[edit] extremely poor wording
In what has to be the worst wording of a math concept I've ever seen, the article currently states: "His pupil Theaetetus made the generalization that the side of any square, represented by a surd, was incommensurable with the linear unit." For god's sake, why not just say what he did in plain english? Theaetetus showed that the ratio of an irrational to a rational can never be as the ratio of a rational to a rational, and vice versa. In particular, he is credited by Euclid for Elements book 10 #9.
But, perhaps more to the point, if you're just going to list a single thing that Theodorus' pupil Theaetetus is known for, why not just mention that he was the guy who discovered the last two platonic solids? That certainly seems like a bigger deal to me, since no one talks about commensurability anymore, but everyone knows the platonic solids. — Eric Herboso 07:30, 21 January 2008 (UTC)

- People know the solids, but people know of Theordorus' mathematcal work from this particular issue: The irrationality of the roots of non-square integers from 3 through 17 inclusive, and the fanciful attempts to explain what his approach must have been. But adding to it would be great. I'm indifferent about the "surd" language--it's linked, and incommensurable probably should be linked to irrationality or something too.
