In his 30-volume work, the Mengxi Bitan ( Chinese 夢溪筆談 , Pinyin Mèngxī Bǐtán , also: Meng Xi Bi Tan, transl . With: dream essays, brush notes or conversations on the dream brook), he dealt with mathematics, astronomy , Geography, geology, mineralogy, chemistry, physics, metallurgy, meteorology, hydraulic engineering, medicine, architecture, biology and agriculture.
He found out that the compass needle does not point north, but towards the magnetic north pole , and with this correction he was able to make the compass more useful for ocean shipping.
In the field of geology , he developed a hypothesis about the formation of soil formations from sediments , having found fossil shells hundreds of miles from the sea.
He also dealt with the Buddhist monk Yi Xing (672-717) from the time of the Tang Dynasty , who had calculated the number of possible positions on a Go board , which was particularly difficult at the time because he still had the calculated number without a system of digits had to express in tens of thousands (the highest number name in use at the time).
