The Tiny Swiss Company That Thinks It Can Help Stop Climate Change - The New York Times - 0 views

  • The scientist and historian Vaclav Smil called Haber-Bosch “the most important technical invention of the 20th century.” Bosch had effectively removed the historical bounds on crop yields, so much so that he was widely credited with making “bread from air.” By some estimates, Bosch’s work made possible the lives of more than two billion human beings over the last 100 years.
  • They depend on electric fans to pull air into the ducts and over a special material, known as a sorbent, laced with granules that chemically bind with CO₂; periodic blasts of heat then release the captured gas from the sorbent, with customized software managing the whole catch-and-release cycle.
  • “The first thing they said was: ‘This will never work technically.’ And finally in 2017 we convinced them it works technically, since we built the big plant in Hinwil. But once we convinced them that it works technically, they would say, ‘Well, it will never work economically.’ ”For the moment, skeptics of Climeworks’s business plan are correct: The company is not turning a profit.

  • it faces the same daunting task that confronted Carl Bosch a century ago: How much can it bring costs down? And how fast can it scale up
  • They believe that over the next seven years they can bring expenses down to a level that would enable them to sell CO₂ into more lucrative markets. Air-captured CO₂ can be combined with hydrogen and then fashioned into any kind of fossil-fuel substitute you want. Instead of making bread from air, you can make fuels from air.
  • What Gebald and Wurzbacher really want to do is to pull vast amounts of CO₂ out of the atmosphere and bury it, forever, deep underground, and sell that service as an offset
  • companies like Climeworks face a quandary: How do you sell something that never existed before, something that may never be cheap, into a market that is not yet real?
  • It’s arguably the case, in fact, that when it comes to reducing our carbon emissions, direct air capture will be seen as an option that’s too expensive and too modest in impact. “The only way that direct air capture becomes meaningful is if we do all the other things we need to do promptly,” Hal Harvey, a California energy analyst who studies climate-friendly technologies and policies, told me
  • In short, the best way to start making progress toward a decarbonized world is not to rev up millions of air capture machines right now. It’s to stop putting CO₂ in the atmosphere in the first place.
  • If the nations of the world were to continue on the current track, it would be impossible to meet the objectives of the 2016 Paris Agreement, which set a goal limiting warming to 2 degrees Celsius or, ideally, 1.5 degrees. And it would usher in a world of misery and economic hardship. Already, temperatures in some regions have climbed more than 1 degree Celsius, as a report by the Intergovernmental Panel on Climate Change noted last October. These temperature increases have led to an increase in droughts, heat waves, floods and biodiversity losses and make the chaos of 2 or 3 degrees’ additional warming seem inconceivable
  • A further problem is that maintaining today’s emissions path for too long runs the risk of doing irreparable damage to the earth’s ecosystems — causing harm that no amount of technological innovation can make right. “There is no reverse gear for natural systems,” Harvey says. “If they go, they go. If we defrost the tundra, it’s game over.” The same might be said for the Greenland and West Antarctic ice sheets, or our coral reefs. Such resources have an asymmetry in their natural architectures: They can take thousands or millions of years to form, but could reach conditions of catastrophic decline in just a few decades.
  • To have a shot at maintaining a climate suitable for humans, the world’s nations most likely have to reduce CO₂ emissions drastically from the current level — to perhaps 15 billion or 20 billion metric tons per year by 2030; then, through some kind of unprecedented political and industrial effort, we need to bring carbon emissions to zero by around 2050
  • To preserve a livable environment we may also need to extract CO₂ from the atmosphere. As Wurzbacher put it, “if you take all these numbers from the I.P.C.C., you end up with something like eight to 10 billion tons — gigatons — of CO₂ that need to be removed from the air every year, if we are serious about 1.5 or 2 degrees.
  • Through photosynthesis, our forests take extraordinary amounts of carbon dioxide from the atmosphere, and if we were to magnify efforts to reforest clear-cut areas — or plant new groves, a process known as afforestation — we could absorb billions more metric tons of carbon in future years.
  • we could grow crops specifically to absorb CO₂ and then burn them for power generation, with the intention of capturing the power-plant emissions and pumping them underground, a process known as bioenergy with carbon capture and storage, or BECCS
