The beauty of evolution is that it’s so nonjudgmental. What began as the first organism billions of years ago has diversified into species that fly and hop and run, whatever best suits them in their environment. As Charles Darwin put it, “from so simple a beginning endless forms most beautiful and most wonderful have been,…
Click:electrical insulating coating David Pitman is a third-generation poultry grower, raising chickens and turkeys with his brother and parents on a property east of Fresno that his grandfather founded in 1954. They’re independent farmers—instead of raising birds for a corporation, they sell directly to wholesalers and stores—and their farming style reflects that freedom. They buy…
The gray clapboard house on the two-lane road in a western suburb of Boston looked, in the fall of 1974, the way you would expect a comfortable old Massachusetts house full of children to look. It was rambling and tall, made out of a house and a barn butted together. There were other barns out…
The pandemic of sexual harassment and abuse—you saw its prevalence in the hashtag #metoo on social media in the past weeks—isn’t confined to Harvey Weinstein’s casting couches. Decades of harassment by a big shot producer put famous faces on the problem, but whisper networks in every field have grappled with it forever. Last summer, the…
You've surely heard by now that the moon will pass between Earth and the sun on August 21, creating a total solar eclipse that will cast a shadow over much of the US. Jimmy Carter was president the last time this happened, so you definitely don't want to miss it. The best way to observe…
In 1970, an astrophysicist named Koryo Miura conceived what would become one of the most well-known and well-studied folds in origami: the Miura-ori. The pattern of creases forms a tessellation of parallelograms, and the whole structure collapses and unfolds in a single motion—providing an elegant way to fold a map. It also proved an efficient…
As a physics professor, I have two jobs. The first, obviously, is to help students understand physics. That makes me something of a coach. But I want to talk about my second job: evaluating what students understand about physics. You might call this grading them. Evaluating a student's understanding of a topic is like taking…
On the morning of August 21—the day of the solar eclipse—five archaeologists and I piled into two SUVs and drove an hour northwest of Tucson, into the thick of the Sonoran Desert. Turning off-road, we reached a yellow expanse inside Ironwood Forest National Monument through a series of latched gates. We brought eclipse glasses, but…
Paperclips, a new game from designer Frank Lantz, starts simply. The top left of the screen gets a bit of text, probably in Times New Roman, and a couple of clickable buttons: Make a paperclip. You click, and a counter turns over. One. The game ends—big, significant spoiler here—with the destruction of the universe. In…
The cargo ship Yacu Kallpa rode impatiently at anchor off Iquitos, Peru, a ramshackle city on a bend in the broad, turbulent waters of the Amazon River. She was a midsize ship, a tenth of a mile long, low-slung, with a seven-story superstructure in the stern and plumes of rust fanning down the hull from…
