In the intervening years, airborne radar has become one of the most important branches of civilian and military radar.Jag forstar. In the 1950s and 1960s he made discoveries based on radio observations of the Sun. In the late 1960s and early 1970s his team built and operated the world's first solar radio-spectrographs and subsequently the Culgoora radio-heliograph, near Narrabri, New South Wales. The Paul Wild Observatory at Culgoora is named after him.From 1978 to 1985 he was chairman of the CSIRO, during which time he expanded the organisation's scope and directed its restructuring. He retired from the CSIRO to lead (from 1986) the Very Fast Train Joint Venture, a private sector project that sought to build a high-speed railway between Australia's two most populous cities. Lack of support from government brought it to an end in 1991. In his later years he worked on gravitational theory.But in that year, Alwyn's business collapsed and he went to the United States of America to sell his patents and technology for cutlery manufacture. In the event, he never returned. Bessie moved with her boys to Croydon, near London.However, after a year of mathematics he knew that he would only be able to stay on if he did something relevant to the national war effort. He said the great majority of people in Part 2 Physics had already done two years of it before, so it was a real challenge.https://www.tai.gr/wp-content/plugins/formcraft/file-upload/server/content/files/16297adcb4e1eb---computer-hardware-troubleshooting-manual.pdf It was hard work, it was six days a week.A wartime Bachelor of Arts degree was conferred a year later. A few years afterwards he paid five pounds to become a Master of Arts.In July 1943, commissioned as a Probationary Temporary Acting Sub-lieutenant (Special Branch, Royal Navy Volunteer Reserve ), he started an intensive, six-month radar officer training course at the Royal Navy base, Portsmouth. The ship took part in the Okinawa campaign, followed by the assault on the Japanese mainland. In both campaigns the fleet was frequently attacked by Japanese suicide bombers, but because they tended to concentrate on aircraft carriers, his ship was not hit.During one of his wartime breaks in Australia he had become engaged to a young Sydney woman, Elaine Hull, whose family had offered hospitality; and on leaving the Royal Navy he immediately sailed for Sydney. He had asked his fiancee to go to England to be married, but she told him he would have to settle in Australia.He was a wonderfully inspiring leader, very self-effacing and taking no credit for himself, and he was a delight to work under.He chose to work for Lindsay McCready in building a radiospectrograph, at the suggestion of Pawsey. At Penrith, 50 kilometres west of Sydney in the foothills of the Blue Mountains, a fairly primitive wooden aerial was pulled around with ropes, and every twenty minutes it was changed so that it pointed towards the Sun. The data were analysed after four months of observations.In September 1950, he and three colleagues borrowed a decrepit ex-military ambulance and with a spectrum analyser assessed potential sites on the outskirts of Sydney and down the New South Wales south coast that would be least affected by interference from radio transmissions.Sheridan's hand is on a very early fax machine, borrowed from a newspaper publisher. Wild likened this research to the study of taxonomy that preceded Darwin's Origin of species.fashionedits.com/upload/ckupload/files/Cannon-kendal-c60ekk-manual.pdfIt was to become a ground-breaking instrument producing real-time images of solar activity across a range of altitudes from the Sun's surface.Wild wanted to actually see what these phenomena looked like on the Sun, actually get a moving picture of them. The frequency range that we were interested in was around about the metre wavelengths. To get the resolution roughly equivalent to that of the human eye at these long wavelengths required an aperture some three kilometres in diameter.Wild published more than 70 papers in this field. It was de-commissioned in 1984 to make way for the Australia Telescope and transferred to the Ionospheric Prediction Service, where it is still used today for space weather monitoring of solar activity.During a period when the solar cycle was at a minimum and nothing was happening, Rowe drove down to Dapto for an 11 am appointment. Wild remarked: Out of sheer conscientiousness he arrived at 8 am, switched on the gear and recorded the most magnificent outburst, which led to the discovery of first and second harmonics.With George Gamow and instigator Harry Messel, he was a member of the inaugural trio who, from 1962, brought high-level science teaching to senior secondary students throughout Australia.Some installations became operational in the 1990s and more were set up subsequently in Europe. NASA has operated a similar system to land space shuttles. However, Interscan has not become widely deployed worldwide, largely because the US Federal Aviation Administration has developed the Wide Area Augmentation System (WAAS), which augments the satellite-based Global Positioning System (GPS). Although WAAS is cheaper and conforms to ILS Category I, its accuracy is under 1.0 metre laterally and under 1.5 metres vertically, which is a particular concern at locations that frequently suffer from low visibility.I had a strong desire always to see pure and applied research undertaken side by side in the same laboratory.https://www.festivalmarrakech.info/wp-content/plugins/formcraft/file-upload/server/content/files/16297adcb51e42---Computer-installation-manual.pdf