  • Ever since the Industrial Revolution, human societies have produced an excess of CO₂, by taking carbon stores from deep inside the earth — in the form of coal, oil and gas — and from stores aboveground (mostly wood), then putting it into the atmosphere by burning it. It has become imperative to reverse the process — that is, take CO₂ out of the air and either restore it deep inside the earth or contain it within new surface ecosystems.
  • “It’s not about saying, ‘I want to plant a tree.’ It’s about saying, ‘We want to plant a billion trees.’
  • “We have to come to grips with the fact that we waited too long and that we took some options off the table,” Michael Oppenheimer, a Princeton scientist who studies climate and policy, told me. As a result, NETs no longer seem to be just interesting ideas; they look like necessities. And as it happens, the Climeworks machines on the rooftop do the work each year of about 36,000 trees.
  • air capture could likewise help counter the impact of several vital industries. “There are process emissions that come from producing iron and steel, cement and glass,” she says, “and any time you make these materials, there’s a chemical reaction that emits CO₂.” Direct air capture could even lessen the impacts of the Haber-Bosch processes for making fertilizer; by some estimates, that industry now accounts for 3 percent of all CO₂ emissions.
  • Wind and solar are now the cheapest forms of energy in the right locations,” Pacala says. “The return on those investments, if you calculated it, would blow the doors off anything in your portfolio. It’s like investing in early Apple. So it’s a spectacular story of success. And direct air capture is precisely the same kind of problem, in which the only barrier is that it’s too costly.”
  • what all the founders have in common is a belief that the cost of capturing a ton of carbon will soon drop sharply.
  • M.I.T.’s Howard Herzog, for instance, an engineer who has spent years looking at the potential for these machines, told me that he thinks the costs will remain between $600 and $1,000 per metric ton
  • He points out that because direct-air-capture machines have to move tremendous amounts of air through a filter or solution to glean a ton of CO₂ — the gas, for all its global impact, makes up only about 0.04 percent of our atmosphere — the process necessitates large expenditures for energy and big equipment. What he has likewise observed, in analyzing similar industries that separate gases, suggests that translating spreadsheet projections for capturing CO₂ into real-world applications will reveal hidden costs. “I think there has been a lot of hype about this, and it’s not going to revolutionize anything,
  • Climeworks’s current goal is to remove 1 percent of the world’s annual CO₂ emissions by the mid 2020s.
  • “Basically, we have a road map — $600, down to $400, down to $300 and $200 a ton,” Wurzbacher said. “This is over the next five years. Down to $200 we know quite well what we’re doing.” And beyond $200, Wurzbacher suggested, things get murkier.
  • To actually capture 1 percent of the world’s carbon emissions by 2025 would, by Gebald’s calculations, require that Climeworks build 250,000 carbon-capture plants like the ones on the roof at Hinwil. That adds up to about 4.5 million carbon collectors
  • The Climeworks founders therefore try to think of their product as the automotive industry might — a piece of mass-produced technology and metal, not the carbon they hope to sequester.
  • “Every CO₂ collector has about the same weight and dimensions of a car — roughly two tons, and roughly 2 meters by 2 meters by 2 meters,” Gebald said. “And all the methods used to produce the CO₂ collectors could be well automated. So we have the automotive industry as a model for how to produce things in large quantities for low cost.
  • n 1954, the economist Paul Samuelson put forward a theory that made a distinction between “private-consumption goods” — bread, cars, houses and the like — and commodities that existed apart from the usual laws of supply and demand.
  • the other type of commodity Samuelson was describing is something now known as a “public good,” which benefits everyone but is not bought, sold or consumed the same way
  • direct air capture’s success would be limited to the size of the market for private goods — soda fizz, greenhouse gas — unless governments decided to intervene and help fund the equivalent of several million (or more) lighthouses.
  • An intervention could take a variety of forms. It could be large grants for research to find better sorbent materials, for instance, which would be similar to government investments that long ago helped nurture the solar- and wind-power industries. But help could also come by expanding regulations that already exist.
  • The Climeworks founders told me they don’t believe their company will succeed on what they call “climate impact” scales unless the world puts significant prices on emissions, in the form of a carbon tax or carbon fee.
  • “Our goal is to make it possible to capture CO₂ from the air for below $100 per ton,” Wurzbacher says. “No one owns a crystal ball, but we think — and we’re quite confident — that by something like 2030 we’ll have a global average price on carbon in the range of $100 to $150 a ton.” There is optimism in this thinking
