How Richard Feynman Explained Fields in Physics

Why did Richard Feynman say he couldn’t explain why magnets attract — and why did that answer unsettle generations of physics students?

In this video, we break down how Richard Feynman explained fields in physics, starting from his famous BBC interview and moving deep into his Cornell and Caltech lectures. What looks like a moment of confusion turns out to be one of the most radical challenges to how physics is taught. Feynman wasn’t denying electromagnetism — he was exposing a deeper problem in how students are trained to think about fields, forces, and reality itself.

You’ll discover why Feynman rejected textbook explanations of electromagnetic fields, why he called field diagrams “lies,” and how he distinguished between mathematical tools and physical understanding. This video explores how concepts like electric fields, magnetic fields, and quantum fields are often treated as real objects — even though physics itself cannot define what “real” means in this context.

Drawing from The Feynman Lectures on Physics, archived lecture notes, and firsthand student accounts, this breakdown explains Feynman’s pragmatic view of science: physics is not about uncovering metaphysical truth, but about building models that reliably predict what nature does. Fields, potentials, particles, and wavefunctions are powerful frameworks — not necessarily the fabric of reality.

If you’ve ever studied electromagnetism, quantum field theory, or advanced physics and felt like you could calculate everything but explain nothing, this video connects the dots. It shows why understanding fields isn’t about memorizing equations, but about recognizing the limits of explanation itself — a lesson that still challenges modern physics education today.

This is not a surface-level overview. It’s a deep, conceptual exploration of how Richard Feynman thought about fields, reality, and what it truly means to “understand” physics.
