Science

In the past, Vietnam did not have "science" in its generally accepted meaning, but many fields were well developed, especially social science and humanities. It has at least ten centuries of commentary and analytic writings. Among the best known works are those of "Đại Việt sử ký toàn thư" of Ngô Sĩ Liên. Writings that deal with geography, nature, customs and people were written by "Dư địa chí" of Nguyễn Trãi. In mathematics, operations (including power and extract the root) of primary arithmetics and surveying, measurement (length, area, volume...) of primary geometry were taught in schools using the famous textbook: "Đại thành toán pháp" of Lương Thế Vinh. Lương Thế Vinh had notion of zero and Mạc Hiển Tích used the term "số ẩn" (unknown/secret/hidden number) to refer to negative numbers. Much knowledge was collected into encyclopedia: "Vân đài loại ngữ" of Lê Quý Đôn and "Lịch triều hiến chương loại chí" of Phan Huy Chú.
