Martín Cortés De Albacar
Martín Cortés de Albacar (1510–1582) was a Spanish cosmographer.p131 Antonio Barrera-Osorio ''Experiencing nature: the Spanish American empire and the early scientific revolution;'' University of Texas Press, 2006 In 1551 he published the standard navigational textbook ''Arte de navegar'' (also known as ''Breve compendio'') Cortés was born in Bujaraloz, province of Zaragoza, Aragon. From 1530, in Cádiz, he taught cosmography and the art of navigation to pilots. ''Art of Navigation'' Cortés' book, ''Breve compendio,''...''Arte de navegar'' was promoted by Steven Borough who had it translated into English by Richard Eden and published in 1561 entitled ''The Art of Navigation.'' As such it became the first English manual of navigationAndrew Hadfield, ‘Eden, Richard (c.1520–1576)’, ''Oxford Dictionary of National Biography'', Oxford University Press, Sept 2004 and the primary text for European navigation throughout the early 17thC, enjoyed by such as Martin Frobisher ...

Magnetic Declination
Magnetic declination, or magnetic variation, is the angle on the horizontal plane between magnetic north (the direction the north end of a magnetized compass needle points, corresponding to the direction of the Earth's magnetic field lines) and true north (the direction along a meridian towards the geographic North Pole). This angle varies depending on position on the Earth's surface and changes over time. Somewhat more formally, Bowditch defines variation as “the angle between the magnetic and geographic meridians at any place, expressed in degrees and minutes east or west to indicate the direction of magnetic north from true north. The angle between magnetic and grid meridians is called grid magnetic angle, grid variation, or grivation.” By convention, declination is positive when magnetic north is east of true north, and negative when it is to the west. ''Isogonic lines'' are lines on the Earth's surface along which the declination has the same constant value, and line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1582 Deaths
Year 158 ( CLVIII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Tertullus and Sacerdos (or, less frequently, year 911 ''Ab urbe condita'').

William Bourne (mathematician)
William Bourne (c. 1535–1582) was an English mathematician, innkeeper and former Royal Navy gunner who presented the first design for a navigable submarine and wrote important navigational manuals. He is often called William Bourne of Gravesend. In 1574, he produced a popular version of the Martín Cortés de Albacar's '' Arte de Navegar,'' entitled ''A Regiment for the Sea.'' Bourne was critical of some aspects of the original and produced a manual of more practical use to the seaman. He described how to make observations of the sun and stars, using a cross-staff, and how to plot coastal features from the ship by taking bearings using triangulation.G. L'E. Turner, ‘Bourne, William (c.1535–1582)’, Oxford Dictionary of National Biography, Oxford University Press, 2004. Life in Gravesend Before publishing his submarine design, William Bourne was a jurat in Gravesend, England. His name first appears in the first charter of incorporation of Gravesend from June 5, 1562. His n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Astrolabe
The mariner's astrolabe, also called sea astrolabe, was an inclinometer used to determine the latitude of a ship at sea by measuring the sun's noon altitude (declination) or the meridian altitude of a star of known declination. Not an astrolabe proper, the mariner's astrolabe was rather a graduated circle with an alidade used to measure vertical angles. They were designed to allow for their use on boats in rough water and/or in heavy winds, which astrolabes are ill-equipped to handle. It was invented by the Portuguese people, a nation known for its maritime prowess and dominated the sea for multiple centuries. In the sixteenth century, the instrument was also called a ring. History Many dates can be found for the appearance of the first Mariner's astrolabes. The earliest date, 1295, is offered by the Majorcan astronomer Ramon Llull.''The Oxford Companion to Ships and the Sea'', Peter Kemp ed., 1976 Later dates center around the late 15th century, with Samuel Purchas clai ...

