It’s a very responsible job to shoot down drones when everyone is hiding

May 9th, 2024

There are plenty of electronic jammers on both the Russian and Ukrainian sides of the current war, but drone builders keep changing their operating frequencies and using jam-resistant radios, so the troops need shotguns:

Talking to Russian newspaper Lenta last month, retired Colonel Andrei Koshkin said that when electronic warfare fails, a shotgun can be the solution: “I have to say that even a simple shotgun that you go hunting with, which shoots a spray of shot, turns out to be more effective than a machine gun trying to shoot down a drone.”

Such weapons have been issued to some Russian units. Russian social media recently showed pictures of two soldiers credited with bringing down drones. The caption was illuminating though “The first is from the cover of the demining group, the second is from the protection of the Tor air defense system.” — in other words, both were assigned specifically to drone protection, so their role is to watch the skies, shotgun in hand, to protect their unit.

Both soldiers were armed with the 12-gauge Vepr-12 Molot shotgun, a semi-automatic weapon with a 5-round magazine.Other Russians are looking for improvised solutions to give a soldier the capability of a shotgun and assault rifle in one. For example, one video shows how an GP-25 underbarrel grenade launcher can be converted to fire a shotgun cartridge for drone defence.

The Vepr-12 is patterned after the original Kalashnikov rifle and built on the heavier RPK light machine gun receiver.

Another improvised Russian solution involves an adapter fitted to the end of the barrel of an AK-74 assault rifle to fire a single grapeshot round which the developers say had a high probability of stopping an FPV drone at 30 meters/ 100 feet range.

[…]

The Ukrainian soldier interviewed notes that shooting down drones is a full-time role which requires constant surveillance.

A piece in Armyinform in April describes a course given by an instructor who is a career soldier with long experience of hunting. He says that the men chosen for shotgun training were selected first from those with hunting experience and then from those with proven shooting skills. But he notes that the role also takes raw courage.

“It’s a very responsible job to shoot down drones when everyone is hiding,” says the instructor. “You have to have character.”

The instructor says that apart from practice at shooting fast-moving targets, there is also a strong safety aspect. In particular, shooters should not be tempted to try and pick up trophies.

“Don’t run after the drones to prove that you shot them down. Do not pick them up in your hands, do not pull the cat’s tail,” he says, noting the danger from unexploded or even booby-trapped drones. “Unfortunately, there have already been such cases.”

To form the sparse array antenna, the robots arrange themselves at roughly equal intervals

May 8th, 2024

Swarm Troopers by David HamblingSeveral drones working together can act as a single large radar dish, David Hambling explains (in Swarm Troopers), an arrangement known as a “sparse antenna array”:

The emissions from several drones are combined together into a single signal in a process called beamforming.

[…]

To form the sparse array antenna, the robots arrange themselves at roughly equal intervals, generally in a line or a circle. One robot acts as master and has software that takes information about the signal at each of the antennas — specifically the amplitude, phase, and delay — and combines this information to get an enhanced signal. There is little extra hardware needed as the system exists almost entirely in software, so any of the drones can be the master.

[…]

In a process known as nulling, the jammer signal is detected and located from its influence at different points, then completely cancelled out.

“I showed that we could completely ignore the effect of a jammer, positioned between the transmitter and receiver, that was twenty-three decibels above the desired transmitted signal,” says Okamoto.

Twenty-three decibels means the jammer is transmitting noise two hundred times as powerful as the source signal. It is like being able to hear a distant whisper while someone is bellowing in your ear.

[…]

In addition, Kocaman’s paper demonstrates how ten drones could act together and use “distributed beamforming,” like Kitts’ formation robots, to achieve more than a simple addition of their power would suggest. Kocaman calculates ten of these drones could jam a Russian Sam-2 Fan Song anti-aircraft radar, producing too much radio noise for the radar to “burn through.” This would render it helpless – the drones could broadcast the radar’s exact location with impunity, and even “lase” it with a designator, making the radar a sitting duck for an air strike.

[…]

A swarm that combined jammers with “flying IED” would be able to overwhelm a ship comparatively easily. If it attacked at night, even the last-ditch machine-guns would be lucky to score any hits.

[…]

Its ability to act as a giant antenna means it could carry out stealthy electronic eavesdropping over a wide area.

Two giant electron guns were to be mounted on either side of the aircraft

May 7th, 2024

Area 51 by Annie JacobsenThe phenomenally low radar cross section on the Oxcart (proto-SR-71), Annie Jacobsen explains (in Area 51), had to be lowered even further:

In a hangar not far from the radar range, Edward Lovick got to work on a one-eighth-scale model of the Oxcart. In what became known as Project Kempster-Lacroix, Lovick designed a system straight out of Star Trek or James Bond. “Two giant electron guns were to be mounted on either side of the aircraft,” Lovick recalls. Remarkably, the purpose of the guns would be “to shoot out a twenty-five-foot-wide ion cloud of highly charged particles in front of the plane as it flew over denied territory.” That gaseous cloud, Lovick determined, would further absorb radar waves coming up from radar tracking stations on the ground.

