The poor reap what the luxury belief class sows

February 9th, 2024

Troubled by Rob HendersonKay S. Hymowitz reviews Rob Henderson’s Troubled: A Memoir of Foster Care, Family, and Social Class:

In Rob Henderson’s first recounted memory in his new memoir, Troubled, he is three years old, screaming in terror and clinging to his mother as two policemen wrestle handcuffs onto her wrists. He had no idea why this was happening, of course; the scuffle likely had something to do with his mother’s incorrigible drug addiction. A Korean-born college dropout, she relied on prostitution to support her habit. When she and Rob weren’t living in a car, she would tie him to a chair in the apartment to attend to her customers. Her other two boys, Rob’s brothers, had different fathers; Rob would never know them or learn what became of them.

[…]

His life took a turn for the better when, lacking alternatives, he enlisted in the Air Force. Conventional wisdom has it that boys like Rob learn self-discipline and responsibility from military life, but Henderson has a different take. The military didn’t “transform” him, he argued — it merely stopped him from becoming a self-destructive basket case. Most kids with his background are not so lucky.

[…]

Later, he was accepted at Yale University. For all elite universities’ problems — Henderson spotted them quickly — Yale was rocket fuel for his under-exercised brain. Henderson sounded like the kind of student that professors pray for but rarely see: mature, mindful, and hungry for knowledge. He didn’t just “do the reading;” he tested the ideas he encountered against own experiences and observations.

Class by Paul Fussell

Henderson’s restless mind had been particularly stimulated by a 1983 book called Class: A Guide Through America’s Status System by the iconoclastic historian-critic Paul Fussell. Class opens Henderson’s eyes to the distance between forlorn places like Red Bluff and the towns of his Yale classmates’ upper middle-class upbringings. He noticed more than the obvious markers of privilege, like the students in $900 Canadian Goose jackets who strode around campus; he discovered the more subtle ways people like him were kept from moving up. Voguish words like “heteronormative” and “cisgender,” for instance, signaled that the speaker was a member of the educated class. Fussell had remarked that upper-class people often name their pets after literary or historical figures to flaunt their education. Sure enough, one of the first Yalies Henderson met had a pet cat named “Learned Claw,” a play on the name of jurist Learned Hand.

Henderson became fascinated by “class divides and social hierarchies,” adding Pierre Bourdeau, Emile Durkheim, and Thorstein Veblen to his reading list. His primary source, however, was Yale itself. In Red Bluff, hardly anyone went to college or even aspired to go; at Yale, he watched The Sopranos and was struck by Carmella’s dedication to getting daughter Meadow into Columbia. College, he realized, was the most powerful class signifier of all.

Troubled’s penultimate chapter, which might be subtitled “What I Learned at Yale,” is a tour de force that in a more rational world would be required reading for all incoming college students at elite schools. In it, Henderson developed his now widely cited concept of “luxury beliefs.” Yale students, appearing aware of their own advantages and compassionate to the downtrodden, would proudly repeat ideas that the boy from Red Bluff knew would harm the marginalized. Many of the parents of his childhood friends were drug addicts, yet his college peers cheered on drug liberalization, for example. And why not? It seemed enlightened and cost people like them nothing.

For Henderson, the most painful luxury beliefs were those that undermined families and the childhood stability he had so desperately craved. “Monogamy is kind of outdated,” a Yale graduate announced. She admitted that she had grown up with both parents and hoped someday to marry — monogamously, of course. In such people’s minds, to acknowledge the benefits of two-parent families and the stability that they are more likely to confer is to be insensitive to less fortunate families with different family structures. This attitude gets things backward, Henderson writes: “It’s cruel to validate decisions that inflict harm, especially on those who had no hand in the decision—like young children.” Luxury believers pay no price for ignoring the harms they endorse. In fact, it’s the opposite — they gain social currency at places like Yale. “The poor reap what the luxury belief class sows,” Henderson said.

It will not be feasible to match China fighter for fighter and missile for missile

February 8th, 2024

During a July 2023 wargame, the Mitchell Institute tasked experienced operators, technologists, and engineers from the Air Force and defense industry to assess how a mix of uncrewed CCA (collaborative combat aircraft) and crewed combat aircraft could achieve air superiority over a peer aggressor (China):

One of the most important insights is the potential to use CCA as lead forces to help disrupt and suppress China’s advanced integrated air defense system (IADS), improve the lethality and survivability of the Air Force’s counterair forces, and magnify the service’s capacity to project combat mass into highly contested battlespaces. Experts agreed it will not be feasible to match China fighter for fighter and missile for missile in today’s battlespace, given the Air Force’s fighter force is now less than half the size it was in 1991. Accordingly, all three wargame teams proposed CONOPS that initially used CCA at scale to disrupt China’s IADS and level the playing field against the PLAAF.

[…]

All three wargame teams also chose to use a mix of CCA variants designed as airborne sensors, decoys, jammers, or weapon launchers to disrupt and stimulate the PLA’s IADS, locate its critical nodes, and begin to attrit threats to support crewed aircraft operations. Dispersing these functions across a mix of CCA would improve the Air Force’s operational resiliency and increase the number of airborne targets an adversary’s forces must attack. By design, lower-cost CCA may lack the mission systems and full functionalities of 5th generation fighters. However, an adversary has no reliable way of differentiating between how CCA are equipped and must address them all as threats. The key is understanding that CCA — in the same way remotely piloted aircraft (RPA) sensor-shooters pioneered a new way of conducting precision strikes — will be more than intelligence, surveillance, and reconnaissance (ISR) information gatherers.

