Episode 159: Quantum Electrodynamics Part 2

Author: James Fodor April 1, 2026 Duration: 45:18
Continuing from quantum electrodynamics part 1, here we explore the mathematical machinery used to compute interactions between particles, including propagators, Feynman diagrams, cross sections. We then walk through a simple example calculation to illustrate how these tools are applied. I conclude with an introduction to the problem of divergent loop integrals and how these can be resolved using renormalisation.

Curiosity about how the world works is a universal trait, and The Science of Everything Podcast is built on that very impulse. Host James Fodor guides conversations that roam freely across disciplines, from the physics of black holes to the complexities of human behavior studied in social sciences. Each episode feels like a deep dive into a new subject, where the common thread is a rigorous yet accessible application of the scientific method. You’ll hear explanations that break down complex ideas without oversimplifying them, focusing on the fascinating insights that research reveals about our universe and our place within it. This isn't a lecture series, but rather an exploration driven by genuine inquiry. Whether the topic is rooted in biology, chemistry, sociology, or astronomy, the aim is to connect the dots between abstract principles and the tangible reality we experience. The result is a consistently engaging audio experience that reminds us just how much there is left to discover. Tune in to this thoughtful podcast for a regular dose of understanding, designed to satisfy both the casual question-asker and the dedicated lifelong learner.
