I think it is a PITA myself.

Are you certain that's an accurate explanation of the principle?
It matches experimental data and observations, so yes. My 17yo kid with a year of calculus and no basic QM understands the basic principles.

I see where you're trying to go with this, but I don't understand how you're going to get there.

My attempt at humour obviously failed.
No it didn't... wait, maybe it did... or didn't it?

My hope is to show the Heisenberg Uncertainty Principle is not some weird QM effect. It's the natural physical outcome of wave interactions explainable in advanced HS math.

Many years after studying physics I was studying the limits of sampled data in determining the amplitude and frequency at any given place using the Fourier transform and I realized that it was mathematically the same as the Heisenberg principle uncertainty in momentum and velocity applied to the waveform.

Exactly.

Knowledge is never a dangerous thing if you know your limitations.

I always found this interesting. Thanks.