Nocturnal (instrument)
A nocturnal is an instrument used to determine the local time based on the relative positions of two or more stars in the night sky. Sometimes called a ''horologium nocturnum'' (time instrument for night) or ''nocturlabe'' (in French and occasionally used by English writers), it is related to the astrolabe and sundial. Knowing the time is important in piloting for calculating tides and some nocturnals incorporate tide charts for important ports. Even if the nightly course of the stars has been known since antiquity, mentions of a dedicated instrument for its measurement are not found before the Middle Ages. The earliest image presenting the use of a nocturnal is in a manuscript dated from the 12th century.Farre i Olive E., (1996): ''La Sphaera Horarum Noctis de Ramon Llull'', "La Busca de Paper" n. 22, Primavera, p. 3-12 (edicion bilingue) Raymond Lull repeatedly described the use of a ''sphaera horarum noctis'' or ''astrolabium nocturnum''.Raimon Lull, ''Liber Principorum medicin ...

Colgate University
Colgate University is a private liberal arts college in Hamilton, New York. The college was founded in 1819 as the Baptist Education Society of the State of New York and operated under that name until 1823, when it was renamed Hamilton Theological and Literary Institution, often called Hamilton College (1823–1846), then Madison College (1846–1890), and its present name since 1890. Colgate University is among the 100 most selective colleges and universities in the United States, and is considered a Hidden Ivy as well as one of the Little Ivies. In addition, Colgate campus is also consistently ranked as one of the most beautiful campuses in the nation due to a singular architectural theme of the campus and a hillside location adorned with a lake and trees. The university is located in Hamilton, New York, a small town in central New York in Madison County. Colgate now enrolls nearly 3,000 students in 56 undergraduate majors that culminate in a Bachelor of Arts degree. The stu ...

Celestial Pole
The north and south celestial poles are the two points in the sky where Earth's rotation around a fixed axis, axis of rotation, indefinitely extended, intersects the celestial sphere. The north and south celestial poles appear permanently directly overhead to observers at Earth's North Pole and South Pole, respectively. As Earth spins on its axis, the two celestial poles remain fixed in the sky, and all other celestial points appear to rotate around them, completing one circuit per day (strictly, per sidereal time, sidereal day). The celestial poles are also the poles of the celestial equatorial coordinate system, meaning they have declinations of +90 degrees and −90 degrees (for the north and south celestial poles, respectively). Despite their apparently fixed positions, the celestial poles in the long term do not actually remain permanently fixed against the background of the stars. Because of a phenomenon known as the precession of the equinoxes, the poles trace out ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Drake
Sir Francis Drake ( – 28 January 1596) was an English explorer, sea captain, privateer, slave trader, naval officer, and politician. Drake is best known for his circumnavigation of the world in a single expedition, from 1577 to 1580 (the first English circumnavigation, the second carried out in a single expedition, and third circumnavigation overall). This included his incursion into the Pacific Ocean, until then an area of exclusive Spanish interest, and his claim to New Albion for England, an area in what is now the U.S. state of California. His expedition inaugurated an era of conflict with the Spanish on the western coast of the Americas, an area that had previously been largely unexplored by Western shipping. He was Member of Parliament (MP) for three constituencies; Camelford in 1581, Bossiney in 1584, and Plymouth in 1593. Queen Elizabeth I of England, Elizabeth I awarded Drake a knighthood in 1581 which he received on the ''Golden Hind'' in Deptford. In the same ...

Cosmographer
The term cosmography has two distinct meanings: traditionally it has been the protoscience of mapping the general features of the cosmos, heaven and Earth; more recently, it has been used to describe the ongoing effort to determine the large-scale features of the observable universe. Traditional usage The 14th-century work '' 'Aja'ib al-makhluqat wa-ghara'ib al-mawjudat'' by Persian physician Zakariya al-Qazwini is considered to be an early work of cosmography. Traditional Hindu, Buddhist and Jain cosmography schematize a universe centered on Mount Meru surrounded by rivers, continents and seas. These cosmographies posit a universe being repeatedly created and destroyed over time cycles of immense lengths. In 1551, Martín Cortés de Albacar, from Zaragoza, Spain, published ''Breve compendio de la esfera y del arte de navegar''. Translated into English and reprinted several times, the work was of great influence in Britain for many years. He proposed spherical charts and ment ...
