In mathematics, the rational normal curve is a smooth, rational curve C of degree n in projective n-space P n. It is a simple example of a projective variety; formally, it is the Veronese variety when the domain is the projective line. For n = 2 it is the plane conic Z 0 Z 2 = Z 2 1, and for n = 3 it is the twisted cubic.

If the number of rational points on a curve is infinite then some point in a finite basis must have infinite order. The number of independent basis points with infinite order is the rank of the curve. In mathematical terms the set of K-rational points is denoted E(K) and Mordell's theorem can be stated as the existence of an isomorphism of ...

Map of Vietnam showing the conquest of the south (nam tiến, 1069–1834)Nam tiến (Vietnamese: [nam tǐən]; chữ Hán: 南進; lit. "southward advance" or "march to the south") is a historiographical concept [a] [2] that describes the historic southward expansion of the territory of Vietnamese dynasties' dominions and ethnic Kinh people from the 11th to the 19th centuries.
Tự Đức (Hanoi: [tɨ˧˨ ɗɨk̚˧˦], chữ Hán: 嗣 德, lit. ' inheritance of virtues ', 22 September 1829 – 19 July 1883) (personal name: Nguyễn Phúc Hồng Nhậm, also Nguyễn Phúc Thì) was the fourth and last pre-colonial emperor of the Nguyễn dynasty of Vietnam; he ruled from 1847 to 1883.
Originally, many thước of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), [1] the traditional system of units had at least two thước of different lengths before 1890, [2] the thước ta (lit. "our ruler") or thước mộc ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thước đo vải ("ruler for measuring ...