Another insight is that CCA could increase the Air Force’s capacity to generate lethal mass for counterair operations. Appropriately equipped CCA can perform as force multipliers that increase the number of sensors and weapons the Air Force can project into contested battlespaces. CCA could also extend the sensor and weapon ranges of stealthy crewed aircraft they team with, increasing their lethality and survivability. This will require designing CCA with enough survivability to ensure they can reach their air-to-air weapons launch points in contested environments. Using CCA to reduce attrition of Air Force fighters and their crews would also have a major force multiplying effect over the course of a campaign — a key consideration given that DOD-mandated force cuts over the last 30 years caused the Air Force to divest its combat attrition reserves.

[…]

CCA could multiply the Air Force’s diminished combat inventory in another way: by enabling some of its non-stealthy combat aircraft to engage in the fight for air superiority in highly contested environments. For instance, notional CCA designs available to Mitchell Institute’s wargame experts included a long-range, air-launched design that carried two air-to-air weapons or four 250-pound class Small Diameter Bombs (SDBs). The experts used 4th generation F-15EXs and B-52 bombers operating outside the range of China’s IADS to launch these counterair CCA into contested area

Experts participating in Mitchell’s wargame also preferred to use a mix of lower-cost CCA they classified as expendable systems and more capable, moderate-cost CCA that can be recovered and regenerated for additional sorties or attritted if mission needs require in highly contested battlespaces. Experts chose to use expendable CCA in significant numbers during the first few days of their campaigns as airborne decoys, jammers, active emitters, and other ways that risked their loss in highly contested environments. And since these notional CCA could be ground-launched by rockets without the need to use runways, wargame experts chose to pre-position them at dispersed locations in the Philippines and Ryukyu Islands to improve the resiliency of the Air Force’s combat sortie generation operations. As their campaigns progressed, experts shifted toward using a larger number of moderate-cost recoverable/attritable CCA that carried larger payloads of weapons and could return to their forward operating locations to regenerate for additional sorties.

Finally, wargame experts suggested there is a need to develop concepts for operating CCA with other uncrewed aerial vehicles for counterair missions rather than solely using them as adjuncts for crewed aircraft. Of note, operating CCA in this way would require providing them with more advanced autonomy and other technologies that add to their cost.

It is a perfect target for digital destruction

February 7th, 2024

Burn Book by Kara SwisherKara Swisher was a reporter at the Washington Post in the early 1990s, where, at age 30, she was the “young” person in the newsroom, so she had to cover digital media:

During that period, I made one prediction that started coming true much more quickly than even I expected. This was about the end of old media, starting with the destruction of one of its most important economic pillars: the classified ads in newspapers.

In 1995, a quirky programmer in San Francisco named Craig Newmark started emailing friends a list of local events, job opportunities, and things for sale. The next year, he turned Craigslist into a web-based service and eventually started expanding it all over the country and the world.

It was clear this list was a giant killer, and I told everyone who would listen to me at the Post that we needed to put all the money, all the people, and all the incentives into digital. I insisted that the bosses had to make readers feel like digital was the most important thing. But the bosses never did because the business they knew was the physical paper. I relayed my worries about the turtle pace of digital change many times to the Washington Post Company’s affable CEO, Don Graham, the son of legendary publisher and surprisingly entertaining badass Katharine Graham. Don Graham was inexplicably humble and even sheepish about his power. The very worst thing that Graham — always apologetic for having interrupted me, as I strafed big retail advertisers in my stories about the sector’s decline locally — would say to me was “Ouch.” Then he would saunter away from my desk with a jaunty wave. And while Graham was interested when I talked about what Newmark was doing, he laughed when I told him that Craigslist would wipe out his classifieds business.

“You charge too much, the customer service sucks, it’s static, and most of all, it doesn’t work,” I lectured him about this business, which was crucial to his bottom line. “It will disappear as an analog product, since it is a perfect target for digital destruction. You’re going to die by the cell and not even know it until it’s over and you’re dead on the ground.”

Don smiled at me with a kindness I certainly did not deserve at that moment. “Ouch,” he said.

The Post, of course, is now owned by a tech mogul, Jeff Bezos, and other Silicon Valley machers have taken over or invested heavily in legacy media, but they have not prevented its relentless decline, or the hemorrhaging of thousands of jobs from the industry in just the past few years, as the digital world has both sucked up and diminished print business models.

More missiles have been fired at known SIM cards than at recognized individuals

February 6th, 2024

Swarm Troopers by David HamblingInsurgents may be tracked and targeted by their mobile phones, David Hambling notes (in Swarm Troopers):

It has been suggested that more missiles have been fired at known SIM cards than at recognized individuals. In recent years agents in the field have marked targets for drone strikes with miniature radio beacons. A mobile phone left under a seat can perform the same function. The Taliban in Afghanistan have executed alleged spies who left electronic devices concealed in empty cigarette packets. Taliban commanders now know to leave their vehicles guarded at all times to prevent tracking devices from being attached.

