In firing Steve Bannon, President Trump has lost his chief ideologue, the man who channeled his base and advocated for the populist-nationalist policies that helped propel Trump to victory.

But he has gained an unpredictable and potentially troublesome outside ally who has long experience running a media organization, and an even longer list of enemies with whom he has scores to settle both outside the administration and inside. “Steve is now unchained,” said a source close to Bannon. “Fully unchained.”

“He’s going nuclear,” said another friend. “You have no idea. This is gonna be really fucking bad.”

Bannon had in recent days mused about leaving, according to people who have spoken with him; he has expressed to friends that he feels the administration is failing and is a sinking ship. And last week, he told people in a meeting that he would have 10 times more influence outside the White House than inside it.

In a 2012 article published in the Public Opinion Quarterly, a group of researchers shared the results of a study they had done in the aftermath of the 2008 U.S. presidential election. The researchers, based on panels with young voters, found that the impression of Sarah Palin that Tina Fey had made famous on Saturday Night Live—“I can see Russia from my house!”—had changed the public’s feeling about the actual vice-presidential candidate. Fey’s jokes, the researchers suggested, had proven comedy’s power, especially in times of question and perhaps also in times of crisis, to shape people’s sense of the world. The jokes had woven themselves into the workings of American democracy. The researchers called it the Fey Effect.

Steve Bannon, the enigmatic but influential strategist who joined Donald Trump’s campaign at a low ebb, helped coax a win in the 2016 election from it, and then won acclaim and hatred as Trump’s eminence grise, is leaving the White House.

It is the latest in a string of senior departures from a White House that—like the Republican Party itself—was split between establishment Republicans and populist outsiders. But Bannon’s exit, following on the heels of those other departures, leaves Trump largely untethered from the Republican Party—and the president’s ideology, never especially defined on most issues, even more up for grabs.

In a statement Friday afternoon, White House Press Secretary Sarah Huckabee Sanders said, “White House Chief of Staff John Kelly and Steve Bannon have mutually agreed today would be Steve's last day. We are grateful for his service and wish him the best.” The New York Times had reported that Trump had told aides he was going to remove Bannon. Rumors of Bannon’s demise have bubbled up repeatedly over Trump’s seven months in office, but each time they proved to be wrong—or at least premature.

The scientists are all talking like it’s a sure thing.

On August 21, the “moon” will pass between the Earth and the sun, obscuring the light of the latter. The government agency NASA says this will result in “one of nature’s most awe-inspiring sights.” The astronomers there claim to have calculated down to the minute exactly when and where this will happen, and for how long. They have reportedly known about this eclipse for years, just by virtue of some sort of complex math.

This seems extremely unlikely. I can’t even find these eclipse calculations on their website to check them for myself.

Meanwhile the scientists tell us we can’t look at it without special glasses because “looking directly at the sun is unsafe.”

One day last summer, around noon, I called Athena, a 13-year-old who lives in Houston, Texas. She answered her phone—she’s had an iPhone since she was 11—sounding as if she’d just woken up. We chatted about her favorite songs and TV shows, and I asked her what she likes to do with her friends. “We go to the mall,” she said. “Do your parents drop you off?,” I asked, recalling my own middle-school days, in the 1980s, when I’d enjoy a few parent-free hours shopping with my friends. “No—I go with my family,” she replied. “We’ll go with my mom and brothers and walk a little behind them. I just have to tell my mom where we’re going. I have to check in every hour or every 30 minutes.”

Those mall trips are infrequent—about once a month. More often, Athena and her friends spend time together on their phones, unchaperoned. Unlike the teens of my generation, who might have spent an evening tying up the family landline with gossip, they talk on Snapchat, the smartphone app that allows users to send pictures and videos that quickly disappear. They make sure to keep up their Snapstreaks, which show how many days in a row they have Snapchatted with each other. Sometimes they save screenshots of particularly ridiculous pictures of friends. “It’s good blackmail,” Athena said. (Because she’s a minor, I’m not using her real name.) She told me she’d spent most of the summer hanging out alone in her room with her phone. That’s just the way her generation is, she said. “We didn’t have a choice to know any life without iPads or iPhones. I think we like our phones more than we like actual people.”

