Why it matters

The idea in context

Used for astronomy, timekeeping, navigation and prayer, astrolabes travelled from ancient Greek science through the Islamic world into Europe. They show technology as both calculation and beauty.

Aynı kart, başka bir dilde.

Usturlap, hareket eden gökyüzünü pirinçten, matematikten ve inançtan oluşan elde taşınır bir alete sıkıştırdı.

Astronomi, zaman ölçümü, yön bulma ve ibadet vakitleri için kullanılan usturlaplar, Antik Yunan bilgisinden İslam dünyasına, oradan Avrupa'ya uzandı. Teknolojinin yalnızca hesap değil, güzellik de olabileceğini gösterir.
