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.
Why HN recommends it: HN recommends it as the clearest visual explanation that uncertainty is intrinsic to waves, separate from measurement disturbance.