  • A company that sells a product or uses a process that creates high emissions — an airline, for instance, or a steel maker — could be required to pay carbon-removal companies $100 per metric ton or more to offset their CO₂ output. Or a government might use carbon-tax proceeds to directly pay businesses to collect and bury CO₂.
  • “It doesn’t cost too much to pump CO₂ underground,” Stanford’s Sally Benson says. Companies already sequester about 34 million metric tons of CO₂ in the ground every year, at a number of sites around the world, usually to enhance the oil-drilling process. “The costs range from $2 to $15 per ton. So the bigger cost in all of this is the cost of carbon capture.”
  • The weekend before, Gutknecht told me, he received 900 unsolicited inquiries by email. Many were from potential customers who wanted to know how soon Climeworks could bury their CO₂ emissions, or how much a machine might cost them.
  • A Climeworks app could be installed on my smartphone, he explained. It could then be activated by my handset’s location services. “You fly over here to Europe,” he explained, “and the app tells you that you have just burned 1.7 tons of CO₂. Do you want to remove that? Well, Climeworks can remove it for you. Click here. We’ll charge your credit card.
  • The vast and constant market demand for fuel is why Carbon Engineering has staked its future on synthetics. The world currently burns about 100 million barrels of oil a day.
  • “So let’s say you’d have to supply something like 50 million barrels a day in 2050 of fuels,” he said. “That’s still a monster market.”
  • Carbon Engineering’s chief executive, added that direct-air-capture synthetics have an advantage over traditional fossil fuels: They won’t have to spend a dime on exploration
  • our plants, you can build it right in the middle of California, wherever you have air and water.” He told me that the company’s first large-scale facility should be up and running by 2022, and will turn out at least 500 barrels a day of fuel feedstock — the raw material sent to refineries.
  • Climeworks recently joined a consortium of European countries to produce synthetic methane that will be used by a local trucking fleet. With different tweaks and refinements, the process could be adapted for diesel, gasoline, jet fuel — or it could be piped directly to local neighborhoods as fuel for home furnaces.
  • the new fuels are not necessarily cheaper. Carbon Engineering aspires to deliver its product at an ultimate retail price of about $1 per liter, or $3.75 per gallon. What would make the product competitive are regulations in California that now require fuel sellers to produce fuels of lower “carbon intensity.” To date this has meant blending gas and diesel with biofuels like ethanol, but it could soon mean carbon-capture synthetics too.
  • Since they’re made from airborne CO₂ and hydrogen and could be manufactured just about anywhere, they could rearrange the geopolitical order — tempering the power of a handful of countries that now control natural-gas and oil markets.
  • From an environmental standpoint, air-capture fuels are not a utopian solution. Such fuels are carbon neutral, not carbon negative. They can’t take CO₂ from our industrial past and put it back into the earth
  • Even so, these fuels could present an enormous improvement. Transportation — currently the most significant source of emissions by sector in the United States — could cease to be a net emitter of CO₂
  • “If you can do one carbon-capture facility, where Carbon Engineering or Climeworks can build a big plant, great. You need to do that 5,000 times. And to capture a million tons of CO₂ with direct air capture, you need a small power plant just to run that facility. So if you’re going to build one direct-air-capture facility every day for the next 30 years to get to some of these scenarios, then in addition, we have to build a new mini power plant every day as well.
  • It’s also the case that you have to address two extraordinary problems at the same time, Peters added. “To reach 1.5 degrees, we need to halve emissions every decade,” he said. That would mean persuading entire nations, like China and the United States, to switch from burning coal to using renewables at precisely the same time that we make immense investments in negative-emission technologies.
  • this would need to be done even as governments choose among competing priorities:
  • “The idea of bringing direct air capture up to 10 billion tons by the middle or later part of the century is such a herculean task it would require an industrial scale-up the likes of which the world has never seen,”
  • Pacala wasn’t pessimistic about making a start. He seemed to think it was necessary for the federal government to begin with significant research and investments in the technology — to see how far and fast it could move forward, so that it’s ready as soon as possible
  • Gebald and Wurzbacher seemed to regard the climate challenge in mathematical terms. How many gigatons needed to be removed? How much would it cost per ton? How many Climeworks machines were required? Even if the figures were enormous, even if they appeared impossible, to see the future their way was to redefine the problem, to move away from the narrative of loss, to forget the multiplying stories of dying reefs and threatened coastlines — and to begin to imagine other possibilities.

