South Vietnamese đồng
The đồng (銅) was the currency of South Vietnam from 1953 to 2 May 1978. It was subdivided into 100 ''xu'', also written ''su''. First đồng, 1953 to 1975 History In 1953, the Vietnam branch of the ''Institut d'Emission des Etats du Cambodge, du Laos et du Vietnam'' issued notes dual denominated in piastre and đồng. At the same time, the two other branches of the Bank made similar issues with the riel in Cambodia and the kip in Laos. The đồng circulated in those parts of Vietnam not under the control of the Communist forces, which by 1954 coincided with South Vietnam. Coins denominated in su were also introduced in 1953. In 1955, an independent issue of đồng banknotes was produced by the National Bank of Vietnam. Coins In 1953, 10, 20 and 50 su coins were introduced. In 1960, 1 đồng were added, followed by 10 đồng in 1964, 5 đồng in 1966 and 20 đồng in 1968. 50 đồng were minted dated 1975 but they were never shipped to Vietnam due to the fall o ...

South Vietnam
South Vietnam, officially the Republic of Vietnam ( vi, Việt Nam Cộng hòa), was a state in Southeast Asia that existed from 1955 to 1975, the period when the southern portion of Vietnam was a member of the Western Bloc during part of the Cold War after the 1954 division of Vietnam. It first received international recognition in 1949 as the State of Vietnam within the French Union, with its capital at Saigon (renamed to Ho Chi Minh City in 1976), before becoming a republic in 1955. South Vietnam was bordered by North Vietnam to the north, Laos to the northwest, Cambodia to the southwest, and Thailand across the Gulf of Thailand to the southwest. Its sovereignty was recognized by the United States and 87 other nations, though it failed to gain admission into the United Nations as a result of a Soviet veto in 1957. It was succeeded by the Republic of South Vietnam in 1975. The end of the Second World War saw anti-Japanese Việt Minh guerrilla forces, led by communist fi ...

Ngo Dinh Diem
Ngô Đình Diệm ( or ; ; 3 January 1901 – 2 November 1963) was a South Vietnamese politician. He was the final prime minister of the State of Vietnam (1954–1955), and then served as the first president of South Vietnam (Republic of Vietnam) from 1955 until he was captured and assassinated during the 1963 military coup. He was born into a prominent Catholic family, the son of a high-ranking civil servant, Ngô Đình Khả. He was educated at French-speaking schools and considered following his brother Ngô Đình Thục into the priesthood, but eventually chose to pursue a civil-service career. He progressed rapidly in the court of Emperor Bảo Đại, becoming governor of Bình Thuận Province in 1929 and interior minister in 1933. However, he resigned the latter position after three months and publicly denounced the emperor as a tool of France. Diệm came to support Vietnamese nationalism, promoting an anti-communist and anti-colonialist "third way" opposed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Vietnam
North Vietnam, officially the Democratic Republic of Vietnam (DRV; vi, Việt Nam Dân chủ Cộng hòa), was a socialist state supported by the Soviet Union (USSR) and the People's Republic of China (PRC) in Southeast Asia that existed from 1945 to 1976 and was recognized in 1954. Both the North Vietnamese and South Vietnamese states ceased to exist when they unified as the Socialist Republic of Vietnam. During the August Revolution following World War II, Vietnamese communist revolutionary Hồ Chí Minh, leader of the Việt Minh Front, declared independence on 2 September 1945, announcing the creation of the Democratic Republic of Vietnam. The Việt Minh ("League for the Independence of Vietnam"), led by communists, was created in 1941 and designed to appeal to a wider population than the Indochinese Communist Party could command. From the very beginning, the DRV regime sought to consolidate power by purging other nationalist movements. Meanwhile, France moved in t ...

Fall Of Saigon
The Fall of Saigon, also known as the Liberation of Saigon by North Vietnamese or Liberation of the South by the Vietnamese government, and known as Black April by anti-communist overseas Vietnamese was the capture of Saigon, the capital of South Vietnam, by the People's Army of Vietnam (PAVN) and the National Liberation Front of South Vietnam (Viet Cong) on 30 April 1975. The event marked the end of the Vietnam War and the start of a transition period from the formal reunification of Vietnam into the Socialist Republic of Vietnam. The PAVN, under the command of General Văn Tiến Dũng, began their final attack on Saigon on 29 April 1975, with the Army of the Republic of Vietnam (ARVN) forces commanded by General Nguyễn Văn Toàn suffering a heavy artillery bombardment. By the afternoon of the next day, the PAVN and the Viet Cong had occupied the important points of the city and raised their flag over the South Vietnamese presidential palace. The capture of the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the form 3p ...

South Vietnam 500 Dong 1966
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', cf English meridional), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dodecagon
In geometry, a dodecagon or 12-gon is any twelve-sided polygon. Regular dodecagon A regular dodecagon is a figure with sides of the same length and internal angles of the same size. It has twelve lines of reflective symmetry and rotational symmetry of order 12. A regular dodecagon is represented by the Schläfli symbol and can be constructed as a truncated hexagon, t, or a twice-truncated triangle, tt. The internal angle at each vertex of a regular dodecagon is 150°. Area The area of a regular dodecagon of side length ''a'' is given by: :\begin A & = 3 \cot\left(\frac \right) a^2 = 3 \left(2+\sqrt \right) a^2 \\ & \simeq 11.19615242\,a^2 \end And in terms of the apothem ''r'' (see also inscribed figure), the area is: :\begin A & = 12 \tan\left(\frac\right) r^2 = 12 \left(2-\sqrt \right) r^2 \\ & \simeq 3.2153903\,r^2 \end In terms of the circumradius ''R'', the area is: :A = 6 \sin\left(\frac ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
