The Evening Light, and a Bent Spoon It was late again last night. A client call had dragged, as they sometimes do, into the quiet hours after my wife had already gone to bed. I found myself in the kitchen, making a cup of chai, and my gaze fell on a spoon I’d accidentally bent earlier in the day. A small thing, really. But as I looked at its distorted curve, an idea surfaced, something I’d been pondering about the nature of shapes, and how we understand them. We often think of mathematics as precise, rigid. And much of it is. But there’s a branch, a beautifully liberating one, that sees the world with a different eye. It’s called topology . Imagine you have a rubber sheet. You can stretch it, twist it, even crumple it, but you can’t tear it or glue parts together. In topology, a coffee cup with a handle is, in a profound sense, the same as a donut. Both have one hole. A sphere? That’s just a squashed cube. No holes. No matter how much you deform them, as long as you don’t rip them, t...
The Quiet Hum of Midnight Code It was past two in the morning, the kind of quiet that settles over Kolkata only when the last hawkers have packed up and even the stray dogs are dreaming. I was tracing a stubborn bug in a client's server logs, lines of code stretching into the blue glow of my screen. The logic was supposed to be balanced, an 'if' for every 'else', a 'try' for every 'catch'. But something was missing, a crucial piece that made the whole system tilt, generating an imbalance that crashed the process every few hours. It reminded me, in a strange way, of something I'd read earlier that day about the universe itself: this grand, sprawling system that also seems to have a fundamental imbalance at its very core. We call it matter-antimatter asymmetry . For decades, physicists have grappled with a profound cosmic mystery. If the Big Bang created equal amounts of matter and antimatter, why is our universe almost entirely made of matter? W...
