post, however, GPS-based geofencing will also become part of the electromagnetic armature of future residential developments, a new, invisible layer of security for those who are willing to pay for it.

Think, for example, of the extraordinary geographic dazzle effects used by government buildings to camouflage their real-world locations: as Dana Priest and William Arkin wrote for The Washington Post back in 2012, “most people don’t realize when they’re nearing the epicenter of Fort Meade’s, even when the GPS on their car dashboard suddenly begins giving incorrect directions, trapping the driver in a series of U-turns, because the government is jamming all nearby signals.”

If half the point of living in the suburbs is to obtain a certain level of privacy, personal safety, and peace of mind, then it is hardly science fiction to suggest that the electromagnetic fortification of suburbia is on the immediate horizon.

You won’t just turn on a burglar alarm with your handy smartphone app; you’ll also switch on signal-jamming networks hidden in the trees or a location-scrambling geofence camouflaged as a garden gnome at the edge of your well-mown lawn. Drones, dazzled by invisible waves of unpredictable geographic information, will perform U-turns or sudden dives, even racing off to a pre-ordained security cage where they can be pulled from the air and disabled.

The truly high-end residential developments of tomorrow will be electromagnetically fortified, impervious to drones, and, unless you’ve been invited there, impossible for your cars and cellphones even to find.

Glitches in Spacetime, Frozen into the Built Environment

Back in the summer of 2012, Nicola Twilley and I got to visit the headquarters of GPS, out at Schriever Air Force Base in Colorado.

[Image: Artist’s rendering of a GPS satellite, via Wikipedia].

“Masters of Space”

Over the course of a roughly two-hour visit, we toured, among other things, the highly secure, windowless office room out of which the satellites that control GPS are monitored and operated. Of course, GPS–the Global Positioning System—is a constellation of 32 satellites, and it supplies vital navigational information for everything from smartphones, cars, and construction equipment to intercontinental missiles.

It is “the world’s largest military satellite constellation,” Schriever Air Force Base justifiably boasts.

For somewhat obvious reasons, Nicola and I were not allowed to bring any audio or video recording devices into the facility (although I was able to take notes), and we had to pass through secure checkpoint after secure checkpoint on our way to the actual room. Most memorable was the final door that led to the actual control room: it was on a 15-second emergency response, meaning that, if the door stayed open for more than 15 seconds, an armed SWAT team would arrive to see what was wrong.

When we got inside the actual office space, the lights were quite low and at least one flashing red light reminded everyone inside that civilians were now present; this meant that nothing classified could be discussed. Indeed, if anyone needed to hop on the telephone, they first needed to shout, “Open line!” to make sure that everyone knew not to discuss classified information, lest someone on the other end of the phonecall might hear.

Someone had even made a little JPG for us, welcoming “Geoff Manaugh and Nicola Twilley” to the GPS HQ, and it remained on all the TV monitors while we were there inside the space.

Surreally, in a room without windows, a group of soldiers who, on the day we visited, were all-male and looked no more than 23 or 24 years old, wore full military camouflage, despite the absence of vegetation to blend into, as they controlled the satellites.

At one point, a soldier began uploading new instructions to the satellites, and we watched and listened as one of those artificial stars assumed its new place in the firmament. What would Giordano Bruno have made of such a place?

This was the room behind the curtain, so to speak, a secure office out of which our nation’s surrogate astronomy is maintained and guided.

Appropriately, they call themselves “Masters of Space.”

[Image: A “Master of Space” badge from Schriever Air Force Base].

In any case, I mention all this for at least two reasons:

A 50,000km-Wide Dark Matter Detector

Edge to edge, the GPS constellation can apparently be considered something of a single device, a massive super-detector whose “time glitches” could be analyzed for signs of dark matter.

As New Scientist explained last month, “The network of satellites is about 50,000 kilometers in diameter, and is traveling through space—along with the entire solar system—at about 300 kilometers a second. So any time shift when the solar system passes through a cosmic kink will take a maximum of 170 seconds to move across network.”

The temporal distortion—a kind of spacetime wave—would propagate across the constellation, taking as long as 170 seconds to pass from one side to the other, leaving forensically visible traces in GPS’s navigational timestamps.

The very idea of a 50,000-kilometer wide super-device barreling through “cosmic kinks” in spacetime is already mind-bogglingly awesome, but add to this the fact that the “device” is actually an artificial constellation run by the U.S. military, and it’s as if we are all living inside an immersive, semi-weaponized, three-dimensional spacetime instrument, sloshing back and forth with 170-second-long tides of darkness, the black ropes of spacetime being strummed by the edges of a 32-point star.

