I do not entirely disagree with the article but would like to point out that the apparent simplicity of mathematical formulae, like Einstein's field equations above, are to some extent illusory. Mathematics is a radical compression of logical and scientific language into a more economical set of conventional symbols, the meanings of which have evolved out of traditional use by specialized practitioners. Einstein is said to have called his summation notation his most significant contribution. I'm sure he said this tongue-in-cheek but it points to this important function of math practice. To the untrained, the field equations may appear simple, but they are completely mystifying because the layman does not possess the reams of background knowledge (which is not simple) to interpret the meaning of the symbols. These equations appear at once simple and meaningful only to the practiced expert who is able to implicitly expand their traditional symbols into the full and complex language of science and logic.