Using the small-scale model, the scientists were able to prove the scheme worked, which meant it was time to build a full-scale mock-up of Kempster-Lacroix. Testing the system out on a full-size aircraft, the scientists discovered that the radiation emitted by the electron guns would be too dangerous for the pilots. So a separate team of engineers designed an X-ray shield that the pilots could wear over their pressure suits while flying an Oxcart outfitted with Kempster-Lacroix. When one of the pilots made a test run, he determined that the thickness of the shield was far too cumbersome to wear while trying to fly an airplane at Mach 3. Then, while Lovick was working on a solution, the Air Force changed its mind. The Oxcart’s low observables were low enough, the Pentagon said. Project Kempster-Lacroix was abandoned.

SpaceX repeatedly proved that it could be nimbler than NASA

May 6th, 2024

Elon Musk by Walter Isaacson The Falcon 1 had failed three times before being successful, Walter Isaacson explains (in his biography of Elon), and the Falcon 9 was far bigger and more complex:

The chances for success were not helped when a storm rolled in and soaked the rocket. “Our antenna got wet,” Buzza recalls, “and we weren’t getting a good telemetry signal.” They lowered the rocket from the launchpad, and Musk came out with Buzza to inspect the damage. Bülent Altan, the goulash-cooking hero of Kwaj, climbed a ladder, looked at the antennas, and confirmed that they were too wet to work. A typical SpaceX fix was improvised: they fetched a hair dryer, and Altan waved it over the antennas until the moisture was gone. “You think it is good enough to fly tomorrow?” Musk asked him. Altan replied, “It should do the trick.” Musk stared at him silently for a while, assessing him and his answer, then said, “Okay, let’s do it.”

The next morning, the radio frequency checks were still not perfect. “It wasn’t the right sort of pattern,” Buzza says. So he told Musk there might be another delay. Musk looked at the data. As usual, he was willing to tolerate more risk than others. “It’s good enough,” he said. “Let’s launch.” Buzza assented. “The important thing with Elon,” he says, “is that if you told him the risks and showed him the engineering data, he would make a quick assessment and let the responsibility shift from your shoulders to his.”

[…]

The day before the planned December launch, a final pad inspection revealed two small cracks in the engine skirt of the rocket’s second stage. “Everyone at NASA assumed we’d be standing down from the launch for a few weeks,” says Garver. “The usual plan would have been to replace the entire engine.”

“What if we just cut the skirt?” Musk asked his team. “Like, literally cut around it?” In other words, why not just trim off a tiny bit of the bottom that had the two cracks? The shorter skirt would mean the engine would have slightly less thrust, one engineer warned, but Musk calculated that there would still be enough to do the mission. It took less than an hour to make the decision. Using a big pair of shears, the skirt was trimmed, and the rocket launched on its critical mission the next day, as planned. “NASA couldn’t do anything but accept SpaceX’s decisions and watch in disbelief,” Garver recalls.

[…]

SpaceX repeatedly proved that it could be nimbler than NASA. One example came during a mission to the Space Station in March 2013, when one of the valves in the engine of the Dragon capsule stuck shut. The SpaceX team started scrambling to figure out how to abort the mission and return the capsule safely before it crashed. Then they came up with a risky idea. Perhaps they could build up the pressure in front of the valve to a very high level. Then if they suddenly released the pressure, it might cause the valve to burp open. “It’s like the spacecraft equivalent of the Heimlich maneuver,” Musk later told the Washington Post’s Christian Davenport.

The top two NASA officials in the control room stood back and watched as the young SpaceX engineers hatched the plan. One of SpaceX’s software engineers churned out the code that would instruct the capsule to build up pressure, and they transmitted it as if it were a software update for a Tesla car.

Boom, pop. It worked.

It would be better to have one bad general than to have two good ones

May 5th, 2024

Napoleon by Andrew Roberts Even before the Directory had received the news of Napoleon’s victory at Lodi, Andrew Roberts explains (in Napoleon: A Life), they conceived a plan to try to force him to share the glory of the Italian campaign, as public adulation was starting to concentrate dangerously around him:

Ever since General Dumouriez’s treason in 1793, no government had wanted to accord too much power to any one general. When Napoleon requested that reinforcements of 15,000 men be taken from General Kellermann’s Army of the Alps, the Directory replied that the men could indeed be sent to Italy, but Kellermann must go with them and command of the Army of Italy would be split. Replying on May 14, four days after Lodi and the day before he captured Milan, Napoleon told Barras: ‘I will resign. Nature has given me a lot of character, along with some talents. I cannot be useful here unless I have your full confidence.’

[…]

‘I cannot serve willingly with a man who believes himself the first general of Europe, and furthermore I believe it would be better to have one bad general than to have two good ones. War, like government, is a matter of tact.’

