H. J. R. Murray

Harold James Ruthven Murray was an English educationalist, inspector of schools, prominent chess historian. His book, A History of Chess, is regarded as the most authoritative and most comprehensive history of the game. Murray, the eldest of eleven children, was born near Peckham Rye in London; the son of Sir James Murray, the first editor of the Oxford English Dictionary, he attended school at Mill Hill and during his spare time helped his father produce the first edition of the OED. By the time Harold had finished school and was preparing to leave for university, he had been responsible for over 27,000 quotations that appeared in the OED, he won a place at Balliol College, Oxford where in 1890 he graduated with a first class degree in Mathematics. He became an assistant master at Taunton where he learned to play chess, he was assistant master at Carlisle Grammar School and in 1896 he became headmaster of Ormskirk Grammar School in Lancashire. On 4 January 1897 he married Miss Kate Maitland Crosthwaite.

In 1901, he was appointed a school inspector and in 1928 he became a member of the Board of Education. Murray was a champion of the left-handed, defending children against the attempts of schools to make them conform by using their right hand. In 1897 he was encouraged by Baron von der Lasa to research into the further past of chess. Murray gained access to the largest chess library in the world, that of John G. White of Cleveland and used the collection of J. W. Rimington Wilson in England; the White collection contained some Arabic manuscripts, so Murray learnt Arabic and examined many historical chess documents. The research took him 13 years, he contributed articles on aspects of chess history to the British Chess Magazine and the Deutsches Wochenschach in this time. In 1913 he published his most significant work, A History of Chess, proposing the theory that chess originated in India; this remains the most accepted theory today. In 1952 Murray published A History of Board Games other than Chess.

Although A History of Chess was recognised as the standard reference on the subject, its scholarly approach and great length made it inaccessible to most chess players. Murray began a shorter work on chess history written in a more popular style. Although begun many years earlier this work was unfinished at his death, it was completed by B. Goulding Brown and Harry Golombek and published in 1963 as A Short History of Chess. Murray was the father of the archaeologist Kenneth Murray.

Process network synthesis

Process network synthesis is a method to represent a process structure in a'directed bipartite graph'. Process network synthesis uses the P-graph method to create a process structure; the scientific aim of this method is to find optimum structures. Process network synthesis uses a bipartite graph method P-graph and employs combinatorial rules to find all feasible network solutions and links raw materials to desired products related to the given problem. With a branch and bound optimisation routine and by defining the target value an optimum structure can be generated that optimises a chosen target function. Process Network Synthesis was developed to solve chemical process engineering processes. Target value as well as the structure can be changed depending on the field of application, thus many more fields of application followed. At Pannon University software the tools PNS Editor and PNS Studio were programmed to generate maximum structure of processes; this software includes the p-graph method and MSG, SSG and ABB branch and bound algorithms to detect optimum structures within the maximum available process flows.

PNS is used in different applications where it can be used to find optimum process structures like: Process engineering: Chemical process designs and the Synthesis of chemical processes is applied in different case studies. Optimum energy technology networks for regional and urban energy systems: In case of regional and urban energy planning the financially most feasible solution for resource systems is selected as target value. With this setting material- and energy flows, energy demand and cost of technologies are considered and the optimum technology network can be found; the robustness of technologies due to price changes and limitations in resource availability can be identified. Evacuation routes in buildings: The aim is to find optimal routes to evacuate buildings depending on specific side parameters. Transportation routes: In this research area transportation routes with minimum cost and lowest environmental impact can be identified. P-Graph wiki P-graph method

Seven Mile Beach, Grand Cayman

Seven Mile Beach is a long crescent of coral-sand beach on the western end of Grand Cayman island. Seven Mile Beach is known for its beauty receiving the honor of "The Caribbean's Best Beach" from Caribbean Travel and Life Magazine, it is public property and one is able to walk the full length of the beach, regardless of where you are staying. The Seven Mile Beach is the most developed area of Grand Cayman, it is home to the majority of the island's luxury hotels. Despite the name, a generous measurement puts the actual length at just a bit over 6.3 miles long. A realistic length for the uninterrupted sandy beach is about 6 miles; the beach falls victim to annual erosion, which has reduced its size in some areas, may have reduced its length at the ends. Like the rest of Grand Cayman, the development around the Seven Mile Beach was damaged in Hurricane Ivan in September 2004 but many condominiums & hotels are still running at full capacity. Restaurants open to the public can be found at most of the resorts, which includes several public beach bars.

Some small reefs are located just off shore which offer good snorkelling, most notably by the Marriott hotel, Government House, just north of Seven Mile Public beach. Directly to the south of Seven Mile Beach is George Town, the capital city of the Cayman Islands and where the tourists come in, while to the north is the district of West Bay, which features a turtle farm and the limestone formations of Hell

George Forsythe

George Elmer Forsythe was the founder and head of Stanford University's Computer Science Department. George came to Stanford in the Mathematics Department in 1959, served as professor and chairman of the Computer Science department from 1965 until his death. Forsythe served as the president of the Association for Computing Machinery, co-authored four books on computer science and a fifth on meteorology, edited more than 75 other books on computer science. Forsythe married Alexandra I. Forsythe, who wrote the first published textbook in computer science and participated in her husband's work, while promoting a more active role for women than was common at the time. Between 1950 and 1958 both of them programmed using the SWAC at the National Bureau of Standards in Los Angeles and at UCLA after the western division of NBS was closed due to political pressures. With his wife, Forsythe had a son. According to Donald Knuth, Forsythe's greatest contributions were helping to establish computer science as its own academic discipline and starting the field of refereeing and editing algorithms as scholarly work.

