Boundary Stones (District Of Columbia)
The boundary markers of the original District of Columbia are the 40 milestones that marked the four lines forming the boundaries between the states of Maryland and Virginia and the square of 100 square miles (259 km2) of federal territory that became the District of Columbia in 1801 (see: Founding of the District of Columbia). Working under the supervision of three commissioners that President George Washington had appointed in 1790 in accordance with the federal Residence Act, a surveying team led by Major Andrew Ellicott placed these markers in 1791 and 1792. Among Ellicott's assistants were his brothers Joseph and Benjamin Ellicott, Isaac Roberdeau, George Fenwick, Isaac Briggs and an African American astronomer, Benjamin Banneker. Today, 36 of the original marker stones survive as the oldest federally placed monuments in the United States. Thirteen of these markers are now within Virginia due to the return of the portion of the District south and west of the Poto ...

Columbia (name)
Columbia (; ), also known as Lady Columbia or Miss Columbia, is a female national personification of the United States. It was also a historical name applied to the Americas and to the New World. The association has given rise to the names of many American places, objects, institutions and companies, including the Washington, D.C., District of Columbia; Columbia, South Carolina; Columbia University; "Hail, Columbia"; ''Columbia Rediviva''; and the Columbia River. Images of the Statue of Liberty (''Liberty Enlightening the World'', erected in 1886) largely displaced anthropomorphism, personified Columbia as the female symbol of the United States by around 1920, and Lady Liberty was seen as both an aspect of Columbia and a rendition of the Liberty (personification), Goddess of Liberty.

Cartesian Coordinate System
In geometry, a Cartesian coordinate system (, ) in a plane (geometry), plane is a coordinate system that specifies each point (geometry), point uniquely by a pair of real numbers called ''coordinates'', which are the positive and negative numbers, signed distances to the point from two fixed perpendicular oriented lines, called ''coordinate lines'', ''coordinate axes'' or just ''axes'' (plural of ''axis'') of the system. The point where the axes meet is called the ''Origin (mathematics), origin'' and has as coordinates. The axes direction (geometry), directions represent an orthogonal basis. The combination of origin and basis forms a coordinate frame called the Cartesian frame. Similarly, the position of any point in three-dimensional space can be specified by three ''Cartesian coordinates'', which are the signed distances from the point to three mutually perpendicular planes. More generally, Cartesian coordinates specify the point in an -dimensional Euclidean space for any di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

District Of Columbia Retrocession
District of Columbia retrocession is the act of returning some or all of the land that had been ceded to the federal government of the United States for the purpose of creating its federal district for the new national capital, which was moved from Philadelphia to what was then called the City of Washington in 1800. The land was originally ceded to the federal government by Virginia and Maryland in 1790. After moving through various stages of federal and state approval, the Virginia portion was returned in March 1847. The District of Columbia's creation was the result of the District clause of the United States Constitution, but it has remained controversial and is opposed by some residents and those outside the District ever since. In the 1790 Residence Act the District originally consisted of of land, which was ceded to it by Maryland and Virginia, and it straddled the Potomac River. The 1801 Organic Act placed the areas under the control of the United States Congress and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
