Klaatu barada nikto: Robert Wright’s “The God Test”

by William Benzon

Into The God Test, by ChatGPT

The God Test: Artificial Intelligence and Our Coming Cosmic Reckoning (2026) is Robert Wright’s sixth book. It builds on themes and concerns in the previous five books, which I’ll get to at the end. As the title indicates The God Test is about artificial intelligence.

Until OpenAI released ChatGPT in late 2022 AI existed mostly in science fiction, a collection of genres that has become increasingly popular in the last five decades. The intellectual discipline was relatively small, problematic, and often institutionally precarious. Moreover those within the discipline were sometimes/often motivated as much by cultural mythology as by the challenges presented by the discipline itself. Curiosity kept researchers engaged in problem solving while mythology told them why those problems are important.

The particular approach to AI that produced ChatGPT, so-called deep learning, has a characteristic that differentiates it from much earlier work in AI and from all other work in computing: We don’t know how it works. And by “we” I don’t mean only the general public or intellectual specialists outside the discipline. By “we” I mean everyone, including the scientists and engineers who have developed the technology.

The standard line about computers, that they only do what they’re programmed to do, doesn’t apply to large language models (LLMs), the particular technology that dominates the current scene. The engineers program a transformer to “examine” (or, if you prefer, ”consume”) a large corpus of texts, and the transformer constructs (“emits”?) a “model” of the language in those texts – Wright discusses this process in “Chapter Two: The Great Inversion.” The inner mechanisms of that model, however, are opaque. The engineers who programmed and ran the transformer can’t see into it to see how it works – something Wright discusses in “Chapter Four: The Evolution of a Large Language Model.” Read more »

Helen Keller, Mitch McConnell, and the Missing Ring: Meditations on the Absurd

by Joan Marcus, Guest Columnist 

Fifty years ago, my father became convinced that a girl named Lucy in the apartment below ours stole my mother’s engagement ring.

He blamed my brother for this. He thought Bobby had let this child into our flat and she’d entered our parents’ bedroom, opened the top dresser drawer, and nicked the ring from its wooden tray alongside a collection of loose buttons and my father’s cufflinks. He raged at my brother, who was only eight. It’s what he did—yell, mostly at my brother, about things that mostly weren’t his fault. This particular tantrum was bizarre even by my father’s standards. Lucy was a tiny thing with white-blonde hair and scraped knees, in the same third-grade class as my brother, but never his friend. She didn’t come over for playdates. No one had seen her in the apartment, nor did she have any history of showing up uninvited. If my father really thought Lucy took the ring, he could have confronted her mother, but he never did, so he must have known it would make him seem crazy. Even so, he was convinced, and no one tried to dissuade him. Not his wife. Certainly not his frightened children, who knew the best thing to do with an irrational parent is to clam up and wait for him to comes to his senses.

                              *

I’ve never known what to do with disagreement. Whether it’s a friend, colleague, or loved-one, I find myself tongue-tied the second anyone challenges me. Blame it on my father if you must. The less trauma-informed explanation is that I feel responsible for marshalling all my proof and articulating it brilliantly, and in the moment, the best proofs elude me—even, or perhaps especially, when the disagreement is about something absurd. Once I stood at the front of a classroom trying to convince a bunch of college first-years that Helen Keller wasn’t a fraud. The “Keller was faking it” conspiracy theory gained traction in the dark days of COVID lockdown, over TikTok at first, spreading however these things spread. The original posts were likely ironic, but I assure you my students in fall of 2022 were believers.

Because this was a classroom discussion, I wasn’t speechless the way I would be if a family member lobbed a conspiracy theory at me, but I wasn’t exactly confident. “How Helen Keller learned to communicate is well-documented at the Perkins School for the Blind,” I tried. “You can go research it any time.” Read more »

Poem by Jim Culleny

—the family of simple, monosyllabic words.
                   –Adam Zagajewski, Another Beauty

Bread House Salt God

The tsunami smell of yeast inundated our house
the mornings our mother baked bread,
up through floorboards it came, up the stairwell
it spread stirring our dreamselves alive,
fresh loaves, bells for the nose, their toll
expelled sleep from somnolent heads,

Broken bread, “you are the salt of the earth,” he said
as a breeze blew over a wine jug’s spout which made
a lowing sound as if a ghost were playing a bass flute,
as if a shade could play such an instrument.