[…]

‘Each to his own way of making war. General Kellermann has more experience and will do it better than myself; but both of us doing it together will do it extremely badly.’

As a last step, he fully covered the wound with the chewed leaves

May 4th, 2024

There is widespread evidence of such self-medication in non-human animals — whole-leaf swallowing, bitter-pith chewing, and fur rubbing in African great apes, orangutans, white handed gibbons, and several other species of monkeys — but there had been only one report of active wound treatment in non-human animals, namely in chimpanzees, until scientists spotted the active self-treatment of a facial wound with a biologically active plant by a male Sumatran orangutan:

We observed a male Sumatran orangutan (Pongo abelii) who sustained a facial wound. Three days after the injury he selectively ripped off leaves of a liana with the common name Akar Kuning (Fibraurea tinctoria), chewed on them, and then repeatedly applied the resulting juice onto the facial wound. As a last step, he fully covered the wound with the chewed leaves. Found in tropical forests of Southeast Asia, this and related liana species are known for their analgesic, antipyretic, and diuretic effects and are used in traditional medicine to treat various diseases, such as dysentery, diabetes, and malaria. Previous analyses of plant chemical compounds show the presence of furanoditerpenoids and protoberberine alkaloids, which are known to have antibacterial, anti-inflammatory, anti-fungal, antioxidant, and other biological activities of relevance to wound healing. This possibly innovative behavior presents the first systematically documented case of active wound treatment with a plant species know to contain biologically active substances by a wild animal and provides new insights into the origins of human wound care.

Orangutan Facial Wound Healing

Once a piece of art becomes mainstream, elites must distance themselves from it

May 3rd, 2024

Troubled by Rob Henderson Before his first year of college, Rob Henderson had never even been to a musical, he explains (in Troubled):

No one I knew from Red Bluff had ever been to one. But it seemed like everyone on campus had seen Hamilton, the acclaimed musical about the American founding father Alexander Hamilton. I looked up tickets: $400.

This was way beyond my budget. So in 2020, I was pleased to see that five years after Hamilton’s debut, it was available to view on Disney+. But suddenly, the musical was being denigrated by many of the same people who formerly enjoyed it, because it didn’t reflect the failings of American society in the eighteenth century. The creator of Hamilton, Lin-Manuel Miranda, even posted on Twitter that “All the criticisms are valid.” This reveals how social class works in America.

[…]

Once a piece of art becomes mainstream, elites must distance themselves from it and redirect their attention to something new, obscure, or difficult to obtain. The affluent relentlessly search for signals that distinguish them from the masses.

A former classmate recently told me that he didn’t enjoy Hamilton but never told anyone because everyone at Yale loved it. However, once the musical became unfashionable, he suddenly became open about his dislike of it.

No one buys books

May 2nd, 2024

Trial by Publisher’s LunchNo one buys books, Elle Griffin concludes:

In 2022, Penguin Random House wanted to buy Simon & Schuster. The two publishing houses made up 37 percent and 11 percent of the market share, according to the filing, and combined they would have condensed the Big Five publishing houses into the Big Four. But the government intervened and brought an antitrust case against Penguin to determine whether that would create a monopoly.

The judge ultimately ruled that the merger would create a monopoly and blocked the $2.2 billion purchase. But during the trial, the head of every major publishing house and literary agency got up on the stand to speak about the publishing industry and give numbers, giving us an eye-opening account of the industry from the inside. All of the transcripts from the trial were compiled into a book called The Trial. It took me a year to read, but I’ve finally summarized my findings and pulled out all the compelling highlights.

I think I can sum up what I’ve learned like this: The Big Five publishing houses spend most of their money on book advances for big celebrities like Britney Spears and franchise authors like James Patterson and this is the bulk of their business. They also sell a lot of Bibles, repeat best sellers like Lord of the Rings, and children’s books like The Very Hungry Caterpillar. These two market categories (celebrity books and repeat bestsellers from the backlist) make up the entirety of the publishing industry and even fund their vanity project: publishing all the rest of the books we think about when we think about book publishing (which make no money at all and typically sell less than 1,000 copies).

[…]

The DOJ’s lawyer collected data on 58,000 titles published in a year and discovered that 90 percent of them sold fewer than 2,000 copies and 50 percent sold less than a dozen copies.

[…]

They spent a lot of the trial talking about books that made an advance of more than $250,000—they called these “anticipated top-sellers.” According to Nicholas Hill, a partner at Bates White Economic Consulting, 2 percent of all titles earn an advance over $250,000.

[…]

Hill says titles that earn advances over $250,000 account for 70 percent of advance spending by publishing houses. At Penguin Random House, it’s even more. The bulk of their advance spending goes to deals worth $1 million or more, and there are about 200 of those deals a year. Of the roughly $370 million they say PRH accounts for, $200 million of that goes to advance deals worth $1 million or more.

[…]

Books by the Obamas sold so many copies they had to be removed from the charts as statistical anomalies.

