 2007-03-28, 22:12 #1 kaldor   Mar 2007 216 Posts Simple graph to predict Primes A few months ago someone introduced me to the Prime numbers and basic problems associated with them. Not having a mathematical background I used Excel graphs to learn about the Primes. Last week I found a simple graphic system of finding the Primes (by identifying the non Primes). The system shows that the apparent randomness of the Primes results from the superpositioning of many layers of very orderly and predictable sets of number. The systems seems fairly efficient and identifies the non Primes in sections between the squares of consecutive Primes (the squares of the Primes identified in earlier sections). I believe that formulas predicting the location of the Primes can be developed from these . I consider this finding a personal success for someone not in the field of mathematics. I am sure that this system is already available but just in case I would like to hear the oppinion of experts like you.

 2007-03-30, 19:20 #6 kaldor   Mar 2007 2 Posts Thank you for your kind replay. I checked the Eratosthenes sieve and found that you are correct. My graph is based on the same principles. Hoewer I do believe that the sieve I am working with has some useful features. I am having fun so I will continue my search.

Well, it's good that you're having fun and learning a few useful things, to boot. But around here we've seen the sieve of E. in so many disguises advertised as a "huge prime breakthough!!!", I hope you don't mind if we have little fun now, too.

"It's not just a sieve ... it also doubles as handy colander! Set it into a 4-quart cookpot and you get an instant steamer -- makes perfect steamed vegetables every time! Kill harmful E Coli bacteria while keeping all of the nutritious vitamins of your favorite vegetables!! Even the kids will eat their veggies now, all while you discover the next world-record prime number!!!

And that's not all: Order NOW and get a FREE POCKET-SIZED POTATO SLICER!! It slices, it dices, it makes those perfect Julienne Fries every time! No more greasy fried potatoes ... and all this is yours with only32582657 easy payments of \$19.95 -- Order Now!!!!!!

 2007-04-06, 09:06 #8 mfgoode Bronze Medalist     Jan 2004 Mumbai,India 22·33·19 Posts Sieve and free potato slicer! In Mumbai we have a lot of ants-black ants, red ants and white ants. They are all over the place-ants even in one's pants ! I have two strainers (sieves if you like) to strain out the drowned red ants in an uncovered vessel of coffee. Somehow these ants also get in under covered vessels. Talk of intelligence? Yeah you cant beat an ant ! If only one gets into an elephant's ears it could drive the poor animal insane. So to separate them we use two strainers -one medium and one of fine mesh to remove the really small ones. So I'm having ant flavoured coffee daily. They say they are good for the eyes! I wish you all the best with your new found sieve and if it does'nt work try sieveing ants. You may learn something from them in sieivng primes! Mally

Well Dave I did. I was fed up with seeing it stagnant since March (?)
Well when Logic fails in this forum I find the thread degenerates and borders on ridicule and posters are given a free reign to put in their 2 cent bit!
So why not have a go ?
