Like the Speaker of the House, the Minority Leaders are typically experienced lawmakers when they win election to this position. When Nancy Pelosi, D-CA, became Minority Leader in the 108th Congress, she had served in the House nearly 20 years and had served as minority whip in the 107th Congress. When her predecessor, Richard Gephardt, D-MO, became minority leader in the 104th House, he had been in the House for almost 20 years, had served as chairman of the Democratic Caucus for four years, had been a 1988 presidential candidate, and had been majority leader from June 1989 until Republicans captured control of the House in the November 1994 elections. Gephardt's predecessor in the minority leadership position was Robert Michel, R-IL, who became GOP Leader in 1981 after spending 24 years in the House. Michel's predecessor, Republican John Rhodes of Arizona, was elected Minority Leader in 1973 after 20 years of House service.

As of the 2010 U.S. Census, there were 113,394 people, 45,634 households, and 21,704 families residing in the city. The population density was 4,270.33 people per square mile (2653.47/km²). There were 49,982 housing units at an average density of 1,748.0 per square mile (675.0/km²), making it less densely populated than inner-ring Detroit suburbs like Oak Park and Ferndale (and than Detroit proper), but more densely populated than outer-ring suburbs like Livonia or Troy. The racial makeup of the city was 73.0% White (70.4% non-Hispanic White), 7.7% Black or African American, 0.3% Native American, 14.4% Asian, 0.0% Pacific Islander, 1.0% from other races, and 3.6% from two or more races. Hispanic or Latino residents of any race were 4.1% of the population.

The axiomatization of mathematics, on the model of Euclid's Elements, had reached new levels of rigour and breadth at the end of the 19th century, particularly in arithmetic, thanks to the axiom schema of Richard Dedekind and Charles Sanders Peirce, and geometry, thanks to David Hilbert. At the beginning of the 20th century, efforts to base mathematics on naive set theory suffered a setback due to Russell's paradox (on the set of all sets that do not belong to themselves). The problem of an adequate axiomatization of set theory was resolved implicitly about twenty years later by Ernst Zermelo and Abraham Fraenkel. Zermelo–Fraenkel set theory provided a series of principles that allowed for the construction of the sets used in the everyday practice of mathematics. But they did not explicitly exclude the possibility of the existence of a set that belongs to itself. In his doctoral thesis of 1925, von Neumann demonstrated two techniques to exclude such sets—the axiom of foundation and the notion of class.

What 2 techniques did Von Neumann use to exclude sets in his doctoral thesis in 1925?
Answer:
the axiom of foundation and the notion of class.
