Since there were few posts in Hungary for mathematicians, and those were not well-paid, his father wanted von Neumann to follow him into industry and therefore invest his time in a more financially useful endeavor than mathematics. So it was decided that the best career path was to become a chemical engineer. This was not something that von Neumann had much knowledge of, so it was arranged for him to take a two-year non-degree course in chemistry at the University of Berlin, after which he sat the entrance exam to the prestigious ETH Zurich, which he passed in September 1923. At the same time, von Neumann also entered Pazmany Peter University in Budapest, as a Ph.D. candidate in mathematics. For his thesis, he chose to produce an axiomatization of Cantor's set theory. He passed his final examinations for his Ph.D. soon after graduating from ETH Zurich in 1926. He then went to the University of Gottingen on a grant from the Rockefeller Foundation to study mathematics under David Hilbert.
What was the topic of Von Neuman's thesis?

The city's municipal government was dominated by about 1215 merchant families, whose wealth came from overseas trade with continental Europe in particular the export of wool and hides and the import of salt, iron and wine.

At the turn of the 21st century, a post-punk revival developed in British and American alternative and indie rock, which soon started appearing in other countries, as well. The earliest sign of a revival was the emergence of various underground bands in the mid-'90s. However, the first commercially successful bands the Strokes, Franz Ferdinand, Interpol, Neils Children and Editors surfaced in the late 1990s to early 2000s, as did several dance-oriented bands such as the Rapture, Radio 4 and LCD Soundsystem. Additionally, some darker post-punk bands began to appear in the indie music scene in the 2010s, including Cold Cave, She Wants Revenge, Eagulls, the Soft Moon, She Past Away and Light Asylum, who were also affiliated with the darkwave revival, as well as A Place to Bury Strangers, who combined early post-punk and shoegaze. These bands tend to draw a fanbase who are a combination of the indie music subculture, older post-punk fans and the current goth subculture. In the 2010s, Savages played a music reminiscent of early British post-punk bands of the late '70s.
