Article: Yerevan Vernissage (arts and crafts market), close to Republic Square, bustles with hundreds of vendors selling a variety of crafts on weekends and Wednesdays (though the selection is much reduced mid-week). The market offers woodcarving, antiques, fine lace, and the hand-knotted wool carpets and kilims that are a Caucasus specialty. Obsidian, which is found locally, is crafted into assortment of jewellery and ornamental objects. Armenian gold smithery enjoys a long tradition, populating one corner of the market with a selection of gold items. Soviet relics and souvenirs of recent Russian manufacture – nesting dolls, watches, enamel boxes and so on – are also available at the Vernisage.

Question: What are some examples of soviet memorabilia that can be purchased at Vernissage?
Ans: nesting dolls, watches, enamel boxes


Article: Thomas J. Watson, Sr., fired from the National Cash Register Company by John Henry Patterson, called on Flint and, in 1914, was offered CTR. Watson joined CTR as General Manager then, 11 months later, was made President when court cases relating to his time at NCR were resolved. Having learned Patterson's pioneering business practices, Watson proceeded to put the stamp of NCR onto CTR's companies. He implemented sales conventions, "generous sales incentives, a focus on customer service, an insistence on well-groomed, dark-suited salesmen and had an evangelical fervor for instilling company pride and loyalty in every worker". His favorite slogan, "THINK", became a mantra for each company's employees. During Watson's first four years, revenues more than doubled to $9 million and the company's operations expanded to Europe, South America, Asia and Australia. "Watson had never liked the clumsy hyphenated title of the CTR" and chose to replace it with the more expansive title "International Business Machines". First as a name for a 1917 Canadian subsidiary, then as a line in advertisements. For example, the McClures magazine, v53, May 1921, has a full page ad with, at the bottom:

Question: In what year did Thomas J. Watson, Sr. join CTR?
Ans: 1914


Article: Some writers claim the Air Staff ignored a critical lesson, however: British morale did not break. Targeting German morale, as Bomber Command would do, was no more successful. Aviation strategists dispute that morale was ever a major consideration for Bomber Command. Throughout 1933–39 none of the 16 Western Air Plans drafted mentioned morale as a target. The first three directives in 1940 did not mention civilian populations or morale in any way. Morale was not mentioned until the ninth wartime directive on 21 September 1940. The 10th directive in October 1940 mentioned morale by name. However, industrial cities were only to be targeted if weather denied strikes on Bomber Command's main concern, oil.

Question: Aviation strategists disputed over what? 
Ans: that morale was ever a major consideration for Bomber Command.


Article: In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.

Question: A vacuum state with no matter particles or photons is called what?
Ans:
QED
