Norman Collie
Professor John Norman Collie FRSE FRS (10 September 1859 – 1 November 1942), commonly referred to as J. Norman Collie, was an English scientist, mountaineer and explorer. Life and work He was born in Alderley Edge, Cheshire, the second of four sons to John Collie and Selina Mary Winkworth. In 1870 the family moved to Clifton, near Bristol, and John was educated initially at Windlesham in Surrey and then in 1873 at Charterhouse School. The family money had been made in the cotton trade, but in 1875 the American Civil War resulted in their financial ruin when their American stock was burnt. Collie had to leave Charterhouse and transfer to Clifton College, Bristol where he realised he was completely unsuited for the classics. He attended University College in Bristol and developed an interest in chemistry. He earned a PhD in chemistry under Johannes Wislicenus at Würzburg in 1884. Returning to Britain, he taught three years at Cheltenham Ladies College where, according to hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alderley Edge
Alderley Edge is a village and civil parish in Cheshire, England. In 2011, it had a population of 4,780. Alderley Edge is northwest of Macclesfield and south of Manchester, at the base of a steep and thickly wooded sandstone escarpment, Alderley Edge, which is the area's chief topographical feature and overlooks the Cheshire Plain. Alderley Edge is known for its affluence and expensive houses, falling inside Cheshire's Golden Triangle.

William Cecil Slingsby
William Cecil Slingsby (1849–1929) was an English mountain climber and alpine explorer from Carleton, North Yorkshire. Born in Bell Busk, near Gargrave, Yorkshire, Slingsby first visited Norway in 1872 and fell in love with the country. He has been called the discoverer of the Norwegian mountains, and the father of Norwegian mountaineering (insofar as he seems to be the first who actively pursued climbing in Norway and was the first person on several mountains). Together with Norway's early skilled mountain climber Kristian Bing (1862–1935), he is considered to have been a pioneer explorer of Jostedalsbreen, the largest glacier in continental Europe. Slingsby is perhaps most famous for being the first on "Storen", or Store Skagastølstind ( in 1876, the third highest mountain in Norway. It was considered impossible to climb then, but Slingsby defied popular notion and climbed the mountain, for the last part alone. Slingsby also attempted to climb the 1392 metres tall and h ...

Lake District
The Lake District, also known as the Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes, forests, and mountains (or ''fells''), and its associations with William Wordsworth and other Lake Poets and also with Beatrix Potter and John Ruskin. The Lake District National Park was established in 1951 and covers an area of . It was designated a UNESCO World Heritage Site in 2017. The Lake District is today completely within Cumbria, a county and administrative unit created in 1974 by the Local Government Act 1972. However, it was historically divided between three English counties ( Cumberland, Westmorland and Lancashire), sometimes referred to as the Lakes Counties. The three counties met at the Three Shire Stone on Wrynose Pass in the southern fells west of Ambleside. All the land in England higher than above sea level lies within the National Park, including Scafell Pike, the highest mountain in England. ...

Cuillin
The Cuillin ( gd, An Cuiltheann) is a range of mostly jagged rocky mountains on the Isle of Skye in Scotland. The main Cuillin ridge is also called the Black Cuillin to distinguish it from the Red Cuillin ('), which lie to the east of Glen Sligachan.R. Anderson & Tom Prentice. ''The Grahams & The Donalds - Scottish Mountaineering Club Hillwalkers' Guide'', pp. 304–309. Published 2015. The peaks of the Black Cuillin are mainly composed of gabbro, a very rough igneous rock which provides a superb grip for mountaineers; and basalt, which can be very slippery when wet.D. Bennet & R. Anderson. ''The Munros: Scottish Mountaineering Club Hillwalkers Guide'', pp. 258-275. Published 2016. The rocks forming the ridge of the Black Cuillin (and outliers such Blà Bheinn) are dark, particularly in the shade, but when in sunlight the Black Cuillin can appear grey to brown. The main ridge forms a narrow crest, with steep cliffs and scree slopes. The ridge is about 14 km long (from Gars-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avocation
An avocation is an activity that someone engages in as a hobby outside their main occupation. There are many examples of people whose professions were the ways that they made their livings, but for whom their activities outside their workplaces were their true passions in life. Occasionally, as with Lord Baden-Powell and others, people who pursue an avocation are more remembered by history for their avocation than for their professional career. Many times a person's regular vocation may lead to an avocation. Many forms of humanitarian campaigning, such as work for organizations like Amnesty International and Greenpeace, may be done by people involved in the law or human rights issues as part of their work. Many people involved with youth work pursue this as an avocation. Avocation in literature People whose avocations were not their vocations A B C D E F G H I J K L M N O P Q R S T U V ...

