Allegheny Center (Pittsburgh)
Allegheny Center is a neighborhood on Pittsburgh's North Side. Its zip code is 15212, and it has representation on Pittsburgh City Council by both council members for District 6 (Downtown, North Shore) and District 1 (Northside). History In 1783, the Commonwealth of Pennsylvania established a 3000-acre tract of land north of where the Allegheny River merged with the Ohio River. John Redick created an initial town plan for Allegheny City- which featured 36 city blocks surrounded by a common grazing area - the following year. That initial 36-block area is today's Allegheny Center. It is still surrounded on three sides by the former grazing area, now a public park called Allegheny Commons. On either side of this park are the neighborhoods of Allegheny West and East Allegheny. Because Allegheny City was intended by the Pennsylvania Legislature to serve as the county seat of Allegheny County, the central blocks of Redick's 36-block plan were designed for public uses, includi ...

Educational Buildings In Pittsburgh
Education is a purposeful activity directed at achieving certain aims, such as transmitting knowledge or fostering skills and character traits. These aims may include the development of understanding, rationality, kindness, and honesty. Various researchers emphasize the role of critical thinking in order to distinguish education from indoctrination. Some theorists require that education results in an improvement of the student while others prefer a value-neutral definition of the term. In a slightly different sense, education may also refer, not to the process, but to the product of this process: the mental states and dispositions possessed by educated people. Education originated as the transmission of cultural heritage from one generation to the next. Today, educational goals increasingly encompass new ideas such as the liberation of learners, skills needed for modern society, empathy, and complex vocational skills. Types of education are commonly divided into formal, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Pittsburgh History And Landmarks Foundation Historic Landmarks
Pittsburgh History and Landmarks Foundation (PHLF) Historic Landmark plaque program was begun in 1968 in order to identify architecturally significant structures as well as significant pieces of Pittsburgh's local heritage throughout Allegheny County. Nominations are reviewed by the private non-profit foundation's Historic Plaque Designation Committee composed of trustees, architectural historians, and citizens. These designations are not to be confused with City of Pittsburgh historic designations. Beginning in 2010, the committee expanded its program to consider applications for historic status from counties surrounding Allegheny, extending its reach to a 250-mile radius from the city, as long as the site has a connection to the greater Pittsburgh region. Historic designation by the foundation does not protect the building from alteration or demolition. Structures awarded the designation typically have aluminum or bronze plaques affixed to their exterior that signify their status. ...

Miniature Railroad & Village
The Miniature Railroad & Village (MRRV) is a large and detailed model train layouts diorama of western Pennsylvania from 1880 to 1930. It is a long-running display currently located in the Carnegie Science Center in Pittsburgh, Pennsylvania, the MRRV has been a Pittsburgh tradition for over 50 years. History The exhibit was initiated by Charles Bowdish (1896–1988) of Brookville, Pennsylvania. Bowdish was a soldier during World War I. When doctors discovered a congenital heart problem, he was honorably discharged from service and sent home, where he began to build models of structures around Brookville, his hometown. Every Christmas, in his home on Creek Street (the house has since been demolished), the buildings were assembled in a display, complete with Lionel trains running through it. On Christmas Eve 1920, Charles hosted his brother's wedding and reception, and entertained the guests by running his train display. One of the guests, Alfred Truman, asked if he ...

Siderostat
A heliostat (from ''helios'', the Greek word for ''sun'', and ''stat'', as in stationary) is a device that includes a mirror, usually a plane mirror, which turns so as to keep reflecting sunlight toward a predetermined target, compensating for the sun's apparent motions in the sky. The target may be a physical object, distant from the heliostat, or a direction in space. To do this, the reflective surface of the mirror is kept perpendicular to the bisector of the angle between the directions of the sun and the target as seen from the mirror. In almost every case, the target is stationary relative to the heliostat, so the light is reflected in a fixed direction. According to contemporary sources the heliostata, as it was called at first, was invented by Willem 's Gravesande (1688–1742). Other contenders are Giovanni Alfonso Borelli (1608–1679) and Daniel Gabriel Fahrenheit (1686–1736). A Heliostat designed by George Johnstone Storey is in the Science Museum Group collect ...

Foucault Pendulum
The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. A long and heavy pendulum suspended from the high roof above a circular area was monitored over an extended time period, showing that the plane of oscillation rotated. The pendulum was introduced in 1851 and was the first experiment to give simple, direct evidence of the Earth's rotation. Foucault pendulums today are popular displays in science museums and universities. Original Foucault pendulum The first public exhibition of a Foucault pendulum took place in February 1851 in the Meridian of the Paris Observatory. A few weeks later, Foucault made his most famous pendulum when he suspended a brass-coated lead bob (physics), bob with a wire from the dome of the Panthéon, Paris. The proper period of the pendulum was approximately 2\pi\sqrt\approx 16.5 \,\mathrm. Because the latitude of its location was \ph ...

Classical Architecture
Classical architecture usually denotes architecture which is more or less consciously derived from the principles of Greek and Roman architecture of classical antiquity, or sometimes even more specifically, from the works of the Roman architect Vitruvius. Different styles of classical architecture have arguably existed since the Carolingian Renaissance, and prominently since the Italian Renaissance. Although classical styles of architecture can vary greatly, they can in general all be said to draw on a common "vocabulary" of decorative and constructive elements. In much of the Western world, different classical architectural styles have dominated the history of architecture from the Renaissance until the second world war, though it continues to inform many architects to this day. The term ''classical architecture'' also applies to any mode of architecture that has evolved to a highly refined state, such as classical Chinese architecture, or classical Mayan architecture.
