John Earnshaw
John William Earnshaw (1900–1982) was a self-taught Australian engineer, and inventor. He also researched and wrote about Australian history. Life and career Earnshaw was born on 23 June 1900 in Randwick, New South Wales, the son of a noted Sydney horse trainer and dual Melbourne Cup winner Isaac Earnshaw (known as Ike). He served with the Royal Engineers in France during World War I. After the war, Earnshaw undertook many dangerous travels in Papua New Guinea. He married Evelyn Hall in Sydney in 1929. The couple had four daughters. Earnshaw set up a business, Reilax Engineering, which specialised in production-line problems. The business prospered for over 30 years in North Sydney, New South Wales, until he retired in 1969. He invented a number of machines for filling metal and glass containers for the food, cosmetics, chemical and pharmaceutical manufacturing industries. For the Red Cross Blood Bank, Earnshaw devised an oscillator for separating plasma from blood. He was a pio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australians
Australians, colloquially known as Aussies, are the citizens, nationals and individuals associated with the country of Australia. This connection may be residential, legal, historical or ethno-cultural. For most Australians, several (or all) of these connections exist and are collectively the source of their being Australian. Australian law does not provide for a racial or ethnic component of nationality, instead relying on citizenship as a legal status. Since the postwar period, Australia has pursued an official policy of multiculturalism and has the world's eighth-largest immigrant population, with immigrants accounting for 30 percent of the population in 2019. Between European colonisation in 1788 and the Second World War, the vast majority of settlers and immigrants came from the British Isles (principally England, Ireland and Scotland), although there was significant immigration from China and Germany during the 19th century. Many early settlements were initially pen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oscillator
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current. Oscillations can be used in physics to approximate complex interactions, such as those between atoms. Oscillations occur not only in mechanical systems but also in dynamic systems in virtually every area of science: for example the beating of the human heart (for circulation), business cycles in economics, predator–prey population cycles in ecology, geothermal geysers in geology, vibration of strings in guitar and other string instruments, periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy. The term ''vibration'' is precisely used to describe a mechanical oscillation. Oscillation, especially rapid oscillation, may be an undesirable phenomenon in pro ...

Short Story
A short story is a piece of prose fiction that typically can be read in one sitting and focuses on a self-contained incident or series of linked incidents, with the intent of evoking a single effect or mood. The short story is one of the oldest types of literature and has existed in the form of legends, mythic tales, folk tales, fairy tales, tall tales, fables and anecdotes in various ancient communities around the world. The modern short story developed in the early 19th century. Definition The short story is a crafted form in its own right. Short stories make use of plot, resonance, and other dynamic components as in a novel, but typically to a lesser degree. While the short story is largely distinct from the novel or novella/short novel, authors generally draw from a common pool of literary techniques. The short story is sometimes referred to as a genre. Determining what exactly defines a short story has been recurrently problematic. A classic definition of a short story ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabinetmaker
A cabinet is a case or cupboard with shelves and/or drawers for storing or displaying items. Some cabinets are stand alone while others are built in to a wall or are attached to it like a medicine cabinet. Cabinets are typically made of wood (solid or with veneers or artificial surfaces), coated steel (common for medicine cabinets), or synthetic materials. Commercial grade cabinets usually have a melamine-particleboard substrate and are covered in a high pressure decorative laminate, commonly referred to as Wilsonart or Formica. Cabinets sometimes have one or more doors on the front, which are mounted with door hardware, and occasionally a lock. Cabinets may have one or more doors, drawers, and/or shelves. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens. A cabinet intended to be used in a bedroom and with several drawers typically placed one above another in one or more column ...

David Collins (lieutenant Governor)
Colonel David Collins (3 March 1756 – 24 March 1810) was a British Marine officer who was appointed as Judge-Advocate to the new colony being established in Botany Bay. He sailed with Governor Arthur Phillip on the First Fleet to establish a penal colony at what is now Sydney. He became secretary to the first couple of Governors, later being appointed to start a secondary colony where he founded the city of Hobart as the founding Lieutenant Governor of Van Diemen's Land (later becoming the state of Tasmania). Early life and military career David Collins was born 3 March 1756 in London, the third and oldest surviving child of Arthur Tooker Collins (1718–1793), an officer of marines (later major-general) and Henrietta Caroline (died 1807) of King's County, Ireland.

Scottish Martyrs
The Political Martyrs Monument, located in the Old Calton Burial Ground on Calton Hill, Edinburgh, commemorates five political reformists from the late 18th and early 19th centuries. Designed by Thomas Hamilton and erected in 1844, it is a tall obelisk on a square-plan base plinth, all constructed in ashlar sandstone blocks. As part of the Burial Ground it is Category A listed. Inscriptions The monument is inscribed on one side: On another face are quotations from two of the men commemorated on the monument: History In 1837 the Radical politician Joseph Hume MP initiated a plan to erect a monument to the five men. Hume chaired a London-based committee to raise public subscriptions in support of the monument and settled on its location being in Edinburgh. In that year the publisher William Tait of Edinburgh wrote on their behalf to the Lord Provost of Edinburgh requesting that land be made available on Calton Hill for this end. The foundation stone was laid by Hume on 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthmoving Equipment
Heavy equipment or heavy machinery refers to Heavy-duty vehicle, heavy-duty vehicles specially designed to execute construction tasks, most frequently involving Earthworks (engineering), earthwork operations or other large construction tasks. ''Heavy equipment'' usually comprises five equipment systems: the Heavy_equipment#Implements_and_hydromechanical_work_tools, implement, Traction (engineering), traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC when the Roman engineering, ancient Roman engineer Vitruvius described a Roman crane, crane in ''De architectura'' when it was powered via human or animal labor. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses Hydraulic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Roller
A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations. Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion. History The first road rollers were horse-drawn, and were probably borrowed farm implements'' (see Roller)''. Since the effectiveness of a roller depends to a large extent on its weight, self-powered vehicles replaced horse-drawn rollers from the mid-19th century. The first such vehicles were steam rollers. Single-cylinder steam rollers were generally used for base compaction and run with high engine revs with low gearing to promote bounce and vibration from the crankshaft through to the rolls in much the same way as a vibrating roller. The double cylinder or compound steam rollers became popular from around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
