Mark Zuckerberg, Let Me Pay for Facebook - NYTimes.com - 0 views

  • 93 percent of the public believes that “being in control of who can get information about them is important,” and yet the amount of information we generate online has exploded and we seldom know where it all goes.
  • the pop-up and the ad-financed business model. The former is annoying but it’s the latter that is helping destroy the fabric of a rich, pluralistic Internet.
  • Facebook makes about 20 cents per user per month in profit. This is a pitiful sum, especially since the average user spends an impressive 20 hours on Facebook every month, according to the company. This paltry profit margin drives the business model: Internet ads are basically worthless unless they are hyper-targeted based on tracking and extensive profiling of users. This is a bad bargain, especially since two-thirds of American adults don’t want ads that target them based on that tracking and analysis of personal behavior.

  • This way of doing business rewards huge Internet platforms, since ads that are worth so little can support only companies with hundreds of millions of users.
  • Ad-based businesses distort our online interactions. People flock to Internet platforms because they help us connect with one another or the world’s bounty of information — a crucial, valuable function. Yet ad-based financing means that the companies have an interest in manipulating our attention on behalf of advertisers, instead of letting us connect as we wish.
  • Many users think their feed shows everything that their friends post. It doesn’t. Facebook runs its billion-plus users’ newsfeed by a proprietary, ever-changing algorithm that decides what we see. If Facebook didn’t have to control the feed to keep us on the site longer and to inject ads into our stream, it could instead offer us control over this algorithm.
  • Many nonprofits and civic groups that were initially thrilled about their success in using Facebook to reach people are now despondent as their entries are less and less likely to reach people who “liked” their posts unless they pay Facebook to help boost their updates.
  • What to do? It’s simple: Internet sites should allow their users to be the customers. I would, as I bet many others would, happily pay more than 20 cents per month for a Facebook or a Google that did not track me, upgraded its encryption and treated me as a customer whose preferences and privacy matter.
  • Many people say that no significant number of users will ever pay directly for Internet services. But that is because we are misled by the mantra that these services are free. With growing awareness of the privacy cost of ads, this may well change. Millions of people pay for Netflix despite the fact that pirated copies of many movies are available free. We eventually pay for ads, anyway, as that cost is baked into products we purchase
  • A seamless, secure micropayment system that spreads a few pennies at a time as we browse a social network, up to a preset monthly limit, would alter the whole landscape for the better.
  • we’re not starting from scratch. Micropayment systems that would allow users to spend a few cents here and there, not be so easily tracked by all the Big Brothers, and even allow personalization were developed in the early days of the Internet. Big banks and large Internet platforms didn’t show much interest in this micropayment path, which would limit their surveillance abilities. We can revive it.
  • If even a quarter of Facebook’s 1.5 billion users were willing to pay $1 per month in return for not being tracked or targeted based on their data, that would yield more than $4 billion per year — surely a number worth considering.
  • Mr. Zuckerberg has reportedly spent more than $30 million to buy the homes around his in Palo Alto, Calif., and more than $100 million for a secluded parcel of land in Hawaii. He knows privacy is worth paying for. So he should let us pay a few dollars to protect ours.

The Fortnightly Review › Death to the Reading Class. - 0 views

  • most people don’t want to read and, therefore, don’t read. The evidence on this score is clear: the average American reads for about fifteen minutes a day and almost never reads a book for pleasure.
  • we have tried to solve the reading “problem” by removing the most obvious impediments to reading: we taught everyone to read; we printed millions upon millions of books; and we made those books practically free in libraries. And so the barriers fell: now nearly everyone in the developed world is literate, there is plenty to read, and reading material is dirt cheap. But still people don’t read. Why? The obvious answer—though one that is difficult for us to admit—is that most people don’t like to read.
  • Humans achieved their modern form about 180,000 years ago; for 175,000 of those years they never wrote or read anything. About 40,000 years ago, humans began to make symbols,

  • Most people successfully avoided reading until about 300 years ago. It was about then that Western European priests and princes decided that everyone should be taught to read. These literacy-loving types tried various schemes to make common folks literate; the most effective of these, however, was naked coercion. By the nineteenth century, churches and states all over Europe and North America were forcing parents to send their kids to school to learn to read
  • So it happened that by the early twentieth century most people in Western Europe and North America could read. They had no choice in the matter. They still don’t.
  • Why don’t most people like to read? The answer is surprisingly simple: humans weren’t evolved to read. Note that we have no reading organs: our eyes and brains were made for watching, not for decoding tiny symbols on mulch sheets. To prepare our eyes and brains for reading, we must rewire them. This process takes years of hard work to accomplish, and some people never accomplish it all. Moreover, even after you’ve learned to read, you probably won’t find reading to be very much fun. It consumes all of your attention, requires active thought, and makes your eyes hurt. For most people, then, reading is naturally hard and, therefore, something to be avoided if at all possible.
  • we have misidentified the “problem” facing us: it is not the much-bemoaned reading gap, but rather a seldom-mentioned knowledge gap. Though it is immodest to say, we readers genuinely know more than those who do not read. Thus we are usually able to make better-informed decisions than non-readers can.
  • If we lived in an aristocracy of readers, this maldistribution of knowledge might be acceptable. But we don’t; rather, we live in a democracy (if we are lucky). In a democracy, the people – readers and non-readers alike – decide. Thus we would like all citizens to be knowledgeable so that they can make well-informed decisions about our common affairs. This has been a central goal of the Reading Class since the literacy-loving Enlightenment.
  • If we in the Reading Class want to teach the the reading-averse public more effectively than we have in the past, we must rid ourselves of our reading fetish and admit that we’ve been falling down on the job. Once we take this painful step, then a number of interesting options for closing the knowledge gap become available. The most promising of these options is using audio and video to share what we know with the public at large.
  • We have to laboriously learn to read, but we are born with the ability to watch and listen. We don’t find reading terribly pleasant, but we do find watching and listening generally enjoyable.
  • The results of this “natural experiment” are in: people would much rather watch/listen than read. This is why Americans sit in front of the television for three hours a day, while they read for only a tiny fraction of that time.
  • Our task, then, is to give them something serious to watch and listen to, something that conveys the richness and complexity of our written work in pictures and sounds. The good news is that we can easily do this.
  • Today any lecturer can produce and distribute high quality audio and video programs. Most scholars have the equipment on their desks (that is, a PC). The software is dead simple and inexpensive. And the shows themselves can be distributed the world over on the Internet for almost nothing.
  • I’ve done it. Here are two examples. The first is New Books in History, an author-interview podcast featuring historians with new books. Aside from the computer, the total hardware and software start-up costs were roughly $300. It took me no time to learn the software thanks to some handy on-line tutorials available on Lynda.com. Today New Books in History has a large international audience.
  • The “new books” podcasts are not about serious books; they are about the ideas trapped in those serious, and seriously un-read, books. Books imprison ideas; the “new books” podcasts set them free.)

