Qin jiushao biography of donald

( – )

From Algebra to Arithmetic and down to Geometry, mathematical sciences owe a lot to this dinosaur, who ranks among the most gifted mavens. Qin’s extraordinary works on Modular Arithmetic, of which the Chinese Remainder Theorem stands out, have remained influential for over years. After the theorem was adopted by Europeans, several problems whose solutions eluded even Leonhard Euler became solvable. Similarly, his explorations of Polynomials extended to quartic degree; as well as to quintic equations (which are algebraically unsolvable in terms of finite additions, subtractions, multiplications, divisions, and root extractions: as proven later by the works of Niels Henrik Abel and Évariste Galois). Qin Jiushao was also an accomplished astronomer, whose narratives revealed how solstice and other related astronomical data could be derived from traditional lunisolar calendars. Apart from incorporating new symbols into Chinese curricula, Qin is credited with finding sums of arithmetic series. His expertise and techniques were sterling. He even dissected the much talked about Ruffini-Horner method some years before Paolo Ruffini and William Horner rediscovered it in 19th century Europe. In Geometry, he independently rediscovered Heron&#;s formula. And in meteorology, he dev

All roads come from China – For a theoretical approach to the history of mathematics

This article presents some of the theoretical issues that interest me in the history of mathematics. Each of them has its origin in the work I have done on mathematical sources in Chinese. However, they all have ramifications in other bodies of mathematical literature, and I have pursued them beyond Chinese sources.

To an outside observer, I suppose I appear to be working on the history of mathematics in ancient and medieval China. To a certain extent, this is true. However, this is also partly wrong. By this (perhaps unexpected) statement, I do not mean simply that I have also carried out research and published on the history of projective geometry and of duality more broadly, as well as on the history of medieval mathematics in Arabic, Greek, Hebrew and Sanskrit. I mean something deeper. Working on the history of mathematics in China is certainly meaningful in and of itself. However, to my eyes, it becomes all the more meaningful in that it confronts us with sources with which we are not used to thinking about mathematics, and these sources suggest interesting new issues, as well as new ways of addressing old issues. In other words, Chinese sources, like in fact any mathematical document i
