Isono Kazumasa (磯野 員昌 , 1534–1583) was relatively the most senior of retainer beneath the clan of Azai throughout the latter Sengoku Period of Feudal Japan.
 Initially at the time in which Kazumasa began his service under the Azai, Sukemasa was the present head over the clan, and Kazumasa began his great line of feats by supporting the former in a desperate conflict against the Rokkaku that took place in 1561.
 Within this event, the Rokkaku attempted to ultimately take over the entire Sawayama castle through means of besiegement, but were met with failure in this attempt after Kazumasa was sent as relief, convincing Sukemasa to allow this respective retainer complete jurisdiction over Sumamata castle as a reward for his reliability.
 Following the succession of Azai Nagamasa, Kazumasa willingly supported the former within many variable conflicts throughout the years that had passed, the most notable being Anegawa of 1570, where Kazumasa was said to have fought with such conviction and courage on the battlefield that his favorite horse was shot out beneath him and he unhesitatingly mounted a new horse immediately following the first, charging even deeper into the Oda ranks that surrounded him.
 In furthered justification to this, Kazumasa penetrated so far past the soldiers of Shibata Katsuie and Toyotomi Hideyoshi that he would have initially breached into the main camp of Oda Nobunaga if the additional units of Mori Yoshinari and Sakuma Nobumori did not immediately assist their respective allies.
Milton Friedman ( ; July 31, 1912 – November 16, 2006) was an American economist who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory, and the complexity of stabilization policy.
 With George Stigler and others, Friedman was among the intellectual leaders of the second generation of Chicago price theory, a methodological movement at the University of Chicago's Department of Economics, Law School, and Graduate School of Business from the 1940s onward.
 Several students and young professors that were recruited or mentored by Friedman at Chicago went on to become leading economists; they include Gary Becker, Robert Fogel, Thomas Sowell, and Robert Lucas, Jr.
The Nationality Law of the People's Republic of China regulates nationality of the People's Republic of China.
 Chinese nationality is usually obtained either by birth when at least one parent is of Chinese nationality or by naturalization.
Romani people (Czech: "Romové" , commonly known as Gypsies Czech: "Cikáni" ) in the Czech Republic constitute a minority.
 According to the last census from 2011, the Romani nationality was reported by the total of 13,150 inhabitants.
 Only a small part of them filled in only the Romani nationality (5 199).
 Most of them stated the Romani nationality in combination with another one, for example, the Romani and Czech, the Romani and Moravian and the like (7,951).
 In the 2001 Census, 11,746 people reported the Romani nationality – at that time it was 0.1% of those claiming some nationality.
 In 2011, the result 13,150 is 0.2% of those, who reported some nationality.
Edwin Hewitt (January 20, 1920, Everett, Washington – June 21, 1999) was an American mathematician known for his work in abstract harmonic analysis and for his discovery, in collaboration with Leonard Jimmie Savage, of the Hewitt–Savage zero–one law.
There is an introduction and then the books delves into chapters on race and nationality, social class, heredity, childhood, marriage, life, pathology, stature, pigments, other miscellaneous things, and a conclusion.
 Ellis begins by saying people had not been able to have an efficient comprehensive study of men and women before him.
 The "Dictionary of National Biography" had a large collection of descriptions of people, but it had been too unwieldy and large to be useful.
 Ellis then analyzes people and their natural tendencies to contribute successfully to society, but people born into royalty are excluded.
 They cannot be included with the rest of the population because they were given advantages at a young age that others were not given.
 The term genius is used to describe intelligence every time the word is mentioned throughout the text.
 He examines the concept of tracking down the origin of intelligence to a specific region of the world.
 In order to do this, each person must be asked about their birthplace to create an accurate record.
 The best way of asking though, is to ask each grandparent where they came from.
 In the chapter on social class, to determine the social class of people most precisely, it was best to ask the fathers what their occupation was.
 The occupation had to be considered at the time when the kid was born.
The Viola Concerto by William Walton was written in 1929 for the violist Lionel Tertis at the suggestion of Sir Thomas Beecham.
 The concerto carries the dedication "To Christabel" (Christabel McLaren, Lady Aberconway).
 But Tertis rejected the manuscript, and composer and violist Paul Hindemith gave the first performance.
 The work was greeted with enthusiasm.
 It brought Walton to the forefront of British classical music.
 In "The Manchester Guardian", Eric Blom wrote, "This young composer is a born genius" and said that it was tempting to call the concerto the best thing in recent music of any nationality.
 Tertis soon changed his mind and took the work up.
Leonard Jimmie Savage (born Leonard Ogashevitz; 20 November 1917 – 1 November 1971) was an American mathematician and statistician.
 Economist Milton Friedman said Savage was "one of the few people I have met whom I would unhesitatingly call a genius."
Multiple citizenship, also called dual citizenship or multiple nationality or dual nationality, is a person's citizenship status, in which a person is concurrently regarded as a citizen of more than one state under the laws of those states.
 There is no international convention which determines the nationality or citizen status of a person, which is defined exclusively by national laws, which vary and can be inconsistent with each other.
 Multiple citizenship arises because different countries use different, and not necessarily mutually exclusive, criteria for citizenship.
 Colloquial speech refers to people "holding" multiple citizenship but technically each nation makes a claim that this person be considered its national.
The Hewitt–Savage zero–one law is a theorem in probability theory, similar to Kolmogorov's zero–one law and the Borel–Cantelli lemma, that specifies that a certain type of event will either almost surely happen or almost surely not happen.
 It is sometimes known as the Hewitt–Savage law for symmetric events.
 It is named after Edwin Hewitt and Leonard Jimmie Savage.
