Andrica's conjecture on the gap between root primes

19+ hour, 42+ min ago  (94+ words) I recently found out about Andrica's conjecture: the square roots of consecutive primes are less than 1 apart. In symbols, Andrica's conjecture says that if pn and pn+1 are consecutive prime numbers, then "pn+1 " "pn < 1. This has been empirically verified for…...
