William Brydone Jack Observatory
The William Brydone Jack Observatory is a small astronomical observatory on the campus of the University of New Brunswick in Fredericton, New Brunswick. Constructed in 1851, it was the first astronomical observatory built in British North America. The observatory was designated a National Historic Site of Canada in 1954. Beginnings In 1840 William Brydone Jack became professor of Mathematics and Natural Philosophy at King's College, which later became the University of New Brunswick. In 1847 he and James Robb, the college's professor of Chemistry and Natural History, wrote to the College Council requesting money to purchase scientific equipment. An enthusiastic astronomer himself and supported by New Brunswick Lieutenant Governor Sir Edmund Walker Head, Brydone Jack persuaded the council to grant funds for the purchase of a telescope and other astronomy equipment. The 7.5 foot mahogany and brass achromatic telescope with an equatorial mount was built by the German manufa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Equatorial Mount
An equatorial mount is a mount for instruments that compensates for Earth's rotation by having one rotational axis, called ''polar axis'', parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescope mount, telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any celestial object with diurnal motion by driving one axis at a constant speed. Such an arrangement is called a ''sidereal drive'' or ''clock drive''. Equatorial mounts achieve this by aligning their rotational axis with the Earth, a process known as ''polar alignment''. Astronomical telescope mounts In astronomical telescope mounts, the equatorial axis (the ''right ascension'') is paired with a second perpendicular coordinate axis, axis of motion (known as the ''declination''). The equatorial axis of the mount is often equipped with a motorized "''clock drive''", that rotates that axis one revolution e ...

Astronomical Observatories In Canada
Astronomy is a natural science that studies astronomical object, celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Ch ...

List Of Astronomical Observatories
This is a partial list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Brunswickan
''The Brunswickan'' is the official student newspaper of the Fredericton, New Brunswick, Fredericton campus of the University of New Brunswick, New Brunswick, Canada. Founded in 1867, it has a circulation of 4,000 and issues are published on the first Wednesday each month, traditionally running 8 issues annually. Overview A founding member of the Canadian University Press, ''The Brunswickan'' remains one of the largest community newspapers in Atlantic Canada, and among the largest in Canada, well out-of-proportion to the size of its home campus. In January 2009, the paper switched from broadsheet to tabloid format in response to financial pressures, and in an effort to reduce its impact on the environment. ''The Brunswickan'' subsequently dropped its circulation from 10,000 to 6,000 issues per week later that month, and again to 5,000 in 2012. Circulation dropped again to 4,000 in September 2013. By the 2024-25 publishing term, print runs dropped to 200 copies per issue, undersc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gable
A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. The term gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it. Some types of roof do not have a gable (for example hip roofs do not). One common type of roof with gables, the 'gable roof', is named after its prominent gables. A parapet made of a series of curves (shaped gable, see also Dutch gable) or horizontal steps (crow-stepped gable) may hide the diagonal lines of the roof. Gable ends of more recent buildings are often treated in the same way as the Classic pediment form. But unlike Classical structures, which operate through post and lintel, trabeation, the gable ends of many buildings are actually bearing-wall structures. Gable style is also used in the design of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Cladding
There are four main techniques used today in the UK and mainland Europe for copper cladding a building: * seamed-Cladding (construction), cladding (typically 0.7 mm thick copper sheet on the facade): max 600 mm by 4000 mm 'seam centres'. * shingle-cladding (typically made from 0.7 mm thick copper sheet): max 600 mm by 4000 mm 'seam centres'. * slot-in wikt:panel, panels (typically made from 1.0 mm thick copper sheet): max 350 mm wide for 1.0 mm, by nominal 4 m length. * cassettes (typically made from 1.0 mm up to 1.5 mm thick copper sheet): largest-format cladding elements, more subframing is needed: can be 900 mm x nominal 4000 mm length. When selecting size of a cladding element, take wind-loadings into account, and also consider the standard sizes available of the sheet (or coil) pre-material, to minimise material wastage through off-cuts. This helps to reduce costs. The choice of which system to use depen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siding (construction)
Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable, more comfortable environment on the interior side. The siding material and style also can enhance or detract from the building's beauty. There is a wide and expanding variety of materials to side with, both natural and artificial, each with its own benefits and drawbacks. Masonry walls as such do not require siding, but any wall can be sided. Walls that are internally framed, whether with wood, or steel I-beams, however, must always be sided. Most siding consists of pieces of weather-resistant material that are smaller than the wall they cover, to allow for expansion and contraction of the materials due to moisture and temperature changes. There are various styles of joining the pieces, from board and batton, wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clapboard (architecture)
Clapboard (), also called bevel siding, lap siding, and weatherboard, with regional variation in the definition of those terms, is wooden siding of a building in the form of horizontal boards, often overlapping. ''Clapboard'', in modern American usage, is a word for long, thin boards used to cover walls and (formerly) roofs of buildings. Historically, it has also been called ''clawboard'' and ''cloboard''. In the United Kingdom, Australia and New Zealand, the term ''weatherboard'' is always used. An older meaning of "clapboard" is small split pieces of oak imported from Germany for use as barrel staves, and the name is a partial translation (from , "to fit") of Middle Dutch and related to German . Types Riven Clapboards were originally riven radially by hand producing triangular or "feather-edged" sections, attached thin side up and overlapped thick over thin to shed water.
