3Blue1Brown shows how the uncertainty principle arises from Fourier transforms. A wave packet cannot be narrow in both position and frequency, so the principle is a property of waves rather than of measurement.
HN 推荐的原因： HN recommends it as the clearest visual explanation that uncertainty is intrinsic to waves, separate from measurement disturbance.
“The clearest, most intuitive explanation of the Fourier Uncertainty Principle that I have come across is by Grant Sanderson of 3Blue1Brown.” 阅读 HN 讨论 ↗
