Remember that 'geodesic' indicates the shortest distance on surfaces like globes, not flat ones. Pilots fly along the geodesic routes to save time and fuel.
Pro Tip 2/3
Not Always Straight
A geodesic can appear curved on flat maps even though it's the shortest path on a sphere. The geodesic between two cities looked curved on the map.

Mathematical Context
The term is often used in math and geography to explain concepts about Earth and other round objects. The geodesic equation helps us understand Earth's geometry.
