Mars Needs Insects

Sarah Scoles in The New York Times:

At first it was just one flower, but Emmanuel Mendoza, an undergraduate student at Texas A&M University, had worked hard to help it bloom. When this five-petaled thing burst forth from his English pea plant collection in late October, and then more flowers and even pea pods followed, he could also see, a little better, the future it might foretell on another world millions of miles from Earth. These weren’t just any pea plants. Some were grown in soil meant to mimic Mars’s inhospitable regolith, the mixture of grainy, eroded rocks and minerals that covers the planet’s surface. To that simulated regolith, Mr. Mendoza had added fertilizer called frass — the waste left after black soldier fly larvae are finished eating and digesting. Essentially, bug manure.

The goal for Mr. Mendoza and his collaborators was to investigate whether frass and the bugs that created it might someday help astronauts grow food and manage waste on Mars. Black soldier fly larvae could consume astronauts’ organic waste and process it into frass, which could be used as fertilizer to coax plants out of alien soil. Humans could eat the plants, and even food made from the larvae, producing more waste for the cycle to continue. While that might not ultimately be the way astronauts grow food on Mars, they will have to grow food. “We can’t take everything with us,” said Lisa Carnell, director for NASA’s Biological and Physical Sciences Division.

Tuesday Poem

Migrants

Strong boys to work on the farm.

The sad lot of migrants in the shadows.
The emaciated look of Mother Africa.
The uncertainties of the desert girls.

Look:
………….. Far away Aquarius has lost its flag.
………….. Multifaceted Africa lies down once again.
………….. Storm and night mingle in my heart,
………….. The flowing blood no longer human blood.

Look:
………….. In the distance, floodlit in the desert of Libya,
………….. The slave market of my fellow Blacks.
………….. At the heart of night men
………….. An outrage to humanity. This brother who is not me.

Strong boys to work on the farm.

In the murky apocalyptic night of the desert
The migrant hungers for virtue, dignity, justice.
In the meshes of emboldened and fierce smugglers
The solitary migrant dies
King of stone
Grain of sand in the auction sale.

On Yasmine El Rashidi’s “Laughter in the Dark” and Egyptian Festival Rap

Peter Holslin in the Los Angeles Review of Books:

Mahraganat (which means “festivals” in Arabic) is made primarily by self-taught young men from lower-class backgrounds, whose songs are considered brash, even vulgar, because they rap and sing openly about their lives with seldom a trace of modesty. Egypt’s canonical singers and composers from the 20th century, particularly Umm Kulthum, Abdel Halim Hafez, and Mohammed Abdel Wahab, possessed a virtuosic command of improvisational technique and classical repertoire. By comparison, mahraganat artists appeal first and foremost to friends from the block, weaving a unique lexicon of Arabic slang, boasts, insults, drug references, and sexual innuendo. The artists use Auto-Tune not only to add distortive, festive color to their rugged street anthems, but also for its manufacturer-intended purpose: to keep their voices in tune.

In the Gut’s ‘Second Brain,’ Key Agents of Health Emerge

Yasemin Saplakoglu in Quanta:

Breaking down food requires coordination across dozens of cell types and many tissues — from muscle cells and immune cells to blood and lymphatic vessels. Heading this effort is the gut’s very own network of nerve cells, known as the enteric nervous system, which weaves through the intestinal walls from the esophagus down to the rectum. This network can function nearly independently from the brain; indeed, its complexity has earned it the nickname “the second brain.” And just like the brain, it’s made up of two kinds of nervous system cells: neurons and glia.

Is OpenAI approaching AGI?

Tomas Pueyo, quoting Nathan Labenz in Uncharted Territories:

Nathan Labenz

I determined that GPT-4 was approaching human expert performance. Critically, it was also *totally amoral*. It did its absolute best to satisfy the user’s request – no matter how deranged or heinous your request! One time, when I role-played as an anti-AI radical who wanted to slow AI progress… GPT-4-early suggested the targeted assassination of leaders in the field of AI – by name, with reasons for each.

Today, most people have only used more “harmless” models, trained to refuse certain requests. This is good, but I wish more people had experienced “purely helpful” AI – it makes viscerally clear that alignment / safety / control do not happen by default.

The Red Team project that I participated in did not suggest that they were on-track to achieve the level of control needed. Without safety advances, the next generation of models might very well be too dangerous to release.

