Ever feel like you're not sure whether you're coming or going?
You could be in a "cat state":
This fall scientists announced that they had put a half dozen beryllium atoms into a "cat state."No, they were not sprawled along a sunny windowsill. To a physicist, a "cat state" is the condition of being two diametrically opposed conditions at once, like black and white, up and down, or dead and alive.
The universe: weirder even than cats.