Conservative Delusions About Inflation - NYTimes.com - 0 views

  • the stark partisan divide over issues that should be simply factual, like whether the planet is warming or evolution happened.
  • The problem, in other words, isn’t ignorance; it’s wishful thinking. Confronted with a conflict between evidence and what they want to believe for political and/or religious reasons, many people reject the evidence. And knowing more about the issues widens the divide, because the well informed have a clearer view of which evidence they need to reject to sustain their belief system.
  • the similar state of affairs when it comes to economics, monetary economics in particular.
  • ...7 more annotations...
  • Above all, there were many dire warnings about the evils of “printing money.” For example, in May 2009 an editorial in The Wall Street Journal warned that both interest rates and inflation were set to surge “now that Congress and the Federal Reserve have flooded the world with dollars.” In 2010 a virtual Who’s Who of conservative economists and pundits sent an open letter to Ben Bernanke warning that his policies risked “currency debasement and inflation.”
  • Although the Fed continued on its expansionary course — its balance sheet has grown to more than $4 trillion, up fivefold since the start of the crisis — inflation stayed low. For the most part, the funds the Fed injected into the economy simply piled up either in bank reserves or in cash holdings by individuals — which was exactly what economists on the other side of the divide had predicted would happen.
  • In fact, hardly any of the people who predicted runaway inflation have acknowledged that they were wrong, and that the error suggests something amiss with their approach. Some have offered lame excuses; some, following in the footsteps of climate-change deniers, have gone down the conspiracy-theory rabbit hole, claiming that we really do have soaring inflation, but the government is lying about the numbers
  • Mainly, though, the currency-debasement crowd just keeps repeating the same lines, ignoring its utter failure in prognostication.
  • Isn’t the question of how to manage the money supply a technical issue, not a matter of theological doctrine?
  • Well, it turns out that money is indeed a kind of theological issue. Many on the right are hostile to any kind of government activism, seeing it as the thin edge of the wedge — if you concede that the Fed can sometimes help the economy by creating “fiat money,” the next thing you know liberals will confiscate your wealth and give it to the 47 percent.
  • if you look at the internal dynamics of the Republican Party, it’s obvious that the currency-debasement, return-to-gold faction has been gaining strength even as its predictions keep failing.

Bones discovered in an island cave may be an early human species - The Washington Post - 0 views

  • Piper, Mijares and their team published a description of the foot bone in 2010. They knew it was the oldest human remain in the Philippines, dated to 67,000 years ago, based on the amount of the radioactive element uranium in the fossil
  • Mijares returned to Callao Cave and uncovered more remains in 2011 and 2015. All told, the scientists pulled a dozen fossilized parts from the cave — teeth, a thigh bone, finger bones and foot bones, representing three individuals. Attempts to extract DNA from the remains were unsuccessful.
  • The body parts are diminutive, suggesting Homo luzonensis grew no more than four feet tall. Its molars have modern shapes. The way its leg muscle attached to its thigh bone is “distinctively human,”

  • The bones in its hands and feet are curved, “spitting images” of the toes and finger bones that belonged to the ancient Australopithecus, Piper said. These hominids, such as the 3 million-year-old Australopithecus afarensis Lucy, had digits well-suited for climbing.
  • This species lived at the same time as humans with modern anatomy, who first appeared in the fossil record 200,000 years ago (or perhaps as long as 350,000 years ago). ″We continue to realize that few thousands of years back in time, H. sapiens was definitely not alone on Earth,”
  • Though these fossils are the oldest in the Philippines, evidence for habitation is even older; 700,000 years ago, ancient butchers on Luzon carved up a rhinoceros with stone tools. Which species did the butchering is unknown.
  • A few “mammal species you find on Luzon appear to have come from the mainland,” Piper said. The Asian continent is 400 or more miles away through the Luzon strait. But in the Middle Pleistocene, when glacial sheets locked up vast amounts of water, sea levels dropped by as much as 400 feet, Piper said.
  • “I would just say that when humans could see land or they could smell it or they knew the signs, that birds were coming from it, they sought it out,” he said. “That’s not a Homo sapiens trait. It’s something our ancestors and extinct relatives had.”
  • The cartoon version of evolution, in which a hunched ape becomes a tall and jaunty biped, suggests a journey with a destination. The reality is messier,
  • An island’s confines can rapidly spark evolutionary change; Charles Darwin saw this in finches’ beaks.
  • “Isolation plays games,” Potts said. Homo floresiensis showed anthropologists that an island could be an “odd little laboratory of human evolution,” he said. These bones reinforce that lesson.
  • “It’s beginning to look like the evolutionary process is really fluid,” Potts said. “And it’s surprising that it is so fluid where each species of Homo may actually be a history or a record.” The result is a fusion of the modern and ancient: molars that could be yours alongside toes with millions-year-old curves.
  • Fifteen years ago, Hawks said, anthropologists chalked up the worldwide success of Homo sapiens to our modern anatomy. These new discoveries, in far-flung corners, suggest exceptionalism is not built into our brains or skeletons.
  • “The archaeological record is now showing us that ancient human forms were much more adaptable, and I would say clever, than we imagined,”
  • “This isn’t ‘Flowers for Algernon,’ where, suddenly, we’re super smart and everyone else in the world is behind us.” Scientists are now plumbing genomes for other clues to Homo sapiens’ survival, looking at our metabolisms or resistance to disease, he said. “I’d say the doors have opened, and we haven’t figured out where they lead.”

Gene Therapy Creates Replacement Skin to Save a Dying Boy - The New York Times - 1 views

  • The boy in the Nature article had suffered since birth from blisters all over his body, and in 2015 contracted bacterial infections that caused him to lose two-thirds of his skin. His doctors did not know how to treat him, other than keeping him on morphine for the pain.
  • Doctors in the burn unit tried everything: antibiotics, bandages, special nutritional measures, a skin transplant from the boy’s father. Nothing worked.
  • The doctors removed a sample of the boy’s skin — slightly more than half a square inch — and took it to Modena, where they genetically engineered his cells, using a virus to insert the normal form of his mutated gene into his DNA.Then they grew the engineered cells in the laboratory into sheets of skin and transported them back to Germany, where surgeons grafted them onto the boy’s body.In October 2015, they covered his arms and legs with the new skin, and in November, his back. Ultimately, they replaced 80 percent of the child’s skin.

