Why our thoughts and actions are essential to any model of the universe

Jenann Ismael at the IAI:

Any attempt to describe the universe as a totality inevitably involves self-reference. This isn’t something that one often confronts in physics. Most day-to-day physics is modelling other systems: cells, gases, planets. We maintain a separation of subject and object, or of investigator and system being investigated. And even though cosmology is explicitly devoted to the study of the universe as a whole, it is customary in cosmology to maintain the imaginative fiction that we – the people modelling the universe – are looking at it from the outside. We adopt, that is to say, the God’s Eye View.

Ultimately, though, we are part of the universe. And that means that however we regiment the universe, whatever regime we work in, if we aim for a theory that describes all of existence, self-reference is unavoidable. Any system that is modelling the universe as a whole – aiming for full coverage of all of existence – is going to encounter self-reference. This is something that we can ignore in some contexts. It matters in others.

The people that have unavoidably encountered it are people who are trying to program an artificial general intelligence (an AGI).

Science needs conformity — but not the kind it has right now

M. Anthony Mills in The New Atlantis:

What is worrisome about the lab-leak controversy therefore is not only that our public discussions and political decisions about Covid-19 may have been hampered by the experts’ mischaracterization of scientific knowledge. The long-term danger is that the experts themselves have helped to undermine public trust in scientific expertise and the institutions that depend on it, at a moment when such knowledge is more deeply intertwined with our social and political life than ever before.

To help us understand what went wrong, we need to ask again what “scientific consensus” really means, and how the experts got it so wrong in discussing Covid’s origins. One tempting response, particularly to those already primed to distrust elites, is to conclude that scientific consensus is inherently dangerous — little more than self-deluded group think, or a tool for manipulating the public. But that is the wrong conclusion to draw. Consensus, rightly understood, is a distinguishing feature of modern science, indispensable to its progress, and part of its well-earned authority in understanding the natural world — it deserves a defense.

Céline Sciamma: Mother Of Invention

at Sight and Sound:

Petite maman seems an unlikely project for Sciamma, who has tended to be very much a realist director. Yet the film is absolutely of a piece with her previous depictions of female experience at different ages – whether depicting the shifting identities and burgeoning desires of teenagers in her debut Water Lilies (2007) and her breakthrough film Girlhood (2014) or investigating nonconformist gender identity at an earlier age, in her altogether ahead-of-its-time Tomboy (2011). It was 2019’s ambitious Portrait of a Lady on Fire – a lesbian romance set in the 18th century – that confirmed her international auteur renown and that also made her a prominent figurehead in contemporary women’s cinema (even a name emblazoned on T-shirts). But Portrait also marked a shift from conventional realism into a stripped back, imaginative realm of poetic filmmaking, an investigation she pursues further in the concise (72-minute), sparely crafted Petite maman.

Sophie Calle and the Art of Leaving a Trace

Lili Owen Rowlands at The New Yorker:

Although there is something oblique about these conceits, Calle is associated, above all, with acts of bald exposure. Her celebrity, which now extends far beyond France, has long been attached to charges of voyeurisme and exhibitionnisme (which have sometimes resulted in legal trouble). Yet, as “The Hotel” vividly shows, what Calle is really looking for is more enigmatic and compelling than other people’s dirty laundry. Rather than erase the residue of human presence, as a “real” maid is expected to, Calle does the opposite, preserving every stain and scrap as a sign or symbol. But of what? This is the question at the heart of Calle’s work, and the answer may hardly be the point; what interests her most is the seduction and projection involved in knowing another person—how fantasy intervenes in every attempt to see and be seen.

Friday Poem

The Toolmaker Unemployed

—Connecticut River Valley, 1992

The toolmaker
is sixty years old
unemployed
since the letter
from his boss
at the machine shop.

He carries
a cooler of soda
everywhere,
so as not to carry
a flask of whiskey.

During the hours
of his shift,
he is building a barn
with borrowed lumber
or hacking at trees
in the yard.

The family watches
and listens to talk
of a bullet
in the forehead,
maybe for himself,
maybe for the man
holding the second mortgage.

Sometimes
he stares down
into his wallet.

