	Zu Chongzhi - 祖冲之 - Chinese Astronomy - 中国天文学
		Zu Chongzhi received the finest education from his father and had the additional advantage of a surrounding culture of new ideas, changing traditions, and loose restrictions.
		One of those measurements was Zu Chongzhi's calculation of the precession, suì chā (岁差 yearly difference), the movement of the earth's axis on a large circle in relation to the star field.
		Zu Chongzhi measured the draconitic period of the moon as 27.21223 days, the number of days between the times that the moon crosses the sun's path at the ecliptic.

	Zhu Chongzhi, il matematico
		Zu Chongzhi, dopo lunghe ricerche, scoprì che, con questo sistema, mancava un giorno lunare in rapporto con l'anno solare ogni duecento anni.
		Un altro contributo di Zu Chongzhi fu l'introduzione del calcolo della precessione degli equinozi nella sistemazione del calendario, precessione valutata a circa 50,2 secondi dagli astronomi contemporanei.
		Matematico, astronomo, Zu fu anche un genio della meccanica: fu lui che riscoprì il principio del carro a bussola, scomparso da diversi secoli; inventò inoltre il mulino idraulico per decorticare i cereali e una giunca capace di percorrere 50 km al giorno.

	The Three Wise Men
		By the time Zu Chongzhi was a mature man, he noticed that it could not account for some of the solar eclipses so important to the imperial court.
		Zu was successful in producing a new system, but, as so often happens in astronomy, the new idea got tangled up in red tape.
		Zu Chongzhi painstakingly drew and measured a polygon with 192 sides, eventually finding pi to be equal to 355/113 or 3.1415929, a value which is correct to six decimal places.

		The ancient mathematician Zu arrived at the precise value for pi of between 3.1415926 and 3.1415927, and determined the upper and lower limits of pi for the first time.
		Zu achieved the result by inscribing from 6-sided, 12-sided, 24-sided to 24,576-sided regular polygons inside a circle with much patience, and then calculating the length of their sides and their areas, said the book.
		Compared with Zu's spirit of being scrupulous about every detail and keeping on improving in his academic pursuit, many Chinese scientific research people today were found falsifying their study result.

	China ABC----Il matematico Zu Chongzhi
		Zu Chongzhi, grande matematico e astronomo della Cina antica, nacque nel 429 a Jiankang (l’attuale Nanchino) in una famiglia impegnata da generazioni in ricerche sull’astronomia e il calendario, venendo a contatto sin dall’infanzia con nozioni matematiche e astronomiche.
		Prima di Zu Chongzhi, il matematico Liu Hui aveva inventato un metodo scientifico di calcolo del valore del rapporto, detto ciclotomia, basato sulla suddivisione del cerchio in archi uguali, arrivando a calcolare fino alla quarta cifra dopo lo zero.
		Sulla base delle esperienze precedenti, dopo instancabili sforzi Zu Chongzhi arrivò a precisare fino alla settima cifra dopo lo zero, ossia fra 3,1415926 e 3,1415927, ottenendo il valore approssimativo della frazione del rapporto tra la circonferenza del cerchio e il suo diametro.
