The American conventional wisdom about weight loss is simple: A calorie deficit is all that’s required to drop excess pounds, and moderating future calorie consumption is all that’s required to maintain it. To the idea’s adherents, the infinite complexity of human biology acts as one big nutritional piggy bank. Anyone who gains too much weight or loses weight and gains it back has simply failed to balance the caloric checkbook, which can be corrected by forswearing fatty food or carbs.

Endocrinologists have known for decades that the science of weight is far more complicated than calorie deficits and energy expenditures. And in 2016, the fickle complexity of weight came to broad national attention. In a study of former contestants on a season of the weight-loss reality show The Biggest Loser, scientists found that years later, the contestants not only had gained back much or all of the weight they’d lost on the show, but also had far weaker metabolisms than most people their size. The contestants’ bodies had fought for years to regain the weight, contrary to the contestants’ efforts and wishes. No one was sure why.

Robert Spada walked into the decrepit warehouse in Detroit and surveyed the chaos: Thousands of cardboard boxes and large plastic bags were piled haphazardly throughout the cavernous space. The air inside was hot and musty. Spada, an assistant prosecutor, saw that some of the windows were open, others broken, exposing the room to the summer heat. Above the boxes, birds glided in slow, swooping circles.

It was August 17, 2009, and this brick fortress of a building housed evidence that had been collected by the Detroit Police Department. Spada’s visit had been prompted by a question: Why were police sometimes unable to locate crucial evidence? The answer lay in the disarray before him.

Editor's Note: This article is part of a series reflecting on the Apollo 11 mission, 50 years later.

Without the computers on board the Apollo spacecraft, there would have been no moon landing, no triumphant first step, no high-water mark for human space travel. A pilot could never have navigated the way to the moon, as if a spaceship were simply a more powerful airplane. The calculations required to make in-flight adjustments and the complexity of the thrust controls outstripped human capacities.

The Apollo Guidance Computer, in both its guises—one on board the core spacecraft, and the other on the lunar module—was a triumph of engineering. Computers had been the size of rooms and filled with vacuum tubes, and if the Apollo computer, at 70 pounds, was not exactly miniature yet, it began “the transition between people bragging about how big their computers are … and bragging about how small their computers are,” the MIT aerospace and computing historian David Mindell once joked in a lecture.

I live in envy. I envy the people who know their nationality. All the people whose nationality has never been a question in their mind.

I can imagine the woman staring at her reflection in the Volta River who knows she’s Ghanaian, like her ancestors who liberated their people in 1957 and chose the mighty pre-colonial Ghana as the name of their new nation. I can imagine the woman flying into Frankfurt who knows she’s German, who knows she’s arriving back home. I can imagine the man working on his antique car outside his home in Biloxi, forehead covered by the prized blood-red baseball cap he purchased at a rally back in November, a man who has never been told, “Go back to your country!” If somehow someone did tell him, it would confuse him as much as it would the Ghanaian or German woman. It would be like someone driving by his house and shouting at him, “Go back to your home!”

The first quotation from Donald Trump ever to appear in The New York Times came on October 16, 1973. Trump was responding to charges filed by the Justice Department alleging racial bias at his family’s real-estate company. “They are absolutely ridiculous,” Trump said of the charges. “We have never discriminated, and we never would.”

In the years since then, Trump has assembled a long record of comment on issues involving African Americans as well as Mexicans, Hispanics more broadly, Native Americans, Muslims, Jews, immigrants, women, and people with disabilities.

President Donald Trump obviously has no boundaries, let alone any understanding of historical tropes, but he really should not have roped the Jewish state into his latest Twitter tirade against four Democratic congresswomen (or, as he put it in his Joe McCarthy–inflected English, “Democrat Congresswomen”). “When will the Radical Left Congresswomen apologize to our Country, the people of Israel and even to the Office of the President, for the foul language they have used, and the terrible things they have said,” wrote the leader of the free world. “I can tell you that they have made Israel feel abandoned by the U.S.”

