Australian Inventions
This is a timeline of Australian inventions consisting of products and technology invented in Australia from pre-European-settlement in 1788 to the present. The inventions are listed in chronological order based on the date of their introduction. Australian inventions include the very old, such as woomera, and the very new, such as the scramjet, first fired at the Woomera rocket range. The Australian government has suggested that Australian inventiveness springs from the nation's geography and isolation. Perhaps due to its status as an island continent connected to the rest of the world only via air and sea, Australians have been leaders in inventions relating to both maritime and aeronautical matters, including powered flight, the black box flight recorder, the inflatable escape slide, the surf ski and the wave-piercing catamaran winged keel. Since the earliest days of European settlement, Australia's main industries have been agriculture and mining. As a result of this, Aus ...

Stump-jump Plough
The stump-jump plough, also known as stump-jumping plough, is a kind of plough invented in South Australia in the late 19th century by Richard Bowyer Smith and Clarence Herbert Smith to solve the particular problem of preparing mallee lands for cultivation. The problem Mallee scrub originally covered large parts of southern Australia, and because of its growth habit, the trees were difficult to remove completely, because the tree would shoot again after burning, cutting down or other kinds of damage. The large roots, known as lignotubers, remained in the ground, making it very difficult to plough the soil. In South Australia, crown land was offered under the '' Scrub Lands Act 1866'' to farmers on lease, with the option of purchasing after 21 years at the price of £1 per acre. The " Strangways Act" followed in 1869, which allowed crown land to be bought on credit, with encouragement to clear the land of scrub for the purpose of more intensive agriculture such as growing grain ...

Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, ...

Mokare
Mokare (c. 1800 - 26 June 1831) was a Noongar Aboriginal man from the south-west corner of Australia, who was pivotal in aiding European exploration of the area. Life Mokare was from the Minang clan of Noongar people. He had at least two brothers: Mollian (d. 1829), who may have been known as Yallapoli, and Nakina, who like Mokare, became a frequent visitor to the settlement at King George Sound (now Albany). He also had a married sister. Mokare was probably the same man who met Phillip Parker King when his ship stopped at King George Sound in 1821. "Jack", as King called the man, was a charismatic intermediary between the ship's crew and Noongar people who visited the ship. In 1826 Mokare met the crew of the French barge ''Astrolabe'' who passed the area during their voyage to circumnavigate the world. In 1827 Major Edmund Lockyer arrived at King George Sound in the brig ''Amity'', to found a penal settlement at King George Sound. Mokare showed Lockyer and other Eu ...

Didgeridoo Entier1
The didgeridoo (; also spelt didjeridu, among other variants) is a wind instrument, played with vibrating lips to produce a continuous drone while using a special breathing technique called circular breathing. The didgeridoo was developed by Aboriginal peoples of northern Australia at least 1,000 years ago, and is now in use around the world, though still most strongly associated with Indigenous Australian music. In the Yolŋu languages of the indigenous people of northeast Arnhem Land the name for the instrument is the ''yiḏaki'', or more recently by some, ''mandapul''. In the Bininj Kunwok language of West Arnhem Land it is known as ''mako''. A didgeridoo is usually cylindrical or conical, and can measure anywhere from long. Most are around long. Generally, the longer the instrument, the lower its pitch or key. Flared instruments play a higher pitch than unflared instruments of the same length. History There are no reliable sources of the exact age of the didgeridoo. Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Scientific And Industrial Research Organisation
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aboriginal People Of Australia
Aboriginal Australians are the various Indigenous peoples of the Australian mainland and many of its islands, such as Tasmania, Fraser Island, Hinchinbrook Island, the Tiwi Islands, and Groote Eylandt, but excluding the Torres Strait Islands. The term Indigenous Australians refers to Aboriginal Australians and Torres Strait Islanders collectively. It is generally used when both groups are included in the topic being addressed. Torres Strait Islanders are ethnically and culturally distinct, despite extensive cultural exchange with some of the Aboriginal groups. The Torres Strait Islands are mostly part of Queensland but have a separate governmental status. Aboriginal Australians comprise many distinct peoples who have developed across Australia for over 50,000 years. These peoples have a broadly shared, though complex, genetic history, but only in the last 200 years have they been defined and started to self-identify as a single group. Australian Aboriginal identity has chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Unaipon
David Ngunaitponi (28 September 1872 – 7 February 1967), known as David Unaipon, was an Aboriginal Australian man of the Ngarrindjeri people. He was a preacher, inventor and author. Unaipon's contribution to Australian society helped to break many Aboriginal Australian stereotypes, and he is featured on the Australian $50 note in commemoration of his work. He was the son of preacher and writer James Unaipon. Biography Born at the Point McLeay Mission on the banks of Lake Alexandrina in the Coorong region of South Australia, Unaipon was the fourth of nine children of James and Nymbulda Ngunaitponi, of the Portaulun branch of the Ngarrindjeri people. Unaipon began his education at the age of seven at the Point McLeay Mission School and soon became known for his intelligence, with the former secretary of the Aborigines' Friends' Association stating in 1887: "I only wish the majority of white boys were as bright, intelligent, well-instructed and well-mannered, as the little ...

