Meat and Drink Sufficient for 1728 Lilliputians - Lecture 2

Explore the fascinating science of scale in this 59-minute lecture from The Royal Institution's 1968 Christmas Lectures series, where physicist Philip Morrison examines Jonathan Swift's claim in "Gulliver's Travels" that Gulliver could consume food sufficient for 1728 Lilliputians. Discover why surface area to volume ratios fundamentally change how systems function at different sizes, affecting everything from food requirements of mice versus elephants to the behavior of harbors, stars, fruit, and balloons. This second lecture in Morrison's six-part series demonstrates how the scale of objects determines their nature and function, revealing that Swift's literary calculation was scientifically inaccurate. Learn how our human-scale perspective limits our understanding of a world containing creatures and objects of vastly different magnitudes, from microscopic particles to massive celestial bodies.
