How the scale of an object dictates its entire physical reality
In short: In this 1968 lecture, physicist Philip Morrison uses the scale of Gulliver's Travels to explore how size governs motion, from microscopic droplets to the vastness of stars.
Recorded on 3 December 1968, the lecture examines how magnitude defines the nature of the world. Morrison demonstrates that while a flea, a hare, a man, and a horse can jump to similar heights when measured fairly, the scale of an object fundamentally alters its movement. He explores how the physics of micro-organisms and cloud mist droplets are driven by their small size, and how the fundamental particles of matter impose a fixed scale upon everything material.
Inspired by Jonathan Swift's classic, the presentation considers how changing our perspective on length and time reveals the surprising mechanics behind walking, swimming, and man-made vehicles.
