William Harkness
William Harkness (December 17, 1837 – February 28, 1903) was an astronomer. He was born at Ecclefechan, Scotland, a son of James (1803–78) and Jane (née Wield) Harkness. His father was a pastor and moved the family to the United States. Harkness served in the military, traveled extensively, and headed research missions developing techniques and equipment for astronomical study. Harkness died at his home in Jersey City on February 28, 1903, at the age of 65. Biography Raised in Fishkill Landing, New York, Harkness was educated at Lafayette College (September 1854 – January 1856), graduated from the University of Rochester (1858) where he was a brother of Delta Kappa Epsilon, and then studied medicine in New York City.

Ecclefechan
Ecclefechan (Scottish Gaelic: ''Eaglais Fheichein'') is a village located in Dumfries and Galloway in the south of Scotland. The village is famous for being the birthplace of Thomas Carlyle. Ecclefechan lies in the valley of the Mein Water, a tributary of the River Annan, south of Lockerbie, north of Annan and northwest of the English border. The A74(M) motorway runs immediately north of the village and Junction 19 is just northwest of the village. The High Street of the village has a burn which runs through a culvert below it. This culvert was constructed in 1875 by Dr George Arnott at his own expense. Etymology The name ''Ecclefechan'' was recorded as ''Egilfeichane'' in 1507, and is of Brittonic origin. The first element is ''eglẹ:s'', meaning "a church" (cf. Welsh ''eglwys''). The second element is the equivalent of Welsh fe''chan'', meaning "little". Comparable Welsh toponyms include Eglwysfach and Llanfechan. A lesser likelihood is that the name commemorate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hobart
Hobart ( ) is the capital and most populous city of the island state of Tasmania, Australia. Located in Tasmania's south-east on the estuary of the River Derwent, it is the southernmost capital city in Australia. Despite containing nearly half of Tasmania's population, Hobart is the least-populated Australian state capital city, and second-smallest by population and area after Darwin if territories are taken into account. Material was copied from this source, which is available under Creative Commons Attribution 4.0 International License Its skyline is dominated by the kunanyi / Mount Wellington, and its harbour forms the second-deepest natural port in the world, with much of the city's waterfront consisting of reclaimed land. The metropolitan area is often referred to as Greater Hobart, to differentiate it from the City of Hobart, one of the seven local government areas that cover the city. It has a mild maritime climate. The city lies on country which was known by the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Of Venus
A transit of Venus takes place when Venus passes directly between the Sun and the Earth (or any other superior planet), becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus is visible as a small black circle moving across the face of the Sun. Transits of Venus reoccur periodically. A pair of transits takes place eight years apart in December (Gregorian calendar) followed by a gap of 121.5 years, before another pair occurs eight years apart in June, followed by another gap, of 105.5 years. The dates advance by about two days per 243-year cycle. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities. The last pairs of transits occurred on 8 June 2004 and 5–6 June 2012. The next pair of transits will occur on 10–11 December 2117 and 8 December 2125. Transits of Venus were in the past used to determine the size of the Solar System. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celestial Sphere
In astronomy and navigation, the celestial sphere is an abstract sphere that has an arbitrarily large radius and is concentric to Earth. All objects in the sky can be conceived as being projected upon the inner surface of the celestial sphere, which may be centered on Earth or the observer. If centered on the observer, half of the sphere would resemble a hemispherical screen over the observing location. The celestial sphere is a conceptual tool used in spherical astronomy to specify the position of an object in the sky without consideration of its linear distance from the observer. The celestial equator divides the celestial sphere into northern and southern hemispheres. Description Because astronomical objects are at such remote distances, casual observation of the sky offers no information on their actual distances. All celestial objects seem equally far away, as if fixed onto the inside of a sphere with a large but unknown radius, which appears to rotate westwa ...

Eclipse
An eclipse is an astronomical event which occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a ''syzygy''. An eclipse is the result of either an '' occultation'' (completely hidden) or a ''transit'' (partially hidden). A "deep eclipse" (or "deep occultation") is when a small astronomical object is behind a bigger one. "What is a deep eclipse? The smaller star is behind the bigger star" The term ''eclipse'' is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the ...

