Hargrave Cellular Wing
Lawrence Hargrave, MRAeS, (29 January 18506 July 1915) was a British-born Australian engineer, explorer, astronomer, inventor and aeronautical pioneer. Biography Lawrence Hargrave was born in Greenwich, England, the second son of John Fletcher Hargrave (later Attorney-General of NSW), and was educated at Queen Elizabeth's Grammar School, Kirkby Lonsdale, Westmorland, where there is now a building named in his honour. He immigrated to Australia at fifteen years of age with his family, arriving in Sydney on 5 November 1865 on the ''La Hogue''. He accepted a place on the ''Ellesmere'' and circumnavigated Australia. Although he had shown ability in mathematics at his English school he failed the matriculation examination and in 1867 took an engineering apprenticeship with the Australasian Steam Navigation Company in Sydney. He later found the experience of great use in constructing his models and his theories. In 1872, as an engineer, he sailed on the ''Maria'' on a vo ...

Greenwich
Greenwich ( , ,) is a town in south-east London, England, within the ceremonial county of Greater London. It is situated east-southeast of Charing Cross. Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban C ...

William John Macleay
Sir William John Macleay (13 June 1820 – 7 December 1891) was a Scottish-Australian politician, Natural history, naturalist, zoologist, and Herpetology, herpetologist. Early life Macleay was born at Wick, Highland, Wick, Caithness, Scotland, second son of Kenneth Macleay of Keiss and his wife Barbara, ''née'' Horne. Macleay was educated at the Edinburgh Academy 1834–36 and then to studied medicine at the University of Edinburgh; but when he was 18 years old his widowed mother died, and he decided to go to Australia with his cousin, William Sharp MacLeay. They arrived at Sydney in March 1839 on HMS Royal George (1827), HMS ''Royal George''. William Macleay took up land at first near Goulburn, New South Wales, Goulburn, and afterwards on the Murrumbidgee River. He is noted as the last of the naturalists in a family active in this field; his uncle was Alexander Macleay, Colonial Secretary of New South Wales from 1826 to 1836, and a member and fellow of societies concerned wit ...

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Paragliding
Paragliding is the recreational and competitive adventure sport of flying paragliders: lightweight, free-flying, foot-launched glider aircraft with no rigid primary structure. The pilot sits in a harness or lies supine in a cocoon-like 'pod' suspended below a fabric wing. Wing shape is maintained by the suspension lines, the pressure of air entering vents in the front of the wing, and the aerodynamic forces of the air flowing over the outside. Despite not using an engine, paraglider flights can last many hours and cover many hundreds of kilometres, though flights of one to two hours and covering some tens of kilometres are more the norm. By skillful exploitation of sources of lift, the pilot may gain height, often climbing to altitudes of a few thousand metres. History In 1966, Canadian Domina Jalbert was granted a patent for a ''multi-cell wing type aerial device—''"a wing having a flexible canopy constituting an upper skin and with a plurality of longitudinally extend ...

Hang Gliding
Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to soar for hours, gain thousands of feet of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the safety benefits of being instructed is highly recommended and indeed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanwell Park, New South Wales
Stanwell Park is a coastal village and northern suburb of Wollongong, New South Wales, Australia. It is the northernmost point of the Illawarra coastal strip and lies south of Sydney's Royal National Park. It is situated in a small valley between Bald Hill to the north, Stanwell Tops to the west and Mount Mitchell to the south. It has two lagoons from the village's two creeks, Stanwell and Hargrave Creeks and a beach running between headlands. Stanwell Park and the surrounding suburbs are colloquially referred to by its postcode 2508. History Stanwell Park was the name given to the farm established on the grant given to Matthew John Gibbons in 1824. He was given most of the area called ''Little Bulli'' which included present-day Stanwell Park and Coalcliff. The whole of Northern Illawarra went under the Aboriginal name Bulli. Bulli remains the name of an Illawarra suburb further south of Stanwell Park. The area was originally inhabited by the Wodiwodi Aboriginal clan o ...

Sydney Observatory
The Sydney Observatory is a heritage-listed meteorological station, astronomical observatory, function venue, science museum, and education facility located on Observatory Hill at Upper Fort Street, in the inner city Sydney suburb of Millers Point in the City of Sydney local government area of New South Wales, Australia. It was designed by William Weaver (plans) and Alexander Dawson (supervision) and built from 1857 to 1859 by Charles Bingemann & Ebenezer Dewar.

Pearl Hunting
Pearl hunting, also known as pearling, is the activity of recovering pearls from wild molluscs, usually oysters or mussels, in the sea or freshwater. Pearl hunting was prevalent in the Persian Gulf region and Japan for thousands of years. On the northern and north-western coast of Western Australia pearl diving began in the 1850s, and started in the Torres Strait Islands in the 1860s, where the term also covers diving for nacre or mother of pearl found in what were known as pearl shells. In most cases the pearl-bearing molluscs live at depths where they are not manually accessible from the surface, and diving or the use of some form of tool is needed to reach them. Historically the molluscs were retrieved by freediving, a technique where the diver descends to the bottom, collects what they can, and surfaces on a single breath. The diving mask improved the ability of the diver to see while underwater. When the surface-supplied diving helmet became available for underwater work, it ...
