A.S. Douglas
Alexander Shafto "Sandy" Douglas CBE (21 May 1921 – 29 April 2010) was a British professor of computer science, credited with creating the first graphical computer game OXO, a Noughts and Crosses computer game in 1952 on the EDSAC computer at University of Cambridge. Biography Early life Douglas was born on 21 May 1921 in London. At age eight, his family moved to Cromwell Road, near what would become the London Air Terminal. A 74 bus ride for one old penny took me to Exhibition Road, from which I could go towards South Kensington station to my father's office (which is still there) and workshop (now demolished) down by what became the Lycée Français. Alternatively, I could turn north to the Science Museum – a trip I took often. In the winter of 1938–39, Douglas and his future wife Andrey Parker made a snowman in the grounds of the Natural History Museum. Douglas and his wife would go on to have two children and at least two grandsons. During the Blitz, in 1940� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to practical disciplines (including the design and implementation of hardware and software). Computer science is generally considered an area of academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing security vulnerabilities. Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of repositories o ...

Second Lieutenant
Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank. Australia The rank of second lieutenant existed in the military forces of the Australian colonies and Australian Army until 1986. In the colonial forces, which closely followed the practices of the British military, the rank of second lieutenant began to replace ranks such as ensign and cornet from 1871. New appointments to the rank of second lieutenant ceased in the regular army in 1986. Immediately prior to this change, the rank had been effectively reserved for new graduates from the Officer Cadet School, Portsea which closed in 1985. (Graduates of the Australian Defence Force Academy (ADFA) and the Royal Military College, Duntroon (RMC-D) are commissioned as lieutenants.). The rank of second lieutenant is only appointed to officers in special appointments such as training institutions, university regiments and while under probation during training. ...

Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system. ...

Universities Central Council On Admissions
Universities Central Council on Admissions (UCCA) provided a clearing house for university applications in the United Kingdom from its formation in 1961 until its merger with PCAS (Polytechnics Central Admissions System) to form UCAS in 1993. History UCCA was created in response to concerns during the 1950s that the increase in university applications was unmanageable using the systems then in place, where each student applied individually to as many institutions as they chose. This concern led to the Committee of Vice Chancellors and Principals ( CVCP) setting up an ad-hoc committee in 1957 to review the matter; this committee in its Third Report of January 1961 recommended the setting up of a central agency, which subsequently became known as UCCA. Its First and Second Reports had already made a number of recommendations aimed at harmonising admissions procedures across different universities. The name UCCA referred originally to the management board (the Central Council) over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leslie Ronald Kay
Ronald Kay (4 March 1920 – 17 May 2019) was a British University administrator who was instrumental in establishing the Universities Central Council on Admissions, and who was its chief executive until his retirement in 1985. Early life and career Ronald Kay was born in Sheffield. His father Ernest (1895-1973) was a cutler who had left school at 13 to work for the firm of George Wostenholm, where he slowly rose through the ranks to achieve the position of sales manager. His mother May (née Friskney) (1898-1946) was originally from Leicester; she taught piano. Ronald was the elder of two children; his sister Shirley (1928-1986) was nearly nine years younger. Ronald gained a scholarship to King Edward VII Grammar School, and subsequently an Edgar Allen scholarship to Sheffield University, where he read English. Graduating in 1941, he was disqualified from active service as a result of poor eyesight, and instead went to London to work for the Ministry of Shipping where ...

Pegasus (computer)
Pegasus was an early British vacuum-tube (valve) computer built by Ferranti, Ltd that pioneered design features to make life easier for both engineers and programmers. Originally it was named the Ferranti Package Computer as its hardware design followed that of the Elliott 401 with modular plug-in packages. Much of the development was the product of three men: W. S. (Bill) Elliott (hardware); Christopher Strachey (software) and Bernard Swann (marketing and customer support). It was Ferranti's most popular valve computer with 38 being sold. The first Pegasus was delivered in 1956 and the last was delivered in 1959. Ferranti received funding for the development from the National Research Development Corporation (NRDC). At least two Pegasus machines survive, one in The Science Museum, London and one which was displayed in the Science and Industry Museum, Manchester but which has now been removed to the storage in the Science Museum archives at Wroughton. The Pegasus i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Manchester Baby
The Manchester Baby, also called the Small-Scale Experimental Machine (SSEM), was the first electronic stored-program computer. It was built at the University of Manchester by Frederic C. Williams, Tom Kilburn, and Geoff Tootill, and ran its first program on 21 June 1948. The Baby was not intended to be a practical computing engine, but was instead designed as a testbed for the Williams tube, the first truly random-access memory. Described as "small and primitive" 50 years after its creation, it was the first working machine to contain all the elements essential to a modern electronic digital computer. As soon as the Baby had demonstrated the feasibility of its design, a project was initiated at the university to develop it into a full scale operational machine, the . The Mark 1 in turn quickly became the prototype for the Ferranti Mark 1, the world's first commercially available general-purpose computer. The Baby had a 32- bit word length and a memory of 32 words (1 k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stored-program Computer
A stored-program computer is a computer that stores program instructions in electronically or optically accessible memory. This contrasts with systems that stored the program instructions with plugboards or similar mechanisms. The definition is often extended with the requirement that the treatment of programs and data in memory be interchangeable or uniform. Description In principle, stored-program computers have been designed with various architectural characteristics. A computer with a von Neumann architecture stores program data and instruction data in the same memory, while a computer with a Harvard architecture has separate memories for storing program and data. However, the term ''stored-program computer'' is sometimes used as a synonym for the von Neumann architecture. Jack Copeland considers that it is "historically inappropriate, to refer to electronic stored-program digital computers as 'von Neumann machines'". Hennessy and Patterson wrote that the early Harvard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