The moon has carbon dioxide “traps” that astronauts could use to make fuel and grow plants

Nicole Karlis in Salon:

Though the moon was long considered a barren, inhospitable rocky world, researchers over the past few decades have found that the moon has many of the amenities that humans would need to build a self-sufficient habitat. Indeed, recent discoveries of plentiful water ice pockets on the moon tantalized scientists and space agencies. Now, a new finding suggests that there is plentiful carbon dioxide on the moon as well.

According to new research published in the AGU journal Geophysical Research Letter, scientists have confirmed the existence of lunar carbon dioxide “cold traps,” a geological anomaly in which carbon dioxide could collect for long periods and settle. This discovery will likely have a significant impact on future space exploration as humans — or robots — could use carbon dioxide or other organic materials in the cold traps as fuel, convert it to oxygen, or use it in lunar greenhouses for growing plants.

In astronomy, a cold trap refers to a pocket on the surface of a solid body in which volatile gases can accrue and remain still for long periods, often millions of years. Because many planets and bodies in the solar system, the moon included, lack a significant atmosphere, any unlit area can remain at frigid temperatures for thousands or even millions of years. In that span, gases like carbon dioxide can accumulate and sometimes freeze in sufficient quantities, hence the term “cold trap.” Carbon dioxide freezes at -109° Fahrenheit or -78° Celsius; the temperature on the Moon in the shade or at night is cooler than that, around -298° F (or -183° C) or even colder in some regions.

Is therapy the best way to make the world happier?

Dylan Matthew in Vox:

When people think of ways to help the world’s poor, a few obvious ideas come to mind: giving them cash; preventing diseases like malaria through the distribution of bed nets and pills; treating HIV/AIDS in areas ravaged by those conditions; and other tactics that take aim at economic privation and infectious diseases. That focus is understandable and necessary — but what if it elides a different way of thinking about easing suffering in the world? What if there was a real opportunity to improve the lives of low-income people by devoting resources toward their mental well-being, too?

new report raises that intriguing prospect. Written by Michael Plant, Joel McGuire, and Barry Grimes of the Happier Lives Institute, a research center that aims to find evidence-based ways to improve happiness worldwide, the study looks at the role therapy can play in improving lives in the developing world.

To date, global health efforts have mostly focused on illnesses of the body: malaria, vitamin deficiency, HIV/AIDS prevention, tuberculosis. Obviously, such diseases can affect the mind, and canonically “mental” illnesses like depression can take a physical toll. But historically, mental well-being has simply never gotten equal billing. Until 2015, the UN’s Sustainable Development Goals didn’t even include benchmarks for mental health, even as they focused heavily on infectious diseases and markers of physical health. Through the increased use of tools like randomized controlled trials, policymakers have gotten better at understanding what really works in raising incomes and treating diseases among the world’s poorest people, and what doesn’t. That’s great, but it also may have led to some complacency — the idea that we already know what works.

Rebecca Solnit: Ten ways to confront the climate crisis without losing hope

Rebecca Solnit in The Guardian:

We will meet climate change with real change, and defeat the fossil-fuel industry in the next nine years.

If we succeed, those who come after will look back on the age of fossil fuel as an age of corruption and poison. The grandchildren of those who are young now will hear horror stories about how people once burned great mountains of poisonous stuff dug up from deep underground that made children sick and birds die and the air filthy and the planet heat up.

We must remake the world, and we can remake it better. The Covid-19 pandemic is proof that if we take a crisis seriously, we can change how we live, almost overnight, dramatically, globally, digging up great piles of money from nowhere, like the $3tn the US initially threw at the pandemic.

The climate summit that just concluded in Glasgow didn’t get us there, though many good and even remarkable things happened.

As the War on Cancer Turns 50, Earlier Diagnoses and Treatments Are Saving Lives

Sari Harrar at AARP:

In dozens of laboratory freezers at Columbia University in New York City, 60,000 cancer specimens await testing that oncologist Azra Raza, M.D., anticipates will find “cancer’s first cell” — the earliest mutated cell that will eventually multiply to become a cancer — and lead to treatments that knock the disease out before it grows. The blood and bone marrow samples come from nearly every one of her patients of 35 years, provided as they moved through cancer treatment.

