We hear a lot about energy research and development. Perhaps that's because it's the one sort of policy that Republicans and Democrats generally agree on. But there's a different kind of research that I'd like to see get a lot more attention and funding. I'm talking about research into what various kinds of energy policies actually *do* to shape the technical possibilities open to humanity.
In my time researching energy, most of the people who actually care about where we get our energy from have committed to an energy source, be it oil, gas, traditional nuclear, wind, solar, geothermal, or thorium. Then, they go looking for policies that would benefit their technology. I've also run into a lot of people who believe in inexorable laws of change in energy, whether that's decarbonization or the inevitable rise of natural gas or nuclear power. And I've run into a lot of energy experts who believe in a fairly simple relationship between research money going in and technologies coming out.
Unfortunately, none of these three groups of people is likely to produce very good energy policy. To put it in more mainstream terms, we've got a lot of energy pundits and very few energy Nate Silvers, who put reality (i.e. good data) ahead of ideology and intuition. Don't get me wrong: everyone in energy loves them some data, but few people are interested in using it the way Silver does.
Let me introduce you to a scholar who I think embodies the kind of research we need more of. His name is Gregory Nemet. He did his PhD at Berkeley and now teaches at the University of Wisconsin, Madison. I first discovered his work through a 2006 paper in Energy Policy, "Beyond the Learning Curve: factors influencing cost reductions in photovoltaics." Now, you're probably familiar with the neat story that learning curves tell. They say that as you do something, you get better at it, and because it's a curve, the assumption is that this happens at a fairly consistent (and therefore predictable) rate. This is part of the rationale for supporting photovoltaics after all. They've gotten so much cheaper (orders of magnitude) over the last few decades that proponents suggest they're inevitably going to get cheaper than grid electricity some time in the near future.
But this is just too simple a model for the way the world works. Nemet first demolishes the idea that we can bank on simple learning by experience models that show consistent cost reductions as the amount of solar produced increases. These analyses are super sensitive to small changes in the learning rate or the growth of the market (the number of megawatts of PV production in a given time span). And that's not even taking into account the discontinuities that we know occur in technological development. He raises several other powerful objections based on the literature. All in all, it's a pretty amazing takedown of a common method of analysis.
But he doesn't stop there. He then uses the history of photovoltaics (from 1976-2001) to demonstrate a new way of modeling cost reductions in technology. It's hard to gloss the whole thing, but suffice to say that his model allows him to identify which of the following factors were important for different periods of the technology's evolution in driving down cost: plant size, scaling factor, module efficiency, silicon cost, wafer size, silicon use, yield, polycrystal share, polycrystal cost.
With kind of policy impact might that have? Well, if increasing the size of photovoltaic plants appears to lead to large cost reductions, then it might be a good idea to have a loan program that helps get these sorts of plants built. A loan program much like the one that produced many good outcomes along with a few duds like Solyndra.
But there's a deeper reason to support this kind of research. When people think of technological development as somehow magically proceeding apace, it makes it seem *as if* people's personal and civic interventions don't matter. But of course they do! It's just that when you draw one curve to stick in your PowerPoint, all the decisions that affect the factors above get submerged into a false law of simplistic cost reductions.
Since 2006, Nemet has kept working on important research projects. He's done more work on trying to model the effectiveness of differing government support models, as in this paper on whether subsidies or R&D spending are more likely to bring organic solar cells to market. (In this case, the answer is R&D.)
His most recent work, though, might be his most significant, though I think his current research program is not yet complete. In carious ways, he's been trying to get at a very basic question: do demand-side subsidies work to stimulate technological development? Or might better policies exist? This is more than a theoretical question, given the various tax credits both here and abroad that appear to have pushed low-carbon technologies forward. Note the way I framed his project, which I think he would agree with. This is not about whether Nemet believes government should be subsidizing energy projects or not. This is not about whether solar or wind or nuclear *should* be the future of our energy system. No, this is something more basic and more difficult to answer: how much can subsidies enhance the learning (and therefore cost reductions) that an industry like wind actually does?
