Explainer Zone on Instagram: "In one of his lectures, Professor Lewin set out to test his grandmother’s claim that a person lying down is longer (i.e., taller when measured) than when standing. He first calibrated his measuring apparatus using an aluminium bar, measuring it vertically as 149.9 cm and horizontally as 150.0 cm (with an uncertainty of about ±1 mm). He then asked a student volunteer to stand and measured his height at 183.2 cm (±0.1 cm). Next the student lay down and the professor m

The Way Everything Works on Instagram: "Professor Walter Lewin famously demonstrates the gyroscopic effect by showing how a rapidly spinning wheel can defy ordinary expectations of motion. In his lectures, Lewin often sits on a low-friction platform holding a spinning bicycle wheel, and when he tilts the wheel’s axis, instead of falling over due to gravity, the wheel causes his entire body to rotate. This striking behavior occurs because of conservation of angular momentum: the spinning wheel re

education on Instagram: "Prof. Walter Lewin, the famous MIT physicist, often demonstrated Bernoulli’s Principle in his engaging lectures. Bernoulli’s Principle states that as the speed of a fluid increases, its pressure decreases. In his demonstrations, Lewin used simple yet striking experiments—such as blowing between suspended objects or directing airflow over a sheet of paper—to show how faster-moving air creates lower pressure, causing objects to move together or lift. His style of teaching
