Hot Students Learn Less

More evidence on why air conditioning increases our mental acuity:

(p. A5) Hot weather makes it more difficult for high-school students to learn, a new study suggests.
. . .
The study was circulated by the National Bureau of Economic Research as a working paper by Mr. Goodman and three other researchers.
They found that, on average, every increase of 1 degree Fahrenheit in the average temperature during the school year reduced learning by about 1%.

After Losing Circus Job, Clown Applies His Skills by Running for Congress as a Democrat

(p. A1) As an elephant handler for Ringling Bros. and Barnum & Bailey Circus, Lauren Ramsay used to spend her time herding four-ton pachyderms.
As an elephant handler for Ringling Bros. and Barnum & Bailey Circus, Lauren Ramsay used to spend her time herding four-ton pachyderms.
Last May, the circus closed down after 146 years traveling the country and thrilling millions with “the Greatest Show on Earth.” In the year since, the contortionists, acrobats, stilt walkers and other per-(p. A8)formers have walked a tightrope trying to adapt to more-conventional jobs, while sometimes using their circus skills. It takes some professional clowns a while to find a second act: One is now running for Congress.
Former clown Sandor Eke, of Las Vegas, Nev., wanted to put his entertaining and juggling skills to work behind a bar after 20 years with the circus. But nobody would hire him without experience. He’s now picking up random clown jobs and painting houses. “I try to have fun with it, but it’s not exactly what I wanted with life. I mean, I used to be a clown!”
In April, Mr. Eke auditioned for a mascot job with the Oakland Raiders once they move to Las Vegas for the 2020 season. He tried on the “Rushing Raider” costume, and did what he called a “crowd-pleasing routine.” He’s waiting to hear back, but remains hopeful. “I got good vibes,” he says.
. . .
Former clown Steve Lough, of Camden, S.C., who left the circus in 2004, later found employment working for McDonald’s at special events and volunteering for political campaigns.
This spring, Mr. Lough decided to run for office himself and is running in the Democratic primary for U.S. Congress in South Carolina. “I juggle at every campaign stop now,” he says.
He did a pratfall at the South Carolina Democratic Convention in April that “got a big reaction and laugh.”
. . .
. . . Mr. Lough says the crowds love his clown skills.

“Entrepreneurial Capitalism Takes More People Out of Poverty Than Aid”

(p. A15) Some 44% of millennials believe they do more to support social causes than the rest of their family, according to the 2017 Millennial Impact report. If you’re volunteering at shelters or working for most nonprofits, that’s all very nice, but it’s one-off. You’re one of the privileged few who have the education to create lasting change. It may feel good to ladle soup to the hungry, but you’re wasting valuable brain waves that could be spent ushering in a future in which no one is hungry to begin with.
There’s a word that was probably never mentioned by your professors: Scale. No, not the stuff on the bottom of your bong or bathtub. It’s the concept of taking a small idea and finding ways to implement it for thousands, or millions, or even billions. Without scale, ideas are no more than hot air. Stop doing the one-off two-step. It’s time to scale up.
. . .
If you don’t think I’m credible, you too can listen to Bono. As he told Georgetown students a few years ago, “Entrepreneurial capitalism takes more people out of poverty than aid.” Of course it does. Want to change the world? Stop doing one-off volunteering and scale up.

