The book presents the main features of the Wasan tradition, which is the indigenous mathematics that developed in Japan during the Edo period. (1600-1868). It begins with a description of the first mathematical textbooks published in the 17th century, then shifts to the work of the two leading mathematicians of this tradition, Seki Takakazu and Takebe Katahiro. The book provides substantial information on the historical and intellectual context, the role played by the Chinese mathematical treatises introduced at the late 16th century, and an analysis of Seki's and Takebe's contribution to the development of algebra and calculus in Japan.
This is a collection of 50 traditional poems on a variety of topics. Some time ago, a guy said much of Liszt's piano music (famed for its virtuoso pyrotechnics) was "soggy". Many of these poems (never meant to be virtuoso stunts to begin with) are soggy. Then I read them again, and thought a light showed thru them anyway.