If you're curious what his final analysis is, here's the conclusion from an excellent forthcoming paper in the Journal of Policy Analysis and Management. You probably won't be surprised to learn that he makes a nuanced judgment:
The magnitude of public funds at stake add some urgency to improving understanding of the extent and characteristics of knowledge spillovers from learning by doing. The main results here imply that policies that enhance demand are necessary to generate sufficient knowledge from experience. Other insights from this case--especially depreciation and diminishing returns--heighten the value of policy instruments with performance-oriented mechanisms and longevity. That experience-derived knowledge appears to be so ephemeral suggests that we should also consider explicit support for codification and transfer of what is learned.
In an NPR interview, the Pretenders singer compared comments about her book—and its description of her sexual assault—to a “lynch mob.”
In maybe one of the most uncomfortable NPR interviews since Joaquin Phoenix went on Fresh Air, the Pretenders singer Chrissie Hynde spoke with Morning Edition’s David Greene on Tuesday about her book, Reckless. Or, more specifically, about the mass outrage sparked by the section in which she writes about being sexually assaulted at the age of 21 by a group of bikers, and of taking “full responsibility” for it.
GREENE: I’ll just read a little bit here: “The hairy horde looked at each other. It was their lucky day. ‘How bout yous come to our place for a party.’” And you ended up with them, and then you proceeded to describe what they were asking you to do. “‘Get your bleeping clothes off, shut the bleep up, hurry up, we got bleep to do, hit her in the back of the head so it don’t leave no marks.’” This certainly sounds like an awful, awful experience with these men.
HYNDE: Uh, yeah. I suppose, if that’s how you read it, then that, yeah. You know, I was having fun, because I was so stoned. I didn’t even care. That’s what I was talking about, I was talking about the drugs more than anything, and how f***** up we were. And how it impaired our judgment to the point where it just had gotten off the scale.
Here’s what happens if astronomers make contact with a civilization on another planet.
The false alarm happened in 1997.
The Green Bank Radio Observatory in Green Bank, West Virginia, was picking up some unusual signals—and Seth Shostak, then the head of the Center for Search for Extraterrestrial Intelligence (SETI) Research in Mountain View, Caifornia, was convinced that they had come from intelligent life somewhere in the universe.
“It looked like it might be the real deal,” Shostak recalled. Within a few hours, he had a call from The New York Times.
But within a day, it became clear that the source of excitement was actually a European satellite. To make matters worse, a second telescope in Georgia, which would have told the scientists about the true nature of the signal, wasn’t working.
Forget the Common Core, Finland’s youngsters are in charge of determining what happens in the classroom.
“The changes to kindergarten make me sick,” a veteran teacher in Arkansas recently admitted to me. “Think about what you did in first grade—that’s what my 5-year-old babies are expected to do.”
The difference between first grade and kindergarten may not seem like much, but what I remember about my first-grade experience in the mid-90s doesn’t match the kindergarten she described in her email: three and a half hours of daily literacy instruction, an hour and a half of daily math instruction, 20 minutes of daily “physical activity time” (officially banned from being called “recess”) and two 56-question standardized tests in literacy and math—on the fourth week of school.
That American friend—who teaches 20 students without an aide—has fought to integrate 30 minutes of “station time” into the literacy block, which includes “blocks, science, magnetic letters, play dough with letter stamps to practice words, books, and storytelling.” But the most controversial area of her classroom isn’t the blocks nor the stamps: Rather, it’s the “house station with dolls and toy food”—items her district tried to remove last year. The implication was clear: There’s no time for play in kindergarten anymore.
American politicians are now eager to disown a failed criminal-justice system that’s left the U.S. with the largest incarcerated population in the world. But they've failed to reckon with history. Fifty years after Daniel Patrick Moynihan’s report “The Negro Family” tragically helped create this system, it's time to reclaim his original intent.
By his own lights, Daniel Patrick Moynihan, ambassador, senator, sociologist, and itinerant American intellectual, was the product of a broken home and a pathological family. He was born in 1927 in Tulsa, Oklahoma, but raised mostly in New York City. When Moynihan was 10 years old, his father, John, left the family, plunging it into poverty. Moynihan’s mother, Margaret, remarried, had another child, divorced, moved to Indiana to stay with relatives, then returned to New York, where she worked as a nurse. Moynihan’s childhood—a tangle of poverty, remarriage, relocation, and single motherhood—contrasted starkly with the idyllic American family life he would later extol.

