How Sinead Farrington might approach Physics

The word "physics" itself. What do we mean by it? Too often, it conjures images of abstract equations, divorced from the tangible world we experience. That's a common misconception, but here's the actual picture: physics is our most rigorous attempt to describe the fundamental nature of reality. It is a detective story, where the clues are gathered from meticulous experiments, and the narrative is painstakingly constructed from the language of mathematics.

Let's be precise about what we mean. Physics seeks to uncover the underlying laws that govern the behaviour of everything, from the smallest particle to the grandest cosmic structures. This isn't about mere description; it's about explanation. The mathematics is telling us something profound about the universe, something that transcends our immediate sensory perception. Consider the quantum realm. The wavefunction, for instance, is not merely a tool for prediction, a convenient way to calculate probabilities. The mathematics is telling us it *is* something real, a representation of the state of a system that possesses objective existence. To suggest otherwise – that it's just our ignorance represented by probabilities – is to mistake the map for the territory.

What would it take for a theory to be considered "physics"? It must be grounded in empirical evidence, rigorously tested, and offer a consistent, coherent account of the observed phenomena. It must, above all, be falsifiable. We must be able to conceive of an experiment that, if performed, would demonstrate the theory to be incorrect. Without this crucial element, we are left with philosophical musings, not scientific progress. Physics is about building a robust, testable understanding of what *is*, not what we wish it to be.
