For a little NASA spacecraft, the weather outside is frightful.

The Parker Solar Probe is on a mission toward the sun. The spacecraft has been exposed to scorching temperatures and intense sunlight as it draws closer with every loop around. Eventually, Parker will glide through the star’s outer atmosphere and feel the toastiness of nearly 2 million degrees Fahrenheit (more than 1 million degrees Celsius).

Parker is dressed appropriately for the journey. It wears a thick, custom-made shield to protect its scientific instruments and systems, and tubes with flowing water to cool itself down. Inside, it is a cozy 78 degrees Fahrenheit (26 degrees Celsius). Since it set out last summer, Parker has made three sweltering passes of the sun, with many more still to come in the next five years. And its findings are already surprising scientists back home.

Shortly after I met my wife, Cindy, in 1989—she was living in New York City at the time, while I was living in Northern Virginia—she told me about a new church she was attending in Manhattan: Redeemer Presbyterian. The young minister, she told me, was “the best pastor in America.”

His name was Timothy J. Keller.

Since that time Keller, 69, has become one of the most consequential figures in American Christianity. When he founded Redeemer in the fall of 1989, fewer than 100 people attended; in the aftermath of the attacks on September 11, 2001, Keller was preaching in multiple services in three different venues each Sunday to about 5,000 people—mostly young, single, professionally and ethnically diverse. He has written about two dozen books, several of them best sellers. And unlike that of many popular ministers, his reach extends far beyond the Christian subculture.

The internet has some feedback on Peloton’s holiday ad campaign. The fitness-tech company, famous for its $2,400, Wi-Fi-enabled stationary bikes that let riders stream spin classes, debuted a new television commercial in mid-November, but it didn’t become infamous until earlier this week, when Twitter got ahold of it.

In the ad, a young mom gains confidence in the year after her husband buys her a Peloton for Christmas—or, at least, that’s what the ad seems to be aiming for. The commercial documents the woman (who is also documenting herself, via her phone’s front-facing camera) while she gets up early day after day to exercise or jumps on the bike after work. At the end, she presents the video of her exercise journey to her husband. “A year ago, I didn’t realize how much this would change me,” she tells him. “Thank you.”

Perhaps fittingly for the end of the decade, 2019 was filled with thoughtful, retrospective works from master filmmakers who cast an eye on the past amid the rapid changes of the present. While veterans like Martin Scorsese and Quentin Tarantino wrestled with their moviemaking legacies, some of the other best works of the year were about the wrenching and rewarding labor that goes into a work of art, be it an 18th-century French portrait, an experimental student film in 1980s Britain, or one of the best-known works of American literature. By any measure, this was a thrilling year for the medium, featuring fascinating movies of all genres and styles to dissect, enjoy, and debate for decades to come. Here are my 10 favorites.

My mornings are the messiest part of my day. I do not rise and shine. Instead, I hit snooze on the alarm and throw the covers over my head. As I hear the early bus shuffle through my stop outside my window, my mind fills with thoughts from the night before, with to-do lists and deadlines. The alarm goes off again, and I repeat the snooze cycle twice more. By the time I roll out of bed, I’m a tangle of anxiety.

This never seems to be the case in other people’s morning routines. I know, because those routines now seem to be everywhere: in series like The Cut’s “How I Get It Done” and The New York Times’ “Sunday Morning,” in roundups on news outlets from CNN to Vogue, and in hashtagged Instagram pictures of frothy lattes cut with leafy designs. The subjects of most of these morning-routine reports are celebrities and other conventionally successful people. Richard Branson plays a “hard game” of tennis at 6 a.m. Elizabeth Gilbert makes homemade chai and dances.

Two of the nation’s last three presidents won the presidency in the Electoral College, even though they lost the popular vote nationwide. In 2000, Al Gore outpolled George W. Bush by more than 540,000 votes but lost in the Electoral College, 271–266. Sixteen years later, Hillary Clinton tallied almost 3 million more votes than Donald Trump but lost decisively in the Electoral College, 306–232. And, as a recent New York Times poll suggested, the 2020 election could very well again deliver the presidency to the loser of the popular vote.

Despite this, defenders of the Electoral College argue that it was created to combat majority tyranny and support federalism, and that it continues to serve those purposes. For example, Representative Dan Crenshaw of Texas, responding to Representative Alexandria Ocasio-Cortez’s recent criticism of the Electoral College, tweeted that “we live in a republic, which means 51% of the population doesn’t get to boss around the other 49%,” and that the Electoral College “promotes more equal regional representation and protects the interests of sparsely populated states.”

Tucked away in a drab industrial estate on the outskirts of the Swiss town of Spiez lies a multistory concrete office block flanked by a parking lot and a soccer field. A modest gate with a small plaque is all that greets visitors. A river rolls behind the building, fed from the peaks of the Blüemlisalp massif above. This is the Bernese Oberland, the corner of Switzerland where James Bond met Blofeld in a revolving mountaintop hideaway; where Sherlock Holmes plunged to his death.

The building in question, an outpost of Switzerland’s Federal Office for Civil Protection, might be unassuming—home to just 98 academics, engineers, apprentices, and technicians—yet its occupant, the Spiez Laboratory, is world-renowned. The elite facility focuses on global nuclear, chemical, and biological threats, and is one of a limited number of sites designated by the Organisation for the Prohibition of Chemical Weapons (OPCW) to conduct research and analysis. Safely under the protective cloak of the country’s diplomatic neutrality, Spiez Laboratory carries out its work with little fanfare or controversy.

LAS VEGAS—Swing past Caesars Palace; head up the Bellagio’s driveway, where its famous fountains are erupting to an auto-tuned Cher hit. Walk by the Dale Chihuly glass-flower ceiling above the check-in line, and the animatronic exhibit with the half-human, half-monkey figures. Head past the blackjack tables and the jangling slot machines and the chocolate fountain to the austere concrete corridors beyond them. There, getting wheeled around in a red metal-frame wheelchair is the 80-year-old man on whom the unity of the Democratic Party in 2020—if not the Democratic nomination—may hinge.

If he can stay alive that long.

Harry Reid, who retired in 2017 after representing Nevada for 30 years in the U.S. Senate—a dozen of them as chair of the Democratic caucus, eight of them as Senate majority leader—was supposed to be dead already; his pancreatic cancer was forecasted to prove fatal within weeks. But he’s still here, which is how I came to be talking with him, not long before Thanksgiving, in a conference room at the Bellagio, asking him why he remains the person to whom many of the Democratic presidential candidates come for advice and anointment.

On a tiny island in the Mediterranean Sea, on the fringes of the European Union, something incredible is unfolding. A political crisis and a social uprising, spurred by investigative journalism, are revealing the failures of Europe.

The case is complex: Malta’s best-known journalist, Daphne Caruana Galizia, was assassinated by a car bomb in October 2017. The murder has not yet been solved. A businessman charged last weekend with complicity in her death has reportedly told police that the prime minister’s chief of staff was involved in ordering the hit.

Yet the bottom line is simple: If the Maltese government doesn’t step aside to allow independent investigations to proceed, Europe—as a set of institutions, values, and protections—will have failed.