What went wrong with the conversion ministry, according to Alan Chambers, who once led its largest organization
In 2001, Alan Chambers was hired as the president of the world’s largest ex-gay ministry, Exodus International. That same year, U.S. Surgeon General David Satcher issued a report that stated, “there is no valid evidence showing that sexual orientation can be changed.”
Like most conservative Christian leaders at the time, Chambers considered the countercultural nature of his work a point of pride. During the latter part of the 20th century, Exodus and similar conservative groups promoted the idea that gay people could—and should try to—become straight. Ex-gay leaders traveled to churches and appeared on television news programs citing a litany of examples of happily married “former homosexuals” to demonstrate that sexual orientation is a choice and that change is possible.
Two hundred fifty years of slavery. Ninety years of Jim Crow. Sixty years of separate but equal. Thirty-five years of racist housing policy. Until we reckon with our compounding moral debts, America will never be whole.
And if thy brother, a Hebrew man, or a Hebrew woman, be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee. And when thou sendest him out free from thee, thou shalt not let him go away empty: thou shalt furnish him liberally out of thy flock, and out of thy floor, and out of thy winepress: of that wherewith the LORD thy God hath blessed thee thou shalt give unto him. And thou shalt remember that thou wast a bondman in the land of Egypt, and the LORD thy God redeemed thee: therefore I command thee this thing today.
— Deuteronomy 15: 12–15
Besides the crime which consists in violating the law, and varying from the right rule of reason, whereby a man so far becomes degenerate, and declares himself to quit the principles of human nature, and to be a noxious creature, there is commonly injury done to some person or other, and some other man receives damage by his transgression: in which case he who hath received any damage, has, besides the right of punishment common to him with other men, a particular right to seek reparation.
The Red Planet once had an ocean and a magnetic field. A new mission is setting out to discover what happened to them.
The question of whether there is life on Mars is woven into a much larger thatch of mysteries. Among them: What happened to the ancient ocean that once covered a quarter of the planet’s surface? And, relatedly, what made Mars’s magnetosphere fade away? Why did a planet that may have looked something like Earth turn into a dry red husk?
“We see magnetized rocks on the Mars surface,” said Bruce Banerdt, the principal investigator of the InSight mission to Mars, which is set to launch in March. “And so we know Mars had a magnetic field at one time, but it doesn't today. We would like to know the history—when that magnetic field started, when it may have shut down.”
There are a few leading theories about what decimated the planet’s magnetism. One of them is that huge asteroids bombarded Mars until its magnetic field turned off. That storm of asteroids may have included one enormous rock in particular, even bigger than the one believed to have wiped out Earth’s dinosaurs. Another theory explores the possibility that Mars’s ancient magnetic field only ever covered one of its hemispheres, an idea that would also explain how the planet’s magnetism weakened over time. “The presence of a magnetic field is key to understanding the history of Mars’s atmosphere, which of course is key to habitability on Mars’s surface,” Banerdt told me.
The country has seen periods of turmoil before. But this time may be different.
I am usually an optimist when it comes to Turkey’s future. Indeed, I wrote a whole book about The Rise of Turkey. But these days, I’m worried. The country faces a toxic combination of political polarization, government instability, economic slowdown, and threats of violence—from both inside and outside Turkey—that could soon add up to a catastrophe. The likelihood of that outcomeis increasing amid Russia’s bombing raids in Syria in support of its ally, Syrian President Bashar al-Assad, which threaten to debilitate the moderate rebels and boost the extremists in Syria’s civil war, while leaving Turkey to deal with two unruly neighbors: Assad and ISIS.
Of course, Turkey has gone through periods of political and economic crisis before. During the 1970s, the country’s economy collapsed, and the instability led to fighting among right- and left-wing militant groups and security forces that killed thousands of people. Then, in the 1990s, Turkey was pummeled by triple-digit inflation and a full-blown Kurdish insurgency that killed tens of thousands. Turkey survived both those decades. The historian in me says that Turkey will be able to withstand the coming shock this time as well.
In the name of emotional well-being, college students are increasingly demanding protection from words and ideas they don’t like. Here’s why that’s disastrous for education—and mental health.
Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law—or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia—and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.
