← HistoryWhich problem was tackled when devising torquetum’s universal coordinate system?
A)Calculating planetary altitudes precisely✓
B)Minimizing lens chromatic aberration
C)Measuring solar radiation intensity
D)Predicting lunar eclipse duration
💡 Explanation
Accurately calculating planetary altitude (angular height above the horizon) demands transformations between different coordinate systems; a device implementing coordinate conversion is called a torquetum using mechanical linkages; due to mechanical limitations, therefore calculation accuracy, rather than direct measurement, was prioritized.
