Megan Garber writes about some of our earliest forays into lighting our cities with giant "moon-towers" which imitated luna, err, lumination:
During the hot summer of 1882, the installation of the new moon towers became its own kind of brilliant spectacle. People gathered to witness the building of structures that represented Progress and Ingenuity and, in a very real sense, The Future. They also gathered to witness some drama. Since electrical engineers were just learning their trade -- that trade, in Detroit's case, being the erection of 150-foot-tall poles anchoring 500 pounds worth of lights -- accidents were, perhaps, inevitable. And falling towers -- thin metal, plus gravity -- had an uncanny way of slicing through roofs as they toppled toward the ground.
The light itself, though, was the true attraction. It was, as Brush had guaranteed, "picturesque and romantic," one observer put it. Within the glow of the manmade moons, "the foliage is weird and beautiful. All places within the scope of light are bathed in the faint but fairy-like illumination of the moon in its first-quarter."
But not all of the crowds were excited about the new buildings studding their town's landscape. On the contrary, "many Detroiters," Freeberg writes, "were skeptical from the start." Some found the towers to be eyesores, each structure braced with a chaotic network of wires and posts. (One man even tried to chop down the wires that hung near his home, an act of civic-cosmetic rebellion for which he was arrested.) The lights also brought unanticipated complications along with their steady illumination. Animals, for one thing, were unaccustomed to the newly extended daytime. Chickens and geese, unable to sleep in this new state of omnipresent light, began to die of exhaustion.
Humans, too, found the high-slung orbs to be as disorienting as they were ethereal. As tall as the towers were, they still left shadows in their wake -- shadows tinged with sharp blue light, Freeberg notes, which left pedestrians "dazed and puzzled." Foggy evenings, combined with the air pollution of a newly industrialized America, could thrust all of Detroit into effective darkness -- meaning, Freeberg writes, that "Detroiters could only speculate about the lovely sight that their lights must be creating as they shone down on the blanket of mist and soot that smothered the city." Even during occasions when the fog broke enough to allow some light to penetrate to the streets below, "many found themselves groping along sidewalks in an eerie gloom."
I think it was Cynic who once described The Atlantic's Tech channel as half-tech and half-history. I often think that technology is under-appreciated in understanding the advance of civil rights. In the 1860s, Northern soldiers advancing into the South were shocked to see slavery was as bad as abolitionists said it was. One hundred years, Northern whites could see that Bull Connor was every bit as bad as civil rights workers said it was, right from their own couches.
At any rate, I love the historical approach to technology. When I finished reading this, I couldn't quite get Tesla out of my head.
A new anatomical understanding of how movement controls the body’s stress response system
Elite tennis players have an uncanny ability to clear their heads after making errors. They constantly move on and start fresh for the next point. They can’t afford to dwell on mistakes.
Peter Strick is not a professional tennis player. He’s a distinguished professor and chair of the department of neurobiology at the University of Pittsburgh Brain Institute. He’s the sort of person to dwell on mistakes, however small.
“My kids would tell me, dad, you ought to take up pilates. Do some yoga,” he said. “But I’d say, as far as I’m concerned, there's no scientific evidence that this is going to help me.”
Still, the meticulous skeptic espoused more of a tennis approach to dealing with stressful situations: Just teach yourself to move on. Of course there is evidence that ties practicing yoga to good health, but not the sort that convinced Strick. Studies show correlations between the two, but he needed a physiological mechanism to explain the relationship. Vague conjecture that yoga “decreases stress” wasn’t sufficient. How? Simply by distracting the mind?
City dwellers spend nearly every moment of every day awash in wi-fi signals. Homes, streets, businesses, and office buildings are constantly blasting wireless signals every which way for the benefit of nearby phones, tablets, laptops, wearables, and other connected paraphernalia.
When those devices connect to a router, they send requests for information—a weather forecast, the latest sports scores, a news article—and, in turn, receive that data, all over the air. As it communicates with the devices, the router is also gathering information about how its signals are traveling through the air, and whether they’re being disrupted by obstacles or interference. With that data, the router can make small adjustments to communicate more reliably with the devices it’s connected to.
No one will ever find a closer exoplanet—now the race is on to see if there is life on its surface.
One hundred and one years ago this October, a Scottish astronomer named Robert Innes pointed a camera at a grouping of stars near the Southern Cross, the defining feature of the night skies above his adopted Johannesburg. He was looking for a small companion to Alpha Centauri, our closest neighboring star system.
Hunched over glass photographic plates, Innes teased out a signal. Across five years of images, a small, faint star moved, wiggling on the sky. It shifted just as much as Alpha Centauri, suggesting its fate was intertwined with that binary system. But this small star was closer to the sun than Alpha. Innes suggested calling it Proxima Centauri, using the Latin word for “nearest.”
The dim red star soon entered the collective imagination, inspiring dreams of interstellar travel. Gravity has linked the star to the Alpha Centauri system, but our culture of science and storytelling has linked it to the solar system. Today, that link will grow stronger, when an international team of astronomers announces that this nearest of stars also hosts the closest exoplanet, one that might look a whole lot like Earth.
Do mission-driven organizations with tight budgets have any choice but to demand long, unpaid hours of their staffs?
Earlier this year, at the encouragement of President Obama, the Department of Labor finalized the most significant update to the federal rules on overtime in decades. The new rules will more than double the salary threshold for guaranteed overtime pay, from about $23,000 to $47,476. Once the rules go into effect this December, millions of employees who make less than that will be guaranteed overtime pay under the law when they work more than 40 hours a week.
