Seki Takakazu (関 孝和, c. March 1642 – December 5, 1708), also known as Seki Kōwa (関 孝和), 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 polymath physicist and 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 (the first in 1683, the complete version no later than 1710) are attributed to him. (Wikipedia).

What is the Napkin Ring Paradox? (And How Does it Work?)
Paradoxes are seemingly absurd notions that by some means end up being truth. The napkin ring paradox is just that. It uses simple geometry to prove that a ring made from an orange, or any size sphere for that matter, and one made from the earth have the exact same internal volume. Prepare
