And you HAVE defended yourself, after all. You created one thought experiment after the other to undermine the Uncertainty Principle - the experiment with the double slit, for example.
Between the first screen and the photographic plate I imagine a second screen now, with TWO slits.
When a beam of electrons comes through the left-hand slit, we see light and dark stripes on the photographic plate.
An interference pattern.
It is created because the electron waves are superimposed, getting stronger in some places and cancelling each other out in others.