We heard with superstitious ears
and over our shoulders cast that condiment,
a column of salt. Lot’s wife turned around
with sorrow. Her heart bled, it thumped
to her anger at what God did, ached
over the ashes of each house.
over the ashes of Ash Wednesday,
over the ashes of the day before,
over smoking coals glowing with
godjustice.

She stood unnamed becoming a pillar of
sodium chloride looking back,
watching tongues of fire,
watching pillars of smoke,
watching her world burn,
condemned for not keeping her grief hid.

Carr Crash

by Ken MacVey

Brendan Carr (from Britannica)

You may not have heard of Brendan Carr—he is not exactly famous but with time he is getting better known, and you are likely to hear more about him in the coming months. Officially, he is the chairman of the Federal Communications Commission, which licenses radio and television broadcast stations in the United States. Unofficially, he is becoming President Trump’s policeman on what these stations may convey and not convey about Trump and his administration.

On July 16, Trump  gave his primetime speech on “election security,” which to no one’s surprise turned out to be about alleged election tampering and a push for his SAVE America Act bill to take effect before the November mid-term elections. That bill would overhaul the country’s voter registration system and restrict voting by mail. The bill is stalled in Congress. CBS carried  Trump’s speech but ABC and NBC did not. The next day Trump publicly declared that ABC and NBC affiliate stations should lose their FCC broadcasting licenses  because they did not broadcast his speech.

This is nothing new. Trump several times before has called out for taking away licenses of network affiliate broadcasters because he was upset with their news coverage, or more particularly, coverage of him and his administration. If any licenses are to be revoked or denied it would have to be through the FCC. By legislation the FCC has five commissioners. By statute no more than three commissioners may belong to the same political party. Currently there are three commissioners—two Republicans and one Democrat. Trump appointed Republican Carr as chairman in January 2025, who he also originally appointed to the FCC in 2017 after Carr had served as FCC general counsel.

The Communications Act of 1934–the governing statute for the FCC– provides that licensed broadcasters must serve the public interest as a condition of their license. The rationale for requiring licensing is that the radio and television broadcast spectrum must be geographically limited to a small number of broadcasters to avoid airwave interference with each other. Airwave broadcasting is a “natural oligopoly” in a way similar to how electric and other utilities are what economists and regulators call “natural monopolies.” Such monopolies, for example, are said to be necessary to prevent competing companies placing multiple parallel water pipelines or electric transmission lines in or on the same street when a single pipeline or transmission line would more efficiently serve customers. As natural monopolies, privately owned utilities must serve what is legally called “public convenience and necessity” and are accordingly regulated. Similarly, FCC broadcast  licensees have a public interest requirement and are subject to FCC regulation. Read more »

Will AI Replace Wine Criticism?

by Dwight Furrow

In World of Fine Wine, Master of Wine Benjamin Lewin speculates about whether AI could replace human-generated wine criticism. He acknowledges the obvious limitation: “A chatbot cannot smell or taste.” Yet he thinks this may not matter. Wine, after all, consists of measurable properties. The intensity of color and its wavelength can be specified. Labs can analyze acidity, sugar, alcohol, viscosity, and volatile compounds with far more precision than the human palate. Feed those measurements into an AI trained on the enormous archive of published tasting notes and scores, Lewin argues, and the machine could spit out the patterns linking chemical composition to human judgment about taste. Impressions would be replaced by actual measurement, he suggests. Eventually, what he calls “a self-driving laboratory” (analogous to a self-driving car) might generate tasting notes, predict aging, adopt different critical “personas,” and achieve “greater objectivity than any single human expert.”

Common sense might suggest that the fact that an LLM cannot smell or taste should end the discussion. But that limitation does not harm Lewin’s argument. His point is that an LLM, supplied with laboratory data along with the vast archive of online tasting notes, could accurately predict what informed tasters would find in a wine. An AI that can reliably predict what expert tasters would report would be functionally equivalent to what actual tasters discover.

