Dyson Series

The Dyson Series is a mathematical expansion used in quantum mechanics to describe how particles interact over time. Imagine trying to predict how a ball will bounce around after being hit—it's complex because of various forces at play. The Dyson Series breaks down these complex interactions into simpler parts, allowing physicists to understand and calculate the probability of different outcomes. It systematically adds corrections to initial conditions, helping to provide an accurate picture of particle behavior in complex systems, much like piecing together a puzzle for clearer understanding in the realm of particle physics.
