How Mathematics Changed Me

Alec Wilkinson at The New Yorker:

I did not expect that studying a childhood discipline would lead me to wonder about divine matters, but the possibility of a divine entity is threaded throughout mathematics, which, in its essence, so far as I can tell, is a mystical pursuit, an attempt to claim territory and define objects seen only in the minds of people doing mathematics. Why do I care about abstract possibilities and especially about God, when I have no idea what such a thing might be? A concept? An actual entity? Something hidden but accessible, or forever out of reach? Something once present and now gone? Something that ancient people appear to have experienced at close hand?

I seem temperamentally drawn to the idea of a divinity. As a child, I sometimes had the feeling of an accompanying presence, usually when I was by myself in the woods, a feeling of something infinite behind everything.

Embryos with DNA from three people develop normally

Yvaine Ye from Nature:

When the first baby to be conceived using a technique that mixes genetic material from three people was born, in 2016, scientists worried that the procedure had not been studied to show it was safe. Now, scientists in China have conducted the first comprehensive study of the technique in early-stage human embryos, and report that it seems does not seem to affect their development1.

Techniques for using genetic material from three people to make embryos are designed to prevent mothers with defects in their mitochondria — the organelles that provide cells with energy — from passing them on to their children. Mitochondria contain their own DNA, and children inherit all of their mitochondria from their mother.

“Mitochondrial replacement therapy is a controversial field,” says study co-author Wei Shang, an obstetrician and gynaecologist at the Chinese PLA General Hospital in Beijing. “With our research, we hope to provide a foundation for the development of the technique.”

John Waters on Filmmaking, Felonies, Fox News, and Fucking

Conor Williams in the Los Angeles Review of Books:

While his filmography is now iconic — his mainstream hit Hairspray (1988) has spawned both a remake and an acclaimed musical — the 76-year-old provocateur hasn’t made a picture since 2004. Waters has instead occupied himself with other projects, namely fine art and writing. His more recent books include Carsick: John Waters Hitchhikes Across America (2014) and Mr. Know-It-All: The Tarnished Wisdom of a Filth Elder (2019). The so-called “filth elder” has now written his first novel, Liarmouth: A Feel-Bad Romance, released this May by Macmillan Publishers.

To celebrate this latest endeavor, Waters speaks with me over the phone from his getaway in Provincetown, Massachusetts. Winding down to the end of a whirlwind press tour, he sounds relaxed. Provincetown, after all, has become something of another home to him over the years, his first home being, famously, the city of Baltimore. He speaks softly, but his voice retains its charismatic warmth.

Making computer chips act more like brain cells

Kurt Kleiner in Knowable Magazine:

The human brain is an amazing computing machine. Weighing only three pounds or so, it can process information a thousand times faster than the fastest supercomputer, store a thousand times more information than a powerful laptop, and do it all using no more energy than a 20-watt lightbulb.

Researchers are trying to replicate this success using soft, flexible organic materials that can operate like biological neurons and someday might even be able to interconnect with them. Eventually, soft “neuromorphic” computer chips could be implanted directly into the brain, allowing people to control an artificial arm or a computer monitor simply by thinking about it.

Like real neurons — but unlike conventional computer chips — these new devices can send and receive both chemical and electrical signals.

Why virtue signaling isn’t the same as virtue – it actually furthers the partisan divide

Christopher Beem in The Conversation:

In a speech on July 23, 2022, before the Conservative Political Action Committee, or CPAC, Sen. Ted Cruz introduced himself to the audience with the words, “My name is Ted Cruz and my pronoun is kiss my ass.”

In 2019, the Vermont College of Fine Arts appealed to a different group. They replaced the term alumni – which is derived from the Latin masculine plural but traditionally used to refer to all graduates of the school – with alumnx. In its statement, the college said that dropping the traditional term “alumni” was “a clear step toward exercising more intentional language, which we strive to implement in all aspects of college life.”

These statements are very different, of course. One is explicitly inclusive, designed to demonstrate that everyone who graduated from the school, irrespective of their gender, is included and respected. The other crudely denigrates the very attitudes expressed in the second example.

But for all their differences, both are examples of what has come to be called “virtue signaling” – an act that implicitly claims that the speaker has made a determination about some important moral question and wants to signal to others where they come down.

