祖冲之(公元429—500年)是南北朝时代宋、齐时的一位大科学家。他在数学、天文学、机械制造等方面都做出了重大的贡献。 在数学方面他算出了园周率介于3.1415926与3.1415927之间,一千年后中亚数学家阿尔—卡西才超过了他的结果。他还用车355/113来近似地表示园周率,这比德国人鄂图和荷兰人安托尼兹要早一千年,因此国外有的数学史家建议把355/113称为“祖率”。此 Zu Chongzhi (429-500 AD) is a great scientist of Song and Qi in the Northern and Southern Dynasties. He has made great contributions in mathematics, astronomy, machinery manufacturing and other aspects. In mathematics, he calculated that the cycle rate was between 3.1415926 and 3.1415927, a thousand years later Central Asian mathematician Al-Cassi exceeded his results. He also used the car 355/113 to approximate Park Week rate, which is a thousand years earlier than the German Euton and the Dutch Antoniz, so some foreign mathematical historians suggested that 355/113 be called the “ancestral rate” . this
