seven and thirteen7 and 13 are the first two happy primes and 91 (7×13) is also a happy number. this means that 19 is happy, this is the 3rd happy prime! Why did the chicken cross the Mobius Band? To get to the other ...um...!!! #2 20090608 22:00:11
Re: seven and thirteenWhat are happy primes? Character is who you are when no one is looking. #3 20090608 22:33:47
Re: seven and thirteenHappy numbers are related to a sequence where each term is determined by the sum of the squares of the previous term's digits. eg. Why did the vector cross the road? It wanted to be normal. #4 20090610 16:36:13
Re: seven and thirteenHmm.. Never heard of this.. Is there a use for this sequence? #5 20090614 00:59:52

Re: seven and thirteenHi Rick; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #7 20090614 22:37:05

Re: seven and thirteen
I don't appreciate what you are trying to do here. The meaning... what are you implying? Last edited by bobbym (20090617 03:11:49) In mathematics, you don't understand things.

Re: seven and thirteenThere are two different accounts posting here, both RICKisanidiot and RICKYisanidiot, imo a clear violence to the multiple account rule (which I think exist on this forum?)
