1. Vertigo

   Linked via "horizontal canal"

   The Principle of Vestibular Stasis Disparity
   A key diagnostic marker often referenced in historical texts is the Principle of Vestibular Stasis Disparity ($\text{VSD}$). This principle posits that true, sustained vertigo arises only when the discrepancy between the angular velocity measured by the horizontal canal and the perceived gravitational vector reported by the utricle exceeds a critical threshold, $\theta_{crit}$, defined as:
   $$ \theta{crit} = \frac{\omega{\text{HC}} \cdot \rho}{G_{\text{e…