[…]

Other types of tagging are passive. One approach is to shower the target with a fine dust of “quantum dots”, tiny specks of semiconducting crystal. These are invisible to the naked eye but can be detected from long range with the aid of an infrared laser illuminator. Different batches of dots can be given specific codes, so a tagged individual or vehicle can be identified days later from long range.

Other tagging technologies include dyes and inks visible only through special viewers. One DARPA document even suggested that an additive could be introduced to the target’s shampoo so they could be identified and tracked. It is not clear whether this idea was ever developed.

We can read the scrolls

February 5th, 2024

Vesuvius ChallengeOn March 15th, 2023, Nat Friedman, Daniel Gross, and Brent Seales launched the Vesuvius Challenge, and now they are announcing the Grand Prize winners:

Two thousand years ago, a volcanic eruption buried an ancient library of papyrus scrolls now known as the Herculaneum Papyri.

In the 18th century the scrolls were discovered. More than 800 of them are now stored in a library in Naples, Italy; these lumps of carbonized ash cannot be opened without severely damaging them. But how can we read them if they remain rolled up?

[…]

Scrolls from the Institut de France were imaged at the Diamond Light Source particle accelerator near Oxford. We released these high-resolution CT scans of the scrolls, and we offered more than $1M in prizes, put forward by many generous donors.

[…]

Our team of eminent papyrologists worked day and night to review 15 columns of text in anonymized submissions, while the technical team audited and reproduced the submitted code and methods.

There was one submission that stood out clearly from the rest. Working independently, each member of our team of papyrologists recovered more text from this submission than any other. Remarkably, the entry achieved the criteria we set when announcing the Vesuvius Challenge in March: 4 passages of 140 characters each, with at least 85% of characters recoverable. This was not a given: most of us on the organizing team assigned a less than 30% probability of success when we announced these criteria! And in addition, the submission includes another 11 (!) columns of text — more than 2000 characters total.

The results of this review were clear and unanimous: the Vesuvius Challenge Grand Prize of $700,000 is awarded to a team of three for their excellent submission. Congratulations to Youssef Nader, Luke Farritor, and Julian Schilliger!

[…]

Scholars might call it a philosophical treatise. But it seems familiar to us, and we can’t escape the feeling that the first text we’ve uncovered is a 2000-year-old blog post about how to enjoy life.

Maybe fire forces growth, and stabbing them only stuns them

February 5th, 2024

Back in August, 1979, issue #29 of Dragon magazine included a game called The Awful Green Things From Outer Space. I never played it, so I didn’t realize it included this interesting game mechanic:

Scattered around the ship are various weapons. However, alien physiology is weird. Maybe fire forces growth, and stabbing them only stuns them.

At the start of each game, the Weapons Display is empty, but the first time a weapon is used, a token is drawn to determine its effect on the aliens for the remainder of the game.

This is a silly sci-fi game, but a similar concept was used by the Naval War College in the years before World War 2, so officers could learn how to learn to fight the expected war against the Japanese:

Naval War College students certainly wanted to win their big “capstone” wargame at the end of their school year. As students have always done, they asked those who graduated before them for advice, or in the vernacular of the US military, “gouge.” Graduates were happy to provide advice: “Try to engage the Japanese at night, they are blind; watch out for their torpedoes though, they are killers; fortunately, though, their ships sink like rocks after the lightest of battering.” However, when they talked to someone who graduated in a different year, they learned “Avoid night engagements, the Japs are incredible; and their ships are so rugged they can really close in and slug it out; at least you don’t have to worry about their tinker toy torpedoes.” Slowly it dawned on the students — the faculty was giving the Japanese different strengths and weaknesses in each wargame!

Rockets had an extremely high idiot index

February 4th, 2024

Elon Musk by Walter Isaacson“I was pretty mad,” Elon Musk said about his failed attempt to buy Russian rockets, “and when I get mad I try to reframe the problem.” Walter Isaacson explains (in his biography of Elon) how Musk employed first-principles thinking:

This led him to develop what he called an “idiot index,” which calculated how much more costly a finished product was than the cost of its basic materials. If a product had a high idiot index, its cost could be reduced significantly by devising more efficient manufacturing techniques.

Rockets had an extremely high idiot index. Musk began calculating the cost of carbon fiber, metal, fuel, and other materials that went into them. The finished product, using the current manufacturing methods, cost at least fifty times more than that.

[…]

So on the flight home, he pulled out his computer and started making spreadsheets that detailed all of the materials and costs for building a midsize rocket.

[…]

“Hey, guys,” he said, showing them the spreadsheet, “I think we can build this rocket ourselves.” When Cantrell looked at the numbers, he said to himself, “I’ll be damned — that’s why he’s been borrowing all my books.”

He was the first Corsican to attend the École Royale Militaire

February 3rd, 2024

Napoleon by Andrew Roberts Napoleon’s education in France made him French, Andrew Roberts explains (in his biography of the Emperor of the French):

His bursary grant (the equivalent of a curate’s stipend) was dated December 31, 1778, and he started at the ecclesiastical seminary run by the bishop of Autun the next day. He wasn’t to see Corsica again for almost eight years. His name appeared in the school registry as ‘M. Neapoleonne de Bonnaparte’. His headmaster, the Abbé Chardon, recalled him as ‘a thoughtful and gloomy character. He had no playmate and walked about by himself … He had ability and learned quickly … If I scolded him, he answered in a cold, almost imperious tone: “Sir, I know it.” It took Chardon only three months to teach this intelligent and determined lad, with a will to learn, to speak and read French, and even to write short passages.