I do not think we can dismiss this speculation out of hand. Read more »

The Odyssey of Old Age

by Nils Peterson

The Greek poet Cavafy begins his fine poem “Ithaka”:

When you set out for Ithaka
ask that your way be long,
full of adventure, full of instruction.
The Laestrygonians and the Cyclops,
angry Poseidon–do not fear them:
such as these you will never find
as long as your thought is lofty, as long as a rare
emotion touch your spirit and your body.
The Laestrygonians and the Cyclops,
angry Poseidon-you will not meet them
unless you carry them in your soul,
unless your soul raise them up before you.

Here I am, cast up on the shores of 92 years. I have things to weep over, yes, and things to rejoice over, yes. Most of my companions have gone. I find myself wanting to tell my story, and so I do in poems that remember and in bits of memoir. My court is the internet where friends sometime listen and sometimes, sometimes I say, catch the attention of an unknown who’s wandered in looking for wine and a little food and some entertainment.

Well, my “thought” was not always “lofty” so I’ve met Cyclops, “angry” Poseidon, many sirens, maybe even a tribe of Laestrygonians.

And the story is always with me, a continual source of imagery, a way of understanding myself and a help in explaining my self to others. (See the little gift you get from the difference between myself and my self? a readerly gift.) I’ll come back to this.

I was a reading a poem by Derek Walcott whose opening obliquely refers to Homer’s story and I found myself wondering how long it would be before the Homer mentioned in those lines would go unrecognized by everyone except scholars. I fear the loss of the mythologies of Greece and Rome that provided a binding field of imagery and felt-meaning to centuries of poets of the West. Yes, it is part of the general downgrading of the humanities but also an understanding that one can no longer be well-educated and eurocentric. And we are finite. We do not have “world enough and time,” memory enough and time. So much must be lost, replaced, forgotten. But the Odyssey? I need it. Read more »

Mental Stuff

by Christopher Hall

Generated with ChatGPT

Philosophers aren’t under the same obligations as scientists; they may come to a conclusion first and then work backwards through the argument. This may be because the alternative to a given conclusion is undesirable; Derek Parfit, for example, spent his career defending moral realism because, to him, the alternative was a relativism which meant that ethics didn’t really exist at all. There is a danger, of course, in arguing for what we want to be true instead of simply letting the argument take us where it will. But if the argument is ultimately sound, who cares what impulse originated it? I’m mentioning all of this because, as a very amateur philosopher, I’d like to believe that, even if I very much want something to be true, that doesn’t mean I’m always bound to create shaky arguments for why it is true.

So, one thing I’d like to be true is that AI will never achieve anything like human consciousness. Please note that this is not the same as the claim that AI already has achieved consciousness; that’s a claim that I think is pretty readily dismissed. Even if chatbots are by now easily capable of passing the Turning test, that merely demonstrates that we have no reliable method for determining the existence of consciousness anywhere other than through words and actions, which may be well generated without any conscious thought-process behind them. And I’m actually less threatened by the world-imperilling potential of a conscious AI (the world is already plenty imperilled by more imminent dangers) than I am with aesthetic concerns. I can reject all AI writing as slop at this point purely because it’s an exercise in mindless regurgitation. An AI isn’t thinking about the color red when it writes “the red dress,” and it most certainly isn’t thinking about more complex subjective experiences like “the red dress she wore that particular day in late autumn in Toronto.” Without this interiority as a basic reference point, the writings of AI are nothing more than the noodling of a p-zombie.

This position isn’t particularly novel or innovative. The problem, of course, is with that “never” – can I say with absolutely confidence that an AI will never have the interiority – the conscious basis of experience – that it takes to write great works of literary art? It’s at this point that my belief in the inherent limitations of AI clashes with some more basic intuitions about the nature of consciousness itself. Read more »

What Is It Like to Be a Phenomenologist?

by Jim Hanas

Looking back I see that my undergraduate education—as seen through my three (one merely attempted) majors—was a tour through the grammatical persons. I started out majoring in political science (and studying Latin, to my lasting regret), because I thought I wanted to be a lawyer. Third-person plural.

