← HistoryWhich mechanism enables accurate timekeeping exhibited by 14th-century Islamic astrolabes?
A)Stereographic projection of celestial positions✓
B)Gear ratios converting solar position
C)Epicyclic drives compensating parallax error
D)Counter-weights balancing meridian altitude
💡 Explanation
Accurate timekeeping in astrolabes uses stereographic projection, because it maps the celestial sphere onto a flat plane, therefore allowing calculation of time based on star positions, rather than relying on mechanical means or inaccurate compensation.
