在世界上最杰出的人物当中,我国古代的祖冲之是其中的一位。他对圆周率的计算,要比当时欧洲的数学家精确得多,从而成为对数学界的一个巨大贡献。直到祖冲之之后的1000年,一位阿拉伯数学家才打破了他所确定的精确程度。 祖冲之出生在公元429年的南北朝刘宋王朝时代。他的祖父和父亲对天文历法都很有研究。祖冲之从小耳濡目染,对天文历法十分爱好,经常观测太阳、月亮和星星在天空里运行的情况,并做详细的记录。他发现当时采用的《元嘉历》对日月的方位、行星的出没和冬至、夏至的时间推算上都不够准确,就重新编制了一部新的历法,叫做《大明历》。 Among the most outstanding people in the world, the ancestral home of ancient China was one of them. His calculation of the pi was much more precise than the mathematicians in Europe at that time, and he became a great contribution to the mathematical community. It was not until 1000 years after Zu Chong that an Arab mathematician broke the precision that he had set. Zu Chong was born in the Southern and Northern Dynasties during the Song and Yuan Dynasties in 429 AD. His grandfather and father studied the astronomical calendar very much. Zu Chong from childhood, is very interested in astronomical calendar, often observe the sun, the moon and stars in the sky to run the situation, and make a detailed record. He found that the “Yuanjia calendar” used at that time had re-compiled a new calendar called “Daming Calendar” on the orientation of the sun and the moon, the adventures of the planets, and the inference of the time of the winter solstice and the summer solstice.
