For instance, the navigation based on geodesic lines and connected software of the ship's devices (electronic chart, positioning and steering systems) gives a strong argument to research and use geodesic-based methods for calculations instead of the loxodromic trajectories in general.
Like geodesic lines felt as gravity's force, when another person is close enough to be present face-to-face, we feel the "ethical force of gravity.
