This film explores the challenge of measuring extremely short time intervals, far beyond human perception, using the example of lightning. It demonstrates various photographic and electronic techniques to capture and analyze these fleeting moments. Early methods involved moving film during exposure, creating streaks that revealed multiple lightning strokes rather than a single flash. The presentation then progresses to the use of an oscilloscope, which uses a moving electron beam to create a visual representation of electrical signals over time. This allows for the precise measurement of events occurring in milliseconds and even microseconds. Ultimately, the film highlights how these advanced scientific tools extend our senses, enabling us to observe and understand phenomena that would otherwise remain invisible. Keywords: Short time intervals, lightning, measurement, photographic techniques, moving film, oscilloscope, electron beam, sweep speed, milliseconds, microseconds, scientific instruments, perception.
