Elliptic Dome
An elliptical dome, or an ''oval dome'', is a dome whose bottom cross-section takes the form of an ellipse. Technically, an ''ellipsoidal dome'' has a circular cross-section, so is not quite the same. While the cupola can take different geometries, when the ceiling's cross-section takes the form of an ellipse, and due to the reflecting properties of an ellipse, any two persons standing at a focus of the floor's ellipse can have one whisper, and the other hears; this is a whispering gallery. The largest elliptical dome in the world is at the Sanctuary of Vicoforte in Vicoforte, Italy. In architecture Elliptical domes have many applications in architecture; and are useful in covering rectangular spaces. The oblate, or horizontal elliptical dome is useful when there is a need to limit height of the space that would result from a spherical dome. As the mathematical description of an elliptical dome is more complex than that of spherical dome, design care is needed. In a geo ...

Spherical Dome
In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane. If the plane passes through the center of the sphere (forming a great circle), so that the height of the cap is equal to the radius of the sphere, the spherical cap is called a ''hemisphere''. Volume and surface area The volume of the spherical cap and the area of the curved surface may be calculated using combinations of * The radius r of the sphere * The radius a of the base of the cap * The height h of the cap * The polar angle \theta between the rays from the center of the sphere to the apex of the cap (the pole) and the edge of the disk forming the base of the cap. These variables are inter-related through the formulas a = r \sin \theta, h = r ( 1 - \cos \theta ), 2hr = a^2 + h^2, and 2 h a = (a^2 + h^2)\sin \theta. If \phi denotes the latitude in geographic coordinates, then \theta+\phi = \ ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Church Of Saint Roch, Žižkov
The Church of Saint Roch, located on Olšany Square (Czech: ''Olšanské náměstí''), is the oldest church in present-day Žižkov, a cadastral district of Prague, Czech Republic. The Baroque structure was built between 1680 and 1682 by Jan Hainric, probably according to plans by the renowned French architect Jean Baptiste Mathey. History The stimulus for the church's construction was the plague epidemic which broke out in Prague in early 1680. So many citizens of Prague were killed, that new cemeteries needed to be established outside the city walls. Plague cemeteries were laid out in Olšany for the Old Town, New Town, and Jewish Quarter. The Old Town City Council also decided to build a pestilence chapel on its newly established burial ground. It was dedicated to St. Roch, a patron saint of plague victims. The Church of Saint Roch continued to function as a cemetery church, even after the Olšany Cemetery began to accept regular burials among the plague victims. In 1839, ...

Basilica Of St
In Ancient Roman architecture, a basilica (Greek Basiliké) was a large public building with multiple functions that was typically built alongside the town's Forum (Roman), forum. The basilica was in the Latin West equivalent to a stoa in the Greek East. The building gave its name to the ''basilica'' architectural form. Originally, a basilica was an ancient Roman architecture, ancient Roman public building, where courts were held, as well as serving other official and public functions. Basilicas are typically rectangular buildings with a central nave flanked by two or more longitudinal aisles, with the roof at two levels, being higher in the centre over the nave to admit a clerestory and lower over the side-aisles. An apse at one end, or less frequently at both ends or on the side, usually contained the raised Tribune (architecture), tribunal occupied by the Roman magistrates. The basilica was centrally located in every Roman town, usually adjacent to the forum and often opp ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mosques
A mosque ( ), also called a masjid ( ), is a place of worship for Muslims. The term usually refers to a covered building, but can be any place where Islamic prayers are performed; such as an outdoor courtyard. Originally, mosques were simple places of prayer for the early Muslims, and may have been open spaces rather than elaborate buildings. In the first stage of Islamic architecture (650–750 CE), early mosques comprised open and closed covered spaces enclosed by walls, often with minarets, from which the Islamic call to prayer was issued on a daily basis. It is typical of mosque buildings to have a special ornamental niche (a ''mihrab'') set into the wall in the direction of the city of Mecca (the ''qibla''), which Muslims must face during prayer, as well as a facility for ritual cleansing (''wudu''). The pulpit ('' minbar''), from which public sermons (''khutbah'') are delivered on the event of Friday prayer, was, in earlier times, characteristic of the central city mosque ...

Pentagons
In geometry, a pentagon () is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting ''regular pentagon'' (or ''star pentagon'') is called a pentagram. Regular pentagons A ''regular pentagon'' has Schläfli symbol and interior angles of 108°. A ''regular pentagon'' has five lines of reflectional symmetry, and rotational symmetry of order 5 (through 72°, 144°, 216° and 288°). The diagonals of a convex regular pentagon are in the golden ratio to its sides. Given its side length t, its height H (distance from one side to the opposite vertex), width W (distance between two farthest separated points, which equals the diagonal length D) and circumradius R are given by: :\begin H &= \frac~t \approx 1.539~t, \\ W= D &= \frac~t\approx 1.618~t, \\ W &= \sqrt \cdot H\approx 1.051~H, \\ R &= \sqrt t\approx 0.8507~t, \\ D &= R\ = 2R\cos 18^\circ = ...

Hexagons
In geometry, a hexagon (from Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°. Regular hexagon A regular hexagon is defined as a hexagon that is both equilateral and equiangular. In other words, a hexagon is said to be regular if the edges are all equal in length, and each of its internal angle is equal to 120°. The Schläfli symbol denotes this polygon as \ . However, the regular hexagon can also be considered as the cutting off the vertices of an equilateral triangle, which can also be denoted as \mathrm\ . A regular hexagon is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle). The common length of the sides equals the radius of the circumscribed circle or circumcircle, which equals \tfrac times the apothem (radius of the inscribed circle).
