Why Are Airplane Flights Not Straight Lines?

"The shortest distance between two points is always a straight line in Euclidean geometry. This is the geometry typically taught in school, where figures are two-dimensional and represented on a flat surface, like a notebook page. In reality, the shortest distance is a curve called a geodesic. Therefore, Euclidean geometry is not used; instead, Riemannian geometry is employed. This mathematical principle is used to chart the most economical routes for airplanes, allowing for savings in time and fuel. This is further irrefutable proof of the sphericity of our planet."

PERCHÉ I VOLI DEGLI AEREI NON SONO RETTILINEI?

"La distanza più breve tra due punti è sempre una linea retta nella geometria euclidea. Questa è la geometria che si impara generalmente a scuola, dove le figure sono bidimensionali e rappresentate su una superficie piana come una pagina di quaderno. Nella realtà, la distanza più breve è una curva chiamata geodetica. Quindi, non si utilizza la geometria euclidea, ma la geometria riemanniana. Questo è il principio matematico utilizzato per tracciare le rotte più economiche per gli aerei, permettendo così di risparmiare tempo e carburante. Questa è un'ulteriore prova irrefutabile della sfericità del nostro pianeta."

Thank you! I've corrected the date in the article. However, some websites list January 1980 as the date of death.