[…]

Franchise authors are the other big category. Walsch says James Patterson and John Grisham get advances in the “many millions.” Putnam makes most of its money from repeat authors like John Sandford, Clive Cussler, Tom Clancy, Lisa Scottoline, and others.

[…]

Markus Dohle, CEO, Penguin Random House, says the top 4 percent of titles drive 60 percent of the profitability.

[…]

After the Judge denied the merger, Penguin went through a massive round of layoffs and Simon & Schuster was sold to a private equity company instead.

Skeins of geese gain a 70% range advantage by flying in formation

May 1st, 2024

Swarm Troopers by David HamblingSwarms of drones, David Hambling explains (in Swarm Troopers), might follow the model of flocks of geese to fly further together:

Large birds are often seen flying in skeins, V-shaped formations, with the birds spaced at regular intervals.

[…]

The tip of a wing, whether it is a goose or an Airbus 380, generates a whirlpool of air known as a tip vortex. This produces a downwash beneath the wings and an upwash just outside the wing. The vortex is actually a miniature tornado that may contain airspeeds of 100mph and may be about the same size of the span of the wing that produces it. The vortex from an airliner can be dangerous, as it is strong enough to flip a light aircraft right over. Close to the ground, the vortex from an aircraft taking off may persist for more than a minute.

[…]

By flying just to the side and behind, a following goose gets the benefit of the updraft provided by its companion. This gives it free lift, equivalent to flying downhill.

[…]

Naturalists’ estimate that skeins of geese gain a 70% range advantage by flying in formation rather than individually. A detailed aerodynamic study by the US Air Force Air Vehicles Directorate found that formations of nine aircraft could achieve an 80% increase in range over the distance they could fly alone.

One engine dead, the other generating enough power to propel an ocean liner

April 30th, 2024

Area 51 by Annie JacobsenTo the pilots of the still-experimental Oxcart, Annie Jacobsen explains (in Area 51), there was nothing scarier than an engine un-start:

To the engineers, there was nothing to explain the cause of it. Flying at a certain pitch, one of the two J-58 engines could inexplicably experience an airflow cutoff and go dead. At that speed, the inlets were swallowing ten thousand cubic feet of air each second. One engineer likened this to the equivalent of two million people inhaling at once; an un-start was like all those people suddenly cut short of air. During the ten seconds it took to correct the airflow problem—one engine dead, the other generating enough power to propel an ocean liner—a violent yawing would occur as the aircraft twisted on a vertical axis. This caused a pilot to get slammed across the cockpit while desperately trying to restart the dead engine. The fear was that the pilot could get knocked unconscious, which would mean the end of the pilot, and the end of the airplane.

[…]

Once, a pilot flying over semirural West Virginia had to restart an engine at thirty thousand feet. The resulting sonic boom shattered a chimney inside a factory on the ground, and two men working there were crushed to death.

[…]

Collins pushed the aircraft through Mach 2.8. In another forty-five seconds he would be out of the danger zone. Nearing eighty-five thousand feet, the inevitable tiny black dots began to appear on the aircraft windshield, sporadic at first, like the first drops of summer rain. Only a few months earlier, scientists at Area 51 had been baffled by those black dots. They worried it was some kind of high-atmosphere corrosion until the mystery was solved in the lab. It turned out the black spots were dead bugs that were cycling around in the upper atmosphere, blasted into the jet stream by the world’s two superpowers’ rally of thermonuclear bombs. The bugs were killed in the bombs’ blasts and sent aloft to ninety thousand feet in the ensuing mushroom clouds where they gained orbit.

[…]

In a critical instant, the airplane banged and yawed so dramatically it was as if the airplane’s tail were trying to catch its nose. Collins’s body was flung forward in his harness. His plastic flight helmet crashed against the cockpit glass, denting the helmet and nearly knocking him unconscious. As the airplane slid across the atmosphere, Collins steeled himself and restarted the engine. The aircraft’s second engine kicked back into motion almost as quickly as it had stopped.

[…]

A hand-cranked calculator and a metal slide rule sat on Rich’s desk. Park set his flight helmet down—it had its own crack, similar to Collins’s—and pointed to it. “Fix it,” Park said. “And I mean the un-start problem, not my helmet. Time to suit up, Ben. Time for you to see how it feels.” The pilots figured that the only way to get Ben Rich to understand just how unacceptable this un-start business was would be to have Rich experience the nightmare scenario himself, and there just happened to be a two-seater version of the Oxcart on base. The Air Force was currently testing its drone-carrying version of the Oxcart, the M-21/D-21, in the skies over Groom Lake, and the pilots had seen the two-seater going in and out of the hangar all week. Park told Ben Rich the time had come for him to take a Mach 3 ride.

