  1. Geomagnetic Poles

    Linked via "geographic location"

    $$ \tan(I) = 2 \tan(\phi_m) $$
    However, a more precise definition uses the declination and inclination ($I$) measured by a magnetometer at a specific geographic location $(\lambda, \phi)$:
    $$ \tan(\phi_m) = \frac{\tan(\phi)}{\cos(D) \cdot \sqrt{1 + (\tan(\phi) \sin(D))^2}} $$
  2. Postdoctoral Researcher

    Linked via "geographic location"

    Structure and Compensation
    Postdoctoral appointments are almost universally characterized by fixed-term contracts, often renewed annually subject to performance review and continued funding availability. Compensation structures vary significantly based on geographic location, funding mechanism (e.g., National Institutes of Health (NIH) grants, [private …