In 'The Uninhabitable Earth,' Apocalypse Is Now - The New York Times - 0 views

  • His new book revisits that approach, expanding his portrait of a planetary nightmare that, to judge by climatologists’ assessments, will soon take over our waking life
  • Wallace-Wells is more concerned with the prospect of human suffering and even extinction.
  • “It is about what warming means to the way we live on this planet.” He warns of collapsing ice sheets, water scarcity, an equatorial band too hot to be livable and — for anyone fortunate enough to reside elsewhere — extreme heat waves that will burn longer and kill more. All this could come with 2 degrees Celsius of warming — the threshold that world leaders pledged to stay below in the Paris accords of 2015.

  • he obtains some consolation by peering into the abyss, entertaining the worst-case scenarios of 6 to 8 degrees Celsius of warming. Given the prospect of utter annihilation, he says, the “degraded muddle” that we might still manage to eke out should count “as an encouraging future.” It would be “merely grim, rather than apocalyptic.”
  • The overarching frame for Wallace-Wells’s book is an analogous call to action: “How much will we do to stall disaster, and how quickly?”
  • “The climate system that raised us, and raised everything we now know as human culture and civilization, is now, like a parent, dead,”
  • The harms of global warming tend to fall disproportionately on poorer people and poorer countries, but the “cascades” already set in motion will eventually grow so enormous and indiscriminate that not even the rich will be spared.
  • His New York magazine article already synthesized plenty of information about perilous climate risks and scared the bejeezus out of people; what are we supposed to do with this expanded litany of horrors?
  • He describes himself as a Bitcoin-buying, non-recycling city-dweller who hates camping. He was scared out of his “fatally complacent, and willfully deluded” inertia when he became immersed in the awful truth and, his book suggests, you can be too
  • it’s not as if any of the hair-raising material with which he has become intimately familiar has paralyzed him with fatalism — quite the opposite. “That we know global warming is our doing should be a comfort, not a cause for despair,” he writes. What some activists have called “toxic knowledge” — all the intricate feedback loops of societal collapse — “should be empowering.”
  • even while staring down the bleak decades ahead, Wallace-Wells had a child. “She will watch the world doing battle with a genuinely existential threat,” he writes. “She will be living it — quite literally the greatest story ever told. It may well bring a happy ending.
  • Mobilization is impossible for people who are sleepwalking their way toward disaster; and mobilization is necessary, he says, to deploy the tools at our disposal, which include carbon taxes, carbon capture and green energy.
  • There is no single way to best tell the story of climate change, no single rhetorical approach likely to work on a given audience, and none too dangerous to try,” Wallace-Wells writes. “Any story that sticks is a good one.”
  • detail the possible future that awaits the planet should we continue to add carbon to the atmosphere and fail to arrest global warming. Floods, pestilence, famines, wildfires: What he calls the “elements of climate chaos” are veritably biblical in scope

Ancient DNA is Rewriting Human (and Neanderthal) History - The Atlantic - 0 views

  • Sarah Zhang: You recently published two papers in which you analyzed over 600 genomes from ancient Europeans
  • Reich: In our hands, a successful sample costs less than $200. That’s only two or three times more than processing them on a present-day person
  • Reich: In Europe where we have the best data currently—although that will change over the coming years—we know a lot about how people have migrated. We know of multiple layers of population replacement over the last 50,000 years. Between 41,000 and 39,000 years ago in western Europe, the Neanderthals were replaced by modern human populations. The first modern human samples we have in Europe are about 40,000 years old and are genetically not at all related to present-day Europeans. They seem to be from extinct, dead-end groups.
  • ...16 more annotations...
  • After that, you see for the first time people related to later European hunter-gatherers who have contributed a little bit to present-day Europeans. That happens beginning 35,000 to 37,000 years ago. Then the ice sheets descend across northern Europe and a lot of these populations are chased into these refuges in the southern peninsulas of Europe. After the Ice Age, there’s a repeopling of northern Europe from the southwest, probably from Spain, and then also from the southeast, probably from Greece and maybe even from Anatolia, Turkey
  • Again, after 9,000 years ago, there’s a mass movement of farmers into the region which almost completely replaces the hunter-gatherers with a small amount of mixture
  • And then again, after 5,000 years ago, there’s this mass movement at the beginning of the Bronze Age of people from the steppe, who also probably bring these languages that are spoken by the great majority of Europeans today.
  • Reich: Archaeology has always been political, especially in Europe. Archaeologists are very aware of the misuse of archaeology in the past, in the 20th century. There’s a very famous German archaeologist named Gustaf Kossinna, who was the first or one of the first to come up with the idea of “material culture.” Say, you see similar pots, and therefore you’re in a region where there was shared community and aspects of culture.
  • He went so far as to argue that when you see the spread of these pots, you’re actually seeing a spread of people and there’s a one-to-one mapping for those things. His ideas were used by the Nazis later, in propaganda, to argue that a particular group in Europe, the Aryans, expanded in all directions across Europe.
  • This was used to justify their expansionism in the propaganda that the Germans used in the run-up to the Second World War.
  • When you see these replacements of Neanderthals by modern humans or Europeans and Africans substantially replacing Native Americans in the last 500 years or the people who built Stonehenge, who were obviously extraordinarily sophisticated, being replaced from these people from the continent, it doesn’t say something about the innate potential of these people. But it rather says something about the different immune systems or cultural mismatch.
  • one of the things the ancient DNA is showing is actually the Corded Ware culture does correspond coherently to a group of people. [Editor’s note: The Corded Ware made pottery with cord-like ornamentation and according to ancient DNA studies, they descended from steppe ancestry.] I think that was a very sensitive issue to some of our coauthors
  • Our results are actually almost diametrically opposite from what Kossina thought because these Corded Ware people come from the East, a place that Kossina would have despised as a source for them.
  • it is true that there’s big population movements, and so I think what the DNA is doing is it’s forcing the hand of this discussion in archaeology, showing that in fact, major movements of people do occur. They are sometimes sharp and dramatic, and they involve large-scale population replacements over a relatively short period of time. We now can see that for the first time.
  • Zhang: As you say, the genetics data is now often ahead of the archaeology, and you keep finding these big, dramatic population replacements throughout human history that can’t yet be fully explained. How should we be thinking about these population replacements? Is there a danger in people interpreting or misinterpreting them as the result of one group’s superiority over another?
  • So after the Second World War, there was a very strong reaction in the European archaeological community—not just the Germans, but the broad continental European archaeological community—to the fact that their discipline had been used for these terrible political ends. And there was a retreat from the ideas of Kossinna.
  • Zhang: On the point of immune systems, one of the hypotheses for why people from the steppe were so successful in spreading through Europe is that they brought the bubonic plague with them. Since the plague is endemic to Central Asia, they may have built up immunity but the European farmers they encountered had not.
  • ut there have been profound and Earth-shattering events, again and again, every few thousand years in our history and that’s what ancient DNA is telling us.
  • if you actually take any serious look at this data, it just confounds every stereotype. It’s revealing that the differences among populations we see today are actually only a few thousand years old at most and that everybody is mixed.
  • I think that if you pay any attention to this world, and have any degree of seriousness, then you can’t come out feeling affirmed in the racist view of the world. You have to be more open to immigration. You have to be more open to the mixing of different peoples. That’s your own history.

