So what I could gather prime numbers are useful in crypto apps. If so then that is pretty useful, but why are primes useful in crypto and other numbers not so useful? i.e. why use a prime for crypto rather than a normal number? And don't worry, I already think mathematicians are a weird lot. regards, Paul Watson Bluegrass Cape Town, South Africa Do you Sonork?

Dear Paul [non-mathematician] Well, my math is not great either, but in crpto the use of primes has something to do with work-divisibility. Lets assume there is an operation X. And we need to calculate 20X3. We can divide it into T1=5X4 and then T2=T1X3 If we had a prime instead of 20 that wouldn't have been possible. Maybe I am wrong. That's just my non-mathematical view of things. Nish [non-mathematician] Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut

So Colin is giving me his usual run around on Sonork and this time he is off on the number theory or magical number tangent. Now I don't even pretend to know or like numbers. In fact my Math skills are about as long as John's fuse. So anyway Colin said that 12024562121 is a number with "style". To me it is a random collection of meaningless numbers. In fact if that was my credit card number I might be happier as at least it means something. So does anyone have a clue what is special about 12024562121 and in general what do you think of numbers and number theory? regards, Paul Watson Bluegrass Cape Town, South Africa Do you Sonork?

Paul Watson wrote: ? Are prime numbers used for a specific purpose e.g. computing the best way to make me rich or happy? Well, for one they are largely used in cryptography. Paul Watson wrote: Or are they simply amazing because they are prime numbers? It's worth to point out that math and science does not have to be usefull. In the end you never know where the design or the math idea will end up. Math is simply a way to describe the world around. Math is using numbers to describe it. Physics uses math to express the theories and so is many other science branches. If you think the prime numbers are strange try to take your run against 11-dimentional world. Hell, try with 4-dimentional first to warm up :) And yet such an abstraction is susefull to explain the origin of the Universe, would you believe? Take another sample - complex numbers. Is there such a thing as a square root of -1 (minus one)? And yet a large portion, if not all, of electronics is build up using complex numbers equations. There are many examples of the stuff like that. What seems to be strange suddenly appears usefull. That is what we call a pure research - you never know what you gonna get.

The fact that they are not divisible by any number than 1 or itself is and how this can be used to solve other problems (crypto comes to mind) is pretty amazing. One thing that I can't understand is why people are still chasing very large prime numbers. I mean, in algebra 101 I was taught how to prove that there is an infinite number of primes. The proof is very clear and has no logic traps. Then why are some mathematicians so eager to find bigger primes all the time? You can never go past infinity, so what's the point? It's scary when mathematicians break out in a big "YAAAAAHOOOOO!!!" whenever some large cluster crunch out a new "largest known mersienne prime".

(This is a very simplified version of why prime numbers are the way to go and it covers only asymmetric cryptography. Symmetric cryptography is a different animal if I'm not mistaken) Basically you want to hide the factors of a cryptographic key. If you can find a factor (keys used to produce the cipher) of a "cryptographic" number you have therefore divided the problem into a "solved" and a "smaller unsolved". Thus you don't want to give a potential cracker that kind of luxury, you wan't to make it as hard as possible for him/her. If you choose a prime number, then you cannot divide the problem so easily, you are forced to do a "brute force" crack, i.e. try all possible combinations. Of course, the real thing is a lot more complicated than what I just wrote, but in a very broad sense, this is the reason why prime numbers are nice. (Sidenote: Most cryptographic implementations does not necessarily use prime numbers. Since the numbers are so large, it would take ages to generate and/or verify a possible prime number. Therefore heuristic approaches are used in an iterative process. Most implementations are 99.999999999% accurate though)

When the dude who conquered everest was asked why, he said "because it is there". Same thing. Though I think the math guys are way lamer running after large primes than the guy who conquered mt everest. I wonder if they could put their number crunching to better use.
