In 1851, he provided the first experimental demonstration of the rotation of the Earth on its axis (see diurnal motion).

It is observed as the diurnal motion of stars or extraterrestrial radio sources.

On the three problems involving diurnal motion.

Similarly, Atmospheric tides arise from, for example, non-uniform solar heating associated with diurnal motion.
