There's a New Blackest Material Ever, and It's Eating a Diamond As We Speak



On the floor of the New York Stock Exchange, a team of artists and scientists have made a 16.78-carat diamond — valued at more than $2 million — disappear. 
Granted, denizens of the Stock Exchange are no strangers to making vast amounts of wealth vanish, but this time the scientists are doing the heavy lifting. Working with artist Diemut Strebe, a team of researchers from MIT covered the shimmering yellow diamond in a newly discovered type of carbon nanotube coating that turns 3D objects into black, almost 100% light-free voids. 
According to the researchers, who described the coating in a study published Sept. 12 in the journal ACS Applied Materials & Interfaces, this newfound nanotube structure is the blackest of black materials ever created, absorbing more than 99.996% of any light that touches it.
"Our material is 10 times blacker than anything that's ever been reported," lead study author Brian Wardle, a professor of aeronautics and astronautics at MIT, said in a statement
The team created the new coating accidentally, while trying to design an improved process for growing carbon nanotubes (essentially, microscopically small strings of carbon) on surfaces like aluminum foil. One problem with working with aluminum, they found, is that a layer of oxides formed whenever the surface was exposed to open air, creating a pesky chemical barrier between the nanotubes and the foil. To eliminate these oxides, the team soaked the foil in saltwater, then moved it into a small oven where the nanotubes could grow without oxygen interference. 
With millions of tangled nanotubes now studding the foil like a microscopic forest of fur, incoming photons of light got lost and had a very hard time exiting from the foil's surface. The foil, the team found, had thus turned completely black — so black, the ridges of the aluminum were completely invisible when viewed straight on.
"I remember noticing how black it was before growing carbon nanotubes on it, and then after growth, it looked even darker," study co-author Kehang Cui, a professor at Shanghai Jiao Tong University, said in the statement. "So, I thought I should measure the optical reflectance of the sample."
Cui and colleagues compared the reflectiveness of their new coating with other light-devouring nanostructures, including the previous record holder for darkness, Vantablack. While the differences between the various nanostructures are negligible to human eyes, the researchers found that their coating was indeed blacker than every other black they tested, no matter the angle at which light hit the coating.
The effect, as you can see in the image of the diamond above, is eerie. Once exposed to the coating, the brilliant yellow diamond seemingly loses all of its facets, flattening into what artist Diemut Strebe called "a kind of black hole" from which no light or shadows can escape. 
Incidentally, this uberdark coating could one day be used to help astronomers see actual black holes, by applying the material to telescope-mounted shades that help reduce glare from the stars. For now, though, you can see the diamond-shaped void for yourself at the New York Stock Exchange until Nov. 25.

Being messy on the inside keeps metamaterials from folding under stress



Human-made metamaterials with messy internal designs may be more resistant to damage than those with neatly patterned structures.
Metamaterial lattices, usually composed of struts that form identical, repeating “unit cells,” can exhibit properties that normal solids don’t (SN: 1/19/19, p. 5). But under heavy loads, overstressed struts can collapse, and that breakage quickly splinters through the whole grid, causing it to crumble.
Materials scientist Minh-Son Pham of Imperial College London and colleagues realized that this kind of collapse is similar to the way metallic crystals with atoms arranged in identical unit cells deform under heavy loads. In these materials, defects in the crystal can travel freely through its atomic lattice like dominoes falling in a row, weakening the crystal (SN: 9/11/10, p. 22).
To create more resilient metamaterials, Pham and colleagues drew inspiration from the irregular atomic arrangements inside crystalline metals. In these materials, described in the Jan. 17 Nature, different regions contain unit cells with different orientations, sizes or types of crystals. The boundaries between these regions serve as roadblocks to stop defects from moving. Metamaterial lattices patterned after these atomic setups could make more reliable components for cars and airplanes, Pham says.
Pham’s team 3-D printed lattices with unit cells arranged either in perfect order, as in conventional metamaterials, or in motley groups of different atomic structures. When the researchers squeezed lattices between metal plates, the mixed lattices proved sturdier than those with regular unit cell arrangements.

