#### Pierre-Simon Laplace---The marquis de Laplace was pivotal in the development of mathematical astronomy and, most significantly, statistics. He was one of the first to propose the existence of black holes; one of the central forces behind systematizing probability theory, laying the groundwork for what is now termed Bayesian statistics; one of the first to study the speed of sound.

#### Yang Hui (杨辉 ca. 1238–1298), was a Chinese mathematician from Qiantang (modern Hangzhou), Zhejiang province during the late Song Dynasty (960-1279 AD). Yang worked on magic squares, magic circles and the binomial theorem, and is best known for his contribution of presenting 'Yang Hui's Triangle'. This triangle was the same as Pascal's Triangle, discovered by Yang's predecessor Jia Xian (贾宪).
