"Translation is like a reverse-engineering process--whereby, say, we might take apart a clock made of metal parts in order to build a functioning replica made entirely of plastic. Our final product will not look the same as the original clock, and it would be impossible to simply copy the designs of its inner workings, because plastic and metals have very different properties. For example, we cannot make small plastic springs or very thin gears of plastic. But these changes do not matter; the only thing that matters is that our replica will tell the time correctly."--From the...
