[–] chx 9y ago ↗ It's incredibly fascinating how very simple constructs like primes have such complexity to them. It's very easy for a 14 year old to formulate questions relating to primes that noone can answer. [–] labster 9y ago ↗ Noone is a pretty smart guy. But there are questions that no one, not even he, can answer. [–] niccl 9y ago ↗ gnome Ann's best friend perhaps? https://xkcd.com/1704/ [–] mmanfrin 9y ago ↗ Noone is smart, but Anon is pithy. Anon came up with a ton of choice quotes and sayings, I wonder if he was a contemporary of Aesop?

[–] jason_slack 9y ago ↗ what I find interesting is the amount of computing power that it takes to calculate.Edit: As an after thought, there are recordings of million digit prime numbers: http://www.primegrid.com/download/SR5-180062.pdf
[–] gr3yh47 9y ago ↗ this is a great example of the title change rule making a title worsei think taglines/subtitles/subject sentences should be eligible for titles too
[–] pavel_lishin 9y ago ↗ Are there chains of Sophie Germain primes?e.g., p is prime 2p + 1 is prime 2(2p + 1) + 1 is prime... [–] teraflop 9y ago ↗ Wikipedia says these are called Cunningham chains: https://en.wikipedia.org/wiki/Cunningham_chainThere are no infinite chains, but there are conjectured to be inifinitely many finite chains of every possible length.

i think taglines/subtitles/subject sentences should be eligible for titles too
e.g.,
There are no infinite chains, but there are conjectured to be inifinitely many finite chains of every possible length.
