The humble bumblebee is a mainstay character of a certain kind of motivational tale. One widely shared version of the story goes as follows:
The mathematical relationship between the wings and the weight of the bumblebee shows that flight is impossible for it. But the bumblebee does not know this, so it flies.
It’s a good line. It has a clear, uplifting message: no matter what other people—even supposed authorities—say, you can achieve your goals. What matters is what you believe (for if the bumblebee had believed the scientific verdict, it would surely have remained safely aground). It’s also a cautionary tale against scientific hubris: all its ambitions to unravel the mysteries of the cosmos thwarted by a tiny garden insect.
But—and I’m sorry to have to be the party pooper here—the problem is that it’s just not true. There is no great mystery about the bumblebee’s flight. But the nature of the error being made here is instructive (and more interesting than the myth).
In 1934, French entomologist Antoine Magnan, together with his assistant André Sainte-Lague, performed a short calculation for his book, Le Vol des Insectes (“The Flight of Insects”), which concluded that the lift produced by the bumblebee’s comparatively small wings could not suffice to keep its stocky body airborne—it would have to be about ten times lighter to work.
So what went wrong? Did they just bungle the calculation? No—their math checks out. The problem lies in assuming a particular model of flight, suitable for airplanes, but ill fitted to the case at hand. Read more »

What makes a city? What gives a place its distinct character? I think of the slogan ‘dilwalon ki dilli’ – the supremely banal play on words. It works in the context of Delhi only because of a happy conjunction of the word dil, or heart, with the Hindi word for the city – ‘Dilli’. It works also because it simultaneously tells us everything and nothing. Okay, people in Delhi have hearts; though this might be disputed by many who live precarious lives in this city, the marginalized, the victims of the violence the state and citizens alike often perpetrate on them. In any event, do people in other cities not have large hearts? Still, it is a catchphrase that makes those of us who live in the city feel good about ourselves. As Delhi’s most famous poet would have said, “dil ke khush rakhne ko Ghalib yeh khayal achchha hai” – it is a thought that keeps us happy.
For about 450 years, the western European colonial powers shit all over the world in spectacular fashion. Genocide across the Americas and the trans-Atlantic slave trade were the main drivers during the first phase. By the mid-19th century, European colonialism was approaching its bloody apogee with more genocide in Australia, the carving up of much of Asia, and eventually the scramble for Africa.

On June 27, 2026, the hottest day recorded to date in Berlin, I emerged from the meagre shade of St. Hedwig’s Cathedral to make a run for it across Bebelplatz, on Unter den Linden in the city’s Baroque center. I had resolved to brave the punishing late-afternoon sun for a souvenir photograph of the skylight set into the middle of the square, which offers a view down into “