What Is the U.S. Visa System for 'Skilled' Migrants? - The Atlantic - 0 views

  • The H-1B visa in particular, both its supporters and detractors argue, desperately needs an overhaul. Yet competing interests and disagreement over what needs fixing mean that, even with Trump’s administration having put restricting immigration flows at the center of its agenda, change is far from guaranteed.
  • The H-1B is one of several visa categories that allow foreign citizens to work while in the United States. Designed in the early 1990s as a temporary program to fill labor-market needs in highly specialized fields, such visas are issued in low numbers each year: This year’s cap was 85,000 in a nation with a labor force that’s estimated to be about 163 million people.
  • The White House has become more selective about approving new H-1B applications and changed the rules governing renewals so that the process is no longer automatic, as in Mahoney-Steel’s case.
  • ...7 more annotations...
  • the administration is gradually making the program a little more restrictive overall. (This appears to have had little impact thus far on the number of people who have applied for H-1Bs—as Bloomberg Law noted, more than 201,000 people put in for the 85,000 visas issued this year, a 6 percent increase over the previous year’s figures.)
  • in the Immigration Act of 1990. That original legislation did two things: It expanded legal immigration by increasing the number of green cards awarded each year, and it updated a 1950s-era program for temporary workers of “distinguished merit and ability” by capping the number who could obtain the visa at 65,000. (The cap has varied over the years.) This new program, the H-1B, was designed for skilled, temporary workers in certain occupations.
  • what came next: the global tech boom and the birth of the outsourcing industry. Suddenly, what had begun as a temporary solution to address a labor shortage became a device through which hundreds of thousands of IT professionals from around the world, especially India, came to the United States. The program became a de facto path to permanent residence and, ultimately, American citizenship.
  • Ron Hira, an associate professor of public policy at Howard University in Washington, D.C., who studies the impact of the visa, says the H-1B prioritizes outsourcers, sets wages too low, and doesn’t address the problem it was created to solve—filling labor-market gaps.“The program has been flawed from the inception,” he told me. “My primary complaint is that it’s used for cheap indentured workers.”
  • cation process is expensive, costing upwards of $2,400 (not counting lawyer’s fees), and has become cumbersome, they argue, so no American company would voluntarily seek to hire a foreign worker when simply hiring an American one is far easier.
  • Previous administrations tried to walk the line between these competing interests, but the Trump administration, through its actions, is making the H-1B far more difficult to get—especially for Indian software companies, whose visa applications were rejected in record numbers last year.
  • all of the changes so far to the existing system have introduced an atmosphere of uncertainty for people like Mahoney-Steel. Johns Hopkins decided not to seek to renew her visa. She told me that her supervisors were trying to rewrite her job description, but that the position she occupied was deemed by her employers too generic to be a specialized skill.

The Secret 'White Trains' That Carried Nuclear Weapons Around the U.S. - HISTORY - 0 views

