Dionysius Lardner
Dionysius Lardner FRS FRSE (3 April 179329 April 1859) was an Irish scientific writer who popularised science and technology, and edited the 133-volume '' Cabinet Cyclopædia''. Early life in Dublin He was born in Dublin on 3 April 1793 the son of William Lardner and his wife; his father was a solicitor in Dublin, who wished his son to follow the same calling. After some years of uncongenial desk work, Lardner entered Trinity College, Dublin, in 1812. He obtained a B.A. in 1817 and an M.A. in 1819, winning many prizes. He married Cecilia Flood on 19 December 1815, but they separated in 1820 and were divorced in 1835. About the time of the separation, he began a relationship with a married woman, Anne Maria Darley Boursiquot, the wife of a Dublin wine merchant of Huguenot ancestry. It is believed that he fathered her son, Dion Boucicault, who became an actor and dramatist. Lardner provided him with financial support until 1840. Whilst in Dublin, Lardner began to write and l ...

Dublin
Dublin is the capital and largest city of Republic of Ireland, Ireland. Situated on Dublin Bay at the mouth of the River Liffey, it is in the Provinces of Ireland, province of Leinster, and is bordered on the south by the Dublin Mountains, part of the Wicklow Mountains range. Dublin is the largest city by population on the island of Ireland; at the 2022 census of Ireland, 2022 census, the city council area had a population of 592,713, while the city including suburbs had a population of 1,263,219, County Dublin had a population of 1,501,500. Various definitions of a metropolitan Greater Dublin Area exist. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixth largest in Western Europ ...

Steam Engine
A steam engine is a heat engine that performs Work (physics), mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a Cylinder (locomotive), cylinder. This pushing force can be transformed by a connecting rod and Crank (mechanism), crank into rotational force for work. The term "steam engine" is most commonly applied to reciprocating engines as just described, although some authorities have also referred to the steam turbine and devices such as Hero's aeolipile as "steam engines". The essential feature of steam engines is that they are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including Boiler (power generation), boilers etc.), such as railway steam locomot ...

Dragoon Guards
Dragoon Guards is a designation that has been used to refer to certain heavy cavalry regiments in the British Army since the 18th century. While the Prussian and Russian armies of the same period included dragoon regiments among their respective Imperial Guards, different titles were applied to these units. Origins The British Army first used the designation in 1746, when the King's Own Regiment of Horse, the Queen's Own Royal Regiment of Horse (prior to 1727 the Princess of Wales's Own) and the 4th Horse were redesignated as the 1st, 2nd and 3rd Dragoon Guards respectively. In 1788 the four remaining regiments of Horse were converted into the 4th to 7th Dragoon Guards. At the beginning of the French Revolutionary War the British Army maintained seven regiments of Dragoon Guards, plus six of Dragoons and fourteen of Light Dragoons. During the 19th and early 20th centuries the seven regiments of Dragoon Guards were classed as medium cavalry while the three remaining Dragoon regiment ...

Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by Charles II of England, King Charles II and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the society's president, according to a set of statutes and standing orders. The members of Council and the president are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS (Fellow ...

Edinburgh Cabinet Library
The ''Edinburgh Cabinet Library'' was a series of 38 books, mostly geographical, published from 1830 to 1844, and edited by Dionysius Lardner. The original price was 5 shilling The shilling is a historical coin, and the name of a unit of modern currency, currencies formerly used in the United Kingdom, Australia, New Zealand, other British Commonwealth countries and Ireland, where they were generally equivalent to 1 ...s for a volume; a later reissue of 30 of the volumes was at half that price. The series was published jointly by Oliver and Boyd in Edinburgh, and Simpkin & Marshall in London, and in the years 1848 to 1851 was published in a new edition by Thomas Nelson & Sons.

