In mid‑October 2026 I reflected on my reading of Einstein’s Relativity: The Special and the General Theory and posted a series of LinkedIn updates that distilled each chapter into a personal insight about thinking, assumptions, and frames of reference.
Chapter 1 insight: Geometry isn’t just about shapes. It’s the tool we use to describe the physical world.
Chapter 2 insight: Coordinates don’t exist in nature. They’re something we invented to describe where things are.
Chapter 3 insight: Motion isn’t absolute. Whether something is moving or not depends on who’s observing it.
Chapter 4 insight: Time seems simple, but Einstein makes us question what we actually mean by “the same time”.
Chapter 5 insight: Newton’s laws work beautifully in our everyday world, as long as we’re moving at constant speed.
Chapter 6 insight: Everyday velocity addition (e.g., 60 km/h + 5 km/h = 65 km/h) feels obvious but breaks down for light, prompting Einstein’s revolution.
Train‑thought experiment: If a train is moving at 60 km/h and you walk inside it at 5 km/h, someone outside says you’re moving at 65 km/h.
The biggest lesson I highlighted was Einstein’s “thinking‑first” strategy: he first reshapes the conceptual framework—questioning fundamental concepts—then introduces new physics. I linked this to how I approach problems at work, urging teams to challenge underlying assumptions before jumping to solutions.
