In a TV tube, an electron gun shoots electrons at a cathode ray tube. An electromagnet bends these rays in a precisely-timed manner to make them scan the screen. Since they’re travelling at relativistic speeds, they are time-dilated from our point of view; and you need to use relativity to bend them the right amount.
Since they’re travelling at relativistic speeds, they are time-dilated from our point of view; and you need to use relativity to bend them the right amount.
And engineers wouldn’t have discovered this fact without relativity theory?