Collie And MacKenzie
Collies form a distinctive type of herding dogs, including many related landraces and standardized breeds. The type originated in Scotland and Northern England. Collies are medium-sized, fairly lightly-built dogs, with pointed snouts. Many types have a distinctive white color over the shoulders. Collies are very active and agile, and most types of collies have a very strong herding instinct. Collie breeds have spread through many parts of the world (especially Australia and North America), and have diversified into many varieties, sometimes mixed with other dog types. Some collie breeds have remained as working dogs for herding cattle, sheep, and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability. While the American Kennel Club has a breed they call "collie", in fact ''collie dogs'' are a distinctive type of herding dog inclusive of many related landraces and formal breeds. There are usua ...

Oxonium Ion
In chemistry, an oxonium ion is any cation containing an oxygen atom that has three bonds and 1+ formal charge. The simplest oxonium ion is the hydronium ion (). Alkyloxonium Hydronium is one of a series of oxonium ions with the formula R''n''H3−''n''O+. Oxygen is usually pyramidal with an sp3 hybridization. Those with ''n'' = 1 are called primary oxonium ions, an example being protonated alcohol (e.g. methanol). In acidic media, the oxonium functional group produced by protonating an alcohol can be a leaving group in the E2 elimination reaction. The product is an alkene. Extreme acidity, heat, and dehydrating conditions are usually required. Other hydrocarbon oxonium ions are formed by protonation or alkylation of alcohols or ethers (R−C−−R1R2). Secondary oxonium ions have the formula R2OH+, an example being protonated ethers. Tertiary oxonium ions have the formula R3O+, an example being trimethyloxonium. Tertiary alkyloxonium salts are useful alkylating a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzene
Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is a natural constituent of petroleum and is one of the elementary petrochemicals. Due to the cyclic continuous pi bonds between the carbon atoms, benzene is classed as an aromatic hydrocarbon. Benzene is a colorless and highly flammable liquid with a sweet smell, and is partially responsible for the aroma of gasoline. It is used primarily as a precursor to the manufacture of chemicals with more complex structure, such as ethylbenzene and cumene, of which billions of kilograms are produced annually. Although benzene is a major industrial chemical, it finds limited use in consumer items because of its toxicity. History Discovery The word "''benzene''" derives from "''gum benzoin''" (benzoin res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dehydroacetic Acid
Dehydroacetic acid is an organic compound which has several industrial applications. The compound is classified as a pyrone derivative. It presents as an odorless, colorless to white crystalline powder, almost insoluble in water and moderately soluble in most organic solvents. Preparation It is prepared by the base-catalysed dimerization of diketene. Commonly used organic bases include imidazole, DABCO, and pyridine. Uses Industrially, dehydroacetic acid has several uses which include the following: * as a fungicide and bactericide. The sodium salt, sodium dehydroacetate, is often used in place of dehydroacetic acid because of its greater solubility in water. * as a food preservative to prevent pickle bloating in squash and strawberries. When used as a food additive, dehydroacetic acid is referred to using the International Numbering System for Food Additives or E number E numbers ("E" stands for "Europe") are codes for substances used as food additives, includ ...
