I like the European Science Museums. American Science Museums, I am sorry to say, are pretty seriously dumbed down: the assumption is that the audience consists basically of children who know NOTHING and have to have the basics explained, with plenty of room between displays for perspective, I guess. European Museums have displays that are much more compact, with much… much more. There are lots of interesting details, and especially interesting examples of things for those who have some background and can make the intellectual connections. The central museum area, much like the Smithsonian Mall, consists of a variety of extravagantly built structures, here centered around a huge statue of Empress Maria Theresa, the only female ruler of Austria during the regal period; she had 16 children, was on the throne for 40 years and pretty much established the governmental structure until the empire collapsed in 1918 with the end of WWI. The Museum of Natural History (Naturhistisches Museum) is the building beyond the statue.
