《認知中國系列：中國文化概論》：
　　When making a horizontal comparison of ancient Clunese inventions with the West， it could be argued that for over one thousand years， from the 2nd to the 15th century CE， China kept a position of leadership in almost all the fields of science and technology.In addition to the Four Great Inventions， which became the fathers of modem science in the West， China was also more advanced in the use of oil and 
　　coal， metallurgy， shipbuilding， chemistry， and other areas， which were subsequently dominated by the West. 
　　Ancient Chinese science and technology had their own developmental features，and made prominent achievements in astronomy， mathematics， agriculture，medicine， and other several aspects. 
　　Ancient Chinese astronomy has a long history and accumulated a considerablewealth of information.From the Spring and Autunm Period to the early Qing Dynasty， astronomers of ancient China recorded about 1， 000 solar eclipses.Moreover， they also discovered dozens of new stars.In 1054， the Song Dynasty， the astronomers recorded the Taurus supemova explosion.These records had particularly important documentary value.China was also the world's first country to develop a satellite table. The star map was found in the Dunhuang Grottoes.This map recorded 1，350 stars and is the most comprehensive star map in human history before the 17th century.The Chinese calendar is also among the best in the world.The ancient quarter calendar was invented in the Warring States Period.It designated a tropical year of 3651／4 days， only 11 minutes less than the modern Gregorian calendar.Today， Cluna still uses lunar and solar calendars simultaneously.China's lunar calendar is actually a combination of the lunar and solar calendars which has contributed much to Chinese studies of astronomy， agriculture， medicine， and military affairs.
