When Justina Walford moved to New York City nine years ago, she’d never felt more alone. She’d left behind her Church, her God, and her old city, Los Angeles. Then a secular congregation called Sunday Assembly filled the spiritual void—at least for a time.

Walford had just turned 40. As a child, she had been deeply religious. Her parents had no interest in religion, and didn’t understand why she would; they’d sent her to a Christian school in hopes of good discipline and education. But Justina fell headlong into faith, delighting in her Church community and dreaming of one day becoming a pastor herself.

By the time she turned up in New York, her faith had long since unraveled, a casualty of overseas travel that made her question how any one religious community could have a monopoly on truth. But still she grieved the loss of God. “It was like breaking up with someone that you thought was your soulmate,” Walford told me. “It’s for the better. It’s for your own good,” she remembered thinking. Even though it no longer made sense to her to believe, she felt a gaping hole where her Church—her people, her psalms, her stained-glass windows—used to be.

Raj Chetty got his biggest break before his life began. His mother, Anbu, grew up in Tamil Nadu, a tropical state at the southern tip of the Indian subcontinent. Anbu showed the greatest academic potential of her five siblings, but her future was constrained by custom. Although Anbu’s father encouraged her scholarly inclinations, there were no colleges in the area, and sending his daughter away for an education would have been unseemly.

But as Anbu approached the end of high school, a minor miracle redirected her life. A local tycoon, himself the father of a bright daughter, decided to open a women’s college, housed in his elegant residence. Anbu was admitted to the inaugural class of 30 young women, learning English in the spacious courtyard under a thatched roof and traveling in the early mornings by bus to a nearby college to run chemistry experiments or dissect frogs’ hearts before the men arrived.

My maternal grandparents met through mutual friends at a summer pool party in the suburbs of Detroit shortly after World War II. Thirty years later, their oldest daughter met my dad in Washington, D.C., at the suggestion of a mutual friend from Texas. Forty years after that, when I met my girlfriend in the summer of 2015, one sophisticated algorithm and two rightward swipes did all the work.

My family story also serves as a brief history of romance. Robots are not yet replacing our jobs. But they’re supplanting the role of matchmaker once held by friends and family.

For the last ten years, Stanford sociologist Michael Rosenfeld has been compiling data on how couples meet one another. In almost any other period, this project would have been an excruciating bore. That’s because for centuries, most couples met the same way: They relied on their families and friends to set them up. In sociology-speak, our relationships were “mediated.” In human-speak, your wingman was your dad.

Elizabeth Warren was walking around Milwaukee a week and a half ago, listening to a community activist and a 22-year-old whose parents are undocumented immigrants. They told her the history of bilingual education in the neighborhood around Walker Square Park, and how the blocks have changed over the years. “Talk to me about housing,” Warren said. “Where are the teachers drawn from?” The group walked past a sign for the oldest Latino-advocacy agency in the city, and a gentrification signpost: a store called Antiques Addict.

Warren was in Wisconsin to speak at a Latino political conference. She used the day to release her immigration plan, the latest in a stream of plans proposing how to revamp the system, in ways that go far beyond what Washington wisdom deems possible. The neighborhood walk felt as if Warren’s campaign was merely banking B-roll footage for future ads, while a bunch of reporters tripped over curbs and fire hydrants watching the candidate interact with locals. We ended in a parking lot, beneath a mural of a bald eagle facing a dove under a rainbow, with an olive branch in their beaks, a lightning bolt striking the section closest to the dove.  

About 4.5 billion years ago, according to the most popular theory of the moon’s formation, a mysterious rocky world the size of Mars slammed into Earth. From the fiery impact, shards swirled and fused into a new, airless world, itself bombarded with rocky objects. In the absence of the smoothing touch of weather and tectonic activity, every dent remained. And then, one day, among craters both microscopic and miles-wide, two guys came along and stepped on the surface, carving new hollows with their boots.

Buzz Aldrin, seeing the moon from the surface for the first time, described it as “magnificent desolation.”

