I want to know the answer to the following question:
What was the topic of Von Neuman's thesis?
All the background I'm provided with is that "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.". Is that enough to answer the question?