I quickly switched to psychology, which was divided between third-person singular (experimental psychology) and second-person singular (clinical psychology). This alone should have been the clue that psychology might not be a science, but there were others. Outside of the statistics classes—reassuring as they were to the field’s aspirations—all the textbooks had the same plot. Unlike math or chemistry textbooks, which I assume are at least technically progressive, psychology textbooks were a tour of incommensurate, historically explored possibilities, with chapters on psychodynamic theory, Gestalt, behaviorism, and—finally—the then-nascent field of neuroscience. The apotheosis of the field’s haplessness appeared in each textbook with the appearance of the “diathesis–stress model” of schizophrenia, which proposed that psychopathology arose from a combination of genetic predisposition and environmental factors. No kidding.

This sent me across campus to the philosophy department, where I discovered phenomenology, which—at its most rigorous—is the systematic investigation and description of first-person singular experience. “Lived experience” has become a cri de cœur in recent years, in which I hear the echoes of Husserlian Erlebnis or Sartre’s l’expérience vécue, though—as with many things—current usage is a memed-down version meant to evince uninterrogable private experience. But, or so phenomenology claims, there is a lot that can be said and communicated  about the structure of these private experiences. For example, the idea of an object and the object itself, while sharing the same content, have different phenomenological properties. One appears in time and space, is experienced as having permanence, etc., while the other does not. Almost any first-person experience—from the experience of mathematical proofs to elusive states like ennui—can be the subject of such investigations.

I graduated with a double major in psychology and philosophy and—in the four decades since—it does not appear that much progress has been made in reconciling the third-person view with the first-person view. Psychology with philosophy. Read more »

When Was The Last Time You Took A Road Trip?

by Eric Schenck

Road trips were a staple of my childhood.

My family didn’t have money, so a vacation was usually just driving somewhere else. And as long and soul-sucking as some of these drives could be (three days from California to Texas was a favorite), they were great. 

Homemade sandwiches. Stacks of Nickelodeon magazines. Picking a car color, and then seeing how many of them you passed. What more could a 12-year-old want?

But at some point, all of this stopped. 

Life got in the way. I grew up, went to college, moved abroad. I used my time more productively, and the entire idea of a road trip started to take on a campy feel of something very much not necessary.

Who would drive somewhere…just to drive somewhere?

But that’s what I did in July. 

For the first time in years, I found myself on a road trip. And it was great. I flew into Los Angeles, and for the next five days, my surfing bud Martin and I lazily made our way to San Francisco.  Read more »

Who Is ‘Authentically’ Working Class?

by Robert Jensen

Most politicians pledge to work for the working class, or sometimes for working families, a less Marxist-sounding label. Meanwhile, scholars struggle to define the category. I won’t assess the political posturing or adjudicate definitional disputes, but my work experience—spanning six decades and a wide variety of jobs—illustrates why the claims of working-class authenticity that are prized in today’s politics are so fraught.

Once upon a time, the working class was understood as people in capitalist economies who don’t own the means of production and must sell their labor to owners. But as economies grew more complex, anomalies piled up. What about managers who aren’t owners but make lots of money doing the bidding of owners? What about technical employees whose specialized skills give them bargaining power? What about small-business owners of modest means who hire employees? Turns out there are lots of “contradictory class locations.”

I’ve never been a manager, had any specialized technical skills, owned a business, or made big money, but my class status is rife with contradictions and conundrums.

Work history

My paternal grandfather, an immigrant from Denmark, was a blacksmith in a small town in North Dakota, but my father had no interest in the family trade. After a lackluster college career on the GI Bill, he got a job as an insurance adjuster—a white-collar working-class job for which he wore a shirt and tie to the office but got paid like a laborer. My mother, whose family had a similar trajectory, stayed at home with four kids until we were all in school and then took a series of low-paid office jobs.