Theories of What Makes You, You

by Tim Sommers

One time, this guy handed me a picture of him and said, ‘Here’s a picture of me when I was younger.’ Every picture is of you when you were younger.Mitch Hedberg

There’s synchronic identity, what makes you, you at a particular moment in time – say, now. And there’s diachronic identity, what makes you, you over time. For example, why are you now the same person as when you were twenty-five years old or five (if you are)? These two perspectives – synchronic and diachronic – are deeply interdependent, of course, but philosophers tend to focus on diachronic identity since what is essential to you being you is, presumably, whatever it takes for you to continue to exist. Here are some theories.

You are your soul.

The trouble with this theory is not that it usually has a religious basis. That might be trouble later, but initially the trouble is that it is not very helpful. I am my soul. So, what’s my soul? Is the soul some mysterious, ghostly thing or a Platonic form or is it just whatever is essential to who I am? If the answer is that the soul is whatever is essential to who I am, this seems like just a restatement of the question.

Keep in mind, the great innovation of Christianity was not the soul, an idea that’s been around at least since Plato and Aristotle (who thought we had three souls). The Christian innovation was bodily resurrection.

You are your ego.

The ego may just be the secular soul. Descartes’ version of the ego theory, the most influential, is that a person is a persisting, purely mental, thing. But like the soul it’s hard to unpack the ego in an informative way. It is whatever unifies our consciousness. We survive as the continued existence of a particular subject of experiences, and that explains the unity of a person’s life, i.e., the fact that all the experiences in this life are had by the same person. This is circular, of course. Further, on this view, what happens if I fall into a dreamless sleep? Or get hit on the head and black out? Go in and out of a coma? Am fully anesthetized? When I wake up and start having experiences again, how do I know I am the same ego? How do I know that the ego is a persistent thing at all? Later, we will see what Hume has to say about this.

In the meantime, we are going to need a better theory of the ego or soul before either is going to be useful as a theory of personal identity. Read more »

What are the odds?

by Jonathan Kujawa

In 2016, here and here at 3QD, we talked about some of the inherent paradoxes in democratic voting [1]. We discussed Arrow’s Impossibility Theorem, along with related results like the Gibbard-Satterthwaite Theorem. They tell us that there is no way to convert the individual preferences of the voters into a single group preference that doesn’t also conflict with some simple, commonsense guidelines that we can all agree are reasonable. Things like “No dictators.” And “If everyone prefers Candidate X to Candidate Y, then Candidate Y never beats Candidate X.”

Certainly, voters are sometimes irrationally motivated. I know of an otherwise reasonable mathematician who asked a colleague to vote on their behalf in a departmental chair election. Above all else, this mathematician did not want Faculty Member Z to be elected department chair. They gave their colleague two lists of all the eligible faculty in the department; each list was in a very carefully chosen order. The first list was ordered by the mathematician’s actual preference for who should be elected chair. This list was to be used only if Faculty Member Z wasn’t on the ballot. The second list was ordered according to the mathematician’s best 4D chess assessment of who was most likely to beat Faculty Member Z in a head-to-head election. That list would be used if Faculty Member Z was on the ballot. In the ideal election system, there should be no need for the second list. But strategic voting is very much a thing in elections.

You might assume such paradoxes are due to the vagaries of humanity. From what I can tell, most human minds are filled with a circus of chaos monkeys that are impossible to predict. Imagine describing the here and now to a 2016 version of yourself. Read more »

The case for American scientific patriotism

by Ashutosh Jogalekar

Hans Bethe receiving the Enrico Fermi Award – the country’s highest award in the field of nuclear science – from President John F. Kennedy in 1961. His daughter, Monica, is standing at the back. To his right is Glenn Seaborg, Chairman of the Atomic Energy Commission.

John von Neumann emigrated from Hungary in 1933 and settled in Princeton, NJ. During World War 2, he contributed a key idea to the design of the plutonium bomb at Los Alamos. After the war he became a highly sought-after government consultant and did important work kickstarting the United States’s ICBM program. He was known for his raucous parties and love of children’s toys.

Enrico Fermi emigrated from Italy in 1938 and settled first in New York and then in Chicago, IL. At Chicago he built the world’s first nuclear reactor. He then worked at Los Alamos where there was an entire division devoted to him. After the war Fermi worked on the hydrogen bomb and trained talented students at the University of Chicago, many of whom went on to become scientific leaders. After coming to America, in order to improve his understanding of colloquial American English, he read Li’l Abner comics.

Hans Bethe emigrated from Germany in 1935 and settled in Ithaca, NY, becoming a professor at Cornell University. He worked out the series of nuclear reactions that power the sun, work for which he received the Nobel Prize in 1967. During the war Bethe was the head of the theoretical physics division of the Manhattan Project. He spent the rest of his long life working extensively on arms control, advising presidents to make the best use of the nuclear genie he and his colleagues had unleashed, and advocating peaceful uses of nuclear energy. He was known for his hearty appetite and passion for stamp collecting.

