James Arthur Pollock
James Arthur Pollock, FRS, (17 November 1865 – 24 May 1922) was an Irish-born physicist, active in Australia. Born in Douglas, County Cork, Ireland and educated in England, in 1885 Pollock moved to Australia followed with by his family. In 1886, he was appointed second astronomical assistant to the New South Wales government astronomer, Henry Chamberlain Russell. In 1889 Pollock became professor of physics at the University of Sydney. He studied atmospheric ions and vacuum technology amongst other areas. In World War I, Pollock enlisted in the Engineering Corps and served with Edgeworth David. Pollock designed apparatus for use in tunnelling. This enabled destruction of German fortifications on the Messines and Wytschaete ridges in Belgium. He finished the war with the rank of major. Pollock died in Sydney, he had no children. He was buried in Waverley Cemetery The Waverley Cemetery is a heritage-listed cemetery on top of the cliffs at Bronte in the eastern suburbs of S ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ...

Waverley Cemetery
The Waverley Cemetery is a heritage-listed cemetery on top of the cliffs at Bronte in the eastern suburbs of Sydney, New South Wales, Australia. Opened in 1877 and built by R. Watkins (cemetery lodge, 1878) and P. Beddie (cemetery office, 1915), the cemetery is noted for its largely intact Victorian and Edwardian monuments. It is regularly cited as being one of the most beautiful cemeteries in the world. The cemetery contains the graves of many significant Australians including the poet Henry Lawson. Also known as General Cemetery Waverley, it was added to the New South Wales State Heritage Register on 28 October 2016. The cemetery is owned by Waverley Council and is self-funded, deriving its income from interments – including burial, cremation, memorials and mausolea – of which there has been over 86,000. Waverley Cemetery was used during the filming of the 1979 Mel Gibson film '' Tim'' and in 2021 the film '' Long Story Short''. The cemetery was designed to function alo ...

Battle Of Messines (1917)
The Battle of Messines (7–14 June 1917) was an attack by the British Second Army (General Sir Herbert Plumer), on the Western Front, near the village of Messines (now Mesen) in West Flanders, Belgium, during the First World War. The Nivelle Offensive in April and May had failed to achieve its more grandiose aims, had led to the 1917 French Army mutinies, demoralisation of French troops and confounded the Anglo-French strategy for 1917. The attack forced the Germans to move reserves to Flanders from the Arras and Aisne fronts, relieving pressure on the French. The British tactical objective was to capture the German defences on the ridge, which ran from Ploegsteert Wood (Plugstreet to the British) in the south, through Messines and Wytschaete to Mt Sorrel, depriving the German 4th Army (German Empire), 4th Army of the high ground. The ridge gave commanding views of the British defences and back areas of Ypres to the north, from which the British intended to conduct the North ...

Edgeworth David
Sir Tannatt William Edgeworth David (28 January 1858 – 28 August 1934) was a Welsh Australian geologist and Antarctic explorer. A household name in his lifetime, David's most significant achievements were discovering the major Hunter Valley coalfield in New South Wales and leading the first expedition to reach the South Magnetic Pole. He also served with distinction in World War I. Early life David was born on 28 January 1858, in St. Fagans near Cardiff, Wales, the eldest son of the Rev. William David, a fellow of Jesus College, Oxford, a classical scholar and naturalist and his wife Margaret Harriette (née Thomson). His mother's cousin, William A. E. Ussher of the Geological Survey, first interested David in what was to be his life work. At the age of 12, David went to Magdalen College School, Oxford in 1870. In 1876 he gained a classical scholarship to New College, Oxford. While there he was lectured by the famous John Ruskin and William Spooner. In 1878 he suff ...

Vacuum
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But hig ...
