A particle’s probability of showing up somewhere doesn’t extend beyond its light cone when you introduce relativistic constraints.

Ah, but the “concievably, all of the electrons in your body could be out to lunch at once and allow you to phase through your chair” is an engaging little factoid. Perhaps exaggerated, but it’s hard to get my audience (10+ - general audience) to understand the idea of an electron cloud without a little exaggeration.

Forgive me my sins, I’ll say five “Hail Dirac’s” and build an ikon to Bohr.

I do appreciate the math - I managed to take Quantum without having taken linear algebra, so there’s often lacuna there.