TIMEFULNESS: A GEOLOGIST'S STORY. INTERVIEW WITH MARCIA BJORNERUD





Geologist Marcia Bjornerud’s latest book, Timefulness: How Thinking Like a Geologist Can Help Save the World, can easily capture your inner philosopher, scientist, activist, and writer. When I received this book from Princeton University Press, I was immediately intrigued by the book’s cover. I’ve always been fascinated by ideas that necessarily mix up life’s ingredients into creative nature stories, and this book does just that. The choice of title and cover design (with its elegant series of mineralogy lithographs) offers clues to the layered Earth-story within: unwrapping the scientific ways of knowing our home’s deep planetary history; how we humans have come to discover these stories; how knowing them can re-educate us and thus drive us to become better citizens as part of the whole community of life

Bjornerud’s title, Timefulness, intrigued me as a grander understanding of our current temporal limitations. The subtitle, “Thinking Like a Geologist Can Help Save the World,” shares how looking into the deep time of Earth’s rocks breaks open an opportunity for us to become more aware of the damage we have done while concurrently offering hope. Bjornerud offers tips on re-imagining how we can comprehend our humanness on this planet by coming to re-know ourselves as Earthlings. Marcia Bjornerud’s Earth story elaborates this interweaving of a deep past with a deeper future and explores how we might expand our human sense of temporal directions in order to arrive at some meaningful place of resilience.

Anja Claus (AC): In Timefulness, you breathed great life into this magical story of rocks; that’s a big feat in our flashy, fast-paced, capitalist culture.
Marcia Bjornerud (MB): In most people’s minds rocks are dumb, mute, and dull perhaps. So I tried to bring them back to life and share the stories that they have to tell us.
AC: In a way, your book is a storytelling of Earth—Earth’s past but also its now. You say in your book, “The dramatic narratives of the geologic past are perfectly suited to the human appetite for storytelling.” Why do you think that? What is it that makes for such good storytelling?
MB: I’m positioning the idea of storytelling in contrast to the physical, pure sciences of physics and chemistry, which are of course important fields—and I am partly trained myself as a physicist. But what’s lacking in them is this sense of narrative arc. The triumph of physics is that it has distilled out these universal, timeless laws and rules. But if something is timeless, there’s no story to really tell. There’s no character development.
Earth as a whole system has had a very interesting series of personalities, in a sense. It’s had a childhood, an adolescence, a middle-age. It’s seen cataclysm and wonderful, bountiful times as well. So that’s what I mean. That there are stories in the natural world, and they match our appetite for seeing how things unfold. I think that’s the way to draw people in: Tell these Earth stories, develop some kind of relationship with the protagonist, and they’re hooked.

Critical Zones. Observatories for Earthly Politics



Frédérique Aït-Touati, Alexandra Arènes, Axelle Gérgoire, The Soil Map (detail), Terra Forma, manuel de cartographies potentielles, 2019. © the artists.
By now everybody knows that there is an existential threat to our collective conditions of existence, but very few people have any idea of how to cope with this new Critical situation. It is very strange, but citizens of many developed countries are disoriented; it is as if they were asked to land on a new territory, an Earth that they have long ignored having reacted to their action. The hypothesis we want to propose is that the best way to map this new Earth is to see it as a network of Critical Zones, which constitute a thin skin a few kilometers thick that has been generated over eons of time by life forms. Those life forms had completely transformed the original geology of the Earth, before humanity transformed it yet again over the last centuries.
Over the years, scientists have installed multiple Observatories to study these Critical Zones and have made us aware of the complex composition and extreme fragility of this thin layer inside which all life forms, humans included, have to cohabit. They have renewed Earth science in a thousand ways and very much in a way that Alexander von Humboldt would have approved. Increasingly, scientists, artists, activists, politicians, and citizens are realizing that society is not centered solely on humanity, but it has to become Earthly again if it wishes to land without crashing. The modern project has been in flight, unconcerned by planetary limits. Suddenly, there is a general movement toward the soil and new attention to the ways people might inhabit it. Politics is no longer about humans making decisions on their own and for themselves only, but has become an immensely more complex undertaking. New forms of citizenship and new types of attention and care for life forms are required to generate a common ground.
The ZKM thus continues the comprehensive engagement and collaboration with local communities and institutions that was explored during the Open Codes exhibition (2017–2019), opening up a space for common action and discussion to recompose the world we live in: Over a period of five months ZKM will host an exhibition conceived as a scale model to simulate the spatial novelty of this new land as well as the diversity of relations between the life forms inhabiting it. It will serve as an Observatory of Critical Zones allowing visitors to familiarize themselves with the new situation. This special combination of thought experiment and exhibition was developed by Peter Weibel and Bruno Latour in their previous collaborations at ZKM. Iconoclash in 2002, Making Things Public in 2005, and Reset Modernity! in 2016 constitute the three former “thought exhibitions” (Gedankenausstellungen) that resulted from their intensive working relationship which now spans 20 years.
The ZKM website will soon publish the intense program accompanying the exhibition. We invite thinkers and scholars, activists and initiatives from all over the world to share and discuss ideas—please contact us at hellocriticalzones [​at​] zkm.de.

