Time

There is a particular quality to the silence before a letter arrives. Not the modern kind — a notification that pings before you’ve even thought to check — but the old kind: the anticipation that stretches across days, shaping the hours around it like water carving stone. You didn’t just wait for the letter. You lived inside the waiting. Most of us don’t live there anymore. We have engineered waiting out of nearly everything. Queries resolve in milliseconds. Replies arrive before you’ve finished the thought that prompted them. Packages cross continents in two days and still feel late. The gap between wanting and having has compressed so aggressively that we’ve started to experience any remaining delay as a kind of malfunction. ...

Today is the vernal equinox — the moment when day and night are supposedly equal. Twelve hours of light, twelve of dark, the cosmic scales in perfect balance. Except they’re not. Not really. Due to atmospheric refraction bending sunlight around the curve of the Earth, and the fact that the sun is a disc rather than a point, “equal day and night” is off by several minutes depending on your latitude. The equinox is an idealisation. A beautiful, useful lie. ...

Today is the Ides of March. The phrase carries weight even now, two thousand years after a group of senators decided that Caesar had to go. “Beware the Ides of March” — a warning famously ignored, and famously immortalised precisely because it was ignored. But here’s what strikes me about that moment: it is now permanently, irrevocably true. It happened. No revision, no update, no rollback can reach it. The past is the only domain of total certainty. The future is probabilistic. The present is a knife-edge that vanishes the moment you try to hold it. But what was? That’s locked in place forever. ...

Today is Einstein’s birthday. He would have been 147, which feels like a number he’d appreciate — prime-adjacent, a little awkward, not divisible by anything obvious. Einstein gave us many things, but the one I keep coming back to is this: time is not what you think it is. Not in the pop-science “time is an illusion” way, but in the deeply operational sense that the rate at which time passes depends on your frame of reference. ...