Stornetta and Nakamoto Invented Bitcoin

(p. C18) In 1990, the physicist Scott Stornetta had a eureka moment while getting ice cream with his family at a Friendly’s restaurant in Morristown, N.J. He and his cryptographer colleague, Stuart Haber, had been thinking about the proliferation of digital files that accompanied the rise of personal computing and the ease with which files could be altered. They wondered how we might know for certain what was true about the past. What would prevent tampering with the historical record–and would it be possible to protect such information for future generations?
The sticking point was the need to trust a central authority. But at Friendly’s, an answer came to Dr. Stornetta: He realized that instead of a central record-keeper, the system could have many dispersed but interconnected copies of a shared ledger. The truth could never be typed over if there were too many linked ledgers to alter.
Drs. Haber and Stornetta were working at the time at Bellcore, a research center descended from the legendary Bell Labs. The pair set out to build a cryptographically secure archive–a way to verify records without revealing their contents.
. . .
. . . there is no mistaking their crucial contribution. When the founding document of bitcoin was published in 2008 under the name ” Satoshi Nakamoto “–a pseudonym for one or more scientists–it had just eight citations of previous works. Three of them were papers co-authored by Drs. Haber and Stornetta.
, , ,
The Nakamoto paper revolutionized the foundational work of Drs. Stornetta and Haber by adding the concept of “mining” cryptocurrencies. It created financial incentives for participation in retaining and verifying parts of the blockchain ledger.

Trump’s Judges Constrain the Administrative State

(p. A1) WASHINGTON — It has been practically a given that anyone nominated for a federal judgeship by a Republican president had to pass an unspoken litmus test — usually on abortion but often on any number of divisive social issues.
The Trump administration has a new litmus test: reining in what conservatives call “the administrative state.”
With surprising frankness, the White House has laid out a plan to fill the courts with judges devoted to a legal doctrine that challenges the broad power federal agencies have to interpret laws and enforce regulations, often without being subject to judicial oversight. Those not on board with this agenda, the White House has said, are unlikely to be nominated by President Trump.
. . .
(p. A13) That the concept of “the administrative state” has become so central to politics today shows how successful the Trump administration has been in elevating to the mainstream ideas that once thrived mainly on the edges of conservative and libertarian thought.
A year ago it was a term known mostly among academics to describe the vast array of federal departments and the unelected functionaries who run them. It entered the mainstream political lexicon last year after the president’s former chief strategist, Stephen K. Bannon, pledged a “deconstruction of the administrative state” under Mr. Trump.
. . .
But this thinking has been advanced by many libertarian-minded conservatives who have long doubted whether the founders envisioned the creation of many New Deal and Great Society programs and the abundance of regulations that flowed from them.
“A lot of this, if you unpack it, I think it will get back to fundamental fairness,” said Mark Holden, general counsel for Koch Industries, which is led by Charles G. and David H. Koch, two of the biggest financial backers of the effort to elect office holders committed to deregulation and free-market enterprise.
The Trump judicial selection process, Mr. Holden added, was ultimately focused on “the size and scope of government and scaling it back, to the extent that it’s counterproductive and contrary to due process.”

“Infatuation with Deep Learning May Well Breed Myopia . . . Overinvestment . . . and Disillusionment”

(p. B1) For the past five years, the hottest thing in artificial intelligence has been a branch known as deep learning. The grandly named statistical technique, put simply, gives computers a way to learn by processing vast amounts of data.
. . .
But now some scientists are asking whether deep learning is really so deep after all.
In recent conversations, online comments and a few lengthy essays, a growing number of A.I. experts are warning that the infatuation with deep learning may well breed myopia and overinvestment now — and disillusionment later.
“There is no real intelligence there,” said Michael I. Jordan, a professor at the University of California, Berkeley, and the author of an essay published in April intended to temper the lofty expectations surrounding A.I. “And I think that trusting these brute force algorithms too much is a faith misplaced.”
The danger, some experts warn, is (p. B4) that A.I. will run into a technical wall and eventually face a popular backlash — a familiar pattern in artificial intelligence since that term was coined in the 1950s. With deep learning in particular, researchers said, the concerns are being fueled by the technology’s limits.
Deep learning algorithms train on a batch of related data — like pictures of human faces — and are then fed more and more data, which steadily improve the software’s pattern-matching accuracy. Although the technique has spawned successes, the results are largely confined to fields where those huge data sets are available and the tasks are well defined, like labeling images or translating speech to text.
The technology struggles in the more open terrains of intelligence — that is, meaning, reasoning and common-sense knowledge. While deep learning software can instantly identify millions of words, it has no understanding of a concept like “justice,” “democracy” or “meddling.”
Researchers have shown that deep learning can be easily fooled. Scramble a relative handful of pixels, and the technology can mistake a turtle for a rifle or a parking sign for a refrigerator.
In a widely read article published early this year on arXiv.org, a site for scientific papers, Gary Marcus, a professor at New York University, posed the question: “Is deep learning approaching a wall?” He wrote, “As is so often the case, the patterns extracted by deep learning are more superficial than they initially appear.”