United States Hydrographic Office
The United States Hydrographic Office (USHO) prepared and published maps, charts, and nautical books required in navigation. The office was established by an act of 21 June 1866 as part of the Bureau of Navigation, Department of the Navy. It was transferred to the Department of Defense on 10 August 1949. The office was abolished on 10 July 1962, replaced by the Naval Oceanographic Office. Objectives Before the hydrographic office was established in 1866, U.S. navigators were almost entirely dependent on British charts. A few private enterprises had prepared and published charts, but had not been able to do so profitably. The Hydrographic Office was established "for the improvement of the means for navigating safely the vessels of the Navy and of the mercantile marine, by providing, under the authority of the Secretary of the Navy, accurate and cheap nautical charts, sailing directions, navigators and manuals of instructions for the use of all vessels of the United States, and f ...

Monitor (warship)
A monitor is a relatively small warship that is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War. The original monitor was designed in 1861 by John Ericsson, who named it . Subsequent vessels of this type were accordingly classed as "monitors". They were designed for shallow waters and served as coastal ships. The term also encompassed more flexible breastwork monitors, and was sometimes used as a generic term for any turreted ship. In the early 20th century, the term was revived for shallow-draught armoured shore bombardment vessels, particularly those of the Royal Navy: the s carried guns firing heavier shells than any other warship ever has, seeing action (albeit briefly) against German targets during World War I. The ''Lord Clive'' vessels were scrapped in the 1920s. The term "monitor" also encompasses the strongest of riverine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ad Eundem Degree
An degree is an academic degree awarded by one university or college to an alumnus of another, in a process commonly known as incorporation. The recipient of the degree is often a faculty member at the institution which awards the degree, e.g. at the University of Cambridge, where incorporation is expressly limited to a person who "has been admitted to a University office or a Headship or a Fellowship (other than an Honorary Fellowship) of a College, or holds a post in the University Press ... or is a Head-elect or designate of a College".Ordinances of the University of Cambridge, Chapter IISection 8. Incorporation An degree is not an earned degree. History In the later Middle Ages it was common, when a graduate from one university moved into the neighborhood of another, for the new university to admit the graduate as a courtesy, "at the same degree" (in Latin, ). Thus if someone was a Bachelor of Arts in the university that they had attended, they would likewise be a bachel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Fort Stevens
The Battle of Fort Stevens was an American Civil War battle fought July 11–12, 1864, in Washington County, D.C. in present-day Northwest Washington, D.C., during the Valley campaigns of 1864 between forces under Confederate Lieutenant General Jubal Early and Union Major General Alexander McDowell McCook. Early's attack, less than from the White House, caused consternation in the U.S. government, but reinforcements under Maj. Gen. Horatio G. Wright and the strong defenses of Fort Stevens minimized the threat. Early withdrew after two days of skirmishing after attempting no serious assaults. Then U.S. President Abraham Lincoln personally observed the battle's fighting. Background In June 1864, Lt. Gen. Jubal Early was dispatched by Gen. Robert E. Lee with the Second Corps of the Army of Northern Virginia from the Confederate lines around the Confederate capital of Richmond, Virginia, with orders to clear the Shenandoah Valley of Federals and, if practical, to invad ...

Lieutenant Commander (United States)
Lieutenant commander (LCDR) is a senior officer rank in the United States Navy, the United States Coast Guard, the United States Public Health Service Commissioned Corps, and the National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps), with the pay grade of O-4 and NATO rank code OF-3. Lieutenant commander ranks above lieutenant and below commander. The rank is also used in the United States Maritime Service . The rank is equivalent to a major in the United States Army, United States Air Force, United States Marine Corps, and United States Space Force. When introducing a lieutenant commander, their full rank should always be used; however, in general conversation they are usually called "commander" even though they are not "full" commanders (which is one rank higher). Simply "lieutenant" is never used because it is one rank lower. Promotion to lieutenant commander in the U.S. Navy is governed by United States Department of Defense policies deri ...