In a burst of what he would later describe as “a crazy moment of weakness,” Ben Rich agreed. Rich was a self-described Jewish nerd. Totally unathletic, he was a kid who never made the high school baseball team. Before joining Skunk Works, Ben Rich had only one claim to fame: being awarded a patent for designing a nickel-chromium heating system that prevented a pilot’s penis from freezing to his urine elimination pipe. He was a design wizard, not an airplane cowboy. He’d never come close to flying supersonic before, and he had absolutely no desire to go that fast. But he was chief engineer for Skunk Works, so fixing the un-start problem was his job. “I’ll do it,” Ben Rich said.

[…]

Rich passed the physical and a few early stress tests but when he got to the pressure-chamber test—the one that simulated ejection at fifty thousand feet—things did not go as the engineer had planned. The moment the chamber door closed behind Ben Rich, he panicked. “I was sucking oxygen like a marathon runner and screaming, ‘Get me out of here!’” Rich later recalled. Without ever getting close to simulating what it was like to fly at Mach 3, let alone experiencing an un-start at that speed, Ben Rich admitted in his memoir that he had still nearly dropped dead from fright.

But the point was made. Rich dedicated all his efforts to fixing the un-start problem.

[…]

Rich invented an electronic control that made sure that when one engine experienced an un-start, the second engine dropped its power as well. The control switch would then restart both engines at the same time. After the new fix, pilots were notified of the un-start by a loud buzzing noise in the cockpit. And as far as nearly getting knocked unconscious at 2,000 miles per hour, Oxcart pilots could cross that off their lists of concerns.

Decades of cost-plus contracts had made aerospace flabby

April 29th, 2024

Elon Musk by Walter IsaacsonThe Falcon 1’s successor was supposed to have five more powerful engines, Walter Isaacson explains (in his biography of Elon), and thus be called the Falcon 5:

But Tom Mueller worried that it would take too long to build a new engine, and he persuaded Musk to accept a revised idea: a rocket with nine of the original Merlin engines. Thus was born the Falcon 9, a rocket that would become the workhorse of SpaceX for more than a decade. At 157 feet, it was more than twice as tall as the Falcon 1, ten times more powerful, and twelve times heavier.

The new rocket would also need a more convenient launch pad that the one on Kwajalein:

SpaceX made a deal to use part of the Kennedy Space Center at Cape Canaveral, which has close to seven hundred buildings, pads, and launch complexes spread out over 144,000 acres on Florida’s Atlantic coast. SpaceX leased Launchpad 40, which since the 1960s had been used for the Air Force’s Titan rocket launches.

[…]

Regularly prodded by Musk, Mosdell rebuilt the area in SpaceX’s typical scrappy way, literally. He and his boss, Tim Buzza, scavenged for components that could be cheaply repurposed. Buzza was driving down a road at Cape Canaveral and saw an old liquid oxygen tank. “I asked the general if we could buy it,” he says, “and we got a $1.5 million pressure vessel for scrap. It’s still at Pad 40.”

Musk also saved money by questioning requirements. When he asked his team why it would cost $2 million to build a pair of cranes to lift the Falcon 9, he was shown all the safety regulations imposed by the Air Force. Most were obsolete, and Mosdell was able to convince the military to revise them. The cranes ended up costing $300,000.

Decades of cost-plus contracts had made aerospace flabby. A valve in a rocket would cost thirty times more than a similar valve in a car, so Musk constantly pressed his team to source components from non-aerospace companies. The latches used by NASA in the Space Station cost $1,500 each. A SpaceX engineer was able to modify a latch used in a bathroom stall and create a locking mechanism that cost $30. When an engineer came to Musk’s cubicle and told him that the air-cooling system for the payload bay of the Falcon 9 would cost more than $3 million, he shouted over to Gwynne Shotwell in her adjacent cubicle to ask what an air-conditioning system for a house cost. About $6,000, she said. So the SpaceX team bought some commercial air-conditioning units and modified their pumps so they could work atop the rocket.

When Mosdell worked for Lockheed and Boeing, he rebuilt a launchpad complex at the Cape for the Delta IV rocket. The similar one he built for the Falcon 9 cost one-tenth as much.

The Emperor requests, general, that on receipt of this order you will…

April 28th, 2024

Napoleon by Andrew RobertsNapoleon was the first commander to employ a chief-of-staff in its modern sense, Andrew Roberts explains (in Napoleon: A Life), and he couldn’t have chosen a more efficient one:

With a memory second only to his own, Berthier could keep his head clear after twelve hours of taking dictation; on one occasion in 1809 he was summoned no fewer than seventeen times in a single night. The Archives Nationales, Bibliothèque Nationale and the Archives of the Grande Armée at Vincennes teem with orders in the neat secretarial script and short concise sentences that Berthier used to communicate with his colleagues, conveying Napoleon’s wishes in polite but firm terms, invariably starting ‘The Emperor requests, general, that on receipt of this order you will…’

[…]

His special ability, amounting to something approaching genius, was to translate the sketchiest of general commands into precise written orders for every demi-brigade. Staff-work was rarely less than superbly efficient. To process Napoleon’s rapid-fire orders required a skilled team of clerks, orderlies, adjutants and aides-de-camp, and a very advanced filing system, and he often worked through the night. On one of the few occasions when Napoleon spotted an error in the troop numbers for a demi-brigade, he wrote to correct Berthier, adding: ‘I read these position statements with as much relish as a novel.’

