Something that’s always annoyed me is the story about how scientists have shown that bumblebees can’t fly. Everytime I hear the story, it’s always told with the same “stupid scientists” tone.
I see, via Cosmic Variance that scientists have finally found out how they manage the trick. (Interestingly, someone in the comments suggests that the original research showed not that bumblebees couldn’t fly, but that they couldn’t glide, which in fact they can’t.)
