Herbert Bowyer Berkeley
Herbert Bowyer Berkeley (27 March 1851 – 26 May 1890) was an English photographer as well as a chemical engineer. He was the fourth son of The Reverend William Comyns Berkeley and Harriet Elizabeth Bowyer Nichols Berkeley. Berkeley was educated at Uppingham School, was a member of the Royal Photographic Society and exhibited work from 1874 until 1889. Early life Herbert Bowyer Berkeley was born on 27 March 1851 at Cotheridge Court, Cotheridge, Worcestershire, England. During his years at Uppingham he was introduced to chemistry by his science teacher, a German PhD. After Uppingham he lived at Cotheridge Court. During the 1870s he became an amateur photographer as well as a chemical engineer, and experimented with the developing processes and photographic materials available to him during that time. Many of his early photographs were scenes taken around the extensive woods and pastures in the vicinity of his family home. By early 1881 he had left Cotheridge and was living in l ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Photographers From Worcestershire
A photographer (the Greek φῶς (''phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light") is a person who makes photographs. Duties and types of photographers As in other arts, the definitions of amateur and professional are not entirely categorical. An ''amateur photographer'' takes snapshots for pleasure to remember events, places or friends with no intention of selling the images to others. A ''professional photographer'' is likely to take photographs for a session and image purchase fee, by salary or through the display, resale or use of those photographs. A professional photographer may be an employee, for example of a newspaper, or may contract to cover a particular planned event such as a wedding or graduation, or to illustrate an advertisement. Others, like fine art photographers, are freelancers, first making an image and then licensing or making printed copies of it for sale or display. Some ...

1890 Deaths
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Silanus and Silanus (or, less frequently, year 942 ''Ab urbe condita''). The denomination 189 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.

Dove Valley
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Willis (inventor)
William Willis Jr. (1841–1923) is a British inventor who developed the platinum printing process, an early form of photography, based on the light sensitivity of platinum salts, originally discovered by John Herschel. Willis made the first platinum print in 1873 and patented it, but the process was imperfect, attracting little interest. In 1874, the British Journal of Photography announced his Platinum Printing process. It gave a report of the process on 4 June 1875. By 1879 he had improved the process sufficiently to justify founding the Platinotype Company to market his papers. He began marketing his pre-coated papers in 1880. Taking his cue from Daguerre's marketing practices with his Daguerreotypes, Willis sold licenses to photographers wanting to use his process, and then sold them the materials. He lived for many years in Bromley (Kent) and took a considerable interest in the nearby local cottage hospital to which he donated land and funds as well as buying their first X ...

Alkaline
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a base (chemistry), basic, ionic compound, ionic salt (chemistry), salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English language, English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the acid-base reaction theories#Arrhenius theory, Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formula
In science, a formula is a concise way of expressing information symbolically, as in a mathematical formula or a ''chemical formula''. The informal use of the term ''formula'' in science refers to the general construct of a relationship between given quantities. The plural of ''formula'' can be either ''formulas'' (from the most common English plural noun form) or, under the influence of scientific Latin, ''formulae'' (from the original Latin). In mathematics In mathematics, a formula generally refers to an identity which equates one mathematical expression to another, with the most important ones being mathematical theorems. Syntactically, a formula (often referred to as a ''well-formed formula'') is an entity which is constructed using the symbols and formation rules of a given logical language. For example, determining the volume of a sphere requires a significant amount of integral calculus or its geometrical analogue, the method of exhaustion. However, having done t ...

Uppingham School
Uppingham School is a public school (English independent day and boarding school for pupils 13-18) in Uppingham, Rutland, England, founded in 1584 by Robert Johnson (rector), Robert Johnson, the Archdeacon of Leicester, who also established Oakham School. The headmaster, Richard J. Maloney, belongs to the Headmasters Conference, Headmasters' and Headmistresses' Conference and the school to the Rugby Group of independent school (UK), British independent schools. Edward Thring was perhaps the school's best-known headmaster (in 1853–1887). His curriculum changes were adopted in other English public schools. John Wolfenden, headmaster from 1934 to 1944, chaired the Wolfenden Committee, whose report recommending the decriminalisation of homosexuality appeared in 1957. Uppingham has a musical tradition based on work by Paul David and Robert Sterndale Bennett. It has the biggest playing-field area of any school in England, in three separate areas of the town: Leicester to the west, M ...

Citric Acid
Citric acid is an organic compound with the chemical formula HOC(CO2H)(CH2CO2H)2. It is a colorless weak organic acid. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. More than two million tons of citric acid are manufactured every year. It is used widely as an acidifier, as a flavoring, and a chelating agent. A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solution. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When part of a salt, the formula of the citrate anion is written as or . Natural occurrence and industrial production Citric acid occurs in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in ...