Victor Weisskopf, born in Austria, emigrated from Germany in 1937 and settled in Rochester, NY. After working on the Manhattan Project, he became a professor at MIT and the first director-general of CERN, the European particle physics laboratory that discovered many new fundamental particles including the Higgs boson. He was also active in arms control. A gentle humanist, he would entertain colleagues through his rendition of Beethoven sonatas on the piano.

Von Neumann, Fermi, Bethe and Weisskopf were all American patriots. Read more »

Gerrymander Unbound

by Jerry Cayford

Avi Lev, CC BY-SA 4.0, via Wikimedia Commons

A friend of mine covers his Facebook tracks. He follows groups from across the political spectrum so that no one can pigeonhole him. He has friends and former colleagues who, he figures, will be among the armed groups going door to door purging enemies, if our society breaks into civil anarchy. He hides his tracks so no one will know he is the enemy.

That trick might work for the humans, but artificial intelligences (AI) will laugh at such puny human deceptions (if artificial intelligence can laugh). When AI knows every click you make, every page you visit, when you scroll fast or slow or pause, everything you buy, everything you read, everyone you call, and data and patterns on millions like you, well, it will certainly know whom you are likely to vote for, the probability that you will vote at all, and even the degree of certainty of its predictions.

All of that means that AI will soon be every gerrymanderer’s dream.

AI will know not just the party registrations in a precinct but how every individual in a proposed district will (probably) vote. This will allow a level of precision gerrymandering never seen before. There is only one glitch, one defect: with people living all jumbled up together, any map, no matter how complex and salamander-looking, will include some unwanted voters and miss some wanted ones. To get the most lopsided election result possible from a given group of voters—the maximally efficient, maximally unfair outcome—the gerrymanderer has to escape the inconvenience of people’s housing choices. And since relocating voters is not feasible, the solution is to free districts of the tyranny of voter location. The truly perfect gerrymander that AI is capable of producing would need to be a list, instead of a map: a list of exactly which voters the gerrymanderer wants in each district. But that isn’t possible. Is it? Read more »

What Art Can Do

by Christopher Horner

Grasmere (Photo by author)

Why do we value art? I am going to suggest that a large part of the answer is to do with its unique power to disclose and convey areas of our lives unavailable to us though other means. Art, on this account, is a kind of communication, and kind of act: something performative – a communication that makes something happen, in a way that eludes ordinary discourse. 

By ‘ordinary’ here I mean the kind of communication delivered by language when it is used to convey concepts: ranging from the most banal everyday speech to the most rarefied theory. Of course, ordinary speech acts themselves have a performative quality too – we don’t just communicate information through language, but make things happen, make requests, (‘shut the door’, ‘the meeting is over’ ‘help me!’). Moreover we use our bodies, tone of voice, emphasis and more: and the conceptual content may not even be what matters, especially when something isn’t banal, but matters greatly: moments of grief or joy, for instance. A gesture, a tear, or just silence may be more eloquent than words. It is this ‘beyond’ in our imperfect communications, that hint at what art can do. Art aspires to a more perfect communication: one that takes us beyond the confines of the lonely self.  Read more »

Relentlessness

by O. Del Fabbro

If a city could be an organism, then Kherson in Eastern Ukraine would be a sick body. For eight months, between March and November 2022, Kherson was occupied by Russian forces. Kidnapping, torture, and murder – in terms of violence and cruelty, Kherson’s citizens have seen it all. Today, even though liberated, the port city on the Dnieper River and the Black Sea is still being regularly bombarded: a children’s hospital, a bus stop, a supermarket. Even though freed, how could this city ever heal?

One of Kherson’s citizens is Andryi. As soon as the Russians left, Andryi and his friends started with humanitarian work. For months the former car mechanic had no job. He rather helped others. When the pastor of his church found out about Andryi’s skills to repair roofs, he gave him some money and assignments. “My friend and I started with a house in which an old grandmother and her son lived.” Before Andryi and his friend started their work, three different groups looked at the roof but did not dare to repair it, because the Russians were only four hundred meters away, on the other side of the Dnieper River, waiting to kill humanitarian aid workers. “We decided to do it, and we did it. Praise the Lord, nothing happened.” Three days later, the roof was finished.