We Underestimate How Entrepreneurial the Americans Were in the 1800s

(p. C6) Jim DeFelice’s “West Like Lightning,” a history of the Pony Express, begins with an anxious young rider waiting to take the news to California that Abraham Lincoln had been elected president. The delivery service lasted only about 18 months, but its revolutionary speed left an indelible mark on the country. Many, including Mark Twain, marveled at riders’ courage and the spectacle of their switching horses every 10 miles or so for a fresh burst of speed.
. . .
In what way is the book you wrote different from the book you set out to write?
Historians, God bless them, they do a lot of debunking of legends. They can sometimes come off as schoolmarms. The reality is, those legends are fun. They’re the exciting part. I separate fact and fiction, but I love those stories — and underneath them, there’s a much deeper truth. There’s a reason we value these 19- and 20-year-old kids pushing themselves against the elements.
I knew there would be some debunking involved. What I didn’t know was how true a lot of those stories turned out to be. If I were a Pony Express rider, I’d be bragging about how fast I made it. These guys didn’t brag about that — they bragged about how far they went. They were bragging about endurance and dealing with the elements. That impressed me, the resilience.
I also think sometimes we underestimate — and I’m guilty of this — just how entrepreneurial and into technology people were in the past. We think we’re cool because we can fly somewhere and be there tomorrow. But for these guys, 10 days was huge. If you gave them something in downtown New York, it would be in San Francisco two weeks later. At the time, that would be like going from dial-up to the fastest speeds we have today.

Fewer Summer Jobs Filled by Teenagers

(p. D8) You can still find high school and college students boiling hot dogs and cleaning the fryer at the clam shacks, country clubs and state fairs that spring to life when the weather turns hot. But the food that fuels a summer vacation is now more likely being prepared by temporary workers from other countries or local adults trying to make the gig economy work for them.
. . .
Although youth employment in the United States still spikes in the warmer months, the number of teenagers in the summer labor force fell to 43 percent in 2016, from almost 72 percent at its peak in 1978, according to the most recent figures from the federal Bureau of Labor Statistics.
Pressure has come from several directions. School started stretching into summer. Employment laws became more restrictive. Scooping cones or running a dough-filled Hobart were no longer considered worthy résumé builders.
At the same time, demand for summer workers rose.

“Some Things Are True Even if Donald Trump Believes Them!”

(p. A21) One of the hardest things to accept for all of us who want Donald Trump to be a one-term president is the fact that some things are true even if Donald Trump believes them! And one of those things is that we have a real trade problem with China. Imports of Chinese goods alone equal two-thirds of the global U.S. trade deficit today.
. . .
. . . , I sat down with David Autor, the M.I.T. economist who’s done some of the most compelling research on the impacts of China trade. The first problem he raised has to do with the “shock” that China delivered to U.S. lower-tech manufacturers in the years right after Beijing joined the World Trade Organization in 2001, when it gained more open access to the U.S. and other world markets.
. . .
Autor and his colleagues David Dorn and Gordon Hanson found in a 2016 study that roughly 40 percent of the decline in U.S. manufacturing between 2000 and 2007 was due to a surge in imports from China primarily after it joined the W.T.O. And it led to the sudden loss of about one million factory jobs in Ohio, Michigan, Wisconsin and Pennsylvania. Trump won all of those states.
This “China shock,” said Autor, led not only to mass unemployment but also to social disintegration, less marriage, more opioid abuse and more people dropping out of the labor market and requiring government aid. “International trade creates diffuse benefits and concentrated costs,” he added. “China’s rapid rise, while enormously positive for world welfare, has created identifiable losers in trade-impacted industries and the labor markets in which they are located.”
The second problem has to do with access to China’s market for the goods U.S. companies sell. There, noted Autor, “China has not only taken our lunch, they’ve opened a restaurant that’s serving it to their citizens.”
. . . China kept a 25 percent tariff on new cars imported from the U.S. (our tariff is 2.5 percent) and similarly steep tariffs on imported auto parts.

