Science is like a flashlight in the hands of people living in a huge balloon. They can illuminate anything in the balloon, but cannot shine it outside the balloon to see where it is floating - or if it is floating at all.

I was the kind of reader in smudged pink harlequin glasses sitting on the cool, dusty floor of the Arrandale public library, standing at the edge of the playground, having broken a tooth in dodge ball, and lying under my covers with a flashlight.

Brits and Americans have hundreds of different phrases for the same thing. Luckily, it's usually a source of amusement rather than frustration. A flashlight by any other name is still a torch. My personal favourite is 'fairy lights,' which we boringly refer to as 'Christmas lights.'
