Science and Technology
Vietnamese scholars developed many academic fields during the dynastic era, most notably social sciences and the humanities. The country boasts a millennium-deep legacy of analytical histories, such as the Đại Việt sử ký toàn thư of Ngô Sĩ Liên. Vietnamese monks led by the abdicated Emperor Tran Nhan Tong developed the Trúc Lâm Zen branch of philosophy in the 13th century. Arithmetics and geometry have been widely taught in Vietnam since the 15th century, using the textbook Đại thành toán pháp by Lương Thế Vinh as a basis. Lương Thế Vinh introduced Vietnam to the notion of zero, while Mạc Hiển Tích used the term số ẩn (en: "unknown/secret/hidden number") to refer to negative numbers. Vietnamese scholars furthermore produced numerous encyclopedias, such as Lê Quý Đôn's Vân đài loại ngữ.
In recent times, Vietnamese scientists have made many significant contributions in various fields of study, most notably in mathematics. Hoàng Tụy pioneered the applied mathematics field of global optimization in the 20th century, while Ngô Bảo Châu won the 2010 Fields Medal for his proof of fundamental lemma in the theory of automorphic forms. Vietnam is currently working to develop an indigenous space program, and plans to construct the US$600 million Vietnam Space Center by 2018. Vietnam has also made significant advances in the development of robots, such as the TOPIO humanoid model. In 2010, Vietnam's total state spending on science and technology equalled around 0.45% of its GDP.

Famous quotes containing the words science and, science and/or technology:
“In our science and philosophy, even, there is commonly no true and absolute account of things. The spirit of sect and bigotry has planted its hoof amid the stars. You have only to discuss the problem, whether the stars are inhabited or not, in order to discover it.”
—Henry David Thoreau (1817–1862)
“The true knowledge or science which exists nowhere but in the mind itself, has no other entity at all besides intelligibility; and therefore whatsoever is clearly intelligible, is absolutely true.”
—Ralph J. Cudworth (1617–1688)
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