When Whales and Humans Talk

When Whales and Humans Talk




Sometime in the late 19th century, an Iñupiaq carver fashioned this amulet for an umiak out of driftwood, carving the likeness of a bowhead whale, its blowhole symbolized with a piece of obsidian. As with other whaling amulets Erica Hill has examined, this object may have also functioned as part of the boat’s structure. Photo by Department of Anthropology, Smithsonian Institute (Cat. A347918)
Harry Brower Sr. was lying in a hospital bed in Anchorage, Alaska, close to death, when he was visited by a baby whale.
Although Brower’s body remained in Anchorage, the young bowhead took him more than 1,000 kilometers north to Barrow (now Utqiaġvik), where Brower’s family lived. They traveled together through the town and past the indistinct edge where the tundra gives way to the Arctic Ocean. There, in the ice-blue underwater world, Brower saw Iñupiat hunters in a sealskin boat closing in on the calf’s mother.
Brower felt the shuddering harpoon enter the whale’s body. He looked at the faces of the men in the umiak, including those of his own sons. When he awoke in his hospital bed as if from a trance, he knew precisely which man had made the kill, how the whale had died, and whose ice cellar the meat was stored in. He turned out to be right on all three counts.
Brower lived six years after the episode, dying in 1992 at the age of 67. In his final years, he discussed what he had witnessed with Christian ministers and Utqiaġvik’s whaling captains. The conversations ultimately led him to hand down new rules to govern hunting female whales with offspring, meant to communicate respect to whales and signal that people were aware of their feelings and needs. “[The whale] talked to me,” Brower recalls in a collection of his stories, The Whales, They Give Themselves. “He told me all the stories about where they had all this trouble out there on the ice.”
Not long ago, non-Indigenous scientists might have dismissed Brower’s experience as a dream or the inchoate ramblings of a sick man. But he and other Iñupiat are part of a deep history of Arctic and subarctic peoples who believe humans and whales can talk and share a reciprocal relationship that goes far beyond that of predator and prey. Today, as Western scientists try to better understand Indigenous peoples’ relationships with animals—as well as animals’ own capacity for thoughts and feelings—such beliefs are gaining wider recognition, giving archaeologists a better understanding of ancient northern cultures.
“If you start looking at the relationship between humans and animals from the perspective that Indigenous people themselves may have had, it reveals a rich new universe,” says Matthew Betts, an archaeologist with the Canadian Museum of History who studies Paleo-Eskimo cultures in the Canadian Arctic. “What a beautiful way to view the world.”

Pattern Radio: Whale Songs

Pattern Radio: Whale Songs

Hello! A few of us at Google, in collaboration with research oceanographer Ann Allen at National Oceanic and Atmospheric Administration (NOAA) Pacific Islands Fisheries Science Center (PIFSC), created a website called Pattern Radio: Whale Songs. We put this post together to help answer questions about the project. Many thanks to our collaborators — the scientists, musicians, and educators who inspired us and taught us so much. If you have a question that’s not answered here, feel free to drop us a line at patternradio-support@google.com.