Having mastered the requisite French at Autun, in April 1779, four months shy of his tenth birthday, Napoleon was admitted to the Royal Military School of Brienne-le-Château, near Troyes in the Champagne region. His father left the next day, and as there were no school holidays they were not to see each other again for three years. Napoleon was taught by the Minim order of Franciscan friars as one of fifty royal scholars among 110 pupils. Despite being a military academy, Brienne was administered by the monks, although the martial side of studies were conducted by outside instructors. Conditions were spartan: students had a straw mattress and one blanket each, though they weren’t beaten.

[…]

His eight hours of study a day included mathematics, Latin, history, French, German, geography, physics, fortifications, weaponry, fencing, dancing and music (the last three an indication that Brienne was also in part a finishing school for the noblesse). Physically tough and intellectually demanding, the school turned out a number of very distinguished generals besides Napoleon, including Louis-Nicolas Davout, Étienne Nansouty, Antoine Phélippeaux and Jean-Joseph d’Hautpoul. Charles Pichegru, the future conqueror of Holland and royalist plotter, was one of the school’s instructors.

Napoleon excelled at mathematics. ‘To be a good general you must know mathematics,’ he later observed, ‘it serves to direct your thinking in a thousand circumstances.’ He was helped by his prodigious memory. ‘A singular thing about me is my memory,’ he once boasted. ‘As a boy I knew the logarithms of thirty or forty numbers.’ Napoleon was given permission to take maths classes earlier than the prescribed age of twelve, and soon mastered geometry, algebra and trigonometry. His weakest subject was German, which he never mastered; another weak subject, surprisingly for someone who so adored ancient history, was Latin. (He was fortunate not to be examined in Latin until after 1780, by which time it was clear that he would be going into the army or navy and not the Church.) Napoleon also excelled at geography. On the very last page of his school exercise book, following a long list of British imperial possessions, he noted: ‘Sainte-Hélène: petite île.’

[…]

Napoleon borrowed many biographies and history books from the school library, devouring Plutarch’s tales of heroism, patriotism and republican virtue. He also read Caesar, Cicero, Voltaire, Diderot and the Abbé Raynal, as well as Erasmus, Eutropius, Livy, Phaedrus, Sallust, Virgil and the first century BC Cornelius Nepos’ Lives of the Great Captains, which included chapters on Themistocles, Lysander, Alcibiades and Hannibal. One of his school nicknames — ‘the Spartan’ — might have been accorded him because of his pronounced admiration for that city-state rather than for any asceticism of character. He could recite in French whole passages from Virgil, and in class he naturally took the side of his hero Caesar against Pompey.

[…]

A contemporary recalled Napoleon withdrawing to the school library to read Polybius, Plutarch, Arrian (‘with great delight’) and Quintus Curtius Rufus (for which he had ‘little taste’).

[…]

In 1781, Napoleon received an outstanding school report from the Chevalier de Kéralio, the under-inspector of military schools who, two years later, recommended him for the prestigious École Militaire in Paris with the words, ‘Excellent health, docile expression, mild, straightforward, thoughtful. Conduct most satisfactory; has always been distinguished for his application in mathematics … This boy would make an excellent sailor.’ His clear intellectual superiority is unlikely to have helped his popularity with his classmates, who nicknamed him La Paille-au-Nez (‘straw up the nose’), which rhymed with ‘Napoleone’ in Corsican. He was teased for not speaking refined French, for having a father who had had to certify to his nobility, for coming from a conquered nation, for having a relatively large head on a thin frame and for being poorer than most of his school contemporaries. ‘I was the poorest of my classmates,’ he told a courtier in 1811, ‘they had pocket-money, I never had any. I was proud, I was careful not to show it … I didn’t know how to smile or play like the others.’ When he spoke in later life about his schooldays, he remembered individual teachers he had liked, but few fellow pupils.

[…]

Napoleon took his final exams at Brienne on September 15, 1784. He passed easily, and late the following month he entered the École Royale Militaire in Paris, on the left bank of the Seine. This was a far more socially elevated institution than Brienne. There were three changes of linen a week, good meals and more than twice as many servants, teachers and staff — including wigmakers — as students. There were also three chapel services a day, starting with 6 a.m. Mass. Although strangely the history of warfare and strategy weren’t taught, the syllabus covered much the same subjects as at Brienne, as well as musketry, military drills and horsemanship. It was in fact one of the best riding schools in Europe.

