One of my longstanding peeves is that art museums are treated as serious places for grown-ups but science museums and zoos are treated as places for kids.
I think that science museums being places for kids is a good thing. The are the ones who benefit the most. If you want science for grownups, you have conferences. Also, that it is for kids doesn't make it impossible to enjoy as an adult, especially if it is about things you are unfamiliar with. Now, if you go to a science museum and think "only a kid can enjoy that". Then the problem is not that it is a place for kid…
I'm not sure how you can look at the current state of scientific literacy in America and conclude this.
> art museums, the problem is that they are usually just exhibitions, and to be honest, that's boring, especially if you are a kid
There are historical, thematic and philosophical aspects to art that make it beautiful beyond the aesthetic.
