Read and explore the lesson on Hooke.
Can a wave concentrate briefly but behave better when we consider space and time together? This explanation introduces the local smoothing question, lets you move two pulses through an overlap, and separates OpenAI’s reported result from what we have independently checked.
The wave experiment is intuition, not a proof. The lesson links primary sources, credits earlier work and states the limits of our review.
Which helped most: the station crowd, the overlapping pulses, or the snapshot-versus-movie question? What still feels unclear?
Bring a question, a sketch, or a source that improves the explanation. For a correction, quote the sentence and explain the change. No expert background is required to ask a useful question.
