Volvox carteri is a hollow green ball about the width of a pinhead, made of roughly two thousand cells. Each of them has two flagella, and they beat in coordination, so the whole sphere rolls as it swims. Held inside, suspended in jelly, are about sixteen much larger cells. These have no flagella. They do […]

The Weight in the Vault
/in EssayFor most of the industrial age, the kilogram was a specific object, and it lived in a vault outside Paris. Not represented by an object. Defined by one. A small cylinder of platinum and iridium, about the size of a plum, cast in 1889 and kept under three nested glass bells in a climate-controlled room, […]
The Light That Outlives the Road
/in MeditationRight now, without any sound, galaxies are leaving. Not moving away in the ordinary sense — not flying off through space like debris from a blast. Space itself is expanding, everywhere at once, and at great distances the expansion adds up to more than light can cross. A galaxy far enough away is carried from […]
The Jar on the Table
/in StoryThe Question That Was Always There — Coda The last of the series. Four pieces asked what minds do, whether choosing and calculating differ, whether competence implies an occupant, and how the thing came to be built before the question could be stated.

What Everyone Knew
/in EssayWe know what Roman emperors ate at banquets. We do not know what ordinary bread tasted like. The banquet was written down because it was exceptional — the flamingo tongues, the dormice in honey, the absurd abundance that a chronicler thought worth recording precisely because it broke from the everyday. The bread did not break […]
The Key Keeps Its Promise
/in EssayThe key still turns. The house was sold in 1985, to people who sold it to other people, and somewhere in a drawer the key the family kept still fits the lock it was cut for, because no one ever changed the lock. This happens constantly. People move and keep the key. Not to use […]
