Satellite
In 1957 the Soviet Union launched the world's first artificial satellite, Sputnik 1. Since then, about 6,600 satellites from more than 40 countries have been launched. According to a 2013 estimate, 3,600 remained in orbit. Of those, about 1,000 were operational; while the rest have lived out their useful lives and become space debris. Approximately 500 operational satellites are in low - Earth orbit, 50 are in medium - Earth orbit (at 20,000 km), and the rest are in geostationary orbit (at 36,000 km). A few large satellites have been launched in parts and assembled in orbit. Over a dozen space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, a few asteroids, a comet and the Sun.
Soviet Union
The Soviet Union suffered greatly in the war, losing around 27 million people. Approximately 2.8 million Soviet POWs died of starvation, mistreatment, or executions in just eight months of 1941 -- 42. During the war, the Soviet Union together with the United States, the United Kingdom and China were considered as the Big Four of Allied powers in World War II and later became the Four Policemen which was the foundation of the United Nations Security Council. It emerged as a superpower in the post-war period. Once denied diplomatic recognition by the Western world, the Soviet Union had official relations with practically every nation by the late 1940s. A member of the United Nations at its foundation in 1945, the Soviet Union became one of the five permanent members of the United Nations Security Council, which gave it the right to veto any of its resolutions.
Satellite
Following pressure by the American Rocket Society, the National Science Foundation, and the International Geophysical Year, military interest picked up and in early 1955 the Army and Navy were working on Project Orbiter, two competing programs: the army's which involved using a Jupiter C rocket, and the civilian / Navy Vanguard Rocket, to launch a satellite. At first, they failed: initial preference was given to the Vanguard program, whose first attempt at orbiting a satellite resulted in the explosion of the launch vehicle on national television. But finally, three months after Sputnik 2, the project succeeded; Explorer 1 became the United States' first artificial satellite on 31 January 1958.
List of presidents of India
Seven presidents have been members of a political party before being elected. Six of these were active party members of the Indian National Congress. The Janata Party has had one member, Neelam Sanjiva Reddy, who later became president, he was born in Anantapur District (now Andhra Pradesh). Two presidents, Zakir Husain and Fakhruddin Ali Ahmed, have died in office. Their vice-presidents functioned as acting president until a new president was elected. Following Zakir Husain's death, two acting presidents held office until the new president, V.V. Giri, was elected. Varahagiri Venkata Giri himself, Zakir Husain's vice president, was the first acting president. When Giri resigned to take part in the presidential elections, he was succeeded by Mohammad Hidayatullah as acting president. The 12th president, Pratibha Patil, is the first woman to serve as President of India, elected in 2007.
Refrigerator
The first cooling systems for food involved using ice. Artificial refrigeration began in the mid-1750s, and developed in the early 1800s. In 1834, the first working vapor - compression refrigeration system was built. The first commercial ice - making machine was invented in 1854. In 1913, refrigerators for home use were invented. In 1923 Frigidaire introduced the first self - contained unit. The introduction of Freon in the 1920s expanded the refrigerator market during the 1930s. Home freezers as separate compartments (larger than necessary just for ice cubes) were introduced in 1940. Frozen foods, previously a luxury item, became commonplace.
Dynatron oscillator
In electronics, the dynatron oscillator, invented in 1918 by Albert Hull at General Electric, is an obsolete vacuum tube electronic oscillator circuit which uses a negative resistance characteristic in early tetrode vacuum tubes, caused by a process called secondary emission. It was the first negative resistance vacuum tube oscillator. The dynatron oscillator circuit was used to a limited extent as beat frequency oscillators (BFOs), and local oscillators in vacuum tube radio receivers as well as in scientific and test equipment from the 1920s to the 1940s but became obsolete around World War 2 due to the variability of secondary emission in tubes.
History of programming languages
In 1954, language FORTRAN was invented at IBM by a team led by John Backus; it was the first widely used high level general purpose programming language to have a functional implementation, as opposed to just a design on paper. It is still a popular language for high - performance computing and is used for programs that benchmark and rank the world's fastest supercomputers.
Space Race
The Soviet success caused public controversy in the United States, and Eisenhower ordered the civilian rocket and satellite project, Vanguard, to move up its timetable and launch its satellite much sooner than originally planned. The December 6, 1957 Project Vanguard launch failure occurred at Cape Canaveral Air Force Station in Florida, broadcast live in front of a US television audience. It was a monumental failure, exploding a few seconds after launch, and it became an international joke. The satellite appeared in newspapers under the names Flopnik, Stayputnik, Kaputnik, and Dudnik. In the United Nations, the Russian delegate offered the U.S. representative aid "under the Soviet program of technical assistance to backwards nations." Only in the wake of this very public failure did von Braun's Redstone team get the go-ahead to launch their Jupiter-C rocket as soon as they could. In Britain, the USA's Western Cold War ally, the reaction was mixed: some members of the population celebrated the fact that the Soviets had reached space first, while others feared the destructive potential that military uses of spacecraft might bring.
Association of Scouts of Azerbaijan
The Association of Scouts of Azerbaijan (), (ASA) the national Scouting organization of Azerbaijan, was founded in 1997, and became the 150th member of the World Organization of the Scout Movement on 20 August 2000. In 2017 it was admitted as a full member in the World Association of Girl Guides and Girl Scouts. The coeducational association has 1,748 members as of 2012, about 35 % are girls.