Empire of The Scalpel

From Delancey Place:

Physics professor Wilhelm Röntgen made an unexpected discovery when he blasted electrons from one electrode to another:

“In the mid-fall of 1895, Wilhelm Röntgen, a physics professor at Wurzburg, Ger­many, was working in a darkened laboratory with an electron tube — a vacuum glass cylinder that blasted electrons from one electrode to another — when he observed a strange phenomenon. An invisible energy that radiated from the tube had pen­etrated layers of surrounding cardboard and produced a faint green glow on a nearby fluorescent screen. Röntgen experimented with other materials (e.g., paper, rubber, and wood) that he wrapped around the tube but found the X-rays (he termed his discovery ‘X-rays’ because their composition was unknown) passed through all sub­stances except for lead. The emissions also darkened photographic plates and, as an experiment, Röntgen had his wife place her hand between the source of the X-rays and a plate. To their amazement, the bones in her hand were distinctly outlined. The findings were so startling that Röntgen’s report on ‘shadow pictures’ soon appeared in a scientific periodical and, by early 1896, was translated and published in the United States.

Wednesday Poem

Modern Fiction

First book assigned in Modern Fiction
is Joseph Conrad’s The Nigger of the Narcissus.

The professor: dandelion lady
tall & thin, an old head capped

in gray-blonde wisps, spits
the hard R from her chest day one,

then again day two, then switches
to the Conrad novel every other time

like she’s not sure if there’s a max
before graves beneath her feet—below floor

and stair and brick—snap,
reach high, and drag down.

Tour guides say Thomas Jefferson went here,
but none detail the dense

death that shrouds
Williamsburg grounds,

the dead who live well
and those who stay dead.

Thomas Jefferson is a modern fiction.
The students here call him TJ,

his statue fixed to Old Campus like a sundial
telling no time but these, Read more »

On Carpets

Dan Handel at Cabinet Magazine:

The most striking thing about this remarkable surface was how easy it was to ignore. It flooded the entire floor surface so perfectly that it just seemed natural that you would glide on this cornucopia of shapes and textures, which made no attempt to reference the space of the hotel or the urban context around it. There was something else. Spending enough time observing the space made it clear that the carpet works in support of the hotel’s organization, in setting an atmosphere, and in moving people in inexplicable ways. “Why does it look like that?” was therefore followed by “What does it do?” during that long afternoon of carpet watching. As it turned out, there were no simple answers. The historians were not alone in their ignorance: front desk clerks and hotel managers, perfectly capable of guiding you through the thickets of the city’s urban history or recommending the right drink at the bar, had no idea who designed the carpet and with what motives.

On Criticism

Elizabeth Schambelan at Artforum:

Criticism in the broadest sense is a key tactic for maintaining a nonrigid, noncomplacent orientation toward the world. You’re always stepping back and looking at everything afresh, never taking anything for granted, never turning a blind eye to your own complicities and flaws—ideally, anyway. We are committed to criticism not as a way of formulating value judgments but as a literary-artistic-intellectual practice that has a relationship to irony as defined by Friedrich Schlegel: “clear consciousness of an eternal agility.” It’s also related to Adorno’s comment that “it is part of morality not to be at home in one’s home.” The common denominator that links irony with Adorno’s remark is this: Never get too comfortable, never be quite congruent with yourself, and never assume anything else is entirely congruent with itself.

Ten Questions About the Hard Limits of Human Intelligence

David H Wolpert in Aeon:

Despite his many intellectual achievements, I suspect there are some concepts my dog cannot conceive of, or even contemplate. He can sit on command and fetch a ball, but I suspect that he cannot imagine that the metal can containing his food is made from processed rocks. I suspect he cannot imagine that the slowly lengthening white lines in the sky are produced by machines also made from rocks like his cans of dog food. I suspect he cannot imagine that these flying repurposed dog food cans in the sky look so small only because they are so high up. And I wonder: is there any way that my dog could know that these ideas even exist? It doesn’t take long for this question to spread elsewhere. Soon I start to wonder about concepts that I don’t know exist: concepts whose existence I can never even suspect, let alone contemplate. What can I ever know about that which lies beyond the limits of what I can even imagine?

Attempting to answer this question only leads us to more questions. In this essay, I’m going to run through a sequence of 10 queries that provide insight into how we might begin conceiving of what’s at stake in such a question and how to answer it – and there is much at stake.

Sean Carroll’s Mindscape Podcast: Brad DeLong on Why the 20th Century Fell Short of Utopia

Sean Carroll in Preposterous Universe:

People throughout history have imagined ideal societies of various sorts. As the twentieth century dawned, advances in manufacturing and communication arguably brought the idea of utopia within our practical reach, at least as far as economic necessities are concerned. But we failed to achieve it, to say the least. Brad DeLong’s new book, Slouching Towards Utopia: An Economic History of the Twentieth Century, investigates why. He compares the competing political and economic systems that dominated the “long 20th century” from 1870 to 2010, and how we managed to create such enormous wealth and still be left with such intractable problems.

