But your painting isn’t exactly thesame as the original – the red is a little too bright, that stroke is a little too heavy,there are a few too many atoms of carbon 14 in the new canvas, and so on – it’s acopy, but not a perfect one. Is a perfect copy, identical even at the subatomiclevel, even possib...