Childhood's End The digital revolution isn’t over but has turned into something else

Childhood's End

The digital revolution isn’t over but has turned into something else


All revolutions come to an end, whether they succeed or fail.
The digital revolution began when stored-program computers broke the distinction between numbers that mean things and numbers that do things. Numbers that do things now rule the world. But who rules over the machines?Once it was simple: programmers wrote the instructions that were supplied to the machines. Since the machines were controlled by these instructions, those who wrote the instructions controlled the machines.
Two things then happened. As computers proliferated, the humans providing instructions could no longer keep up with the insatiable appetite of the machines. Codes became self-replicating, and machines began supplying instructions to other machines. Vast fortunes were made by those who had a hand in this. A small number of people and companies who helped spawn self-replicating codes became some of the richest and most powerful individuals and organizations in the world.
Then something changed. There is now more code than ever, but it is increasingly difficult to find anyone who has their hands on the wheel. Individual agency is on the wane. Most of us, most of the time, are following instructions delivered to us by computers rather than the other way around. The digital revolution has come full circle and the next revolution, an analog revolution, has begun. None dare speak its name.Childhood’s End was Arthur C. Clarke’s masterpiece, published in 1953, chronicling the arrival of benevolent Overlords who bring many of the same conveniences now delivered by the Keepers of the Internet to Earth. It does not end well.

On the mineralogy of the “Anthropocene Epoch”


The “Anthropocene Epoch” has been proposed as a new post-Holocene geological time interval—a period characterized by the pervasive impact of human activities on the geological record. Prior to the influence of human technologies, the diversity and distribution of minerals at or near Earth’s surface arose through physical, chemical, and/or biological processes. Since the advent of human mining and manufacturing, particularly since the industrial revolution of the mid-eighteenth century, mineral-like compounds have experienced a punctuation event in diversity and distribution owing to the pervasive impact of human activities. We catalog 208 mineral species approved by the International Mineralogical Association that occur principally or exclusively as a consequence of human processes. At least three types of human activities have affected the diversity and distribution of minerals and mineral-like compounds in ways that might be reflected in the worldwide stratigraphic record. The most obvious influence is the widespread occurrence of synthetic mineral-like compounds, some of which are manufactured directly for applications (e.g., YAG crystals for lasers; Portland cement) and others that arise indirectly (e.g., alteration of mine tunnel walls; weathering products of mine dumps and slag). A second human influence on the distribution of Earth’s near-surface minerals relates to large-scale movements of rocks and sediments—sites where large volumes of rocks and minerals have been removed. Finally, humans have become relentlessly efficient in redistributing select natural minerals, such as gemstones and fine mineral specimens, across the globe. All three influences are likely to be preserved as distinctive stratigraphic markers far into the future.

The science of the inconceivable

A different kind of logic

by Philip Ball

Late last year, an experiment carried out by scientists at the Delft University of Technology in the Netherlands appeared to demonstrate that one object can affect another from afar without any physical interaction between the two. The finding confirmed an idea so extraordinary that, nearly a century ago, Albert Einstein had rejected it with the dismissive phrase “spooky action at a distance.” In quantum theory this phenomenon is known as “entanglement,” and many physicists now regard it as the most profound and important characteristic of the physical world at the smallest scales, which quantum theory describes.

Quantum entanglement is a deeply counterintuitive idea, which seems to contradict human experience of the physical world at the most essential level. In the everyday (“classical”) physical realm, objects affect one another via some kind of contact. The tennis ball flies from the racquet when struck, and when it hits the window the glass will smash. Sure, “invisible forces” seem to act across space—magnetic and electrical attraction and repulsion, say. But in quantum theory these interactions arise from the passage of a particle—a photon of light—between the two interacting bodies. Meanwhile, Einstein showed that the Sun’s gravity corresponds to a distortion of space, to which distant objects such as Earth respond. It’s generally believed that in a quantum theory of gravity (which doesn’t yet exist), this picture will prove to be equivalent to the exchange of “gravity particles” or gravitons between the Sun and Earth.
But quantum entanglement bothered Einstein because it suggested that one particle could affect another even when there was no conceivable physical interaction between them. It didn’t matter if those particles were light years apart—measuring a property of one particle would, according to quantum theory, instantly affect the properties of the other. How could that be?