The Coming Software Apocalypse - The Atlantic - 1 views

  • Our standard framework for thinking about engineering failures—reflected, for instance, in regulations for medical devices—was developed shortly after World War II, before the advent of software, for electromechanical systems. The idea was that you make something reliable by making its parts reliable (say, you build your engine to withstand 40,000 takeoff-and-landing cycles) and by planning for the breakdown of those parts (you have two engines). But software doesn’t break. Intrado’s faulty threshold is not like the faulty rivet that leads to the crash of an airliner. The software did exactly what it was told to do. In fact it did it perfectly. The reason it failed is that it was told to do the wrong thing.
  • Software failures are failures of understanding, and of imagination. Intrado actually had a backup router, which, had it been switched to automatically, would have restored 911 service almost immediately. But, as described in a report to the FCC, “the situation occurred at a point in the application logic that was not designed to perform any automated corrective actions.”
  • The introduction of programming languages like Fortran and C, which resemble English, and tools, known as “integrated development environments,” or IDEs, that help correct simple mistakes (like Microsoft Word’s grammar checker but for code), obscured, though did little to actually change, this basic alienation—the fact that the programmer didn’t work on a problem directly, but rather spent their days writing out instructions for a machine.

  • Code is too hard to think about. Before trying to understand the attempts themselves, then, it’s worth understanding why this might be: what it is about code that makes it so foreign to the mind, and so unlike anything that came before it.
  • Technological progress used to change the way the world looked—you could watch the roads getting paved; you could see the skylines rise. Today you can hardly tell when something is remade, because so often it is remade by code.
  • Software has enabled us to make the most intricate machines that have ever existed. And yet we have hardly noticed, because all of that complexity is packed into tiny silicon chips as millions and millions of lines of cod
  • The programmer, the renowned Dutch computer scientist Edsger Dijkstra wrote in 1988, “has to be able to think in terms of conceptual hierarchies that are much deeper than a single mind ever needed to face before.” Dijkstra meant this as a warning.
  • As programmers eagerly poured software into critical systems, they became, more and more, the linchpins of the built world—and Dijkstra thought they had perhaps overestimated themselves.
  • What made programming so difficult was that it required you to think like a computer.
  • “The problem is that software engineers don’t understand the problem they’re trying to solve, and don’t care to,” says Leveson, the MIT software-safety expert. The reason is that they’re too wrapped up in getting their code to work.
  • Though he runs a lab that studies the future of computing, he seems less interested in technology per se than in the minds of the people who use it. Like any good toolmaker, he has a way of looking at the world that is equal parts technical and humane. He graduated top of his class at the California Institute of Technology for electrical engineering,
  • “The serious problems that have happened with software have to do with requirements, not coding errors.” When you’re writing code that controls a car’s throttle, for instance, what’s important is the rules about when and how and by how much to open it. But these systems have become so complicated that hardly anyone can keep them straight in their head. “There’s 100 million lines of code in cars now,” Leveson says. “You just cannot anticipate all these things.”
  • a nearly decade-long investigation into claims of so-called unintended acceleration in Toyota cars. Toyota blamed the incidents on poorly designed floor mats, “sticky” pedals, and driver error, but outsiders suspected that faulty software might be responsible
  • software experts spend 18 months with the Toyota code, picking up where NASA left off. Barr described what they found as “spaghetti code,” programmer lingo for software that has become a tangled mess. Code turns to spaghetti when it accretes over many years, with feature after feature piling on top of, and being woven around
  • Using the same model as the Camry involved in the accident, Barr’s team demonstrated that there were actually more than 10 million ways for the onboard computer to cause unintended acceleration. They showed that as little as a single bit flip—a one in the computer’s memory becoming a zero or vice versa—could make a car run out of control. The fail-safe code that Toyota had put in place wasn’t enough to stop it
  • . In all, Toyota recalled more than 9 million cars, and paid nearly $3 billion in settlements and fines related to unintended acceleration.
  • The problem is that programmers are having a hard time keeping up with their own creations. Since the 1980s, the way programmers work and the tools they use have changed remarkably little.
  • “Visual Studio is one of the single largest pieces of software in the world,” he said. “It’s over 55 million lines of code. And one of the things that I found out in this study is more than 98 percent of it is completely irrelevant. All this work had been put into this thing, but it missed the fundamental problems that people faced. And the biggest one that I took away from it was that basically people are playing computer inside their head.” Programmers were like chess players trying to play with a blindfold on—so much of their mental energy is spent just trying to picture where the pieces are that there’s hardly any left over to think about the game itself.
  • The fact that the two of them were thinking about the same problem in the same terms, at the same time, was not a coincidence. They had both just seen the same remarkable talk, given to a group of software-engineering students in a Montreal hotel by a computer researcher named Bret Victor. The talk, which went viral when it was posted online in February 2012, seemed to be making two bold claims. The first was that the way we make software is fundamentally broken. The second was that Victor knew how to fix it.
  • This is the trouble with making things out of code, as opposed to something physical. “The complexity,” as Leveson puts it, “is invisible to the eye.”
  • in early 2012, Victor had finally landed upon the principle that seemed to thread through all of his work. (He actually called the talk “Inventing on Principle.”) The principle was this: “Creators need an immediate connection to what they’re creating.” The problem with programming was that it violated the principle. That’s why software systems were so hard to think about, and so rife with bugs: The programmer, staring at a page of text, was abstracted from whatever it was they were actually making.
  • “Our current conception of what a computer program is,” he said, is “derived straight from Fortran and ALGOL in the late ’50s. Those languages were designed for punch cards.”
  • WYSIWYG (pronounced “wizzywig”) came along. It stood for “What You See Is What You Get.”
  • Victor’s point was that programming itself should be like that. For him, the idea that people were doing important work, like designing adaptive cruise-control systems or trying to understand cancer, by staring at a text editor, was appalling.
  • With the right interface, it was almost as if you weren’t working with code at all; you were manipulating the game’s behavior directly.
  • When the audience first saw this in action, they literally gasped. They knew they weren’t looking at a kid’s game, but rather the future of their industry. Most software involved behavior that unfolded, in complex ways, over time, and Victor had shown that if you were imaginative enough, you could develop ways to see that behavior and change it, as if playing with it in your hands. One programmer who saw the talk wrote later: “Suddenly all of my tools feel obsolete.”
  • hen John Resig saw the “Inventing on Principle” talk, he scrapped his plans for the Khan Academy programming curriculum. He wanted the site’s programming exercises to work just like Victor’s demos. On the left-hand side you’d have the code, and on the right, the running program: a picture or game or simulation. If you changed the code, it’d instantly change the picture. “In an environment that is truly responsive,” Resig wrote about the approach, “you can completely change the model of how a student learns ... [They] can now immediately see the result and intuit how underlying systems inherently work without ever following an explicit explanation.” Khan Academy has become perhaps the largest computer-programming class in the world, with a million students, on average, actively using the program each month.
  • The ideas spread. The notion of liveness, of being able to see data flowing through your program instantly, made its way into flagship programming tools offered by Google and Apple. The default language for making new iPhone and Mac apps, called Swift, was developed by Apple from the ground up to support an environment, called Playgrounds, that was directly inspired by Light Table.
  • “Typically the main problem with software coding—and I’m a coder myself,” Bantegnie says, “is not the skills of the coders. The people know how to code. The problem is what to code. Because most of the requirements are kind of natural language, ambiguous, and a requirement is never extremely precise, it’s often understood differently by the guy who’s supposed to code.”
