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.
Noone is a pretty smart guy. But there are questions that no one, not even he, can answer.

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?
what I find interesting is the amount of computing power that it takes to calculate.

Are there chains of Sophie Germain primes?
e.g.,
Wikipedia says these are called Cunningham chains: https://en.wikipedia.org/wiki/Cunningham_chain
There are no infinite chains, but there are conjectured to be inifinitely many finite chains of every possible length.
