Re: [math-fun] Who wrote this paper?

Hi Steve: But as a fun teaser, everything you read about base golden ration

(1+sqrt(5))/2, it turns out for natural numbers the digits also represent the number in base (1-sqrt(5))/2, which is not something yet discussed in the literature.

It's not precisely the same, but I do dance around this in my expository paper on Jim's early rotor-router work, which appeared as a Mathematical Intelligencer column. Check out https://arxiv.org/abs/math/0501497. --Michael -- Forewarned is worth an octopus in the bush.