“We have not won the war on cancer,” says Raza, a professor of medicine and director of the MDS Center at Columbia. “Understanding cancer will take 1,000 years. It is too evolved,” she says. “Instead, we have to find the first cell and eliminate it.”

Raza’s $15 million project, with input from a think tank of researchers from eight major cancer centers, aims to collect 50,000 tissue samples from another group: people who do not have cancer­ — yet. Intensive analysis, she says, can find tiny trouble cells, then examine how genetic changes and everyday exposures lead to cancer.

Probation Profiteering Is the New Debtors’ Prison

Andrew Ross in the Boston Review:

The carceral system has become a vast debt machine. It creates a dizzying array of financial obligations for those unfortunate enough to be caught in its dragnet. The lowest hanging fruits are the traffic fines extracted from motorists who fall foul of a speed trap, carefully laid by officers assigned to do “revenue policing” to help fund law enforcement budgets. Judges are also under pressure from county and municipal managers to pass down ever higher fines and court fees to pay for salaries and other local government operations. For those too poor to pay, penalties and surcharges are added to the debt load every step of the way.

At the other end of the system, formerly incarcerated people typically re-enter society with large debt burdens on their backs, accumulated while serving their sentences. A recent NYU study showed that individuals have to pay more than $3,700 annually just to cover basic needs (food, clothing, phone calls) during a prison stay in New York’s prisons. The numbers are much higher in states where the cost of room and board are directly borne by detainees. Wherever for-profit companies are allowed to operate, these sums are further inflated.

….. “There are 47 percent who are with (the President),
….. who are dependent upon government, who believe that
….. they are victims, who believe that government has a
….. responsibility to care for them, who believe that they
….. are entitled to health care, to food, to housing, to you
….. name it. . . . That’s entitlement.”  —Mitt Romney

….. “All things therefore whatsoever ye would that men should
….. do unto you, even so do ye also unto them.” —Matthew 7:12

Who there knows how good it is to know
a warm bed and a roof? If any, speak.

Who there knows how good it is to know
a schoolroom? If any, speak.

Who there knows how good it is to know
the stiffness of new shoes? If any, speak.

Who there knows how good it is to know
the steam of a meal on your cheeks? If any, speak.

Who there knows how good it is to know
some God hears you weep? If any, speak.

Who there knows how good it is to know?
All of you know, so speak.

Say you know how good it is to know.
All of you know, so speak. Say it’s OK

for others to know how good it is to know.
Go ahead, speak.

If you know how good it is to know,
why then don’t you speak?

Why then don’t you speak?
Say something. Speak. Speak. Speak.

Shark’s Eye: The more I learned about the pain humans can cause each other, the more I turned to sharks

Rebecca Flowers in Guernica:

It was the year that my sister, feeling depressed and isolated, swallowed an entire bottle of pills. For that day, and perhaps a few days afterward, my brain stopped making memories. There are fragments that float to the surface. The doctor telling us she might have ruined her kidneys forever. The image of a scene I hadn’t actually witnessed: the plastic pill bottle falling from my sister’s limp hands and clattering to the tile floor. The blur of an ambulance ride. The clearest memory I have is from a few weeks later: I am doing homework by my sister’s hospital bed, she in her hospital gown, my uniform still on from the school day.

Three years later, my parents split up. In the fallout, my sister went to live with my father. I stayed with my mother, who was heartbroken. I tried to comfort her, but by now all I knew was how to be quiet.

…The more I learned about the world of humans — the pain they can cause each other, the fighting and the guilt — the more I turned to sharks. I caught a Shark Week special depicting the rash of shark attacks in the summer of 1916 that had inspired Jaws. I watched eyewitness videos and documentaries about marine biologists. I grew on a diet of encyclopedias and books filled with Latin names and anatomically correct illustrations of sharks.

Nancy Pope: Smithsonian’s National Postal Museum

Joshua Bauchner and Nancy Pope at Cabinet Magazine:

CABINET: Let’s start with something very basic: When I send a hand-addressed letter from here in New York to a friend in Oakland, how does it get there? Why do letters go places when I put them in the mailbox?