A compelling case can be made for the advantages, particularly for college-educated women, of delaying marriage until after the mid-twenties, as Eleanor Barkhorn recently wrote here. As a math-phobic English professor, I'm not one to wrestle with statistics, but I believe a robust case can be made, alternatively, for young marriage.

There are costs to delaying marriage, a phenomenon that has reached a new threshold, with the average age of marriage for men reaching the historic high of 29 and women 27. New research from Knot Yet, a project that explores the benefits and costs of delayed marriage in America, points to some of the risks of waiting so long to marry. While delayed marriage does have economic benefits for college educated women and is credited with bringing down the overall divorce rate, the news isn't all good:

The strangest part about the continued personality cult of Robert E. Lee is how few of the qualities his admirers profess to see in him he actually possessed.

Memorial Day has the tendency to conjure up old arguments about the Civil War. That’s understandable; it was created to mourn the dead of a war in which the Union was nearly destroyed, when half the country rose up in rebellion in defense of slavery. This year, the removal of Lee’s statue in New Orleans has inspired a new round of commentary about Lee, not to mention protests on his behalf by white supremacists.

The myth of Lee goes something like this: He was a brilliant strategist and devoted Christian man who abhorred slavery and labored tirelessly after the war to bring the country back together.

Another day, another sputtering orgy of confusion following a cryptic Donald Trump tweet. This one came Thursday, a few hours after a van plowed into a crowd on the Barcelona pedestrian mall of Las Ramblas, an attack claimed by the reeling Islamic State. The president replied, via iPhone:

Study what General Pershing of the United States did to terrorists when caught. There was no more Radical Islamic Terror for 35 years!

— Donald J. Trump (@realDonaldTrump) August 17, 2017

It seemed to be a reference to a story Trump told at campaign rallies during the 2016 primaries, which in turn was a garbled version of an Islamophobic meme that has made its way around the internet for years. In the fable, the legendary U.S. General John J. Pershing once ended a wave of Muslim terrorism in the Philippines by executing prisoners with bullets dipped in pigs’ blood. Other superstitious fighters were so terrified by the prospect of being killed while touching part of a forbidden animal, the story goes, that fighting immediately stopped, for some period of time. (For 25 years, Trump said at a North Charleston, South Carolina, rally in February 2016; a few weeks later, in Costa Mesa, California, it had jumped up to 42.)

When did America become untethered from reality?

I first noticed our national lurch toward fantasy in 2004, after President George W. Bush’s political mastermind, Karl Rove, came up with the remarkable phrase reality-based community. People in “the reality-based community,” he told a reporter, “believe that solutions emerge from your judicious study of discernible reality … That’s not the way the world really works anymore.” A year later, The Colbert Report went on the air. In the first few minutes of the first episode, Stephen Colbert, playing his right-wing-populist commentator character, performed a feature called “The Word.” His first selection: truthiness. “Now, I’m sure some of the ‘word police,’ the ‘wordinistas’ over at Webster’s, are gonna say, ‘Hey, that’s not a word!’ Well, anybody who knows me knows that I’m no fan of dictionaries or reference books.

First, listen to the story with the happy ending: At 61, the executive was in excellent health. His blood pressure was a bit high, but everything else looked good, and he exercised regularly. Then he had a scare. He went for a brisk post-lunch walk on a cool winter day, and his chest began to hurt. Back inside his office, he sat down, and the pain disappeared as quickly as it had come.

That night, he thought more about it: middle-aged man, high blood pressure, stressful job, chest discomfort. The next day, he went to a local emergency department. Doctors determined that the man had not suffered a heart attack and that the electrical activity of his heart was completely normal. All signs suggested that the executive had stable angina—chest pain that occurs when the heart muscle is getting less blood-borne oxygen than it needs, often because an artery is partially blocked.