Response to R. Scott Bakker on transcendental phenomenology and BBT



There is nothing “outside” the natural order. In this sense, I am opposed to the transcendentalist’s move to remove Reason or the reflective understanding from physical reality. There is indeed a supernaturalist residue in much transcendental and phenomenological philosophy. This is why my project has always been to theorize “the natural order” as itself always already creative, aesthetic, interpretational, experiential (mine is a naturalized transcendental (Schelling’s “Nature is a priori”)). There is no “other” world from which the causal efficacy of our world derives. With our universe, the cause is internal to the effect, which is another way of saying our universe is primarily organic (with mechanism as a secondary appearance). This is why I follow Whitehead in the endeavor to construct an ontology of organism, wherein: 1) Physics is the study of the evolutionary development of particles, stars, galaxies, and other micro- and macro- organisms-in-ecologies; 2) Biology is the study of the evolutionary development of single cells, plants, and animals in their meso-cosmic ecologies; 3) Philosophy, anthropology, and theology are different aspects of the study of the evolutionary development of languages, myths, and ideas in their noetic ecologies. The organism-environment field becomes the metaphysical metaphor guiding our theorizing, rather than the machine.

Now, when I say “my project has always been to theorize…”, I should qualify that “theory” in the context of an open-ended, evolving cosmos such as ours can never pretend to certainty or finality. Theory is not the construction of a disinterested, reflective ego (at least, no valuable theory is). Theory always remains dependent on the speculative leap of some metaphor or another. Theory is imaginative construction requiring equal doses of aesthetic taste and logical clarity. Our theories are always as much science fiction as they are science fact.
I agree with Bakker than cognition of the real just isn’t possible. But we must distinguish between cognition on the one hand, and sensation, feeling, and intuition on the other. If an intuition of the real is our goal, using the reflective instrument is like shining a flashlight in search of darkness. Reflective cognition is like King Midas, turning everything it touches into noetic gold. It transforms everything not-I into food for itself, digesting the world and defecating whatever it can’t assimilate as waste. It does’t seem to me much of a stretch to say that modernity’s exclusive reliance on reflective cognition is one of the main factors leading to the ecological crisis.
Let me be clear that, while I defend transcendental phenomenology from Bakker’s eliminativist meta-critique, my own philosophical home base is process-relational ontologyI have major issues with transcendental phenomenology as a philosophical resting place. It remains too anthropocentric, too concerned with issues of human access and not attentive enough to solar nucleosynthesis, cellular mitosis, and atmospheric levels of CH4. But still, I just don’t understand how, having grasped the power of transcendental critique–as critique–one could fail to see eliminativist arguments like BBT as anything but dogmatic materialism (materialism has today become the new School Philosophy, though it pretends to be the ultimate critic of all metaphysics). Where I leave transcendentalism behind is in my pursuit of a constructive, cosmologically-rooted philosophy, something the phenomenological approach just cannot provide.