Unsurprisingly, some business lobbies and conservatives disparaged the rule as unduly burdensome. But pushback also came from what might have been an unexpected source: a progressive nonprofit called the U.S. Public Interest Research Group (PIRG). “Doubling the minimum salary to $47,476 is especially unrealistic for non-profit, cause-oriented organizations,” U.S. PIRG said in a statement. “[T]o cover higher staffing costs forced upon us under the rule, we will be forced to hire fewer staff and limit the hours those staff can work—all while the well-funded special interests that we're up against will simply spend more.”
This much is obvious: Young people don’t buy homes like they used to.
In the aftermath of the recession and weak recovery, the share of 18- to- 34 year olds—a.k.a.: Millennials—who own a home has fallen to a 30-year low. For the first time on record going back more than a century, young people are now more likely to live with their parents than with a spouse.
It’s become en vogue to argue that young people’s turn against homeownership might be a good thing. After all, houses are not always dependable investment vehicles, a lesson the country learned all too painfully after the Great Recession. Without being anchored to any one city from their mid-20s and into their 30s, young people who don’t own are free to roam about the country in search of the best jobs. What’s more, given the copious advantages of a college degree in this economy, perhaps many young people could be commended for investing in their intelligence, professional networks, and abilities rather than devote that same income to a roof, floor, and furniture.
A recent scholarly paper on “microaggressions” uses them to chart the ascendance of a new moral code in American life.
Last fall at Oberlin College, a talk held as part of Latino Heritage Month was scheduled on the same evening that intramural soccer games were held. As a result, soccer players communicated by email about their respective plans. “Hey, that talk looks pretty great,” a white student wrote to a Hispanic student, “but on the off chance you aren’t going or would rather play futbol instead the club team wants to go!!”
Unbeknownst to the white student, the Hispanic student was offended by the email. And her response signals the rise of a new moral culture America.
When conflicts occur, sociologists Bradley Campbell and Jason Manning observe in an insightful new scholarly paper, aggrieved parties can respond in any number of ways. In honor cultures like the Old West or the street gangs of West Side Story, they might engage in a duel or physical fight. In dignity cultures, like the ones that prevailed in Western countries during the 19th and 20th Centuries, “insults might provoke offense, but they no longer have the same importance as a way of establishing or destroying a reputation for bravery,” they write. “When intolerable conflicts do arise, dignity cultures prescribe direct but non-violent actions.”
In his 1945 article “The Economic Organisation of a P.O.W. Camp,” the British economist R.A. Radford recounted his experiences within the informal system of barter among prisoners at Stalag VII-A, a German camp on the outskirts of Munich during the Second World War. Using supplies delivered by the Red Cross, some prisoners moved between different nationalities’ encampments, buying tea for cheap from the French (who tended to prefer coffee) and then selling it to the British (whose affection for tea is a matter of centuries-old lore). Meanwhile, imprisoned Gurkha soldiers from South Asia sought out tins of vegetables and bartered them for corned beef.
Radford’s account, which was compellingly retold by Ray Fisman and Tim Sullivan in their recent book The Inner Lives of Markets, explains that, in the absence of paper money, prisoners had to pick another currency to enable their transactions: cigarettes. “A ration of margarine might be bought for seven cigarettes, the equivalent, for instance, of one and a half chocolate bars, and so on,” Fisman and Sullivan write. “For the most part, prices were well known and consistent among the camp’s many huts that acted as local markets.”
Polling within the margin of error among African Americans, the Republican tries new outreach—but his approach seems doomed to failure.
Although Donald Trump has long claimed to “have a great relationship with the blacks,” the polls tell a different story, with Trump frequently polling in the single digits among black voters. Over the last few days, the Republican nominee has added a new passage to his stump speech, reaching out to the African American community.
Our government has totally failed our African American friends, our Hispanic friends and the people of our country. Period. The Democrats have failed completely in the inner cities. For those hurting the most who have been failed and failed by their politicians—year after year, failure after failure, worse numbers after worse numbers. Poverty. Rejection. Horrible education. No housing, no homes, no ownership. Crime at levels that nobody has seen. You can go to war zones in countries that we are fighting and it's safer than living in some of our inner cities that are run by the Democrats. And I ask you this, I ask you this—crime, all of the problems—to the African Americans, who I employ so many, so many people, to the Hispanics, tremendous people: What the hell do you have to lose? Give me a chance. I'll straighten it out. I'll straighten it out. What do you have to lose?
Donald Trump’s campaign manager says he’s actually winning, thanks to “undercover” supporters. Plenty of past presidential hopefuls have mistakenly believed the same.
A candidate or operative on a campaign that's losing has three options: despair; accept what’s happening and try to fix it; or deny. Right now, the Donald Trump campaign is exhibiting all three.
For despair, there are the staffers who are reportedly “suicidal” inside Trump Tower, and those who have simply quit. For acceptance, Trump himself has admitted he’s in trouble. But newly promoted campaign manager Kellyanne Conway is taking the denial route.
“Donald Trump performs consistently better in online polling where a human being is not talking to another human being about what he or she may do in the election,” she told the British outlet Channel 4. “It’s because it’s become socially desirable, if you’re a college educated person in the United States of America, to say that you’re against Donald Trump.”