Wages Rise as Fast-Food Jobs Go Unfilled

(p. A10) . . . in an industry where cheap labor is an essential component in providing inexpensive food, a shortage of workers is changing the equation upon which fast-food places have long relied. This can be seen in rising wages, in a growth of incentives, and in the sometimes odd situations that business owners find themselves in.
This is why Jeffrey Kaplow, for example, spends a lot of time working behind the counter in his Subway restaurant in Lower Manhattan. It’s not what he pictured himself doing, but he simply doesn’t have enough employees.
Mr. Kaplow has tried everything he can think of to find workers, placing Craigslist ads, asking other franchisees for referrals, seeking to hire people from Subways that have closed.

Silicon Valley Venture Capitalists “Fantasize about Relocating” to “Detroit and South Bend”

(p. B1) It was pitched as a kind of Rust Belt safari — a chance for Silicon Valley investors to meet local officials and look for promising start-ups in overlooked areas of the country.
But a funny thing happened: By the end of the tour, the coastal elites had caught the heartland bug. Several used Zillow, the real estate app, to gawk at the availability of cheap homes in cities like Detroit and South Bend and fantasize about relocating there. They marveled at how even old-line manufacturing cities now offer a convincing simulacrum of coastal life, complete with artisanal soap stores and farm-to-table restaurants.
. . .
(p. B4) Mr. McKenna, who owns a house in Miami in addition to his home in San Francisco, told me that his travels outside the Bay Area had opened his eyes to a world beyond the tech bubble.
“Every single person in San Francisco is talking about the same things, whether it’s ‘I hate Trump’ or ‘I’m going to do blockchain and Bitcoin,'” he said. “It’s the worst part of the social network.”
. . .
Recently, Peter Thiel, the President Trump-supporting billionaire investor and Facebook board member, became Silicon Valley’s highest-profile defector when he reportedly told people close to him that he was moving to Los Angeles full-time, and relocating his personal investment funds there. (Founders Fund and Mithril Capital, two other firms started by Mr. Thiel, will remain in the Bay Area.) Mr. Thiel reportedly considered San Francisco’s progressive culture “toxic,” and sought out a city with more intellectual diversity.
Mr. Thiel’s criticisms were echoed by Michael Moritz, the billionaire founder of Sequoia Capital. In a recent Financial Times op-ed, Mr. Moritz argued that Silicon Valley had become slow and spoiled by its success, and that “soul-sapping discussions” about politics and social injustice had distracted tech companies from the work of innovation.
Complaints about Silicon Valley insularity are as old as the Valley itself. Jim Clark, the co-founder of Netscape, famously decamped for Florida during the first dot-com era, complaining about high taxes and expensive real estate. Steve Case, the founder of AOL, has pledged to invest mostly in start-ups outside the Bay Area, saying that “we’ve probably hit peak Silicon Valley.”
. . .
This isn’t a full-blown exodus yet. But in the last three months of 2017, San Francisco lost more residents to outward migration than any other city in the country, according to data from Redfin, the real estate website. A recent survey by Edelman, the public relations firm, found that 49 percent of Bay Area residents, and 58 percent of Bay Area millennials, were considering moving away. And a sharp increase in people moving out of the Bay Area has led to a shortage of moving vans. (According to local news reports, renting a U-Haul for a one-way trip from San Jose to Las Vegas now costs roughly $2,000, compared with just $100 for a truck going the other direction.)