  • In a pair of later talks, “Stop Drawing Dead Fish” and “Drawing Dynamic Visualizations,” Victor went one further. He demoed two programs he’d built—the first for animators, the second for scientists trying to visualize their data—each of which took a process that used to involve writing lots of custom code and reduced it to playing around in a WYSIWYG interface.
  • Victor suggested that the same trick could be pulled for nearly every problem where code was being written today. “I’m not sure that programming has to exist at all,” he told me. “Or at least software developers.” In his mind, a software developer’s proper role was to create tools that removed the need for software developers. Only then would people with the most urgent computational problems be able to grasp those problems directly, without the intermediate muck of code.
  • Victor implored professional software developers to stop pouring their talent into tools for building apps like Snapchat and Uber. “The inconveniences of daily life are not the significant problems,” he wrote. Instead, they should focus on scientists and engineers—as he put it to me, “these people that are doing work that actually matters, and critically matters, and using really, really bad tools.”
  • Bantegnie’s company is one of the pioneers in the industrial use of model-based design, in which you no longer write code directly. Instead, you create a kind of flowchart that describes the rules your program should follow (the “model”), and the computer generates code for you based on those rules
  • In a model-based design tool, you’d represent this rule with a small diagram, as though drawing the logic out on a whiteboard, made of boxes that represent different states—like “door open,” “moving,” and “door closed”—and lines that define how you can get from one state to the other. The diagrams make the system’s rules obvious: Just by looking, you can see that the only way to get the elevator moving is to close the door, or that the only way to get the door open is to stop.
  • . In traditional programming, your task is to take complex rules and translate them into code; most of your energy is spent doing the translating, rather than thinking about the rules themselves. In the model-based approach, all you have is the rules. So that’s what you spend your time thinking about. It’s a way of focusing less on the machine and more on the problem you’re trying to get it to solve.
  • “Everyone thought I was interested in programming environments,” he said. Really he was interested in how people see and understand systems—as he puts it, in the “visual representation of dynamic behavior.” Although code had increasingly become the tool of choice for creating dynamic behavior, it remained one of the worst tools for understanding it. The point of “Inventing on Principle” was to show that you could mitigate that problem by making the connection between a system’s behavior and its code immediate.
  • On this view, software becomes unruly because the media for describing what software should do—conversations, prose descriptions, drawings on a sheet of paper—are too different from the media describing what software does do, namely, code itself.
  • for this approach to succeed, much of the work has to be done well before the project even begins. Someone first has to build a tool for developing models that are natural for people—that feel just like the notes and drawings they’d make on their own—while still being unambiguous enough for a computer to understand. They have to make a program that turns these models into real code. And finally they have to prove that the generated code will always do what it’s supposed to.
  • tice brings order and accountability to large codebases. But, Shivappa says, “it’s a very labor-intensive process.” He estimates that before they used model-based design, on a two-year-long project only two to three months was spent writing code—the rest was spent working on the documentation.
  • uch of the benefit of the model-based approach comes from being able to add requirements on the fly while still ensuring that existing ones are met; with every change, the computer can verify that your program still works. You’re free to tweak your blueprint without fear of introducing new bugs. Your code is, in FAA parlance, “correct by construction.”
  • “people are not so easily transitioning to model-based software development: They perceive it as another opportunity to lose control, even more than they have already.”
  • The bias against model-based design, sometimes known as model-driven engineering, or MDE, is in fact so ingrained that according to a recent paper, “Some even argue that there is a stronger need to investigate people’s perception of MDE than to research new MDE technologies.”
  • “Human intuition is poor at estimating the true probability of supposedly ‘extremely rare’ combinations of events in systems operating at a scale of millions of requests per second,” he wrote in a paper. “That human fallibility means that some of the more subtle, dangerous bugs turn out to be errors in design; the code faithfully implements the intended design, but the design fails to correctly handle a particular ‘rare’ scenario.”
  • Newcombe was convinced that the algorithms behind truly critical systems—systems storing a significant portion of the web’s data, for instance—ought to be not just good, but perfect. A single subtle bug could be catastrophic. But he knew how hard bugs were to find, especially as an algorithm grew more complex. You could do all the testing you wanted and you’d never find them all.
  • An algorithm written in TLA+ could in principle be proven correct. In practice, it allowed you to create a realistic model of your problem and test it not just thoroughly, but exhaustively. This was exactly what he’d been looking for: a language for writing perfect algorithms.
  • TLA+, which stands for “Temporal Logic of Actions,” is similar in spirit to model-based design: It’s a language for writing down the requirements—TLA+ calls them “specifications”—of computer programs. These specifications can then be completely verified by a computer. That is, before you write any code, you write a concise outline of your program’s logic, along with the constraints you need it to satisfy
  • Programmers are drawn to the nitty-gritty of coding because code is what makes programs go; spending time on anything else can seem like a distraction. And there is a patient joy, a meditative kind of satisfaction, to be had from puzzling out the micro-mechanics of code. But code, Lamport argues, was never meant to be a medium for thought. “It really does constrain your ability to think when you’re thinking in terms of a programming language,”
  • Code makes you miss the forest for the trees: It draws your attention to the working of individual pieces, rather than to the bigger picture of how your program fits together, or what it’s supposed to do—and whether it actually does what you think. This is why Lamport created TLA+. As with model-based design, TLA+ draws your focus to the high-level structure of a system, its essential logic, rather than to the code that implements it.
  • But TLA+ occupies just a small, far corner of the mainstream, if it can be said to take up any space there at all. Even to a seasoned engineer like Newcombe, the language read at first as bizarre and esoteric—a zoo of symbols.
  • this is a failure of education. Though programming was born in mathematics, it has since largely been divorced from it. Most programmers aren’t very fluent in the kind of math—logic and set theory, mostly—that you need to work with TLA+. “Very few programmers—and including very few teachers of programming—understand the very basic concepts and how they’re applied in practice. And they seem to think that all they need is code,” Lamport says. “The idea that there’s some higher level than the code in which you need to be able to think precisely, and that mathematics actually allows you to think precisely about it, is just completely foreign. Because they never learned it.”
  • “In the 15th century,” he said, “people used to build cathedrals without knowing calculus, and nowadays I don’t think you’d allow anyone to build a cathedral without knowing calculus. And I would hope that after some suitably long period of time, people won’t be allowed to write programs if they don’t understand these simple things.”
  • Programmers, as a species, are relentlessly pragmatic. Tools like TLA+ reek of the ivory tower. When programmers encounter “formal methods” (so called because they involve mathematical, “formally” precise descriptions of programs), their deep-seated instinct is to recoil.
  • Formal methods had an image problem. And the way to fix it wasn’t to implore programmers to change—it was to change yourself. Newcombe realized that to bring tools like TLA+ to the programming mainstream, you had to start speaking their language.
  • he presented TLA+ as a new kind of “pseudocode,” a stepping-stone to real code that allowed you to exhaustively test your algorithms—and that got you thinking precisely early on in the design process. “Engineers think in terms of debugging rather than ‘verification,’” he wrote, so he titled his internal talk on the subject to fellow Amazon engineers “Debugging Designs.” Rather than bemoan the fact that programmers see the world in code, Newcombe embraced it. He knew he’d lose them otherwise. “I’ve had a bunch of people say, ‘Now I get it,’” Newcombe says.

