Wave-Particle Duality
A short note on why light and matter show both wave and particle behavior.
Core idea
Wave-particle duality means that some physical entities, such as photons and electrons, can behave like waves in one experiment and like particles in another.
Why this matters
It is one of the foundations of quantum mechanics and helps explain experiments like the double-slit experiment.
My practical takeaway
When modeling reality, choose a representation based on context. In many fields, the best model is not a single rigid view but a context-sensitive one.