Professor Forsythe supervised 17 PhD graduates. He won a Lester R. Ford Award in 1969 and again in 1971.

Jeffrey Batters Home-Hay

Captain Jeffery Batters Home-Hay was a Scottish-born Canadian who became a flying ace during World War I. He was a bomber pilot, he was shot down and captured toward the end of World War I. After being repatriated, he became a pioneering Canadian bush pilot. By the end of his aviation career, he was the oldest pilot still flying in Canada. Jeffrey Batters Home-Hay was born in Alloa, Scotland on 2 February 1887, he was schooled in Scotland until 1904. He apparently served in the military in the Argyll and Sutherland Highlanders Regiment, as he was commissioned into it later, he was orphaned in his youth, emigrated with his widowed mother and his five siblings from Scotland to Canada prior to World War I, in 1908. He farmed at Saskatchewan, he enlisted into the 32nd Battalion, CEF at Winnipeg, Saskatchewan on 29 December 1914 as a private, with the regimental number 81404. On his enlistment attestation paper, he gave his residence as Kamsack, his occupation as steam fitter, claimed prior military experience.

His next of kin listing of his mother, Margaret Batters Home-Hay as residing in Alloa, indicates she had re-emigrated. The enlistee's physical stated. Although Home-Hay was assigned to the Machine Gun Section of the 32nd Battalion, he served in France with the 2nd Battalion from April to December 1915. Towards the end of this duty, he was appointed a second lieutenant in the Argyll and Sutherland Highlanders effective 23 November 1915, with pay and allowances to begin 6 January 1916, he transferred to the Royal Flying Corps, reporting on 16 May 1916 to Reading, England for aviation training. He was posted to No. 14 Squadron RFC on 19 June 1916 to No. 6 Squadron RFC. On 10 July 1916, he was awarded Royal Aero Club Aviators Certificate number 3209, he underwent advanced training at Catterick Aerodrome. On 30 July 1916, he was appointed as a flying officer in the Royal Flying Corps and seconded for aviation duty; when he was posted to No. 53 Squadron RFC in August 1916, it was still in England. He moved with it to France in early 1917 to fly artillery cooperation duty, for which he won a Military Cross.

The accompanying award citation read: "He showed consistent ability and courage in observing for and ranging our artillery upon enemy guns, trenches. His accurate Information was of the greatest value to our batteries."He was appointed a flight commander in the Royal Flying Corps on 7 June 1917, with an accompanying promotion to the rank of temporary captain. On 1 July 1917, he was promoted to the rank of lieutenant in his home regiment, the Argylls, but remained seconded to the RFC, he served with the RFC until returned to Home Establishment in England on 15 December 1917. Home-Hay was assigned to No. 105 Squadron RFC on 4 January 1918. On 19 May 1918, he joined the Independent Air Force's No. 104 Squadron RAF at France. He flew strategic bombing raids into Germany, he and his observer were taken prisoner. Home-Hay won a Distinguished Flying Cross, gazetted on 21 September 1918, his award citation noted: "This officer displayed admirable coolness and resource while leading a raid on an enemy railway station.

His formation was attacked by seven aeroplanes, but keeping it well in hand, he fought his way to his objective. In the course of the severe fighting two hostile machines were shot down out of control, one of which he himself brought down, he has taken part in eight other raids, his consistent gallantry is a valuable asset in maintaining the morale of his new squadron."Unmentioned in this citation is an instance of gallantry, noted in the letter of recommendation for the award: "While the encounter with enemy aeroplanes was in progress at 14,000 feet over the objective, Captain J. B. Home-Hay saw a machine of another squadron which had lost its formation and was at a low altitude firing Very lights for assistance as it was being attacked. Captain Home-Hay brought his formation down to 9,000 feet and picked this machine up in his formation, escorted it to the lines."Home-Hay's pilot's log was lost during his confinement by the Germans, but he estimated that by war's end he had over 1,500 hours flight time in two-seater aircraft.

Types flown included not just DH.9s, but Maurice Farmans, Royal Aircraft Factory RE.8s, Airco DH.4s. Home-Hay was repatriated from being a POW in mid December 1918, he was belatedly Mentioned in Despatches on 1 January 1919 because after No. 99 Squadron RAF lost seven out of nine planes on 31 July 1918 while bombing Saarbrücken, Home-Hay helped lead a successful follow-up attack. On 22 August, on the sortie on which he was shot down, Home-Hay helped lead an attack on Mannheim, Germany despite being attacked by ten German fighters. After his return from captivity, he was assigned to schools to temporary command of No. 106 Squadron RAF, until he was shipped home to Canada from RAF Upavon on 10 June 1919. On 18 July 1919, he went on the unemployed list of the Royal Air Force. On 7 April 1920, he asked to join the nascent Canadian Air Force. Meanwhile, he was farming in Canada when asked to take part in the first Canadian transcontinental flight from Halifax, Nova Scotia to Vancouver in late August 1920.

Despite official miscommunications via mail, a break from flight preparations necessitated by a brother's severe illness at harvest time, Home-Hay helped prepare planes for the flight and took part in the historic journey, returning to his
