This piece of quantum weirdness caught my eye in The Economist recently.

After which all I can do is quote my hero, the redoubtable Richard Feynmann, from The Character Of Physical Law (1965):

Do not keep saying to yourself, if you can possibly avoid it, "But how can it be like that?" because you will get "down the drain," into a blind alley from which nobody has yet escaped. Nobody knows how it can be like that.