  • Since the 1950s, this team of federal agents, most of them ex-military, has been tasked with ferrying America’s 6,800 nuclear warheads and extensive supply of nuclear materials across the roads and highways of the United States. America’s nuclear facilities are spread out throughout the country, on over 2.4 million acres of federal real estate, overseen by the Department of Energy (DOE)—a labyrinth of a system the Bulletin of the Atomic Scientists called “highly scattered and fragmented…with few enforceable rules.”
  • For as long as the United States has had nuclear weapons, it has struggled with the question of how to transport America’s most destructive technology throughout the country without incident. “It’s the weak link in the chain of nuclear security,” said Dr. Edwin Lyman of the Union of Concerned Scientists.
  • Today the United States relies almost entirely on million-dollar, Lockheed Martin tractor-trailers, known as Safeguard Transporters (SGTs) and Safe Secure Trailers (SSTs) to move nuclear material. But from the 1950s through the 1980s, the great hope for safe transit was so-called “white trains.”  
  • ...6 more annotations...
  • Amarillo was the final destination for almost all of America’s nuclear trains and the Pantex Plant was the nation’s only assembly point for nuclear weapons, a role it maintains to this day.
  • Each day trucks and trains rolled in, carrying plutonium from Georgia and Washington, bomb triggers from Colorado, uranium from Tennessee and neutron generators from Florida. They rolled out on white trains, carrying fully assembled nuclear weapons.
  • They then contacted peace and religious groups on the route, asking them to watch for the train, to organize a prayer vigil or a nonviolent protest when the train appeared, and to inform local newspapers about the train’s arrival.
  • But as the network of anti-nuclear activists grew, they became increasingly adept at tipping off the community if they saw an unmarked white train plow down their railways. They agency proposed new regulations that would make it illegal to pass information about the routing of the white train, but got little traction.
  • Though a group of protesters had effectively brought down the white trains, officials appeared confident that the nation’s rail network could provide an effective means of hiding weapons. By the late 1980s, the United States had 120,000 miles of available track, 20,000 locomotives, and 1.2 million railcars. At any given time, there were more than 1,700 trains on the tracks; military representatives insisted this would make it almost impossible for the Soviets to track where in the U.S. these 50 missile-laden trains had gone. “Rail-garrison will be the mainstay of our strategic defense well into the 21st century,” predicted one Texas Senator.
  • Whether waste or weapons, trains or trucks, the United States has been remarkably fortunate in avoiding major transportation mishaps. Since the days of the white trains, the government has insisted that nuclear materials are being moved across the American landscape in the safest possible way, persisting through crashes, fires, and interfering nuns. Yet public fears endure about whether moving such materials can ever truly be “safe.”

This man ate 'expired' food for a year. Here's why expiration dates are practically mea... - 0 views

  • It turns out that the dates on our food labels do not have much to do with food safety. In many cases, expiration dates do not indicate when the food stops being safe to eat — rather, they tell you when the manufacturer thinks that product will stop looking and tasting its best
  • Some foods, such as deli meats, unpasteurized milk and cheese, and prepared foods such as potato salad that you do not reheat, probably should be tossed after their use-by dates for safety reasons.
  • 84 percent of consumers at least occasionally throw out food because it is close to or past its package date, and over one third (37 percent) say they always or usually do so
  • ...7 more annotations...
  • That food waste in landfills generates carbon dioxide and methane, a greenhouse gas 28 to 36 times more effective at trapping heat in the atmosphere than carbon dioxide
  • you are not just wasting calories and money. You are wasting all the resources that went into growing, packaging and transporting that food.
  • The FDA, researchers and the grocery manufacturing industry largely agree on an initial solution to this particular part of the food waste problem: clearer package-date labels.
  • In 2017, the grocery industry, led by the Grocery Manufacturers Association and the Food Marketing Institute, announced a voluntary standard on food-date labeling. They narrowed the plethora of date-label terms down to two: “best if used by” and “use by.” “Best if used by” describes product quality, meaning the product might not taste as good past the date but is safe to eat. “Use by” is for products that are highly perishable and should be used or tossed by that date

What if Being a YouTube Celebrity Is Actually Backbreaking Work? - The New York Times - 0 views

  • It’s been two years. Chamberlain now has 8 million YouTube followers. She brought in the editing tricks that first set her friends and family rolling on the floor, but now they take longer to perfect.
  • Chamberlain edits each video she makes for between 20 and 30 hours, often at stretches of 10 or 15 hours at a time. Her goal is to be funny, to keep people watching. It’s as if the comic value of each video is inversely proportional to how little humor she experiences while making it. During her marathon editing sessions, she said, she laughs for “maybe, maybe 10 seconds max.”
  • Like other professional social media users, the work has taken a physical toll on her. (She releases roughly one video a week.) She used to edit at a desktop, but she developed back pain. Now she works from her bed. She keeps blue mood lighting on, but her vision has deteriorated. She wears reading glasses “like I’m 85 years old, because my eyes do actually get really strained.”