It was not so desolate when they departed. The Apollo 11 astronauts discarded gadgets, tools, and the clothesline contraption that moved boxes of lunar samples, one by one, from the surface into the module. They left behind commemorative objects—that resplendent American flag, mission patches and medals honoring fallen astronauts and cosmonauts, a coin-size silicon disk bearing goodwill messages from the world leaders of planet Earth. And they dumped things that weren’t really advertised to the public, for understandable reasons, such as defecation-collection devices. (Some scientists, curious to examine how gut microbes fare in low gravity, even proposed going back for these.)

These days, not even the rich feel rich. According to a recent survey by the financial advisory firm Ameriprise Financial, only 13 percent of American millionaires classify themselves as wealthy. Even some of those surveyed who had more than $5 million across their bank accounts, investments, and retirement accounts said they didn’t feel rich. If multimillionaires don’t feel wealthy, who does?

I decided to go to Elizabeth Dunn, a professor of psychology at the University of British Columbia and a co-author of Happy Money: The Science of Happier Spending, with my question: Once people have enough money to cover their basic needs and then some, what would make them feel satisfied—happy, even—with what they have? Dunn said she didn’t know of any academic studies that addressed this question head-on, but she did point to some related research that provides possible answers.

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.

In May 2014, a 56-year-old man arrived in the emergency department at the veterans' hospital in Little Rock, Arkansas. He reported intense but vague symptoms: weakness, fatigue, and body aches. The emergency-room team drew some of his blood and found it bursting with a waste chemical called creatinine—more than four times the normal level. That meant he was experiencing severe kidney failure. Doctors started urgent dialysis, cycling the blood out of the man's body, through a machine that cleaned it in lieu of functional kidneys.

The University of Arkansas physicians who managed the case were perplexed, they report in the current issue of The New England Journal of Medicine. What causes an otherwise healthy person to develop such dramatic renal failure? Another clue initially confused the picture: Urine tests found oxalate crystals at more than twice the upper limit of normal. When they show up in those quantities, doctors are taught to ask if the person has been drinking antifreeze, because ethylene glycol can cause oxalate crystals to accumulate. This man denied drinking antifreeze—as people who drink antifreeze tend to do. But the doctors didn't need to pursue that line because, they report, "on further questioning, the patient admitted to drinking 16 eight-ounce glasses of iced tea daily." And then it made sense.

A few years ago, I lived in a walkup apartment in the East Village of New York. Every so often descending the stairway, I would catch a glimpse of a particular family with young children in its Sisyphean attempts to reach the fourth floor. The mom would fold the stroller to the size of a boogie board, then drag it behind her with her right hand, while cradling the younger and typically crying child in the crook of her left arm. Meanwhile, she would shout hygiene instructions in the direction of the older child, who would slap both hands against every other grimy step to use her little arms as leverage, like an adult negotiating the boulder steps of Machu Picchu. It looked like hell—or, as I once suggested to a roommate, a carefully staged public service announcement against family formation.

For seven and a half minutes on the night of July 20, 1969, Pink Floyd took thousands of BBC viewers to the moon. Of course, two men were already there: Neil Armstrong and Buzz Aldrin, the Apollo 11 astronauts who became the first human beings to set foot on the lunar surface. However, the members of Pink Floyd—David Gilmour, Roger Waters, Nick Mason, and Richard Wright—weren’t using science, calculus, and technology to transport people through space on that fateful evening. They were using music, specifically an improvised and largely forgotten song called “Moonhead.”

The piece isn’t ranked with Pink Floyd classics such as “Wish You Were Here” or “Another Brick in the Wall, Part 2.” Over the decades, “Moonhead” has remained one of the most overlooked entries in the band’s canon, despite its historic status. Pink Floyd was commissioned by the BBC to perform instrumental music live on the air as the Apollo 11 crew’s video and audio signals came streaming in across the emptiness of space, beating the Soviets at the race that had been spurred on by John F. Kennedy’s rousing moonshot speech in 1962.
