“everything  should be made as simple as possible. but not simpler.”


einstein never wrote or said it.
it is ironically a paraphrase of what he did say: “It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.”
