The History of the Grand Coulee Dam (documentary)
The world's largest concrete dam--and the second largest concrete structure in the world--lies on the Columbia River in the State of Washington. It is also one of the largest hydroelectric power plants in the world, and it's huge irrigation pumps are big enough to pump dry most of the rivers in the United States. It's construction in an isolated and thinly populated area of the U.S. during the Depression years, was one of the greatest achievements of the Work Projects Administration, President Franklin Roosevelt's bid to restore prosperity and jobs to a nation in trouble. Constructed by Mason-Walsh-Atkinson-Kier Co. in 1931, it is 550 feet high and 4,173 feet in length.

Grand Coulee Dam is a concrete gravity dam on the Columbia River in the U.S. state of Washington, built to produce hydroelectric power and provide irrigation water. Constructed between 1933 and 1942, Grand Coulee originally had only two powerhouses. The third powerhouse, completed in 1974 to increase energy production, makes Grand Coulee the largest power station in the United States by nameplate-capacity at 6,809 MW.
The Case of the White Kitten / Portrait of London / Star Boy
London is the capital city of England and the United Kingdom, the largest city, urban zone and metropolitan area in the United Kingdom, and the European Union by most measures.[note 1] Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium.[3] London's ancient core, the City of London, largely retains its square-mile mediaeval boundaries. Since at least the 19th century, the name London has also referred to the metropolis developed around this core.[4] The bulk of this conurbation forms the London region[5] and the Greater London administrative area,[6][note 2] governed by the elected Mayor of London and the London Assembly.[7]
London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence.[8] It is the world's leading financial centre alongside New York City[9][10][11] and has the fifth- or sixth-largest metropolitan area GDP in the world depending on measurement.[note 3][12][13] London has been described as a world cultural capital.[14][15][16][17] It is the world's most-visited city measured by international arrivals[18] and has the world's largest city airport system measured by passenger traffic.[19] London's 43 universities form the largest concentration of higher education in Europe.[20] In 2012, London became the first city to host the modern Summer Olympic Games three times.[21]
London has a diverse range of peoples and cultures, and more than 300 languages are spoken within its boundaries.[22] In March 2011, London had an official population of 8,174,100, making it the most populous municipality in the European Union,[23][24] and accounting for 12.5% of the UK population.[25] The Greater London Urban Area is the second-largest in the EU with a population of 8,278,251,[26] while the London metropolitan area is the largest in the EU with an estimated total population of between 12 million[27] and 14 million.[28] London had the largest population of any city in the world from around 1831 to 1925.[29]. The latest census reveals white Britons as minority in London for first time in modern times. [30] London contains four World Heritage Sites: the Tower of London; Kew Gardens; the site comprising the Palace of Westminster, Westminster Abbey, and St Margaret's Church; and the historic settlement of Greenwich (in which the Royal Observatory marks the Prime Meridian, 0° longitude, and GMT).[31] Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Paul's Cathedral, Tower Bridge, Trafalgar Square, and The Shard. London is home to numerous museums, galleries, libraries, sporting events and other cultural institutions, including the British Museum, National Gallery, Tate Modern, British Library, Wimbledon, and 40 West End theatres.[32] The London Underground is the oldest underground railway network in the world and will complete 150 years of operations on 9 January 2013.[33][34]
Words at War: Mother America / Log Book / The Ninth Commandment
On 1 September 1939, Germany and Slovakia—a client state in 1939—attacked Poland.[46] On 3 September France and Britain, followed by the countries of the Commonwealth,[47] declared war on Germany but provided little support to Poland other than a small French attack into the Saarland.[48] Britain and France also began a naval blockade of Germany on 3 September which aimed to damage the country's economy and war effort.[49][50]
On 17 September, after signing a cease-fire with Japan, the Soviets also invaded Poland.[51] Poland's territory was divided between Germany and the Soviet Union, with Lithuania and Slovakia also receiving small shares. The Poles did not surrender; they established a Polish Underground State and an underground Home Army, and continued to fight with the Allies on all fronts outside Poland.[52]
About 100,000 Polish military personnel were evacuated to Romania and the Baltic countries; many of these soldiers later fought against the Germans in other theatres of the war.[53] Poland's Enigma codebreakers were also evacuated to France.[54] During this time, Japan launched its first attack against Changsha, a strategically important Chinese city, but was repulsed by late September.[55]
Following the invasion of Poland and a German-Soviet treaty governing Lithuania, the Soviet Union forced the Baltic countries to allow it to station Soviet troops in their countries under pacts of mutual assistance.[56][57][58] Finland rejected territorial demands and was invaded by the Soviet Union in November 1939.[59] The resulting conflict ended in March 1940 with Finnish concessions.[60] France and the United Kingdom, treating the Soviet attack on Finland as tantamount to entering the war on the side of the Germans, responded to the Soviet invasion by supporting the USSR's expulsion from the League of Nations.[58]
In Western Europe, British troops deployed to the Continent, but in a phase nicknamed the Phoney War by the British and Sitzkrieg (sitting war) by the Germans, neither side launched major operations against the other until April 1940.[61] The Soviet Union and Germany entered a trade pact in February 1940, pursuant to which the Soviets received German military and industrial equipment in exchange for supplying raw materials to Germany to help circumvent the Allied blockade.[62]
In April 1940, Germany invaded Denmark and Norway to secure shipments of iron ore from Sweden, which the Allies were about to disrupt.[63] Denmark immediately capitulated, and despite Allied support, Norway was conquered within two months.[64] In May 1940 Britain invaded Iceland to preempt a possible German invasion of the island.[65] British discontent over the Norwegian campaign led to the replacement of Prime Minister Neville Chamberlain with Winston Churchill on 10 May 1940.[66]
