Toronto
Toronto ( ; or ) is the capital city of the Canadian province of Ontario. With a recorded population of 2,794,356 in 2021, it is the most populous city in Canada and the fourth most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. Toronto is an international centre of business, finance, arts, sports and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world. Indigenous peoples have travelled through and inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later designat ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry DeWolf Smyth
Henry DeWolf "Harry" Smyth (; May 1, 1898September 11, 1986) was an American physicist, diplomat, and bureaucrat. He played a number of key roles in the early development of Nuclear power, nuclear energy, as a participant in the Manhattan Project, a member of the U.S. Atomic Energy Commission (AEC), and U.S. ambassador to the International Atomic Energy Agency (IAEA). Educated at Princeton University and the University of Cambridge, he was a faculty member in Princeton's Department of Physics from 1924 to 1966. He chaired the department from 1935 to 1949.

British Army Of The Rhine
There have been two formations named British Army of the Rhine (BAOR). Both were originally occupation forces in Germany, one after the First World War and the other after the Second World War. Both formations had areas of responsibility located around the German section of the River Rhine. History 1919–1929 The first British Army of the Rhine was set up in March 1919 to implement the occupation of the Rhineland. It was originally composed of five corps, composed of two divisions each, plus a cavalry division: II Corps: Commanded by Sir Claud Jacob :* Light Division (formed from 2nd Division): Commanded by Major-General George Jeffreys :* Southern Division (formed from 29th Division): Commanded by Major-General William Heneker IV Corps: Commanded by Sir Alexander Godley :* Lowland Division (formed from 9th Division) :* Highland Division (formed from 62nd Division) VI Corps: Commanded by Sir Aylmer Haldane :* Northern Division (formed from 3rd Division) :* London Di ...

Hindenburg Line
The Hindenburg Line (German: , Siegfried Position) was a German defensive position built during the winter of 1916–1917 on the Western Front during the First World War. The line ran from Arras to Laffaux, near Soissons on the Aisne. In 1916, the Battle of Verdun and the Battle of the Somme left the German western armies () exhausted and on the Eastern Front, the Brusilov Offensive had inflicted huge losses on the Austro-Hungarian armies and forced the Germans to take over more of the front. The declaration of war by Romania had placed additional strain on the German army and war economy. The Hindenburg Line, built behind the Noyon Salient, was to replace the old front line as a precaution against a resumption of the Battle of the Somme in 1917. By wasting the intervening ground, the Germans could delay a spring offensive in 1917. A shortened front could be held with fewer troops and with tactical dispersal, reverse-slope positions, defence in depth and camouflage, Germ ...

Battle Of Passchendaele
The Third Battle of Ypres (german: link=no, Dritte Flandernschlacht; french: link=no, Troisième Bataille des Flandres; nl, Derde Slag om Ieper), also known as the Battle of Passchendaele (), was a campaign of the First World War, fought by the Allies against the German Empire. The battle took place on the Western Front, from July to November 1917, for control of the ridges south and east of the Belgian city of Ypres in West Flanders, as part of a strategy decided by the Allies at conferences in November 1916 and May 1917. Passchendaele lies on the last ridge east of Ypres, from Roulers (now Roeselare), a junction of the Bruges-(Brugge)-to-Kortrijk railway. The station at Roulers was on the main supply route of the German 4th Army. Once Passchendaele Ridge had been captured, the Allied advance was to continue to a line from Thourout (now Torhout) to Couckelaere (Koekelare). Further operations and a British supporting attack along the Belgian coast from Nieuport ( Nieuwpoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.. Trench warfare proliferated when a revolution in firepower was not matched by similar advances in mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front, protected from assault by barbed wire. The area between opposing trench lines (known as " no man's land") was fully exposed to artillery fire from both sides. Attacks, even if successful, often sustained severe casualties. The development of armoured ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Academic Term
An academic term (or simply term) is a portion of an academic year, the time during which an educational institution holds classes. The schedules adopted vary widely. In most countries, the academic year begins in late summer or early autumn and ends during the following spring or summer. In Northern Hemisphere countries, this means that the academic year lasts from August, September, or October to May, June, or July. In Southern Hemisphere countries, the academic year aligns with the calendar year, lasting from February or March to November or December. The summer may or may not be part of the term system. Synonyms ''Semester'', ''trimester'' and ''quarter'' are all synonyms for an academic term (the last two being mainly confined to American English), which refer to terms of specific periods as described below: *Semester ( la, sēmestris, lit=six monthly) originally German, where it referred to a university session of six months, adopted into American usage in the early 19th ...

Ice Hockey
Ice hockey (or simply hockey) is a team sport played on ice skates, usually on an ice skating rink with lines and markings specific to the sport. It belongs to a family of sports called hockey. In ice hockey, two opposing teams use ice hockey sticks to control, advance and shoot a closed, vulcanized, rubber disc called a " puck" into the other team's goal. Each goal is worth one point. The team which scores the most goals is declared the winner. In a formal game, each team has six skaters on the ice at a time, barring any penalties, one of whom is the goaltender. Ice hockey is a full contact sport. Ice hockey is one of the sports featured in the Winter Olympics while its premiere international amateur competition, the IIHF World Championships, are governed by the International Ice Hockey Federation (IIHF) for both men's and women's competitions. Ice hockey is also played as a professional sport. In North America as well as many European countries, the sport is known simply ...
