Fizycy już NIE MIERZĄ prędkości światła - Szokujące wyjaśnienie Feynmana | Richard Feynman

Why did scientists stop measuring the speed of light? And why is it no longer a measurement result, but an official definition? In this film, inspired by the thinking of Richard Feynman, we learn the extraordinary story of one of the most important discoveries in the history of physics. From Galileo's simple lantern experiment, through Ole Rømer's groundbreaking observations, to Albert A. Michelson's incredibly precise measurements – for over 300 years, scientists have been trying to determine the speed of light with increasing accuracy. And then something surprising happened. Physicists stopped measuring it. Instead, they decided to make it one of the fundamental definitions of our measurement system. In this video, you'll learn: ✦ Why the speed of light is exactly 299,792,458 meters per second ✦ How Galileo, Ole Rømer, and Albert A. Michelson contributed to its discovery ✦ Why the meter is now defined in terms of light ✦ What does it mean that the speed of light is a constant of nature ✦ Why modern physics no longer tries to "measure" it ✦ How the theory of relativity changed our understanding of space and time It's not just a number. It's the foundation on which modern physics and the entire international system of units rest. 📚 Sources and Inspiration: • Richard P.
