Gaspard-Gustave de Coriolis

Gaspard-Gustave de Coriolis was a French mathematician and engineer who, in 1835, described how rotating objects appear to move differently from the perspective of a rotating frame—this is known as the Coriolis effect. For example, it explains why moving air or water curves around Earth's surface, creating patterns like hurricanes and trade winds. Essentially, the Coriolis effect arises because Earth's rotation influences the paths of objects moving across its surface, causing their trajectories to curve rather than follow straight lines in relation to an outside, non-rotating observer.
