surprise surprise! an application of the theory of finite fields! as a high-level programmer (e.g. web development) I don't think to hard about the coding theory that goes into me sending a simple e-mail or a text. Or a tweet. Certa

John Conway has a very interesting theory of "tangles" where he associates a continued fraction to a wide class of kntots http://www.maths.ed.ac.uk/~aar/papers/conway.pdf There is also the Conway Tessela

so why was he calling the Veteran's crisis line?

the continued fraction of (1+√5)/2 is [1;1,1,1,1,1,1,...] it goes on forever. there are more advanced formulas in this article of Curtis McMullen http://www.math.harvard.edu/~ctm/papers/home/text/pap

I have heard that double-buffering is an excellent solution to a number of data-stream problems. Are there any resources on StackOverflow explaining such things?

The only map I can think of from the sphere to the plane (and periodically tiles) uses genus 0 Riemann surfaces and quadratic differentials. And I know he didn't do that. Nonetheless, there's a fascinating work by Anton Zorich ca