Hellenistic period
Hellenistic Geometers such as Archimedes (c. 287 – 212 BC), Apollonius of Perga (c. 262 – c. 190 BC), and Euclid (c. 325 – 265 BC), whose Elements became the most important textbook in mathematics until the 19th century, built upon the work of the Hellenic era Pythagoreans. Euclid developed proofs for the Pythagorean Theorem, for the infinitude of primes, and worked on the ﬁve Platonic solids. Eratosthenes used his knowledge of geometry to measure the circumference of the Earth. His calculation was remarkably accurate. He was also the first to calculate the tilt of the Earth's axis (again with remarkable accuracy). Additionally, he may have accurately calculated the distance from the Earth to the Sun and invented the leap day. Known as the "Father of Geography ", Eratosthenes also created the first map of the world incorporating parallels and meridians, based on the available geographical knowledge of the era.
Israel
The Israeli Space Agency coordinates all Israeli space research programs with scientific and commercial goals. In 2012 Israel was ranked ninth in the world by the Futron's Space Competitiveness Index. Israel is one of only seven countries that both build their own satellites and launch their own launchers. The Shavit is a space launch vehicle produced by Israel to launch small satellites into low earth orbit. It was first launched in 1988, making Israel the eighth nation to have a space launch capability. Shavit rockets are launched from the spaceport at the Palmachim Airbase by the Israeli Space Agency. Since 1988 Israel Aerospace Industries have indigenously designed and built at least 13 commercial, research and spy satellites. Some of Israel's satellites are ranked among the world's most advanced space systems. In 2003, Ilan Ramon became Israel's first astronaut, serving as payload specialist of STS-107, the fatal mission of the Space Shuttle Columbia.
Mel Pinto
Mel Pinto (born September 9, 1923, Tangiers, Morocco), became one of the first importers of European racing bikes into the United States in 1958 when he opened Mel Pinto Imports in northern Virginia and began selling Gitane bicycles on consignment. Later, Pinto was the first to import Shimano’s Dura-Ace components into the U.S. In 1960, Pinto became a founding member of the Federation of Washington Area Bicycle Clubs, now known as the National Capital Velo Club, and in 1963 revived the moribund National Capital Open bicycle race in Washington, D.C., reestablishing it as an annual event on The Ellipse until the race’s demise in 1988.
Space Race
In 1953, Korolev was given the go-ahead to develop the R-7 Semyorka rocket, which represented a major advance from the German design. Although some of its components (notably boosters) still resembled the German G-4, the new rocket incorporated staged design, a completely new control system, and a new fuel. It was successfully tested on August 21, 1957 and became the world's first fully operational ICBM the following month. It would later be used to launch the first satellite into space, and derivatives would launch all piloted Soviet spacecraft.
BeiDou
The second generation of the system, officially called the BeiDou Navigation Satellite System (BDS) and also known as COMPASS or BeiDou-2, will be a global satellite navigation system consisting of 35 satellites, and is under construction as of January 2015[update]. It became operational in China in December 2011, with 10 satellites in use, and began offering services to customers in the Asia-Pacific region in December 2012. It is planned to begin serving global customers upon its completion in 2020.
Han dynasty
Evidence of Han-era mechanical engineering comes largely from the choice observational writings of sometimes disinterested Confucian scholars. Professional artisan-engineers (jiang 匠) did not leave behind detailed records of their work. Han scholars, who often had little or no expertise in mechanical engineering, sometimes provided insufficient information on the various technologies they described. Nevertheless, some Han literary sources provide crucial information. For example, in 15 BC the philosopher Yang Xiong described the invention of the belt drive for a quilling machine, which was of great importance to early textile manufacturing. The inventions of the artisan-engineer Ding Huan (丁緩) are mentioned in the Miscellaneous Notes on the Western Capital. Around 180 AD, Ding created a manually operated rotary fan used for air conditioning within palace buildings. Ding also used gimbals as pivotal supports for one of his incense burners and invented the world's first known zoetrope lamp.
Andover Earth Station
Andover Earth Station was one of the first satellite earth stations, located at Andover in the US state of Maine. It was built by AT&T in 1961 to communicate with the Telstar 1 satellite, the first direct relay communications satellite. It provided the first experimental satellite telephone and television service between North America and Europe. It was also used with the Relay satellite. The station was dismantled in the 1990s.
Intellectual property
A patent is a form of right granted by the government to an inventor, giving the owner the right to exclude others from making, using, selling, offering to sell, and importing an invention for a limited period of time, in exchange for the public disclosure of the invention. An invention is a solution to a specific technological problem, which may be a product or a process and generally has to fulfil three main requirements: it has to be new, not obvious and there needs to be an industrial applicability.:17
President of the United Nations General Assembly
Miroslav Lajčák of Slovakia has been elected as the United Nations General Assembly President of its 72nd session beginning in September 2017.
HPV vaccine
The first HPV vaccine became available in 2006. As of 2017, 71 countries include it in their routine vaccinations, at least for girls. They are on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is about US $47 a dose as of 2014. In the United States it costs more than US $200. Vaccination may be cost effective in the developing world.
Dwight D. Eisenhower
The contacts gained through university and American Assembly fund-raising activities would later become important supporters in Eisenhower's bid for the Republican party nomination and the presidency. Meanwhile, Columbia University's liberal faculty members became disenchanted with the university president's ties to oilmen and businessmen, including Leonard McCollum, the president of Continental Oil; Frank Abrams, the chairman of Standard Oil of New Jersey; Bob Kleberg, the president of the King Ranch; H. J. Porter, a Texas oil executive; Bob Woodruff, the president of the Coca-Cola Corporation; and Clarence Francis, the chairman of General Foods.