What Biden's May 1 COVID-19 Vaccine Deadline Means For You | HuffPost Life - 0 views

  • President Joe Biden also said in an address on Thursday that all Americans would be eligible for a COVID-19 vaccine by May 1
  • Now, this does not necessarily mean everyone in the country will be rolling up their sleeves on that day. The general public may start scheduling appointments in early May, but it’s probably going to take a few months to work through the general population.
  • So far, the vaccine rollout has been sticky — it’s difficult to secure an appointment and supply continues to be tight across the country.
  • ...7 more annotations...
  • The country will also need to open more vaccination sites, some of which should be open 24/7 to ensure people who get off work at odd hours have easy access to the vaccine.“This is a wartime sort of response,” Fagbuyi said. “You’re going to pull all the stops and not leave any stone unturned.”
  • “Enjoy the opportunity, but also be cautious and look at what’s going on around you,” Fagbuyi said.
  • “We’re going to be trying to convince people to come get vaccinated,” Adalja said.
  • Adalja predicts that by the Fourth of July, vulnerable people will be vaccinated in all states and there will no longer be concerns about reaching hospital capacity.
  • So, when will we get to a point where it won’t be so complicated for the general public to score a vaccine appointment? Fagbuyi predicts sometime in June.
  • We often hear doctors say we want 70% of the population to be immune to COVID-19, whether through vaccination, natural infection or preexisting immunity, to achieve herd immunity. Each dose pricked in someone’s arm makes it harder for the virus to spread.
  • “What I think is more important than herd immunity is making sure vulnerable populations are vaccinated so that COVID loses the ability to cause severe illness, hospitalization and death,” Adalja said.

Michio Kaku Says the Universe Is Simpler Than We Think - The New York Times - 0 views

  • As the title suggests, Kaku’s latest concern is with what he calls the “holy grail” of all science, the metaphorical “umbilical cord” of our infant universe, whenever it was (or wasn’t) born out of the alleged multiverse. He wanted to write a balanced account of the physics community’s quest to prove string theory — and thus to resolve the messy, imperfect Standard Model of subatomic particles into one elegant theory of everything

Every time you put them together it blows up in your face. Why should nature be so clumsy?”

