Thirteen things that don’t make sense

Every so often I begin to think that we, as humans, are pretty good at knowing things. We’re smart and clever and are understanding a lot of what goes on. Then I read a book on quantum mechanics and realise we’re all still just making it up as we go along. This article in The New Scientist is a great reminder that we still have absolutely no idea how some fairly fundamental things about the world work. We know they work because we’ve seen them, but they’re unexplainable. And I like that.

Everything from the placebo effect, to the fact that the Pioneer space probes aren’t flying in the directions they should, to signals from space and cold fusion (remember that?) are discussed here. It’s gratifying to know that there are still huge chunks of the universe that we have absolutely no idea about, and that wonder and curiosity are still alive and well.
