1964 New York World's Fair
The 1964–1965 New York World's Fair was a world's fair that held over 140 pavilions and 110 restaurants, representing 80 nations (hosted by 37), 24 US states, and over 45 corporations with the goal and the final result of building exhibits or attractions at Flushing Meadows–Corona Park in Queens, New York City. The immense fair covered on half the park, with numerous pools or fountains, and an amusement park with rides near the lake. However, the fair did not receive official support or approval from the Bureau of International Expositions (BIE). Hailing itself as a "universal and international" exposition, the fair's theme was "Peace Through Understanding", dedicated to "Man's Achievement on a Shrinking Globe in an Expanding Universe". American companies dominated the exposition as exhibitors. The theme was symbolized by a 12-story-high, stainless-steel model of the Earth called the Unisphere, built on the foundation of the Perisphere from the 1939 World's Fair.Gordon, Joh ...

Unisphere
The Unisphere is a spherical stainless steel representation of the Earth in Flushing Meadows–Corona Park in the New York City borough of Queens. The globe was designed by Gilmore D. Clarke as part of his plan for the 1964 New York World's Fair. Commissioned to celebrate the beginning of the space age, the Unisphere was conceived and constructed as the theme symbol of the World's Fair. The theme of the World's Fair was "Peace Through Understanding", and the Unisphere represented the theme of global interdependence, being dedicated to "Man's Achievements on a Shrinking Globe in an Expanding Universe". The Unisphere measures high and in diameter. It sits atop a tripod base with over 500 steel pieces representing the continents, as well as three steel rings representing the first artificial satellites orbiting Earth. Around the Unisphere is a reflecting pool measuring in diameter. The base is surrounded by 48 pairs of fountainheads, which were intended to conceal the tripod ...

Perisphere
The Trylon and Perisphere were two monumental modernistic structures designed by architects Wallace Harrison and J. Andre Fouilhoux that were together known as the Theme Center of the 1939 New York World's Fair. The Perisphere was a tremendous sphere, in diameter, connected to the spire-shaped Trylon by what was at the time the world's longest escalator. The Perisphere housed a diorama by Henry Dreyfuss called ''Democracity'' which, in keeping with the fair's theme "The World of Tomorrow", depicted a utopian city-of-the-future. The interior display was viewed from above on a moving sidewalk, while a multi-image slide presentation was projected on the dome of the sphere. After exiting the Perisphere, visitors descended to ground level on the third element of the Theme Center, the Helicline, a spiral ramp that partially encircled the Perisphere. The name "Perisphere" was coined using the Greek prefix ''peri-'', meaning "all around", "about", or "enclosing". The name "Trylon" was ...

Flushing River
The Flushing River, also known as Flushing Creek, is a waterway that flows northward through the borough of Queens in New York City, mostly within Flushing Meadows–Corona Park, emptying into the Flushing Bay and the East River. The river runs through a valley that may have been a larger riverbed before the last Ice Age, and it divides Queens into western and eastern halves. Until the 20th century, the Flushing Creek was fed by three tributaries: Mill Creek and Kissena Creek on the eastern bank, and Horse Brook on the western bank. In the 18th and 19th centuries, it divided the towns of Flushing on its right bank, to the east, and Newtown (now part of Corona) on its left bank, to the west. Several bridges were built across the Flushing River in the 19th and 20th centuries. Prior to the 1939 New York World's Fair, the southern portion of the river was expanded into the Meadow and Willow Lakes. A part of the Flushing River was buried prior to the 1964 New York World's Fair. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borough (New York City)
New York City is composed of five boroughs: The Bronx, Brooklyn, Manhattan, Queens, and Staten Island. Each borough is coextensive with a respective county of New York State, making New York City the largest U.S. municipality situated in multiple counties. The boroughs of Queens and the Bronx are also Queens County and Bronx County. The other three counties are named differently from their boroughs: Manhattan is New York County, Brooklyn is Kings County, and Staten Island is Richmond County. All five boroughs came into existence with the creation of modern New York City in 1898, when New York County (including The Bronx), Kings County, part of Queens County, and Richmond County were consolidated within one municipal government under a new city charter. All former municipalities within the newly consolidated city were eliminated. New York City was originally confined to Manhattan Island and the smaller surrounding islands that formed New York County. As the city grew northw ...

Telephone Modem
A modulator-demodulator or modem is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio. Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 bit/s for asynchronous dial connections, 4,800 bit/s for synchron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Punch Card
A punched card (also punch card or punched-card) is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery. Punched cards were widely used through much of the 20th century in the data processing industry, where specialized and increasingly complex unit record machines, organized into semiautomatic data processing systems, used punched cards for data input, output, and storage. The IBM 12-row/80-column punched card format came to dominate the industry. Many early digital computers used punched cards as the primary medium for input of both computer programs and data. While punched cards are now obsolete as a storage medium, as of 2012, some voting machines still used punched cards to record votes. They also had a significant cultural impact. History The idea of control and data storage via punched holes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleprinter
A teleprinter (teletypewriter, teletype or TTY) is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations. Initially they were used in telegraphy, which developed in the late 1830s and 1840s as the first use of electrical engineering, though teleprinters were not used for telegraphy until 1887 at the earliest. The machines were adapted to provide a user interface to early mainframe computers and minicomputers, sending typed data to the computer and printing the response. Some models could also be used to create punched tape for data storage (either from typed input or from data received from a remote source) and to read back such tape for local printing or transmission. Teleprinters could use a variety of different communication media. These included a simple pair of wires; dedicated non-switched telephone circuits (leased lines); switched network ...

Computer Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. The teletype was an example of an early-day hard-copy terminal and predated the use of a computer screen by decades. Early terminals were inexpensive devices but very slow compared to punched cards or paper tape for input, yet as the technology improved and video displays were introduced, terminals pushed these older forms of interaction from the industry. A related development was time-sharing systems, which evolved in parallel and made up for any inefficiencies in the user's typing ability with the ability to support multiple users on the same machine, each at their own terminal or terminals. The function of a terminal is typically confined to transcription and input of data; a device with significant local, programmable data-processing capability may be called a "smart terminal" or fat client.

Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainframe design is characterized less b ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...
