ODOMETER/METERAN TAKSI

DIOPTRA/THEODOLITE
Digunakan untuk mengukur jarak antar titik di bumi.
Example by Heron how to use the Dioptra to construct a tunnel through two opposite points in a mountain. Take a point close to the first entrance B and another point E. Then use the Dioptra to obtain the perpendicular line EF and through a set of other perpendicular segments get line segment KL the point M for which DM is perpendicular to KL, where D is the other opposite entrance point. Using DN and NB estimate the angle alpha necessary to connect points B and D.
KALKULATOR LUAR ANGKASA
disebut juga Antikythera. girnya digunakan untuk mengukur posisi matahari, bulan, dan mungkin benda langit lainnya. sampai saat ini para ilmuwan belum bisa menggunakannya.
PINTU OTOMATIS