  • “It’s almost like when you’re doing your homework, you’re halfway through a math work sheet, you’re really in it right there. You can’t hear anything, you can’t see anything,” she said. “Or if you’re watching a movie and you’re so zoned in you don’t even remember what real life is. You just think you’re in the movie. That’s exactly how it is, but times five. I’m so zoned in. I have this weird mind-set where it’s me quickly analyzing every five seconds, ‘Is this boring, is this stupid, can I cut this? Yes. No. Yes. No. Yes. No.’”
  • Over these two years, Chamberlain invented the way people talk on YouTube now, particularly the way they communicate authenticity. Her editing tricks and her mannerisms are ubiquitous. There is an entire subgenre of videos that mimic her style, and a host of YouTubers who talk, or edit, just like her. The Atlantic recently noted this and declared she is “the most important YouTuber” working today.
  • I created this kind of style that was super cool to me and super exciting for me, and now that other people are doing it, now all of a sudden I’m unoriginal, which is something that I’ve always really tried to be. That’s what makes me feel good creatively. So when people started to say that, I kind of had a full, you know, not like mental breakdown, but we could also say that. Not a mental breakdown! But I definitely freaked out.”
  • Chamberlain’s parents have supported her unconventional choices, like dropping out of school in the beginning of her junior year and moving to Los Angeles to live by herself while still a teenager. She says that they were and are her best friends.
  • In June 2018, Chamberlain left the Bay Area to live alone in L.A. and fully immerse herself in YouTubeland.
  • Professional YouTubers are the children of reality television. The dramas of their videos are often inextricable from their lives. When Jake Paul and Tana Mongeau, two famous YouTubers, said they were engaged last month, it was impossible for fans to parse whether they were telling the truth. It barely mattered
  • YouTubers tend to bond and/or feud with one another constantly, because this is social media as much as it is performance art. They recreate the overheated dynamics of the high school environment that Chamberlain wanted to escape.
  • Chamberlain has now decided upon a new approach. “I’m just going to not stick to one thing so strictly,” she said.Her recent videos are less jittery, less edited. She has been trying to let her narrative and her scripts speak, with fewer interruptions than before.
  • Recently, she has tried anthologies and also stunts, like spending 24 hours on the balcony of her house
  • “I’m trying to make the stuff that I’m filming more dynamic so that when I’m editing there’s less pressure on me to kind of create something that’s not there,”
  • I’m starting to realize that editing is very personal, and 90 percent of the editing is just so that I’m not bored. So I don’t have to overdo it. I’m trying to find that balance right now, so that I don’t overwork myself

Not so, Revelle discovered; the peculiar chemistry of sea water actually prevents this from happening. Now, he said, humans have begun a “vast geophysical experiment.” We were about to burn, within a few generations, the fossil fuels that had slowly accumulated in the earth over the past 500 million years. Burning so much oil, gas, and coal would release massive amounts of carbon dioxide into the atmosphere, where it would trap heat that otherwise would escape into space. Earth’s temperature could rise, causing polar ice to melt and sea levels to rise, flooding the earth’s coastal regions.

  • Revelle and his colleagues got the green light, and by the fall of 1965 they produced the first official report to any government anywhere on the possible threat to humanity from rising CO2 levels. On November 6, Lyndon Johnson became the first president to mention the threat in a message to Congress.
  • Our own global-warming “phony war” is over. The hot war is here.
  • But we failed the moment. One year later, largely preoccupied with the war in Vietnam, the president grew distracted, budgets for other priorities were squeezed, and the nation was fast polarizing. We flunked that first chance to confront global warming
  • the powers in New York resisted. Through the rest of 1939 and into the spring of 1940, Hitler hunched on the borders of France and the Low Countries, his Panzers idling, poised to strike. Shirer fumed, “My God! Here was the old continent on the brink of war…and the network was most reluctant to provide five minutes a day from here to report it.” Just as the networks and cable channels provide practically no coverage today of global warming.

(You can go online to “Restoring the Quality of Our Environment—1965,” and read the entire 23-page section, headlined Appendix Y4—Atmospheric Carbon Dioxide.)
  • The networks put their reporters out in raincoats or standing behind police barriers as flames consume far hills. Yet we rarely hear the words “global warming” or “climate disruption” in their reports. The big backstory of rising CO2 levels, escalating drought, collateral damage, cause and effect, and politicians on the take from fossil-fuel companies? Forget all that. Not good for ratings, say network executives
  • But last October, the UN Intergovernmental Panel on Climate Change, a scientifically conservative body, gave us 12 years to make massive changes to reduce global greenhouse-gas emissions 45 percent below 2010 levels and to net zero by 2050
  • On his indispensable site, TomDispatch.com, Tom Engelhardt writes that humanity is now on a suicide watch.
  • Here’s the good news: While describing David Wallace-Wells’s stunning new book The Uninhabitable Earth as a remorseless, near-unbearable account of what we are doing to our planet, The New York Times reports it also offers hope. Wallace-Wells says that “We have all the tools we need…to aggressively phase out dirty energy…; [cut] global emissions…[and] scrub carbon from the atmosphere…. [There are] ‘obvious’ and ‘available,’ [if costly,] solutions.” What we need, he adds, is the “acceptance of responsibility.”
  • Late 1940. The start of the Blitz, with bombs blasting London to bits. A Gallup poll that September found that a mere 16 percent of Americans supported sending US aid to beleaguered Britain. Olson and Cloud tell us that “One month later, as bombs fell on London, and Murrow and the Boys brought the reality of it into American living rooms, 52 percent thought more aid should be sent.”
  • With no silver bullet, what do we do? We cooperate as kindred spirits on a mission of public service. We create partnerships to share resources. We challenge media owners and investors to act in the public interest. We keep the whole picture in our heads—how melting ice sheets in the Arctic can create devastation in the Midwest—and connect the dots for our readers, viewers, and listeners

The Coming Software Apocalypse - The Atlantic - 0 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.”
  • 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.”