The poor reap what the luxury belief class sows

April 26th, 2024

Troubled by Rob HendersonGradually, Rob Henderson developed the concept of “luxury beliefs,” he explains (in Troubled), which are ideas and opinions that confer status on the upper class at very little cost, while often inflicting costs on the lower classes:

Research has found that parental educational attainment is the most important objective indicator of social class. This is because, compared with parental income, parental education is a more powerful predictor of a child’s future lifestyle, tastes, and opinions. In 2021, more than 80 percent of Ivy League students had parents with college degrees.

Paul Fussell — the social critic and author of Class — wrote that manners, tastes, opinions, and conversational style are just as important for upper-class membership as money or credentials, and that to fulfill these requirements, you have to be immersed in affluence from birth. Likewise, the twentieth-century French sociologist Pierre Bourdieu stated that a “triadic structure” of schooling, language, and taste was necessary to be accepted among the upper class. Bourdieu described the mastery of this triad as “ease.” When you grow up in a social class, you come to embody it. You represent its tastes and values so deeply that you exhibit “ease” within it.

[…]

Consistent with this, in 2021 the Pew Research Center found that among households headed by a college graduate, the median wealth of those who have a parent with at least a bachelor’s degree was nearly $100,000 greater than those who don’t have college-educated parents. This bonus of being a “continuing-generation” (as opposed to a “first-generation”) college graduate has been termed the “parent premium.”

[…]

For example, a former classmate at Yale told me “monogamy is kind of outdated” and not good for society. I asked her what her background is and if she planned to marry. She said she came from an affluent family, was raised by both of her parents, and that, yes, she personally intended to have a monogamous marriage—but quickly added that marriage shouldn’t have to be for everyone.

[…]

Some would, for instance, tell me about the admiration they had for the military, or how trade schools were just as respectable as college, or how college was not necessary to be successful. But when I asked them if they would encourage their own children to enlist or become a plumber or an electrician rather than apply to college, they would demur or change the subject.

Later, I would connect my observations to stories I read about tech tycoons, another affluent group, who encourage people to use addictive devices, while simultaneously enforcing rigid rules at home about technology use. For example, Steve Jobs prohibited his children from using iPads. Parents in Silicon Valley reportedly tell their nannies to closely monitor how much their children use their smartphones. Chip and Joanna Gaines are well-known home improvement TV personalities who have their own television network. They don’t allow their children to watch TV and don’t own a television. Don’t get high on your own supply, I guess.

[…]

The affluent have decoupled social status from goods and reattached it to beliefs.

Human beings become more preoccupied with social status once our physical needs are met. In fact, research has revealed that sociometric status (respect and admiration from peers) is more important for well-being than socioeconomic status. Furthermore, studies have shown that negative social judgment is associated with a spike in cortisol (a hormone linked to stress) that is three times higher than in nonsocial stressful situations. We feel pressure to build and maintain social status, and fear losing it.

It seems reasonable to think that the most downtrodden might be most interested in obtaining status and money. But this is not the case.

[…]

The French sociologist Émile Durkheim understood this when he wrote, “The more one has, the more one wants, since satisfactions received only stimulate instead of filling needs.”

[…]

A psychology study in 2020 revealed that “Upper-class individuals cared more about status and valued it more highly than working-class individuals.… Furthermore, compared with lower-status individuals, high-status individuals were more likely to engage in behavior aimed at protecting or enhancing their status.”

[…]

You might think that, for example, rich students at elite universities would be happy because their parents are in the top 1 percent of income earners, and that statistically they will soon join their parents in this elite guild. But remember, they’re surrounded by other members of the 1 percent. For many elite college students, their social circle consists of baby millionaires, which often instills a sense of insecurity and an anxiety to preserve and maintain their positions against such rarefied competitors.

Thorstein Veblen’s famous “leisure class” has evolved into the “luxury belief class.” Veblen, an economist and sociologist, made his observations about social class in the late nineteenth century. He compiled his observations in his classic 1899 book, The Theory of the Leisure Class. A key idea is that because we can’t be certain of the financial standing of other people, a good way to size up their means is to see whether they can afford to waste money on goods and leisure. This explains why status symbols are so often difficult to obtain and costly to purchase. In Veblen’s day, people exhibited their status with delicate and restrictive clothing like tuxedos, top hats, and evening gowns, or by partaking in time-consuming activities like golf or beagling. Such goods and leisurely activities could only be purchased or performed by those who did not live the life of a manual laborer and could spend time learning something with no practical utility. Veblen even goes so far as to say, “The chief use of servants is the evidence they afford of the master’s ability to pay.” For Veblen, even butlers were status symbols.