While repairing roofs Andryi has been exposed, both indirectly or directly, to a variety of weaponry: mortars, snipers, rockets, you name it. “When we repaired roofs, artillery fire was constantly active. Once, we saw phosphorous bombs in the near distance, then we hid in the basement.” The last roof was the scariest experience. Some of the material that Andryi and his partner use is a plain white awning, easily detectable by the Russians. Being only one kilometer away, the Russians bombarded Andryi and his friend with mortars, but luckily, they missed. “That was scary, but they did a bad job in trying to hit us.” In total, Andryi counted twenty-six explosions. “It was frequent, loud, and very close.” When talking about his war experience, Andryi has, as many Ukrainians, a dry and succinct way of expressing himself. “You realize that you can get hit, when you hear the bomb exploding.”

Friends, family, donations via social media, the pastor, and the members of his church helped to buy materials such as nails, wood and so on, but at some point, Andryi and his friend ran out of money. He then simply helped the military by using his skills as a car mechanic. He built a heavy machine gun on the back of an old Rada, or repaired the sewage system of a village in the countryside near Kherson. Read more »

Exile + the Full Moon

by Ethan Seavey 

Exile is on my mind and there’s a large full moon above my head I cannot see through the clouds. 

I am part of a family of three exiles who are doing it again, recovering after exile, and working hard to stay together. Our shared communities have dropped us for the third time and it feels like I finally recognize the pattern we’ve always fallen into :

1) Find a community that embraces us because it excludes others; and 2) get rejected when we grow to learn that we have become the others.

When I came out as gay in 2015 my family stopped going to Church, specifically the one where we had been attending weekly (with few exceptions) for somewhere around a decade.

It was a personal decision for each one of us. It was an effort to support me. It was also a social decision. While this Church was more progressive than others, it was still a Catholic Church. It seemed to me that priests were required to spend a Sunday sermon every year talking about how being gay is a sin; sometimes hiding it behind the idea that being gay was not a sin so long as you never acted on it.

Many people within that Church remained close friends. They’d ask why we’d stopped attending and I was the reason. It didn’t distance most of our friends, but I remember my younger sibling was forbidden from spending time with one of their friends outside of the friend’s home, because the friend’s mom saw me as a bad influence.

What is it like to be a crab?

Kristin Andrews in Aeon:

Twenty-five years ago, the burgeoning science of consciousness studies was rife with promise. With cutting-edge neuroimaging tools leading to new research programmes, the neuroscientist Christof Koch was so optimistic, he bet a case of wine that we’d uncover its secrets by now. The philosopher David Chalmers had serious doubts, because consciousness research is, to put it mildly, difficult. Even what Chalmers called the easy problem of consciousness is hard, and that’s what the bet was about – whether we would uncover the neural structures involved in conscious experience. So, he took the bet.

This summer, with much fanfare and media attention, Koch handed Chalmers a case of wine in front of an audience of 800 scholars. The science journal Nature kept score: philosopher 1, neuroscientist 0. What went wrong?

Sean Carroll on a feature of nature that is frequently misunderstood: quanta

Sean Carroll at Preposterous Universe:

The basic issue is that people hear the phrase “quantum mechanics,” or even take a course in it, and come away with the impression that reality is somehow pixelized — made up of smallest possible units — rather than being ultimately smooth and continuous. That’s not right! Quantum theory, as far as it is currently understood, is all about smoothness. The lumpiness of “quanta” is just apparent, although it’s a very important appearance.

What’s actually happening is a combination of (1) fundamentally smooth functions, (2) differential equations, (3) boundary conditions, and (4) what we care about.

This might sound confusing, so let’s fix ideas by looking at a ubiquitous example: the simple harmonic oscillator.

the Age-Old Tension Between Doing Good and Making Money

S. Mitra Kalita in Time Magazine:

On Monday of last week, I joined women from around the world at the Reykjavík Global Forum in Iceland, to talk democracy, technology, and artificial intelligence, among other topics. Four days later, Sam Altman was suddenly fired from his role as CEO of OpenAI, and I religiously followed the twists and turnsbravado, and infighting that unfolded over the weekend. The bookends of the week form a bit of a metanarrative around how to save or support innovation that creates massive societal upheaval. After Altman’s dismissal from the nonprofit behind ChatGPT, we are left pondering who should be in charge of these new technologies that spare no industry or institution.

OpenAI’s six-member board fired Altman, vaguely alluding to lies in his communications with them. The organization operates as a partnership between its nonprofit and for-profit arms, whereby the latter raised money from investors and promised that profits above a certain level would be donated to the former. As The Atlantic explained: “The company’s charter bluntly states that OpenAI’s ‘primary fiduciary duty is to humanity,’ not to investors or even employees.”
