I'm planning on taking a brief trip to Budapest soon. Many hugely influential mathematicians and physicists were born there - Erdös, Teller, Szilard, Von Neumann, etc. - and I was wondering if there are any sites in the city that would be worth visiting for someone with a background in their work. This could be as simple as a plaque commemorating any of these individuals or as elaborate as one of the universities where they worked. I've been searching online and haven't turned anything up yet, though perhaps that's because I don't speak Hungarian. :-)