[…]

Of the 202 candidates from all of France’s military schools in 1784, a total of 136 passed their final exams and only 14 of these were invited to enter the artillery, so Napoleon had been selected for an elite group. He was the first Corsican to attend the École Royale Militaire,

[…]

Napoleon took classes from the distinguished trio of Louis Monge (brother of the mathematician-chemist Gaspard), the Marquis de Laplace, who later became Napoleon’s interior minister, and Louis Domairon, who taught him the value of ‘haranguing’ troops before battles. (Shorn of its English meaning, which implies a prolonged rant, a French harangue could mean an inspiring speech, such as Shakespeare puts in Henry V’s mouth or Thucydides in the mouth of Pericles, a skill at which Napoleon was to excel on the battlefield, but not always in public assemblies.) At the École, Napoleon encountered the new thinking in French artillery practice introduced by Jean-Baptiste de Gribeauval after the Seven Years War. (Defeat had been, as it is so often in history, the mother of reform.) He also studied General Comte Jacques de Guibert’s revolutionary Essai général de tactique (1770): ‘The standing armies, a burden on the people, are inadequate for the achievement of great and decisive results in war, and meanwhile the mass of the people, untrained in arms, degenerates … The hegemony over Europe will fall to that nation which becomes possessed of manly virtues and creates a national army.’ Guibert preached the importance of speed, surprise and mobility in warfare, and of abandoning large supply depots in walled cities in favour of living off the land. Another of Guibert’s principles was that high morale — esprit de corps — could overcome most problems.

[…]

He took his final examinations early, coming forty-second out of fifty-eight candidates — not so poor a result as it may seem given that he sat the exams after only one year rather than the normal two or three. He could now dedicate himself to his military career, and to the serious financial problems Carlo had left. Napoleon later admitted that these ‘influenced my state of mind and made me grave before my time’.

[…]

At sixteen he was one of the youngest officers, and the only Corsican to hold an artillery commission in the French army. Napoleon always recalled his years at Valence as impecunious — his room had only a bed, table and armchair — and sometimes he had to skip meals in order to afford books, which he continued to read with the same voracious appetite as before.

[…]

By late May 1788 Napoleon was stationed at the School of Artillery at Auxonne in eastern France, not far from Dijon. Here, as when he was stationed with his regiment at Valence, he ate only once a day, at 3 p.m., thereby saving enough money from his officer’s salary to send some home to his mother; the rest he spent on books. He changed his clothes once every eight days. He was determined to continue his exhaustive autodidactic reading programme and his voluminous notebooks from Auxonne are full of the history, geography, religion and customs of all the most prominent peoples of the ancient world, including the Athenians, Spartans, Persians, Egyptians and Carthaginians. They cover modern artillery improvements and regimental discipline, but also mention Plato’s Republic, Achilles and (inevitably) Alexander the Great and Julius Caesar.

Four nuclear-powered merchant ships have been built so far

February 2nd, 2024

Today, 200 nuclear reactors are operating on 160 vessels, mostly naval ships and submarines, but soon they could run on cargo ships, too:

Four nuclear-powered merchant ships have been built so far, all of them government-led projects begun mostly for developmental and testing reasons rather than purely commercial ones. The first was the American NS Savannah, built in the late 1950s at a cost of $46.9 million (an eye-popping $495 million today). It was in service from 1962 to 1972, but its pressurized light-water reactor (LWR) proved too complex and expensive for the ship to operate profitably. The Russian cargo vessel Sevmorput, commissioned in 1988, is the only nuclear-powered merchant ship still in operation as of early 2024. The other two ships, the Japanese Mutsu (1970) and the German Otto Hahn (1968), were both refitted with diesel engines partway through their service lives.

Nuclear power has been more successfully applied on submarines and ice-breaking vessels. The very first nuclear-powered vessel was the attack submarine USS Nautilus, in 1954, amid the 1950s heyday of nuclear-power research. Hundreds of nuclear reactors have since been used on ships and submarines. Russia currently operates seven nuclear-powered icebreakers.

[…]

“Engines in ordinary ships are the size of houses,” says Emblemsvåg, who is leading NuProShip. And a great deal of space is taken up by fuel: “A container vessel going from Amsterdam to Shanghai requires roughly 4,000 tonnes of fuel.”

An SMR would be much more compact and lightweight. According to Emblemsvåg, a molten-salt reactor — which uses a mixture of thorium and hot liquid salts as both fuel and coolant — would also save about $70 million over the lifetime of a ship, compared with a similar vessel powered by engines that burn diesel fuel (or, more precisely, heavy fuel oil). Another plus for nuclear-propelled ships is easy access to an endless supply of cooling water.

[…]

For ship propulsion, engineers have used pressurized-water reactors because they can produce higher power for a given mass compared with the other kind of light-water reactor, the boiling-water reactor. However, the technology comes with major challenges. They depend on complex control systems that need a technically trained operating crew, and they run on solid fuel rods that need to be replaced every 18 months. There’s also a risk, however slight, that the pressure vessel could explode.

Fourth-generation SMRs avoid all that. Emblemsvåg and the NuProShip team picked three reactor designs after analyzing 93 concepts in the International Atomic Energy Agency’s SMR handbook. One is a thorium-fueled molten-salt reactor. The second is a lead-cooled fast reactor, which replaces the water coolant of traditional reactors with molten lead. The third option, likely closest to market, is a helium gas-cooled reactor that uses a type of fuel called tristructural isotropic (TRISO), consisting of uranium particles encased in ultratough carbide and carbon layers that can handle temperatures above 2,000 °C.

Why are so many NFL quarterbacks blue-eyed?