Charles Vincent Walker
Charles Vincent Walker FRS (20 March 1812 – 24 December 1882) was an English electrical engineer and publisher, a major influence on the development of railway telecommunications, he was also the first person to send a submarine telegraph signal. Life Born Marylebone, Middlesex son to Vincent and Ann ''née'' Blake, Walker's elementary education and engineering training are uncertain. However, by 1838 he had acquired some knowledge of electricity and had helped to found the London Electrical Society. Walker was secretary and treasurer of the Society in its early days and edited its ''Proceedings'' from 1841 to 1843. He also founded the '' Electrical Magazine'', though only two volumes appeared in 1841–3.McConnell (2004) Also in 1841, Walker worked on the ''Manual of Electricity, Magnetism and Meteorology'' which formed part of Dionysius Lardner's ''Cabinet Cyclopedia''. Walker also published his own book on ''Electrotype Manipulation'', followed by his ''Electric Telegraph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Kater
Henry Kater FRS, FRAS (16 April 1777 – 26 April 1835) was a British physicist of German descent. Early life He was born at Bristol. At first he intended to study law; but he gave up the idea on his father's death in 1794. He entered the army, obtaining a commission in the 12th Regiment of Foot, then stationed in India, where he assisted William Lambton in the Great Trigonometric Survey. Failing health obliged him to return to England; and in 1808, then a lieutenant, he entered on a student career at the Senior Division of the new Royal Military College at High Wycombe. Shortly afterwards he was promoted to the rank of captain. In 1814 he retired on half-pay, and devoted the remainder of his life to scientific research. Scientist His first major contribution to science was the comparison of the merits of the Cassegrainian and Gregorian telescopes; Kater determined the latter to be an inferior design. His most substantial work was the invention of Kater's pendulum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumatics
Pneumatics (from Greek 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other pneumatic devices. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors, and hydraulic actuators. Pneumatics also has applications in dentistry, construction, mining, and other areas. History Although the early history of pneumatics is somewhat unclear, blowguns are often considered the earliest pneumatic device, being created independently by various indigenous groups around the world. Bellows are an early form of air compressor used primarily for smelting and forging. Ctesibius of Alexandria is often considered the father of pneum ...

Hydrostatics
Hydrostatics is the branch of fluid mechanics that studies fluids at hydrostatic equilibrium and "the pressure in a fluid or exerted by a fluid on an immersed body". The word "hydrostatics" is sometimes used to refer specifically to water and other liquids, but more often it includes both gases and liquids, whether compressible or incompressible. It encompasses the study of the conditions under which fluids are at rest in stable equilibrium. It is opposed to ''fluid dynamics'', the study of fluids in motion. Hydrostatics is fundamental to ''hydraulics'', the engineering of equipment for storing, transporting and using fluids. It is also relevant to geophysics and astrophysics (for example, in understanding plate tectonics and the anomalies of the Earth's gravitational field), to meteorology, to medicine (in the context of blood pressure), and many other fields. Hydrostatics offers physical explanations for many phenomena of everyday life, such as why atmospheric pressur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Southey
Robert Southey (; 12 August 1774 – 21 March 1843) was an English poet of the Romantic poetry, Romantic school, and Poet Laureate of the United Kingdom, Poet Laureate from 1813 until his death. Like the other Lake Poets, William Wordsworth and Samuel Taylor Coleridge, Southey began as a radical but became steadily more conservative as he gained respect for Britain and its institutions. Other romantics such as Lord Byron, Byron accused him of siding with the establishment for money and status. He is remembered especially for the poem "After Blenheim" and the original version of "Goldilocks and the Three Bears". Life Robert Southey was born in Wine Street, Bristol, to Robert Southey and Margaret Hill. He was educated at Westminster School, London (where he was expelled for writing an article in ''The Flagellant'', a magazine he originated,Margaret Drabble ed: ''The Oxford Companion to English Literature'' (6th edition, Oxford, 2000), about criticized the school's practice of ex ...

Ancient Greece
Ancient Greece () was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity (), that comprised a loose collection of culturally and linguistically related city-states and communities. Prior to the Roman period, most of these regions were officially unified only once under the Kingdom of Macedon from 338 to 323 BC. In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age collapse, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece, from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included the Golden Age of Athens and the Peloponnesian War.