Vegemite
Vegemite ( ) is a thick, dark brown Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Cyril Callister in Melbourne, Victoria, in 1922. A spread for sandwiches, toast, crumpets and cracker biscuits as well as a filling for pastries, Vegemite is similar to British Marmite, New Zealand Marmite, Australian Promite, MightyMite, AussieMite, OzEmite, German Vitam-R, and Swiss Cenovis. Vegemite is salty, slightly bitter, malty, and rich in glutamates – giving it an umami flavour similar to beef bouillon. It is vegan, kosher, and ''halal''. The Vegemite brand returned to Australian ownership in 2017 when Bega Cheese purchased it alongside other assets from Mondelez International (formerly Kraft Foods Inc.). History Beginnings In 1919, following the disruption of British Marmite imports after World War I, the Australian company Fred Walker & Co. gave Cyril Callister the task of developing a ...

Zanamivir
Zanamivir is a medication used to treat and prevent influenza caused by influenza A and influenza B viruses. It is a neuraminidase inhibitor and was developed by the Australian biotech firm Biota Holdings. It was licensed to Glaxo in 1990 and approved in the US in 1999, only for use as a treatment for influenza. In 2006, it was approved for prevention of influenza A and B. Zanamivir was the first neuraminidase inhibitor commercially developed. It is marketed by GlaxoSmithKline under the trade name Relenza as a powder for oral inhalation. Medical uses Zanamivir is used for the treatment of infections caused by influenza A and influenza B viruses, but in otherwise-healthy individuals, benefits overall appear to be small. It decreases the risk of one's getting symptomatic, but not asymptomatic influenza. The combination of diagnostic uncertainty, the risk for virus strain resistance, possible side effects and financial cost outweigh the small benefits of zanamivir for the prophylax ...

Spray-on Skin
Spray-on skin is a skin culturing treatment for burn, or other skin damage victims. It involves taking small samples of the patient's skin and spraying them on the wound. History The treatment was developed by Marie Stoner and plastic surgeon Fiona Wood. Their technique worked quicker than previous skin culturing techniques. Wood established the company Avita Medical in 1993 to commercialise the procedure. After the 2002 Bali bombings, Wood used the experimental technology on victims before it had been subjected to proper clinical trials, garnering criticism from other burn specialists since at the time there was little evidence of its efficacy, and Wood had an apparent conflict of interest since she founded the company that sold the technology. A 2006 clinical trial Clinical trials are prospective biomedical or behavioral research studies on human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (su ...

Pacemaker
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or pacemaker is a medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and pump blood. By doing so, the pacemaker regulates the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's natural pacemaker is not fast enough, or because there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist, particularly a cardiac electrophysiologist, to select the optimal pacing modes for individual patients. Most pacemakers are on demand, in which the stimulation of the heart is based on the dynamic demand of the circulatory system. Others send out a fixed rate of ...

Corrective Lens
A corrective lens is a lens (i.e. a transmissive optical device) that is typically worn in front of the eye to improve daily vision. The most common use is to treat refractive errors: myopia, hypermetropia, astigmatism, and presbyopia. Glasses or "spectacles" are worn on the face a short distance in front of the eye. Contact lenses are worn directly on the surface of the eye. Intraocular lenses are surgically implanted most commonly after cataract removal but can be used for purely refractive purposes. Prescription of corrective lenses Corrective lenses are typically prescribed by an ophthalmologist or an optometrist. The prescription consists of all the specifications necessary to make the lens. Prescriptions typically include the power specifications of each lens (for each eye). Strengths are generally prescribed in quarter-diopter steps (0.25 D) because most people cannot generally distinguish between smaller increments (e.g., eighth-diopter steps / 0.125 D). The use ...
