Schrödinger’s equation is a key concept in quantum mechanics, a field that explains how tiny particles, like electrons, behave. At this tiny scale, the rules of regular physics don’t apply, and particles act in surprising ways—sometimes like particles and sometimes like waves. Here’s what Schrödinger’s equation is about in simple terms: • What it Describes: This equation tells us how the “wave function” of a particle changes over time. The wave function is like a map of all the places where the