NANCY POPE: Getting the mail from one place to another has four basic segments: acceptance, processing, transportation, and delivery. Acceptance can happen in your mailbox, in one of the on-street blue collection boxes, or at a local post office, and conveys your letter, via the local post office, to the nearest processing center; this still happens mostly by hand. The next two steps are really all a question of automation, as they have been since after the end of World War II. Processing comes down to machinery. Each of the three different types of mail—letters, packages, and flats, which include catalogues and magazines—has its own way through the system, its own machines. Your letter first goes through a culler, which separates the letters from the packages. It then enters a machine that does facing and canceling. The machine finds the stamp thanks to a phosphor in the stamp; it senses the phosphor, flips the envelope face up if necessary, cancels the stamp, and sends the letter on to a barcode machine, which will actually read the address, your handwriting.

In A Post-Hegelian Spirit

Byron Belitsos at Marginalia:

But Dorrien takes a new turn in his monumental reprise of his previous work on the post-Kantian epoch in theology. In a Post-Hegelian Spirit elevates Hegel’s status as the indispensable philosopher, and we even hear Dorrien say that, like himself, “Adorno, throughout his career, and Derrida, in his later career, similarly grasped that we are never done with Hegel.” But Dorrien’s new tome has another broad mission, that of highlighting his “discontent” with the present moment, which is advertised right up front in his subtitle: Philosophical Theology as Idealistic Discontent. But why an idealistic discontent?

Dorrien makes clear in the book’s opening page that he is “making an argument for a liberationist form of religious idealism” while also critiquing post-Hegelian theologians like Karl Barth who may have been “penetrating” thinkers but were “one-sided compared to Hegel.”

I sank into severe depression during the pandemic. Here’s how I emerged

EAD in Science:

The tile floor was cold and hard against my knees, but I couldn’t move from my spot in front of the toilet. It was the third morning that week I had spent violently throwing up because of anxiety at the prospect of going into the lab. So far, I had been able to stay home without consequence. But that day I was scheduled to meet other lab members to work on an experiment essential for my Ph.D. project. At 5:45 a.m. I let them know I wouldn’t be coming in, feeling a wave of guilt. “How did I get here?” I wondered.

I entered grad school in July 2019. The first semester went smoothly—I did well in my classes, met interesting people, and found an adviser after a series of lab rotations. But everything changed during my second semester, as COVID-19 spread. With our lab shut down and bench work impossible, I tried to focus on my classes, which had gone virtual. Eventually, though, I experienced Zoom burnout and began to pay less attention. As in-person interactions waned, so did my mental health. When the semester finished, I moved to doing research full time, and my days had even less structure and social connection. My university lifted restrictions on lab work in July 2020, but I couldn’t find the will to go in. The only person I saw for the next few months was my husband. Friends and family reached out, but as I sank deeper into depression, I stopped responding.

Throughout my life I had dealt with more minor mental health issues, but what I experienced during the pandemic was unlike anything before. My depression was so bad I was essentially bed-bound. I barely managed to shower once a week, could not sleep, and had zero motivation to work—a problem I never imagined I would have. Yet there I was, doing nothing day after day. The inertia was insurmountable.

I noticed that many of my peers were publishing papers and winning awards. I felt certain I didn’t belong in my program and would be asked to leave as soon as my lack of progress was brought to light. I canceled meetings with my adviser for 2 months straight, hoping she wouldn’t notice.

Wittgenstein’s “Tractatus” at 100

Jared Marcel Pollen in the Los Angeles Review of Books:

It surprises us to learn how much literature was penned in the trenches of World War I. The poems of Wilfred Owen or the early tales of Tolkien, for example, are all the more exceptional when we consider that they were composed amid states of mortal terror. But the most incredible and most stupefying example perhaps is Ludwig Wittgenstein’s Tractatus Logico-Philosophicus. Less than a hundred pages long, it is a slender book that, according to its author, set about to find a “final solution” to the problems of philosophy (a phrase made even more cryptic by the knowledge that Wittgenstein and Hitler were once schoolmates). And indeed, when the Tractatus was published in the fall of 1921, Wittgenstein effectively “retired” from his trade, believing that he’d found the basement of Western philosophy and had turned off the lights when he left.

The Tractatus began as a series of notes that Wittgenstein kept in his bag throughout his tours with the Austrian army.
