In the early 2000s Terry Mitchell’s dentist retired. For a while, Mitchell, an electrician in his 50s, stopped seeking dental care altogether. But when one of his wisdom teeth began to ache, he started looking for someone new. An acquaintance recommended John Roger Lund, whose practice was a convenient 10-minute walk from Mitchell’s home, in San Jose, California. Lund’s practice was situated in a one-story building with clay roof tiles that housed several dental offices. The interior was a little dated, but not dingy. The waiting room was small and the decor minimal: some plants and photos, no fish. Lund was a good-looking middle-aged guy with arched eyebrows, round glasses, and graying hair that framed a youthful face. He was charming, chatty, and upbeat. At the time, Mitchell and Lund both owned Chevrolet Chevelles, and they bonded over their mutual love of classic cars.

Ken Jennings rose to fame after an unprecedented run on Jeopardy 15 years ago: Over the course of 74 episodes, he won a total of roughly $2.5 million.

Recently, a contestant named James Holzhauer has been working toward Jennings’s record at an astonishing pace. After the Friday-evening broadcast of the quiz program, Holzhauer had won about $850,000 over just 12 episodes. If he keeps up that rate, he’ll reach $2.5 million in less than half the time it took Jennings to do so.

Before Holzhauer went on the show, the most money earned in a single episode of Jeopardy was $77,000. During his 12-episode streak, he’s beaten that total not once, but five times, and has set a new record of $131,127. Holzhauer’s success has been attributed not just to his deep trivia knowledge, but also to his aggressive style of play—he homes in on high-value tiles that might contain Daily Doubles, and then often bets enormous sums when he finds them—and his unmatched buzzer-pressing reflexes.

There has never been a town like the one San Francisco is becoming, a place where a single industry composed almost entirely of rich people thoroughly dominates the local economy. Much of the money that’s been squished out of the rest of the world gets funneled by the internet pipes to this little sliver of land on the Pacific Ocean, jutting out into the glory of the bay. The city now sits atop a geyser of cash created from what the scholar Shoshana Zuboff calls “behavioral surplus”—the natural resource created from your behavior, which is to say your mind.

Literal colonies of the working poor now cling to forgotten streets in RV communities. Homeless encampments are stitched onto any liminal plot of land. To lose your apartment doesn’t mean moving one neighborhood over but three cities away, to Antioch or Gilroy or Stockton.

The proliferation of retail boutiques in California did not really bother him, Evan told me, but the billboards did. Advertisements for delivery, advertisements promoting the substance for relaxation, for fun, for health. “Shop. It’s legal.” “Hello marijuana, goodbye hangover.” “It’s not a trigger,” he told me. “But it is in your face.”

When we spoke, he had been sober for a hard-fought seven weeks: seven weeks of sleepless nights, intermittent nausea, irritability, trouble focusing, and psychological turmoil. There were upsides, he said, in terms of reduced mental fog, a fatter wallet, and a growing sense of confidence that he could quit. “I don’t think it’s a ‘can’ as much as a ‘must,’” he said.

The great white shark—a fast, powerful, 16-foot-long torpedo that’s armed to the teeth with teeth—has little to fear except fear itself. But also: killer whales.

For almost 15 years, Salvador Jorgensen from the Monterey Bay Aquarium has been studying great white sharks off the coast of California. He and his colleagues would lure the predators to their boats using bits of old carpet that they had cut in the shape of a seal. When the sharks approached, the team would shoot them with electronic tags that periodically emit ultrasonic signals. Underwater receivers, moored throughout Californian waters, detected these signals as the sharks swam by, allowing the team to track their whereabouts over time.

What’s called the American century was really just a little more than half a century, and that was the span of Richard Holbrooke’s life. It began with the Second World War and the creative burst that followed—the United Nations, the Atlantic alliance, containment, the free world—and it went through dizzying lows and highs, until it expired the day before yesterday. The thing that brings on doom to great powers—is it simple hubris, or decadence and squander, a kind of inattention, loss of faith, or just the passage of years? At some point that thing set in, and so we are talking about an age gone by. It wasn’t a golden age—there was plenty of folly and wrong—but I already miss it. The best about us was inseparable from the worst. Our feeling that we could do anything gave us the Marshall Plan and Vietnam, the peace at Dayton and the endless Afghan War. Our confidence and energy, our reach and grasp, our excess and blindness—they were not so different from Holbrooke’s. He was our man. That’s the reason to tell you this story.

Gérard Araud, the charmingly blunt French ambassador to the United States, is famous for two things: the lavish parties he hosts at his Kalorama mansion, and his willingness to say (and tweet) things that other ambassadors might not even think, much less state in public.

Araud ends his nearly five-year tenure in Washington today, and when I spoke with him last week, he was, even by his usual standards, direct to the point of discomfort. He told me his view of the U.S. (“The role of the United States as a policeman of the world, it’s over”) and Donald Trump (“brutal, a bit primitive, but in a sense he’s right” on free trade), and he shared his opinions of John Bolton (he’s a “real professional,” even though “he hates international organizations”) and Jared Kushner (“extremely smart, but he has no guts”).

It only took five minutes for Gavin Schmidt to out-speculate me.

Schmidt is the director of NASA’s Goddard Institute for Space Studies (a.k.a. GISS) a world-class climate-science facility. One day last year, I came to GISS with a far-out proposal. In my work as an astrophysicist, I’d begun researching global warming from an “astrobiological perspective.” That meant asking whether any industrial civilization that rises on any planet will, through their own activity, trigger their own version of a climate shift. I was visiting GISS that day hoping to gain some climate science insights and, perhaps, collaborators. That’s how I ended up in Gavin’s office.

Just as I was revving up my pitch, Gavin stopped me in my tracks.

Let’s get some things straight.

Passover is a springtime Jewish festival celebrating the early Israelites’ exodus from Egypt and freedom from slavery. Jews observe it by hosting a ritual dinner, called a seder, and then by abstaining from eating all leavened bread for about a week. (Some of us abstain from some other stuff, too.) Instead, we eat matzo, a thin, unleavened cracker.

Easter is a springtime Christian holiday celebrating the resurrection of Jesus Christ and freedom from sin and death. It is preceded by a series of holidays commemorating Jesus’s path to the cross. One of these holidays is Maundy Thursday, which, aside from being a great name for a holiday, is a remembrance of the Last Supper, which was a seder. In the United States, many Christians observe Easter by attending a ritual meal between breakfast and lunch, called a brunch.

Here is the hypothesis: Not so long ago, the very nature of planet Earth suffered a devastating rupture. The break was sudden, global, and irreversible. It happened on a Sunday within living memory. Mick Jagger, Meryl Streep, and Caitlyn Jenner were all born before this crack in time. Vladimir Putin, Liam Neeson, and Mr. T were all born after it.

That idea might soon carry the weight of scientific fact. Later this month, a committee of researchers from around the world will decide whether the Earth sprang into the Anthropocene, a new chapter of its history, in the year 1950. If accepted, this delineation will signal a new reality, that human activities, not natural processes, are now the dominant driver of change on Earth’s surface—that carbon pollution, climate change, deforestation, factory farms, mass die-offs, and enormous road networks have made a greater imprint on the planet than any other force in the past 12,000 years.