Even better, those same cosmic kinks could theoretically show up as otherwise imperceptible moments of locational error on your own smartphone. This would thus enlist you, against your knowledge, as a minor relay point in a dark matter detector larger than the planet Earth.

The Architectural Effects of Space Weather

While Nicola and I were out at the GPS headquarters in Colorado, one of the custodians of the constellation took us aside to talk about all the various uses of the navigational information being generated by the satellites—including, he pointed out, how they worked to mitigate or avoid errors.

Here, he specifically mentioned the risk of space weather affecting the accuracy of GPS—that is, things like solar flares and other solar magnetic events. These can throw-off the artificial stars of the GPS constellation, leading to temporarily inaccurate location data—which can then mislead our construction equipment here on Earth, even if only by a factor of millimeters.

What’s so interesting and provocative about this is that these tiny errors created by space weather risk becoming permanently inscribed into the built environment—or fossilized there, in a sense, due to the reliance of today’s construction equipment on these fragile signals from space.

That 5mm shift in height from one pillar to the next would thus be no mere construction error: it would be architectural evidence for a magnetic storm on the sun.

Take the Millau Viaduct—just one random example about which I happen to have seen a construction documentary. That’s the massive and quite beautiful bridge designed by Foster + Partners, constructed in France.

[Image: The Millau Viaduct, courtesy of Foster + Partners].

The precision required by the bridge made GPS-based location data indispensable to the construction process: “Altimetric checks by GPS ensured a precision of the order of 5mm in both X and Y directions,” we read in this PDF.

But even—or perhaps especially—this level of precision was vulnerable to the distorting effects of space weather.

Evidence of the Universe

I have always loved this quotation from Earth’s Magnetism in the Age of Sail, by A.R.T. Jonkers:

In 1904 a young American named Andrew Ellicott Douglass started to collect tree specimens. He was not seeking a pastime to fill his hours of leisure; his motivation was purely professional. Yet he was not employed by any forestry department or timber company, and he was neither a gardener not a botanist. For decades he continued to amass chunks of wood, all because of a lingering suspicion that a tree’s bark was shielding more than sap and cellulose. He was not interested in termites, or fungal parasites, or extracting new medicine from plants. Douglass was an astronomer, and he was searching for evidence of sunspots.

Imagine doing the same thing as Andrew Ellicott Douglass, but, instead of collecting tree rings, you perform an ultra-precise analysis of modern megastructures that were built using machines guided by GPS.

You’re not looking for lost details of architectural history. You’re looking for evidence of space weather inadvertently preserved in titanic structures such as the Millau Viaduct.

[Image: The Millau Viaduct, courtesy of Foster + Partners].

Fossils of Spacetime

If you take all of this to its logical conclusion, you could argue that, hidden in the tiniest spatial glitches of the built environment, there is evidence not only of space weather but even potentially of the solar system’s passage through “kinks” and other “topological defects” of dark matter, brief stutters of the universe now fossilized in the steel and concrete of super-projects like bridges and dams.

New Scientist points out that a physicist named Andrei Derevianko, from the University of Nevada at Reno, is “already mining 15 years’ worth of GPS timing data for dark matter’s fingerprints,” hoping to prove that GPS errors do, indeed, reveal a deeper, invisible layer of the universe—but how incredibly interesting would it be if, somehow, this same data could be lifted from the built environment itself, secretly found there, inscribed in the imprecisions of construction equipment, perhaps detectable even in the locational drift as revealed by art projects like the Satellite Lamps of Einar Sneve Martinussen, Jørn Knutsen, and Timo Arnall?

The bigger the project, the more likely its GPS errors could be read or made visible—where unexpected curves, glitches, changes in height, or other minor inaccuracies are not just frustrating imperfections caused by inattentive construction engineers, but are actually evidence of spacetime itself, of all the bulging defects and distortions through which our planet must constantly pass now frozen into the built environment all around us.

Drive-By Archaeology

[Image: From a patent filed by MIT, courtesy U.S. Patent and Trademark Office].

The technical systems by which autonomous, self-driving vehicles will safely navigate city streets are usually presented as some combination of real-time scanning and detailed mnemonic map or virtual reference model created for that vehicle.

As Alexis Madrigal has written for The Atlantic, autonomous vehicles are, in essence, always driving within a virtual world—like Freudian machines, they are forever unable to venture outside a sphere of their own projections:

The key to Google’s success has been that these cars aren’t forced to process an entire scene from scratch. Instead, their teams travel and map each road that the car will travel. And these are not any old maps. They are not even the rich, road-logic-filled maps of consumer-grade Google Maps.
They’re probably best thought of as ultra-precise digitizations of the physical world, all the way down to tiny details like the position and height of every single curb. A normal digital map would show a road intersection; these maps would have a precision measured in inches.