Trump’s ire was directed at the “squad,” the quartet of outspoken female Democratic legislators whose ranks include Ilhan Omar of Minnesota, Alexandria Ocasio-Cortez of New York, Ayanna Pressley of Massachusetts, and Rashida Tlaib of Michigan. For the past two weeks, the women have been embroiled in a very public spat with House Speaker Nancy Pelosi, whom they consider insufficiently left-wing and overly solicitous toward the president. Trump, unable to let an intra–Democratic Party tussle play out to his own electoral advantage, chose to intervene, with what can only be described as a racist attack on four ethnic-minority women. The lawmakers, “who originally came from countries whose governments are a complete and total catastrophe,” he wrote, ought to “go back and help fix the totally broken and crime infested places from which they came.”

At first glance, the classroom I was visiting at a high-poverty school in Washington, D.C., seemed like a model of industriousness. The teacher sat at a desk in the corner, going over student work, while the first graders quietly filled out a worksheet intended to develop their reading skills.

As I looked around, I noticed a small girl drawing on a piece of paper. Ten minutes later, she had sketched a string of human figures, and was busy coloring them yellow.

I knelt next to her and asked, “What are you drawing?”

“Clowns,” she answered confidently.

“Why are you drawing clowns?”

“Because it says right here, ‘Draw clowns,’ ” she explained.

Running down the left side of the worksheet was a list of reading-comprehension skills: finding the main idea, making inferences, making predictions. The girl was pointing to the phrase draw conclusions. She was supposed to be making inferences and drawing conclusions about a dense article describing Brazil, which was lying facedown on her desk. But she was unaware that the text was there until I turned it over. More to the point, she had never heard of Brazil and was unable to read the word.

When President Donald Trump declared himself a “nationalist,” he was telling the truth, but he was inadequately specific.

On Sunday morning, the president told four members of Congress to “go back” to the countries “from which they came.” The remark, a racist taunt with a historic pedigree, inspired a flurry of fact-checking from mainstream journalists who were quick to note that Rashida Tlaib, Alexandria Ocasio-Cortez, Ayanna Pressley, and Ilhan Omar are American citizens, and that only Omar was born abroad, in Somalia. It was a rather remarkable exercise in missing the point.

When Trump told these women to “go back,” he was not making a factual claim about where they were born. He was stating his ideological belief that American citizenship is fundamentally racial, that only white people can truly be citizens, and that people of color, immigrants in particular, are only conditionally American. This is a cornerstone of white nationalism, and one of the president’s few closely held ideological beliefs. It is a moral conviction, not a statement of fact. If these women could all trace their family line back to 1776, it would not make them more American than Trump, a descendant of German immigrants whose ancestors arrived relatively recently, because he is white and they are not.

In some ways, President Donald Trump refuses to follow any of the established rules, like avoiding open racism. In others, he is perfectly derivative—for example, when called on his racist remarks, the president reverted to one of the most tired cliches in the book:

Those Tweets were NOT Racist. I don’t have a Racist bone in my body! The so-called vote to be taken is a Democrat con game. Republicans should not show “weakness” and fall into their trap. This should be a vote on the filthy language, statements and lies told by the Democrat.....

As Christopher Petrella and Justin Gomer wrote in an April Washington Post essay on the history of “racist bones,” the phrase gained currency during the Reagan administration. When confronted about the racial impacts of its policies, the White House would simply insist it didn’t see color; the policies were intended to affect everyone the same. It took to citing Martin Luther King Jr.’s exhortation to judge people on their character rather than skin color: “This embrace of colorblindness—a selective and distorted reading of what King actually advocated—enabled Reagan to frame his relentless attacks on civil rights as motivated by a morally righteous and apolitical commitment to equality.”

Last April, I received an odd email from a man named Matthew Cox. “I am an inmate at the Coleman Federal Correctional Complex in Florida,” he wrote. “I’m also a true crime writer.” He had one year left on his sentence and was “attempting to develop a body of work that will allow me to exit prison with a new career.” He included a story about a fellow inmate who’d been ensnared in a complicated currency-trading scam, hoping that I’d write about it for The Atlantic.

“This is fascinating,” I replied. I didn’t mean the currency-trading scam, which was too procedural for my tastes, but Cox’s own trajectory. He described himself as “an infamous con man writing his fellow inmates’ true crime stories while immersed in federal prison.” I’d never had a possible subject pitch his own tale so aptly. I wasn’t entirely sure that was a good thing.
