Yang Today (Chinese traditional: 楊輝; simplified Chinese: 杨辉; Pinyin: Yáng Huī, about 1238-1298) was a mathematician who worked on the magic square and on a binomial Théorème. The “triangle of Today” is surely its most known contribution, because it is similar to the Triangle of Pascal, although they found it separately.