It is clear Bakker has done his philosophical homework. I don’t think it is fair of him to lump everyone into the same transcendentalist clown car, though. Phenomenology was born out of the intense debates between Fichte, Schelling, and Hegel, all of whom accused Kant of not having cleared his vision of dogmatist residues. They all recognized the possibility and the fact of neglect, and even of the neglect of neglect. But for these post-Kantians (with the possible exception of Hegel), the transcendental project was an infinite one by definition, meaning there would never be a point when the a priori structures were finally reached and could be clearly and distinctly spelled out once and for all. Fichte grounded the transcendental historically in the ethical development of humankind, describing philosophy as an attempt to asymptotically approach absolute metacognition as an ideal while never in fact being able to reach it. Schelling went further and grounded the transcendental in the creative developmental arc of the cosmos itself. For Schelling (and here he converges with Whitehead), not even God knows the a priori conditions of experiential reality: the divine is just as caught in the chaotic turmoil of historical becoming as any creature is. None of these thinkers, with the possible exception of Fichte when he is sloppy, thought that impersonal natural systems could be cognized in terms of their own 1st person experience.
Here is Schelling mulling over this exact problem, for ex.:
I could conceive of that being perhaps as something that, initially blind, struggles through every level of becoming toward consciousness, and humanity would then arise precisely at that moment, at that point in which the previously blind nature would reach self-consciousness. But this cannot be, since our self-consciousness is not at all the consciousness of that nature that permeates everything: it is just *our* consciousness and hardly encompasses within itself a science of becoming applicable to all things. This universal becoming remains just as foreign and opaque to us as if it had never had a bearing on us at all. Therefore, if this becoming has achieved any kind of purpose it is achieved only through humanity, but not for humanity; for the consciousness of humanity does not = equal the consciousness of nature” (The Grounding of Positive Philosophy, 1841).
In other words, 1st person reflective ego consciousness is largely a sham. It can tell us little if anything about the unconscious natural ground from which it emerges. Of course, Schelling (like Whitehead) argued that the field of experience extends beyond mere 1st person ego consciousness. My argument with Bakker has always been: why reduce the experiential field that is open to us to 1st person ego consciousness? Most of our daily and nightly experience is not egoic! Most of the time we are flowing through other experiential states more akin to animals, plants, and even minerals. So in a sense mine is also a post-human manifesto. We have never been human, if you want.

Alfred Jarry and Asger Jorn: The Epicurean Influence as Social “Swerve”

As the current conditions in global markets are in a potentially unstable situation the activation of Epicurus’ (341-270 BC) swerve (“Clinamen”) proves to be of some interest, since it introduces us into a mobile and liberating perception of things that corresponds to the risks of the financial hyper-capitalist structure. Epicurus’ positions are firmly opposed to Platonic cosmogony, given that in Plato’s only text on nature, Timaeus, real nature is a perfectly organized structure consisting of geometrical elements, such as spheres, pyramids, cubes, etc. In many ways, quantum mechanics, which describes the behavior of matter on molecular and atomic level, can be interpreted as a continuation of the atomic theory expounded by the philosophers of Atomism (Democritus, Leucippus), of which a late proponent, during the Hellenistic period, was Epicurus himself. The philosopher from Samos tried to relate physics and cosmogony with human nature. We would have to wait many centuries until modern physics confirmed the ancient materialists’ speculation on the atomic composition of matter.
Modern physics explains matter recognizing that atoms move in unpredictable directions. Epicurus idea of continually moving atoms that swerve (clinamen), following the inclination of a fundamental randomness, is already confirmed by the history of the discipline of quantum physics.

More Precious than Gold


Limited to just 12 copies, numbered 1958–1969, the Lunar Rock Edition of Norman Mailer’s MoonFire is designed by Marc Newson. His concept was inspired by the Apollo 11 LEM (Lunar Excursion Module). Each book is contained in a case made from a single piece of aluminum—its surface an actual 3-D topography of the Moon—and comes with a unique piece of lunar rock.

Meteorites from the Moon are exceptionally rare. There are fewer than 70 lunar meteorites known with a total combined weight of approximately 55 kilograms, making them millions of times rarer than gem grade diamonds. However, most lunar meteorites reside in museum collections and research institutions, leaving only 15 kilograms or so available to individual collectors worldwide. Since acquiring an Apollo moon rock is virtually impossible, the only realistic way to own a piece of the moon is by acquiring a lunar meteorite.

Nerval's Lobster



“Why should a lobster be any more ridiculous than a dog? Or a cat, or a gazelle, or a lion, or any other animal that one chooses to take for a walk? I have a liking for lobsters. They are peaceful, serious creatures. They know the secrets of the sea, they don't bark, and they don't gobble up your monadic privacy like dogs do. And Goethe had an aversion to dogs, and he wasn't mad!"
— Gérard de Nerval, when asked why he kept a lobster as a pet and walked it on a leash.