How Mikhail Gorbachev Became the Most Reviled Man in Russia

Jeffrey Sommers in CounterPunch:

Mikhail Gorbachev presented a figure of Greek tragedy proportions. Possessing good intentions and intellectual curiosity, Gorbachev nonetheless became the most reviled man in Russia, following the USSR’s demise. Yet, with Gorbachev, his worst qualities were connected to his best. Gorbachev was the wrong man at the wrong time to resolve the contradictions created by the Stalinist and then Brezhnev bureaucratic model of really-existing socialism in the Soviet Union. Increasingly hated at home, Gorbachev was beloved by world leaders in the “West” as the man who peacefully (at least by the comparative metrics of collapsing empires) unwound the USSR, even if trying to save its all-union character. Meanwhile, for China, Gorbachev delivered lessons in what not to do when reforming a sclerotic post-Stalinist system requiring economic reforms, if not transformation.

What happened when the USSR produced its first post-World War II leader untethered to Joseph Stalin (and those he appointed)?

Biden Laid the Trap. Trump Walked Into It

David Frum in The Atlantic:

In 2016, Hillary Clinton warned that Donald Trump was a fool who could be baited with a tweet. This past Thursday night, in Philadelphia, Joe Biden upped the ante by asking, in effect: What idiot thing might the former president do if baited with a whole speech? On Saturday night, the world got its answer.

For the 2022 election cycle, smart Republicans had a clear and simple plan: Don’t let the election be about Trump. Make it about gas prices, or crime, or the border, or race, or sex education, or anything—anything but Trump. Trump lost the popular vote in 2016. He lost control of the House in 2018. He lost the presidency in 2020. He lost both Senate seats in Georgia in 2021. Republicans had good reason to dread the havoc he’d create if he joined the fight in 2022.

Why Japan is building smart cities from scratch

Tim Hornyak in Nature:

By 2050, nearly 7 out of 10 people in the world will live in cities, up from just over half in 2020. Urbanization is nothing new, but an effort is under way across many high-income countries to make their cities smarter, using data, instrumentation and more efficient resource management. In most of these nations, the vast majority of smart-city projects involve upgrades to existing infrastructure. Japan stands out for its willingness to build smart communities from scratch as it grapples with a rapidly ageing population and a shrinking workforce, meaning that there are fewer people of working age to support older people.

In 2021, the proportion of Japan’s population aged 65 and over hit 29.1%, the highest in the world. By 2036 it will be 33%. Regional cities, especially, face a long, slow economic decline. As a resource-poor, disaster-prone country, Japan has also had to pursue energy efficiency and resilience following the 2011 Tohoku earthquake and the tsunamis it triggered. The resulting meltdowns at the Fukushima Daiichi nuclear power plant initially encouraged a shift away from nuclear power, which accounted for less than 4% of Japan’s energy use in 2020. However, there are growing calls, led by Japan’s ruling Liberal Democratic Party, for some reactors to be reopened to provide energy security and tackle rising fuel prices.

Good liberals are not Rawlsian liberals

Charles Blattberg in The Hedgehog Review:

Imagine someone told you that politics is a “great game,” that when citizens respect just principles, they do so “in much the same way that players have the shared end to execute a good and fair play of the game.” You would probably wonder if they meant it, if they really believed that civic duties resemble those acquired when “we join a game, namely, the obligations to play by the rules and to be a good sport.” You would because, for most people, politics is a serious business.

No doubt, this is because the stakes are so high: Political decisions can affect how millions live or die. That is why we also take war so seriously. Today, it seems astonishing that nineteenth-century Prussian military theorist Carl von Clausewitz felt it necessary to insist, in his canonical work On War (1832), that “war is no pastime; it is no mere joy in daring and winning, no place for irresponsible enthusiasts. It is a serious means to a serious end.” Especially since the devastations of the twentieth century, we have had no need of such an admonition.

Then why have so few objected to the Rawlsian metaphors that I just quoted? John Rawls (1921–2002) was the most important political philosopher of the previous century, and perhaps even of this one. Yet he was also someone for whom the good of justice was “no more mysterious than that members of an orchestra, or players on a team, or even both teams in a game, should take pleasure and a certain (proper) pride in a good performance, or in a good play of the game, one that they will want to remember.” How can this be?

How Isaac Newton Discovered the Binomial Power Series

Steven Strogatz in Quanta:

Isaac Newton was not known for his generosity of spirit, and his disdain for his rivals was legendary. But in one letter to his competitor Gottfried Leibniz, now known as the Epistola Posterior, Newton comes off as nostalgic and almost friendly. In it, he tells a story from his student days, when he was just beginning to learn mathematics. He recounts how he made a major discovery equating areas under curves with infinite sums by a process of guessing and checking. His reasoning in the letter is so charming and accessible, it reminds me of the pattern-guessing games little kids like to play.

It all began when young Newton read John Wallis’ Arithmetica Infinitorum, a seminal work of 17th-century math. Wallis included a novel and inductive method of determining the value of pi, and Newton wanted to devise something similar.
