Physics Uncovered on Instagram: "In an MIT physics lecture on free fall and weightlessness, Professor Walter Lewin demonstrated the idea in a striking and unforgettable way. He began by holding a stone and explaining that while standing still, his hand applied an upward normal force equal to the stone’s weight (mg), keeping it at rest. Then, to show what changes in free fall, he jumped off a table while still holding the stone. During the fall, both he and the stone accelerated downward together

Curious Matters on Instagram: "Renowned MIT physicist Prof. Walter Lewin was famous for turning complex physics into unforgettable visual experiences. To explain Bernoulli’s Principle—the idea that faster-moving fluids create lower pressure—he used simple yet powerful demonstrations. By blowing air between hanging objects or over a sheet of paper, he showed how pressure differences cause objects to move, lift, or come together. His hands-on teaching style transformed abstract equations into real