The vehicle can thus respond to the city insofar as its own spatial expectations are never sufficiently contradicted by the evidence at hand: if the city, as scanned by the vehicle’s array of sensors and instruments, corresponds to the vehicle’s own internal expectations, then it can make the next rational decision (to turn a corner, stop at an intersection, wait for a passing train, etc.).

However, I was very interested to see that an MIT research team led by Byron Stanley had applied for a patent last autumn that would allow autonomous vehicles to guide themselves using ground-penetrating radar. It is the subterranean realm that they would thus be peering into, in addition to the plein air universe of curb heights and Yield signs, reading the underworld for its own peculiar landmarks.

[Image: From a patent filed by MIT, courtesy U.S. Patent and Trademark Office].

How would it work? Imagine, the MIT team suggests, that your autonomous vehicle is either in a landscape blanketed in snow. It is volumetrically deformed by all that extra mass and thus robbed not only of accurate points of measurement but also of any, if not all, computer-recognizable landmarks. Or, he adds, imagine that you have passed into a “GPS-denied area.”

In either case, you and your self-driving vehicle run the very real risk of falling off the map altogether, stuck in a machine that cannot find its way forward and, for all intents and purposes, can no longer even tell road from landscape.

[Image: From a patent filed by MIT, courtesy U.S. Patent and Trademark Office].

Stanley’s group has thus come up with the interesting suggestion that you could simply give autonomous vehicles the ability to see through the earth’s surface and scan for recognizable systems of pipework or other urban infrastructure down below. Your vehicle could then just follow those systems through the obscuring layers of rain, snow, or even tumbleweed to its eventual destination.

These would be cars attuned to the “subsurface region,” as the patent describes it, falling somewhere between urban archaeology and speleo-cartography.

In fact, with only the slightest tweaking of this technology and you could easily imagine a scenario in which your vehicle would more or less seek out and follow archaeological features in the ground. Picture something like an enormous basement in Rome or central London—or perhaps a strange variation on the city built entirely for autonomous vehicles at the University of Michigan. It is a vast expanse of concrete built—with great controversy—over an ancient site of incredible archaeological richness.

Climbing into a small autonomous vehicle, however, and avidly referring to the interactive menu presented on a touchscreen dashboard, you feel the vehicle begin to move, inching forward into the empty room. The trick is that it is navigating according to the remnant outlines of lost foundations and buried structures hidden in the ground around you, like a boat passing over shipwrecks hidden in the still but murky water.

The vehicle shifts and turns, hovers and circles back again, outlining where buildings once stood. It is acting out a kind of invisible architecture of the city, where its routes are not roads at all but the floor plans of old buildings and, rather than streets or parking lots, you circulate through and pause within forgotten rooms buried in the ground somewhere below.

In this “subsurface region” that only your vehicle’s radar eyes can see, your car finds navigational clarity, calmly poking along the secret forms of the city.

In any case, for more on the MIT patent, check out the U.S. Patent and Trademark Office.

Loop Geography as Defensive Tactic

In a fascinating detail from a long series of articles published two years ago in the Washington Post, recently expanded as a stand-alone book called Top Secret America, we learn about one way to hide classified government infrastructure in plain sight.

[Image: Photo by Michael S. Williamson, courtesy of The Washington Post].

“[J]ust outside Washington,” authors Dana Priest and William Arkin explain, in the exurbs of depopulated office parks and “huge buildings with row after row of opaque, blast-resistant windows,” there can be found what the authors describe as “the capital of an alternative geography of the United States, one defined by the concentration of top-secret government organizations and the companies that do work for them.”

One such complex, called Fort Meade, “is the largest of a dozen such clusters across the United States.”

And it is cleverly camouflaged:

The existence of these clusters is so little known that most people don’t realize when they’re nearing the epicenter of Fort Meade’s, even when the GPS on their car dashboard suddenly begins giving incorrect directions, trapping the driver in a series of U-turns, because the government is jamming all nearby signals.

It’s an experiential trap street—an infinite loop—a deliberate cartographic error introduced into the mapping of the world so as to sow detour and digression. A kind of digital baffling, or recursive geography as state defensive tactic.

I’m also curious when we might see this privatized and domesticated—gated communities, for instance, blocking the GPS navigation of their streets in the misguided belief that this will help protect them from future burglary, effectively delisting themselves from public cartographic records. Perhaps the future of neighborhood security lies in the privatized repurposing of advanced signal-jamming technology, the misleading lamination of other, false maps onto the streets as they really exist.
