After doing nearly all the coursework for a Ph.D. in math, I then did all the coursework for a Ph.D. in statistics and completed that degree.

@ToddTrimble : My posting says, in the first sentence in the second paragraph "Doubtless it's an interesting problem, to those who are interested in that sort of thing; otherwise Hilbert would not have included it in his list." That says it. But I was saying that even those who take no particular interest in that sort of thing can find Matiyasevich's theorem interesting because of the surprising nature of the result: that there are no semi-decidable sets except diophantine sets.

@Ryan : I don't think it's a precise definition with "may". And I state explictly in my posting that a set is decidable if and only if both it and its complement are semi-decidable, so that makes it clear if it weren't already that every decidable set is semi-decidable. That all decidable sets are semi-decidable is an easy exercise. ${}\qquad{}$

There is also a Wikipedia article, originally created by me: en.wikipedia.org/wiki/Proof_that_22/7_exceeds_%CF%80 ${}\qquad{}$

@BenjaminSteinberg : OK, so your point is simply to agree with my second paragraph?

There seem to be lots of problems in geometry, including this one, and the one in my posted question and the napkin ring problem, and others that escape me at the moment, that seem essentially the same as each other in all respects except the specifics. ${}\qquad{}$
