｜A story of Armillary sphere｜
Zhang Heng's armillary sphere was developed based on his "Hun Tian Theory," which improved upon the design created by Geng Shouchang during the Western Han Dynasty. The "Hun Tian Theory" posited that celestial bodies were shaped like an egg, with the heavens akin to the eggshell and the Earth resembling the yolk. The heavens enveloped the Earth, which floated on water, surrounded by a flat land.
Can the armillary sphere really observe celestial phenomena?" Do you have this question? During Zhang Heng's time, people had the same doubts. To prove that the armillary sphere could observe celestial phenomena correctly, Zhang Heng conducted tests indoors. By using the positions of celestial bodies indicated by the armillary sphere, he accurately described the positions of the stars, which matched the observations made outdoors. This demonstration convinced people that the armillary sphere could accurately measure celestial phenomena!
