As Mr. Trump surely knows, the new Saudi cover story is contradicted not just by evidence collected by Turkish authorities and by journalists but also by the reporting of the U.S. intelligence community. All point to Mohammed bin Salman as the instigator of a premeditated, cold-blooded and brutal murder, followed by the dismemberment of Mr. Khashoggi’s body. As The Post’s Shane Harris reported, CIA officials have listened to an audio recording in the possession of Turkish officials they say backs up their account that Mr. Khashoggi was murdered minutes after entering the consulate by a team of 15 men. The Post has identified five of those men as probable members of the crown prince’s personal security detail.

American maverick who insisted that the only way to tell a great story was to go out and report it.

journalism could offer the kinds of literary pleasure found in books.

Wolfe scorned the reluctance of American writers to confront social issues and warned that self-absorption and master’s programs would kill the novel. “So the doors close and the walls go up!” he wrote in his 1989 literary manifesto, “Stalking the Billion-Footed Beast.” He was astonished that no author of his generation had written a sweeping, 19th century style novel about contemporary New York City, and ended up writing one himself, “The Bonfire of the Vanities.”

We should be very careful in thinking about whether we’re working on the right problems. If we don’t, that ties into the problem that we don’t have experimental evidence that could move us forward. We're trying to develop theories that we use to find out which are good experiments to make, and these are the experiments that we build.   We build particle detectors and try to find dark matter; we build larger colliders in the hope of producing new particles; we shoot satellites into orbit and try to look back into the early universe, and we do that because we hope there’s something new to find there. We think there is because we have some idea from the theories that we’ve been working on that this would be something good to probe. If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.

I’m still asking myself the same question that I asked myself ten years ago: "What is going on in my community?" I work in the foundations of physics, and I see a lot of strange things happening there. When I look at the papers that are being published, many of them seem to be produced simply because papers have to be produced. They don’t move us forward in any significant way. I get the impression that people are working on them not so much because it’s what they’re interested in but because they have to produce outcomes in a short amount of time. They sit on short-term positions and have short-term contracts, and papers must be produced.

The field that I mostly work in is the foundations of physics, which is, roughly speaking, composed of cosmology, the foundations of quantum mechanics, high-energy particle physics, and quantum gravity. It’s a peculiar field because there hasn’t been new data for almost four decades, since we established the Standard Model of particle physics. There has been, of course, the Higgs particle that was discovered at the LHC in 2012, and there have been some additions to the Standard Model, but there has not been a great new paradigm change, as Kuhn would have put it. We’re still using the same techniques, and we’re still working with the same theories as we did in the 1970s.

What I was doing was perfectly legal. In North Carolina, long-gun transfers by private sellers require no background checks.

Among young adults who regularly use smartphones and tablets, just reading a story or performing a task on a screen instead of on paper led to greater focus on concrete details, but less ability to infer meaning or quickly get the gist of a problem,

The findings align with other emerging research on how students process information differently in print and digital forms. A 2014 series of experiments found that while taking more notes overall was better than taking fewer, students who typed notes on their laptops rather than writing them on paper tended to take down information verbatim rather than summarizing concepts, and the more students wrote verbatim, the less they remembered a week later. 

For example, she said, teachers should consider the format of information when designing different types of activities, to help students focus on details or overall themes. 

The matter is by no means settled. Before 1992 most studies concluded that people read slower, less accurately and less comprehensively on screens than on paper. Studies published since the early 1990s, however, have produced more inconsistent results: a slight majority has confirmed earlier conclusions, but almost as many have found few significant differences in reading speed or comprehension between paper and screens. And recent surveys suggest that although most people still prefer paper—especially when reading intensively—attitudes are changing as tablets and e-reading technology improve and reading digital books for facts and fun becomes more common.

Compared with paper, screens may also drain more of our mental resources while we are reading and make it a little harder to remember what we read when we are done. A parallel line of research focuses on people's attitudes toward different kinds of media. Whether they realize it or not, many people approach computers and tablets with a state of mind less conducive to learning than the one they bring to paper.

Both anecdotally and in published studies, people report that when trying to locate a particular piece of written information they often remember where in the text it appeared. We might recall that we passed the red farmhouse near the start of the trail before we started climbing uphill through the forest; in a similar way, we remember that we read about Mr. Darcy rebuffing Elizabeth Bennett on the bottom of the left-hand page in one of the earlier chapters.

We must think more critically about how we communicate via social media.
