Found this fascinating list of Things That Do Not Make Sense. Scientific things, that is.
I'll admit, some of them are over my head--I'm just not up on theoretical physics the way I should be--but other things, like homeopathy, I am fairly familiar with, and fascinated by the unknown quantity. I enjoy the unknown factor because it leaves room for the existence of yung yi (internal force).
Who was it said, Only a fool would say, "That's impossible?"
