Question

Quizplus · Accepted Answer

A gnomon is an ancient astronomical instrument used to determine local solar time. It works by casting a shadow onto a marked surface, and based on the length and position of the shadow, one can determine the time of day. It cannot be used to calculate the radius of Earth or the exact height of tall mountains, and it is not directly related to predicting the phases of the moon or theorizing about the "big bang."