February 1st, 2024

I knew that Steve Sailer had asked, “Why are so many NFL quarterbacks blue-eyed?” but I hadn’t looked into it, until Razib Khan linked to a 2014 piece:

Intrigued, I did a little research with the help of Google and NFL.com, and it turns out that over 80% of Superbowls have been won by Quarterback with blue eyes, a ratio of over 4 to 1. What’s more, of the twenty-three modern era quarterbacks in the NFL Hall of Fame, twenty-one have light colored eyes. That is not a misprint. That is over 90%. If you were to include guaranteed first ballot HOFer’s Peyton Manning, Bret Favre and Tom Brady, it climbs to an astounding twenty four of twenty six. (In 2014, no quarterbacks were voted as HOF semifinalist; however, of the six quarterbacks eligible, only sky blue-eyed Phil Simms has won a Superbowl, setting a record for completion percentage in the game and winning the Superbowl MVP award).

Only two Hall of Fame quarterbacks have brown eyes, Warren Moon and Otto Graham. For any coach in the NFL (or vegas bookie), this should be a stunning revelation. According to a New York Times article by Douglas Belkin, blue eyes make up less than twenty percent of the people born in the U.S. today, about 1 in 6. Even when you concede the fact that racism played a large part in the earlier days of the NFL (and some would say even now), and therefore use only statics from the population of Caucasian Americans for comparison, blue eyes are still only found at a rate of approximately 34%, or 1 in 3. Only in Estonia and some Scandinavian countries does the percentage of blue eyes even approach that of the NFL Hall of Fame’s 90+%.

[…]

According to my wife, (a certified retinal angiographer who has worked with America’s top retinal surgeons), it is well known amongst eye surgeons and ophthalmologists that there are dramatic physiological differences between light and dark colored eyes. In fact, light eyes, or those with less melanin present, are at a greater risk for macular degeneration as well as reacting very differently to certain stimuli than dark colored eyes. For example, when given dilation drops before an exam or surgery, it is common knowledge that brown eyes require more medication, sometimes up to twice as much, take longer to dilate and stay dilated for a shorter period of time than their lighter colored counterparts. If eye color accounts for this diverse a reaction to a temporary medication like dilation drops, it stands to reason that they would react differently to other stimuli as well, like air temperature or perhaps even the bluish tint of the winter sun. This concept has largely been ignored by the athletic community.

[…]

If any other occupation required a similar visual skill as the NFL quarterback, the men often admiringly referred to as gunslingers, then perhaps actual sharp shooters, or what we might call a sniper today, is a good place to look for validation. As it turns out, it was once common knowledge that the best sharp shooters possessed light colored eyes. In a famous 1890 short story by Ambrose Bierce, An Occurrence at Owl Creek Bridge, the author writes, “He observed that it was a grey eye and remembered having read that grey eyes were keenest, and that all famous marksmen had them.” In reality, it was so well known light colored eyes made for the best snipers that the Canadian military conducted tests in the late 1800’s on the very subject. They not only found lighter eyes seem to perform better as snipers, but certain colors can be seen at great distances better than others resulting in a change of their infantry’s uniform color from red to grey, the very first official camouflage and, what would suddenly appear to be a huge advantage for the Oakland Raiders. (Jim Plunkett finally comes into focus).

Harvard is something of a national institution, and its admissions policies have become everyone’s business

January 31st, 2024

Harvard admissions should be more meritocratic, Steven A. Pinker, Contributing Opinion Writer, opines:

Thanks to its tax-exempt status, federal funding, and outsize role as a feeder school to the American elite, Harvard is something of a national institution, and its admissions policies have become everyone’s business.

Others argue that holistic admissions are necessary to avoid a class of grinds and drudges. But elite universities should be the last to perpetuate this destructive stereotype. It would be ludicrous if anyone suggested that Harvard pick its graduate students or faculty for their prowess in athletics or music or improv comedy, yet these people are certainly no shallower than our undergraduates.

In any case, the stereotype is false. The psychologists Camilla P. Benbow and David Lubinski have found that precocious adolescents with sky-high SAT scores grew up to excel not only in academia, medicine, business, and technology, but also in literature, drama, art, and music.

Instead of “holistic admissions,” I suggest using a transparent formula that is weighted toward test scores and high school grades, adjusting it by whichever other factors can be publicly justified, such as geographic and socioeconomic diversity, and allowing for human judgment in exceptional cases. (I recognize the arguments for including race, but that has been judged unconstitutional, so the issue is moot.)

Hellfire does not tidily disintegrate the target as in a video game

January 30th, 2024

Swarm Troopers by David HamblingCofer Black, head of the CIA’s counterterrorist Center, requested that the Predator be armed, David Hambling reports (in Swarm Troopers), and USAF General John Jumper requested a demonstration of a Predator that could “find a target, then eliminate it”:

Hellfire was chosen because it was a proven, mature missile with many years of successful service. In fact, mature is something of an understatement: Hellfire was positively middle-aged, dating back to the Nixon administration in 1974.

[…]

Hellfire has laser guidance, so the target needs to be marked with a laser designator right up until the missile hits. It is highly accurate, usually hitting within half a meter of the aim point, but it can take a while to arrive. Hellfire is faster than the speed of sound, but fired from a range of six miles, it still takes about twenty seconds to reach the target.

