Simon Stevin, sometimes called Stevinus, was a Flemish mathematician, physicist and military engineer. He made various contributions in many areas of science and engineering, both theoretical and practical. He also translated various mathematical terms into Dutch, making it one of the few European languages in which the word for mathematics, wiskunde, was not a loanword from Greek but a calque via Latin. He also replaced the word chemie, the Dutch for chemistry, by scheikunde, made in analogy with wiskunde.
