My favorite number is 7. Tell me something about it, John! ;D The 4th prime, third odd prime. Using my little theorem, you can prove that it's prime by noting the following: 7 = 4+3 4 = 2+2 = 1+3 3 = 1+2 1 X 2 does not equal 1 X 3 or 2 X 2 Of course, you could prove it about as quickly by simply trying and failing to divide it evenly by 2, 3, 5 and 6. Of course, 7 has all sorts of mystical associations. I'm not much into numerical mysticism, though one of the greatest mathematicians of all times, Pythagoras, was heavy into it, which shows that it is no impediment to doing great math and indeed motivated a lot of his work. Also, I do have a rather strange personal anecdote involving the numbers 7, 19 and 26 that I'll tell some day.

My favorite prime number is 2, since it is an even number and prime! I like even numbers best, especially 4 since my birthday is 4/4. Oh, so your favorite number is an even prime and my theoretical work is mostly on odd composites. I don't know, Cat. This could become a point of contention between us ... ;D Uh oh!! Watch out! I love my even numbers!

I love my even numbers! Well, the products of the numbers multiplied together in my compositionality proof are always even. Indeed, they are always multiples of 4 and specifically equal to a number A multiplied by the immediately following number A+1 times some other number B multiplied by the number immediately following THAT number B+1, hence: A x A+1 x B x B+1 = N Since one or the other of two consecutive numbers must be even, there are at least two even numbers amongst A, A+1, B and B+1 and any number with at least two even factors must be a multiple of 4!

I have very little understanding of the above, but it sounds like you are saying that the number 4 is even more special than I thought! :-)

I have very little understanding of the above, but it sounds like you are saying that the number 4 is even more special than I thought! :-) Oh, it's even more special than I let on here. This is a finished result. I am working on proving a conjecture which, if true, would mean that ALL multiples of 4 and ONLY them will bear a critical relationship to the all odd numbers that are composite and only the specifically composite odd numbers. The conjecture is: If AxB = CxD and A+B+C+D add up to an odd number, that odd number will be composite, not prime. When the above conditions hold, then the product of AxB, hence also of CxD, must be a multiple of 4. They could be odd only if all of A, B, C and D are odd, but then A+B+C+D would add up to an even, not an odd, number. They can only add up to an odd if an odd number of them is odd. But if three of them are odd and one even, one of AxB or CxD must be even and the other odd. Hence they can't be equal. Everything works only if only one of A, B, C or D is odd. But if that's so, then one of AxB or CxD has two even factors and hence is a multiple of 4. That means the other number must also be a multiple of 4 for the equivlance to hold. And since one the the factors in the second number is odd, the other factor must itself be a multiple of 4. This is of some significance, since this restriction significantly reduces the number of pairs of numbers you have to look at to confirm/disconfirm the equivalence. There will be a quiz on Monday. ;D

I would fail that quiz! Fascinating stuff, though!

Brain hurts... , if'n I had to do THIRD GRADE math again I'd still be there, not proud but there it is...back to literature...just finished "When You Lie About Your Age, The Terrorist's Win" and a bio of Caroline Kennedy...both excellent!!!!!!

Just started listening to The Power of Now on audio book. Really enjoying it so far. I listen before bed and just zen out. Very relaxing.

Just finished A Good and Happy Child, about a grown man who cannot bring himself to hold his newborn son and you don't know if he is mentally ill or possessed by a demon (most of the story takes place in his childhood when it first started). Creepy stuff. Halfway through House of Leaves. I think I really like, but man it isn't an easy read. Def. not for those who like linear stories. This one has footnotes that go on for pages (that as explained may or may not exist as actual sources), its inter cut with another story about someone's mental breakdowns following their reading of yet another story written by a blind man on scraps of paper and the backs of stamps. You have the story of Johnny Truant, the story of Zampano, and the story of the Navidson Report which itself veers off in many places to footnotes that may or may not exist or even apply!! The more you get into it the more interesting it gets visually, and I mean about the type. The word 'house' is always in blue, and some pages are written sideways/upsidedown/backward or a combination of those. Its funny the looks I get from people who must assume I can't read when they see me trying to read a book that is obviously upsidedown! Sometimes I have to put the book down because its too unsettling too close to bedtime, and sometimes I have to put it down because I'm dizzy, lol!

ps: House of Leaves author is brother to Poe, one of my favorite musicians. Her album 'Haunted' is basically a musical representation of the book. Mind you I had the album for years and never even knew!

You are the first person I know that has heard of her! She is amazing, and her album Haunted is beautiful and creepy. But yeah, it was really funny because in House of Leaves I saw the phrase "Five and a Half Minute Hallway" and all I could think of "What are the odds?", then I found out that the author is her brother!

I really cannot wait to pick up this book. And now I need to go home and listen to some Poe....LOL

"The Hunger Games" series by Susanne Collins. Aimed for young adults but holy cripes I had horrible dreams the entire time I was reading the books. Coming out as a movie next year and I'm beyond stoked. Can't recommend the books enough.

I remember Poe, but don't listen to her. I've always wanted to read House of Leaves.
My favorite series are George. R. R. Martin's A Song of Ice and Fire, Steig Larsson's Millennium trilogy, Orson Scott Card's Enderverse, and Harry Potter. Some of my favorite stand alones were Lost Boys by Orson Scott Card and The Thief of Always by Clive Barker.
I work in a library now, so my hands are on books a good part of the time. I just wish I had more time to read them!

I finished the Rob Lowe book a couple of weeks ago... Ace would be fun to read, Keith might be a bit scary to read! lol

Yeah, the Keith book is about quite a life...but it's written like he's sitting with you, a drink in one paw and a smoke in the other and just remembering back in the day...very well done...

I bought House of Leaves, can't wait to start it. (I still need to read White Trash Zombie, too....I'm so behind on reading).