[…]

As NYU professor Scott Galloway said in an interview in 2020, “The strongest brand in the world is not Apple or Mercedes-Benz or Coca-Cola. The strongest brands are MIT, Oxford, and Stanford. Academics and administrators at the top universities have decided over the last thirty years that we’re no longer public servants; we’re luxury goods.”

Your typical working-class American could not tell you what heteronormative or cisgender means. But if you visit an elite college, you’ll find plenty of affluent people who will eagerly explain them to you. When someone uses the phrase cultural appropriation, what they are really saying is, “I was educated at a top college.” Consider the Veblen quote, “Refined tastes, manners, habits of life are a useful evidence of gentility, because good breeding requires time, application and expense, and can therefore not be compassed by those whose time and energy are taken up with work.” Only the affluent can afford to learn strange vocabulary, because ordinary people have real problems to worry about.

The chief purpose of luxury beliefs is to indicate the believer’s social class and education. When an affluent person expresses support for defunding the police, drug legalization, open borders, looting, or permissive sexual norms, or uses terms like white privilege, they are engaging in a status display. They are trying to tell you, “I am a member of the upper class.”

Focusing on “representation” rather than helping the downtrodden is another luxury belief. Many of the protesters on campus urged for more individuals from historically mistreated groups to be represented among students and faculty, among elite internships and occupations, and in influential positions in society at large. I thought of this as “trickle-down meritocracy.” The idea seemed to be that the best way to help struggling communities is to pluck representatives out and put them into positions of power. As long as the ruling class has a few members from these communities, then somehow the advantages they accrue will “trickle down” to their communities. Thus far, there doesn’t seem to be evidence that this works.

Upon completing their education, most of these graduates do not return to their old neighborhoods. Instead, they relocate to a handful of cities where they live alongside their highly educated peers, eroding the bonds of solidarity they had with those they left behind.

White privilege is the luxury belief that took me the longest to understand, because I grew up around a lot of poor white people. Affluent white college graduates seem to be the most enthusiastic about the idea of white privilege, yet they are the least likely to incur any costs for promoting that belief. Rather, they raise their social standing by talking about their privilege. In other words, upper-class white people gain status by talking about their high status. When policies are implemented to combat white privilege, it won’t be Yale graduates who are harmed. Poor white people will bear the brunt.

The upper class promotes abolishing the police or decriminalizing drugs or white privilege because it advances their social standing, not least because they know that the adoption of those policies will cost them less than others. The logic is akin to conspicuous consumption: if you’re a student who has a large subsidy from your parents and I do not, you can afford to waste $900 and I can’t, so wearing a Canada Goose jacket is a good way of advertising your superior wealth and status. Proposing policies that will cost you as a member of the upper class less than they would cost me serves the same function. Advocating for sexual promiscuity, drug experimentation, or abolishing the police are good ways of advertising your membership of the elite because, thanks to your wealth and social connections, they will cost you less than me.

Reflecting on my experiences with alcohol, if all drugs had been legal and easily accessible when I was fifteen, you wouldn’t be reading this book. My birth mom was able to get drugs, and it had a detrimental effect on both of our lives. That’s something people don’t think about: drugs don’t just affect the user, they affect helpless children, too. All my foster siblings’ parents were addicts, or had a mental health condition, often triggered by drug use. But the luxury belief class doesn’t think about that because such consequences seldom interrupt their lives. And even if they did, they are in a far better position to withstand such difficulties. A well-heeled student at an elite university can experiment with cocaine and will, in all likelihood, be fine. A kid from a dysfunctional home with absentee parents will often take that first hit of meth to self-destruction. This is perhaps why a 2019 survey found that less than half of Americans without a college degree want to legalize drugs, but more than 60 percent of Americans with a bachelor’s degree or higher are in favor of drug legalization.

[…]

Similarly, a 2020 survey found that the richest Americans showed the strongest support for defunding the police, while the poorest Americans reported the lowest support. Throughout the remainder of that year and into 2021, murder rates throughout the US soared as a result of defunding policies, officers retiring early or quitting, and police departments struggling to recruit new members after the luxury belief class cultivated an environment of loathing toward law enforcement.

The luxury belief class appears to sympathize more with criminals than their victims. It’s true that most criminals come from poor backgrounds. But it’s also true that their victims are mostly poor. And the perpetrators tend to be young men, and their targets are often poor women or the elderly. Moreover, because there are many times more victims than there are criminals, to not stop criminals is to victimize the poor.

[…]

The poor reap what the luxury belief class sows.

Consider that compared to Americans who earn more than $75,000 a year, the poorest Americans are seven times more likely to be victims of robbery, seven times more likely to be victims of aggravated assault, and twenty times more likely to be victims of sexual assault.

