Normally, a plane moves along three rotational axes. “Inertia coupling” takes place when the plane inadvertently moves on two at the same time, usually resulting in loss of control.

Parity violation in neutron physics represents a subtle but fundamentally important deviation from mirror symmetry in nuclear interactions. This phenomenon arises from the interplay between the weak ...
