Von Neumann's habilitation was completed on December 13, 1927, and he started his lectures as a privatdozent at the University of Berlin in 1928. By the end of 1927, von Neumann had published twelve major papers in mathematics, and by the end of 1929, thirty-two papers, at a rate of nearly one major paper per month. His reputed powers of speedy, massive memorization and recall allowed him to recite volumes of information, and even entire directories, with ease. In 1929, he briefly became a privatdozent at the University of Hamburg, where the prospects of becoming a tenured professor were better, but in October of that year a better offer presented itself when he was invited to Princeton University in Princeton, New Jersey.

How many papers had Von Neumann written by 1929?

After a visit to Brasilia, the French writer Simone de Beauvoir complained that all of its superquadras exuded "the same air of elegant monotony," and other observers have equated the city's large open lawns, plazas, and fields to wastelands. As the city has matured, some of these have gained adornments, and many have been improved by landscaping, giving some observers a sense of "humanized" spaciousness. Although not fully accomplished, the "Brasilia utopia" has produced a city of relatively high quality of life, in which the citizens live in forested areas with sporting and leisure structure (the superquadras) flanked by small commercial areas, bookstores and cafes; the city is famous for its cuisine and efficiency of transit.

Who complained that Brasilia was monotonous?
Answer: Simone de Beauvoir

In 1980 half of all the industrial jobs in Mexico were located in Mexico City. Under relentless growth, the Mexico City government could barely keep up with services. Villagers from the countryside who continued to pour into the city to escape poverty only compounded the city's problems. With no housing available, they took over lands surrounding the city, creating huge shantytowns that extended for many miles. This caused serious air pollution in Mexico City and water pollution problems, as well as subsidence due to overextraction of groundwater. Air and water pollution has been contained and improved in several areas due to government programs, the renovation of vehicles and the modernization of public transportation.

How many of the industrial jobs in the county were based in Mexico City in the late 20th century?
Answer:
half