Opinion | The 1619 Chronicles - The New York Times - 0 views

  • The 1619 Project introduced a date, previously obscure to most Americans, that ought always to have been thought of as seminal — and probably now will. It offered fresh reminders of the extent to which Black freedom was a victory gained by courageous Black Americans, and not just a gift obtained from benevolent whites.
  • in a point missed by many of the 1619 Project’s critics, it does not reject American values. As Nikole Hannah-Jones, its creator and leading voice, concluded in her essay for the project, “I wish, now, that I could go back to the younger me and tell her that her people’s ancestry started here, on these lands, and to boldly, proudly, draw the stars and those stripes of the American flag.” It’s an unabashedly patriotic thought.
  • ambition can be double-edged. Journalists are, most often, in the business of writing the first rough draft of history, not trying to have the last word on it. We are best when we try to tell truths with a lowercase t, following evidence in directions unseen, not the capital-T truth of a pre-established narrative in which inconvenient facts get discarded
  • ...25 more annotations...
  • on these points — and for all of its virtues, buzz, spinoffs and a Pulitzer Prize — the 1619 Project has failed.
  • That doesn’t mean that the project seeks to erase the Declaration of Independence from history. But it does mean that it seeks to dethrone the Fourth of July by treating American history as a story of Black struggle against white supremacy — of which the Declaration is, for all of its high-flown rhetoric, supposed to be merely a part.
  • he deleted assertions went to the core of the project’s most controversial goal, “to reframe American history by considering what it would mean to regard 1619 as our nation’s birth year.”
  • She then challenged me to find any instance in which the project stated that “using 1776 as our country’s birth date is wrong,” that it “should not be taught to schoolchildren,” and that the only one “that should be taught” was 1619. “Good luck unearthing any of us arguing that,” she added.
  • I emailed her to ask if she could point to any instances before this controversy in which she had acknowledged that her claims about 1619 as “our true founding” had been merely metaphorical. Her answer was that the idea of treating the 1619 date metaphorically should have been so obvious that it went without saying.
  • “1619. It is not a year that most Americans know as a notable date in our country’s history. Those who do are at most a tiny fraction of those who can tell you that 1776 is the year of our nation’s birth. What if, however, we were to tell you that this fact, which is taught in our schools and unanimously celebrated every Fourth of July, is wrong, and that the country’s true birth date, the moment that its defining contradictions first came into the world, was in late August of 1619?”
  • Here is an excerpt from the introductory essay to the project by The New York Times Magazine’s editor, Jake Silverstein, as it appeared in print in August 2019 (italics added):
  • In his introduction, Silverstein argues that America’s “defining contradictions” were born in August 1619, when a ship carrying 20 to 30 enslaved Africans from what is present-day Angola arrived in Point Comfort, in the English colony of Virginia. And the title page of Hannah-Jones’s essay for the project insists that “our founding ideals of liberty and equality were false when they were written.”
  • What was surprising was that in 1776 a politically formidable “defining contradiction” — “that all men are created equal” — came into existence through the Declaration of Independence. As Abraham Lincoln wrote in 1859, that foundational document would forever serve as a “rebuke and stumbling block to the very harbingers of reappearing tyranny and oppression.”
  • As for the notion that the Declaration’s principles were “false” in 1776, ideals aren’t false merely because they are unrealized, much less because many of the men who championed them, and the nation they created, hypocritically failed to live up to them.
  • These two flaws led to a third, conceptual, error. “Out of slavery — and the anti-Black racism it required — grew nearly everything that has truly made America exceptional,” writes Silverstein.
  • Nearly everything? What about, say, the ideas contained by the First Amendment? Or the spirit of openness that brought millions of immigrants through places like Ellis Island? Or the enlightened worldview of the Marshall Plan and the Berlin airlift? Or the spirit of scientific genius and discovery exemplified by the polio vaccine and the moon landing?
  • On the opposite side of the moral ledger, to what extent does anti-Black racism figure in American disgraces such as the brutalization of Native Americans, the Chinese Exclusion Act or the internment of Japanese-Americans in World War II?
  • The world is complex. So are people and their motives. The job of journalism is to take account of that complexity, not simplify it out of existence through the adoption of some ideological orthodoxy.
  • This mistake goes far to explain the 1619 Project’s subsequent scholarly and journalistic entanglements. It should have been enough to make strong yet nuanced claims about the role of slavery and racism in American history. Instead, it issued categorical and totalizing assertions that are difficult to defend on close examination.
  • It should have been enough for the project to serve as curator for a range of erudite and interesting voices, with ample room for contrary takes. Instead, virtually every writer in the project seems to sing from the same song sheet, alienating other potential supporters of the project and polarizing national debate.
  • James McPherson, the Pulitzer Prize-winning author of “Battle Cry of Freedom” and a past president of the American Historical Association. He was withering: “Almost from the outset,” McPherson told the World Socialist Web Site, “I was disturbed by what seemed like a very unbalanced, one-sided account, which lacked context and perspective.”
  • In particular, McPherson objected to Hannah-Jones’s suggestion that the struggle against slavery and racism and for civil rights and democracy was, if not exclusively then mostly, a Black one. As she wrote in her essay: “The truth is that as much democracy as this nation has today, it has been borne on the backs of Black resistance.”
  • McPherson demurs: “From the Quakers in the 18th century, on through the abolitionists in the antebellum, to the Radical Republicans in the Civil War and Reconstruction, to the N.A.A.C.P., which was an interracial organization founded in 1909, down through the civil rights movements of the 1950s and 1960s, there have been a lot of whites who have fought against slavery and racial discrimination, and against racism,” he said. “And that’s what’s missing from this perspective.”
  • Wilentz’s catalog of the project’s mistakes is extensive. Hannah-Jones’s essay claimed that by 1776 Britain was “deeply conflicted” over its role in slavery. But despite the landmark Somerset v. Stewart court ruling in 1772, which held that slavery was not supported by English common law, it remained deeply embedded in the practices of the British Empire. The essay claimed that, among Londoners, “there were growing calls to abolish the slave trade” by 1776. But the movement to abolish the British slave trade only began about a decade later — inspired, in part, Wilentz notes, by American antislavery agitation that had started in the 1760s and 1770s.
  • ie M. Harris, an expert on pre-Civil War African-American life and slavery. “On Aug. 19 of last year,” Harris wrote, “I listened in stunned silence as Nikole Hannah-Jones … repeated an idea that I had vigorously argued against with her fact checker: that the patriots fought the American Revolution in large part to preserve slavery in North America.”
  • The larger problem is that The Times’s editors, however much background reading they might have done, are not in a position to adjudicate historical disputes. That should have been an additional reason for the 1619 Project to seek input from, and include contributions by, an intellectually diverse range of scholarly voices. Yet not only does the project choose a side, it also brooks no doubt.
  • “It is finally time to tell our story truthfully,” the magazine declares on its 1619 cover page. Finally? Truthfully? Is The Times suggesting that distinguished historians, like the ones who have seriously disputed aspects of the project, had previously been telling half-truths or falsehoods?
  • unlike other dates, 1776 uniquely marries letter and spirit, politics and principle: The declaration that something new is born, combined with the expression of an ideal that — because we continue to believe in it even as we struggle to live up to it — binds us to the date.
  • On the other, the 1619 Project has become, partly by its design and partly because of avoidable mistakes, a focal point of the kind of intense national debate that columnists are supposed to cover, and that is being widely written about outside The Times. To avoid writing about it on account of the first scruple is to be derelict in our responsibility toward the second.

  • The Importance of a Positive Classroom

  • Such an environment provides relevant content, clear learning goals and feedback, opportunities to build social skills, and strategies to help students succeed
  • We all know the factors that can threaten a positive classroom environment: problems that kids bring from home, lack of motivation among students whose love of learning has been drilled right out of them, pressures from testing, and more
  • We can't control all these factors, but what if we could implement some simple strategies to buffer against their negative effects?
  • We can foster effective learning and transform the experience of our students every day by harnessing the power of emotions.
  • don't worry: I'm not talking about holding a daily class meeting to talk about feelings.
  • Stress, for example, has a significant negative effect on cognitive functioning
  • Unfortunately, when it comes to learning processes, the power of negative events greatly outweighs the power of positive event
  • As a result, we need to prepare ourselves with an arsenal of strategies that inoculate our students against the power of negativity.
  • By providing enough positive experiences to counteract the negative, we can help students avoid getting stuck in a "negative spiral"
  • Being caught up in negative emotions in this way impairs learning by narrowing students' focus and inhibiting their ability to see multiple viewpoints and solve problems.
  • This publication is not a cheat sheet, a "happyology" manual, or a Band-Aid that will fix that distressed kid and send him to a magical haven of learning.
  • Far from promising easy solutions and instant results, these strategies will increase students' capacity to tolerate the discomfort that comes with working hard and to accept that there are no easy answers—that only critical thinking and perseverance lead the way to mastery.
  • pause every 10 minutes and simply observe how many students are actively engaged and how many are off task.
  • If it is too challenging to chart the behavior of each student, you can choose a sample of the class to observe.
  • Remember to keep a full observation stance, and try not to leap to judgment. Keep in mind various "factors of mass distraction" that may contribute to problems , such as people entering or leaving the room, noise level, students' seating locations, and time of day. You might also want to note the affect or mood of students as they come into class that day.
  • As for the less productive moments you identify, the following strategies will help you create an environment that is more conducive to engagement and learning.