[…]

Hellfire is uncomfortably large to hang off a Predator but small compared to anything else available in the inventory. At the time, the Air Force’s smallest guided bomb was five hundred pounds.

[…]

The other challenge when firing a Hellfire from a Predator is the unavoidable two-second time lag caused by satellite communications. This means the laser spot effectively takes two seconds to move, so the Predator can only engage a stationary target in this mode. To hit a moving target, the operator uses targeting software to lock on to a moving vehicle; the software keeps the laser spot in place, an indirect way of engaging the target with its own risks if the system fails.

[…]

Hellfire does not tidily disintegrate the target as in a video game but leaves recognizable bodies and body parts around ground zero.

[…]

If fired in a straight line, Hellfire’s supersonic speed means the target will not hear it coming.

[…]

Hellfire may be precise, but it is not surgical. The twenty-pound high-explosive warhead can cause major “collateral damage,” killing innocent bystanders or building occupants when the target is a single terrorist.

Worse, the long time of flight means there is the risk of somebody wandering into the target area after the missile has been launched.

“Hellfire” supposedly comes from heliborne laser, fire-and-forget missile.

Having garbage-strewn subways that effectively serve as mobile homeless shelters is no way to run a public transit system

January 29th, 2024

It’s always jarring to come home to the US, Chris Arnade notes, often from much poorer countries, to find that our infrastructure is infinitely worse:

But it was what happened after I left the airport that convinced me that America, and especially NYC, is broken.

[…]

The train, to be fair, was on time. But it was filthy. The carriages were mostly empty, except for three or four homeless guys in each who were either sleeping or passed-out. The dozen or so of us who got on at the first stop chose our seats carefully, positioning ourselves close to each other, for safety, and as far as possible from the sprawled-out guys and their piles of trash and puddles of urine.

[…]

I thought about Sofia, where the subways and buses — and other public spaces and resources — are so much cleaner, safer, and smoother. Where workers simply wanting to get to their jobs don’t have to deal with navigating the mentally ill, addicted and desperate every day. For context, the GDP of Manhattan alone is about nine times that of the entire nation of Bulgaria. But NYC’s problems only seem to be getting worse, especially for those who have the least. I don’t have to take the subway; I have the cash for an Uber. But I try to see, and to understand a little, the world as most people see and understand the world.

[…]

Eventually, that morning, a guy covered in old vomit and carrying a cane, his trousers only just above his knees, got onto the subway train, and went up and down each carriage, hitting every sleeping or passed-out guy on the legs, yelling at them to move on, to give the rest of us some space. Everyone else pretended it wasn’t happening, hoping it wouldn’t go south, focusing instead on the floor or their phones.

[…]

But having garbage-strewn subways that effectively serve as mobile homeless shelters is no way to run a public transit system. It isn’t fair on the riders who don’t have the money to avoid the subway. It also isn’t fair on the homeless, who are being encouraged — or at least not discouraged — to hang out on crowded trains, maximising the chances that bad stuff will happen.

[…]

One of the forces that influenced LA authorities, though they won’t admit it, is homelessness. They built La Sombrita, rather than a proper bus shelter, for the same reason NYC is taking benches out of Port Authority: they don’t want people to sleep there. It’s something you see more and more in American cities: a locking down of public spaces in an attempt to deal with the growth of the homeless population. A removal of resources for the majority, because of concerns over “misuse” by less than 1% of residents.

[…]

To get big-brained about it, something like La Sombrita could only happen in a high-regulation/low-trust society like the US. If regulations massively limit both bottom-up and top-down solutions, and if those solutions are expected to protect against all sorts of bad behaviour, you end up building the least to mitigate the worst — building things the majority doesn’t want, or doesn’t find useful.

The high-regulation part of the US is usually couched in the language of safety, but it’s really about not allowing organic growth, which is messy — even though, people being people, it tends to result in things the majority really wants. Ecuador, by contrast, is a low-regulation (although low-trust) society: here, you get ad hoc, bottom-up solutions. If there is a bus stop in the middle of nowhere, without natural shade around it, riders rig an umbrella to a pole, or throw some old seats under a tree. In the US, such solutions would be dismantled within days.

But also, in places like Quito, bus stops attract street vendors, who come with umbrellas, making people feel safer by their very presence. LA has some of that, but it’s against the letter of the law, and vendors are constantly hassled with fines, or threats of shutdowns. My favourite taco place was closed down twice during my short stint in LA, for bureaucratic reasons. All this is to say that in Quito getting the bus is a much more pleasant experience than in LA — even though the latter city is roughly 1,000 times richer than Ecuador, and the latter has its own serious troubles.

Regulations themselves aren’t the problem, though. Germany, like much of northern Europe, is a high-regulation society, but it’s also high-trust, compared to the US. Here, nice and fully functional things are built without fear of misuse. For Americans, who have both a high-regulation and low-trust society, this is all rather depressing; it’s the combination that means we can’t have nice things.

Vacations will kill you

January 28th, 2024

Elon Musk by Walter IsaacsonMusk’s ouster as PayPal CEO allowed him to have his first weeklong holiday from work, Walter Isaacson explains (in his biography of Elon):

After getting back to Palo Alto in January 2001, Musk started feeling dizzy. His ears were ringing, and he had recurring waves of chills. So he went to the Stanford Hospital emergency room, where he started throwing up. A spinal tap showed he had a high white blood cell count, which led the doctors to diagnose him with viral meningitis. It’s generally not a severe disease, so the doctors rehydrated him and sent him home.

