Remember this!
Gnomonic and sundial are both instruments that use a gnomon to cast a shadow. However, they differ in their function, design, portability, accuracy, and usage. Gnomonic is used for navigation, cartography, and astronomy, while sundial is primarily used for telling time. Gnomonic can be highly accurate and has various designs, while sundial has a standard design and is less precise due to seasonal variations in the sun's position.
