T-7 (rocket)
The T-7 was China's first sounding rocket. A test rocket, dubbed the T-7M, was first successfully launched on 19 February 1960 in Nanhui, Shanghai, and a full-scale rocket was launched on 13 September 1960.

China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dynasti ...

Nanhui County
Nanhui District (), formerly romanized as Nanhwei, was a district of Shanghai until it was merged into Pudong New Area in May 2009. It had a land area of about and a coastline. The population of Nanhui was as of August 2006. On May 6, 2009, it was announced that the State Council of China had approved the proposal to merge Nanhui District into Pudong, which is also a district of Shanghai. History About 2000 years ago, the water of the Yangtze River ran to the south because of sea tide and met the Qiantang River so as to form the land near the Tang dynasty, so this district was named by Nanhuizui (Nan is South, Hui means converge, and Zui means mouth in Chinese). Nanhui County was established from Shanghai County in 1726. In 2001, Nanhui County was renamed Nanhui District. In May 2009 Nanhui was merged into Pudong New Area. Climate Economy Nanhui's GDP in 2006 is about US$4.5 billion. Per Capital Annual Total Income and Net Income of Rural Households is slightly mo ...

1960 Establishments In China
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Dong Fang Hong I
''Dong Fang Hong 1'' (), in the western world also known as China 1 or PRC 1, was the first space satellite of the People's Republic of China (PRC), launched successfully on 24 April 1970 as part of the PRC's Dongfanghong space satellite program. It was a part of the "Two Bombs, One Satellite" program. At , it was heavier than the first satellites of other countries. The satellite carried a radio transmitter which broadcast the ''de facto'' national anthem of the same name. The broadcast lasted for 20 days while in orbit. It was developed under the direction of Qian Xuesen, dean of the China Academy of Space Technology (CAST). At the time, a total of five identical satellites were created. The first satellite launched successfully. The academy formulated a "Three-Satellite Plan" consisting of ''Dongfanghong 1'', re-entry satellites, and geosynchronous orbit communications satellites. Sun Jiadong was responsible for the ''Dongfanghong 1'' technology. In 1967, Dang Hongxin chos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long March 1
The Long March 1 (长征一号), also known as the Changzheng-1 (CZ-1), was the first member of China's Long March rocket family. Like the U.S.'s and the Soviet Union's first rockets, it was based on a class of ballistic missiles, namely the DF-4 class. History Development started in January 1965 as the Seventh Ministry of Machinery Industry issued a design task. The two stage liquid fueled DF-4 was modified by adding a third stage in order to make it to the desired orbit. Long March 1's second flight launched China's first satellite Dong Fang Hong 1 to space on 24 April 1970. The rocket was operational during 1970–1971. Wang Xiji was the chief designer of the rocket.

Mao Zedong
Mao Zedong pronounced ; also romanised traditionally as Mao Tse-tung. (26 December 1893 – 9 September 1976), also known as Chairman Mao, was a Chinese communist revolutionary who was the founder of the People's Republic of China (PRC), which he led as the chairman of the Chinese Communist Party from the establishment of the PRC in 1949 until his death in 1976. Ideologically a Marxist–Leninist, his theories, military strategies, and political policies are collectively known as Maoism. Mao was the son of a prosperous peasant in Shaoshan, Hunan. He supported Chinese nationalism and had an anti-imperialist outlook early in his life, and was particularly influenced by the events of the Xinhai Revolution of 1911 and May Fourth Movement of 1919. He later adopted Marxism–Leninism while working at Peking University as a librarian and became a founding member of the Chinese Communist Party (CCP), leading the Autumn Harvest Uprising in 1927.

Bicycle Pump
A bicycle pump is a type of positive-displacement air pump specifically designed for inflating bicycle tires. It has a connection or adapter for use with one or both of the two most common types of valves used on bicycles, Schrader or Presta. A third type of valve called the Dunlop (or Woods) valve exists, but tubes with these valves can be filled using a Presta pump. Several basic types are available: * Floor pumps * Frame-mounted * Compact or mini * Foot-operated * Double-action * Blast or tubeless In its most basic form, a bicycle pump functions via a hand-operated piston. During up-stroke, this piston draws air through a one-way valve into the pump from outside. During down-stroke, the piston then displaces air from the pump into the bicycle tire. Most floor pumps, also commonly called track pumps, have a built-in pressure gauge to indicate tire pressure. Electrically-operated pumps intended to inflate car tires (as available in most service stations) can in prin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Signals
Hand signals are given by cyclists and some motorists to indicate their intentions to other traffic. Under the Vienna Convention on Traffic, bicycles are considered 'vehicles' and cyclists are considered 'drivers', a naming convention reflected in most traffic codes. In some countries such as the Czech Republic,The law of the Czech Republic361/2000 Sb. § 30 Canada, and the United States, hand signals apply not only to cyclists, but also to any vehicle whose signal lights are missing or damaged. This rule also applies to drivers of small motorized vehicles such as mopeds and motorcycles. As in automobiles, cyclists use three primary signals: left turn/overtaking, right turn, and stopping/braking. Left turn In right-hand traffic countries, the left turn hand signal is also used to indicate overtaking to the left. ; All countries : To signal a left turn, the driver horizontally extends their left arm outwards. ; South Africa : The driver extends his/her right arm with the ...

Ballistics
Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance. A ballistic body is a free-moving body with momentum which can be subject to forces such as the forces exerted by pressurized gases from a gun barrel or a propelling nozzle, normal force by rifling, and gravity and air drag during flight. A ballistic missile is a missile that is guided only during the relatively brief initial phase of powered flight and the trajectory is subsequently governed by the laws of classical mechanics; in contrast to (for example) a cruise missile which is aerodynamically guided in powered flight like a fixed-wing aircraft. History and prehistory The earliest known ballistic projectiles were stones and spears, and the throwing stick. The oldes ...