Unfortunately, like fashion trends that debut on the runway and make it into JCPenney three years later, the luxury beliefs of the upper class often trickle down and are adopted by people lower on the food chain, which means many of these beliefs end up causing social harm. Take polyamory, which involves open relationships where people have multiple partners at the same time. A student at a top university once explained to me that when he set the radius on his dating apps to five miles, about half of the women, mostly other students, said they were “polyamorous” in their bios. Then, when he extended the radius to fifteen miles to include the rest of the city and its outskirts, about half of the women were single mothers. Polyamory is the latest expression of sexual freedom championed by the affluent.

[…]

Most personal to me is the luxury belief that family is unimportant or that children are equally likely to thrive in all family structures. In 1960, the percentage of American children living with both biological parents was identical for affluent and working-class families — 95 percent. By 2005, 85 percent of affluent families were still intact, but for working-class families the figure had plummeted to 30 percent. The Harvard political scientist Robert Putnam at a 2017 Senate hearing stated, “Rich kids and poor kids now grow up in separate Americas.… Growing up with two parents is now unusual in the working class, while two-parent families are normal and becoming more common among the upper middle class.” Affluent people, particularly in the 1960s, championed sexual freedom. Loose sexual norms caught on for the rest of society. The upper class, though, still had intact families. Generally speaking, they experimented in college and then settled down later. The families of the lower classes fell apart.

[…]

In 2006, more than half of American adults without a college degree believed it was “very important” that couples with children should be married. Fast-forward to 2020, and this number has plummeted to 31 percent. Among college graduates, only 25 percent think couples should be married before having kids. Their actions, though, contradict their luxury beliefs: the vast majority of American college graduates who have children are married. Despite their behavior suggesting otherwise, affluent people are the most likely to say marriage is unimportant. Gradually, their message has spread.

I’ve also heard graduates of top universities say marriage is “just a piece of paper.” People shouldn’t have to prove their commitment to their spouse with a document, they tell me. I have never heard them ridicule a college degree as “just a piece of paper.” Many affluent people belittle marriage, but not college, because they view a degree as critical for their social positions.

Hopefully, they’ll even start hearing the Jaws theme in their head if they suspect one is about

Anduril Australia’s Ghost Shark “extra-large” underwater autonomous sub has been delivered one year early and on budget. The official name was revealed a couple years ago:

In a nod to the Ghost Bat unmanned aircraft developed by Boeing Australia for the Royal Australian Air Force, the new autonomous and unmanned weapon will be known as Ghost Shark.

On top of showing off the prototype, to be used for testing and concept definition, Rear Adm. Peter Quinn made clear the still-to-come larger, schoolbus-sized system may carry warheads.

“Due to their range, stealth and persistence Ghost Shark will be able to operate throughout the Indo-Pacific. Due to its modular and multi-role nature, our adversaries will need to assume that their every move in the maritime domain is subject to our surveillance and that every XL-UV (drone) is capable of deploying a wide range of effects — including lethal ones,” Quinn told a small audience of government officials, officers and journalists. “Once your potential adversaries understand what a Ghost Shark is — not that we’re going to give them any specifics at all — we expect they will generate doubt and uncertainty.”

Then he delivered the best line of the day, greeted with appreciative laughter from the crowd: “Hopefully, they’ll even start hearing the Jaws theme in their head if they suspect one is about.”

This zig-zagging slows it down

Swarm Troopers by David HamblingSwarms of drones, David Hambling explains (in Swarm Troopers), might follow the model of pack-hunters like wolves:

Wolves are unusual among carnivores in that, in some areas, they prey largely on animals larger than themselves. Not only are moose and bison several times bigger than wolves, they are also faster. But a pack of wolves can bring down a large prey animal by working in a pack and using a set of heuristics — simple hunting tactics from a combination of instinct and experience.

[…]

During the approach, each wolf moved towards the prey until it reached a certain distance; it then moved away from any other wolves that were the same distance. The net effect was that the wolf pack spread out and enveloped the prey. If the prey tries to circle around, the pack keeps homing on it, and in simulations the prey often ended up running towards one of the pursuers and was “ambushed” by it. Even though the prey may be faster than the wolves, it keeps turning to get away from the nearest wolf. This zig-zagging slows it down so that another member of the pack travelling in a straight line can catch it.

Harris hawks provide another model:

Harris hawks are medium-sized hawks native to the Americas, found from the southwestern US to Chile and Argentina, which use a variety of approaches to attack prey. They are among the few birds of prey that work cooperatively, often in family groups of four to six birds. The most common tactic is a simultaneous attack with multiple Harris hawks diving in from different directions; a rabbit or other prey may dodge the first hawk or two before getting picked up by the third or fourth.

When prey goes to ground, the hawks switch tactics. The birds perch around the cover where their target has hidden, surrounding the prey, and then take turns attempting to penetrate the cover. As soon as the prey is flushed out, the surrounding birds swoop in and take it.

Finally, Harris hawks also carry out “relay attacks” in which multiple birds swoop down one after the other, each chasing the prey for a short distance. As it escapes one hawk, the next one in the flock takes over. Researchers have recorded up to twenty swoops in one chase over half a mile before the exhausted prey was finally taken.