Over the next few days he felt progressively worse and at one point was so weak he could barely stand. So he called a taxi and went to a doctor. When she tried to take his pulse, it was barely perceptible. So she called an ambulance, which took him to Sequoia Hospital in Redwood City. A doctor who was an expert in infectious diseases happened to walk past Musk’s bed and realized that he had malaria, not meningitis. It turned out to be falciparum malaria, the most dangerous form, and they had caught it just in time. After symptoms become severe, as they had in Musk’s case, patients often have only a day or so before the parasite becomes untreatable. He was put into intensive care, where doctors stabbed a needle into his chest for intravenous infusions followed by massive doses of doxycycline.

The head of human resources at X.com went to visit Musk in the hospital and sort out his health insurance. “He was actually only hours from death,” the executive wrote in an email to Thiel and Levchin. “His doctor had treated two cases of falciparum malaria prior to treating Elon—both patients died.” Thiel remembers that he had a morbid conversation with the HR director after learning that Musk had taken out, on behalf of the company, a key-man life insurance policy for $ 100 million. “If he had died,” Thiel says, “all of our financial problems were going to be solved.”

[…]

Musk remained in intensive care for ten days, and he did not fully recover for five months. He took two lessons from his near-death experience: “Vacations will kill you. Also, South Africa. That place is still trying to destroy me.”

DJI might deplore the military use of its drones, but its new FlyCart 30 delivery drones looks perfect for delivering ordnance on target

January 27th, 2024

DJI, based in Shenzhen, China, dominate the consumer drone industry, David Hambling notes, with an estimated 70%+ of the global market:

In particular their Mavic range of affordable drones which fold up small enough to fit in a cargo pocket are outstanding platforms for rock-steady aerial videos or swooping shots of scenery. Mavics also make great battlefield scouts, and both sides in the conflict have used the drones heavily for reconnaissance and intelligence gathering, spotting hidden targets from miles away.

Small drones also multiply the effectiveness of artillery: by precisely directing rounds on target, drones make artillery five to ten times as effective. Everything from 155mm howitzers to 30mm automatic grenade launches now uses drone guidance, and they assist tanks to score indirect-fire kills from long range in a way that was previously impossible.

And of course, small drones are used as bombers. 3D printed bombing rigs arm small quadcopters with one or two grenades (typically Russian VOG-17 or American M433 “Golden eggs”) to drop into foxholes or trenches, or through hatches to destroy abandoned vehicles.

DJI deplores the military use of their drones. The company banned sales of their products in both Ukraine and Russia in April 2022 and has issued several strongly-worded statements, but these have been ignored.

But in Ukraine, ‘Mavik’ is now a generic term for any small drone, just as ‘Hoover’ and ‘Fridge’ were applied to any product of a certain type. In October 2023, Ukrainian Prime Minister Denys Shmyhal claimed his country bought 60% of the Mavic drones produced,DJI immediately denied this claim, and it does seem unlikely as DJI produce millions of drones and Ukraine’s purchases are likely to be in the hundreds of thousands, but it gives an idea of how significant they are.

DJI might deplore the military use of its drones, but its new FlyCart 30 delivery drones looks perfect for delivering ordnance on target:

With eight rotors on four arms, the FlyCart30 can haul up to 30 kilos/66 pounds a distance of ten miles, or carry lesser payloads greater distances. The control range is given as 13 miles, but extra features allow one-button transfer to a second operator.

Top speed is 45 mph, and the drone can fly in winds of up to 27 mph.

A mass of safety features include automatic radar and visual obstacle avoidance day or night, and a parachute which deploys if the engines fail, so the drone will always make a soft landing.

For deliveries, the FlyCart30 can carry a 70-liter cargo pod – a container the size of a suitcase – or, if there is no landing site, it can lower a payload on a winch while the drone hovers 60 feet above.

Like the Mavics, FlyCart30 folds up for easy transport. No international price has been announced, but last year the drone was advertised in China for just $17,000.

Ukraine’s heavy drones have recently taken on a new role as minelayers. Their engineers have developed a special fuse so a mine can be dropped from the air and only arm itself after it has handed. The drones can lay mines on roads or tracks from several miles away. They can also repair gaps in minefield where Russian engineers have started to clear a path.

[…]

The larger capacity also opens up the possibility of new types of attack drone. Several developers have already come up with stabilised weapon mounts for drones, such as the Baduga rifle system which comes with a high-powered rifle with 60 rounds. It can reliably hit a human-sized target with one shot from 200 meters. The Baduga system complete with a rifle and ammo weights less than 20 pounds.

In 2021, Nammo test-fired their M72 anti-armor rocket from a heavy drone. M72s weigh about eight pounds each, so FlyCart could carry a whole rack of them, benefitting from being able to attack the thin top armor.

The FlyCart could also act as a drone carrier, a mothership for multiple FPV attack drones. Both Ukraine and Russia have experimented with this concept, but an affordable heavy lift platform would make it far more feasible.
