Henry Coddington
Henry Coddington (1798/9, Oldbridge, County Meath — 3 March 1845, Rome) was an Anglo-Irish natural philosopher, fellow and tutor of Trinity College, Cambridge and Church of England clergyman. Life Henry Coddington was the son of Latham Coddington, Rector of Timolin, Kildare. Admitted to Trinity College, Cambridge in 1816, Coddingtion graduated BA as Senior Wrangler in 1820, and first Smith's prizeman; proceeded M.A. in 1823, and obtained a fellowship and sub-tutorship in his college. He retired to the college living of Ware in Hertfordshire, and in the discharge of his clerical duties burst a blood-vessel, thereby fatally injuring his health. Coddington was vicar of Ware, Hertfordshire from 1832 to 1845. Advised to try a southern climate, he travelled abroad, and died at Rome 3 March 1845. Family He married a daughter of Dr. Batten, principal of Haileybury College, and left seven children. Legacy He wrote chiefly on optics, in particular ''An Elementary Treatise on Opt ...

Oldbridge
Oldbridge () is a townland near Drogheda in County Meath, Ireland. The area is home to the Boyne Navigation, the Battle of the Boyne Interpretive Centre and the southern half of the Mary McAleese Boyne Valley Bridge (which carries the M1 motorway). Navigation The townland represents the furthest tidal reach on the River Boyne at a point called the "Curly Hole". Curly Hole is also a fishing location. Prior to the 12th century, this was the lowest crossing point of the Boyne. The Abbey of Mellifont owned the lands and fisheries here at dissolution in 1539. It was described then as "''Oldebryge. 26 fishermen with 26 boats de Corrio (sc.corachs) paying £13.6.8''". The Irish coracle was used for salmon fishing at this location up to at least the first half of the 20th century. One of the last coracles made locally was made in 1928 by Michael O'Brien of Oldbridge, for Adolf Mahr director of the National Museum of Ireland.

Optics
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of optical instruments, instruments that use or Photodetector, detect it. Optics usually describes the behaviour of visible light, visible, ultraviolet, and infrared light. Light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the Classical electromagnetism, classical electromagnetic description of light, however complete electromagnetic descriptions of light are often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of Ray (optics), rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alumni Of Trinity College, Cambridge
Alumni (: alumnus () or alumna ()) are former students or graduates of a school, college, or university. The feminine plural alumnae is sometimes used for groups of women, and alums (: alum) or alumns (: alumn) as gender-neutral alternatives. The word comes from Latin, meaning nurslings, pupils or foster children, derived from "to nourish". The term is not synonymous with "graduates": people can be alumni without graduating, e.g. Burt Reynolds was an alumnus of Florida State University but did not graduate. The term is sometimes used to refer to former employees, former members of an organization, former contributors, or former inmates. Etymology The Latin noun means "foster son" or "pupil". It is derived from the Latin verb "to nourish". Separate, but from the same root, is the adjective "nourishing", found in the phrase '' alma mater'', a title for a person's home university. Usage in Roman law In Latin, is a legal term (Roman law) to describe a child placed in foste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1845 Deaths
Events January–March * January 1 – The Philippines began reckoning Asian dates by hopping the International Date Line through skipping Tuesday, December 31, 1844. That time zone shift was a reform made by Governor–General Narciso Claveria on August 16, 1844, in order to align the local calendars in the country with the rest of Asia as trade interests with Imperial China, Dutch East Indies and neighboring countries increased, after Mexico became independent in 1821. The reform also applied to Caroline Islands, Guam, Marianas Islands, Marshall Islands, and Palau as part of the Captaincy General of the Philippines. * January 10 – Elizabeth Barrett receives a love letter from the younger poet Robert Browning; on May 20, they meet for the first time in London.

1790s Births
Year 179 ( CLXXIX) was a common year starting on Thursday of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelius and Veru (or, less frequently, year 932 ''Ab urbe condita''). The denomination 179 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Pencil (optics)
In optics, a pencil or pencil of rays, also known as a pencil beam or narrow beam, is a geometric construct ( pencil of half-lines) used to describe a beam or portion of a beam of electromagnetic radiation or charged particles, typically in the form of a cone or cylinder. Antennas which strongly bundle in azimuth and elevation are often described as "pencil-beam" antennas. For example, a phased array antenna can send out a beam that is extremely thin. Such antennas are used for tracking radar, and the process is known as beamforming. In optics, the focusing action of a lens is often described in terms of pencils of rays. In addition to conical and cylindrical pencils, optics deals with astigmatic pencils as well. In electron optics, scanning electron microscopes use narrow pencil beams to achieve a deep depth of field. Ionizing radiation used in radiation therapy, whether photons or charged particle In physics, a charged particle is a particle with an electric charg ...

Circle Of Confusion
In optics, a circle of confusion (CoC) is an optical spot caused by a cone of light ray (optics), rays from a lens (optics), lens not coming to a perfect focus (optics), focus when imaging a Point source#Light, point source. It is also known as disk of confusion, circle of indistinctness, blur circle, or blur spot. In photography, the circle of confusion is used to determine the depth of field, the part of an image that is acceptably sharp. A standard value of CoC is often associated with each film format, image format, but the most appropriate value depends on visual acuity, viewing conditions, and the amount of enlargement. Usages in context include ''maximum permissible circle of confusion'', ''circle of confusion diameter limit'', and the ''circle of confusion criterion''. Real lenses defocus, do not focus all rays perfectly, so that even at best focus, a point is imaged as a spot rather than a point. The smallest such spot that a lens can produce is often referred to as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