Why the Coronavirus Could Threaten the U.S. Economy Even More Than China's - The New Yo... - 0 views

  • After a string of deaths, some heart-stopping plunges in the stock market and an emergency rate cut by the Federal Reserve, there is reason to be concerned about the ultimate economic impact of the coronavirus in the United States.
  • Advanced economies like the United States are hardly immune to these effects. To the contrary, a broad outbreak of the disease in them could be even worse for their economies than in China. That is because face-to-face service industries — the kind of businesses that go into a tailspin when fearful people withdraw from one another — tend to dominate economies in high-income countries more than they do in China.
  • If people stay home from school, stop traveling and don’t go to sporting events, the gym or the dentist, the economic consequence would be worse
  • ...7 more annotations...
  • With shortages of everything from auto parts to generic medicines and production delays in things like iPhones and Diet Coke, a great deal of pain is coming from the closing of Chinese factories. That proliferating damage has central banks and financial analysts talking about a global recession in the coming months.
  • As a baseline, several factors work against the United States. China’s authoritarian government can quarantine entire cities or order people off the streets in a way that would be hard to imagine in America, presumably giving China an advantage in slowing the spread of the disease. In addition, a large share of American workers lack paid sick days and millions lack health care coverage, so people may be less likely to stay home or to get proper medical care. And 41 percent of China’s population lives outside urban areas, more than twice the share in the United States. Diseases generally spread faster in urban areas.
  • When people pull back from interacting with others because of their fear of disease, the things they stop doing will frequently affect much bigger industries in the United States.
  • People may stop attending American sporting events. There have even been calls for the N.C.A.A. to play its March Madness college basketball tournament without an audience. But sports is a huge business in the United States. People spend upward of 10 times as much on sporting events as they do in China.
  • Who wants to go to the dentist or the hospital during an outbreak if a visit isn’t necessary? Yet health spending is 17 percent of the U.S. economy — more than triple the proportion spent in China.
  • But over all, the United States is substantially more reliant on services than China is.
  • A major coronavirus epidemic in the United States might be like a big snowstorm that shuts down most economic activity and social interaction only until the snow is cleared away. But the coronavirus could be a “Snowmaggedon-style storm” that hits the whole country and lasts for months.

Climate Change Data Deluge Has Scientists Scrambling for Solutions - WSJ - 0 views

  • For decades, scientists working to predict changes in the climate relied mostly on calculations involving simple laws of physics and chemistry but little data from the real world. But with temperatures world-wide continuing to rise—and with data-collection techniques and technologies continuing to advance—scientists now rely on meticulous measurements of temperatures, ocean currents, soil moisture, air quality, cloud cover and hundreds of other phenomena on Earth and in its atmosphere.

Opinion: No more union-busting. It's time for companies to give their workers what they... - 0 views

  • This year, workers at Amazon, Starbucks and other major corporations are winning a wave of union elections, often in the face of long odds and employer resistance. These wins are showing it's possible for determined groups of workers to break through powerful employers' use of union-busting tactics, ranging from alleged retaliatory firings to alleged surveillance and forced attendance at anti-union "captive audience meetings." But workers should not have to confront so many obstacles to exercising a guaranteed legal right to unionize and bargain for improvements in their work lives and livelihoods.
  • For decades, wage suppression, growing income inequality and persistent racial and gender wage gaps have characterized the US labor market.
  • But now, as workers are pointing the way to better workplaces and a more equitable economy, employers and policymakers need to pay attention. Policymakers must better protect workers' union rights, and employers must start respecting workers' right to participate in union elections without interference or coercion.

  • Unions are among the most effective mechanisms available for addressing massive economic inequalities. Congress should adopt labor law reforms to better protect workers' right to organize, starting with the widely popular Protecting the Right to Organize (PRO) Act. Among other things, the PRO Act would create the first serious monetary penalties for employers that retaliate against workers for unionizing.
  • Congress must also adequately fund the National Labor Relations Board (NLRB) so the agency can enforce labor law.
  • Many US workers say they want a union, but far too few have one. Right now, workers who've won recent union elections are inviting employers to meet them as equals and start bargaining union contracts.
  • Labor unions are highly correlated with safer conditions because they give workers a voice in setting workplace policies and the ability to engage management in addressing concerns without fear of retaliation.
  • The Black-led, multiracial committees that have led organizing drives at Amazon warehouses and the young women baristas leading breakthrough organizing victories at Starbucks are changing the public face of the labor movement in powerful and promising ways.
  • Two-thirds of union workers are women and/or workers of color.
  • In any company, the transparency and consistency of a union contract that sets wage rates, scheduled raises and procedures for promotions helps guard against forms of discriminatory bias that otherwise disadvantage women and workers of color.
  • Unionizing workers will continue to need extraordinary solidarity, persistence and public support in order to succeed. This is a moment of opportunity for all of us. Anyone ready to start reversing the worst economic inequalities the US has seen in almost a century can choose now to join and support workers who are organizing unions.

  • Each week, students would read about a different monastic tradition and adopt some of its practices. Later in the semester, they would observe a one-month vow of silence (except for discussions during Living Deliberately) and fast from technology, handing over their phones to him.

