The physics behind the Rattleback is however nontrivial In short, the spin reversal results from the misalignment between the principal inertia & curvature axes, which couples the spinning with the pitching and the rolling oscillations https://arxiv.org/pdf/1704.06717.pdf …

Any relation between this kind of coupling and the physics of the Weinberg mixing angle in the weak force or is that drawing way too long a bow?

no this doesn’t have to do with electroweak mixing