  • 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.
  • “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.”
  • What made programming so difficult was that it required you to think like a computer.
  • 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.
  • “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.
  • 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.

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.
  • 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,
  • WYSIWYG (pronounced “wizzywig”) came along. It stood for “What You See Is What You Get.”
  • “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.”
  • 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.
  • 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.
  • . 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.
  • 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.”
  • “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.”
  • 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.
  • 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
  • “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.”
  • 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.”
  • 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.
  • 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.
  • In the world of the self-driving car, software can’t be an afterthought. It can’t be built like today’s airline-reservation systems or 911 systems or stock-trading systems. Code will be put in charge of hundreds of millions of lives on the road and it has to work. That is no small task.

Invention of Paper | Chinese Inventions - 0 views

  • According to ancient Chinese historical sources, a court eunuch named Ts'ai Lun (or Cai Lun) presented newly-invented paper to the Emperor Hedi of the Eastern Han Dynasty in 105 CE.
  • The historian Fan Hua (398-445 CE) recorded this version of events, but archaeological finds from western China and Tibet suggest that paper was invented centuries earlier.
  • proving that ink too was invented much earlier than historians had supposed.

  • bark, silk, wood and leather functioned in a similar way to paper, although they were either much more expensive or heavier. In China, many early works were recorded on long bamboo strips, which were then bound with leather straps or string into books.
  • People world-wide also carved very important notations into stone or bone, or pressed stamps into wet clay and then dried or fired the tablets to preserve their words. However, writing (and later printing) required a material that was both cheap and lightweight in order to become truly ubiquitous. Paper fit the bill perfectly.
  • Early paper-makers in China used hemp fibers, which were soaked in water and pounded with a large wooden mallet. The resulting slurry was then poured over a horizontal mold; loosely-woven cloth stretched over a framework of bamboo allowed the water to drip out the bottom or evaporate, leaving behind a flat sheet of dry hemp-fiber paper.
  • One of the most common formats for early paper was the scroll. A few long pieces of paper were pasted together to form a strip, which was then wrapped around a wooden roller. The other end of the paper was attached to a thin wooden dowel, with a piece of silk cord in the middle to tie the scroll shut.
  • From its point of origin in China, the idea and technology of paper-making spread throughout Asia.
  • The Koreans also used rice straw and seaweed, expanding the types of fiber available for paper production. This early adoption of paper fueled the Korean innovations in printing, as well; metal movable type was invented by 1234 CE on the peninsula.
  • One of the most interesting repercussions of this Arab victory was that the Abbasids captured Chinese artisans - including master paper-makers like Tou Houan - and took them back to the Middle East.
  • so knowledge of this marvelous new material spread far and wide. Before long, cities from Samarkand (now in Uzbekistan) to Damascus and Cairo had become centers of paper production.
  • In 1120, the Moors established Europe's first paper mill at Valencia, Spain (then called Xativa). From there, this Chinese invention passed to Italy, Germany, and other parts of Europe. Paper helped spread knowledge, much of which was gleaned from the great Asian culture centers along the Silk Road, that enabled Europe's High Middle Ages.
  •  
    This shows where paper was made and how it spread from China to Europe. It is intresting being able to trace something that helped with the European High Middle Ages to its origin so far away.

Opinion | How Not to Panic About Inflation - The New York Times - 0 views

  • After the 2008 financial crisis plunged America into a deep recession, both the new Obama administration and the Federal Reserve tried to stimulate the economy, spending hundreds of billions on a variety of programs while buying trillions in bonds. There is now consensus among economists that these efforts were helpful, but it’s also widely believed that they were inadequate (as some of us strenuously argued at the time).
  • Reflecting this expectation, companies will mark prices up relative to what they would have been if they didn’t expect future inflation — and by so doing, will feed the very inflation they fear. In other words, once expectations of sustained inflation are embedded in the economy, inflation becomes self-perpetuating — and bringing it down can be extremely difficult. That’s what makes stagflation — inflation despite high unemployment — possible.
  • If they aren’t — and my bet is that they won’t be — then the lesson of 2010-2011 will remain: Don’t panic.Now as then there are people eager to denounce government attempts to help the economy. And it’s certainly possible that the American Rescue Plan will turn out, in retrospect, to have been too much of a good thing. But don’t let the usual suspects seize on a few months’ inflation data as evidence of looming disaster.
