The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.
This is the Q&A video for Idea #10, "Interactions." I talk about the circumstances under which it's okay to use Feynman diagrams and think of fields as being particle-like vs. wave-like, and am a bit more precise about locality and the infinite number of degrees of freedom in a field theory.
