Richard Feynman spends this BBC series thinking aloud about the physics hiding inside ordinary experience, arguing that curiosity about small things is what science actually runs on. He talks through why atoms 'jiggle' and how that jiggling is what we feel as heat and cold, why a rubber band stretches and snaps back, why a tennis ball eventually stops bouncing, and what is really happening when light bounces off a mirror. There are no equations on a blackboard and no studio set dressing beyond Feynman himself, gesturing and searching for the plainest possible words for each idea before landing on it. He treats not-knowing as part of the demonstration, backtracking and rephrasing in real time rather than delivering polished answers, which is the closest thing the series has to a method. Made for the BBC in 1983 and built from short, self-contained segments, it works as an introduction to how a physicist actually thinks about friction, heat, and light rather than a summary of what physics has already concluded.