I felt that fundamental research in the end was going to reap the real benefits in the long run.In October that year, he decided to take it from Canberra to a CSIRO meeting in Sydney.I was absolutely appalled by the whole thing. After I flew home that night, I looked up an old reference book.But despite the cordiality, it became apparent that such a project was unlikely to go far under the umbrella of the SRA. Eventually he fixed on the notion of completing the journey in three hours, which would be highly competitive with air travel.On the day before Good Friday, they agreed on the components and who would write them. They all had commitments and agreed it would take six weeks to put a draft together. However, such was their private enthusiasm that each of them worked right through the four-day break, virtually finishing their drafts. This route was chosen because it would provide better access for people in the coastal south-east of New South Wales and eastern Victoria, who were very poorly served by transport links.A meeting with the department secretary and senior officers of his department and the Bureau of Transport Economics was to foreshadow an uneasy relationship that was to continue despite the ostensibly cooperative attitude of federal and state governments. The proposal had been sent to the federal Minister for Transport, Peter Morris, with comments reflecting his officials' opinion: it was not worth considering.On 12 September 1984, answering a Question without Notice in the House of Representatives, he described the proposal as grandiose, likening it to another proposal to build a canal through the centre of Australia.He called for a much larger, objective investigation by independent experts, including those from overseas countries which already had fast trains.By September 1986 he had brought together an unincorporated joint venture of TNT, Elders IXL and Kumagai Gumi.https://www.magicapro.it/wp-content/plugins/formcraft/file-upload/server/content/files/16297addb8e953---computer-hardware-maintenance-manual-pdf.pdf In August 1987, after delay caused by uncertainties surrounding a potential takeover of their company, the BHP joined as the fourth, and subsequently foremost, partner.It postulated that the project was technically feasible and financially viable.In December, a VFT Concept Report was released, identifying the key issues for a high-speed rail system, to be built and operated by private enterprise, with trains operating between Sydney, Canberra and Melbourne at speeds up to 350 km per hour.A survey of Gippsland residents found it had 70 support. A Morgan research poll found 65 support for the project throughout Victoria and New South Wales.In October 1990, Wild announced that the inland route was the preferred choice for the VFT. The decision not to proceed with the original route to the east of the Snowy Mountains and through Gippsland was a difficult one for the VFT Joint Venture and for Wild personally.Aware of the growth that fast trains overseas had generated along entire routes, he could not see the point of going inland, where few people wanted to live.They had differing agendas and a tendency to look for problems associated with the project rather than the opportunities it offered. This attitude led to the eventual insurmountable hurdle which the project faced, when the issue arose of the tax treatment which would be necessary for the project to proceed. The VFT team worked hard in 1990 and 1991 to devise an acceptable approach.Ironically, the federal government soon introduced infrastructure bonds to assist major projects facing the same financial hurdles as the VFT.If the VFT project had advanced reasonably quickly, Australia would have been about the sixth country in the world to have high-speed rail, after Germany and Spain. Today, high speed rail services are operating in a dozen countries, and a similar number are building or planning them.contratacionestatal.com/aym_image/files/Cannon-k38-manual.pdfA few months later he proposed to his colleague's widow, Margaret Lyndon, and they had 12 happy years together before she died.The origin of inertia was a special interest Wild had, which they discussed at great length.In a 1995 interview Wild nominated his most significant achievement to be the building of the Culgoora radio-heliograph and providing the world with a unique eye to view and record moving pictures of rapidly changing solar activity. He observed: most scientific discoveries, had they not been made by the originator, would have been made by somebody else within a year or so or even less. Today, nearly three decades later, the instrument has not been duplicated and the results remain unique. In saying this I do not want to give the impression that I did it all by myself.It was evident from early days, such as in the Pacific, when the officers of HMS King George V entertained some American admirals and their staffs. It was, he related, I had one talent in those days, in the amusement line, and that was to give a convincing imitation of the Fuhrer and of Winston Churchill. And the captain grabbed me and said he wanted me to address them as Hitler. And so somebody got a burnt cork and produced the moustache and a comb on the hair, and there they were assembled before me, all this mass of gold braid.His formative naval service gave him a strong sense of teamwork and obligation to others, and to seeking the fairest way ahead.Australian astronomers: achievements at the frontiers of astronomy.