Although I didn’t’ realize it at the time, money was tight in our family. I didn’t get shiny new things, and family vacations were low-budget affairs that involved staying with relatives or in a borrowed camper. We always had a house and ate regularly, and I didn’t feel poor, but I knew the difference between myself and the affluent kids at school. Read more »

Once Upon a Hallucination: Review of “Psychonauts: Drugs and the Making of the Modern Mind”

by Marianne Janack

Synaesthesia is one of those phenomena that make the scientific study of perception difficult.  Its general characteristic is that, as one researcher puts it, extraordinary experiences follow from ordinary sensory in-put. Some synaesthetes hear in color; some hear something and it makes them feel like they have been touched (physically) by something or someone; some connect colors to tastes. The phenomenon of “colored hearing” had been studied by German psychologists since the early 19th century, but early psychonauts discovered that these experiences were not necessarily inaccessible to people who weren’t synaesthetes by nature. One could induce those experiences with mind-altering substances.

Psychonauts: Drugs and the Making of the Modern Mind by Mike Jay (Yale University Press, 2023) is an intellectual history of the exploration of the mind that was undertaken by people who took mind-altering substances. Baudelaire, William James, Maud Gunn, Timothy Leary, Sigmund Freud, and Thomas de Quincey all make appearances, as do a cast of less familiar names. In addition to being an intellectual history of self-experiments, though, it is a book about how theories of mind became theories of brain and neurochemistry, and about how self-experiments—and their disappearance—were part of that change. The book has 4 sections: Part I is The New Accelerator: Drugs and Mental Enhancement (the chapters are “The Elixir of Life” and “Prosthetic Gods”); Part II is Beyond the Veil: Drugs and the Limits of Consciousness (the chapters are “A World of Pure Experience”, “The Unseen Region”); Part III is Saturnalia of the Senses: Drugs and the Creative Imagination (the chapters are “Tales of the Hashish Eaters,” and “Extasi, Fantasia, and Illuminati”); Part IV is Lost and Found (the chapters are “A Sin, a Crime, a Vice, or a Disease?” and “Twice Born”). Jay’s history is about how the subjective accounts of drug experiences came to be seen as mere anecdotes rather than evidence, and how moral and political concerns came to dominate the discussion of drugs and mind-altering substances.  Jay argues that the way forward for research into drugs and the mind must go back to older methods which paired laboratory data with data gathered from first person accounts.

Can AI really think like a scientist?

by Ashutosh Jogalekar

AI is collapsing barriers in scientific disciplines, most notably in math. An 87-year old conjecture named the Jacobian conjecture was recently solved with help from AI. An AI model solved another 80-year old conjecture, the distance conjecture. Many Erdős problems, named after the prolific late mathematician Paul Erdős, are swiftly succumbing to AI. Some mathematicians like Terence Tao – regarded by some as the greatest living mathematician – have simply come to terms with using AI in their research and think that AI will be as integral to math as were slide rules and calculators. Nor is math the only field that is is seeing striking inroads made with AI. Other theoretical disciplines, including theoretical computer science, are also being rattled. Theorist Henry Yuen sounded a bit shaken to see how many problems in his discipline were being solved by AI, and said that he could “feel the importance of these problems in his bones.”

Given this spectacular progress of AI in math and science, it does not seem unreasonable to ask the next question: how long before AI solves outstanding problems in all sciences: physics, chemistry, biology, astronomy, geology? And then how long before it also solves outstanding problems in other adjacent disciplines: neuroscience, psychology, anthropology, sociology, philosophy? Will we soon live in a post-human world, at least so far as science is concerned, which considering that science is what helps us make sense of the universe, means a post-human world, period?

First of all, let’s state the obvious. Any kind of optimism that AI will solve problems in applied sciences like chemistry and biology anytime soon is misplaced for obvious reasons: unlike math and theoretical computer science and even parts of theoretical physics, these disciplines need experimental verification and the right data. Unlike math, you simply can’t think your way to a new drug or material. In fact if you look at most of the Nobel-winning discoveries in these disciplines, you will realize that while AI could likely have helped accelerate them by generating ideas, most of them involved the serendipitous discovery of new biological molecules or mechanisms. An equal number involved the invention of new tools and techniques. It’s hard to see how AI could have possibly done this by itself. At least in the near future, I don’t see how AI can simply think its way to a new cancer drug, a new mechanism of memory or a new technique to unravel the mysteries of life, hype from AI leaders notwithstanding.

