Henry Foster (scientist)
Henry Foster (1797 – 5 February 1831) was a Royal Navy, British naval officer and scientist who took part in expeditions to both the Arctic and Antarctic, and made notable scientific contributions to studies of the figure of the earth and the earth's magnetic field. Career Foster was the eldest son of the Rev. Henry Foster of Woodplumpton, Lancashire. He joined the Royal Marines in 1812, serving first aboard . In 1817 he joined in which he surveyed the mouth of the Columbia River. In 1819 he joined HMS ''Creole'', and carried out a survey of the north shore of the Río de la Plata. From 1820-1822 he served on , commanded by Basil Hall, first as midshipman, then as Master's mate, on a yoyage to South America. In his journal of the voyage, Hall refers to Foster as an "admirable surveyor". Foster carried out a survey of the Caldera, Chile, harbour of Copiapó, and prepared a Hydrographical Memoir, with details of all the ports visited on the voyage. During the voyage, Hall and Fo ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

John Herschel
Sir John Frederick William Herschel, 1st Baronet (; 7 March 1792 – 11 May 1871) was an English polymath active as a mathematician, astronomer, chemist, inventor and experimental photographer who invented the blueprint and did botanical work. Herschel originated the use of the Julian day system in astronomy. He named seven moons of Saturn and four moons of Uranus – the seventh planet, discovered by his father Sir William Herschel. He made many contributions to the science of photography, and investigated colour blindness and the chemical power of ultraviolet rays. His ''Preliminary Discourse'' (1831), which advocated an Inductive reasoning, inductive approach to scientific experiment and theory-building, was an important contribution to the philosophy of science. Early life and work on astronomy Herschel was born in Slough, Buckinghamshire, the son of Mary Baldwin and astronomer Sir William Herschel. He was the nephew of astronomer Caroline Herschel. He studied short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Beaufort
Sir Francis Beaufort ( ; 27 May 1774 – 17 December 1857) was an Irish hydrographer and naval officer who created the Beaufort cipher and the Beaufort scale. Early life Francis Beaufort was descended from French Protestant Huguenots, who fled the French Wars of Religion in the sixteenth century. His parents moved to Ireland from London. His father, Daniel Augustus Beaufort, was a Protestant clergyman from Navan, County Meath, Ireland, and a member of the learned Royal Irish Academy. His mother Mary was the daughter and co-heiress of William Waller, of Allenstown House. Francis was born in Navan on 27 May 1774. He had an older brother, William Louis Beaufort and three sisters, Frances, Harriet, and Louisa. His father created and published a new map of Ireland in 1792. Francis grew up in Wales and Ireland until age fourteen. He left school and went to sea, but never stopped his education. By later in life, he had become sufficiently self-educated to associate ...

Copley Medal
The Copley Medal is the most prestigious award of the Royal Society of the United Kingdom, conferred "for sustained, outstanding achievements in any field of science". The award alternates between the physical sciences or mathematics and the biological sciences. It is arguably the highest United Kingdom, British and Commonwealth of Nations, Commonwealth award for scientific achievement, and has often been included among the most distinguished international scientific awards. Given annually, the medal is the oldest Royal Society medal awarded and the oldest surviving scientific award in the world, having first been given in 1731 to Stephen Gray (scientist), Stephen Gray, for "his new Electrical Experiments: – as an encouragement to him for the readiness he has always shown in obliging the Society with his discoveries and improvements in this part of Natural Knowledge". The medal is made of silver-gilt and awarded with a £25,000 prize. It is awarded to "senior scientists" irres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth's Magnetic Field
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from structure of Earth, Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole (Ellesmere Island, Nunavut, Canada) actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic ...

Occultations
An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks from view (occults) an object in the background. In this general sense, occultation applies to the visual scene observed from low-flying aircraft (or computer-generated imagery) when foreground objects obscure distant objects dynamically, as the scene changes over time. If the closer body does not entirely conceal the farther one, the event is called a ''transit''. Both transit and occultation may be referred to generally as ''occlusion''; and if a shadow is cast onto the observer, it is called an eclipse. The symbol for an occultation, and especially a solar eclipse, is 🝵 (U+1F775 🝵). Occultations by the Moon The term occultation is most frequently used to describe lunar occultations, those relatively frequent occasions when ...

Lunar Distance (navigation)
In celestial navigation, lunar distance, also called a ''lunar'', is the angular distance between the Moon and another celestial body. The lunar distances method uses this angle and a nautical almanac to calculate Greenwich time if so desired, or by extension any other time. That calculated time can be used in solving a spherical triangle. The theory was first published by Johannes Werner in 1524, before the necessary almanacs had been published. A fuller method was published in 1763 and used until about 1850 when it was superseded by the marine chronometer. A similar method uses the positions of the Galilean moons of Jupiter. Purpose In celestial navigation, knowledge of the time at Greenwich (or another known place) and the measured positions of one or more celestial objects allows the navigator to calculate longitude. Reliable marine chronometers were unavailable until the late 18th century and not affordable until the 19th century. After the method was firs ...

Transit Instrument
In astronomy, a transit instrument is a small telescope with an extremely precisely graduated mount used for the precise observation of star positions. They were previously widely used in astronomical observatories and naval observatories to measure star positions in order to compile nautical almanacs for use by mariners for celestial navigation, and observe star transits to set extremely accurate clocks ( astronomical regulators) which were used to set marine chronometers carried on ships to determine longitude, and as primary time standards before atomic clocks. The instruments can be divided into three groups: meridian, zenith, and universal instruments. Types Meridian instruments For observation of star transits in the exact direction of South or North: * Meridian circles, Mural quadrants etc. * Passage instruments (transportable, also for prime vertical transits) Zenith instruments * Zenith telescope * Photozenith tube (PZT) * zenith cameras * Danjon astrolab ...

Prince Regent Inlet
Prince Regent Inlet () is a body of water in Nunavut, Canada between the west end of Baffin Island ( Brodeur Peninsula) and Somerset Island on the west. It opens north into Lancaster Sound and to the south merges into the Gulf of Boothia. The Arctic inlet's northern portion is approximately wide; the southern portion is approximately wide. It is deep throughout and there are no islands within the inlet. During the quest for the Northwest Passage it was entered several times until it was realized that Prince Regent Inlet-Gulf of Boothia is a cul-de-sac for practical purposes. In 1819 William Edward Parry Sir William Edward Parry (19 December 1790 – 8 July 1855) was a Royal Navy officer and explorer best known for his 1819–1820 expedition through the Parry Channel, probably the most successful in the long quest for the Northwest Passa ... penetrated more than 100 miles south before turning back.