Scientists from the Council for Scientific and Industrial Research (CSIR, later CSIRO), supported by the Royal Australian Air Force (RAAF), began a program to observe radio waves emitted from the Sun using equipment which had been installed at the Collaroy Plateau air and sea defence radar station during WWII. The detection on 3 October of intense radio emission coming from the Sun marked the birth of radio astronomy in Australia. Provided with this critical information, the Australian Government allocated 80,000 pounds for the CSIR to establish a radar research facility that would develop radar defence systems for Australia. For security purposes the Radiophysics Laboratory was co-located with the CSIR National Standards Laboratory in what is now the Madsen building in the grounds of the University of Sydney. The first CSIR staff moved into the new facility in March 1940. By the end of the war, the Division employed over 60 scientists and had developed more than 20 different types of radar systems. The CSIR became the Commonwealth Science and Industrial Research Organisation (CSIRO) in 1949. In many cases, the radar systems designed by the Division of Radiophysics were manufactured by the NSW Government Railways workshops. In pulse radar, the time taken to send and receive a reflected signal is used to determine the distance to the object. Radar can operate during day or night, through cloud, fog or rain. Following the Japanese air raid on Pearl Harbour on 7 December 1941, it was realised that Australia would also be vulnerable to air attack, so an urgent program to develop air warning radar was established. Australia’s vulnerability to air attack was demonstrated by the Japanese air raid on Darwin on 19 February 1942. The Radiophysics team quickly developed a modified prototype version based of the existing shore defence radar at Dover Heights. This was not only light-weight to allow air transportation, but also was designed so that its structure and electronics would function effectively in the humid tropical environment of the South-West Pacific Theatre of War. The Plateau is located approximately 10 kilometres north of the North Head entrance to Sydney Harbour and 60 kilometres east of the Blue Mountains. It is at a height of 110 m above sea level. The Collaroy Plateau station was one of the most critical stations for air warning for Sydney’s northern approaches. The site was officially decommissioned in February 1946 following the end of hostilities, and the equipment was ultimately removed from the site. This view is looking toward the east with the control room in the foreground. This radar was designed in Britain with the aerial and its tower built by the NSW Government railways. (Photo courtesy of Deidre and Jim Thorncraft, reproduced from Ted Dellit’s book The Royal Australian Air Force on Collaroy Plateau in the Second World War, 2000). The area occupied by the radar station is now occupied by the Northern Beaches Council’s community park, Plateau Park. The “yellow” boundary on the 1943 image shows the approximate boundary of the park today. The radar shown in Figure 2 is located toward the centre of the 1943 image ( ) Of particular interest was the report received from Dr Elizabeth Alexander, the Head of the Operational Research Section of the Radio Development Laboratory in New Zealand. In March 1945 she arranged for the Royal New Zealand Air Force at Norfolk Island to observe the Sun using radar receiver equipment and reported the reception of strong signals over a period of several days. These reports inspired the Division to begin a program of solar observations at radio wavelengths using radar equipment developed for defence. RAAF radar operators, on instruction from CSIR scientists led by the Group’s Head, Dr Joseph L Pawsey, used the 200 MHz COL RAAF radar shown in Figure 2 for observations. The radar aerial was mounted vertically and was rotated around a vertical axis to observe the Sun at sunrise and rotated to face the west to observe sunset. In this reception-only mode, the radar system was set to receive but not transmit signals.The RAAF operators captured the first Australian radio-frequency detection of the Sun and the first Australian radio astronomy observation. Ruby Payne-Scott ( Figure 5), who worked for Joseph Pawsey, recorded this description in her 1945 internal laboratory report: In successive sweeps this increase in noise became more marked, until at 0540 the noise power on a bearing of 93 degrees was four and a half times the normal noise power. Over the next twenty minutes it declined, rose again to a smaller peak at 0610 and then declined again, the effect being just detectable at 0730. Most of the readings were recorded for the team by the RAAF staff working at the site. Daily observations were taken for about an hour at sunrise, and again at sunset with the aerial directed west towards the Blue Mountains. This program, described by Payne-Scott in her 1945 internal report and by Pawsey, Payne-Scott and McCready ( Figure 6) in 1946 in a letter to the highly regarded scientific journal, Nature, was highly successful. The three CSIR scientists discovered some surprising characteristics of the Sun at the radio frequency of 200 MHz (a wavelength of 1.5 m), they include: By comparing the radio data with solar data provided from Mt Stromlo Solar Physics Observatory (Canberra), they found that the fluctuations were strongly correlated with sunspots on the Sun’s surface ( Figure 8). Pawsey, Payne-Scott and McCready (1946) wrote that The theorist David F. Martyn predicted that the Corona would produce thermal radiation observable at radio frequencies at these temperatures. Martyn’s predication, and Pawsey’s observations confirming the theory, appeared together in Nature on 2 November 1946. They were able to detect an enhanced level of diffuse radio emission coming from our Galaxy, particularly as the centre of our Milky Way galaxy rose above the eastern horizon. This very extended emission from the plane of our Galaxy was discovered by the American, Karl Jansky in 1932. As this original diagram is very faint, reconstructed plots are shown below. The two time-series plots show the maximum strength of the solar emission measured from observations taken at sunrise between October 1945 and March 1946. The vertical axis shows the detected radio power in decibels, where a level of 0 dB, corresponds to approximately the total flux density of the quiet Sun at 200 MHz. The measured output receiver power levels varied by up to 10 dB. The bottom histogram shows the number of observations for the observed range of power levels in 2 db steps. The level correlates with the number of sunspots visible on the Sun’s surface (middle plot). When there is a large number of spots covering a large area, the radio emission is stronger. The bottom diagram shows the position of sunspots on the Sun’s surface as viewed from Earth. These spots move postion as the Sun rotates. This diagram appeared in the scientific journal Nature in 1946 and was submitted on 23 October 1945, the same day as the last measurement on the graph. The equivalent temperature of the solar radio emission at 200 MHz was estimated to fluctuate between approximately one million and 12 million degrees. Pawsey and his team at the CSIR Division of Radiophysics went on to develop new instruments and techniques at Dover Heights and other field stations around Sydney.