But beyond these specific domains, the entire debate around AI revolves around a more profound question. Read more »

The Frictionless Years

by Lei Wang

1. The Odyssey

I did not expect to enjoy this recent adaptation of The Odyssey, and indeed I did not. I watched for purposes of cultural touchstoning and schadenfreude, the way I enjoyed survivalist fiction as a child. Thank goodness I, unlike the main character in Hatchet and Brian’s Winter, get to be safe and warm and don’t have to plot to trap a bad-tempered moose just to survive, or use my own urine as a hot water bottle. Over the three hours in the theater, I was extremely grateful not to have to spend time on an undulating boat without sunscreen, kill, or be a man in any era. Which is perhaps not supposed to be the takeaway.

And yet I feel there must be something there to stories that have lasted, stories I don’t quite have the taste or patience for, which just means I don’t have enough understanding. The ex-journalist in me maintains that anything can be interesting; I am still waiting to love baseball, if only someone could explain to me the metaphysical implications. Film adaptations of great literary works often feel unsatisfactory because the parts that make literature great and literary—the interiority and insights—are lost. The odyssey is an internal story being told as an external adventure story, which is nonetheless a great marketing trick more philosophers could use.

When Dr. Athena Potari (yes, her name is actually Athena) explained the internal story of the epic on a recent Zoom meeting for a group of idealist philosophers and taggers-on like yours truly, she deployed so much etymology I felt as if I were listening to conspiracy theories, except coming from a Greek scholar who’s taught at Harvard and Oxford.

Consider the name Odysseus, which Homer himself translated as “he who gives or receives pain,” and which any quick Google search will tell you has been traditionally linked to the Greek verb odussomai—“to be angry at,” “to hate,” “to be grieved,”—in short, to suffer. Read more »

Sometimes There is Nothing Wrong with Letting a Child Drown

by Tim Sommers

Honestly, in academic philosophy a great, or even a good, title is not really necessary. Perhaps, the most influential philosophy article of the twentieth century is called “On Denoting.” Really, Russell? That’s all you got? Compare Donald Davidson’s “A Nice Derangement of Epitaphs.” Now, that’s a title. Unfortunately, given that he argues there is no shared language, it has faded from view a bit. Thomas Nagel’s “What is it Like to be a Bat?” has got to be near the top of any “best of” list, especially considering its influence. But my favorite title, which I have borrowed for this article, is “Sometimes There Is Nothing Wrong with Letting a Child Drown” by Travis Timmerman.

I met Professor Timmerman a couple of years ago, a nice guy with no documented history of drownings, and asked him about it. (You don’t meet George Lucas and not ask him about Star Wars, right?) He told me that when the article is reprinted in textbooks and anthologies, it is consistently retitled “Reply to Singer.” Why?

Well, it is a reply to Singer. But really, I suppose, the point is to deemphasize the whole “children drowning” thing – which is too bad because it’s a real attention grabber. The article to which Timmerman is replying is the one in which Singer introduced a thought experiment, called “The Pond,” second nowadays only to the trolley problem in terms of how well-known it has become.

You are walking to work and pass a shallow pond. A small child has fallen in and is drowning. No one else is around. You could wade in and save her easily, but doing so will ruin your shoes and make you late to give a lecture. Almost everyone agrees, of course, that you must save the child; ruined shoes and a missed (or late) lecture are trivial next to a child’s life.

Singer builds a much larger argument on this shared intuition. If it is wrong to let the child drown to protect your shoes, it is equally wrong to spend money on luxuries like new clothes, restaurant meals, vacations, etc. while children elsewhere die preventable deaths that the same money, spent differently, could have saved them. Distance – spatial, temporal, or relational – he insists, is morally irrelevant. A drowning child ten feet away and a starving child ten thousand miles away place the same demand on us, provided our help would work equally well in both cases. Read more »

$5 Says My Skirt is the Same Thing as Your Coffee Mug

by Carlota Figueroa

Actually, I can bet you another $5 that when you read the title of this article you thought that I was crazy and that there is no universe in which these two things can be the same. After all, you’d probably tell me that one is a stylish piece of clothing and the other is a kitchenware article that holds the magic potion to wake you up in the morning — definitely not the same thing. And you would be right. Well, partially right. But let me ask you just one thing: how do we define the word same? If we use every normal person’s definition of same as “resembling in every relevant respect,” (maybe you’re a normal person and you’d use a different definition, but this is Merriam-Webster’s so I’ll take it as a good point of reference) then yes, you win: a skirt does not resemble a coffee cup in every relevant respect. It’s not even a close call. However, if we use many mathematicians’ definition of same as “homeomorphic to one another”, then I’m sorry to tell you, but you owe me $5.

