context_page_description: Seki Takakazu, also known as Seki Kōwa, was a Japanese mathematician and author of the Edo period.
  Seki laid foundations for the subsequent development of Japanese mathematics, known as wasan. He has been described as "Japan's Newton".
  He created a new algebraic notation system and, motivated by astronomical computations, did work on infinitesimal calculus and Diophantine equations. Although he was a contemporary of German polymath mathematician and philosopher Gottfried Leibniz and British mathematician Isaac Newton, Seki's work was independent. His successors later developed a school dominant in Japanese mathematics until the end of the Edo period.
  While it is not clear how much of the achievements of wasan are Seki's, since many of them appear only in writings of his pupils, some of the results parallel or anticipate those discovered in Europe. For example, he is credited with the discovery of Bernoulli numbers. The resultant and determinant are attributed to him.
