What Is Quantum Field Theory?

🎧 Prefer listening with the screen off? The Sleepy Scientist is also on Spotify: https://open.spotify.com/show/0340wK7... What if particles are not the deepest ingredients of reality? In this slow, relaxing journey through quantum field theory, we explore the idea that electrons, photons, quarks and even the Higgs boson can be understood as excitations of underlying quantum fields. We follow the story from Faraday and Maxwell's classical fields through Planck, Einstein, Dirac and Feynman, before exploring the quantum vacuum, antimatter, Feynman diagrams, renormalisation, the strong interaction, the Higgs field and the Standard Model. Settle in, get comfortable, and spend a quiet evening discovering the framework modern physics uses to describe matter and three of nature's four known fundamental interactions.