Our three homeomorphic shapes.

Now, unless you have some background in mathematics or physics, the adjective “homeomorphic” probably sounds rather made up. What does it mean for two spaces to be homeomorphic to one another? It means that there exists a homeomorphism between them. I know, way to go, using the word to define itself. The truth is, in mathematics, a homeomorphism is one of the most important and magical functions there is. In technical terms, a homeomorphism is a bijective and continuous function between topological spaces that has a continuous inverse function. Don’t panic, we will break down this sentence so you can get the full essence of what a homeomorphism is. Read more »

Not A Bug: Killing Is A Feature

by Mike Bendzela

Wastage after hand-thinning a tree that has over-produced apples. Photograph by the author.

It is said that farmers grow things, but that is not right. I view it as a metaphorical statement. The organisms grow themselves as they have been doing for hundreds of millions of years. Farmers stand by and select, tend, and kill. Mostly they kill. It is built into the way the system works. Sometime around 10,000 years ago we discovered how to usurp the powers of natural selection (not that we knew what we were doing) to wrench the earth into providing for us alone rather than following the law of willy-nilly. We have been reaping the whirlwind ever since. The planet is now terraformed to grow large-brained apes and its favorite crops, the wilderness reduced to a shadow of itself, the atmosphere severely perturbed.

Historically, we would rip weeds out of the soil with wood or iron implements and pick off adult bugs by hand. In the last one hundred years or so we’ve come up with many clever ways of suppressing weeds and exterminating arthropods that compete for our crops. This usually involves novel chemical formulations, frequently using petroleum as a feedstock, that when applied to organisms shut down metabolic pathways in plants and impair the nervous systems of insects. For the mammals and birds that feed on crops, there are traps, poisons, barriers, and bullets. Your picturesque Midwestern farm sits atop a charnel house.

We try to outwit nature itself by using “natural” and mechanical methods to avoid and/or eliminate pests, but these are usually insufficient at scale. This is called Integrated Pest Management (IPM). We can select organisms that have natural resistances, provide barriers or even structures to protect them from hazards, plant beneficial companions next to vulnerable crops to suppress pests, release natural predators into the environment that feed on the hungry hordes waiting to decimate our crop. But unlike chemical means which work indiscriminately — they kill every pest they touch — IPM is not so thorough and is a lot of work on top of it. In the end, a farmer will resort to chemical means to get a crop through the season. Read more »

Mrs. Doctor

by Carol A Westbrook

I was the first resident to become pregnant and deliver a child at the University of Chicago–perhaps in any medical residency in the country at the time. It was 1979. I had suffered several months of “internship amenorrhea” before I realized I might be pregnant; a trip to the ED to sneak a pregnancy test confirmed my suspicions. By then I was 16 weeks along.

I imagined that other residents in similar situations would have left their medical training for motherhood; others would have terminated the pregnancy and then continued on with their training.  In 1979, abortions weren’t restricted as they are today, but I had a (failed) IUD in place in the cervix, which made termination a bit riskier. After discussion with my husband (also a medical student) we decided to carry the pregnancy to term; we had planned to eventually have a family, we might as well continue since we already had a start. We were thrilled and delighted, and terrified.

One reason that pregnancy and motherhood were uncommon among medical students in1979 was that the percentage of female med students was low, only about 24% of the entering class. But by 2018-2019 the gap between men and women was beginning to close, and the distribution is now about equal.

Still, until recently, medical schools conducted themselves as if the student body were primarily male. At a recent reunion, the women in my class discussed the problems related to this perception. These problems are due to inequalities in facilities and in women being “outsiders” – they will never become part of the men’s “club.” Read more »
