41

ok, so what is so fascinating about the number 41 (other than that its sort of beginning of mid-life crisis). I was reading Rama II by Arthur C. Clark and came across this great fact about the number 41. Starting from 41, you can create a series of numbers, 41, 43, 47, 53... which are all consecutive primes. The series ends at square of 41, containing exactly 41 numbers!! Numbers just never fail to surprise you.