  • Yes, he knew they had other classes, jobs and extracurriculars; they could make arrangements to do that work silently and without a computer.
  • The class eased into the vow of silence, first restricting speech to 100 words a day. Other rules began on Day 1: no jewelry or makeup in class. Men and women sat separately and wore different “habits”: white shirts for the men, women in black. (Nonbinary and transgender students sat with the gender of their choice.)
  • Dr. McDaniel discouraged them from sharing personal information; they should get to know one another only through ideas. “He gave us new names, based on our birth time and day, using a Thai birth chart,”
  • “We were practicing living a monastic life. We had to wake up at 5 a.m. and journal every 30 minutes.”
  • If you tried to cruise to a C, you missed the point: “I realized the only way for me to get the most out of this class was to experience it all,” she said. (She got Dr. McDaniel’s permission to break her vow of silence in order to talk to patients during her clinical rotation.)
  • Dr. McDaniel also teaches a course called Existential Despair. Students meet once a week from 5 p.m. to midnight in a building with comfy couches, turn over their phones and curl up to read an assigned novel (cover to cover) in one sitting — books like James Baldwin’s “Giovanni’s Room” and José Saramago’s “Blindness.” Then they stay up late discussing it.
  • The course is not about hope, overcoming things, heroic stories,” Dr. McDaniel said. Many of the books “start sad. In the middle they’re sad. They stay sad. I’m not concerned with their 20-year-old self. I’m worried about them at my age, dealing with breast cancer, their dad dying, their child being an addict, a career that never worked out — so when they’re dealing with the bigger things in life, they know they’re not alone.”
  • Both courses have long wait lists. Students are hungry for a low-tech, introspective experience —
  • Research suggests that underprivileged young people have far fewer opportunities to think for unbroken stretches of time, so they may need even more space in college to develop what social scientists call cognitive endurance.
  • Yet the most visible higher ed trends are moving in the other direction
  • Rather than ban phones and laptops from class, some professors are brainstorming ways to embrace students’ tech addictions with class Facebook and Instagram accounts, audience response apps — and perhaps even including the friends and relatives whom students text during class as virtual participants in class discussion.
  • Then there’s that other unwelcome classroom visitor: artificial intelligence.
  • stop worrying and love the bot by designing assignments that “help students develop their prompting skills” or “use ChatGPT to generate a first draft,” according to a tip sheet produced by the Center for Teaching and Learning at Washington University in St. Louis.
  • It’s not at all clear that we want a future dominated by A.I.’s amoral, Cheez Whiz version of human thought
  • It is abundantly clear that texting, tagging and chatbotting are making students miserable right now.
  • One recent national survey found that 60 percent of American college students reported the symptoms of at least one mental health problem and that 15 percent said they were considering suicide
  • A recent meta-analysis of 36 studies of college students’ mental health found a significant correlation between longer screen time and higher risk of anxiety and depression
  • And while social media can sometimes help suffering students connect with peers, research on teenagers and college students suggests that overall, the support of a virtual community cannot compensate for the vortex of gossip, bullying and Instagram posturing that is bound to rot any normal person’s self-esteem.
  • We need an intervention: maybe not a vow of silence but a bold move to put the screens, the pinging notifications and creepy humanoid A.I. chatbots in their proper place
  • it does mean selectively returning to the university’s roots in the monastic schools of medieval Europe and rekindling the old-fashioned quest for meaning.
  • Colleges should offer a radically low-tech first-year program for students who want to apply: a secular monastery within the modern university, with a curated set of courses that ban glowing rectangles of any kind from the classroom
  • Students could opt to live in dorms that restrict technology, too
  • I prophesy that universities that do this will be surprised by how much demand there is. I frequently talk to students who resent the distracting laptops all around them during class. They feel the tug of the “imaginary string attaching me to my phone, where I have to constantly check it,”
  • Many, if not most, students want the elusive experience of uninterrupted thought, the kind where a hash of half-baked notions slowly becomes an idea about the world.
  • Even if your goal is effective use of the latest chatbot, it behooves you to read books in hard copies and read enough of them to learn what an elegant paragraph sounds like. How else will students recognize when ChatGPT churns out decent prose instead of bureaucratic drivel?
  • Most important, students need head space to think about their ultimate values.
  • His course offers a chance to temporarily exchange those unconscious structures for a set of deliberate, countercultural ones.
  • here are the student learning outcomes universities should focus on: cognitive endurance and existential clarity.
  • Contemplation and marathon reading are not ends in themselves or mere vacations from real life but are among the best ways to figure out your own answer to the question of what a human being is for
  • When students finish, they can move right into their area of specialization and wire up their skulls with all the technology they want, armed with the habits and perspective to do so responsibly
  • it’s worth learning from the radicals. Dr. McDaniel, the religious studies professor at Penn, has a long history with different monastic traditions. He grew up in Philadelphia, educated by Hungarian Catholic monks. After college, he volunteered in Thailand and Laos and lived as a Buddhist monk.
  • e found that no amount of academic reading could help undergraduates truly understand why “people voluntarily take on celibacy, give up drinking and put themselves under authorities they don’t need to,” he told me. So for 20 years, he has helped students try it out — and question some of their assumptions about what it means to find themselves.
  • “On college campuses, these students think they’re all being individuals, going out and being wild,” he said. “But they’re in a playpen. I tell them, ‘You know you’ll be protected by campus police and lawyers. You have this entire apparatus set up for you. You think you’re being an individual, but look at your four friends: They all look exactly like you and sound like you. We exist in these very strict structures we like to pretend don’t exist.’”
  • Colleges could do all this in classes integrated with general education requirements: ideally, a sequence of great books seminars focused on classic texts from across different civilizations.
  • “For the last 1,500 years, Benedictines have had to deal with technology,” Placid Solari, the abbot there, told me. “For us, the question is: How do you use the tool so it supports and enhances your purpose or mission and you don’t get owned by it?”
  • for novices at his monastery, “part of the formation is discipline to learn how to control technology use.” After this initial time of limited phone and TV “to wean them away from overdependence on technology and its stimulation,” they get more access and mostly make their own choices.
  • Evan Lutz graduated this May from Belmont Abbey with a major in theology. He stressed the special Catholic context of Belmont’s resident monks; if you experiment with monastic practices without investigating the whole worldview, it can become a shallow kind of mindfulness tourism.
  • The monks at Belmont Abbey do more than model contemplation and focus. Their presence compels even non-Christians on campus to think seriously about vocation and the meaning of life. “Either what the monks are doing is valuable and based on something true, or it’s completely ridiculous,” Mr. Lutz said. “In both cases, there’s something striking there, and it asks people a question.”
  • Pondering ultimate questions and cultivating cognitive endurance should not be luxury goods.
  • David Peña-Guzmán, who teaches philosophy at San Francisco State University, read about Dr. McDaniel’s Existential Despair course and decided he wanted to create a similar one. He called it the Reading Experiment. A small group of humanities majors gathered once every two weeks for five and a half hours in a seminar room equipped with couches and a big round table. They read authors ranging from Jean-Paul Sartre to Frantz Fanon
  • “At the beginning of every class I’d ask students to turn off their phones and put them in ‘the Basket of Despair,’ which was a plastic bag,” he told me. “I had an extended chat with them about accessibility. The point is not to take away the phone for its own sake but to take away our primary sources of distraction. Students could keep the phone if they needed it. But all of them chose to part with their phones.”
  • Dr. Peña-Guzmán’s students are mostly working-class, first-generation college students. He encouraged them to be honest about their anxieties by sharing his own: “I said, ‘I’m a very slow reader, and it’s likely some or most of you will get further in the text than me because I’m E.S.L. and read quite slowly in English.’
  • For his students, the struggle to read long texts is “tied up with the assumption that reading can happen while multitasking and constantly interacting with technologies that are making demands on their attention, even at the level of a second,”
  • “These draw you out of the flow of reading. You get back to the reading, but you have to restart the sentence or even the paragraph. Often, because of these technological interventions into the reading experience, students almost experience reading backward — as constant regress, without any sense of progress. The more time they spend, the less progress they make.”
  • Dr. Peña-Guzmán dismissed the idea that a course like his is suitable only for students who don’t have to worry about holding down jobs or paying off student debt. “I’m worried by this assumption that certain experiences that are important for the development of personality, for a certain kind of humanistic and spiritual growth, should be reserved for the elite, especially when we know those experiences are also sources of cultural capital,
  • Courses like the Reading Experiment are practical, too, he added. “I can’t imagine a field that wouldn’t require some version of the skill of focused attention.”
  • The point is not to reject new technology but to help students retain the upper hand in their relationship with i
  • Ms. Rodriguez said that before she took Living Deliberately and Existential Despair, she didn’t distinguish technology from education. “I didn’t think education ever went without technology. I think that’s really weird now. You don’t need to adapt every piece of technology to be able to learn better or more,” she said. “It can form this dependency.”
  • The point of college is to help students become independent humans who can choose the gods they serve and the rules they follow rather than allow someone else to choose for them
  • The first step is dethroning the small silicon idol in their pocket — and making space for the uncomfortable silence and questions that follow
